Description

Technical Field

[0001] The present disclosure relates to the technical field of pickled vegetables such as mustard tuber pickling, and more particularly to a control method for controlling a plurality of valves in a pickled vegetable brine transport system. Background Art

[0002] Pickled vegetables such as zhacai are very popular and delicious side dishes. They have a crisp texture and delicious flavor.

[0003] In the traditional pickling process of mustard tuber, the brine transfer system is a key link, which involves complex scheduling between multiple brine pools and functional pools. With the increasing demand for production automation, the traditional manual operation mode is gradually being replaced by the automation system. However, the introduction of the automation system requires a careful interlocking protection mechanism to ensure the correct scheduling and operation efficiency of the brine transfer system.

[0004] The main purpose of the interlock protection mechanism is to ensure that at any given moment, the brine transfer system scheduling operation is safe in the automation system to prevent cross-contamination of materials and equipment damage. This usually involves precise control of the various valves and paths in the system. In actual production, due to the large number of salting tanks and functional tanks and the complex paths, it is necessary to design an interlock protection system that can handle a large number of combinations.

[0005] like Figure 1 As shown, the salting pool includes a plurality of first salting pools and a plurality of second and third salting pools, and the functional pool includes a plurality of sewage pools, a plurality of filtration pools, a plurality of high-concentration salt water pools with a salt water concentration greater than a predetermined salt water concentration, a plurality of low-concentration salt water pools with a salt water concentration less than the predetermined salt water concentration, a plurality of pure water pools, a sewage main pipeline and a plurality of cleaning pipelines. Figure 1 As shown, due to the large number of pickling pools and the complex scheduling paths after processing in the functional pools, strict interlocking protection is required to avoid the crossover of materials in actual production. According to the results of path analysis, there are more than 8,000 combinations of interlocking protection points, so how to simplify complex problems is a challenge.

[0006] In addition, there are two paths for a pickling pool to pass through a functional pool, namely, Figure 1 The brine supply pipe on the left side enters a path and Figure 1 The brine supply pipeline on the right side of the brine enters a path. Therefore, if 100 salting tanks pass through 12 functional pools, there will be up to 2,400 paths. The difference in each path means that the protection of the valve also needs to be changed accordingly. Therefore, to design an effective interlock protection mechanism, it is necessary to consider more than 8,000 combinations of salting tanks passing through functional pools, which is a huge challenge in the actual production process.

[0007] In the actual production process, there are situations where 12 functional pools are used at the same time, which will result in a scenario where the functional pools are crossed.

[0008] Therefore, when ensuring efficient production of the brine transfer system, how to automatically interlock and protect the multiple valves of the brine transfer system is a complex problem that needs to be solved urgently. Summary of the invention

[0009] 1. Technical issues

[0010] In view of the above-mentioned shortcomings of the prior art, the present invention provides a control method, a control device and a computer-readable storage medium for controlling multiple valves of a pickled vegetable brine transfer system, which solves the problem of how to automatically interlock and protect multiple valves of the brine transfer system in a simple manner.

[0011] (II) Technical solution

[0012] To achieve the above objectives, the present disclosure is implemented through the following technical solutions:

