摘　　要：介绍了基于冗余容错技术的铁道罐车液位、温度和压力的测量系统,提出了基于三模冗余容错技术的数据采集技术,并通过马尔可夫分析方法对数据采集系统的可靠性和安全性进行了分析。结果表明,采用冗余容错技术能够提高系统的可靠性和安全性。The measurement system for liquid level, temperature and pressure of railway tank cars based on the redundancy fault tolerant technique is described. The data collection technology based on the triple module redundancy fault tolerant technique is put forward. The reliability and safety of the data collection system are analyzed through the Markov analysis method. The result shows that the reliability and safety of the system can be improved with the redundancy fault tolerant technique.
