Referring to fig. 1, a block diagram of a circuit of an embodiment of a weather-adaptive wiper for an emergency command vehicle according to the present invention is shown. The weather adaptive windshield wiper for the emergency command vehicle can comprise a windshield wiper control circuit 110, a rotating motor 120, a windshield wiper 130 and a measuring mechanism, wherein the measuring mechanism can comprise a box body 200 with an opening at the upper end as shown in fig. 2, the bottom of the box body 200 is provided with a first opening, the first opening is connected with a timing electromagnetic valve 140, the timing electromagnetic valve 140 is connected with the windshield wiper control circuit 110, and the timing electromagnetic valve 140 can be switched on and off at fixed time; a liquid level sensor 150 and a distance sensor 160 are arranged on the side wall of the box body 200, a pressure sensor 170 is arranged on the front windshield of the emergency command vehicle, and a vehicle controller 180, the liquid level sensor 150, the distance sensor 160, the pressure sensor 170 and the rotating motor 120 of the emergency command vehicle are all connected with the wiper control circuit 110; the vehicle controller 180 is configured to send vehicle driving state information to the wiper control circuit 110; the liquid level sensor 150 is used for sending the detected liquid level information in the box body 200 to the wiper control circuit 110; the distance sensor 160 is used for detecting the distance between the distance sensor and the deposited dust in the box body 200 and sending the distance information to the wiper control circuit 110; the pressure sensor 170 is configured to send detected pressure information of the front windshield to the wiper control circuit 110; when the wiper control circuit 110 detects that the vehicle is in a driving state, the rotating speed of the rotating motor 120 is adjusted according to the liquid level information and the distance information, so that the rotating motor 120 drives the wiper 130 to rotate according to the adjusted rotating speed; and correcting the closing time of the timing electromagnetic valve 140 according to the pressure information, the liquid level information and the distance information, and correcting the rotating speed of the rotating motor according to the corrected closing time.
The wiper control circuit 110 includes a first comparator 111, a second comparator 112 and a wiper controller 113, as shown in fig. 3, a first input end of the first comparator 111 is connected to the liquid level sensor 150, the remaining input ends are connected to corresponding preset liquid level voltages V1-1 to V1-n, n is an integer greater than 1, the preset liquid level voltages V1-1 to V1-n are gradually increased, output ends of the first comparator 111 are connected to corresponding first input ends of the wiper controller 113, and a first output end of the wiper controller 113 is connected to the rotating motor 120; the wiper controller 113 is configured to control the rotating motor 120 to drive the wiper 130 to rotate according to a corresponding rotation speed when the liquid level voltage detected by the liquid level sensor 150 is greater than a corresponding preset liquid level voltage, and the rotation speed of the rotating motor 120 increases along with an increase of the liquid level voltage detected by the liquid level sensor 150.
In this embodiment, the wiper controller 133 may locally store a first initial correspondence relationship between the number of bits of which the first input terminal receives the high level and the rotation speed of the rotating electrical machine in advance. When the liquid level voltage detected by the liquid level sensor 150 is greater than the corresponding preset liquid level voltage, the first comparator 111 provides a high level to the corresponding first input terminal of the wiper controller 113, and then the wiper controller 113 first finds out a rotation speed corresponding to the number of bits of the high level received by the current first input terminal from the first initial corresponding relationship, and then controls the rotating motor 120 to drive the wiper 130 to rotate according to the found out corresponding rotation speed. For example, in the process of traveling to a disaster area, if a rainy weather occurs, the box 200 may collect rainwater, when the liquid level voltage detected by the liquid level sensor 150 in the box 200 is greater than the minimum preset liquid level voltage V1-1, it indicates that the rainfall falling onto the front windshield may affect the view of the driver at present, one output end of the first comparator 111 provides a high level to the corresponding first input end of the wiper controller 133, thereafter, the wiper controller 133 may first traverse through whether each first input end connected to the liquid level sensor 150 receives a high level, determine the number of bits (at this time, 1-bit number) of the first input end that receives a high level, then find out the rotating speed of the rotating motor corresponding to the 1-bit number from the first initial corresponding relationship, and control the rotating motor 120 to drive the wiper 130 to rotate according to the found rotating speed. For another example, when the liquid level voltage detected by the liquid level sensor 150 in the box 200 is greater than the preset liquid level voltage V1-2, indicating that the rainfall falling onto the front windshield glass at present is still affected if the wiper rotates according to the previous rotation speed, two output ends of the first comparator 111 provide a high level to the corresponding first input end of the wiper controller 133, and then the wiper controller 133 may also first traverse each first input end connected to the liquid level sensor 150 to determine whether the first input end receiving the high level receives the high level (at this time, 2 digits), find the rotation speed of the rotary motor corresponding to the 2 digits from the first initial corresponding relationship, control the rotary motor 120 to drive the wiper 130 to rotate according to the found rotation speed, and so on. Therefore, the rotating speed of the windshield wiper can be adjusted based on the rainfall, so that the self-adaptive rotation of the windshield wiper on the rainfall weather is realized.
