Embodiment Construction

[0017] Figure 1 describes the control circuit installed in the control box and connected to the control buttons and display indicators on the panel shown in Figure 5 . The control circuit is electrically connected to the tire central inflation and deflation system composed of electricity, air source, control unit, execution unit wheel valve, lock valve and air circuit conversion unit.

[0018] In Figure 1 and Figure 2, the component at the core of the control circuit is a PIC microcontroller. The microcontroller can be, but not limited to, strong anti-interference ability, high internal integration, 8-way 12-bit AD conversion, I 2 C communication module, USART serial port communication module, PIC microcontroller with 4 groups of 8-bit standard bidirectional ports. For example, choose the PIC16 series single-chip microcomputer of MICROCHIP Company. Selecting PIC16 series single-chip microcomputer can not only greatly simplify the peripheral circuit and improve the reliabilit...

Abstract

The air charging control box in the middle of the vehicle tier to regulate the inner pressure of the cross country vehicle and military vehicle, comprises a control panel with electric control circuit and an electric power, control unit, execution unit and air channel exchange unit control box. The control circuit is connected with the vibration circuit, road status display circuit, keyboard matrix circuit, current signal conversion voltage signal circuit, separation amplification circuit and data decoding, displacement, section addressing, single chip machine with LED drive circuit for warning, signaling, and circuit installation display circuit. It can precede automatic checking and regulation to the tire pressure inside the driving chamber, discharging manually or automatically, timely monitoring the pressure and warning of the display tire. It is optional based on the different requirement of the driver.

Description

technical field [0001] The invention relates to a control device which is installed in the cab of a wheeled vehicle tire central inflation and deflation system to conveniently detect and adjust the tire pressure of the whole vehicle and control tire inflation and deflation. In particular, electronic controllers that can easily adjust the pressure inside the tires of central inflation and deflation control systems running on off-road vehicles and military vehicles. Background technique [0002] Vehicles in war or traveling often need to drive off-road on farmland or muddy ground. If the car is running with normal tire pressure, it will get stuck or skid. Many modern weapons such as missiles, artillery, etc. are mounted on wheeled vehicles. When the tire inner tube is punctured or pierced by bullets and leaks air; All may cause the tire to burst or leak, and the situation that cannot be exercised occurs. In order to improve the maneuverability and survivability of vehicle-m...
