DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0014] Environmental protection is the most important part of the current production process. In addition to polluted wastewater and waste gas, energy waste and material waste are also part of the current environmental protection. A variety of pollutants and wastes will be generated in the printing and dyeing process. Therefore, pollution monitoring and pollution treatment of environmental protection equipment in the production process are also part of the current production. However, long-term use and monitoring of environmental protection equipment can easily cause some unnecessary energy consumption. For this reason, the present invention provides a collaborative synchronous control system for environmental protection equipment in production, referring to Figure 1 As shown, the technical solution is as follows: The printing and dyeing process segmentation module obtains all the production control processes in the printing and dyeing process, performs control cluster analysis on the production control processes according to the pollutants generated in the production control processes, and divides them into multiple control monitoring levels; A printing and dyeing control network generation module generates a basic printing and dyeing control network according to the production control process, assigns a control weight to the basic printing and dyeing control network according to the control monitoring level, and obtains a preliminary printing and dyeing control network; A printing and dyeing control process monitoring module generates a printing and dyeing control process function according to the printing and dyeing control process, establishes a printing and dyeing control parameter monitoring model, and monitors the printing and dyeing control process function; The key control parameter association module of printing and dyeing obtains the equipment control parameters of the production control process, maps the equipment control parameters to the control weights of the preliminary printing and dyeing control network, associates various environmental protection equipment control parameters according to the control weights of the preliminary printing and dyeing control network; and initializes the environmental protection equipment control parameters; The environmental protection equipment control parameter weight update module analyzes each of the equipment control parameters according to the printing and dyeing control parameter monitoring model, updates the environmental protection equipment control parameters according to the equipment control parameters, generates a parameter printing and dyeing control network and controls the monitoring and processing frequency of the environmental protection equipment; and performs collaborative control and collaborative processing according to the printing and dyeing control process function, the parameter printing and dyeing control network and the environmental protection equipment.

[0015] Based on all pollutants generated in the production control process, multiple control levels are divided through clustering methods and statistical methods. The control weights of the basic printing and dyeing control network are generated according to the control level and production control process to obtain a preliminary printing and dyeing control network. This solution can realize data quantification and generate the corresponding printing and dyeing control network based on the existing process.

Based on the above content, the control data can be intelligently analyzed through a deep learning algorithm to avoid some unexpected control signals of the equipment causing errors in the coordinated control of the environmental protection equipment. At the same time, intelligent monitoring can still be achieved when the production link is optimized to reduce the cost of subsequent data re-analysis. At the same time, the frequency of environmental protection equipment can be automatically and intelligently monitored, processed and adjusted based on different data in different scenarios to minimize energy consumption and realize the coordinated control of the start and stop of intelligent environmental protection equipment that produces different pollutants in different production links. At the same time, the frequency of intelligent monitoring and processing can be adjusted based on existing data to realize the coordinated control of the monitoring and processing of the environmental protection equipment itself in different scenarios.

Another method of digitizing the printing and dyeing production process was used as a data reference basis, and intelligent data monitoring was performed through a deep learning model, so that when problems occur, the production control network can be self-calibrated with the help of the timeline function, thereby improving the robustness and accuracy of the environmental protection equipment coordinated control system; The key control parameter association module of printing and dyeing obtains the equipment control parameters of the production control process, maps the equipment control parameters to the control weights of the preliminary printing and dyeing control network, and associates the control parameters of various environmental protection equipment according to the control weights of the preliminary printing and dyeing control network; and initializes the control parameters of the environmental protection equipment; the specific process is: according to the control weights, the corresponding environmental protection equipment is associated, the equipment control parameters generate equipment control nodes and connect the environmental protection equipment to generate control weights, and the initialization of the control parameters of the environmental protection equipment is completed; the initialization value of the control weight is 1; in order to ensure accuracy in the initial stage, all equipment control nodes in each link are associated with environmental protection equipment, and then updated after the model is intelligently analyzed; Based on the digitized equipment parameters of the entire production process, as the nodes of the entire printing and dyeing control network, the environmental protection equipment control parameters are connected through these nodes, and the control data of the environmental protection equipment can be quantified, which is convenient for subsequent collaborative control processing. At the same time, the quantified data is initialized, which is also convenient for more accurate collaborative control in different scenarios, ensuring that the environmental protection equipment control can play a corresponding efficient result in the corresponding environment, so as to improve the efficiency and accuracy of the collaborative control of environmental protection equipment; An environmental protection equipment control parameter weight update module, which analyzes each of the equipment control parameters according to the printing and dyeing control parameter monitoring model, updates the environmental protection equipment control parameters according to the equipment control parameters, generates a parameter printing and dyeing control network and controls the monitoring and processing frequency of the environmental protection equipment; Furthermore, the printing and dyeing control parameter monitoring model includes an equipment control parameter input processing unit, a control parameter abnormality identification unit, a control parameter abnormality correction unit and a control parameter mode output unit.
