Abstract

The invention provides a flexibility testing system of an engine, and the flexibility testing system comprises a data acquisition terminal and a test upper computer connected by a USB (universal serial bus) communication module, wherein the data acquisition terminal is connected with a sensor; the test upper computer adopts VC for development and comprises a data processing module; the input end of the data processing module is connected with the output end of the USB communication module; the data processing module is a data process DLL (dynamic link library) developed by a user under the development environment of a developable dynamic link library; and in the development process, the user can develop the data processing module applicable to new test tasks by only conforming to the specified interface definition rule, and also can rewrite the data processing process in the original data processing DLL. According to the flexible testing system, the development efficiency of the testing system of the engine can be obviously improved and the cost and risk for development can be reduced.

Description

technical field [0001] The invention relates to the technical field of engine test systems, in particular to an engine flexible test system. Background technique [0002] The level of engine testing technology is an important symbol to measure the development level of a country's automobile industry, and the development of the automobile industry cannot do without the improvement of engine testing technology. There are thousands of engine manufacturing enterprises in our country, and each enterprise also has a different number of engine test platforms. Together with relevant research institutes and colleges and universities, it is estimated that there are tens of thousands of test platforms nationwide. However, most of these test benches are test systems in the traditional sense, which require manual adjustment of various working conditions, visual readings, and handwritten record status. These test methods and methods can no longer meet the basic requirements of modern test...
