【Abstract】 For improvement of the precision of hydro-mechanical model tests, an intelligent acquisition and control system is developed. The system can reduce the work load of experimental technicians, and realize the real-time, continuous, and synchronous measurement during the experimental process. By integration of the control section with the data acquisition section into a single bench, the system can be operated under manual control or automatic control, and also has the functions of remote control and local control. Application shows that the error of the system is smaller than 05%, which meets the requirement of experimental precision.更多还原
