Research And Implementation Of MR Dampers Monitoring System Based On Wireless Communication

MR damper is a devices commonly used for control structural vibration. The existing control of MR damper is generally voltage model, just in the control of single MR damper. It not only lacks graphical monitoring of mainframe systems on the working conditions of damper, furthermore the working parameters of Damper can not be saved, and do not facilitate the work state analysis of the damper. MR dampers Monitoring System based on Wireless Communication monitors and controls the multi-MR damper controllers, and saves the work parameters of each damper, which is convenient for the engineering personnel to analyze the state of damper, also has an important significance in automation control.Based on the study of MR dampers' control theory and control methods, the overall control program of the MR dampers Monitoring System based on Wireless Communication is brought forward according to the request of the topic. The MR dampers Monitoring System based on Wireless Communication includes MR damper controller and host monitoring system. The wireless communications modules are used between MR damper controller and monitor host. After ascertaining the system structure of the program, it needs to choose a suitable program of development environment and programming.In MR dampers Monitoring System based on Wireless Communication of this paper, on the part of MR damper mainly introduces MCU signal input circuit, the signal output processing circuitry, wireless communications module circuit, as well as PWM current producing circuit, and gives the software flowchart of the controller C8051F040 ; On the portion of the host monitoring system mostly presents the hardware circuit of wireless receiver controller, receiving controller S3C44B0X and the hardware circuit design of the mainframe, and particularly introduceμC/OS-II transplantation process based on the S3C44B0X transplantation process, as well as S3C44B0X using the multi-tasking functions ofμC/OS-II to collect data of various MR damper controller, the Windows API application methods in the monitoring software of the mainframe, and gives the flowchart of S3C44B0X and mainframe software.The controlling system should use the Closed-loop control mode, by computer realizing the display, adjustment and control of each function. By the experiments showing that the control system of controlling MR dampers achieves the design requirements, and can reveal the working parameters of each MR damper control in the monitoring mainframe, achieving the smooth running, rapid and accurate controlling and easy regulation of the system.
