1. A design method of a centralized control system of a coal preparation plant is characterized in that coal preparation plant equipment is used as a control object, an object-oriented design thought is applied, an equipment object is abstracted, the equipment object comprises two parts of equipment attribute and equipment function, the equipment attribute mainly realizes interface connection of equipment input and output signals and setting of relevant characteristics of the equipment, and the design method comprises the following steps:

  • based on the control modes of different devices in the centralized control system of the coal preparation plant, the control parameters of the devices in the centralized control system of the coal preparation plant are packaged and divided into shared parameters, owned parameters and output parameters;

    wherein the content of the first and second substances,the common parameters are input parameters of all the devices, and the common parameters comprise;

    the all-line emergency stop parameters are input, and all equipment is in emergency stop when the input is effective;

    the full-line remote instruction parameters are input, and all equipment is converted into a remote control linkage working mode when the input is effective;

    the method comprises the steps that full-line local instruction parameters are input, and when the input is effective, all equipment is converted into a local maintenance working mode;

    resetting the instruction parameters of the whole line, and resetting the alarm of all the equipment when the instruction parameters are input to be effective;

    testing parameters of the full-line secondary loop, and converting all equipment into a secondary loop testing working mode when input is effective;

    the self-contained parameters are input parameters of the selected equipment, and the self-contained parameters comprise;

    the centralized control instruction input parameters are used for the operation of the upper computer on the equipment and the operation among the equipment;

    the field hardware input parameters are used for equipment hardware instructions and signal input, and equipment locking signals;

    a time setting parameter for setting a time parameter related to equipment control of the coal preparation plant;

    the equipment characteristic parameters are used for setting the control types of the equipment of the coal preparation plant;

    the output parameters comprise output instructions of all the devices and device operation state parameters.
