[0025] The order processing method and device for chemical production according to the embodiments of this specification will be described in detail below with reference to the accompanying drawings.

[0026] Figure 1 An exemplary architecture 100 of an order processing method and apparatus for chemical production according to an embodiment of the present specification is shown.

[0027] exist Figure 1 In the example, the network 110 is used to connect the production management system 120, the equipment control system 130, the order issuing system 140, and the production equipment 150.

[0028] The network 110 may be any type of network capable of interconnecting network entities. The network 110 may be a single network or a combination of various networks. In terms of coverage, the network 110 may be a local area network (LAN), a wide area network (WAN), etc. In terms of carrier media, the network 110 may be a wired network, a wireless network, etc. In terms of data exchange technology, the network 110 may be a circuit switching network, a packet switching network, etc.

In some examples, the equipment control system 130 may be a distributed control system (DCS). In some examples, the equipment control system 130 may be an industrial control computer. In some examples, the equipment control system 130 may also be a programmable logic controller (PLC). In some examples, the equipment control system 130 may also be a control system composed of an industrial control computer as a host computer and a PLC as a slave computer. In some examples, the industrial control computer may also be installed with a Windows Control Center (WinCC). In some examples, the production equipment 150 may include, for example, an extruder, a granulator, etc. The equipment control system 130 can realize information collection and start-stop control of the corresponding equipment by sending corresponding instructions to various sensors, motors, etc. installed on the production equipment 150.

[0030] It should be understood that Figure 1 All network entities shown in the figure are exemplary. Any other network entities may be involved in the architecture 100 according to specific application requirements.

[0031] Figure 2 A flowchart of an example 200 of an order processing method for chemical production according to an embodiment of the present specification is shown.

[0032] like Figure 2 As shown, at 210, in response to receiving the order confirmation information sent by the device control system, the status of the order indicated by the order confirmation information is set to a confirmed status.

[0033] In this embodiment, the production management system may receive order confirmation information from the equipment control system. After receiving the order confirmation information, it means that the equipment control system confirms that the order has been received and the communication status between the two is normal, so that the status of the order indicated by the order confirmation information can be set to a confirmed state. In some examples, the order confirmation information may include identification information for distinguishing different orders. In some examples, when orders are processed one by one, the order confirmation information may also be an acknowledgement character (ACK).

[0034] In some examples, the production management system may first send order information to the device control system. In some examples, the order information may include an order identifier. In some examples, the order identifier may be in the form of an order number, a unique identification code, etc. In some examples, the production management system may obtain the order information from the order issuing system. In some examples, the order information may also include information indicating the type of order. In some examples, the order information may also include recipe information indicating the raw materials required for production.

[0035] In some examples, the production management system may also start a timer after sending order information to the equipment control system. If order confirmation information is received from the equipment control system before the timer reaches a predetermined time, the status of the order indicated by the order confirmation information may be set to a confirmed status. If the order confirmation information sent by the equipment control system is still not received after the timer reaches the predetermined time, it means that the equipment control system may not have received the order or the communication status between the two is abnormal, and the above order information may be resent to the equipment control system.

[0036] At 220 , it is determined whether to switch the state of the order from the confirmed state to the ready state according to the order interlocking mode that matches the type of the order in the confirmed state.

[0037] In this embodiment, orders can be divided into different types. In some examples, the type of an order can be reflected by an order identifier. In some examples, the type of an order can be reflected by the type information it has.

[0038] In this embodiment, the type of order in the confirmed state can be acquired or stored in advance. The order interlocking mode of the order in the confirmed state can be determined according to the correspondence between the type of order and the order interlocking mode set in advance, and then it can be determined whether the state of the order can be switched from the confirmed state to the ready state. In some examples, the production management system can manage the state of the order, and the "order interlocking mode" can be used to indicate the way to restrict the switching of the order state.

