Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to home electric appliances and various control devices.

[0002]

2. Description of the Related Art Conventionally, the following techniques have been proposed as a device for improving the service to the user by detecting the external environment or the state of the user and correspondingly changing the operation command of the device. Has been done.

First, Japanese Laid-Open Patent Publication No. 61-193919 discloses an air conditioner for an automobile in which a sensor for detecting the number of passengers and a seating position is provided on the ceiling and the control system is changed according to the detection signals. Japanese Patent Laid-Open No. 3-1031 has the same purpose.
It is also described in Japanese Patent No. 139413.

In Japanese Patent Laid-Open No. 1-127839, a superconducting magnetoresistive element detects the intensity of an ultra-weak magnetic field associated with a weak current generated by the brain to determine a sleep state, and blows air accordingly. A redirecting air conditioner is described. Further, Japanese Patent Laid-Open No. 121644/1989 describes an air conditioner control device which detects a perspiration state as personal physical condition data and changes a driving method. Japanese Unexamined Patent Publication No. 2-154940 discloses an air conditioner control device that takes in a user's request by voice and changes a control command.

As a method for adaptively changing the driving characteristics of a vehicle to the outside world, there is a method described in US Pat. No. 4,829,434, which is based on environmental conditions such as vehicle speed, remaining fuel amount, weather, road and traffic. Depending on the expected function of the car,
There is a method of automatically correcting and changing according to the mood and personal driving style.

[0006]

The above-mentioned method has the following problems.

First, Japanese Patent Application Laid-Open No. 61-193919 and Japanese Patent Application Laid-Open No.
In the case of 3-139413, the control specification can be changed according to the number of users of the device, but the control specification cannot be optimized according to the individuality of the user. Also, in the case of Japanese Patent Laid-Open No. 1-127839, although the general relationship regarding the state of the electroencephalogram and the sleeping state, and the appropriate wind direction is stored in the device,
There is no mention of adapting the device to the personality of the user and further optimizing the control commands in fine detail. Also in Japanese Patent Laid-Open No. 121644/1989, because the method of controlling the air conditioner is changed according to the general relationship with the sweating state, the difference in how the user feels heat and how to sweat is different. Is not considered, and the optimization of the control command corresponding to the individuality of the user is not described. Japanese Patent Laid-Open No. 2-154940 discloses that the interface between the device and the air conditioner is performed by voice, but the user needs to continue to send a voice signal until the operation method of the air conditioner is optimized, and the operation is performed. There is a problem that it is not good.

Further, although US Pat. No. 4,829,434 describes that the function of each part of the automobile is learned and adapted to the user on the basis of the past history of personal behavioral habits and preferences, For these functions, the driving user
No consideration is given to controlling by reflecting information about how they are currently feeling. Therefore, it is possible to perform uniform control according to the past history, but there is a problem that it is not possible to meet the demand such as "I want to raise the temperature control a little because I have a slight cold today". Also, in the process of updating the control command by learning, if there is a situation in which the device cannot be properly adapted to the user due to inadequate learning signal due to user's erroneous operation, etc. In such a case, an unexpected value may be output from the device because sufficient consideration is not given to guaranteeing a stable output. Furthermore, since no consideration is given to the reuse of the accumulated learning results or the sharing of information with other cars, when a new car is purchased, a certain learning period is required to suit the user. Will be needed. During this time, it is disadvantageous for the user to be forced to drive a vehicle that is not well adapted to him.

The object of the present invention is to adjust the sensitivity of the user.
It is to provide a control device capable of performing fine control.

