It relates to an automatic paging device by unmanned monitoring.

Most conventional monitoring devices (e.g., devices that detect whether intruders, fires and gas leaks, etc. have occurred in a predetermined place, or devices that detect temperature in a greenhouse or a poultry farm) have predetermined outputs from the respective sensors. When a signal is generated, it is configured to drive an alarm device installed near or remotely.

Therefore, if any abnormality occurs in a certain place, the user or monitor can recognize it by the operation of the alarm device, but in this case, the user must know that the alarm device is close to the alarm device. Even if it is driven, there is a problem that you do not know exactly where the abnormality occurred.

In addition, the complex system as described above has a problem that the installation cost is high because the control device connected to each sensor is connected to the alarm device through a separate dedicated line.

It is to provide an automatic paging device by unmanned surveillance that can notify the user through the user immediately recognizes the movement state regardless of the location.

Another object of the present invention is to notify the user of the correct abnormal state and the time received by notifying the user's telephone number and code number corresponding to the abnormal state together with the time notified when the abnormal state is automatically transmitted to the pager. It is to provide an automatic paging device by unmanned surveillance that can take the corresponding emergency measures.

Characterized in that composed of a microcomputer (36) for sending out each of the abnormal status display code with the telephone number installed in the area.

Here, reference numeral 37 denotes a rectifier which is composed of a power transformer (T), a diode (D4), a regulator (IC), and a smoothing capacitor (C) to rectify the AC voltage to a DC voltage and apply it to each part, and I1-I7 is half. Electricity.

Referring to the effect of the present invention configured as described above are as follows.

First, the oscillator 11 is continuously driven as long as a predetermined output voltage is supplied from the rectifier 25 to generate a clock pulse of a predetermined frequency as shown in FIG. The frequency is divided into half (about 1 Hz) through the period 12, and then input to the 4-bit counter 13.

At this time, the counter 13 outputs the output signal of the ninth and gate 22 when a predetermined output signal is not generated from the JK flip-flops 7-9 having the respective sensors 1-3 connected to the clock terminal. Reset to maintain an uncounted state.

In addition, the sensors 1-3 include an intruder detection sensor, a fire detection sensor, a gas leak detection sensor and a temperature sensor for detecting the temperature of the greenhouse or poultry farm, etc., each of the sensors 1-3 has a respective purpose. When it detects a state corresponding to, it sends a high signal.

Since the detection signal output from the sensor 1-3 may include a noise signal in the vicinity of the transmission, the noise in the detection signal through the first to the third differentiator 4-6 composed of a resistor and a capacitor, respectively. Remove it.

As such, when the output signal of the sensors 1-3 is input to the clock terminal CLK of the JK flip-flop 7-9 with noise removed through the first to third differentiators 4-6, the JK In the output terminal of the flip-flop 7-9, a high signal is output as shown in (b) of FIG.

That is, when a high signal is output from a predetermined one of the sensors 1-3, a high signal is generated at the output terminal of the JK flip-flop corresponding to the sensor among the several JK flip-flops 7-9, and thus several diodes are used. The OR gate 10 composed of (D1-D3) outputs a high signal even if a high signal is output only in any one of the JK flip-flops 7-9.

Since the 4-bit counter 13 is enabled when the high signal is output from the output terminal of the OR gate 10, the output pulse of the first ½ divider 12 input from the clock terminal CP is inputted from this time. As the counting starts, the output terminal Q0-Q3 of the 4-bit counter 13 generates an output signal as shown in FIG.

When the initial pulse is input and the high signal is output only at the output terminal Q0 of the counter 13 (that is, one pulse is output), the first AND gate having the inverters I1 to I3 connected to the three input terminals Since a high signal is output from the output terminal of FIG. 14 as shown in (d) of FIG. 2, a trigger signal of about 400 ms is generated from the first trigger signal generator 23 composed of a monostable multivibrator, and thus the output terminal of the microcomputer 36 is output. The first photo coupler 27 connected to the telephone hookswitch on / off terminal of is driven.

Accordingly, the microcomputer 36 recognizes the hook switch on signal through the first pulse in (e) of FIG. 2 output from the first photo coupler 27 and turns on the hook switch of the telephone.

In addition, since the output signal of the first AND gate 14 is also applied to the clock terminal of the second half divider 33, the output signal Q 'of the second half divider 33 becomes a low signal.

Since the output signal of the second half divider 33 is input to the third trigger signal generator 25 after the noise is removed through the fourth differentiator 34, the output terminal of FIG. As shown in the figure, the counter 13 maintains a low state until 15 counting is completed.

Subsequently, when the high signal is output only at the output terminal Q1 of the counter 13 by the input of the second pulse, the third AND gate having the inverters I4-I6 connected to the remaining input terminals except the second input terminal. Since the high signal is output from the output terminal of (16), the second photo coupler 28 is driven to input the high signal such as (g) of FIG. 2 to the wireless pager call terminal of the microcomputer 36. Recognizing this, the speed dialing of the subscriber number for a predetermined pager stored in itself is performed through the telephone in the hookswitch on state.

