Abstract
Description
Technical Field
[0001] The present invention relates to the field of industrial automation, and in particular to a CIP system and method based on an order mode. Background Art
[0002] CIP (cleaning in place) technology refers to cleaning in a closed loop without disassembling or opening the equipment. It can be used in food and beverage production enterprises with a high degree of mechanization, such as beverages, dairy products, and alcoholic beverages. The system cleaning process is achieved through the configuration of acids, alkalis, hot water, circulating pumps, and pipeline systems. The main factors affecting CIP are the flow rate, temperature, concentration, and cleaning time of the cleaning fluid. In the actual application of CIP, the key influencing factor of the cleaning effect, effective time, has been gradually proposed. Different from the cleaning time, the effective time refers to the cleaning time when the temperature and concentration of the cleaning fluid meet the requirements.
[0003] From the perspective of the design and development stage of the CIP system, the CIP system can be divided into the manual operation stage based on electrical control and the central control stage based on automatic control. The operation process of the manual operation CIP system relies on human judgment, the process relies on manual recording, the cleaning results vary from person to person, and the post-analysis relies on experience. Without data support, it is impossible to summarize and optimize the CIP process experience. The central control CIP system consists of a PLC (programmable logic controller) system, a central control (human-machine interface) system, and a CIP body. Compared with the manual operation stage, the cleaning process is automatically completed by the machine, guaranteed by sensors and set programs, and the time is controlled according to the CIP standard process, so the cleaning results can basically be guaranteed to be consistent.
[0004] However, in actual production activities, it was found that there were loopholes in the CIP activity management system of the central control CIP system. When performing CIP activities in accordance with regulations, the operator inputs the CIP parameters of the corresponding circuit in the central control system according to the "Cleaning Parameter List", and another operator checks and verifies. After the operator completes the execution, he manually records the completion status and returns the CIP activity record sheet to the manager. However, it is difficult for the manager to ensure whether the operator performs in accordance with the regulations and whether the parameters are entered correctly. As a result, the actual implementation of CIP activities is difficult to guarantee, which may result in incomplete cleaning, which in turn may cause residual impurities to be mixed into the product, or bacteria to be incompletely cleaned, causing food safety accidents.
[0005] On the other hand, the CIP process of the central control CIP system is not transparent, and the massive data collected by the PLC unit is not analyzed and utilized. The alarm information is not classified, and only a small part of the information collected by the sensor is displayed on the central control interface. When a problem occurs, the operator does not know which sensor and which part has an error or alarm. Therefore, the technicians cannot effectively track and analyze the CIP system problems. The post-analysis relies on experience and judgment, and cannot summarize and optimize according to the operation situation. Summary of the invention
[0006] The present invention provides a CIP system and method based on an order mode, which solves the CIP management process loophole problem and the CIP activity process opacity problem existing in the CIP system based on automatic control, realizes the advantages of error-free CIP parameters and iterative optimization of CIP process parameters through data analysis.

[0018] CIPM={[a n ,(l 1 ,t 1 ,),(l 2 ,t 2 ,),…,(l n ,t n ,)]}<P|K|C|L>
[0019] In the formula, CIPM represents the CIP process step standard document, n represents the total number of steps in the cleaning process, a n Indicates the CIP formula adopted in step n, l n represents the production line loop included in step n, t n Indicates the cleaning time of step n.<P|K|C|L> Indicates the conditions for order generation, where P represents the production line planned for cleaning; K represents the items produced by the production line; C represents the order type; and L represents the order category.

[0021] The items represent the flavors produced by the production line planned for cleaning; the order category refers to the cleaning method; and the order types include test orders and production orders.
[0022] Preferably, the specific process of the order execution module monitoring the CIP equipment execution process is:
[0023] After receiving the CIP device execution information uploaded by PLC unit 2, the CIP device execution information is first compared in real time with the data in the sensor signal classification file in the selected standard CIP order. If they are the same, no processing is performed. If they are different, they need to be compared with the alarm information classification file to determine whether an alarm is required. If no alarm is required, it is ignored. If an alarm is required, an alarm operation is performed and the alarm information is sent to the PLC unit to pause the CIP device, thereby realizing the monitoring of the entire CIP device execution process.
[0024] Preferably, all relevant information of the CIP order includes the CIP execution time, the operator, the production line where the CIP is performed, the sensor signal and the alarm information.

The order execution module sends the real-time operation data to the order saving module for storage, while comparing the real-time operation data with the data in the sensor signal classification file of the selected standard CIP order, and uses the alarm information classification file to monitor the operation of the CIP equipment. If an alarm message appears in the order management unit, the PLC unit will stop the CIP equipment loop where the alarm message appears, and will not enter the next step of the CIP activity; wait for the operator to confirm the alarm message and perform manual intervention before terminating the current CIP order. If you need to continue the current CIP activity, you need to regenerate the CIP order; only after a CIP order is completed can the next CIP order be executed, otherwise the CIP order will continue to occupy the PLC unit.

