Emitter of trackside environmental perception, collector of trackside environmental perception, receiver of trackside environmental perception and communication sensory perceptual system of trackside environmental perception

Abstract

The invention relates to an emitter of trackside environmental perception. The emitter of trackside environmental perception comprises a first serial-parallel conversion module, a constellation mapping module, a discrete fractional order inverse Fourier transform module, a first parallel-serial conversion module, a first digital-to-analogue conversion module and a first emitting module. Accordingto the emitter of the trackside environmental perception, a collector of the trackside environmental perception, a receiver of the trackside environmental perception and a communication sensory perceptual system of the trackside environmental perception, communication data is processed through the emitter, and a communication and radar integrated signal with communication and radar perception functions is generated. Trackside environmental parameters can be collected through the collector, an echo signal and the communication and radar integrated signal sent by other emitters can be received through the receiver, in addition, the receiver further can receive the trackside environmental parameters obtained by the collector, namely, whether a track is safe or not is judged further through radar perception and sensing perception while communication is met. According to the emitter of the trackside environmental perception, the collector of the trackside environmental perception, the receiver of the trackside environmental perception and the communication sensory perceptual system of the trackside environmental perception, the collection speed is high, detection dead zones are removed,the building cost is greatly reduced, and safety level of a track traffic system is improved.

Description

technical field [0001] The invention belongs to the field of safe operation of track operation, and in particular relates to a trackside environment sensing transmitter, collector, receiver and communication sensing system. Background technique [0002] At present, with the rapid development of the global economy, transportation has become an important part of people's daily life. Rail transit plays a pivotal role in the transportation system with its advantages of safety, speed, accessibility and low pollution. The rapid development of rail transit has attracted the attention of government departments and many experts and scholars. At present, the Chinese government has invested heavily in the construction of the rail transit system. As of 2017, the total mileage of my country's railway operations has exceeded 127,000 kilometers. With the continuous expansion of my country's railway operating mileage, the number of railway trackside infrastructure has also increased dram...

AI Technical Summary

Problems solved by technology

However, due to the long mileage and complex surrounding environment, rail transit will inevitably encounter safety problems caused by a series of natural disasters

However, the existing railway integrated video surveillance technology and other monitoring methods have great limitations in practical application due to problems such as detection blind spots, slow acquisition speed, and high cost.
