Cement firing control and optimization double-layer cooperative control system based on Internet of Things

Abstract

The invention discloses a cement firing control and optimization double-layer cooperative control system based on the Internet of Things. The cement firing control and optimization double-layer cooperative control system comprises a cement firing data acquisition module, a cement firing in-place optimization control module, a cement firing data transmission module and a cement firing optimizationanalysis configuration module. The cement firing data acquisition module comprises a data acquisition sensor, a PLC (Programmable Logic Controller) and a DCS (Distributed Control System), the data acquisition sensor acquires working and electrical parameters and transmits the working and electrical parameters to the PLC, meanwhile, the PLC directly acquires switching value, and the PLC transmits information to the DCS; the cement firing in-place optimization control module comprises a decomposition furnace in-place optimization control module and a grate cooler in-place optimization control module, and the decomposition furnace and grate cooler optimization control modules analyze the data to obtain optimization control parameters; and the cement firing data transmission module uploads thedata of the PLC and the DCS to the cement firing optimization analysis configuration module. The system has the advantage of accurate and reliable control effect.

Description

technical field [0001] The invention relates to the field of cement firing control systems, in particular to a two-layer collaborative control system for cement firing control and optimization based on the Internet of Things. Background technique [0002] Cement firing equipment includes preheater, calciner, rotary kiln, grate cooler, etc. These equipments work together to complete the firing of cement. The existing cement firing control system is based on the working parameters of the equipment, and realizes automatic control by simply comparing the working parameters with the preset parameters. For example, simply comparing the internal temperature of the calciner with the preset temperature, when the internal temperature is lower than the preset temperature Then increase the internal temperature of the decomposition furnace. The control effect that this control system can achieve is relatively poor, and it is difficult to achieve precise control. Contents of the invent...
