[0013] To make the purpose, content and advantages of the present utility model clearer, the following further describes in detail the detailed implementation manners of the present utility model.

[0014] A control panel for a charging and discharging system of a special vehicle proposed by the present utility model includes a silent silicone microswitch button (1), a display screen (2), an acquisition main control board (3), a socket (4), a box body with a buckle (5), and a key indicator light (6);

[0015] The display screen (2) is a 1.54-inch OLED display screen.

[0016] The acquisition main control board (3) is arranged in the box body, and the silent silicone microswitch button (1), the display screen (2), and the key indicator light (6) are all arranged on one side of the box body to form a front panel component (7); the socket (4) is fixed on the box body;

[0017] The box body of the present utility model is directly fixed to the cab of the special vehicle through a drawer buckle, and the socket (4) is streamlined to only a four-core socket, and is connected to the vehicle cable through an external cable.

[0018] The control panel performs CAN communication with the in-vehicle vehicle bus to realize the control of functions such as main valve inflation, deflation, pressure holding, and tire pressure monitoring. The fault information of some sensors of the main valve and the high-side valve will also be mutually transmitted through the CAN bus and displayed on the OLED display screen.

[0019] The acquisition main control board (3) is used to communicate with the in-vehicle vehicle bus, collect key information, and drive the key indicator light (6) corresponding to the key; the acquisition main control board (3) can also collect sensor information and high-side valve fault information and make the OLED display screen display corresponding information through SPI bus communication.

[0020] The acquisition main control board adopts a CAN bus isolation chip and has 2-way CAN bus communication functions.

[0021] The acquisition main control board adopts an SPI bus isolation chip and has 1-way high-speed SPI bus communication functions.

[0022] The acquisition main control board uses a switch power supply with a wide voltage of 9 - 36V to convert the rough power into the system's refined power. With an RC filtering circuit, it can ensure that the ripple of the system's refined power is within 5‰.

[0023] The MCU processor of the acquisition main control board uses the ARM series STM32G474 and TM1638 to achieve key acquisition and drive of key indicator lights.

[0024] The specific implementation process is as follows:

[0025] 1. As Figure 1 shown, power on the control panel through the socket. After pressing the power button on the control panel, the backlight of the control panel lights up. When the corresponding function button is pressed and valid, the corresponding indicator light will light up, and similarly, it will go out correspondingly. And the command is sent to the socket through the CAN bus communication method, and each tire pressure data and main valve fault information of the underlying CAN bus will also be received, and finally, it will be intuitively displayed on the OLED display screen.

[0026] 2. As Figure 2 shown, call the key acquisition sub-module to determine whether the bridge values of keys 1 / 2 / 3 / 4 on the current panel are pressed and valid. If invalid, directly return to the key acquisition sub-module. If valid, determine whether the current working condition button is pressed and valid. If invalid, similarly, directly return to the key acquisition sub-module. If the key working condition value is valid, determine which working condition button is pressed currently. When the hold pressure (Main Press) button is pressed, call the hold pressure data processing sub-function. When the tire pressure detection (Detection) button is pressed, call the tire pressure detection data processing sub-function. The processing methods for other manual (Manuel) working condition buttons and automatic (Auto) working conditions (including: highway (Route), off-road (Tout-terain), gravel (Souplesse)) buttons are similar. Finally, call the CAN send sub-function to send the data to the bus through the socket (4).

[0027] 2.1. The hold pressure (Main Press) key is valid

[0028] As Figure 3 shown, determine whether the hold pressure key (Main Press) is valid. If invalid, directly return 0. If valid, organize and pack the data according to the corresponding protocol and return the data. Finally, the data will be sent to the bus through the socket by the CAN send sub-function.

[0029] 2.2. The tire pressure (Detection) detection key is valid

[0030] As Figure 4Tire pressure detection button working condition flow chart. Since the priority of pressure maintenance is the highest, it is necessary to determine whether the current pressure maintenance button is valid. If it is valid, return directly. If it is invalid, continue to determine whether the tire pressure detection button value is valid. If it is valid, clear the common command array, organize the data according to the protocol, and return the tire pressure detection data. If it is invalid, return 0 directly.

[0031] 2.3. The manual button is valid

[0032] As Figure 5 shown, first determine whether the pressure maintenance button and the tire pressure detection button are valid. If they are invalid, continue to determine whether the manual working condition button is pressed and valid. If it is valid, continue to determine whether the manual inflation or deflation button is valid. If it is valid, clear the common array, organize the data according to the protocol, and return the manual command data. If the pressure maintenance and tire pressure of the current working condition are valid, return 0 directly. In other cases, return 0 if invalid.

[0033] 2.4. The auto button is valid

[0034] As Figure 6 shown, similarly, it is necessary to determine whether the pressure maintenance button and the tire pressure detection button are valid. If they are invalid, continue to determine whether the highway button, off-road button or gravel button of the auto working condition is pressed and valid. If it is valid, clear the common array, organize the data according to the preset tire pressure value, and return the manual command data. Similarly, return 0 directly in other cases.

[0035] The utility model is specially designed for special vehicles and has the advantages of small structure, safety and reliability, simple installation, high integration, relatively low selling price, etc.

[0036] The control panel of this air charging and discharging system adopts highly integrated design. The button acquisition and indicator light driving are processed by an integrated chip, which reduces both cost and space, meets the requirements of the vehicle's overall high integration, informatization and intelligence. At the same time, the buttons on the panel adopt silent silicone micro-motion buttons, which improve the operation experience, enrich the button control functions and information display.

[0037] Make the structure of the entire air charging and discharging system control panel more compact, lighter in weight, reduce the socket cables, and greatly reduce the cost to meet the market demand.

[0038] The above are only the preferred embodiments of the utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the utility model.
