Monitoring and early warning system of railway train and construction maintenance

Abstract

The invention relates to the technical field of automatic control systems of transportation railway signals, in particular to a monitoring and early warning system of a railway train and construction maintenance on the basis of a technology of Internet of Things. The monitoring and early warning system is characterized in that the monitoring and early warning system comprises mobile hand-held terminals which are provided for on-road construction machines, protectors, maintainers and constructors, the mobile hand-held terminals conduct positioning through beidou satellites, position information is transmitted to a railway geographical information system (GIS) data server of a construction maintenance command center through a communication server GSM-R, and data of the railway GIS data server are called by an application server at the construction maintenance command center to be analyzed; and the hand-held terminals of the on-road construction machines, the protectors and monitoring personnel are matched with each other, ineffective protection early warning is started when the effective protection distance is exceeded, and displaying is simultaneously conducted on display terminals of all the terminals through acoustic-optical signals. The monitoring and early warning system is safe and stable, ensures that the train normally operates and enables safety protection on construction of existing lines to be more scientific and more effective.

Description

technical field [0001] The invention relates to the technical field of automatic railway signal control systems for transportation, in particular to a monitoring and early warning system for railway trains and construction maintenance based on Internet of Things technology. Background technique [0002] my country's railways generally rely on low-cost GPS in the fields of train positioning, geological disasters along the railway and infrastructure monitoring, engineering construction, etc., products involving satellite navigation application technology. However, the ownership, control, and operation rights of the GPS system belong to the US Department of Defense, which has problems such as artificial interference and signal instability. At present, the railway system is discussing the application of Beidou satellite navigation system, so as to comprehensively improve the safety and reliability of the railway system. sex. Compared with the GPS system, the advantage of the Be...

AI Technical Summary

Problems solved by technology

However, based on the Beidou satellite navigation system, the monitoring and early warning system that provides comprehensive technical support and supporting solutions for the railway industry is still technically blank.

The existing monitoring and early warning system for railway trains and construction maintenance is constantly increasing with the speed of existing lines, the increasing density of traffic, and the increasing instability of equipment status, resulting in a sharp increase in the workload of construction and maintenance of various existing lines. What has brought about is that the safety hazards of our current construction protection system mainly controlled by people are becoming increasingly prominent; in the process of construction and maintenance of existing lines, the current safety protection system is only provided by safety protection personnel, and there is no good technical means To ensure that the maintenance personnel, construction personnel, protection personnel, construction equipment and running trains are outside the safe protection distance, and the on-duty leader cannot accurately and timely obtain the location information of maintenance personnel, construction personnel, protection personnel, and construction equipment. and keep a safe distance between them