[0010]

According to the present invention, information about the outside world such as room temperature, humidity, temperature difference between the outside and the room, information about the user such as pulse of the user, degree of sweating, blood pressure, body temperature, and the like, The input means for inputting the driving method set by the user, the storage means for holding the relationship between the external information, the information about the user and the driving method set by the user, and the storage means stored in the storage means Based on the identification means for identifying the relationship of various input information input by the input means based on the relationship and the information about the user input by the input means, the user's satisfaction or comfort level with respect to the operating state of the device, etc. In the control device, a sensibility determining means for quantifying the user's sensibility and outputting as a sensitivity value, and a command generating means for outputting a driving command based on the output of the identifying means and the output of the sensitivity determining means are provided in the control device. A. In addition, specifically, the identification means is composed of a neural network, and the outside information such as room temperature, humidity, temperature difference between the outside and the room, which is stored in the storage means,
Information about the user, such as the user's pulse, the degree of sweating, blood pressure, and body temperature, is input, and the driving method set by the user is output to determine the weight of each neuron in the neural network by learning.

[0011]

According to the present invention, the operating method set by the user is such that the identification means stores information on the outside world such as room temperature, humidity, temperature difference between the outside and the inside of the storage means,
Information about the user, such as the user's pulse, the degree of sweating, blood pressure, and body temperature, is input, and the relationship between these inputs and outputs, which is the output of the driving method set by the user, is identified. That is, based on the information stored in the storage means, when the external information and the information about the user are given, an algorithm for outputting a driving command expected to be set to the device by the user is generated. In addition, the sensitivity determination unit quantifies the user's sensitivity such as satisfaction or comfort level of the user with respect to the operating state of the device based on the input information about the user, and outputs it as a sensitivity value. That is, from the input information about the user, what kind of sensation the user is currently having with respect to the operating state of the device (how the user feels with respect to the operating state of the device) is determined. Further, the command generation means obtains and outputs a driving command based on the sensitivity value output from the identification means and the sensitivity determination means.

As a result, since the driving command is determined according to the user's sensitivity, fine control is possible.

[0013]

The present invention will be described in detail below with reference to the drawings.
FIG. 1 shows a configuration example of an apparatus which is an embodiment of the present invention. The device 100 includes an input unit 101, a storage unit 102, and an identification unit 10.
3, a first command generation unit 104, a sensitivity determination unit 105, a sensitivity table 106, a second command generation unit 107, an output calculation unit 108, and an output unit 109. First, the operation of the entire apparatus will be briefly described, and then the detailed operation of each unit will be described.

The input section 101 includes an external switch group 110,
It is composed of a first sensor group 111 and a second sensor group 112. In the input unit 101, the operating method of the device set by the user as the first input information is the switch 110, the external information is the second input information from the first sensor group, and the third sensor
Information for sensitivity determination is input from the second sensor group 112 as the input information of the. The first input information is input from the external switch group 110 or the like provided in the apparatus when the user starts the operation of the apparatus or wants to change the operation method. The other two pieces of input information are the first sensor group 1 corresponding to the device 100 with the timer period as a starting point.
It collects autonomously via 11 and the 2nd sensor group 112. The storage unit 102 fetches and stores the first input information and the corresponding second input information and third input information at the timing when the first input information is fetched. The identification unit 103 identifies the relationship between the first input information, the second input information, and the third input information, using the information stored in the storage unit 102. That is, an algorithm for deriving the driving method of the device 100 expected to be set by the user is constructed from the second input information and the third input information. The constructed algorithm is sent to the first command generation unit 104. The first command generation unit 104 follows the algorithm based on the second input information and the third input information fetched via the input unit 101, according to the device 1
The operation method of 00 is output. The sensitivity determination unit 105 is the third
From the input information of and the sensitivity table 106, the user is
The degree of satisfaction with the operation of the device 100 is quantified, and the second command generation unit 107 is quantified in the form of satisfaction or the like.
Output to. In the sensitivity table 106, the degree of satisfaction corresponding to each value of the third input information is tabulated. The second command generation unit 107 includes the sensitivity determination unit 1
According to the output of 05, the output of the first command generation unit 104 is finely adjusted in the direction in which the degree of satisfaction of the user becomes higher.
The output of the second command generation unit 107 becomes the final command value for operating the device 100. According to this command, the output calculation unit 108 determines the output of the device 100 and outputs it from the output unit 109.

