The Design And Implementation Of Embedded Detector In Locomotive Safety Monitoring Device

With the rapid development of the rail transport industry and the continuous improvement of the running speed of the train, the requirements of traffic safety equipments in the aspects of functionality, reliability and security are increasing, by passenger and cargo transport. At the same time, automotive systems information technology makes a collection of numerous safety information detection and data transmission equipments related to the locomotive running status, such as track dynamic testing equipment, the bow network detection equipment, voice recording equipment, train running information transmission equipment and so on.As the plugs in motorcycle safety information monitoring device, they are working at monitoring device platform. To ensure the environment of the platform to maintain the stability and reliability, can greatly improve the safety of the running trains.In order to make the platform operating normally for the safety information detection and data transmission equipments, to make sure the entire train running safety control system in well-functioning condition, this paper presents an idea to design a locomotive safety monitoring device embedded detector, the design of the detector uses online method to test monitoring device. With non-destructive detection for the variety of important performance data during the monitoring device working time, it can send the information to the terminal to display the test results at the real-time.This paper is based on the embedded ARM chip LPC2294as the core to design the hardware circuit of power module, voltage detection module, RS485communication module, CAN communication module, wireless communication module and so on. With handheld communication terminal, it developed monitoring device online detection software system and achieved functions of monitoring device voltage detection, monitoring information listening, RS485communication quality judgment, and forwarding the monitoring device status information.to the handheld communication terminal via wireless,ect. Locomotive safety monitoring devices embedded detector using PC software to detect monitoring device.The online detection could get the information about the working situation of monitoring device, while the communication data could be imported to the analysis software to establish the historical archives of the locomotive equipments running information, which can provide a scientific basis for the technical staff to identify hidden faults as soon as possible. The design and implementation of embedded detector has important practical significance to improve the stability and reliability of the information monitoring platform and early fault identification.
