The Development Of Distributed Control System Of Optical Components And Reflective Mirrors

The thesis discussing the research subject from shooting range photo electric and control system of the Shenguang-â…¢(SG-â…¢) mainly carries out the research and development of reflective mirror module and terminal optics module motion control system in the shooting range system. SG-â…¢system goes on research of Inertial Confinement Fusion (ICF). The system guarantees that it operates high-efficiently, reliably and steadily and is its essential important component.The control system has two kinds of control modules ("local control" and "internet control"), with responsibility for motion control of 96 electronic servo reflective mirrors and 48 final optics modules. In " internet control " mode, the system is coordinated and commanded by the unity of the central console, through TCP/IP network, receives the control orders of SG-â…¢prototype facility shooting range concentrate control system, conveys information through RS485 bus and then drives designated subsystem for moving, after finishing the movement, transfers relevant feedback information to central processing unit. In "local control" mode, through input interface, operator can control corresponding subsystem with keyboard, mouse, etc in operate scene.Systematic hardware configuration makes up of IPC, 232-485 transformation, electrical control circuitry, motor driver, motor, etc. Because system expect very much to dependability and stability, hardware systematic components and parts adopt famous commercialized product of brand. Develop electrical control circuitry with myself, take PIC16F877 microcontroller as the basic control chip manufacture the electrical control circuitry. In the layout, the wiring takes the electric circuit anti-jamming measure. Adds the power line width, reduces the loop resistance. Thickened will grounding line, the double circuit boards large areas of copper, grounding circuit loop Crackdown Mission, circuit board held a retreat coupling capacitor configuration to increase resistance to noise.The systems software regards configuration software, VC++6.0 as the tool and realizes forming the collecting and distributing type control system through RS485 bus, carry on the communication with the unity of the central console through the LAN. The design demonstrates direct-viewing, man-machine connection friendly contact surface, and can show the real-time state motor. It can realize that directly control at the scene and Internet centralized control. The communication module adopts Winsock controls based on TCP/IP agreement to carry on communication, make communication simple and trustiness...