[0039] In some examples, the type of order may include a common type, for example, it may be represented by "0". In some examples, the common type may be used to represent a regular order. This type of order usually requires confirmation before the product starts to be produced whether the relevant feeding equipment has cleared the raw materials required for the previous production process, that is, whether the discharge is completed.

[0040] In some examples, the type of order may include a continuous production type, which may be represented by "1", for example. In some examples, the continuous production type may be used to represent orders that can be produced continuously without stopping the equipment. Since this type of order can be produced continuously, after the production of the previous order is completed, it is not necessary to clean up the raw materials required for the previous production process before the next order starts production. In some examples, the continuous production type order may be a series of orders classified by the order scheduling system according to the production materials corresponding to the order. In some examples, the order scheduling system may issue the type of order to the production management system through the order issuing system.

[0041] Figure 3 A flowchart showing an example of a control process 300 for switching the status of an order according to an embodiment of the present specification.

[0042] like Figure 3 As shown, at 310, recipe information of a common type of order in a confirmed state is obtained.

[0043] In this embodiment, the recipe information is used to indicate the raw materials required for production. In some examples, the corresponding recipe information can be obtained from the recipe management system according to the order identification of the common type of order in the confirmed state. In some examples, when the order information is obtained from the order issuing system, the order representation, the type of order and the corresponding recipe information of each order obtained can be stored, so that the recipe information of the common type of order in the confirmed state can be obtained from the stored recipe information.

[0044] In some examples, the formula information is also used to indicate rework materials and / or premixes. In these examples, since the components of the various raw materials contained in the rework materials are basically the same as those of the finished products, they can be regarded as raw materials prepared in proportion. By re-investing a certain proportion of the rework materials into the production equipment (such as an extruder) for re-production during the production process, and turning them into qualified finished products after passing the inspection, waste can be effectively reduced. In some examples, premixes can be used to indicate materials obtained by pre-mixing two or more raw materials required for production in the proportions required for production.

[0045] At 320, corresponding feeding equipment information is obtained according to the recipe information.

[0046] In some examples, the feeding equipment information corresponding to the recipe information can be obtained according to a preset rule. In some examples, the corresponding feeding equipment information can be determined according to the raw material storage location and raw material form (e.g., granules, powder, etc.) indicated by the recipe information. In some examples, the corresponding feeding equipment information can be obtained according to a preset material-equipment correspondence table. For example, the material-equipment correspondence table can be used to indicate that material X corresponds to equipment 101 and material Y corresponds to equipment 105.

[0047] In some examples, the corresponding feeding equipment information can be obtained according to the preset material-equipment correspondence table for various raw materials, rework materials and / or premixes indicated by the formula information. In some examples, the material-equipment correspondence table can be used to indicate that the rework material R corresponds to the equipment 107 and the premix S corresponds to the equipment 109.

[0048] Through the above method, it is creatively proposed to introduce rework materials and / or premixes in the order production process by adding equipment corresponding to rework materials and / or premixes, so that the order interlocking method using the above scheme can not only improve the utilization efficiency of materials through rework materials, but also reduce the number of equipment required to be used and maintained through premixes, thereby reducing unnecessary waste and achieving green and low-carbon.

[0049] At 330, it is determined whether each feeding device indicated by the feeding device information has completed discharging.

[0050] In some examples, the amount of material in the corresponding feeding device can be determined by a material quantity detection device provided on each feeding device. If the amount of material in the feeding device is 0, it can be determined that the feeding device has completed discharging. If the amount of material in the feeding device is greater than 0, it can be determined that the feeding device has not completed discharging. In some examples, due to a certain error, a positive number close to 0 (for example, 0.5) can also be set as a threshold. If the amount of material in the feeding device is less than the above threshold, it can be determined that the feeding device has completed discharging. If the amount of material in the feeding device is not less than the above threshold, it can be determined that the feeding device has not completed discharging.

