The paper presented the working principle of a remote data acquisition system based on singlechip microcomputer and analyzed the system's failure modes. Fault tree analysis was used for establishing the system simulation model, and the Monte Carlo method was used for reliability simulation. The system reliability, MTBF, mode importance of basic components, etc. were obtained. Based on the result mentioned above, the system failure condition was analyzed, The conclusions provided a reference for reliability, maintainability and maintenance strategies of remote data acquisition system.
