Research And Design Of Dam Safety Monitoring Simulation And Experiment System

Dam safety monitoring simulation and experiment system is a dynamic analogies system. It offers a good experiment scientific research environment to the culture the students of water conservation and hydroelectricity speciality of university, reinforces the segment of teaching and experiment. The students' ability of thinking and doing is be increased. It is significant that we research the dam safety monitoring simulation and experiment system.In this paper we introduce the integrate design of the dam safety monitoring simulation and experiment system, it includes two sections: the shape change analog subsystem of dam and safety monitoring subsystem of dam. The shape change analog subsystem of dam is the most important part in the whole system and it also is the essence of this paper. The design proposal of dam safety monitoring simulation and experiment system is be screened from the requirements of economy, reliability, simple and so on. So we choose the centralized control program based on signal computer. The control of stepper motor plays an important part in the shape change analog subsystem of dam, it determines success-fail of the dam safety monitoring simulation experiment. Elevation and subsidence control of stepper motor is discussed particularly in this paper in order to ensure the accuracy of the stepper motor control.The design of software matching the dam safety monitoring simulation and experiment system is one of the key sections of whole system. It described particularly design of application software of the shape change analog subsystem of dam and discusses several key questions which is sloved by high-resolution performance counter and multi-thread in this subsystem. For example, the frequency control of stepper motor, the asynchronous operation of many stepper motors and so on.
