[0014] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0015] The present invention provides a vehicle-mounted multi-module integrated control system for controlling the air conditioner, heater, lighting and three-phase power supply module in the vehicle. Figure 1 As shown, it includes a power supply detection module, an integrated control module, a heating control module, a lighting control module and an air-conditioning control module, wherein the power supply detection module is connected to the three-phase power supply module for detecting power supply parameters; the integrated control module is connected to the power supply detection module for obtaining the detection result; and is also used to send control instructions; the heating control module is connected to the heater and the integrated control module for obtaining the status information of the heater, and updating the status variable of the heater according to the control instruction; the lighting control module is connected to the lighting lamp and the integrated control module for obtaining the working status of the lighting switch, and updating the status variable of the lighting switch according to the control instruction; the air-conditioning control module is connected to the air-conditioning and the integrated control module for obtaining the status information of the air-conditioning, and controlling the working mode and working parameters of the air-conditioning according to the control instruction.

[0016] In this embodiment, the power supply parameters are detected by the power supply detection module, and the heater, lighting and air conditioning are controlled accordingly by the heating control module, lighting control module and air-conditioning control module respectively, and each module is integrated and controlled by the integrated control module. According to user needs, each function can be operated conveniently and quickly, reducing system complexity and cost and optimizing the utilization rate of the space in the vehicle.

[0017] like Figure 2 As shown, it also includes a power adapter module, the input end of which is connected to the three-phase power module, and the output end is connected to the heating control module, the lighting control module, the air conditioning control module and the integrated control module, which is used to convert the three-phase voltage into a 24V DC voltage.

[0018] It also includes an alarm module, which is connected to the integrated control module and is used to issue an alarm when a control instruction indicating an abnormal detection result is received.

[0019] Furthermore, the heating control module connects the heater and the integrated control module through a bidirectional CAN bus. The integrated control module sends control instructions on the working status of the heater to the heating control module through the CAN bus. At the same time, the heating control module continuously receives status information of the heater through the CAN bus. The heating control module listens to the control commands from the integrated control module on the CAN bus data and updates the status variables of the heater.

[0020] The lighting control module connects the lighting lamp and the integrated control module through a bidirectional CAN bus. The integrated control module sends control instructions on the working status of the lighting switch to the lighting control module through the CAN bus. At the same time, the lighting control module periodically receives the current status information of the lighting switch through the CAN bus, where the cycle is 1s; the lighting control module listens to the control commands from the integrated control module on the CAN bus data and updates the lighting switch status variables.

[0021] The air conditioning control module connects the air conditioning and the integrated control module via a bidirectional CAN bus; the integrated control module connects the power supply detection module via a unidirectional CAN bus. The air conditioning device is used to adjust the temperature in the cabin, and maintains a certain temperature, humidity, flow rate, cleanliness and freshness of the air in the cabin through the refrigeration (heat) circulation system and the air circulation ventilation system. The air conditioning control module communicates with the integrated control module via a bidirectional CAN bus. The integrated control module sends control instructions to the air conditioning control module, controls the working mode and working parameters of the air conditioning through the air conditioning control module, and receives the status information of the air conditioning obtained by the air conditioning control module. The integrated control module is connected to the power supply detection module via a unidirectional CAN bus, and the power supply detection module sends the detection results to the integrated control module.

[0022] Further, such as Figure 3 As shown, the integrated control module includes a control module and a display module. The control module is connected to the heating control module, the lighting control module, the air-conditioning control module and the power supply detection module, and is used to send control instructions to the heating control module, the lighting control module and the air-conditioning control module respectively, and store the information to be displayed respectively. The information to be displayed includes the status information of the heater, the working status of the lighting switch, the status information of the air-conditioning and the detection results of the power supply parameters; the display module is connected to the control module to display the information to be displayed respectively.

[0023] The method for the control module to store the status information of the heater, the working status of the lighting switch, and the status information of the air conditioner includes: adding corresponding page numbers to the information to be displayed, and storing the information to be displayed and the corresponding page numbers respectively.

[0024] The method for the display module to display information includes: acquiring the information to be displayed, identifying the page number of the information to be displayed, and displaying the information to be displayed according to the page number.