[0013] According to one aspect of an embodiment of the present disclosure, a control method for controlling multiple valves of a pickled vegetable brine transfer system is provided, wherein the pickled vegetable brine transfer system comprises n pickling pools, multiple brine supply pipes for supplying brine to each pickling pool, multiple brine discharge pipes for discharging brine from each pickling pool, and multiple transfer units for intermediately processing the brine from the n pickling pools, wherein each pickling pool comprises an inlet valve for controlling the entry of brine and an outlet valve for controlling the discharge of brine, the brine supply pipe is connected to the inlet valve of the pickling pool, and the brine discharge pipe is connected to the outlet valve of the pickling pool, and the control method comprises: assigning a pickling pool index for identifying the pickling pool to each pickling pool; dividing the n pickling pools into m groups evenly according to the pickling pool index, wherein each group forms a node and comprises s pickling pools, at least Two nodes share a brine supply pipeline, and at least two nodes share several brine discharge pipelines of multiple brine discharge pipelines, wherein n, m and s are non-zero integers; an inlet valve index and an outlet valve index are assigned to the inlet valve and the outlet valve of the pickling pool, and the inlet valve index and the outlet valve index of each pickling pool are associated with the pickling pool index of the pickling pool; a recipe pattern indicating the recipe of the pickled vegetable brine transportation system is determined, and a transportation path of the brine is determined based on the recipe pattern, the transportation path includes a source pickling pool, a transfer unit to be passed through, and a destination, wherein the source pickling pool is one of the n pickling pools; based on the determined pickling pool index of the source pickling pool, polling of multiple nodes is performed to control the inlet valve and the outlet valve of the source pickling pool to be opened and the inlet valve and the outlet valve of the pickling pool other than the source pickling pool to be closed.

[0014] In this way, by sequencing the irregular numerous salting pools and valve rules and forming multiple salting pools into a node, the opening and closing of the inlet valve and outlet valve of the salting pool can be controlled by a simple node polling method, so that the multiple valves of the salt water transfer system can be automatically interlocked and protected by simple programs and codes. Moreover, since the valve-related interlocks, commands, etc. can be implemented in a polling manner, the advantage is that the amount of code is minimized. In addition, the interface of all data can be realized as a database, so that the actual opening and closing valve commands become simple, and an interface is reserved for later expansion such as adding salting pools. For example, the subsequent additions are filled in according to the designed rules, which greatly shortens the time for testing such as modifying the old path or adding the new path caused by the later addition of salting pools.

[0015] According to an exemplary embodiment of the present disclosure, performing polling of multiple nodes to control the inlet valve and outlet valve of the source pickling pool to open and the inlet valve and outlet valve of the pickling pools other than the source pickling pool to close includes: identifying the node where the source pickling pool is located as an activated node, wherein the nodes not including the source pickling pool are identified as inactivated nodes; identifying a first inactivated node that shares a brine supply pipeline with the source pickling pool and a second inactivated node that shares several brine discharge pipelines with the source pickling pool among the inactivated nodes; and controlling the inlet valve and outlet valve of other pickling pools other than the source pickling pool in the activated nodes to close and controlling the inlet valve of the pickling pool in the first inactivated node to close and the outlet valve of the pickling pool in the second inactivated node to close.

[0016] In this way, the opening and closing of the inlet valves and outlet valves of a large number of combined salting tanks can be quickly and accurately controlled.

[0017] According to an exemplary embodiment of the present disclosure, several brine discharge pipes in which at least two nodes share multiple brine discharge pipes include at least four nodes sharing several brine discharge pipes, whereby the control method includes: forming a first parent node with at least two nodes sharing a brine supply pipe; forming a second parent node with at least four nodes sharing several brine discharge pipes; determining the first parent node and the second parent node where the source marinating tank is located; polling the multiple first parent nodes to control the closure of the inlet valves of the marinating tanks in all other first parent nodes except the first parent node where the source marinating tank is located; and polling the multiple second parent nodes to control the closure of the outlet valves of the marinating tanks in all other second parent nodes except the second parent node where the source marinating tank is located.

[0018] In this way, it is possible to implement interlocking protection by splicing large nodes and small nodes, thereby making interlocking protection simpler and requiring less code.

[0019] According to an exemplary embodiment of the present disclosure, the node where the source salting tank is located is used as an activated node, and the node excluding the source salting tank is used as an inactive node, and the inactive nodes include a first inactive node that shares a brine supply pipeline with the source salting tank and a second inactive node that shares several brine discharge pipelines with the source salting tank. The control method includes polling the nodes in the first parent node where the source salting tank is located to control the closure of the inlet valve of the salting tank in the first inactive node; and polling the nodes in the second parent node where the source salting tank is located to control the closure of the outlet valve of the salting tank in the second inactive node.

