Description

technical field

[0001] The invention belongs to the technical field of cement kiln control systems, in particular to an open cement kiln intelligent optimization expert system with high online rate. Background technique

[0002] The cement rotary kiln is the main equipment for burning the raw material prepared by grinding to the clinker under high temperature, and it is the "heart" of the dry process cement production line. The cement rotary kiln mainly emphasizes the close coordination of "wind, coal, material, and speed", so the system is a process system with a large lag and complex coupling relationships among multiple variables, that is, when adjusting any variable, this variable must be considered Effects on other process variables. With the development of industrial intelligent technology, many research institutions have closely combined industrial intelligent technology with the automatic control of process materials, and developed various forms of intelligent exper...

Examples

Embodiment 1

[0019] An open cement kiln intelligent optimization expert system with high online rate, referring to figure 1 , including the expert control system server ( figure 1 The expert system server in), the switch and the DCS control system, the DCS control system is equipped with a dedicated DCS function module and a proprietary control data access method, the expert control system server is connected to the data server in the DCS control system through a two-way communication through the switch, There is a bias device connected between the expert control system server and the DCS control system. The expert system control data is connected to the control mode with bias Bias, while maintaining the operator interface input. On the premise of following the operating habits, the expert system not only realizes the The two-way intelligent control of the cement kiln, more importantly, completely guarantees the safety of the production system. In addition, in view of this design concept,...
