The Design And Realization Of Large-screen Centralized Control System

The emergence of centralized control systemcombined smart devicetogetherwhich controls the use of co-ordination to achieve the maximum expectedeffect. Large-screen control system is the set of screen device, matrix control deviceand image processor equipment which achieves the organic combination of the deviceto control and use together, which can realize the equipment linkage and displayingimage signals as it is required.Generally a big-screen control system has an input source and output display,only to achieve the general switching function, and the protocol code ofcontrolleddevice is integrated in the program, which cannot be changed. IT is this system thatchanged the traditional situation,which will raise the degree of simulation of customerterminal and make it easier to use.We configured the devices and signal informationflexibly by reading the DLL files and XML files makes the system versatile. Onlyneed to modify the configuration file or less relevant part of the code, you can use inother large-screen control system,and reduce the cost of the project,as well as makelarge-screen control system simplifies operation and maintenance,which improve theresource utilization. Better coordination of each device and full play performance ofthe devicecan also come trueThis article focus on designing large-screen control system architecture,functional modules, researching the appropriate implementation technology, the mainfeatures include: centralized control system client achieves simulation controlinterface and corresponding operation, control terminal in response to a commandclient linkage and equipment operation, control terminal to read the device protocolDLL files and configuration XML file so that all organic combination of thecontrolled device can realize, IPC will be collected in the control card for controllingthe corresponding program combines end calls, etc.. Wemainly carried outtechnology research on the simulation interface painted screen technology, XML andDLL technology, and the network data transmission.
