Description

Technical Field

[0001] The present invention relates to the technical field of industrial coding control, and particularly relates to an industrial control system for flow tracing management in process industry. Background Art

[0002] Product identification and traceability generally include the identification and traceability of raw materials, work-in-progress, and finished products of a product, and are mainly applied to quality control, quality traceability, factory informatization applications, etc. in the production process. Generally, raw materials and finished products can be used to identify and trace materials through methods such as coding, labeling, FRID, etc.

[0003] In the production process of process industry, generally one or more raw materials are continuously fed into the production line after batching, mixing, or other processing in the feeding unit. Each work-in-progress formed by each feeding is called a production flow. The production flow enters the processing production line for continuous production and flows out in the form of a product from the end of the production line. Since each feeding forms a work-in-progress and is processed through each processing unit, it is also necessary to perform production management, quality management, and traceability management on the production process of each work-in-progress, and it is necessary to identify and trace each work-in-progress (production flow) to achieve transparent management of the work-in-progress production process in the factory. For abnormal work-in-progress, it is necessary to trace online. If necessary, the abnormal work-in-progress is removed from the production line through tracing to prevent unqualified products from entering the next processing unit. For each finished product produced, it is also necessary to trace the production and processing process data of the production flow for quality traceability, product recall, etc. Since the raw materials in the process industry enter the production line and the work-in-progress is in a continuous state in the continuous processing unit, when the work-in-progress exists in the form of liquid, powder, granule, block, etc., it is impossible to identify and trace it through methods such as coding, labeling, FRID, etc. For the identification and traceability methods of such work-in-progress, for the production line in the batch production process, the batch production line generally produces in small batches and intermittently. The existing technology mainly uses batch control (Batch) industrial control software and uses the batch report function to manage the production data of work-in-progress for each intermittent batch product. However, only the production information of the corresponding finished product batch is recorded in the batch report, and there is no production flow information of the finished product and work-in-progress. Summary of the Invention

[0035] The present invention will be further described in detail below in conjunction with test examples and specific implementation manners. However, it should not be understood that the scope of the above-mentioned subject matter of the present invention is limited to the following embodiments, and all technologies implemented based on the content of the present invention belong to the scope of the present invention.

[0036] Embodiment 1

[0037] Figure 1 Shows the structural block diagram of the industrial control system for flow tracing management in the process industry of an exemplary embodiment of the present invention, including:

[0038] A signal acquisition unit, a coding unit, and a queuing push-in / push-out unit that are signal-connected to the production equipment in each production link;

[0039] The signal acquisition unit is used to collect the feeding state signal and the discharging state signal of the production equipment it is connected to, and send a first trigger signal to the coding unit when receiving the feeding state signal of the production equipment; and, send a second trigger signal to the queuing push-in / push-out unit when receiving the discharging state signal of the production equipment;

[0040] The counting and coding unit is used to increment the count of the production equipment connected to the signal acquisition unit by one when receiving the first trigger signal from a certain signal acquisition unit, generate a flow code for the production equipment according to the counting result, and transmit the flow code of the production equipment to the queuing push-in / push-out unit; the queuing push-in / push-out unit stores the received flow code in the storage queue corresponding to the production equipment;

[0041] The queuing push-in / push-out unit takes out the bottommost flow code in the storage queue corresponding to the production equipment based on the second trigger signal.

[0042] Specifically, the data collected by the signal acquisition unit can complete logical operations on the industrial control computer or can be completed by the edge computing layer. That is, the functions of the coding unit and the queuing push-in / push-out unit can be implemented by the industrial control computer or the edge computing layer.

