铁路道口过车检测装置设计

分析了铁路道口管理的需要，根据实际工作环境，采用铁路专用车轮传感器检测通过列车，并用无线传输技术，降低了施工难度，实现了道口的自动管理．当列车通过时，用语音提示过往行人和车辆注意安全，提示道口工作人员注意坚守岗位，避免了人工了望可能带来的失误．

Design of the train-detection device on the rail-highway grade crossing

This paper discussed the demand of the crossing watching. In the practical working circumstances, we have achieved the purpose of the automation in crossing watching with the help of the wheel sensor to detect the passing of train and radio transmission to reduce the construction difficulties. Using the audio device to send the voices recorded in advance, the device can warn the passengers and vehicles to stay away and call the watcher's attention to the watching to avoid the latent mistakes of manual operation when the train passes.