The identifying unit 103, the first command generating unit 104, the second command generating unit 107, and the sensitivity determining unit 10 are used.
5 and the output operation unit 108 are configured by one computer, and the processing function of each of these units can be realized by either hardware or software, but in order to downsize the device configuration, it is realized by software. It is desirable to do.

Assuming that the device 100 is an air conditioner (air conditioner), the operation of the entire device will be briefly described again. In this case, the first input information is set values such as temperature, wind speed, and inclination of the fan, and the second input information is room temperature, humidity, temperature difference between indoor and outdoor, and the like. The third input information is the degree of sweating of the user, the heart rate, the complexion, and the like. The storage unit 102 stores these values and the values of the second and third input information at the timing when the user sets the set value of the temperature and the wind speed. The identification unit 103 includes the storage unit 10.
2nd and 3rd based on the data accumulated in 2
The relationship between the input information of 1 and the first input information is identified. Based on this identification result, the first command generator takes in room temperature, humidity, temperature difference between indoor and outdoor, sweating degree of user, heart rate, complexion, etc., and sets temperature of air conditioner, wind speed,
Determines command values such as fan inclination. Sensitivity determination unit 105
Of the input information, takes in only the third input information (the degree of sweating of the user, the heart rate, the facial color, etc.). Further, based on these, the user's comfort level (degree of heat, cold, comfort, etc.) corresponding to each input amount registered in the sensitivity table 106 is referred to. Then, the comfort level (sensitivity determination result) is quantified by an appropriate combining process, and is output to the second command generation unit 107 as a comprehensive comfort level. The second command generation unit 107 uses the first command generation unit 1 according to the overall comfort level.
Finely adjust the output of 04. For example, the first command generator 1
When the overall comfort level is "slightly hot" in response to the 04 command, the temperature setting value is slightly lowered and the wind speed is slightly raised. This processing determines the final command value.
The output calculation unit 108 performs regulator control based on this command value, and controls the rotation speed of the inverter that drives the compressor and the position of the motor that drives the fan. As a result, the output unit 108 outputs the air at the appropriate temperature at the appropriate wind speed and direction.

Next, the operation of each section will be described in detail. The specific part will be described on the assumption that the device 100 is an air conditioner. FIG. 2 shows the information stored in the storage unit 102. The first input information is output to the storage unit 102, and the second input information and the third input information corresponding to the first input information are stored as input, together with the date and time when they were captured. Therefore, m corresponds to the total of the second input information and the third input information, and n corresponds to the total of the first input information. The date and time may be omitted if the application is sufficient to simply identify the inputs and outputs.

FIG. 3 shows the configuration of the identification unit 103. FIG. 3 shows an example in which identification is performed using the learning function of the neural network, which comprises a learning unit 301, an input layer 302 of the neural network, an intermediate layer 303, and an output layer 304. Each layer is composed of a plurality of neurons 305, and neurons in adjacent layers are connected by synapses 306. Although FIG. 3 shows a network having a three-layer structure which is usually used most often, it is also possible to use a multilayer neural network having four or more layers. First, the learning unit 301 extracts one of the input and output pairs stored in the storage unit 102. Then, by inputting m inputs to the corresponding neurons of the input layer 302 and propagating a predetermined calculation result to the downstream layer, the output of each neuron in the output layer is finally determined. Finally, the learning unit 301 detects the difference between this output value and the output value stored in the storage unit 102 corresponding to the input input, and the synapse weight value Wkj is set so that the difference value becomes 0. And update Wik. Many literatures can refer to the calculation method of each neuron and neural network, and the calculation to reduce the difference value.
For example, a flowchart is described in "Introduction and Learning Neurocomputer" (Technical Review Co., Ltd.) P47.

