The invention relates to an automatic train approach alarm device. The device is characterized by comprising an acquisition unit, a processing unit and an alarm unit, wherein the acquisition unit is used for acquiring train wheel passing signals and transmitting the acquired signal to the processing unit; the processing unit is used for processing the wheel passing signals, and if a plurality of wheels pass through a monitoring point in sequence, triggering the alarm unit to send out alarm information; the acquisition unit is electrically connected with the processing unit through an electriccable, and the processing unit is electrically connected with the alarm unit through an electric cable. When a train pulls in the station, the wheels pass through two electromagnetic sensors in sequence to trigger an alarm. All the parts are connected through common wires, signal interference is avoided while the cost is greatly reduced, and better communication quality and a stable working stateare obtained. The automatic train approach alarm device is easy to purchase, low in price and low in installation cost, can realize full-automatic control, and does not need to be operated by personnel; the overall power consumption is low, and the cost is greatly reduced.
本发明设计的列车接近自动报警装置,其特征在于:包括采集单元、处理单元和报警单元;采集单元,用于采集列车车轮经过信号并将采集到的信号传输给处理单元;处理单元,用于对所述车轮经过信号进行处理,有多个车轮先后经过监测点,触发报警单元发出报警信息;采集单元通过电线缆与处理单元电连接,处理单元通过电线缆与报警单元电连接。火车进站,车轮按照先后经过两个电磁传感器,触发报警;各部分之间采用的是普通电线连接,大大降低了成本的同时也避免了信号干扰,获得了更好的通讯质量和稳定的工作状态;本元器件容易购买且价格便宜,安装成本低,可以实现全自动控制,无需人员操作;整体功耗低,大大的降低了成本。