[0020] In this way, it is possible to realize individual interlocking protection of small nodes and combined interlocking protection of large and small nodes, thereby making interlocking protection simpler and further reducing the amount of code.

[0021] According to an exemplary embodiment of the present disclosure, a pickled vegetable brine transfer system includes a first area, a second area and a third area located between the first area and the second area, n pickling pools are distributed in the first area and the second area, a plurality of transfer units are distributed in the third area, the first area includes a plurality of first brine supply pipes and a plurality of first brine discharge pipes, the second area includes a plurality of second brine supply pipes and a plurality of second brine discharge pipes, and the control method further includes: forming a common node with the plurality of transfer units, the common node includes a plurality of branch transfer pipes connected to the plurality of first brine supply pipes and the plurality of second brine supply pipes and the plurality of first brine discharge pipes and the plurality of second brine discharge pipes, each of the plurality of branch transfer pipes includes a control valve for controlling the flow of brine into the branch transfer pipe; and controlling the opening of the control valves of corresponding branch transfer pipes in the plurality of branch transfer pipes according to a transfer path determined based on a recipe pattern.

[0022] In this way, by using multiple transfer units as common nodes, the control of brine scheduling of the entire pickled vegetable brine transfer system can be simplified, and the automated control of the pickled vegetable brine transfer system can be more easily achieved.

[0023] According to an exemplary embodiment of the present disclosure, each of the multiple transfer units is connected to a plurality of first brine supply pipes and a plurality of second brine supply pipes and a plurality of first brine discharge pipes and a plurality of second brine discharge pipes through a plurality of branch transfer pipes, and the transfer unit includes an inlet valve for controlling the entry of brine into the transfer unit and an outlet valve for controlling the discharge of brine, and the control method further includes: determining the brine discharge pipe through which the brine discharged from the source salting tank passes based on a recipe pattern; controlling the opening of the control valves of the corresponding branch transfer pipes of the multiple branch transfer pipes according to the determined brine discharge pipe; and controlling the opening of the inlet valve and the outlet valve of the transfer unit to be passed.

[0024] According to an exemplary embodiment of the present disclosure, the transfer path includes a first transfer path from a first brine discharge pipe in a first area through a transfer unit and a second transfer path from a brine discharge pipe in a second area through a transfer unit, and the control method further includes: determining whether the first transfer path or the second transfer path is selected as the transfer path; and determining a series of branch transfer pipes that the transfer path passes through in sequence from the determined brine discharge pipe based on the determination result; and opening the control valves on a series of branch transfer pipes arranged from the determined brine discharge pipe in sequence based on the opening state of the control valve on the determined brine discharge pipe.

[0025] In this way, many branch paths in the transit node can be controlled by upstream transmission and downstream inheritance, so that the chain protection mechanism can be completed in a very large number of paths in a simple way.

[0026] According to an exemplary embodiment of the present disclosure, a plurality of control signals associated with each relay unit are generated based on relay processing performed by a plurality of relay units; a plurality of control signals are combined to generate a valve control command; inlet valve addresses are assigned to inlet valves of n pickling pools in a first order, and the inlet valve addresses and inlet valve indexes are mapped to each other; outlet valve addresses are assigned to outlet valves of n pickling pools in a second order, and the outlet valve addresses and outlet valve indexes are mapped to each other; and the outlet valve address or the inlet valve address of the pickling pool is addressed by converting the valve control command into a corresponding outlet valve address or a corresponding inlet valve address; the inlet valve of the pickling pool having the addressed inlet valve address is controlled to open, and the outlet valve of the pickling pool having the addressed outlet valve address is controlled to open.

[0027] According to an exemplary embodiment of the present disclosure, combining the plurality of control signals to generate the valve control command includes: combining the plurality of control signals in an OR operation.

