Automobile generator testing system

Abstract

The invention provides an automobile generator testing system. The automobile generator testing system comprises a computer, a conditioning circuit, a temperature control box, a load box, a generator driving unit and a sensor transformation unit. The computer is connected with the conditioning unit, the temperature control box, the load box and the generator driving unit. The conditioning circuit is connected with the load box, the generator driving unit and the sensor transformation unit. The generator driving unit comprises a variable frequency motor, a braking circuit and a frequency converter. The variable frequency motor, the braking circuit and the frequency converter are sequentially connected. The frequency converter is connected with the computer and the conditioning circuit. Speed control over an automobile generator by the computer includes open-loop control and closed-loop control. The automobile generator testing system is simple in structure, large in comprehensive testing item number, high in interference resistant capacity, wide in temperature range, good in data processing, good in accuracy, easy to operate and high in working efficiency.

Description

Technical field [0001] The invention relates to a test experimental device for simulating the working state of an automobile generator under various environments and conditions, in particular to a test system for an automobile generator. Background technique [0002] Today’s widely used automobile generator test benches require manual recording of the test data, and the items or technical indicators that can be tested on the same test bench are very single; if you need to test all the main technical indicators of the automobile generator test system, multiple sets are required Different types of test benches to complete. [0003] In addition, the current automobile generator testing technology has poor anti-interference ability, small test temperature range, insufficient signal data processing, poor accuracy, and complicated operation. Summary of the invention [0004] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a graphical...