The first input end of the second comparator 112 is connected to the distance sensor 160, the remaining input ends are connected to corresponding preset distance voltages V2-1 to V2-n, n is an integer greater than 1, each preset distance voltage V2-1 to V2-n is gradually decreased, each output end of the second comparator 112 is connected to a corresponding second input end of the wiper controller 113, the wiper controller 113 is configured to control the rotating motor 120 to drive the wiper 130 to rotate according to a corresponding rotating speed when the distance voltage detected by the distance sensor 160 is less than the corresponding preset distance voltage, and the rotating speed of the rotating motor 120 is increased along with the decrease of the distance voltage detected by the distance sensor 160.
In this embodiment, the wiper controller 133 may locally pre-store a second initial corresponding relationship between the number of bits whose second input terminal receives the high level and the rotation speed of the rotating electrical machine. When the distance voltage detected by the distance sensor 160 is smaller than the corresponding preset distance voltage, the second comparator 112 provides a high level to the corresponding second input terminal of the wiper controller 113, and then the wiper controller 113 first finds a rotation speed corresponding to the number of bits of the high level received by the current second input terminal from the second initial corresponding relationship, and then controls the rotating motor 120 to drive the wiper 130 to rotate according to the found corresponding rotation speed. For example, in the process of an emergency vehicle heading to a disaster area, if a sand storm weather occurs, the box 200 may collect sand, when the distance voltage detected by the distance sensor 160 in the box 200 is less than the maximum preset liquid level voltage V2-1, it indicates that the amount of sand falling onto the front windshield may affect the visual field of the driver, one output end of the second comparator 112 provides a high level to a corresponding second input end of the wiper controller 133, then the wiper controller 133 may traverse whether each second input end connected to the distance sensor 160 receives the high level, determine the number of bits (at this time, the number of 1 bit) of the second input end receiving the high level, find out the rotating speed of the rotary motor corresponding to the number of 1 bit from the second initial corresponding relationship, and control the rotary motor 120 to drive the wiper 130 to rotate according to the found rotating speed. For another example, when the distance voltage detected by the distance sensor 160 in the box 200 is less than the preset liquid level voltage V2-2, which indicates that the amount of dust falling onto the front windshield is large, if the wiper rotates according to the previous rotation speed, the visual field of the driver is still affected, two output ends of the second comparator 112 provide a high level to a corresponding second input end of the wiper controller 133, and then the wiper controller 133 may traverse through each second input end connected to the distance sensor 160 to determine whether the second input end receiving the high level receives the high level (at this time, 2 digits), find the rotation speed of the rotating motor corresponding to the 2 digits from the second initial corresponding relationship, control the rotating motor 120 to drive the wiper 130 to rotate according to the found rotation speed, and so on. Therefore, the rotating speed of the windshield wiper can be adjusted based on the amount of the dust, so that the windshield wiper can rotate in a self-adaptive manner in the sand storm weather.
Although the above wiper can satisfy the adaptive rotation adjustment in two main weathers, namely rainfall weather and sandstorm weather, due to the limited size of the box body, when the rainfall is large and the sandstorm weather is severe, rainwater or sand possibly overflows from the box body within the initial closing time of the timing electromagnetic valve, so that the adjustment range of the rotating speed of the wiper is limited, namely the rotating speed of the wiper can only be switched between the rotating speeds of the rotating motors stored locally in the wiper controller 133, and obviously, in order to satisfy the adjustment accuracy, the adjustment range is small. Therefore, the pressure sensor 170 is arranged on the front windshield of the emergency command vehicle, the closing time of the timing electromagnetic valve 140 is corrected by utilizing the pressure information detected by the pressure sensor 170, the liquid level information detected by the liquid level sensor 150 and the distance information detected by the distance sensor 160, so as to ensure that rainwater or sand and dust cannot overflow from the box body, and after the closing time of the timing electromagnetic valve 140 is corrected, the rotating speed of the rotating motor 120 can be corrected, so that the rotating speed adjusting range and the adjusting precision of the windshield wiper can be improved.
