上海超声波仪器厂研制的CHB-1型双通道超声波行车避碰仪,可安装在行车上,用于监视行车行进方向上的障碍物,特别适用于在同一轨道上装有多台行车的场合。行车驾驶员可根据仪器上的距离数字显示和声光报警指示,随时了解行车行进过程中的情况。在设定的监视距离区内,除给出距离读数之外,尚有单音断续声响指示和绿灯断续闪光指示,以提醒驾驶员注意安全。在设定的制动距离区内,声指示信号变换为双音断续声响指示,光指示信号变为红灯和绿灯同时断续闪光指示。与此同时,仪器尚可输出一个制动信号,可使行车断电停车,避免行车相互碰撞而造成的重大事故。
CHB-1-type dual-channel ultrasonic collision avoidance instrument developed by Shanghai Ultrasonic Instrument Factory can be installed on the vehicle for monitoring the obstacles in the traveling direction of the vehicle. It is especially suitable for the occasions when multiple vehicles are installed on the same track. The driver can according to the distance on the instrument digital display and sound and light alarm instructions, keep abreast of the traffic in the process of the situation. In the set monitoring distance zone, in addition to distance readings, there are single-tone intermittent sound indicator and intermittent flashing green indicator to remind the driver to pay attention to safety. Within the set braking distance zone, the sound indication signal is transformed into a two-tone intermittent sound indication, and the light indication signal is changed into a red light and a green light, meanwhile, the intermittent flash indication is provided. At the same time, the instrument can still output a brake signal, can stop the car power off, avoid collision caused by driving a major accident.
