Testing System Of Motor And Fan Controllers

As the speeding up of the course of modernization, the need of machines’automatization and overintellectualization is in further increase. The application areaof motor and fan is enlarging, too. Meanwhile, the demands of motor controller andfan controller’s characteristics are becoming more and more strict. Then many kindsof testers are produced. Whereas during the promotion of drivers in the wide market, atool like the portable signal test source is need. All the users have the same demand.But the product on the market is just the standard signal source. Now customers aregenerally using the customized operation tool, which is produced by their cooperators.So we hope to design a tool like this: on the one hand, it can used as the portablesignal test source to examine fan and motor controller’s characteristics conveniently.On the other hand, it also can be connected to PC. We can draw up the testing processon PC and examine the characteristics of motor and fan controllers, which greatlyimprove the testing efficiency. Judging from the target customers’ demands, this kindof tool is needed from development&modifying, the technical supports before andafter sales, the production process and test process, including the tests ofcharacteristics and reliability, which has a certain market prospect.This paper faces to the market. And the object is to design a tool like this, with astrong practical usage.The main content consists of5chapters. The introduction is an analysis of theproject’s background and demand and also a summarization of concrete functions oftesting tools and the works the upper computer should finish. And it’s about choosingthe hardware&software environment of the issue’s R&D and the simpleintroduction of hardware’s development environment. The main content includes thefeature and inner part’s construction of selection chips.Then it describes the lower computer’s hardware circuit and the fluctuation placemachine’s software. This part generally illustrates the master control chip circuit, thecircuit diagram around and each part’s operation flow chart of the fluctuation placemachine’s software. It illustrates the concrete process of the upper computer and lower computer’s data interaction and also the testing operation interface and the settings oftest parameters of upper computer in detail to help testers to master the formulate oftest plan fastly and efficiently.
