Study on State Evaluation of Sensing Equipment in Expressway Network

该文结合实际运行经验,在公路网传感设备运行状态的评价过程中,将定性的评价结果用定量信息进行描述。应用模糊综合评判方法对传感设备的状态开展量化评估。在研究并选取状态特征参量的基础上,引入模糊数学理论,将状态参量信息通过模糊三角分布隶属函数来表示。实例证明,该方法在评价传感设备状态时,模糊三角分布隶属函数可以将设备状态特征信息和设备性能进行有效的关联,恰当地反映了设备当前的运行工况,较为符合传感设备运行状态变化规律。其评价结果可以为科学开展设备状态检修、风险评估等工作提供科学的依据。

Based on the practical operating experience in the evaluation of expressway network sensing equipment, this paper describes the qualitative evaluation results by the quantitative information, and introduces the quantization evaluation of the sensing equipment state by the fuzzy comprehensive evaluation method. On the basis of studying and selecting the state characteristic parameters and introducing the fuzzy mathematics theory, the state parameter information is showed by the fuzzy triangular membership function.The practices prove that the fuzzy triangular membership function can efficiently correlate the state characteristic information of equipment with the equipment performance in the evaluation of the sensing equipment state, which correctly reflects the current operation state of equipment and more satisfies the variation rule of sensing equipment operation state. The evaluation result can be the scientific basis for carrying out the state maintenance and risk evaluation of equipment..
