Train incoming early warning device and method

Abstract

The invention discloses a train incoming early warning device and method, and belongs to the field of train arrival early warning. The train incoming early warning device comprises a train detection device and a combined aural and visual alarm, wherein the train detection device is arranged on the lateral side of a to-be-detected track, the combined aural and visual alarm is arranged at a construction position, and the distance from the combined aural and visual alarm to the train detection device is 2-3 kilometers. The train incoming early warning device comprises a shell, and a magnetic induction module, a data processing module and a wireless sending module are arranged in the shell; a photoelectric sensing module is arranged on the upper portion of the outer portion of the shell, the photoelectric sensing module comprises two photoelectric sensors, the magnetic induction module and the photoelectric sensing module are connected to an input end of the data processing module, and theoutput end of the data processing module is connected to the wireless sending module. The combined aural and visual alarm comprises a wireless receiving module and an alarm module which is connectedwith the wireless receiving module; the wireless sending module and the wireless receiving module are 433 wireless modules. The device is low in false alarm rate, remote information transfer can be achieved, and the train running direction can be detected.

Description

Technical field [0001] The present invention relates to the technical field of train arrival early warning, in particular to a train arrival early warning device and method. Background technique [0002] Tracks, foundations, signal equipment, pipelines, etc. on the railway require frequent maintenance. There is a great danger in the maintenance work on the railway. There are often accidents where railway maintenance personnel are hit by passing trains or even killed. At present, there are many trains on the railway, and they are fast, especially on high-speed railway lines. The general situation of comprehensive train speed increase has taken shape, which puts forward higher requirements on the early warning system to protect the personal safety of personnel along the railway. However, most of the current early warning methods used in practice use manual early warning, calculation time limit speed limit and other methods, which are not only inefficient, but also not highly relia...

AI Technical Summary

Problems solved by technology

However, most of the early warning methods currently used in practice use methods such as manual early warning, speed limit and time limit for calculation periods, which are not only inefficient, but also not highly reliable. It is urgent to design a new early warning system to solve this situation

[0003] The invention patent with the application number of 200910309382.5 discloses a vehicle detector for anti-false detection ring coil. The main principle of this patent is electromagnetic induction. The metal (such as underground manhole cover, etc.) and the particularity of some vehicles (such as the chassis height of the large vehicle, uneven iron material of the vehicle body, etc.), may cause system omission or false alarm

In addition, when there are many iron-containing substances near the detection device or on multiple parallel tracks, the possibility of false alarms by the system will increase; the detection device of this patent is placed on the track passing by the vehicle, and this arrangement will endanger Traffic safety, cannot be used for train approaching warning; train approaching warning device is generally used in train track construction, in order to ensure smooth construction, it should be ensured that the train going to the direction of the construction team alarms, and the train away from the direction of the construction team does not need to alarm, and The patent does not detect the direction of travel of the vehicle

[0004] The utility model patent with the application number 201220092252.8 discloses a train arrival warning system. The detection sensor of this patent is a three-axis acceleration sensor. When the train comes, it often involves many vibration sources, such as vibration caused by construction repairs or other These factors are likely to cause false alarms; the alarm information in this patent uses the zigbee communication protocol, which is a low-power personal area network protocol based on the IEEE802.15.4 standard, and is a short-distance, low-power Consumption of wireless communication technology, which is characterized by short-distance, self-organization, low power consumption, low data rate, low cost, obviously, can not meet the long-distance information transmission; moreover, this utility model can not detect the driving direction of the train
