[0050] Examples:
[0051] Such as figure 1 The automatic sound and light alarm method for the railway level crossing shown is as follows:
[0052] 1. The proximity sensor units 101 and 102 are arranged in pairs on the railway lines on both sides of the railway level crossing. The two pressure sensors arranged at intervals under the rails respectively detect that the train has passed through, and then pass the signal of the corresponding proximity sensor unit The transmitter wirelessly transmits the detection signal and the signal time to the signal receiving unit 2 at the crossing; the departure sensor unit 8 arranged at the other end of the crossing corresponding to the proximity sensor unit that has detected the approach of the train will change at a fixed time interval when detecting the passing of the train The sensor signal is sent to the signal receiving unit 2 of the crossing; the signal receiving unit 2 detects the signal in real time, and when it receives the signal sent ...
