Research On Railway Freight Car Positioning And Alarm System Based On Beidou

As the logistics market is extremely saturated,railways,as an old-fashioned industry of freight transportation,have gradually fallen behind and the situation is not optimistic.Driven by the general environment,railway freight must accelerate the change of its own hardware level and service quality with the development of the times.In view of this,the derivative system of railway freight has come into being.The research and development of railway freight car positioning and alarm system is mainly used to improve the hardware system of railway freight service,so as to increase the railway’s market share in freight transportation.This article is mainly for the research on the railway freight car positioning and alarm system based on Beidou.First of all,this article analyzes the current development status of the logistics market,puts forward suggestions for improving railway freight hardware service standards,and improves railway freight cars and alarm systems.According to the current research status of map matching algorithms,it combines with railway freight cars real-time positioning,and Integrate the alarm system into it.Then the corresponding wireless communication technology was determined,and the research on the railway freight car positioning and alarm system based on Beidou has never been realized.Secondly,this article focuses on the design of Beidou vehicle terminal hardware system structure and the principle of Beidou positioning technology.According to the development of the current Beidou technology and the development requirements of the current Beidou freight technology,the hardware requirements for the Beidou positioning in the railway freight system are determined,and the core controller software is selected and designed,the serial communication interface module is designed,and the wireless communication transmitter is selected and designed.The design plan of the receiving organization.Subsequently,this article introduces the design of the railway freight car ground monitoring system.Based on the original method,the ground monitoring system is designed based on the operation mode of railway freight cars in the dispatch center.Taking the efficiency of railway freight car dispatching,freight car safety,and positioning accuracy as its implementation standards,a complete set of real-time monitoring information system for railway freight car operation has been built,covering railway freight car dispatching management interfaces,railway freight car real-time positioning information display interfaces,Finally,this article systematically summarizes the core technology of the railway freight car positioning and alarm system,and expounds the difficulties and solutions encountered in the research and development of this system.It also shows the shortcomings of the system and shows the broadness of the system.
