Description

Technical Field

[0001] The invention relates to a batch information circulation system, a control method and an automatic circulation method for a silk-making workshop, and belongs to the field of industrial control, in particular to the field of cigarette manufacturing. Background Art

[0002] Silk making is an important process in tobacco production. The intelligent application of the silk production process is the main research direction of the industry. However, there are still too many repetitive and complicated operational tasks in the silk making process.

[0003] In the current silk-making process, after the silk-making centralized control system receives the batch information issued by the MES system, it first parses it into command information that can be recognized by the control system, and then closely integrates it with the control of the smoke machine equipment to guide the completion of the entire production. Therefore, the intelligent circulation of batch information in the silk-making centralized control system is a very important key basic work. Batch information is the core information of the entire silk-making production, and the silk-making production is completely based on batch information. However, the application, issuance, release, start, end and collection of batch production information are all manually confirmed. In the process of batch information circulation, operators need to make a lot of information judgments, and after the judgment, they need to perform a lot of operations to complete the control of the production process. The repetitiveness and complexity of the operation can easily lead to errors, which can easily lead to abnormal batch information problems. In addition, the workload of operators is huge and the entire operation process is time-consuming and laborious. Summary of the invention

[0004] In order to solve the above problems, the present invention proposes a silk-making workshop batch information circulation system, control method and automatic circulation method which can solve the batch information abnormality problem caused by human operation errors, reduce the workload of operators, and realize the intelligent application of the production process.

[0005] The batch information circulation system for a silk-making workshop described in the present invention is characterized in that it comprises a silk-making centralized control system, an MES system, and a smoke machine device, wherein the silk-making centralized control system is connected to the MES system by signal, and the silk-making centralized control system is connected to the smoke machine device by signal through an industrial network;

[0006] The silk production centralized control system includes Oracle database server, underlying PLC controller, IGS data acquisition server, and host computer;

[0007] The MES system is connected to the host computer and Oracle database server signals to receive XML files sent from the host computer to the MES system. After receiving the work order application signals from each work section, the acquired production information is collected to generate corresponding production batch information, and the generated production batch information is sent to the Oracle database server for storage in the form of work orders.

[0008] The bottom-level PLC controller is connected with the Oracle database server, IGS data acquisition server, and smoke machine equipment through two-way signals. The bottom-level PLC controller receives and stores the work order information in the database of the Oracle database server, collects the sensor signals on the smoke machine equipment on site, the operating status of each smoke machine equipment, and the actual status information of the materials, and controls the equipment accordingly according to production requirements;

[0009] The IGS server is equipped with a connection channel, which is connected to the bottom-level PLC controller through a two-way signal, and is used to connect to some key data in the bottom-level PLC controller in real time for use by the host computer; the IGS server is also equipped with a data acquisition module, which is used to synchronously push some production information data collected in real time in the bottom-level PLC to the MES system for use by the MES system;

[0010] The host computer has a one-way signal connection with the MES system, and a two-way signal connection with the IGS data acquisition server and the underlying PLC controller. The host computer can be associated with the IGS server through the operation screen. The host computer is used for human-computer interaction to monitor and modify some key data in the underlying PLC controller for production monitoring, program maintenance and application development.

[0011] Preferably, the Oracle database server is connected to the underlying PLC controller by two-way signals, and is used to receive production batch information issued by the MES system, store it in the database in the form of work orders, and write the work order information in the Oracle database server into the equipment data storage area of ​​the underlying PLC controller corresponding to the work section; each work order corresponds to a work section of a production line in a workshop.

[0012] Preferably, each XML file contains different information, including a work order application signal and a work order end production data collection signal.

[0013] Preferably, the underlying PLC controller is connected to the range hood equipment via a two-way signal connection through an industrial network, and is used to control the range hood equipment to apply for work orders, issue work orders, release work orders, start work orders, pause work orders, continue work orders, or end work orders, while automatically collecting and organizing production data.