[0041] The present invention establishes an order management unit, and all CIP activities compare the various data information automatically collected by the PLC unit with the standard setting data in the standard CIP model in real time. When an error occurs, an alarm is immediately given, and program execution is suspended to wait for manual intervention and correction, thereby achieving error-free execution of CIP activities.
[0042] The present invention establishes an order management unit to monitor and display various data information of CIP activities in real time, and through the "order-central control interlocking" function, realizes "no order, no cleaning", "cleaning process is executed according to the order" and "cleaning process is not completed, the order is not ended", ensuring that all CIP activity processes are fully transparent and realizing error-free CIP activity management.

[0051] The exemplary embodiments, features and aspects of the present invention will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.
[0052] The traditional CIP system consists of a PLC unit and CIP equipment. When a cleaning task needs to be performed, parameters need to be set in the PLC unit. However, the PLC unit does not have a management function, and it is impossible to track whether the specific operation is performed in accordance with the regulations and whether the parameter input is correct. The present invention adds an order management unit to the existing CIP system to realize CIP activity management based on the order mode. There are M production lines in a factory, and each in-situ cleaning includes m production lines, where m is less than or equal to M and is a positive integer. The in-situ cleaning of a production line is defined as a CIP activity, and a CIP order includes m CIP activities in this in-situ cleaning. The order management unit 1 enables the CIP equipment to work only according to the pre-stored CIP order, and monitors and saves the execution of each CIP order, and saves all executed CIP orders according to the execution time. Each saved CIP order contains all the information of each CIP activity, including CIP time, operator, production line for CIP, sensor signal, alarm information and other order-related information. CIP management based on the order model realizes the recording of information of the entire CIP process, and achieves the goal of making the CIP execution process fully transparent, traceable, and statistically analyzable.
[0053] To illustrate the technical solution of the present invention in detail, the following will be described in detail with reference to the accompanying drawings.
[0054] like Figure 1 As shown, to achieve the above-mentioned purpose, the present invention proposes a CIP system based on an order mode, comprising an order management unit 1, a PLC unit 2 and a CIP (cleaning in place) device 3;
[0055] The order management unit 1 is used to manage CIP data in an order-based manner, and has data collection, statistics and analysis functions, including an order generation module 11, an order storage module 12, an order execution module 14, an order query module 13, a standard CIP order management module 15 and a human-computer interaction module 16. The order management unit 1 manages CIP orders. First, the human-computer interaction module 16 selects a suitable CIP order from the standard CIP order management module 15 according to different cleaning conditions, and generates a CIP order in the order generation module 11. Each CIP order is sent to the PLC unit 2 through the order execution module 14, and each CIP order is saved in the order storage module 12, and can be queried at any time through the order query module 13.
[0056] The standard CIP order management module 15 is the basic database of the order management unit 1, which stores all standard CIP orders for different cleaning conditions. The standard CIP order refers to an order that conforms to the CIP order model. The CIP order model includes three files: an alarm information classification file, a sensor signal classification file, and a CIP process step standard file; wherein the alarm information classification file is used to set the alarm threshold of the sensor signal when executing the corresponding CIP order, and the sensor signal classification file is used to set the expected value of the sensor when executing the corresponding CIP order. The CIP process step standard file includes a loop list, a CIP recipe, and a step list, which can be represented by the following model:
[0057] CIPM={[a n ,(l 1 ,t 1 ,),(l 2 ,t 2 ,),…,(l n ,t n ,)]} <P|K|C|L>
[0058] In the formula, CIPM represents the CIP process step standard document, n represents the total number of steps in the cleaning process, a n Indicates the CIP formula adopted in step n, l n represents the production line loop included in step n, t n Indicates the cleaning time of step n. <P|K|C|L> indicates the conditions for order generation, where P indicates the production line planned for cleaning; K indicates the items produced by the production line; C indicates the order type; and L indicates the order category.
[0059] Different CIP orders are required for different cleaning requirements. If parameter setting is required for each cleaning, it will lead to huge workload and easy errors. The parameters in the standard CIP order are pre-packaged and are not allowed to be modified. The standard CIP order management module 15 directly provides the standard CIP order, thereby reducing the error rate when setting the CIP parameters. If the process parameters in the standard file of the CIP process step need to be optimized, the process parameters in the standard CIP order can be directly modified and saved by a technician with modification authority, and the parameter modification and execution are isolated, and there is no need to change the PLC unit, making the data management of the CIP system convenient.