After 12 seconds of dialing to the pager, a response signal is sent from the pager. When the telephone and pager are connected normally, a predetermined AC voltage is transmitted through the telephone line (Tel L). Even if it is made, the person who wears the pager does not transmit the AC voltage unless the telephone and the pager are connected to each other by the place where the wireless communication is impossible.

When the telephone and the pager are normally connected and a predetermined AC voltage is input from the CO line, the rectifier 25 rectifies the output and outputs the DC voltage. Therefore, the sixth photo coupler 32 is driven to drive the fourth trigger signal generator. In (26), a predetermined trigger signal (i.e., a trigger signal as shown in (i) of FIG. 2) indicating that there is a response of the pager is generated so as to be input to one input terminal of the fifth end gate 18 having two input terminals. Is approved.

On the other hand, the fourth end gate 17 in which the inverter I7 is installed in only one of the third input terminals among the four input terminals outputs a high signal as shown in (h) of FIG. 2 when the counter 13 is 13. Done.

Accordingly, the fifth end gate 18 outputs a high signal only when the thirteenth counting is performed while the telephone and the pager are normally connected.

As such, when the high signal is output from the fifth end gate 18, the other input terminal of the sixth through eighth end gates 19-21 connected to the output terminal of the JK flip-flop 7-9 is connected to one input terminal. Since the high signal is applied to each of the sensors, the high signal is output only to the corresponding end gate to the sensor among the sixth to eighth end gates 19 to 21 according to which sensor 1-3 is detected.

For example, if an intruder is generated at a predetermined place and a predetermined output signal is generated from the intruder detecting signal sensor 1, the high 'signal is output from the JK flip-flop 7 and the sixth end gate 19 connected thereto. The third photo coupler 29 of the third to fifth photo couplers 29-31 having an input terminal connected to an output terminal of the sixth to eighth end gates 19-21 is driven to intruder code terminals of the microcomputer 36. A signal as shown in FIG. 2 (j) is input to the input signal.

Accordingly, the microcomputer 36 transmits a code indicating that an intruder is generated with its own phone number to a wireless pager in which a telephone is connected within an 11-character range (eg, home phone number + intruder code 11111). Therefore, the remote pager owner can easily recognize through the pager what kind of abnormality is occurring at present and quickly take necessary action.

At this time, the wireless pager is notified of the abnormal state and the time to be notified since the time of notification is displayed together with the telephone number and the code number corresponding to the abnormal state.

Of course, when the fire detection sensor 2 or the gas leak detection sensor 2 among the sensors 1-3 operates, the output of the seventh and eighth gate gates or the eighth gate gate 21 becomes high. Therefore, the fourth or fifth photo couplers 30 and 31 are driven, and the microcomputer 36 transmits a code for notifying a fire or a code for noting gas leakage to the wireless pager together with its own phone number.

In the present invention, three sensors are installed for convenience and the corresponding codes are transmitted. However, when the temperature sensor installed in the greenhouse or poultry farm is detected, the corresponding codes may be sent out when a predetermined temperature or less is detected. It can also be applied to automation equipment and dangerous goods monitoring.

In addition, when the high signal is output from the fifth and gate 18 as described above, the trigger signal of the high state is generated from the second trigger signal generator 24 and is applied to one input terminal of the ninth and gate 22. .

When the high signal is output from the output terminals Q0-Q3 of the counter 13 by the 15th pulse input as shown in (e) of FIG. 2, the first trigger signal generator 23 generates the second signal. Since the second pulse is output from (f) to drive the first photo coupler 27, the microcomputer 36 recognizes this and outputs a hook switch off signal to the telephone.

At the same time, the high signal output from the fifth and gate 18 is also applied to the second half frequency divider 33, so that the output of the third trigger signal generator 25 under control is the rear end of the second diagram (k). As shown in FIG. 2, the reset signal is generated in the high state as shown in (1) of FIG.

Thus, the 4-bit counter 13 and the second half dividers 33, including several J-K flip-flops 7-9, are reset and returned to their initial state.

However, when the microcomputer 36 dials to a predetermined pager after the hook switch is turned on, and there is no response signal due to a busy communication or wireless communication, the output of the fifth end gate 18 remains low. Since the reset signal is not transmitted from the ninth end gate 22, the counter 13 is looped and repeats the above process while counting 15 pulses from the beginning.

That is, if there is no response from the pager, the above procedure is repeated until the answer page is sent from the pager (of course, the response signal is emitted from the telephone exchange). As soon as the user moves to an area where communication is possible, the abnormal condition can be known so that the user can be notified of the abnormal condition as soon as possible and take appropriate action.

On the other hand, the device of the present invention may be formed separately from the phone, and may be incorporated in the phone other than the sensor (1-3), in this case, the phone can be used as a normal phone.

As described above, according to the present invention, when intruders, fires, and gas leaks occur in general homes and important facilities, or the temperature of greenhouses and poultry farms is lowered below a predetermined temperature, the sensors are detected. By immediately notifying the pager with the phone number where any abnormality has occurred, the user can recognize the abnormal condition accurately and take the appropriate action promptly regardless of the location, resulting from various disasters. It is possible to prevent potential loss of life and property, and to significantly reduce the cost of installing the monitoring system.
