Wireless communication-based modularized automatic cable checking device

Abstract

The invention discloses a wireless communication-based automatic cable alignment device. The device comprises a terminal display module, a wireless primary module, a wireless secondary module, an output module and an acquisition module, wherein the terminal display module and the wireless primary module are wirelessly connected by adoption of WiFi or Bluetooth; the wireless primary module and thewireless secondary module are connected by adoption of LoRa, or the terminal display module and the wireless secondary module are connected by adoption of WiFi; the wireless primary module and the output module or the acquisition module are in wired connection by adoption of CAN, 485, 232 or an Ethernet; and the wireless secondary module and the output module or the acquisition module are in wiredconnection by adoption of the CAN, 485, 232 or the Ethernet. The terminal display module controls the level of pins in the output module one by one; acquisition results are returned through the acquisition module; and the terminal display module carries out matching verification. The device has the beneficial effects that one-to-one corresponding cable structures can be automatically detected andmarked without accessing wiring harnesses in the cables to the interfaces of the input and acquisition modules according to fixed numbers, so that the detection time is greatly shortened.

Description

technical field [0001] The invention relates to the fields of vehicle manufacturing, multi-core cable lines and equipment detection in power systems, in particular to the system-level detection of equipment with multiple interfaces, long distances, and passing through junction boxes and splitters. Background technique [0002] There are a large number of multi-core cables in vehicle manufacturing and power systems. The above-mentioned multi-core cables will also pass through many junction boxes and splitters, with long distribution distances and many interfaces. At present, the commonly used method is to use a multimeter (or light) to check the on-off. For long-distance lines connected by multiple junction boxes like EMUs, or multi-core cables that span houses in similar power systems, it is necessary for staff at both ends of the cable to assist with communication devices such as walkie-talkies or mobile phones. Due to the noisy environment on site, complicated and chaotic...