[0014] The control method of a batch information flow system of a silk-making workshop described in the present invention is characterized by comprising the following steps:

[0015] Step 1: The MES system generates and issues production batch information based on the work order application issued by each work section;

[0016] Step 2: The Oracle database server communicates with the MES system through XML information files, receives the production batch information issued by the MES system, and stores it in the form of work orders. Each work order corresponds to a section of a production line in the workshop;

[0017] Step 3: Write the work order information in the Oracle database server into the device data storage area of ​​the underlying PLC controller corresponding to the work section;

[0018] Step 4. The bottom-level PLC controller collects the sensor signals, operating status of each range hood equipment and actual status information of materials on the on-site range hood equipment, analyzes the collected information and makes independent decisions. According to production requirements, it controls the range hood equipment to apply for work orders, issue work orders, release work orders, start work orders, suspend work orders, continue work orders or end work orders. At the same time, it automatically collects and organizes production data to realize the flow of batch information on the workshop production line.

[0019] An automatic circulation method according to the present invention is characterized by comprising the following steps:

[0020] S1 Each work section performs work order application operations:

[0021] S01 checks whether each work section has currently applied for the next work order. If yes, no application is made. If no, each work section applies for a work order from the MES system separately.

[0022] S02 If the work order is not applied for, repeat the application for the set number of times. If the application is not applied for after the set number of times, no work order will be applied for that day;

[0023] S03 resets the number of unsuccessful applications within the preset reset time the next day;

[0024] After S04 successfully receives the batch information issued by MES, it is stored in the database of the Oracle database server in the form of a work order;

[0025] S2 Each section executes the work order issuance operation:

[0026] S21 checks whether the device data storage area of ​​the bottom PLC controller of the section is empty;

[0027] S22 checks whether there is a work order running in the equipment data application area of ​​the bottom PLC controller of the section;

[0028] S23 If S21 is yes and S22 is no, then the work order information in the database of the Oracle database server is written into the device data storage area of ​​the bottom PLC controller of each work section;

[0029] Each section of S3 performs the work order release operation:

[0030] S31 checks whether the work order information in the device data storage area and the device data application area of ​​the bottom PLC controller of the work section is the same;

[0031] S32 checks whether there is a work order running in the equipment data application area;

[0032] S33 If S31 is no and S32 is no, copy the work order information in the device data storage area to the device data application area and the host device data block;

[0033] S4 Each section executes the work order and starts operation:

[0034] S41 checks whether the work order information in the device data storage area and the device data application area is the same;

[0035] S42 checks whether there is a work order running in the equipment data application area;

[0036] S43 receives the production preparation signal and equipment status from the smoke machine equipment;

[0037] S44 If S41 is yes and S42 is no, after the smoke exhaust fan equipment is ready for production, the work order is executed to start the operation, and the section enters the normal production stage;

[0038] S5 Each section executes the work order to end the operation:

[0039] S51 checks whether the work order information in the device data storage area and the device data application area is the same;

[0040] S52 checks whether there is a work order running in the equipment data application area;

[0041] S53 receives the production end signal and equipment status from the smoke exhaust fan equipment;

[0042] S54: If S41 is yes and S42 is yes, after the smoke exhaust fan equipment is finished producing and enters the standby state, the work order end operation is executed;

[0043] S55 clears the work order information in the data storage area. At this point, the intelligent flow of batch information in the silk-making workshop is completed, and a new round of batch information flow is automatically entered.

[0044] Preferably, during the entire batch circulation process, the work order information is sent to a cache address of the underlying PLC controller, and then released to the actual use address of the underlying PLC controller. While the underlying PLC controller actually uses the data, it passes the information to the collection display address.

[0045] When a work order is issued, the centralized control system writes the work order information in the Oracle database server into the device data storage area of ​​the underlying PLC controller corresponding to the work section; during the production process, the Oracle database server saves the relevant production data and production information in the underlying PLC controller as needed.

