System for quickly diagnosing automobile state in real time

Abstract

The invention belongs to the technical field of automobile working state monitoring and diagnosis, and particularly relates to a system for rapidly diagnosing an automobile state in real time. The system comprises a diagnostic instrument and a control center. The diagnostic apparatus can work independently without being separated from the control center, and can also work under the control of the control center so as to adapt to different application scenes. The system supports various diagnosis protocols, such as a J1939 protocol, an ISO15765 protocol and an ISO14229 protocol, can diagnose abundant automobile states, such as automobile voltage stabilization signals, fuel injection quantity signals, a DPF regeneration state, an SCR injection state, an EGR state, a TVA state and the like, and has the advantages of being high in real-time performance, high in transmission speed, easy to operate, accurate in diagnosis result, high in portability and the like. When in use, the device can be assembled on a vehicle, and long-time and large-capacity storage can be carried out on data related to diagnosis for subsequent analysis.

Description

[0001] the field [0002] The present application belongs to the technical field of vehicle working state monitoring and diagnosis, and in particular relates to a system for rapidly diagnosing vehicle states in real time. Background technique [0003] With the rapid development of the automobile industry and the national economy, automobiles have gradually become more and more popular and popularized as an indispensable means of transportation such as travel and transportation. In the process of using a car, various problems will inevitably occur. If the car has problems in the process of driving, it will bring immeasurable losses and impacts. Therefore, how to effectively diagnose and monitor the status of automobiles is a concern of many enterprises and scholars. [0004] Vehicle status diagnosis is a technology to check the status of the vehicle through special instruments and equipment. It can test some performance indicators of the car and find faults without affecting...
