The invention relates to the technical field of railway traffic safety, and discloses a railway train coming early warning system and method based on a Lora communication technology. Comprising a LoRa data transmission radio transmitter mounted at the head of a train, a LoRa data transmission radio receiver mounted along a railway, an audible and visual alarm and a power supply system, wherein the LoRa data transmission radio transmitter transmits switching value signals according to a set period; the LoRa data radio receiver receives the switching value signal transmitted by the transmitter and judges whether the train enters an early warning area or not according to the strength of the received signal; the audible and visual alarm is controlled by the receiver to be started and sends out sound and light alarm signals. The power supply system is a solar power supply system. By adopting the railway coming train early warning system based on the LoRa communication technology and combining the flexible parameter adjustment of the transmitter and the receiver, the accurate control of the early warning range is realized. Reliable communication can be realized in a range of 800 meters by adjusting key parameters such as transmitting power and a signal threshold value.

    本申请涉及铁路交通安全技术领域,公开了一种基于Lora通讯技术的铁路来车预警系统及方法,包括安装于列车头部的LoRa数传电台发射器、安装于铁路沿线的LoRa数传电台接收器、声光报警器和供电系统:所述LoRa数传电台发射器按照设定的周期发射开关量信号;所述LoRa数传电台接收器接收所述发射器发射的开关量信号,并根据接收信号的强度判断列车是否进入预警区域;所述声光报警器由接收器控制启动,发出声音和灯光报警信号;所述供电系统为太阳能供电系统。通过采用基于LoRa通信技术的铁路来车预警系统,结合发射器和接收器的灵活参数调节,实现了预警范围的精准控制。通过调整发射功率、信号阈值等关键参数,能够在800米范围内实现可靠通信。