[0060] The order generation module 11 is used to generate a CIP order. After selecting a standard CIP order from the standard CIP order management module 15 according to the current cleaning conditions, a CIP order can be directly generated. The cleaning conditions include the production line, items, order categories and order types planned to be cleaned. The items represent the flavors produced by the production line planned to be cleaned, such as lemon, peach, mango, etc. The order categories include three-stage washing, five-stage washing, three-stage washing + chemical disinfection and other cleaning methods. The order types include test orders and production orders. The cleaning conditions are obtained from the human-computer interaction module 16.
[0061] The order execution module 14 receives the generated CIP order from the order generation module 11, sends the process parameters in the CIP order to the PLC unit 2, receives the CIP equipment execution information uploaded by the PLC unit 2, monitors the CIP equipment execution process, and sends the executed CIP order and the uploaded CIP equipment execution information to the order storage module 12 and displays them in the human-computer interaction module 16. The specific process of the order execution module 14 monitoring the CIP equipment execution process is as follows: after receiving the CIP equipment execution information uploaded by the PLC unit 2, the CIP equipment execution information is first compared with the data in the sensor signal classification file in the selected standard CIP order in real time. If they are the same, no processing is performed. If they are different, they need to be compared with the alarm information classification file to determine whether an alarm is required. If no alarm is required, it is ignored. If an alarm is required, an alarm operation is performed, and the alarm information is sent to the PLC unit to suspend the CIP equipment, so as to realize the monitoring of the entire execution process of the CIP equipment.
[0062] The order saving module 12 is used to save the CIP order sent by the order execution module 14 and all relevant information of the CIP order, such as CIP time, operators, production lines for CIP, sensor signals, alarm information, etc.
[0063] The order query module 13 is used to query CIP order information. According to the query information obtained from the human-computer interaction module 16 , the order storage module 12 retrieves the CIP order information, and then sends the queried CIP order information to the human-computer interaction module 16 .
[0064] The human-computer interaction module 16 is the entrance to control the order management unit 1, and integrates various operation interfaces and query result display interfaces of the order management unit 1, including personnel login, order operation, historical order information analysis, alarm, equipment status, etc. Figure 3 It is the human-machine interaction interface of the traditional CIP system; Figure 4 It is the human-computer interaction module interface of the present invention; Figure 5 The order execution interface of the present invention; Figure 6 It is the alarm information interface of the order execution module of the present invention; Figure 7This is the order query module interface of the present invention; the above interface is only a schematic display and does not mean that this application only has these few interfaces.
[0065] The CIP equipment 3 is used to clean the equipment in the production line, and includes a cleaning device 31 and N sensors 32, where N is a positive integer greater than 2. The cleaning device 31 includes a pipeline, a tank, a pump or a valve, etc. The CIP equipment 3 uses an existing CIP equipment. The sensors are used to monitor signals such as temperature, time, pressure and concentration.
[0066] The PLC unit 2 is a control system for controlling the operation of the CIP equipment 3, including the opening and closing of pumps and valves, and the signal collection of N sensors arranged in pipes, tanks and other equipment. The control parameters of the PLC unit 2 are obtained from the order execution module 14 of the order management unit 1, and the received sensor acquisition signals are uploaded to the order execution module 14 of the order management unit 1. The PLC unit 2 can only be started through the order management unit 1. If the order management unit 1 does not provide an order, the CIP equipment cannot be directly started through the PLC unit 2, that is, the method of starting the CIP equipment through the PLC unit in the prior art is cancelled.
[0067] The present invention also provides a method for using a CIP system based on an order model, such as Figure 2 As shown, the following steps are included:
[0068] S1, generating a CIP order in the order management unit, including the following steps:
[0069] S11, after selecting to add a CIP order in the human-computer interaction module in the order management unit, select the production line, item, order category and order type.
[0070] S12, after clicking OK, the order management unit selects a standard CIP order from the standard CIP order management module according to the combined screening conditions of production line, item, order category and order type, and obtains CIP parameters according to the standard CIP order.
[0071] S13, after checking the corresponding CIP parameters of the standard CIP order, click the confirmation button to generate the CIP order and send the CIP order to the order execution module. There are the following advantages in generating CIP orders in this way: first, using a fixed standard CIP order, the operator does not need to set parameters, which can prevent parameter errors; second, the order is generated only after confirmation, which is equivalent to a second confirmation of the parameters, further increasing reliability.
[0072] S2, the order execution module sends the CIP order to the order storage module and the PLC unit respectively.
[0073] The order execution module sends the CIP order to the order saving module and the PLC unit respectively. After receiving the order, the order saving module saves the order. After receiving the order, the PLC unit obtains the CIP parameters from the CIP order and controls the operation of the CIP equipment.
[0074] S3, CIP equipment operation monitoring.
[0075] The operation process of CIP equipment is carried out completely in accordance with CIP orders.