[0043] In the production process of process industry, the industrial control system is generally used to control the production process of production devices. In the production process of process industry, generally one or more raw materials enter the production line through the feeding unit. In the feeding unit, batching, mixing or other processing is generally carried out before entering the production line. Each work-in-progress formed by each feeding is called a production flow. The production flow enters the processing production line for continuous production and flows out in the form of products from the end of the production line. In the production process, a serial number is generally used to identify and trace each work-in-progress. The present invention uses an industrial control system to automatically generate a corresponding production serial number for each work-in-progress in the process industry for identification, and automatically tracks the flow of the work-in-progress with this production serial number in the process device until the work-in-progress with this production serial number flows out at the end of the production line to form a finished product. The upper computer display screen of the industrial control system is used to display the production process in real time. The specific technical solution is as follows:

[0044] First, the method for dividing the production units of the production line is analyzed. According to the characteristics of the production process equipment in the process industry, the entire production line is divided into several independent production units: the first production unit (hereinafter referred to as UNIT_1 unit), the second production unit (hereinafter referred to as UNIT_2 unit), until the last production unit (hereinafter referred to as UNIT_X unit), etc. The number of work-in-progress flows in each production unit is 1 or an integer multiple N. The production units with an integer multiple N serial numbers are divided into first-in-first-out flow production units and mixed batch production units; the numbering method of the flow code is determined according to the division result. In this embodiment, the flow code (at least including the serial number and the production equipment serial number) is composed of a string. The serial number string contains information such as the order number, production date, production unit number (UNIT_1 unit - UNIT_X), serial number of the flow, etc., and at least includes the order number, production unit number (UNIT_1 unit - UNIT_X), serial number of the flow, etc., as Figure 2 shown, where the serial number of the flow adopts an automatically incrementing method.

[0045] Figure 3The single production unit identification and tracing method of the industrial control system of the exemplary embodiment of the present invention is shown. The detection signal of each production unit of the industrial control system includes at least the signals of feeding permission, discharging permission and discharging end. When the production line is feeding raw materials, after the industrial control system detects the feeding permission signal in the UNIT_1 unit, a work-in-progress is formed when the raw materials enter the UNIT_1 unit and the work-in-progress is finished. According to the numbering method of the production serial number, a production serial number is automatically generated to identify the work-in-progress. The industrial control system stores the formed production serial number in the storage queue Queue1, and the work-in-progress is batched, mixed or processed in the UNIT_1 unit. When the signal detection unit detects that the UNIT_1 unit sends a discharging permission signal after the processing is completed and the UNIT_2 unit sends a feeding permission signal, the second production unit UNIT_2 unit starts feeding, and the work-in-progress enters the UNIT_2 unit. The work-in-progress generated by the UNIT_1 unit begins to enter the UNIT_2 unit. When the discharging end information of the UNIT_1 unit is detected, Queue1 takes out the production serial number, and the raw material feeding and queue processing enter the next cycle. The work-in-progress with this production serial number enters the UNIT_2 unit and ends, generating the production serial number of the work-in-progress mark UNIT_2 unit. The production serial number is stored in Queue2, and the work-in-progress with this production serial number is processed in the UNIT_2 unit. When the processing of the UNIT_2 unit is completed and a discharge permission signal is issued, and the UNIT_2 unit issues a feed permission signal, the work-in-progress enters the UNIT_3 unit, and the work-in-progress enters the next cycle. When it is detected that the UNIT_2 unit issues a discharge end signal, QueueX takes out the production serial number, and the UNIT_2 unit enters the next cycle. The above method is followed until the UNIT_X unit is a finished product unit, and the production serial number forms a product that flows out of the production line. The difference between the finished product unit and the intermediate unit is that the discharge end signal will not be passed down.

