The On-line Monitoring Program Design Of Catenary Safe Operation

With the development of China 's high-speed rail and monitoring technology,railway catenary system monitoring technology put forward higher requirements.In order to achieve real-time,efficient and accurate requirements in terms of performance monitoring technology,the need to constantly improve monitoring technology,and the development of new means of monitoring the catenary.In the process of development of new means of surveillance technology,scientific,rational,executable plan is essential.After completion of the scientific program is designed to complete the various monitoring tools,monitoring aspects were fully rational argument.It is also necessary to analyze the results to the design,verification,in order to achieve the ultimate forrmally put into production use.Currently,catenary security status monitoring methods focus on the cycle detection,sentinel surveillance,data collection and transmission.However,since the monitoring data acquisition and transmission through the cable,with the result that a complicated wiring,easy to broken,resulting in data loss,which affect the reliability of the data collected.Therefore,this article in full consideration of the control measures,it is also proposed to implement a wireless network using GPRS monitoring data collection and transmission,thus improving the monitoring efficiency.In the analysis of domestic and foreign catenary monitoring of various geometric parameters,the tension monitoring occupies an important position,the paper compares several monitoring solutions,full consideration of the prior art,catenary trail design features,on this basis,constructed on the corresponding model.Meanwhile,the paper proposes a"three-point bending method" tension monitoring program,and made use of data transmission with the wireless transmission module for embedded systems.Finally,given the amount of data catenary monitoring system is complex,and more features,so the use of the C/S three-tier structure of the database in the database design to be addressed.By studying the entire program,in theory,be able to obtain more reliable results.
