ABSTRACT
 Along with the progress in science and technology and the development of productive forces,torque and rotational speed measurement technology is widely applied in motor,automobile,marine transportation,diesel engine,chemical machinery, petroleum industry,metallurgy,etc.The torque and rotational speed measurement is necessary for mechanical products’development and research,test and analysis,quality test,pattern appraisal and energy conservation,security and optimized control. Therefore,the development and production of torque and rotational speed measurement system also represent the modern level of a country’s basic industry and the scientific research.
 This paper provides an overview of the research and development of rotational speed measurement system at home and abroad;then makes comparation among different rotational speed measurement systems in a classifed manner。At this stage，the speed measurement system which are widely used in Domestic。Considering the existing problems occuring in anti-interference and rapid survey during rotational speed measurement as well as new demands on survey system, Through the use of optical encoder technology，Design of a hydraulic motor based on the speed measurement system。Provides a program to achieve real-time online Speed detection, mechanical drive system to resolve the current problem of real-time measurements to improve the system anti-interference ability of a new solution.
