Vehicular equipment information monitoring system

Abstract

The invention relates to a vehicle-mounted equipment information monitoring system. The system includes: a PC / 104 bus type data acquisition device, including a stacked PC, a data acquisition module connected to the stacked PC, a storage module, a CAN bus module, a display device, an input device and a power supply, and the stacked PC is equipped with a monitoring Management software and satellite positioning communication system software are used to collect, process, and monitor the signals of the bodywork equipment of the refitted vehicle and various state parameters of the vehicle, as well as to monitor vehicle positioning communication, maintenance and use management, wireless network transmission, automatic navigation, audio, etc. Management of video playback; a strong electric conditioning board, used to condition various forms of signals sent by the bodywork equipment of the refitted vehicle into digital signals, and input the conditioned digital signals into the data acquisition module; a control / alarm, its It is connected with the data acquisition module to output control signals and alarm signals; a positioning communication module is connected with the stacked PC to measure the real-time positioning information of the vehicle through satellites.

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