The wiper control circuit further includes a third comparator 114, a first input end of the third comparator 114 is connected to the pressure sensor 170, the remaining input ends are connected to corresponding preset pressure voltages V3-1 to V3-n, n is an integer greater than 1, the preset pressure voltages V3-1 to V3-n are gradually increased, each output end of the third comparator 114 is connected to a corresponding third input end of the wiper controller 113, and a second output end of the wiper controller 113 is connected to the timing solenoid valve 140; the wiper controller 113 is configured to enable the second output terminal of the wiper controller 113 when the liquid level voltage detected by the liquid level sensor 150 is greater than a maximum preset liquid level voltage V1-n or the distance voltage detected by the distance sensor 160 is less than a minimum preset distance voltage V2-n, and modify the closing time of the timing solenoid valve to a corresponding value through the second output terminal thereof when the pressure voltage is greater than a corresponding preset pressure voltage, wherein the closing time is shorter as the pressure voltage increases; and correcting the rotating speed of the rotating motor according to the corrected closing time length.
In this embodiment, the wiper controller 113 may locally pre-store a first correction correspondence between the number of bits of which the third input terminal receives the high level and the closing time of the timing solenoid valve, and a second correction correspondence between each closing time and the rotating speed correction coefficient of the rotating electrical machine. The third comparator 114 provides a high level to a corresponding third input terminal of the wiper controller 113 when the pressure voltage detected by the pressure sensor 170 is greater than a corresponding preset pressure voltage. Then, the wiper controller 113 first finds out the closing duration of the timing electromagnetic valve corresponding to the number of bits of the high level received by the current third input end from the first correction corresponding relationship, and corrects the closing duration of the timing electromagnetic valve to the found closing duration; and determining a rotating speed correction coefficient of the rotating motor corresponding to the searched closing duration from the second correction corresponding relation, and correcting the adjusted rotating speed of the rotating motor according to the correction coefficient.
Specifically, in the process of traveling to the disaster area, if the rain or sand storm occurs, the box 200 collects rain or sand, and when the liquid level voltage detected by the liquid level sensor 150 in the box 200 is greater than the maximum preset liquid level voltage V1-n or the distance voltage detected by the distance sensor 160 is less than the minimum preset distance voltage V2-n, it indicates that the rain or sand collected in the box 200 may overflow when the timing solenoid valve is in the original closing time, and at this time, the wiper controller 113 enables the second output end thereof, i.e., the closing time of the timing solenoid valve 140 can be corrected. Thereafter, the wiper controller 113 may traverse whether each of the third input terminals connected to the pressure sensor 170 receives a high level, determine the number of bits of the third input terminal receiving the high level, then find the closing duration of the timing solenoid valve corresponding to the number of bits from the first corrected correspondence, and correct the closing duration of the timing solenoid valve to the found closing duration. Then, the wiper controller 113 may determine a rotating speed correction coefficient of the rotating electrical machine corresponding to the searched closing time from the second correction correspondence, and then first adjust the rotating speed of the rotating electrical machine 120 according to the liquid level information and the distance information to determine the adjusted rotating speed of the rotating electrical machine, and then multiply the adjusted rotating speed of the rotating electrical machine by the determined correction coefficient, so that the rotating electrical machine 120 drives the wiper 130 to rotate according to the corrected rotating speed.
In addition, hail weather may be encountered during driving, for this reason, when the pressure voltage detected by the pressure sensor 170 is greater than the maximum preset pressure voltage, each third input terminal of the wiper controller 113 receives a high level, and at this time, the wiper controller 113 controls the rotation speed of the rotating motor 120 to be adjusted to a corresponding safe value, so as to prevent the wiper from being broken by hail during the rotation process. In order to better collect rainwater, sand and dust, the side wall of the box body can be also provided with an opening which extends from the outer edge and is vertical to the front windshield.
According to the embodiment, the rotating speed of the windshield wiper can be adjusted based on the rainfall, so that the self-adaptive rotation of the windshield wiper on the rainfall weather is realized; the rotating speed of the windshield wiper can be adjusted based on the amount of the sand and dust, so that the self-adaptive rotation of the windshield wiper on the sand storm weather is realized; can revise when timing solenoid's closure based on pressure sensor to guarantee that rainwater or dust can not spill over from the box, and revise the back when timing solenoid's closure is long, can also revise the rotational speed of rotating electrical machines, thereby can improve the rotational speed control range and the regulation precision of windshield wiper. The windshield wiper can realize weather self-adaptation, so that the condition that the emergency command vehicle needs to manually operate the windshield wiper in the driving process is avoided, and the safety of the emergency command vehicle in the process of going to a disaster area is improved.
