Abstract

The invention discloses a wireless device used for detecting approaching of a train. The wireless device comprises a sensor module, a rectification and voltage increasing module, a voltage stabilizingmodule, an energy storage module, an impedance transformer module, a programmable amplifier module, a signal processing module, a microcontroller module and a radio frequency module, wherein the sensor module is used for converting deformation generated from joints of adjacent railways into an alternating current low-voltage electrical signal when the train approaches, and the rectification and voltage increasing module is used for converting the alternating current low-voltage electrical signal generated from the sensor module into a direct current low-voltage electrical signal, conducting voltage increasing treatment on the direct current low-voltage electrical signal to obtain a direct current electrical signal after voltage increasing, and transmitting one branch direct current electrical signal after voltage increasing to the voltage stabilizing module and the other branch direct current electrical signal after voltage increasing to the impedance transformer module. The device can solve the technical problems that an existing detecting device for approaching of the train needs the operation of wire routing and burying, so that the construction workload is large, and when faults occur, self-inspection cannot be conducted so that railway safety accidents can be easily caused.

Description

technical field [0001] The invention belongs to the technical field of railway operation safety, and more particularly relates to a wireless device for detecting approaching trains and a working method thereof. Background technique [0002] With the rapid development of the current railway information construction, the train approaching alarm system is widely used in the railway operation protection, which uses the train approaching detection device (such as magnetic steel sensor) to detect whether the train is coming, so as to remind the staff on the railway site Pay attention to avoiding, so as to avoid the occurrence of train accidents. [0003] However, there are some technical problems that cannot be ignored in the existing train approaching detection devices: first, the train approaching detection device and the train approaching alarm system are usually connected by wires, and wires need to be routed and buried at the construction site, and the construction volume is ...