FIG. 4 shows the configuration of the first command generator 104. Similarly, an example in which a three-layer neural network is used is shown. The command generation unit 104 takes in the weight of each synapse of the network that has finished learning from the identification unit 103,
The weight of the corresponding synapse. Then, the second input information and the third input information are taken into the input layer, the above-mentioned calculation is performed, and then the operation command of the device is output from the output layer.

In FIGS. 3 and 4, an example of identifying the relationship between the input and the output by using the learning function of the neural network is shown. However, it is identified by the method of multivariate analysis represented by the linear multiple regression analysis. May be. In addition to this, the identification method is
There are various methods such as the maximum likelihood estimation method for selecting a model using the AIC, but all of them can be easily realized by the existing technology. FIG. 5 shows the configurations of the sensitivity determination unit 105 and the sensitivity table 106. The sensitivity table 106 stores the sensitivity levels corresponding to the degree of sweating of the user, the heart rate, the complexion, and the like, as the sensitivity determination information acquired from the second sensor group 112 of the input unit 101. In the figure, for example, the case where the heart rate is 55 is associated with "comfort", and the user feels that more than that is hot and less than that is cold. In FIG. 5, the most comfortable state is defined as “comfort degree = 0”, the state where the user feels hot is “comfort degree <0”, and the state where the user feels cold is “comfort degree> 0”. . The sensitivity determination unit 105 comprehensively determines how comfortable the user is currently based on the comfort level (sensitivity level) corresponding to each input (sensitivity determination information). For example, as shown in FIG. 5, the final sensitivity determination result is obtained by adding the sensitivity frequencies obtained from the respective sensitivity determination information and dividing by the number of the sensitivity determination information (the number of the third input information).

FIG. 6 shows the configuration of the second command generator 107. The second command generation unit 107 receives each command value that is the output of the first command generation unit, finely adjusts it according to the output of the sensitivity determination unit 105, and outputs it as a new command value. Various methods are selected according to the actual object, but the method of multiplying the comfort level or the square of comfort level by the definition of a1, a2, etc., or a special function such as exp (comfort level) is used. A method can be considered.

FIG. 7 shows an output calculation unit 108 and an output unit 109.
Shows the configuration of. The output calculation unit 108 calculates the output of the device 100 for the device 100 to realize the command value that is the output of the second command generation unit 107. Taking an air conditioner as an example, it takes in command values for temperature, wind speed, and fan inclination,
The measured values detected by the sensor 113 are compared. Then, the control units 701 to 703 perform feedback control based on the obtained deviation, and determine the operation amount to the compressor 704 and the motors 705 and 706. As a result of the control, the output unit 109 outputs the air having the predetermined temperature and the wind speed from the fan having the predetermined inclination.

FIG. 8 shows a method of updating the contents of the sensitivity table 106. The contents are updated at the timing when the user sets the operation method of the device. First, in S8-1, the setting of the driving method is detected. When the driving method is updated by the setting, in S8-2, the setting contents are interpreted, that is, the user's sensitivity is determined. In the case of an air conditioner, it corresponds to a determination as to whether the user has changed the set value because he or she felt it was hot or when it was cold. Next, in S8-3, it is determined whether or not the content of the sensitivity table needs to be changed for each input amount. For example, when the user feels cold and changes the setting of the driving method, it is assumed that the heart rate input at this time is a value corresponding to hot in the sensitivity table 106 of FIG. In such a case, in S8-4, the relationship between the heart rate and the comfort level is changed as shown in FIG. That is, the axis of heart rate is slightly shifted to the right. There are various conceivable amounts of change, such as a value proportional to the distance between the table contents and the user's operation. A standard person's value may be given as an initial value of the sensitivity table 106.

