Abstract

The invention discloses a communication data link health state test device, system and method of an electric vehicle charging facility. The electric vehicle charging facility comprises a charging control unit and a charging pile main control plate, wherein the charging control unit is connected with and communicates with charging pile main control plate through a CAN bus. The test device comprisesa communication simulation and fault detection unit, a CAN transceiver, a human-machine interaction unit and a power supply. The test device is accessed to the CAN bus through the CAN transceiver. Auser sends a test command signal to the communication simulation and fault detection unit through the human-machine interaction module. The communication simulation and fault detection unit selects acharging control unit detection module or a charging pile main control plate detection module to execute corresponding tests according to the test command signal, thereby obtaining test result data offault states, fault types and fault positions of a CAN communication link. The communication simulation and fault detection unit of the test device transmits the test result data to the human-machineinteraction module for outputting. According to the invention, human resource cost of the link test can be reduced and test quality and efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of CAN bus communication testing, in particular to a device, system and method for testing the health state of communication data links of electric vehicle charging facilities. Background technique [0002] As a field bus, CAN bus is widely used in the field of industrial control, and has the advantages of high performance, high reliability, easy development and low cost. Due to the CAN communication between the main control board of the charging pile and the billing control unit or abnormal interference during the design, debugging and use of the application system, the CAN bus system cannot work normally. During actual use on site, it is necessary to ensure that the CAN bus is in normal working condition and to be able to detect the cause of the failure in case of communication problems. [0003] In addition, in the usual CAN bus test, it is tested by sending and receiving messages manually. In manual te...
