The utility model relates to the technical field of metering instrument maintenance, especially to a multi -core cable alignment tool. The multi -core cable alignment tool includes carrier circuit board and tool shell, and power module, detection module and processor module are integrated on the circuit board. The power module is independently separated and arranged, respectively supplies power for the processor module and detection module, realizes electrical isolation to improve safety; the detection module supports batch wiring through the multi -end input port, cooperates the logic control of processor module, and the display module directly shows the wire serial number, and the prompt module realizes sound and light feedback through the buzzer and indicator light, the storage module supports historical data call, and the input module adopts composite key to realize reset, brightness adjustment and other functions. The tool solves the problem of low efficiency and easy error of traditional manual alignment, realizes single person once wiring batch calibration, has short -circuit detection and data storage functions, improves the efficiency and accuracy of cable alignment, reduces cable loss and cost.

This application discloses a fault diagnosis method for a multi-screen display system in a new energy vehicle, relating to the field of vehicle testing. The method includes: adopting a QNX+Android multi-system architecture; transmitting the displayed video stream to the screen via a screen interface based on the QNX system; transmitting the video stream to the screen via the openWFD protocol based on the Android system; using openWFD as a front-end and back-end structure, with the Android system as the front-end and the QNX system as the back-end, and the QNX system back-end module openWFDBE receiving data from the Android system front-end module openWFDFE; wherein, based on the openWFDServer module, it connects the front-end module openWFDFE, the back-end module openWFDBE, the screen interface, and the multiple screens, serving as an intermediate processing hub for screen video stream transmission; wherein, the instrument panel runs the QNX system, while the central control, passenger side, and rear entertainment screens run the Android system.

The utility model discloses an integrated cabinet body of flywheel converter, and the cabinet body is divided into power area and control area through the partition structure, at least one pull-out box is equipped in the control area, the pull-out box is used for installing the control component and is convenient for pull-out maintenance, the partition structure includes partition frame and the baffle covered and installed on the partition frame, realizes the physical isolation of power area and control area, thereby integrates power area and control area in the same cabinet body, realizes functional isolation through the baffle at the same time, greatly reduces the overall floor area, improves single cabinet space utilization, especially suitable for the scene of higher space compactness requirement such as computer lab, energy storage power station. Through the setting of pull-out box, it is convenient to directly pull out the cabinet operation, does not need to dismount fixed bolt or removes the periphery component as a whole, and maintenance time is shortened.
