Train approach automatic alarm device

Abstract

The invention relates to an automatic train approach alarm device. The device is characterized by comprising an acquisition unit, a processing unit and an alarm unit, wherein the acquisition unit is used for acquiring train wheel passing signals and transmitting the acquired signal to the processing unit; the processing unit is used for processing the wheel passing signals, and if a plurality of wheels pass through a monitoring point in sequence, triggering the alarm unit to send out alarm information; the acquisition unit is electrically connected with the processing unit through an electriccable, and the processing unit is electrically connected with the alarm unit through an electric cable. When a train pulls in the station, the wheels pass through two electromagnetic sensors in sequence to trigger an alarm. All the parts are connected through common wires, signal interference is avoided while the cost is greatly reduced, and better communication quality and a stable working stateare obtained. The automatic train approach alarm device is easy to purchase, low in price and low in installation cost, can realize full-automatic control, and does not need to be operated by personnel; the overall power consumption is low, and the cost is greatly reduced.

Description

technical field [0001] The invention belongs to an alarm device, in particular to an automatic alarm for train approaching, which is used to send a train approaching alarm signal to railway construction personnel when the train is approaching a construction site with personnel, prompting personnel to avoid and protect personnel's personal safety device. Background technique [0002] There are many train maintenance departments under the Railway Bureau, and the staff need to have "intimate" contact with the trains in the section, which has become a common practice. Every day, the train roars and the trains come and go. Anyone who understands this work knows that the personal safety and security of workers along the railway line is a very important issue. The normal regulation is: before the train enters the station, the train dispatcher in the station will report to the superior that there is a train that needs to enter the station, and after the superior’s approval, notify ...

AI Technical Summary

Problems solved by technology

The problem with this method is that the notifiers are labor-intensive and inefficient, and the quality of notifications cannot be guaranteed. The requirements for the number of notifiers and their sense of responsibility are relatively high.

Therefore, their specific implementation has brought serious problems of high cost, and various communication networks and modules need to be established to maintain operation

And inside the train and steel frame workshop, the wireless network cannot work well due to electrostatic shielding, and cannot transmit the train incoming signal stably.
