New-energy automobile fault diagnosis system based on IOT (Internet of Things) and cloud computing

Abstract

The invention discloses a new-energy automobile fault diagnosis system based on IOT (Internet of Things) and cloud computing. The new-energy automobile fault diagnosis system is formed by multiple new-energy automobile monitors and a new-energy automobile fault monitoring center, wherein each new-energy automobile monitor comprises a wireless communication module, a microprocessor, a current and voltage sensor, a temperature sensor, a revolution speed sensor, an accelerator pedal sensor, an electric motor monitor, a storage battery monitor, an early warning device and a power supply. The new-energy automobile fault diagnosis system disclosed by the invention has the advantages of simple structure, wide coverage range, comprehensive monitoring, intelligentization, humanization and the like, and convenience can be provided for an after-sales service department of a brand automobile to carry out unified monitoring on the fault information of new-energy automobiles needing to be monitored and protected. When a new-energy automobile of an owner is diagnosed in fault, early warning information can be transmitted to the corresponding owner by the monitoring center, convenience is provided for the owner to pay attention to and treat the fault in time, and the damage and the economic loss to the owner caused by the fault of the automobile can be effectively reduced.

Description

technical field [0001] The invention relates to a vehicle fault diagnosis system, in particular to a new energy vehicle fault diagnosis system based on the Internet of Things and cloud computing. Background technique [0002] According to statistics, about 70% of the time in the traditional car maintenance process is used to find faults, and about 30% of the time is used to eliminate faults. In order to deal with the problem of increasing difficulty in vehicle diagnosis and maintenance due to the transformation of automotive electronics, a fault diagnosis system is added to the development process of automotive electronic control systems. Drivers and passengers, ensure vehicle safety. [0003] Compared with traditional vehicles, the electrical system composition of new energy vehicles is more complex, and the degree of electronization is higher than that of traditional vehicles. Generally, it is composed of multiple subsystems, and each subsystem basically completes its ow...

AI Technical Summary

Problems solved by technology

[0004] There are high-voltage and high-current loops during the driving of the vehicle. When an electronic or communication failure occurs, if it is not discovered in time and certain measures are not taken, it may cause great harm to personal safety; It is difficult to eliminate vehicle faults by experience and maintenance methods such as traditional hand tools