[0051] In some examples, it is also possible to determine whether the amount of material in the corresponding feeding device has changed by using a material amount detection device provided on each feeding device. If it is detected that the amount of material is gradually decreasing, it can be determined that the feeding device is discharging material. In these examples, re-detection can be performed after the amount of material becomes stable.

[0052] In some examples, after 370 has been executed at least once, it is possible to re-determine whether the discharging has been completed for each feeding device corresponding to the order, thereby avoiding as much as possible the misjudgment of the feeding devices that have not completed discharging due to mistakes or accidental deviations; it is also possible to re-determine whether the discharging has been completed only for the feeding devices corresponding to the order that have been confirmed to have not completed discharging, thereby improving efficiency.

[0053] If the judgment at 330 is yes, at 340, the status of the order is switched from the confirmed status to the ready status.

[0054] In some examples, after re-determining whether the feeding device has completed discharging (ie, executing 370), the status of the order can also be switched from a state of needing to discharge to a state of being ready.

[0055] In some examples, if the determination at 330 is no, the following 350 - 370 are executed.

[0056] At 350 , the necessity information of the material discharging of the feeding equipment that has not yet been fully discharged is determined according to the recipe information of the first associated order.

[0057] In this embodiment, the discharge necessity information is used to indicate whether the feeding equipment must undergo discharge before the production process of the current order is started. In some examples, the first associated order may be the order corresponding to the previous production process completed by the feeding equipment. If the material carried by the feeding equipment in the previous production process indicated by the formula information of the first associated order is consistent with the material carried by the feeding equipment in the production process of the current order, the discharge necessity information of the feeding equipment may indicate that discharge is not required. If the material carried by the feeding equipment in the previous production process indicated by the formula information of the first associated order is inconsistent with the material carried by the feeding equipment in the production process of the current order, the discharge necessity information of the feeding equipment may indicate that discharge is required.

[0058] At 360 , it is determined whether the determined nesting necessity information indicates that nesting is required.

[0059] If the judgment at 360 is no, execute 340.

[0060] If the answer at step 360 is yes, at step 370 , a material placement prompt message is sent; and the process returns to step 330 .

[0061] In this embodiment, in response to the determined discharge necessity information indicating that discharge is required, discharge prompt information can be sent to the designated device. In some examples, the designated device can be, for example, a terminal device used by an operator, so that the operator can be instructed to discharge the device. In some examples, the designated device can be, for example, a device capable of controlling the automatic discharge of a feeding device, so that the feeding device can be discharged by sending instructions to a discharge valve.

[0062] In some examples, after receiving the discharge prompt information through the terminal device, the operator can also use the scanning device to scan the equipment label of the feeding equipment to be discharged, thereby generating the identification information of the feeding equipment to be discharged. The production management system can obtain the feeding equipment identification information from the above scanning device. If it is confirmed that the feeding equipment identification information is consistent with the feeding equipment indicated by the discharge prompt information, it can send an instruction to the equipment control system to release the valve locking mode of the feeding equipment; if it is confirmed that the feeding equipment identification information is inconsistent with the feeding equipment indicated by the discharge prompt information, the valve locking mode of the feeding equipment is maintained, thereby avoiding the wrong valve opening affecting the normal operation of the equipment.

[0063] In some examples, after the material discharging reminder information is sent, the process may return to execute 330. In some examples, after the material discharging reminder information is sent, a predetermined waiting time (eg, 10 minutes) may be waited before returning to execute 330.

[0064] In some examples, in response to the determined nesting necessity information indicating that nesting is required, the status of the order can be switched from a confirmed status to a nesting required status.

[0065] Through the above method, the characteristics of ordinary orders in different situations can be fully considered, and a more targeted interlocking logic can be implemented according to the different discharge requirements between the corresponding feeding equipment.

[0066] Figure 4 A flowchart showing another example of a control process 400 for switching the state of an order according to an embodiment of the present specification.

