Abstract

The invention discloses a car monitoring and diagnosing system comprising a monitoring and diagnosing system and a monitoring and diagnosing car. The car monitoring and diagnosing system is characterized in that the monitoring and diagnosing system is used for carrying out data collection and compression to the data information of car performance monitored and diagnosed by each sensor mounted on the car through a CAN (Controller Area Network) bus or a KWP (Key Word Protocol) bus via an information unit and then wirelessly transmitting the collected data to a monitoring server in a main monitoring center through a wireless network base station via a GPRS (General Packet Radio Service) system; the monitoring server in the main monitoring center is used for carrying out data decryption, treatment and storage after receiving the data; and each sub-monitoring station can also be used for receiving the data sent back by the information unit through the internet via the server in the main monitoring center. The system can be used for monitoring and diagnosing the performance and the running state of the car in real-time and timely giving out a judgment and a choice and can realize location tracking, remote monitoring and remote calibration of the car. The system has the characteristics of good practicality, full and rapid detection and low cost.

Description

[0001] technical field supervisor [0002] The invention relates to an automobile monitoring and diagnosing system, which belongs to the field of automobile safety detection. Background technique [0003] At present, the inspection of transport vehicles mainly relies on the motor vehicle inspection center. The inspection information during the annual inspection of motor vehicles is single, the inspection content is not comprehensive, the inspection cycle is long, and the investment is high, especially for large-scale transportation that loads important materials and special products all year round. For vehicles, such as oil transportation, the performance of these vehicles is of great importance. Once a problem occurs, the consequences are unimaginable. Therefore, it is very necessary to keep abreast of the performance of vehicles, if we can timely discover potential safety hazards in vehicle transportation, timely judge and deal with vehicle accident hazards, and escort the s...