[0025] Specifically, the control module receives data from the CAN bus, matches the data with the heating control module, lighting control module, air conditioning control module and power supply detection module according to the extended frame ID, stores the correctly matched data in the receiving structure, and sends the array storing the information to be displayed to the display module through the serial port. The display module determines the page number according to the sent data, and displays the parameters of each module at a fixed position on the display screen according to different page numbers. Exemplarily, the display module includes 4 display interfaces, namely the welcome interface, the three-phase power detection interface, the air conditioning control interface, and the heater control interface, and the corresponding page numbers are 0 to 3.

[0026] Among them, the three-phase power detection interface displays the detection results of power supply parameters and the working status of the lighting switch. The detection results include the current A-phase voltage, B-phase voltage, C-phase voltage, A-phase current, B-phase current, C-phase current, frequency, phase, and the abnormal state and online and offline state of the three-phase power detection module. The abnormal state includes normal, phase loss, undervoltage, and overvoltage. The lighting switch display bar displays the offline, on, and off states of the lighting in real time.

[0027] In this embodiment, the control instructions are issued and switched by means of buttons and knobs. The control module confirms the display interface according to the knob position. The welcome interface is entered by default when the power is turned on. After the software is normally started, it stays on the welcome interface for 2 seconds. After the 2s timing is over, it enters the normal knob switching interface state, and the current display interface is switched by rotating the knob. Through the buttons and knobs on the panel, good human-computer interaction can be achieved, and the working status of each functional module can be accurately controlled. For vehicle-mounted devices, the mechanical structure of the buttons and knobs is more durable and reliable. The timing unit of the system of the present invention is 1ms, the real-time performance is high, and the system response is more sensitive. The vehicle-mounted multi-module integrated control system reserves a software update interface, including RS485 and RS232 communication expansion interfaces, which provides sufficient space for later equipment updates and upgrades.

[0028] For example, Figure 4 As shown, the panel of the control module includes a page switching knob 1, a button 2, a button 3, a button 4, a mounting hole 5, a panel 6, a display screen 7, a button 8, a button 9, a confirmation button 10, and a brightness adjustment knob 11. The buttons are distributed on the panel 6, and the left side is respectively button 2, button 3, and button 4 from top to bottom; the right side is respectively button 8, button 9, and confirmation button 10 from top to bottom. The page switching knob 1 is used to switch the screen of the display screen 7. The switching process is as follows Figure 5As shown. The brightness adjustment knob 11 is used to adjust the brightness of the display screen 7. Turning the brightness adjustment knob 11 rightward increases the screen brightness of the display screen 7, and turning it leftward decreases the screen brightness of the display screen 7. The system automatically enters the power supply detection interface 2 seconds after power-on. The power supply detection interface is used to receive the status information reported by the three-phase power detection module and the lighting control module and send control instructions to the lighting module through button 9 to control the working state of the lighting module. The received data of the three-phase power detection module include A-phase voltage, B-phase voltage, C-phase voltage, A-phase current, B-phase current, C-phase current, frequency, phase, abnormal state of the three-phase power detection module, and online and offline states. The data received from the lighting control module is online and offline states. In this interface, button 9 is mainly used to control the switch state of the lighting module. When button 9 is pressed, if the lighting module is in the on state, it is converted to the off state; if the lighting module is in the off state, it is converted to the on state. Rotate the page switch knob 1 to switch the page to the air conditioning control interface. The air conditioning control interface is used to receive the status information reported by the air conditioning, display the current working status of the air conditioning, and send control instructions to the air conditioning through buttons to control the working mode and working parameters of the air conditioning. The air conditioning data received include ambient humidity, ambient temperature, set temperature, working mode and fault code. In this interface, button 2 is used to switch the air conditioning on / off, button 3 is used to switch the return / fresh air, button 4 is used to switch the working mode, button 8 is used to increase the set temperature value, and button 9 is used to decrease the set temperature value. Continue to rotate the page switch knob 1 to the heater control interface. The heater control interface is used to receive the self-working status information reported by heater 1, heater 2, and heater 3 in a periodic manner, display the current working status, and send data instructions to control the working status of heater 1, heater 2, and heater 3 through buttons. The data received from heater 1, heater 2, and heater 3 include the power on / off status, mode, temperature, and gear. In this interface, button 4 is used to switch the working mode, button 8 is used to set the gear / temperature increase, and button 9 is used to set the gear / temperature decrease. The vehicle-mounted multi-module integrated control system is fixed in the central control assembly through the mounting hole 5.