[0076] When the CIP equipment is running, the real-time operation data of the CIP equipment is collected through the sensor of the CIP equipment, and the real-time operation data is sent to the PLC unit. The PLC unit then sends the real-time operation data to the order execution module in the order management unit. The order execution module sends the real-time operation data to the order saving module for saving and displaying in the human-computer interaction module, and compares the real-time operation data with the data in the sensor signal classification file of the selected standard CIP order, and uses the alarm information classification file to monitor the operation of the CIP equipment. If an alarm message appears in the order management unit, the PLC unit will stop the CIP equipment loop where the alarm message appears, and will not enter the next step of the CIP activity, that is, the next step in the CIP order. Wait for the operator to confirm the alarm message and intervene manually before ending the current CIP order. If you want to continue the current CIP activity, you need to regenerate the CIP order. Only after a CIP order is completed can the next CIP order be executed, otherwise the CIP order will continue to occupy the PLC unit. This setting ensures the cleaning effect and improves safety.
[0077] S4, according to the CIP process step standard document, complete the cleaning of the circuit in sequence.
[0078] S5. After the CIP order is executed, the CIP order and real-time operation data will be saved in the order saving module. The order query module can query and count the executed historical CIP orders.
[0079] S6, through statistical analysis of the operating data, if it is found that the CIP order parameters have more reasonable settings, the parameters in the standard CIP order can be modified to optimize the CIP system. The parameters in the standard CIP order must be modified by personnel with modification authority.
[0080] The order management unit 1 in the present invention has the function of monitoring the entire CIP process, which improves the operational safety and reduces the CIP failure rate compared with the traditional CIP system. The human-computer interaction module 16 upgrades the CIP operation to a windowed menu type, which is executed according to the prompt process without memorizing the operation steps; the order generation module 11 generates a CIP order according to the standard CIP model, and the CIP order can only be issued to the order execution module 14 after secondary confirmation; the standard CIP order management module 15 contains all the standard CIP models to prevent human errors in the setting of CIP process parameters; the order execution module 14 monitors the CIP execution process, and once the parameters in the execution of a certain CIP activity exceed the threshold set by the standard CIP model, the CIP activity stop signal is immediately sent to the PLC unit 2, and the alarm information is displayed in the human-computer interaction module 16; the order storage module 12 records all information generated by the order management unit 1, including the generation of orders, order execution status, alarm information, etc.; the order query module 13 can count historical order information, analyze order execution efficiency, and provide data support for the improvement of CIP process through intuitive display in the form of line charts, pie charts, etc.
[0081] The embodiments described above are only descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.

6. A method for using the CIP system based on the order model as claimed in claim 1, characterized in that: It includes the following steps: S1, generate a CIP order in the order management unit. The specific steps are as follows: S11, after selecting to add a CIP order in the human-computer interaction module in the order management unit, select the production line, item, order category and order type; S12, after clicking OK, the order management unit selects a standard CIP order from the standard CIP order management module according to the combined screening conditions of production line, item, order category and order type, and obtains CIP parameters according to the standard CIP order; S13, displaying the CIP parameters obtained from the standard CIP order in the human-computer interaction module, clicking the confirmation button after checking, generating the CIP order, and sending the CIP order to the order execution module; S2, the order execution module sends the CIP order to the order storage module and the PLC unit respectively; After receiving the CIP order, the order saving module saves the CIP order. After receiving the CIP order, the PLC unit obtains the CIP parameters from the CIP order and controls the operation of the CIP equipment. S3, CIP equipment operation monitoring; The operation process of CIP equipment is completely executed in accordance with CIP orders; when CIP equipment is running, the real-time operation data of CIP equipment is collected through the sensors of CIP equipment, and the real-time operation data is sent to the PLC unit. The PLC unit then sends the real-time operation data to the order execution module in the order management unit. The order execution module sends the real-time operation data to the order saving module for storage, and compares the real-time operation data with the data in the sensor signal classification file of the selected standard CIP order, and uses the alarm information classification file to monitor the operation of CIP equipment. If the order management unit has an alarm message, the PLC unit will stop the CIP equipment loop where the alarm message appears, and will not enter the next step of the CIP activity; Wait for the operator to confirm the alarm information and then manually intervene to end the current CIP order. If you need to continue the current CIP activity, you need to regenerate the CIP order. Only after a CIP order is completed can the next CIP order be executed, otherwise the CIP order will continue to occupy the PLC unit. S4, according to the CIP process step standard document, complete the cleaning of the circuit in sequence; S5, after the CIP order is executed, the CIP order and real-time operation data will be saved in the order saving module, and the order query module will query, count or analyze the executed historical CIP orders.
7. The method of using the CIP system based on the order model according to claim 6, characterized in that: The following steps are also included: S6, according to the analysis result in S5, modify the parameters in the standard CIP order stored in the standard CIP order management module.
