Online monitoring system and online monitoring method for motor of electric automobile

Abstract

The invention relates to online monitoring technology, in particular to an online monitoring system and an online monitoring method for a motor of an electric automobile. The online monitoring system comprises a motor controller arranged on the electric automobile, a motor serving as a power driving unit of the electric automobile, and a remote monitoring management center; and the motor controller of the electric automobile directly monitors data such as various parameters of the motor controller and the motor, the running state of the motor and the like, and sends the data to the remote monitoring management center for monitoring management. The online monitoring system can directly monitor the actual running state of the motor of the electric automobile, reflects the running state of the motor of the electric automobile in real time, and realizes control of the motor state such as online tracking, monitoring, fault early warning and the like so as to discover the potential safety hazard of the motor, stop the ineffective control of the motor controller on the motor, prevent accidents and provide important safety technical guarantee for the personal safety of a driver and passengers.

Description

Technical field: [0001] The invention relates to the technical field of on-line monitoring, in particular to an on-line monitoring system and an on-line monitoring method for an electric vehicle motor. Background technique: [0002] At present, real-time online monitoring, scheduling and intelligent management of automobile operation are important technical guarantees to ensure the safe and reliable operation of electric vehicles. Many automobile manufacturers have also equipped their products with this system. The data collected by real-time online monitoring of automobiles is : Car start or brake or stop, car fuel tank fuel level, tire pressure, car displacement, vehicle speed, anti-theft, door opening and closing, video and other information, but there is basically little research on data acquisition and fault diagnosis of the car power system. [0003] Recently, with the vigorous promotion of electric vehicles, the development of electric vehicles has broad prospects. It...
