Safety braking system (TY-ASD) control principle ---- air brake dual braking system

Through the safety and reliability performance technical evaluation of the Computer and Microelectronics Development Research Center of the Ministry of Industry and Information Technology, the safety and reliability meet the requirements of use

The 3D sensor collects the distance information of obstacles in the front and lower height range of 4m, and the width of 1.5m. The detection laser beam is 1024, and any laser can measure the distance, and calculate the nearest distance at a speed of 0.1S and make processing. It is fearless of extreme weather such as sand, snow, rain, fog and thunder, and realize the global coverage of civil aviation equipment

When the distance from the aircraft is 2 meters ≤5 meters, the control speed is 2Km/h. When the distance from the aircraft is 0.3 meters ≤2 meters, the control speed is 0.7km/h. When the distance from the aircraft is 0.3 meters, the brake can be stopped at 0.1 meters

The speed information is read from the vehicle transmission and ABS controller through the bus, and the control software realizes the logical control of the vehicle system according to the speed signal and a large amount of distance information collected from the 3D sensor. At the same time, the electrical signal output by the controller can control the brake pressure through the solenoid valve, thus playing the braking role and controlling the speed. The display displays speed, distance and warning information

The system uses 3D sensors to detect the position of the cabin door, collect the speed signal and the throttle signal for logic control, and realize the control of overspeed warning, alarm, throttle speed limit and automatic braking through professional control software.
