Vehicle driving motor test stand data acquisition system based on LabVIEW

Abstract

The invention relates to a vehicle driving motor test stand data acquisition system based on LabVIEW, which is used for acquiring data in a vehicle driving motor test stand. The data acquisition system comprises the test stand and a data acquisition system. The test stand is used for realizing test for a vehicle driving motor, and the data acquisition system matches with the test stand and consists of a sensor, a data acquirer and a computer with a LabView development platform. The vehicle driving motor test stand data acquisition system can guarantee that stored test data cannot be lost when acquired at a high speed and waveforms are displayed in real time, callback and frequency-domain of data of the waveforms are realized after a test, and a test report in a fixed format is generated. In addition, the vehicle driving motor test stand data acquisition system can be used for evaluating performances of an electric vehicle with hybrid energy sources and optimizing a control strategy of a hybrid energy resource management system, is used as a meter display board and the like of the electric vehicle with the hybrid energy sources and a pure electric vehicle, and is a currently available electric vehicle data acquisition system with complete functions.

Description

technical field [0001] The invention relates to the technical field related to the reliability of a drive motor system for a vehicle, in particular to a data acquisition system for a test bench of a drive motor for a vehicle based on LabVIEW. Background technique [0002] Since the beginning of the 21st century, energy and the environment have had an increasing impact on human life and social development. The development of electric vehicles has become an inevitable choice for governments around the world to develop the automobile industry and improve the overall competitiveness of the national economy. Vehicle drive motor is the core component of electric vehicles, and its performance determines the quality of electric vehicles. However, the current bench test used to evaluate the performance of electric vehicle drive motors still has the problems of low sampling rate, poor synchronization, and imperfect functions. Signals such as current, voltage, temperature and SOC need...

Problems solved by technology

[0011] Although the above patent application documents or patent documents more or less involve the test bench data acquisition system based on virtual technology, they are all data acquisition systems for a single mechanical component or electronic component; The development of the data acquisition system for the test bench of the vehicle drive motor composed of mechanical components and electronic components; as far as the applicant knows, for the test bench of the vehicle drive motor composed of mechanical components and electronic components There is little research on the data acquisition system at home and abroad. At present, there is no relatively complete data acquisition system for the test bench of the vehicle drive motor.
