The invention relates to the field of railway signal equipment control circuits. A crossing alarm system comprises a computer, a relay, an audible and visual alarm, a first track circuit, a second track circuit, a first annunciator, a second annunciator and a rectifier transformer, the first track circuit and the first annunciator are arranged on the side, where vehicles enter, of a crossing, and the second track circuit and the second annunciator are arranged on the side, where vehicles exit, of the crossing. The first track circuit, the second track circuit, the first annunciator and the second annunciator are electrically connected with a computer, the computer is electrically connected with a relay, the relay is electrically connected with a rectifier transformer, and the rectifier transformer is electrically connected with an audible and visual alarm. When a locomotive train passes through a crossing, the control system can automatically provide low-power sound-light alarm information, the automatic alarm system is different from a traditional automatic alarm system, an alarm horn and a lamp panel are not arranged on site, noise pollution does not exist, and safety of railway transportation operation is ensured.
本发明涉及铁路信号设备控制电路领域。一种道口报警系统,包括计算机、继电器、声光报警器、第一轨道电路、第二轨道电路、第一信号机、第二信号机、整流变压器,在道口进车辆的一侧设置有第一轨道电路和第一信号机,在道口出车辆的一侧设置有第二轨道电路和第二信号机,第一轨道电路、第二轨道电路、第一信号机和第二信号机均电连接计算机,计算机电连接继电器,继电器电连接整流变压器,整流变压器电连接声光报警器。本发明当机车车列通过道口时能自动提供小功率声光报警信息的控制系统:该自动报警系统与传统的自动报警系统有所不同,现场不设报警喇叭和灯盘,不存在噪音污染,确保了铁路运输作业安全。