[0046] Figure 4The control method of the first-in-first-out (FIFO) flow production unit of the industrial control system according to an exemplary embodiment of the present invention is shown. The FIFO unit is generally a uniform production unit, and a timer is used to trace the production serial number of the work-in-progress. The detection signals of the industrial control system for each FIFO flow unit at least include started, feeding allowed, discharging allowed, discharging ended, and timer reached. When raw materials are fed into the production line, after the industrial control system detects the feeding allowed signal in the UNIT_1 unit, a work-in-progress is formed when the raw materials enter the UNIT_1 unit. A production serial number is automatically generated according to the numbering method of the production serial number to identify the work-in-progress. The industrial control system stores the formed production serial number in the storage queue Queue1, and at the same time starts a timer for each corresponding incoming work-in-progress. The work-in-progress is proportioned, mixed, or processed in the UNIT_1 unit. When a timer in the UNIT_1 unit reaches, a discharging allowed signal is sent to the next unit, and the work-in-progress is transferred to the next unit UNIT_2 until after discharging ends. The UNIT_1 unit takes out the serial number of the first-in Queue1. This process repeats. When the FIFO production unit NUIT_2 detects the discharging allowed signal from the previous unit UNIT_1 and the feeding allowed signal of its own unit UNIT_1, the production unit UNIT_2 starts to feed, and the work-in-progress enters the UNIT_2 unit. When the previous unit NUIT_1 sends a discharging ended signal once, the UNIT_2 unit automatically generates a production serial number according to the numbering method of the production serial number to identify the work-in-progress. The industrial control system stores the formed production serial number in the storage queue Queue2, and at the same time starts a timer for a corresponding work-in-progress. The work-in-progress starts to be processed in the UNIT_2 unit. When a timer in the UNIT_2 unit reaches, a discharging allowed signal is sent to the next unit UNIT_X. This continues until the finished product packaging unit. As Figure 4 shown, according to the above method, until the production unit is a non-FIFO unit or a finished product unit, the production serial number is transmitted in a single form, and the product flows out of the production line.

[0047] Figure 5A control method for a mixed-batch flow production unit of an industrial control system according to an exemplary embodiment of the present invention is shown. The mixed-batch flow unit stores and mixes the N flows of an order in one unit and then continues to discharge the mixed entire order flow to subsequent production units. The number of flows that have reached the mixed-batch unit can be traced by using a counter. The industrial control system sets detection signals for each mixed-batch flow production unit. The detection signals at least include started, feeding allowed, discharging allowed, discharging ended, and counter reached. When any mixed-batch unit UNIT_Y detects the discharging-ended detection signal of the previous non-mixed-batch unit UNIT_Y-1, the counter is incremented by 1 until the counter reaches the number of flows N of an order. At this time, all flows of an order have entered the mixed-batch unit, and subsequent materials are identified by the order number. The industrial control system stores the order numbers to which the N flow numbers belong in the storage unit QueueY. The work-in-progress starts to be processed in the UNIT_Y unit. When it is detected that the discharging-allowed detection signal of this unit NUIT_Y and the feeding-allowed detection signal of the next unit UNIT_Y+1 are satisfied, this unit starts to discharge until the discharging-ended detection signal of this unit is detected, and then the order number is taken out from the access unit QueueY of this unit. Similarly, when the next unit UNIT_Y+1 detects the discharging-ended signal of this unit UNIT_Y, the industrial control system stores the order numbers to which the N flow numbers belong in the storage unit QueueY+1. The work-in-progress starts to be processed in the UNIT_Y+1 unit until the product is formed in the finished product unit and flows out of the production line. The control system realizes the identification and tracing method for the mixed-batch process of each production flow according to the detection signals of each production unit, which at least include signals such as feeding allowed, discharging allowed, discharging ended, and counter reached. The industrial control system sets a storage queue for each mixed-batch production unit. When it is detected that the discharging-allowed signal from the previous unit and the feeding-allowed signal of this unit are satisfied, this unit starts to feed. When the discharging-ended signal of the previous unit is detected, the feeding of this unit is completed. At this time, the flow counter of this mixed-batch unit is triggered once, and at the same time, it is judged whether the accumulated value of the counter is greater than or equal to the maximum flow value of this production order. If not, the production flows that have entered are continuously processed in a loop and the production flows from the previous unit are continuously received. When it is detected that the accumulated value of the counter is greater than or equal to the maximum flow value of this production order, the production order number and the mixed-batch unit number of this unit are combined into an order string, and this order number is stored in the queue. When it is detected that the discharging of this unit is allowed and the feeding-allowed signal of the subsequent unit is detected, all materials of this order start to be discharged. When the discharging-ended signal of this unit is detected, the order number in the storage queue is removed, and at this time, the production of this production order ends in this mixed-batch unit.

