摘要
传统的故障修复方法已经无法满足现代城市复杂的交通信息采集系统的需求,由于技术的不成熟性,导致大量信息数据的丢失,而且还存在故障排查的不准确性与低效性等问题。为此,提出城市交通信息采集系统故障诊断技术研究。首先对设备本身和系统本身出现的故障性分析构建出了诊断技术的硬件框图;然后根据诊断软件的流程图以及故障诊断的可信度函数对系统的软件保障进行了分析;最后对信息采集系统的故障诊断技术的可信度为实验目的进行了探究。实验结果证明,城市交通信息采集系统的故障诊断技术的设计非常的合理,能够利用系统分解的方法将繁琐的信息问题分解成若干个相对简单的信息单元,从而高效合理的诊断故障发生的原因,该技术会为交通的日常维护以及设备管理等方面带来巨大的效益。
Traditional fault repair methods have been unable to meet the demand of the modern urban complex traffic information collection system,as a result of the technology is not maturity,lead to the loss of a large number of information data,but also the existence of inaccuracy and inefficiency of troubleshooting problems. This paper puts forward the research on the fault diagnosis of urban traffic information acquisition system. First,the hardware block diagram of the diagnostic technology was constructed by the fault analysis of the device itself and the system itself. Then the software assurance of the system was analyzed according to the flowchart of the diagnostic software and the reliability function of the fault diagnosis. Finally,the reliability of the fault diagnosis technique of the information acquisition system is studied. The experimental results show that the urban traffic information collection system of fault diagnosis technology of the design is very reasonable,can use the system decomposition methods will trival information problem is decomposed into several relatively simple information unit,thus effective reasonable diagnose the cause of the failure,the technology will be for the daily maintenance of transportation and equipment management bring great benefits.