FIG. 10 shows a method for stably updating the contents of the sensitivity table 106. In FIG. 10, S10-1
Through S10-3 are the same as S10-1 through S10-3 in FIG. In S10-4, in the contents of the table,
Determine the amount to change. Then, in S10-5, when this exceeds the permissible value of the change amount, the amount to be changed is stored and the content update of the sensitivity table 106 is temporarily suspended. And when the user makes the same setting again,
The contents of the sensitivity table 106 are updated again. The number of times the driving method is set by the user necessary to suspend the update may be three or more.

FIG. 11 shows an example in which a limiter 1101 is provided at the output of the second command generator 107. The output of the second command generation unit 107 is transmitted to the output calculation unit 108 via the limiter 1101. The limiter 1101 has an output characteristic as shown in FIG. 12 with respect to the input from the second command generator 107. That is, when the input is from a1 to a2, the input value is output as it is, but when the input is smaller than a1, the value is a1, and when the input is larger than a2, the value is a2.
Clip each value.

FIG. 13 shows the limiter set values (a1, a2
An example of an algorithm for autonomously changing (the value of) by learning is shown. First, in S13-1, it is detected that the user has set the output value. If detected, S13-2, S1
At 3-3, it is determined whether or not the user's set value is in the saturation range of the limiter's set value. If the set value is in the saturation region, the process of saturating the set value of the limiter is performed in S13-4 and S13-5. The degree of relaxation is a
It can be set to an appropriate value by adjusting 0.

In S13-6, the relaxed set value is set to an initial value (a0 for a1 and a2, respectively) with an appropriate time constant.
1, a02) is performed. The time constant is α1,
Set with the value of α2. If return is not necessary, S1
The processing of 3-6 may be omitted. FIG. 14 shows an example in which the limiter setting value change is performed by interrupt processing.
The processing consists of a mail routine and a subroutine.
In the main routine, only the process of bringing the limiter setting value closer to the initial value is performed. That is, in S14-1, it is detected whether it is the timing to correct the set value of the limiter toward the initial value. In the case of the correction timing, S14-
In step 2, the processing for this is performed. When the user sets the output value, an interrupt signal is issued, and in S14-3 and S14-4, it is determined whether the value set by the user is caught in the saturation region of the limiter. If the set value is in the saturation region, S14-5, S14-
At 6, the processing for relaxing the set value of the limiter is performed. In the algorithms of FIGS. 13 and 14, the target value for limiter recovery is set to the initial value (a01, a02). However, after detecting that the user's setting value is frequently caught in the saturation region of the limiter setting value, the target value is detected. It is also possible to change. That is, in this case, a value with a slight relaxation of the limiter is set as a new target value.

FIG. 15 shows an embodiment provided with a switch 1501 for setting the update timing of the contents of the first command generator 104. At the timing instructed by the switch 1501, the identification unit 103 performs the above-described identification processing on the relationship between the input and output pairs stored in the storage unit 102. Then, the identification result is transferred to the first command generation unit 104, and the content is updated. In this embodiment, the external switch 1501 is provided so that the user can set the timing for updating the contents of the first command generation unit 104.
The update process may be automatically performed when the device 100 is started up or at rest. Also, starting from the timer interrupt,
The identification process may be performed at regular intervals. In FIG. 16, the first

Corresponding to these, the fingerprint recognition device 1705, the image processing device 1706, the voice processing device 1707, and the electroencephalogram processing device 17
08 is provided. The fingerprint input device 1701 receives the user's fingerprint and sends the information to the fingerprint recognition device 1705. The fingerprint recognition device 1705 identifies the user based on the received information. The camera 1702 captures the contour and facial expression of the user's face and sends it to the image processing apparatus 1706. The image processing device 1706 identifies the user based on the received information. The sound collecting microphone 1703 captures the voice of the user and sends it to the voice processing device 1707. The voice processing device 1707 analyzes the received voice to identify the user. The electroencephalogram detection device 1704 captures the electroencephalogram of the user and sends it to the electroencephalogram processing device 1708. The electroencephalogram processing device 1708 identifies the user based on this. The user identification result is sent to the algorithm changeover switch 1602. The input unit 1
01 and the various processing devices to be provided in the user identifying unit 1601 may include all of the devices described in FIG.
It may be limited to the necessary items. Further, a body shape detecting device for the user and a device for detecting other characteristic information may be provided. In addition, the user is identified by the user identification section 1
The judgment may be made comprehensively from the users suggested by the plurality of devices provided in the device 601, or may be made according to the result of the device that outputs the specific result with the highest certainty factor. Further, the user may be indirectly judged from the various sensor information described in FIG. 17, but the user may have a structure in which the user can identify himself / herself to the apparatus 100 by using a switch or the like.

