Railway outdoor signal device monitoring system based on NBIoT (narrow band internet of things)

Abstract

The invention discloses a railway outdoor signal device monitoring system based on an NBIoT (narrow band internet of things). The system comprises a railway outdoor signal device data acquisition unit, a railway outdoor signal device monitoring management platform and a mobile terminal, a railway outdoor signal device mainly comprises a turnout switching device, a track circuit, a signal machine,a box and the like, and a railway signal is a general name of manual control, automatic control and remote control technologies for ensuring driving safety and improving passing capability and codingand decoding capability of sections and stations in a railway transportation system. By the aid of the NBIoT technologies which have the advantages of low power consumption and wide signal covering range, running states of railway outdoor signal devices such as the turnout switching device, the track circuit, the signal machine and the box affecting driving safety are monitored.

Description

technical field [0001] The invention relates to the technical field of railway signal equipment monitoring, in particular to a railway outdoor signal equipment monitoring system based on the NBIoT Internet of Things. Background technique [0002] With the rapid development of my country's railways, the requirements for the safe and efficient operation of railways are getting higher and higher. Railway signal equipment plays a very important role in the entire railway operation. A small fault may disrupt the traffic order and ensure safety. Not guaranteed. At present, the maintenance of railway signal equipment generally adopts the method of regular inspection and replacement, and the status during operation is unknown.

AI Technical Summary

Problems solved by technology

At present, the maintenance of railway signal equipment generally adopts the method of regular inspection and replacement, and the status during operation is unknown. The quality of operation of railway outdoor signal equipment directly affects the operation of trains, such as compensation capacitors in track circuits It is an important part of train information transmission, and because it is the most prone to deterioration and failure, and the number is large, it is difficult to find even if a fault occurs, which greatly reduces the efficiency of fault handling

At present, the capacitance measurement on the track circuit is measured manually with a special instrument on the track regularly, which not only affects the driving, but also is unsafe.

Another example is that if the gap width of the turnout switch machine is too large or too small, the switch machine cannot be locked, resulting in the failure of the switch to operate properly.

Another example is that the brightness of the signal light of the signal machine affects the driving problem, the humidity of the box affects the insulation problem, etc.

With the application of NBIoT Internet of Things technology, the mode of "regular inspection and replacement" can no longer adapt to the development requirements of the new situation. Therefore, it is imperative to develop a railway outdoor signal equipment monitoring system based on NBIoT Internet of Things
