Auto testing system for vehicle generator

In the vehicle generator manufacturer, in order to ensure the quality of products, generators are needed to be tested to make sure whether the performance indices can meet the requirements. This paper has just designed a generator testing system, which is consisted by touch screen and PLC. In this system, PLC will control the frequency converter to drive motor and make the motor have different rotational speed. Motor drive the generator to generate electricity, and then this system will detect whether voltage and current generated by generator in different rotational speed can meet the demand automatically. With the purpose of increasing Human-Machine User-friendliness, control press-button and display would use HMI touch screen to achieve. It can make the test procedure quite easy and convenient. At the same time, this testing system will be disposed a micro-printer, which can help to print and record every test results.
