发动机试验数据自动采集与分析系统

Development of a PC-based Data Acquisition and Analysis System for Engine Performance Test

在调查研究国内外发动机自动测试技术的基础上，提出了一种借助微机实现发动机测试数据自动采集与分析的方案，完成了硬件配置设计并研制了数据采集与分析的全部软件。用所研制的发动机试验数据采集与分析系统能测试9个性能参数，并可扩充到16个。给出了使用本系统的测试结果和在柴油机上进行负荷特性和调速特性测试的实例。

After investigating various automated measurement techniques,domestic and abroad, a PC-based automated data acquisition and analysis system for engine test is developed, 9 parameters of the engine being tested can be measured by that system. As the application examples, the test results of the diesel engine load characteristics and control characteristics, which were obtained by using this system are given.
