The invention relates to a rail transit early warning device. The rail transit early warning device comprises a controller, infrared signal transmitters, infrared signal receivers, a network relay, acommunication transmission assembly and an alarm assembly, wherein the infrared signal transmitters and the infrared signal receivers are arranged at the positions, away from a railway crossing by a preset distance, of a rail in pairs, the infrared signal transmitters and the infrared signal receivers are arranged on the two sides of the rail respectively, the infrared signal transmitters are usedfor transmitting infrared signals, and the infrared signal receivers are used for receiving the infrared signals; when the infrared signal receivers do not receive the infrared signal, the infrared signal receivers generate an early warning signal, the early warning signal triggers the network relay to be conducted, and the early warning signal is transmitted to the control module through the communication transmission assembly; and after receiving the early warning signal, the control module sends an alarm instruction to the alarm assembly, so that the alarm assembly sends an alarm prompt, and the timeliness of early warning message sending is ensured.
本发明涉及一种轨道交通预警装置,包括:控制器、红外信号发射器、红外信号接收器、网络继电器、通信传输组件和报警组件;红外信号发射器和红外信号接收器成对设置于距离铁路道口预设距离的铁轨处,红外信号发射器和红外信号接收器分别设置于铁轨的两侧,红外信号发射器用于发射红外信号,红外信号接收器用于接收红外信号;当红外信号接收器未接收到红外信号时,红外信号接收器产生预警信号,预警信号触发网络继电器导通,预警信号经通信传输组件传输至控制模块;控制模块接收到预警信号后,发出报警指令至报警组件,以使报警组件发出报警提示,进而保证预警消息发送的及时性。
