Method and apparatus for testing UPS control unit

Abstract

The invention relates to UPS control unit testing method. In order to increase development and shakedown test of UPS control software and system to make the test have better safety, the method includes the following steps: offering a UPS control unit and a UPS simulation complete machine; installing the former to the latter; using the UPS simulation complete machine to finish the test. The invention also offers a UPS control unite testing device.

Description

【Technical field】 [0001] The present invention belongs to the technical field of Uninterruptible Power Supply (hereinafter referred to as UPS), and in particular relates to a method and device for testing a UPS control unit. 【Background technique】 [0002] The UPS control unit is the core component that controls the entire working process of the UPS, and it is mainly composed of the main control chip and some peripheral circuits. The main control chip and its software are the core of the UPS control unit. It mainly completes the collection of data such as voltage, current and temperature of the UPS power part, and performs calculation and processing of the collected analog data, as well as logical judgment and analysis of the collected digital signals. Processing, and sending control signals to the power part, to control the action of each device in the power part, complete the conversion of the working state of the UPS, and at the same time receive and send the signal outpu...

AI Technical Summary

Problems solved by technology

Therefore, software developers must wait for the completion of the UPS hardware design before software debugging, thus delaying the development and debugging progress of the UPS control software and the entire system

[0005] (2) When debugging in the initial stage of UPS control software development, it is difficult to ensure the correctness of the control software because the software has just been written

The UPS control unit plays a key role in the whole machine. Once the software timing is inaccurate or the logic error occurs, it is easy to cause damage to the whole UPS components or even cause the danger of explosion.

[0006] (3) Since the UPS machine is often working in a normal state, it becomes difficult to test some abnormal protection states

For example, for the detection and protection functions of internal device overvoltage and other faults, it is impossible to test the actual UPS system

[0007] (4) The software test of the control unit on the UPS machine is very random, and the test method and test content may be different for different testers

If there is an error in the control unit due to production reasons, but the production debugging personnel did not find it, once it is installed on the UPS machine for debugging, it may cause damage to the whole machine, and using the whole machine to debug is time-consuming and laborious