[0067] like Figure 4 As shown, at 410, based on the type of the second associated order, it is determined whether the order currently in a confirmed state and belonging to the continuous production type is the first continuous production order.

[0068] In some examples, the second associated order may be an order corresponding to the previous production process of the production equipment controlled by the equipment control system. In some examples, the second associated order may be the previous order of an order sent to the equipment control system, which is currently in a confirmed state and belongs to a continuous production type. If the type of the second associated order also belongs to the continuous production type, it can be determined that the order currently in a confirmed state and belongs to the continuous production type is not the first continuous production order, which means that no scheduling is required. If the type of the second associated order does not belong to the continuous production type, it can be determined that the order currently in a confirmed state and belongs to the continuous production type is the first continuous production order, which means that it is necessary to refer to the ordinary type of order to determine whether scheduling is required.

[0069] If the determination at 410 is negative, at 420 , the state of the order in the confirmed state is switched from the confirmed state to the ready state.

[0070] If the judgment at 410 is yes, the following 430-480 are executed.

[0071] At 430 , recipe information of a continuous production type order in a confirmed state is acquired.

[0072] At 440, corresponding feeding equipment information is obtained according to the recipe information.

[0073] At 450, it is determined whether each feeding device indicated by the feeding device information has completed discharging.

[0074] If the answer at step 450 is yes, execution proceeds to step 420 .

[0075] In some examples, if the determination at 450 is no, the following 460 - 480 are executed.

[0076] At 460 , the necessity information of the material discharging of the feeding equipment that has not yet been fully discharged is determined according to the recipe information of the first associated order.

[0077] At 470 , it is determined whether the determined nesting necessity information indicates that nesting is required.

[0078] If the determination in step 470 is no, execution proceeds to step 420 .

[0079] If the result of 470 is yes, at 480 , a material placement prompt message is sent; and the process returns to 450 .

[0080] In some examples, 430-480 may refer to Figure 3 310-370 described are not repeated here.

[0081] Through the above method, targeted control of state switching of continuous production type orders can be achieved.

[0082] Back to Figure 2 At 230, the status of the order is synchronized to the equipment control system so that the equipment control system starts the production process for the order in the ready state.

[0083] In this embodiment, the status of the order can be synchronized to the device control system. Afterwards, the device control system can start the production process for the order in the ready state to complete the order.

[0084] Figure 5 A signaling diagram showing yet another example of an order processing method 500 for chemical production according to an embodiment of the present specification.

[0085] like Figure 5 As shown, at 510, the equipment control system sends order confirmation information to the production management system.

[0086] At 520 , the production management system sets the status of the order indicated by the received order confirmation information to a confirmed status.

[0087] At 530 , the production management system determines whether to switch the state of the order from the confirmed state to the ready state according to the order interlocking mode that matches the type of the order in the confirmed state.

[0088] At 540 , the production management system synchronizes the status of the order to the equipment control system, so that the equipment control system starts the production process for the order in the ready state.

[0089] It should be noted that the above 510-540 can refer to the aforementioned Figure 2 The corresponding descriptions of Examples 210-240 will not be repeated here.

[0090] At 550, the equipment control system sends order completion information to the production management system.

[0091] In this embodiment, the device control system may send order completion information to the production management system after completing the order. In some examples, the order completion information may include identification information for distinguishing different orders. In some examples, when orders are processed one by one, the order completion information may also be various characters for indicating order completion without including identification information for distinguishing different orders.

[0092] At 560 , the production management system sets the status of the order indicated by the received order completion information to a completed status.

[0093] At 570 , the production management system synchronizes the status of the order to the equipment control system.

[0094] At 580, the production management system sends the new order information to the equipment control system.

[0095] In this embodiment, the order information may include the identification, type and recipe information of the order. Afterwards, the order processing method as described above may be continuously executed to complete the continuous processing of multiple orders.