FIG. 18 shows a structure of the apparatus 100 which can be simultaneously adapted to a plurality of users. First command generation unit 104
Is a command generator 1603 suitable for the user 1 and the user 2
, A command generator 1605 adapted to the user n. User identification unit 16
01 is a method described above, and identifies the user of the apparatus 100. Output command generation unit 1 output by the output arbitration unit 1802
The outputs of 603 to 1605 are weighted, and the values obtained by multiplying the outputs by the weights are added, and the second command generation unit 10
Output to 7. The value of each weight is determined by receiving the output of the user identifying unit 1601 between the output adjusting units 1802. That is, for example, when the user 1 and the user 2 share the device, if W1 and W2 are both set to 0.5 and the other is set to 0, a command value in which the sensitivities of both are moderately generated can be generated.

FIG. 19 shows the storage unit 102 and the sensitivity table 1.
An embodiment will be described in which the information stored in 06 can be retrieved from the device 101. The figure shows an example in which information can be inserted and removed as a personal card (IC card or the like). The personal card 1901 stores the contents of the storage unit 102 and the sensitivity table 106. The personal card reading unit 1902 decodes the information in the storage unit 102 and the sensitivity table 106 stored in the personal card 1901 and displays the contents on the display 1903 or the printer 1904. As a configuration, the storage unit 102 and the sensitivity table 106 used for operating the apparatus may be directly removed as the personal card 1901, or the personal card 1901 may be inserted into the apparatus 100 at a timing when information is to be taken out and the contents are read out. The method may be used.

FIG. 20 shows an example in which the contents of the personal card 1901 are limited to a part of the storage unit 102 and the contents of the sensitivity table 106. In the figure, among the contents stored in the storage unit 102, only the sensitivity determination information (information acquired from the second sensor group) and the date and time when this is input are stored in the personal card 1901. If the personal card 1901 is used as a history storage device for sensitivity information, the content of the personal card can be reduced in weight by limiting the content as described above.

FIG. 21 shows an example in which the personal card 1901 is shared by a plurality of devices. The personal computer 1901 is provided with a common interface between the devices 1 to n, and is configured to be removable. This can be easily realized by standardizing the hardware specifications of the personal card 1901 and the format of the stored data. As a result, the sensitivity information individually stored in each device can be shared among the devices and used. Further, when the device 1 is discarded, the contents of the storage unit 102 and the sensitivity table 106 stored in the device 1 can be transplanted to another device, so that another device can be used in a state suitable for the user from the beginning. .

FIG. 22 shows an embodiment in which the device 100 is provided with a function for generating a biorhythm. The biorhythm generation unit 2201 inputs the current time from the clock unit 2202,
Generate a corresponding user biorhythm. The clustering unit 2202 classifies the generated biorhythms into an appropriate number of categories (n in the example). That is, it is determined which one of biorhythm 1 to biorhythm n the generated biorhythm belongs to. The first command generation unit 104 includes biorhythm 1 to biorhythm n.
Command generators 2204 to 2206 corresponding to are separately provided. Algorithm switch 1602
Selects the first command generator corresponding to the biorhythm cluster identified by the classification. A plurality of command generation units 2204 to 220 included in the first command generation unit
