This paper introduced the working principle of speed device, described in detail the composition of the system, principles and testing methods. Hardware and software systems used to measure the process and measurement process. With the traditional speed devices compared to this overspeed governor is simple in structure, innovative, easy-to-implement features. Throughout the experiment proved that within the governor have made a good result, the system has a good steady performance of accuracy and dyn...
