OOB-1型超声测距报警器是根据脉冲雷达原理研制而成的,由传感器和信号处理机两部分所组成。使用本装置可以有效地防止同一跨度内相邻两部行车的碰撞。 传感器装在本行车上,向正前方发射超声波,并接收安装在相邻行车上反声板的回波。回波通过电缆送到放置于本行车驾驶室内的信号
OOB-1 ultrasonic ranging alarm is based on the principle of pulse radar developed by the sensor and signal processor composed of two parts. The device can effectively prevent the collision of two adjacent vehicles in the same span. The sensor is mounted on the vehicle, emitting the ultrasonic waves to the front and receiving the echoes of the anti-sound board mounted on the adjacent vehicle. The echo is sent by cable to the signal placed in the driver’s cab