[0046] The beneficial effects of the present invention are: by realizing the intelligent flow of batch information, abnormal batch information problems caused by human operational errors are avoided, the complexity of the work of silk-making centralized control operators is reduced, the batch change time is shortened to improve production efficiency, and the automation, unmanned and intelligent level of the silk-making workshop is greatly improved.

[0058] The silk-making workshop batch information circulation system of the present invention comprises a silk-making centralized control system 1, an MES system 2, and a smoke machine device 3. The silk-making centralized control system 1 is connected to the MES system 2 by signals, and the silk-making centralized control system 1 is connected to the smoke machine device 3 by signals via an industrial network.

[0059] The silk production centralized control system 1 includes an Oracle database server 11, a bottom-level PLC controller 12, an IGS data acquisition server 13, and a host computer 14;

[0060] The MES system 2 is connected to the host computer 14 and the Oracle database server 11 by signals, and is used to receive the XML file sent from the host computer to the MES system. After receiving the work order application signal issued by each work section, the data collected by the production information is collected to generate the corresponding production batch information, and the generated production batch information is sent to the Oracle database server for storage in the form of work orders;

[0061] The bottom-level PLC controller 12 is connected with the Oracle database server 11, the IGS data acquisition server 13, and the smoke machine equipment 3 by two-way signals. The bottom-level PLC controller 12 receives and stores the work order information in the database of the Oracle database server 11, collects the sensor signals on the smoke machine equipment 3 on site, the operating status of each smoke machine equipment and the actual status information of the materials, and controls the equipment accordingly according to the production requirements;

[0062] The IGS data acquisition server 13 is equipped with a connection channel, and is connected to the bottom PLC controller through a two-way signal connection, which is used to connect to some key data in the bottom PLC controller in real time for use by the host computer; the IGS data acquisition server 13 is also equipped with a data acquisition module, which is used to synchronously push some production information data in the bottom PLC collected in real time to the MES system 2 for use by the MES system;

[0063] The host computer 14 is connected to the MES system 2 by one-way signals, and is connected to the IGS data acquisition server 13 and the underlying PLC controller 12 by two-way signals. The host computer 14 is used for human-computer interaction to monitor and modify some key data in the underlying PLC controller 12 for production monitoring, program maintenance and application development.

[0064] In some embodiments of the present invention, the Oracle database server 11 is connected to the underlying PLC controller 12 by bidirectional signals, and is used to receive production batch information issued by the MES system, store it in the database in the form of work orders, and write the work order information in the Oracle database server into the equipment data storage area of ​​the underlying PLC controller corresponding to the work section; each work order corresponds to a work section of a production line in a workshop.

[0065] In some embodiments of the present invention, each XML file contains different information, including a work order application signal and a work order end production data collection signal.

[0066] In some embodiments of the present invention, the underlying PLC controller 12 is connected to the range hood equipment 3 through a bidirectional signal through an industrial network, and is used to control the range hood equipment to apply for work orders, issue work orders, release work orders, start work orders, pause work orders, continue work orders, or end work orders, while automatically collecting and organizing production data.

[0067] A control method for a batch information flow system in a silk-making workshop according to the present invention comprises the following steps:

[0068] Step 1, MES system 2 generates and issues production batch information based on the work order application issued by each work section;

[0069] Step 2, the Oracle database server 11 communicates with the MES system 2 through the XML information file, receives the production batch information issued by the MES system 2, and stores it in the form of work orders, each work order corresponding to a work section of a production line in the workshop;

[0070] Step 3: Write the work order information in the Oracle database server 11 into the device data storage area of ​​the underlying PLC controller 12 corresponding to the work section;

[0071] Step 4, the bottom-level PLC controller 12 collects the sensor signals of the range hood equipment 3 on site, the operating status of each range hood equipment 3 and the actual status information of the materials, and analyzes and makes independent decisions on the collected information. According to production requirements, the range hood equipment 3 is controlled to apply for work orders, issue work orders, release work orders, start work orders, suspend work orders, continue work orders or end work orders. At the same time, the production data is automatically collected and sorted to realize the flow of batch information on the workshop production line.

