OBD vehicle-mounted terminal intelligent diagnostic device and diagnostic method thereof

Abstract

The invention discloses an OBD vehicle-mounted terminal intelligent diagnostic device and a diagnostic method thereof. The OBD vehicle-mounted terminal intelligent diagnostic device comprises an MCU microcontroller, a serial port 0 module, a serial port 1 module, button control, a liquid crystal display module and a power supply module, etc. The intelligent diagnostic device performs data communication with an OBD vehicle-mounted terminal via the serial port 0. The intelligent diagnostic device performs analysis processing on the received data. The intelligent diagnostic device performs data communication with an upper computer via the serial port 1. Reading diagnosis is performed on all the modules of the OBD vehicle-mounted terminal so that judgment of problems existing in all the modules can be realized. The problems existing in the OBD vehicle-mounted terminal can be immediately judged so that the technical requirements for detection personnel can be reduced, detection visibility is enabled to be better, detection work efficiency of the product can be enhanced, production and maintenance cost of the OBD vehicle-mounted terminal can be reduced and thus preparation for batch detection is realized.

Description

technical field [0001] The invention belongs to the field of equipment detection and diagnosis systems, and in particular relates to an intelligent diagnosis and detection device of an OBD vehicle terminal and a diagnosis and detection method thereof. Background technique [0002] OBD (OnBoardDiagnostics) is an on-board automatic diagnostic system. OBD vehicle terminal integrates many functional modules such as communication module system, satellite positioning system, OBD module, three-axis acceleration sensor, antenna system, etc. With the promotion of OBD vehicle terminal application, the production output continues to increase, and there are detection problems in the production process stand out. Due to the high level of integration, there are many functions that need to be detected, and the detection efficiency is low in actual production, so it is impossible to directly determine the problem of the OBD vehicle terminal, which makes maintenance difficult and consumes m...

AI Technical Summary

Problems solved by technology

Due to the high level of integration, there are many functions that need to be detected, and the detection efficiency is low in actual production, so it is impossible to directly determine the problem of the OBD vehicle terminal, which makes maintenance difficult and consumes more manpower and time, and increases the cost of the OBD vehicle terminal.
