Railway foreign matter invasion detection and alarm device based on mesh sensor

Abstract

The railway foreign matter invasion detection and alarm device comprises a sensor module, a data communication module and a data processing and alarm center which are connected in sequence, the sensor module is arranged on the outer side of a railway, and the sensor module comprises a stand column, a net-shaped structure, a wire, a protection resistor, an address module and a power source. The net-shaped structure is supported by the stand columns, the wires are distributed in the horizontal direction of the net-shaped structure, and the wires, the protective resistor and the power supply are sequentially connected to form a loop. The address modules are connected in parallel to the two ends of the protective resistor, the wire is of a sectional structure, and every two adjacent wire sections are detachably connected through a connector clip; the data processing and alarming center reads output level data of each sensor module through the data communication module, and railway foreign matter invasion detection and alarming are achieved. Compared with the prior art, debris flow, landslide and rockfall invasion along the railway can be accurately monitored in real time, and safe operation of the railway is guaranteed.

Description

technical field [0001] The invention relates to the technical field of railway foreign object intrusion detection, in particular to a railway foreign object intrusion detection and alarm device based on a mesh sensor. Background technique [0002] Foreign matter intrusion is one of the main sources of emergencies in railways. Therefore, real-time and effective monitoring and early warning of foreign matter invasion is an important basis for ensuring the safety of train operation, improving emergency response capabilities, and ensuring efficient railway operation. [0003] There are two main manifestations of foreign matter invasion. First, non-living objects such as mudslides, landslides, and falling rocks, due to their size and falling speed, fail to fall into the drainage ditch built along the high-speed rail and invade the boundary. Second, living organisms such as wild animals, due to their daily activities, accidentally climb over and pass through the protective net an...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a railway foreign matter invasion detection and alarm device based on mesh sensors in order to overcome the defects of relying on cameras at both ends of the railway to manually identify foreign matter invasion, the method is inefficient, and the engineering cost is huge in order to overcome the defects of the above-mentioned prior art
