The RAMS Analysis On Computer Monitoring System And The Research Of Switch Acquisition

The paper expounds the background and the flame of computer monitoring system TJWX-2006,triumphantly programs the switch acquisition's software,and does the RAMS analysis on the TJWX-2006 computer monitoring system.The paper analyzes the hardware circuit based on LPC2292 microprocessor and CAN data packets,designs the software module.Finally the system accomplishes the data acquirement,processing and communication。The system was run at Chawu railway station in the course of nature,the capability of the TJWX-2000 of railway signal has been improved and finally used in Micro Union Co.Ltd..The paper also narrates the definition of RAMS,analyzes the meaning of RAMS on the new computer monitoring system TJWX-2006,compares and finally chooses FTA analysis to analyze the system on reliability,availability,maintainability and security first at home.After the RAMS analysis,the unsubstantial portion will be found. It can make us take actions to reduce the occurring probability of the fatal fault,and ensure the system's reliability,availability,maintainability and security.
