The connection state between the pipeline connecting elbow 5 and the directly connected pipeline 4 can be finely adjusted through the elbow adjusting support 7, the adjusting method is that the connecting angle of the pipeline connecting elbow 5 is accurately adjusted by rotating the screw rod in the elbow adjusting support 7, and the angle fine adjustment of 0-20 degrees can be supported at present, so that the adjustment of the curvature is realized.
As shown in FIG. 2, the intelligent tobacco shred brand exchange station in the embodiment uses a piping prediction system GXYC-01, a control decision system KZJC-01 and an input/output detection system CRJC-01 developed by Siemens WinCC besides a mechanical structure; their connection and function are described in detail below.
The method comprises the steps that firstly, a pipeline system prediction system GXYC-01 is combined with a big data analysis mining technology and a machine learning technology to analyze and research process parameters, control parameters, equipment parameters, environment parameters and the like involved in the tobacco shred grade exchange process as objects, and a grade exchange pipeline system prediction model is formed. The method comprises the steps of analyzing and excavating historical data distributed by a large number of tobacco shred brand exchange pipe systems, and researching, simulating and abstracting the use distribution condition of pipelines and brand interface exchange condition related in the process of tobacco shred feeding production as objects to form a prediction model of the tobacco shred brand exchange pipe systems. The model is not invariable, but is dynamically and continuously updated, historical data of the current production is used as sample data for analysis, and a prediction model suitable for the current production is formed. The model can be guaranteed to change along with changes of time, production environment, working conditions and the like, and accurate prediction of current production is guaranteed. The piping prediction process encompasses: sample data analysis, sample data preprocessing, model selection, model construction, model verification and continuous optimization of a prediction model.
Secondly, a control decision system KZJC-01 mainly aims at the distribution control of wire feeding and wire tube, and is implemented by three stages:
first is validation of the control decision. On the basis of the existing tobacco shred grade exchange system, operators with abundant experience manually carry out the distribution control of the tobacco shred pipes according to the requirements of tobacco shred processes with different grades to obtain a manual tobacco shred pipe distribution control decision model. On the basis, data information such as the occupation condition of an input/output port of the tobacco pipe, the tobacco exchange efficiency, the service condition of the tobacco outlet pipe and the like in the tobacco grade exchange process is analyzed, the input-output relation of the tobacco grade exchange process is finally established through continuous optimization and iteration, and the acquired data is filtered and smoothed. And then, a silk tube distribution control decision table is obtained by deeply learning the data. The decision table is utilized to synchronously generate a tobacco shred grade exchange automatic control strategy, the two control strategies are subjected to deviation calculation and the similarity degree of the two control strategies is counted, and the final aim is to adjust the weight or parameters of automatic control so that the deviation between the automatic control and manual control approaches zero.
And then, on the basis of the current stable wire tube distribution control decision, observing the change and fluctuation conditions of the wire tube distribution control decision by changing environmental parameters. By superimposing different environmental parameters into the system, it is continuously recorded, analyzed and corrected. The corresponding relation of the influence degrees of different environments on the wire tube distribution control decision can be obtained under the same stable system. And performing machine learning on the corresponding relation to obtain a tobacco shred grade exchange process input-output corresponding relation table, optimizing the table, and feeding the table back to an MES (manufacturing execution system) system to be used as a basis for a next-stage intelligent control decision.
And finally, by learning the input-output relation of the wire tube distribution control decision table, introducing the previously completed prediction model and the wire tube distribution control decision table as a 'black box' system into a control environment, and by a large amount of data training and iteration, enabling the intelligent control decision system to establish a multi-input-multi-output control decision relation so as to replace manual control, directly sending a control instruction to each actuator, directly converting control information into the action of the actuator, and directly completing the overall intelligent control. The process can completely break away from the framework of artificial cut tobacco grade distribution control, and the optimal rule of the thread pipe distribution control can be directly found out from various input and output information through deep learning of a computer.
And thirdly, an input/output interface of the input/output detection system CRJC-01 is embedded with an RFID reader-writer and a state indication screen, so that whether the connection of the input/output pipeline is correct and reliable can be verified. The connection state information of the wire feeding pipeline is directly transmitted to each wire feeding pipeline interface through a field bus. And the joints of the wire feeding pipelines are all provided with a state indicating screen, so that the pipeline connection condition can be displayed in real time. If the assigned production task is matched with the pipeline input and output interface, the pipeline connection is successfully verified, and the system can allow the subsequent work flow. If the verification fails, the system prohibits the subsequent flow and feeds back the matching result of each wire feeding pipeline to the MES system in real time.

Then automatically judging whether the input and output interface is connected correctly or not and automatically checking whether the pipeline is connected smoothly and correctly or not. If the input and output interfaces are detected to be connected correctly and the pipe system is connected smoothly, the tobacco feeding valve is opened to start production, and the tobacco shreds can pass normally; once an incorrect or missing pipeline connection is detected, namely the connection is wrong, the corresponding valve is immediately disabled, starting is forbidden, the error is transmitted back to recheck through a field bus, or the error is transmitted to the PLC main control equipment, all equipment of the tobacco shred brand exchange station is monitored and integrated by the upper computer, and meanwhile, the system has the data acquisition and control functions of equipment and process parameters, provides data for a factory information system, and receives the production task of the factory information system and issues the process parameters.
