Car engine synthesis analyzer automatic testing and analyzing system based on network

Abstract

The invention relates to an automatic test and intelligent analysis system of an automotive engine integral analyzer based on a network, which is characterized in that: in any contact of a local area network, a signal probe of the automotive engine integral analyzer can be directly arranged on any circuit of the automotive electronic system to obtain relevant electric signals by using a computer mouse and the automotive lead does not need to be repeatedly punctured by a line puncture device, which saves a great deal of operation time for preparing and switching test point without the need of field collection; the invention can not only conduct automatic test on the automobile or each automotive assembly experiment table, but also control the automotive engine integral analyzer to conduct remote automatic measurement in the local area network; the invention has the automatic comparative analysis function on standard signals and measured signals, and all the analysis process can be shown to the students vividly through a projector and an electronic whiteboard, thus the invention can be used for large-area occupation education and professional technique training, technical grade check and skill identification.

Description

Technical field [0001] The invention relates to a network-based automatic test and intelligent analysis system for an automobile engine comprehensive analyzer, in particular, it can be implemented in a local area network to perform remote automatic test and intelligent active analysis of various electrical signals of a car or automobile assembly test bench . Background technique [0002] In order to improve the dynamics, economy, comfort and environmental protection of automobiles, many kinds of electronic control systems are generally installed in current automobiles, such as engine electronic control system, automatic transmission electronic control system, brake anti-lock brake electronic control system, etc. Some have become standard configurations, such as electronically controlled airbags, electronically controlled automatic air conditioning, electronically controlled central locks, etc., and with the development of electronic technology, there are developments in the direc...

AI Technical Summary

Problems solved by technology

But the known comprehensive analyzer of automobile engine is accompanied by auxiliary tools such as multiple probes, dolphin clips and wire stabbers. Relevant electrical signals can be collected and analyzed manually by opening waterproof plugs, etc. On the one hand, it takes too long to prepare for data analysis. It often takes more than 20 minutes to prepare a signal.

On the other hand, it will destroy the original water resistance, dust resistance and airtightness of the car, and even cause some car electronic components to fail early

Third, the automotive engine comprehensive analyzer can only be analyzed on site. When the data collection site is not suitable for people to enter (excessive exhaust emissions are harmful to the body, or dangerous situations such as speeding may occur during limit tests in scientific research), the test work is often unable to proceed

Fourth, the data display screen of the automobile engine comprehensive analyzer generally uses a 17-inch or smaller display, and the number of people who can observe the data at the same time is limited, which is not suitable for large-scale professional technical training and vocational education and teaching activities

Fifth, there is currently a large shortage of senior technical personnel in the automotive service industry who have comprehensively mastered the measurement and analysis of automotive electronic control system sensors, actuators, and ECU signals. Too long and too cumbersome, it is difficult to conduct in-depth assessment and appraisal work in this area
