该系统是防止大型矿用汽车与停放在汽车司机不易看到地点的小型车辆之间的碰撞。现研制了两种电子系统可用于检测已停放汽车的看不见处有无车辆。该系统可以警告汽车司机注意挡住其视野的车辆,但这种系统不适用运行的汽车。这两种系统都使用电子传输技术,一种是以低频无线电波为基础,另一种是以高频无线电波为基础。每一系统都需在检测的小型车辆上安装一台信号发射机。安装在大型运输汽车右前方和尾部的接收天线接收发射 The system prevents collisions between large mining vehicles and small vehicles parked in hard-to-reach spots for car drivers. Two types of electronic systems have been developed to detect the presence or absence of vehicles in the parked vehicles. The system can alert car drivers to vehicles that block their view, but such systems are not suitable for running cars. Both systems use electronic transmission technology, one based on low-frequency radio waves and the other on high-frequency radio waves. Each system requires the installation of a signal transmitter on a small vehicle under test. Receiving antennas mounted on the right front and rear of large transport vehicles receive the transmission
