The invention discloses a charging pile state evaluation method and system based on a CAN message. The method comprises the following steps that a CAN bus message between a charging pile and an electric vehicle is acquired and preprocessed; performing protocol reverse operation according to the preprocessed CAN bus message; constructing an electric vehicle charging pile operation state comprehensive evaluation index system; and based on the protocol reverse result and the evaluation index system, using an uncertain analytic hierarchy process to evaluate the operation state of the charging pile. According to the method, the running state of the charging pile is evaluated by combining protocol reverse with the uncertain analytic hierarchy process, comprehensive detection and evaluation of the running state of the charging pile are achieved, meanwhile, bit phase AND and other operations are used, a reverse result with a high confidence rate can be rapidly obtained, and the detection efficiency can be improved while the state evaluation accuracy of the charging pile can be guaranteed.

    本发明公开了一种基于CAN报文的充电桩状态评估方法及系统,方法包括以下步骤:获取充电桩与电动汽车之间的CAN总线报文并进行预处理;根据预处理后的CAN总线报文进行协议逆向操作;构建电动汽车充电桩运行状态综合评估指标体系;基于协议逆向结果和评估指标体系,使用不确定层次分析法对充电桩运行状态进行评估。本发明通过协议逆向结合不确定层次分析法对充电桩运行状态进行评估,实现充电桩运行状态的全面检测与评估,同时使用比特相与等操作,能够快速获得高置信率的逆向结果,能够在保证充电桩状态评估准确性的同时提高检测效率。
