Coach chassis harness protection and alarm device and method thereof

Abstract

The invention relates to a coach chassis harness protection and alarm device, which comprises a chassis harness and a communication detection part, wherein an electric conduction metal film layer is arranged in a bellows of the chassis harness; the communication detection part comprises a harness protection and alarm system ECU (Electronic Control Unit), a display screen and an alarm signal collection node; the alarm signal collection node is connected with the electric conduction metal film layer; the alarm signal collection node of the alarm device is used for monitoring a potential difference between the electric conduction metal film layer and a chassis frame, and sending monitoring data to the harness protection and alarm system ECU; and when the potential difference is less than an experience number, the harness protection and alarm system ECU prompts a driver to pay attention to fault messages and fault points. The coach chassis harness protection and alarm device can be used for monitoring the safe state of the coach chassis harness in real time, accurately positioning harness abrasion alarm and fault points, and troubleshooting harness installation vulnerable points in a new product sample car stage, so that the outbreak of harness installation hidden danger on a batch product car is avoided, and the hazards of car harness ignition and after-sale troubleshooting are avoided.

Description

technical field [0001] The invention relates to the technical field of passenger car electrical technology, and more specifically relates to a device capable of implementing a protection and alarm function for the wiring harness of a passenger car chassis and a method thereof. Background technique [0002] With the continuous development of bus technology, the number of on-board electrical equipment continues to increase, and the bus wiring harness system becomes more and more complex. Coupled with the continuous improvement of market requirements for bus comfort, the difficulty of bus space layout is increasing day by day, which is left to the wiring harness system. space is very limited. Since the chassis wiring harness, which is a key part of the bus electrical system, carries the most important functions of the vehicle, such as power supply and power chain data drive, and there are many types of wiring harnesses, large volume, and limited wiring space, the installation r...