[0072] Specifically, the MES system 2 is used to generate and issue production batch information; the silk making centralized control system 1 is used to receive and parse the command information that can be recognized by the control system and store it in the database, and then transfer the production batch information to the smoke machine equipment 3 level during the production process, and automatically perceive the actual status of the smoke machine equipment 3 and materials on site in real time, establish a mathematical model, analyze the perceived information and make independent decisions, thereby accurately implementing actions such as applying for work orders, issuing work orders, releasing work orders, starting work orders, suspending work orders, continuing work orders or ending work orders, and automatically collecting and organizing production data. The entire process does not require human intervention, thereby realizing the intelligent flow of batch information on the workshop production line.

[0073] An automatic circulation method according to the present invention comprises the following steps:

[0074] S1 Each work section performs work order application operations:

[0075] S01 checks whether each work section has currently applied for the next work order. If yes, no application is made. If no, each work section applies for a work order from MES system 1 respectively.

[0076] S02 If the work order is not applied for, repeat the application for 3 times. If it is not applied for 3 times, no work order will be applied for that day;

[0077] S03 The number of unclaimed times will be reset between 6:00 and 6:10 a.m. the next day;

[0078] After S04 successfully receives the batch information issued by MES, it is stored in the database of the Oracle database server in the form of a work order;

[0079] S2 Each section executes the work order issuance operation:

[0080] S21 checks whether the device data storage area of ​​the bottom PLC controller of the section is empty;

[0081] S22 checks whether there is a work order running in the equipment data application area of ​​the bottom PLC controller of the section;

[0082] S23 If S21 is yes and S22 is no, then the work order information in the database of the Oracle database server is written into the device data storage area of ​​the bottom PLC controller of each work section;

[0083] Each section of S3 performs the work order release operation:

[0084] S31 checks whether the work order information in the device data storage area and the device data application area of ​​the bottom PLC controller of the work section is the same;

[0085] S32 checks whether there is a work order running in the equipment data application area;

[0086] S33 If S31 is no and S32 is no, copy the work order information in the device data storage area to the device data application area and the host device data block;

[0087] S4 Each section executes the work order and starts operation:

[0088] S41 checks whether the work order information in the device data storage area and the device data application area is the same;

[0089] S42 checks whether there is a work order running in the equipment data application area;

[0090] S43 receives the production preparation signal and equipment status from the smoke machine equipment;

[0091] S44 If S41 is yes and S42 is no, after the smoke exhaust fan equipment is ready for production, the work order is executed to start the operation, and the section enters the normal production stage;

[0092] S5 Each section executes the work order to end the operation:

[0093] S51 checks whether the work order information in the device data storage area and the device data application area is the same;

[0094] S52 checks whether there is a work order running in the equipment data application area;

[0095] S53 receives the production end signal and equipment status from the smoke exhaust fan equipment;

[0096] S54: If S41 is yes and S42 is yes, after the smoke exhaust fan equipment is finished producing and enters the standby state, the work order end operation is executed;

[0097] S55 clears the work order information in the data storage area. At this point, the intelligent flow of batch information in the silk-making workshop is completed, and a new round of batch information flow is automatically entered.

[0098] In the entire batch circulation process of the present invention, we first send the work order information to a cache address of the PLC (for example: data storage area DB600), and then release it to the actual use address of the PLC (for example: DB316 used to transfer information to the host device data block). While the PLC actually uses the data, it also transfers the information to the collection display address (for example: data application area DB601).

[0099] The present invention subdivides the batch flow process in this way, which provides a buffer zone for our use and timely error correction. And for the database management system, we separate reading and writing, for example, DB600 is the address we write into the PLC, DB601 is the read address, and DB316 is the address actually used by the PLC itself, so that the functional division is clear and does not affect each other's data.

[0100] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
