Vehicular equipment information monitoring system

Abstract

The equipment information inspecting system of automobile style relates to one PC / 104 bus type data gathering equipment, one harsh electrical conditioning card, one domination / alarm and one location communication module. The data gathering equipment relates to stack type PC and the data gathering module, storage module, CAN bus module, display equipment, input equipment and electrical source connecting with the stack type PC. The stack type PC owns inspecting software and software of secondary planet location communication system to gather, dispose and inspect signal of the up-installing equipment on the modification vehicle and all kinds of state parameters of it. Manages the vehicle location communication, maintaining and using management, wireless network transmission, audio and video frequency display. The harsh electrical conditioning card, is used to adjust signal in many forms sent by the up-installing equipment on the modification vehicle to figure signal and input the figure signal to the data gathering module. The domination / alarm connects with data gathering module to output the controlling signal and alarm signal. The location communication module connects with the stack type PC to inspect the real location information about the vehicle by secondary planet.

Description

technical field [0001] The invention relates to a vehicle-mounted equipment information monitoring system, which belongs to the technical field of automotive electronic equipment. Background technique [0002] With the continuous development of automotive electronics technology, the requirements for vehicle condition monitoring and fault diagnosis are gradually increasing. In addition, there are more and more applications such as automotive intelligent navigation, audio and video playback, etc., requiring the system to provide increasingly powerful data processing, computing, and information management capabilities. [0003] Existing automotive electronic systems for vehicle condition monitoring and fault diagnosis are mostly designed based on single-chip microcomputers, which display text or graphics on the screen; use the CAN interface as the source of vehicle condition information, and obtain various state parameters of the vehicle through the CAN bus of the vehicle; Real...

AI Technical Summary

Problems solved by technology

The equipment on these modified vehicles is mainly selected from general-purpose equipment. The equipment itself does not have an information output interface and cannot be connected to the CAN network of the vehicle. Therefore, information cannot be directly transmitted through the CAN bus. It is difficult to realize the status monitoring of vehicle equipment according to existing solutions. diagnosis
