【Abstract】 A new software for the prime motor emulation system based on 80C196KC single-chip microcomputer was developed, and the functions of the governor in the system was realized with the flexible software of single-chip microcomputer. This not only dramatically simplified the circuits of the hardware, but also overcame many defects of the analog circuit, such as the complexity of its structure, the easy aging of its electronic components, susceptibility to temperature and poor anti-interference feature, thus enhancing the control accuracy, reliability and stability of the whole system. In addition, liquid crystal displays and man-machine communication interfaces were set up to transmit the operation parameters of the prime motor emulation system to the monitoring system or the PC in the form of digital signals. The operation was visual and convenient to observe. Modularization was adopted for microcomputer software compiling so that the compiling of the software was easy and simple. This software has passed test-runs and the effect has proved to be desirable.更多还原
