Research on Remote Data Acquisition System Reliability Simulation

摘要

This paper presents the working principle of a remote data acquisition system based on SCM(single chip microcomputer) and analyzes the system's failure modes. It establishes the system simulation model by using fault tree analysis, and it uses Monte Carlo method to carry on reliability simulation. The total failure rate, MTBF, importance of each component and the system reliability distribution histogram are obtained. Based on the result mentioned above, we can find an effective way to improve system reliability.
