In an implementation mode, the bus communication node box can be a communication relay module, which is responsible for communication information receiving and forwarding; in another implementation mode, the bus communication node box is a connection wire of the communication bus, so that each communication device can be connected to the communication bus. The isolation communication module is used for isolating the communication signals between the bus communication node box and the processor, so that the communication level is not unstable when the detection or output module is working, and the receiving and transmitting work of the communication data of the processor is not affected. The human body sensing module is used for detecting whether there is a human body near the cabin door, and representing the human body information near the cabin door in the form of distance data; when there is a user in front of the cabin door, the distance data is transmitted to the bus communication node box through the communication bus.

By arranging the CAN isolation chip, the devices on the communication bus are not affected by the level abnormality of the individual device, that is, the stability of the data communication is improved, thereby providing a basis for the stable control of the hatch.

[0079] According to the embodiment of the present application, the human body sensing module comprises:

[0080] at least one human body sensing element;

[0081] The human body sensing element is an infrared sensing module or a microwave radar module.

[0082] The human body sensing element is connected in communication with the bus communication node box through a CAN bus.

[0083] It should be noted that the mobile communication vehicle is provided with at least one human body sensing element for qualitatively and quantitatively analyzing the human body activities near the communication vehicle, that is, detecting whether there is human body activity and the distance of the human body activity. The human body sensing element is a device component for detecting and responding to the human body activity or existence, in order to improve the measurement accuracy, at least one human body sensing element can be arranged at each hatch. The human body sensing element used in the present application is an infrared sensing module or a microwave radar module. The infrared sensing module works by sensing the heat emitted by the human body, analyzes the infrared radiation received by the sensor, and judges whether there is human body activity. The microwave radar module senses the human body through microwave signals, and can realize long-distance detection and penetration through obstacles such as walls. In the present application, the measurement data of the human body sensing element is transmitted to the bus communication node box through the CAN bus, and finally transmitted to the processor for calculating the distance information from the human body sensing element to the human body activity.

[0084] It is worth mentioning that it also includes:

[0085] The human body sensing element is an image recognition device.

[0086] It should be noted that the human body sensing element is an image recognition device, and the human body activity can be recognized by the image recognition device. As an embodiment, the image in front of the cabin door of the mobile communication vehicle is collected by a camera; then, the shape, size and other characteristics of the human body in the image are recognized and judged by image processing recognition technology, whether it is human activity.

[0087] According to the embodiment of the present application, the cabin door control module comprises:

[0089] The current detection unit detects the working current information of the motor and sends the current information to the bus communication node box through the CAN bus;

[0090] The rotating speed detection unit detects the rotating speed information of the motor and sends the rotating speed information to the bus communication node box through the CAN bus;

[0091] The height detection unit detects the height information of the cabin door and sends the height information to the bus communication node box through the CAN bus;

[0093] It should be noted that the cabin door control module is used to detect the first running state information of the cabin door, and sends the first running state information to the bus communication node box through the communication bus; then, the first running control information sent from the bus communication node box is received through the communication bus, so as to control the running of the cabin door. The first running state information at least includes the working current of the cabin door motor, the rotating speed of the cabin door motor, and the current height information of the cabin door. Among them, the working current and the rotating speed of the cabin door motor can reflect the running state of the opening or closing of the cabin door, and the height information of the cabin door can reflect the number of turns that the cabin door motor still needs to rotate. The cabin door control module collects the running state of the cabin door in real time through the current detection unit, the rotating speed detection unit and the height detection unit, and sends the cabin door state information to the bus communication node box through the CAN bus, and finally to the processor. The processor calculates and determines the control information of the motor according to the first running state information of the cabin door, including but not limited to the rotating speed of the cabin door motor, the rotating direction of the cabin door motor, and the working current of the cabin door motor, so as to realize the real-time regulation and control of the cabin door of the mobile communication vehicle. The present application realizes the accurate control of the cabin door motor by real-time detection and feedback control.

[0094] Please refer to Figure 2 , Figure 2A schematic diagram of the motorized communication vehicle electric cabin door control method provided by the embodiment of the present application is shown.

[0095] As shown in Figure 2 The second aspect of the present application discloses the motorized communication vehicle electric cabin door control method, and the method comprises:

[0096] S202, acquiring the first human body information;

[0097] S204, judging whether the first human body information is lower than a first distance threshold value;

[0098] S206, if yes, acquiring first height information and second height information;

[0099] S208, calculating the difference between the first height information and the second height information to obtain first height difference information;

[0100] S210, obtaining first speed information according to the height difference information;

[0101] S212, acquiring second speed information;

[0102] S214, determining a first speed adjustment amount according to the first speed information and the second speed information;

[0103] S216, generating and sending the second communication instruction information according to the first speed adjustment amount.