[0096] In the above manner, the status of orders can be synchronized through the interaction between the equipment control system and the production management system, and the tracking and management of the entire life cycle of the order can be completed, thereby realizing the continuous processing of multiple orders.

[0097] use Figure 1-Figure 5 The order processing method for chemical production disclosed in the document ensures that the order is correctly issued to the equipment control system through order confirmation information, further controls the switching of the order from the confirmed state to the ready state according to the order interlocking method matching the order type, and synchronizes the order status to the equipment control system, thereby ensuring that each step of the order status switching is accurate, realizing the full-process automated management of chemical production orders, which is of positive significance for ensuring correct and continuous production.

[0117] In some examples, the order processing device 600 may further include an information sending unit 630. The information sending unit 630 is configured to synchronize the order status to the device control system and send new order information to the device control system, wherein the order information includes the order identification, type and recipe information.

[0118] It should be noted that the operations of the order status switching unit 610, the order status synchronization unit 620 and the information issuing unit 630, the recipe acquisition module 710, the feeding equipment status judgment module 720 and the order status switching module 730, the order type determination module 810 and the order status switching module 820 can refer to the above Figure 2-Figure 5 Related description.

[0120] like Fig. 9 As shown, the order processing system 900 may include an order processing device 910 and a production control device 920. In some examples, the production control device 920 may include an instruction sending unit 921 and a state locking unit 922. In some examples, the production control device 920 may also include a timing unit 923.

[0121] The instruction sending unit 921 is configured to send a start instruction to the corresponding production equipment that meets the equipment start requirement according to the order in the ready state, so as to start the production process of the order in the ready state.

[0122] In some examples, satisfying the equipment startup requirement may be correctly connected to the feeding equipment in a confirmed state. The confirmed state may be a state where the material has been discharged or a state where no material discharge is required. In some examples, the confirmed state may also be connected to the corresponding silo or the large bag of raw materials for feeding is ready. In some examples, the corresponding production equipment may include, for example, an extruder, a granulator, etc. In these examples, when the production equipment receives the startup instruction, it may start producing the products corresponding to the order in the ready state.

[0123] The state locking unit 922 is configured to prohibit sending order completion information to the production management system before starting the production process; and to release the lock on sending order completion information after starting the production process.

[0124] In some examples, before the production process is started, the operation of sending order completion information to the production management system cannot be triggered; after the production process is started, the above operation can be unlocked. In some examples, the button indicating the completion of the production process can be locked before the production process is started, and after the production process is started, the button indicating the completion of the production process can be unlocked. When the button is unlocked, the operator can send the order completion information to the production management system by clicking the button.

[0125] In some examples, the timing unit 923 is configured to start timing according to a preset mechanism if the order that starts the production process belongs to a continuous production type, and stop timing when new order information of the same type is received or a predetermined time is reached. In some examples, the preset mechanism can be used to indicate that the timing starts when the production process is started. In some examples, the preset mechanism can be used to indicate that the timing starts when the order completion information is sent to the production management system. In some examples, the predetermined time can be, for example, 1200 seconds.

[0126] In some examples, the instruction sending unit 921 is further configured to determine whether to send a stop operation instruction to the corresponding production equipment after the production process is completed based on the timing of the timing unit 923 if the order that starts the production process is of a continuous production type.

[0127] In some examples, if the timing unit 923 reaches a predetermined time, it means that no new order information of the continuous production type is received, and a stop operation instruction can be sent to the corresponding production equipment after the production process is completed. In some examples, whether the production process is completed can be determined by whether order completion information is sent to the production management system.

[0128] It should be noted that the order processing device 910 can refer to the above Figure 6-Figure 8 Related description in .

[0129] In the above manner, the production control device 920 can control the corresponding production equipment to perform production according to the status of the order determined by the order processing device 910, and provide a basis for ensuring efficient, continuous and stable production through information interaction between the production control device 920 and the order processing device 910.
