Commercial vehicle computer decoder

Abstract

The invention discloses a commercial vehicle computer decoder which is a computer detection terminal for commercial vehicle fault detection and maintenance. The hardware design of the product adopts a modular structure which comprises a power module, a commercial vehicle communication interface module, a display module, a standard serial-port module, a power self-identification module and a storage module. Based on the traditional commercial vehicle fault detection, the invention provides an intelligent detection scheme to realize automatic and intelligent fault detection of a commercial vehicle; and after the intelligent detection scheme is popularized and used, the commercial vehicle fault detection efficiency and accuracy can be improved. The commercial vehicle computer decoder is connected with the commercial vehicle; the decoder sends corresponding commands to a commercial vehicle computer according to corresponding protocols; and the commercial vehicle computer performs self setting or sends the various requested data to the decoder according to the commands. The decoder processes the obtained data and sends the data to the storage module and the display module, and displays abnormal data in color. The commercial vehicle computer decoder disclosed by the invention has a self-learning function and a fault alarm color display function.

Description

technical field [0001] The invention relates to a computer decoder which can be used for fault diagnosis of various commercial vehicles. Background technique [0002] A commercial vehicle engine is a typical comprehensive complex system. From a structural point of view, it is an electromechanical system composed of mechanical, electrical, hydraulic and other subsystems, which belongs to a multi-layer hierarchical structure; from the perspective of fault characteristics, it often manifests as Fault symptoms are complex, and the cause relationship between faults is complicated. Due to the limitations of fault diagnosis technology and application, the engine fault detection in my country's commercial vehicle manufacturing industry is still in the manual detection stage, mainly using outdated detection methods and means such as ear listening and hand touch. This method is not only inefficient and cannot meet the needs of modern large-scale production, but also due to the influe...
