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 railway workers to evacuate from an activity site by generating sound and vibration; and therefore, the purpose of protecting the safety of railway workers is achieved, and accidents are prevented.

    发明提供一种铁路报警装置,包括控制装置、信号检测器、接收端,所述信号检测器、接收端分别和控制装置连接;本发明为一种全新的安全、稳定、便携的报警装置,该产品基于4G通信技术和GPS定位系统所开发,其原理是通过在轨道上安装好的信号检测器实时检测火车位置信息,在检测到火车距接收装置4.6KM时,会对报警器发射信号,经过数据处理,通过STM32单片机和串口与GPS模块进行通信,通过4G将数据上传到云上,收集位置信息,控制装置通过LoRa模块与单片机实现预警然后将信号传送给接收装置,接收装置中的振动器、蜂鸣器通过产生声音和振动提醒铁路工作者撤离活动现场,从而达到保护铁路工作者安全的目的,防止意外事件发生。
