目前发动机测试仪设备多以测量和采集数据为主,功能比较单一。为此文中提出一种基于VC++的多功能发动机测试仪。该测试仪除具有一般测试仪的功能外,能自动辨识发动机状态,并根据技术规程,计算需要的性能参数,显示相应的性能信息,给出基本故障信息等。文中还介绍了测试仪硬件的基本组成,简单阐述了软件的设计思想,并详细说明了软件设计中的关键问题。
At present, the engine tester more equipment to measure and collect data, the function is relatively simple. In this paper, a multi-function engine tester based on VC ++ is proposed. In addition to the tester with the general function of the tester, the engine can automatically identify the state, and in accordance with technical regulations, calculate the required performance parameters, display the corresponding performance information, given the basic fault information. The article also introduces the basic components of the tester hardware, a simple exposition of the software design ideas, and a detailed description of the key issues in software design.
