The Design Of Locomotive Monitoring And Controlling Device Based On ARM Platform

The safety of running train is becoming more and more important as the development of railway. The Locomotive Monitoring and Controlling Device is an monitoring and controlling device which is designed after analyzed the condition of railway device and actual requirement of our country, the purpose of design is to make sure the safety of railway transportation.The paper use ARM-uClinux as the system platform, this embedded system could be make used to special condition, and it's hardware or software could be modify and they are simple, the requirement of real-time could be satisfied by them.About the hardware design, paper make a description of monitor and recording section, the circuit of analog data I/O,digital data input, digital data I/O sampling, communication, the main power supply and the overpressure restrains board.About the software design,The page first describe the build of the crossing compile environment and the transplant of the uClinux operating system. Then the article describe the software design of the running control process which including the speed judgement and the dispose of train light signal.Finally,the page give the design of GPRS wireless communication programme and Human-computer interaction interface.Based on my study,this project have a great meaning in the safty of railway traffic,and worth continuing study.
