Railway alarm device

The invention provides a railway alarm device which comprises a control device, a signal detector and a receiving end, and the signal detector and the receiving end are respectively connected with thecontrol device. The railway distance alarm device is a brand-new safe, stable and portable alarm device, is developed based on the 4G communication technology and a GPS positioning system, and has the principle that train position information is detected in real time through the signal detector installed on a track, when 4.6 KM of a train distance receiving device is detected, a signal is transmitted to the alarm device, after data processing, an STM32 single-chip microcomputer and a serial port communicate with a GPS module, data are uploaded to the cloud through 4G, the position informationis collected, the control device achieves early warning through a LoRa module and the single-chip microcomputer and then transmits signals to a receiving device, and a vibrator and a buzzer in the receiving device remind rail