[0104] It should be noted that the first height information is a target opening height of the hatch door; the second height information is a real-time opening height of the hatch door; the first speed information is a target rotating speed of the motor; the second speed information is a real-time rotating speed of the motor; and the first speed adjustment amount is an adjustment signal for controlling the rotating speed of the motor. The first human body information is the distance from the human body sensing module to the detected human body. First, when the measured first human body information is lower than a preset first distance threshold, it indicates that the user is close to the communication hatch door and reaches the distance range of the hatch door opening and closing operation. When the human body moves in the preset distance range, the current height difference between the hatch door and the target height is measured and calculated in real time to obtain the first height difference information, which is used to represent the height of the hatch door that still needs to be adjusted. According to the first height difference information, the speed corresponding table stored in the processor is searched to obtain the corresponding target speed, that is, the target rotating speed of the hatch motor. Then, the real-time rotating speed of the hatch motor, that is, the second speed information, is measured and obtained. By comparing the real-time rotating speed of the hatch motor with the target rotating speed, the rotating speed adjustment control amount of the hatch motor, that is, the first speed adjustment amount, is determined. In actual application, the rotating speed of the motor is usually adjusted by adjusting the voltage value or the duty cycle of the pulse width modulation (PWM) to achieve the effect of adjusting the rotating speed of the motor, that is, the first speed adjustment amount can be the voltage adjustment value or the duty cycle adjustment value of the PWM. Finally, the second communication instruction information is generated according to the first speed adjustment amount, and is sent to the bus communication interface box through the communication bus to be transmitted to the hatch control module to realize the control of the rotating speed of the hatch motor. The real-time detection state is used to realize the accurate control of the hatch motor in a feedback control manner, and the stability of the hatch operation is improved.

[0105] Please refer to Figure 3 , Figure 3 A first human body information acquisition flowchart provided by an embodiment of the present application is shown.

[0106] As Figure 3 shown, in the embodiment of the present application, it further includes:

[0107] S302, when the human body sensing element is an infrared sensing module;

[0108] S304, infrared thermal radiation information is acquired through CAN bus communication;

[0109] S306, first temperature information and first distance information are obtained according to the infrared thermal radiation information;

[0110] S308, it is judged whether the first temperature information is within a preset temperature range;

[0111] S310, if yes, the first human body information is set according to the first distance information.

[0112] It should be noted that the first temperature information is a temperature value of the measured object surface calculated according to the infrared thermal radiation information; and the first distance information is a distance from the measured object to the infrared sensing module calculated according to the infrared thermal radiation information. When the human body sensing element is the infrared sensing module, the infrared sensing module works by sensing the heat emitted by the human body, and analyzes the infrared radiation received by the sensor to determine whether there is human activity. First, the infrared sensing module detects the infrared thermal radiation information, and sends the infrared thermal radiation information to the bus communication interface box through CAN bus communication, and then transmits the infrared thermal radiation information to the processor. Then, the processor processes and analyzes the infrared thermal radiation information, and determines whether it is human activity according to the temperature value and temperature change profile of the thermal radiation, that is, whether the obtained first temperature information is within the preset temperature range. If yes, it can be determined that there is human activity; wherein, in actual application, the preset temperature range can be set to 32-40℃ as an embodiment. Finally, the first distance information obtained from the infrared thermal radiation information, that is, the distance information of the human body to the human body sensing element when the human body activity is detected in the thermal radiation information, is set as the first human body information.

[0113] Please refer to Figure 4 , Figure 4 Another flowchart for acquiring the first human body information is shown.

[0114] As Figure 4 shown, in the embodiment of the present application, it further includes:

[0115] S402, when the human body sensing element is a microwave radar module;

[0116] S404, acquiring the microwave signal according to the preset time period;

[0117] S406, quantifying the first microwave information according to the microwave signal;

[0118] S408, comparing the first microwave information of each time period to determine whether there is object movement;

[0119] S410, if yes, obtaining the second distance information according to the first microwave information of the latest time period;

[0120] S412, setting the first human body information according to the second distance information.