[0048] Furthermore, the industrial control system stores the in-process flow of each production unit using a queue calculation method. The industrial control system stores the in-process flow of each production unit using a queue calculation method. Each storage queue consists of N data areas (stacks), and each data area can store a string; when the queue receives a storage signal, all non-empty areas in the queue move down one position as a whole; at this time, the first position is an empty area, and the string received when the current storage signal is received is stored in the first area; when the queue receives a removal signal, scan the first non-empty data area from bottom to top in the queue and remove the data in this area; the control system sets a data queue for each production unit to store serial number information including the serial number string, including the storage and retrieval operations of the queue, and adopts the first-in, first-out principle. The industrial control system also records the storage time and retrieval time of the serial number through the historical data server. The first-in, first-out queue control method is that when a control signal for storage is detected, read the synthesized serial number string and store it in a string temporary variable. At the same time, move all non-empty character variables in the queue down one position as a whole. The vacated topmost position becomes an empty character, and store the value of the newly read string temporary variable in the topmost position; when a control signal for retrieval is detected, assign the bottommost non-empty character to be empty, and then the pop is completed. The upper computer interface of the industrial control system can implement the method of displaying the identified in-process production serial number, and can realize the visual dynamic display of the production line materials. The display method can display the serial number, the time of serial number pressing, the time of popping, etc. of the production unit on the production unit of the process flow interface, or can use a separate interface to display the serial number information of each device.

[0049] Through the above method, the present invention can achieve the identification and tracking of work-in-progress, better assist in the product quality traceability management process, and effectively realize the supervision and control of all links of product quality. Applying the work-in-progress production serial number identification provided by the present invention to the quality management application of production process management, when sampling and inspecting the work-in-progress during the production process, the production serial number of the sample can be determined by combining the sampling point and sampling time with the production serial identification of the present invention. When the inspection result comes out, if there is a product quality problem, the production serial number can be directly found according to the serial number, and the work-in-progress with this production serial number can be removed from the production line or from the finished products, accurately determining the production serial number with quality problems, and preventing qualified products from being removed from the production line or from the finished products, resulting in greater economic losses. Adding the work-in-progress production serial number identification provided by the present invention to the product label and applying it to product quality traceability management, when the product is submitted to the user, if the user finds a quality problem during the use of the product, the product with this production serial number can be quickly traced according to the production serial number marked on the product, preventing unqualified products from causing greater losses to the user. In industries such as food, medicine, and automobiles, which involve personal safety and are prone to cause larger quality accidents, it is applied to accurate product recall to prevent greater losses to the user. Applying the work-in-progress production serial number identification provided by the present invention to industrial big data analysis, the serial number identification of the work-in-progress can be used as a keyword to extract data such as production process data, quality inspection data, and formula data. About 80% of the work in industrial big data analysis is mainly used for data collation. Using the work-in-progress production serial number identification as a keyword directly associates different types of data related to the production serial number, which can greatly save the workload of data collation in industrial big data and improve the data collation efficiency of industrial big data analysis by 60%. Applying the work-in-progress production serial number identification provided by the present invention to industrial automation control applications, the work-in-progress production serial number identification can be used in combination with on-line quality inspection instruments and work-in-progress removal devices. When the on-line quality inspection instrument detects that the work-in-progress with this production serial number is unqualified, the industrial automation control system issues an instruction to the work-in-progress removal device to directly remove the work-in-progress with this production serial number from the production line, preventing unqualified products from flowing into the next process and causing processing waste, while improving the automation level of the production line and production efficiency.

When mixing for the second time, according to the production serial number generation method, the serial number is incremented automatically, and the production serial number is: TYLD20200301-GH-02. And so on, until the total output of this batch is 20 production flows, and the last production serial number is: TYLD20200301-GH-20.
