System Introduction

The auxiliary collision avoidance and end wall collision avoidance system is a set of collision risk monitoring and early warning equipment used between trains and between trains and end walls. It uses wireless radar ranging technology to detect the distance and speed between protective equipment in real time, and then evaluates the collision risk level in combination with the safe braking distance at the current speed of the train. According to the collision risk level, it takes measures such as buzzer warning and emergency braking to ensure the safe operation of the train and avoid collision risks.

System Features

1. Distance and speed measurement

1. The maximum detection distance of a straight road section can reach 1500 meters, the static distance measurement error is ±2 meters, and the speed measurement accuracy is ±3 kilometers per hour;

2. Early warning protection

It has a variety of risk treatment measures such as buzzer, brake signal and TCMS network, and can take a variety of treatment measures for different working conditions;

3. System self-test

The system can detect the status of the internal main control board and external sensors by polling, and can detect faults in time and record and save the fault status;

4. Data storage

It has a log record storage function, and the log content includes system status, alarm status, distance measurement value, brake status and other information.

System Features

1. SIL2 safety certification

2. Wireless communication frequency band complies with policies and regulations

3. Detection and protection of curves beyond the visual range

4. Long detection distance and high accuracy

5. Comply with rail transit standards