[0121] It should be noted that the first microwave information is a digital value obtained by quantizing the microwave signal; and the second distance information is a distance from the measured object to the microwave radar module calculated according to the microwave model. When the human body sensing element is a microwave radar module, human body sensing is performed by transmitting and receiving microwave signals. First, after the microwave radar module receives the microwave signal feedback by the object in front, the feedback microwave signal is quantized by an analog-to-digital converter to obtain the first microwave information; the size of the first microwave information can reflect the strength of the signal feedback by the physical object. By setting the wavelength of the microwave radar signal, the wavelength sensitive to the human body is adjusted, so that the feedback microwave signal when detecting the human body is stronger. By comparing the first microwave information obtained in each time period, it is determined whether it shows an upward trend; if so, it indicates that there is an object that is getting closer and closer, and at this time, the second distance information is calculated according to the first microwave information of the last acquisition period and a preset intensity-distance relationship. Finally, the second distance information is set as the first human body information.

[0122] In the embodiments of the present application, further comprising:

[0123] Obtaining the second speed information;

[0124] Obtaining the first speed information according to the second speed information;

[0125] According to the first speed threshold information, a preset torque-current corresponding table is searched to obtain first current threshold information;

[0126] Obtaining the first current information;

[0127] Determining whether the first current information exceeds the first current threshold information;

[0128] If so, the first speed adjustment amount of the second communication instruction information is set to zero or the motor is reversed.

[0129] It should be noted that, in the running process of the hatch motor, since the hatch as a load usually uses relatively thick and heavy materials, the load intensity borne by the motor is different at different running speeds, that is, the required torque is different; according to the preset speed-torque relationship, the maximum torque threshold required to be borne by the motor at the current speed can be obtained through the real-time running speed of the motor, that is, the first torque threshold information. Then, according to the torque-current relationship set according to the characteristics of the motor itself, the first current threshold information is calculated; that is, the maximum current of the motor at the current speed should not exceed the first current threshold information. Finally, the real-time working current value of the hatch motor, that is, the first current information, is obtained; if the first current information exceeds the first current threshold information, it indicates that the load of the hatch motor has exceeded the load intensity brought by the hatch itself, and there is an object blocking the operation of the hatch; at this time, the intelligent anti-pinch function is triggered; the processor stops the rotation of the hatch motor or reverses the rotation to avoid damaging the object.

[0130] In the embodiments of the present application, further comprising:

[0131] Obtaining the first human body information;

[0132] Determining whether the first human body information is lower than a second distance threshold;

[0133] If yes, the first speed adjustment amount set by sending the second communication instruction information is set to zero.

[0134] It should be noted that when the measured first human body information is lower than the preset second distance threshold, it indicates that the user is too close to the hatch, and the remaining space is insufficient for the hatch to perform the opening or closing operation. At this time, the rotation state of the hatch motor is stopped, and the user is prompted through the buzzer or indicator light.

[0135] In the embodiments of the present application, further comprising:

[0136] Obtaining the first communication information;

[0137] Determining whether the first communication information is a first remote instruction;

[0138] If yes, the first remote instruction is parsed, and the opening or closing operation of the hatch is performed.

[0139] It should be noted that when the communication information on the bus is identified as the first remote instruction of the remote communication module, the operation code in the instruction is obtained according to the preset parsing method, and then the opening or closing operation of the hatch is performed according to the operation code, realizing the function of remote control.

[0140] It is worth mentioning that further comprising:

[0141] acquiring the first communication information;

[0142] judging whether the first communication information is a first height setting instruction;

[0143] if yes, analyzing the first height setting instruction to obtain third height information;

[0144] recording and storing the third height information.

[0145] It should be noted that the present application is provided with a hatch height memory function, that is, the height of the hatch opening is set according to the user's use requirements, and when the hatch is set to open, it stops at the set height, improving the user's experience. By analyzing the first height setting instruction, the third height information is obtained; wherein the third height information is the level of the height of the hatch set by the user, for example, level 1 represents 10 cm, level 2 represents 20 cm, and so on. The processor stores the third height information for the default height of the hatch opening.

[0146] It is worth mentioning that it also includes:

[0147] a man-machine interaction unit, at least including a buzzer, an indicator light;

[0148] During the hatch closing process, the indicator light is in a first indication state;

[0149] During the hatch opening process, the indicator light is in a second indication state;

[0150] When the anti-pinch function is triggered, the buzzer is in a first warning state.

[0151] It should be noted that by setting the buzzer, indicator light or display screen as a man-machine interaction unit, visual or audible prompts are provided for the user. For example, when the hatch is in the closing process, the indicator light is in a fast flashing state; when the hatch is in the opening process, the indicator light is in a constant state; when the anti-pinch function is triggered, the buzzer emits an alarm sound. Through the man-machine interaction unit, the user's experience is improved.

[0152] It is worth mentioning that it also includes:

[0153] During the hatch closing process, the second height information is acquired;

[0154] judging whether the second height information is zero;

[0155] if yes, starting the lock-down motor.