[0028] In this way, the valves of multiple saltwater pools can be controlled by polling plus indirect addressing, making the automation control more accurate. When adding new equipment, you only need to assign it an address and update the polling list, which is easy to expand the system. Moreover, through addressing, the system can accurately identify and control specific equipment instead of blindly polling all equipment.

[0030] In this way, the interface of all data is a memory, which makes the actual command of switching valves simple. It also provides a reserved interface for later expansion such as adding a pickling pool, which can be filled in according to the designed rules. This greatly shortens the testing time of modifying old paths or adding new paths caused by adding a pickling pool in the future.

[0063] In order to enable those skilled in the art to better understand the scheme of the present disclosure, the technical scheme in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present disclosure.

[0064] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein.

[0065] As discussed in the previous background technology, in the traditional pickled mustard tuber pickling process, the control of the brine transfer system is in a semi-automatic state, and if it is desired to automatically control the brine scheduling of the brine transfer system, a thorough interlocking protection mechanism is required to ensure the correct scheduling and operating efficiency of the brine transfer system. However, due to the large number of scheduling paths and the existence of cross-functional pools, it is a complicated process to automatically interlock the multiple valves of the brine transfer system.

[0066] To this end, the concept of the present invention is to simplify the complex problem of automatic interlocking protection by turning the disorder of numerous saltwater pools and their valves into order, and grouping the ordered saltwater pools to form nodes, and controlling whether the inlet valve and outlet valve of the saltwater pool in the node are opened by polling the nodes, thereby realizing automatic control of the brine transfer system.

[0067] Before describing the automatic control of multiple valves for controlling the pickled vegetable brine transfer system according to the present disclosure, the design concept of the automatic control of the present disclosure is generally summarized to facilitate a better understanding of the technical content of the present disclosure.

[0068] Figure 2 FIG. 1 is a simplified schematic diagram of a pickled vegetable brine transport system according to an embodiment of the present disclosure. Figure 2As shown, the pickled vegetable brine transport system includes n pickling pools P, a plurality of brine supply pipes A0, A2, A4, B0, B2, B4, etc. for supplying brine to each pickling pool P, a plurality of brine discharge pipes A1, A3, A5, C2, C4, B1, B3, B5, D2, D4, etc. for discharging the brine from each pickling pool, and a plurality of transfer units (arranged in Figure 2 In the area indicated by R3 shown in the figure, multiple transfer units form a single transfer node, each saltwater tank includes an inlet valve PI for controlling the entry of brine and an outlet valve PO for controlling the discharge of brine, the brine supply pipe is connected to the inlet valve PI of the saltwater tank, and the brine discharge pipe is connected to the outlet valve PO of the saltwater tank.

[0069] like Figure 2 As shown, the pickled vegetable brine transport system includes a first area R1 (e.g., a south area or a north area), a second area R2 (e.g., a north area or a south area) and a third area R3 located between the first area R1 and the second area R2, n pickling pools are distributed in the first area R1 and the second area R2, and a plurality of transfer units are distributed and included in the third area R3. In the concept of the present disclosure, a plurality of first brine supply pipes A0, A2, A4, etc. and a plurality of first brine discharge pipes A1, A3, A5, C2, C4, etc. are divided into the first area R1, and a plurality of second brine supply pipes B0, B2, B4, etc. and a plurality of second brine discharge pipes B1, B3, B5, D2, D4, etc. are divided into the second area R2.

[0070] The above is the overall design concept of the present disclosure. Figure 2 and Figure 3 A control method for controlling multiple valves of a pickled vegetable brine transport system according to an embodiment of the present disclosure is described, wherein Figure 3 The present invention is a method for controlling multiple valves of a pickled vegetable brine transfer system according to an embodiment of the present disclosure.

[0071] like Figure 3 As shown, the control method may include:

[0072] Step S100: allocating a pickle pool index for identifying the pickle pool to each pickle pool.

[0073] like Figure 4 As shown, as an example, the pickled pool may include 108 pickled pools, of which the number of first pickled pools as universal pickled pools is 60, the number of second and third pickled pools as ordinary pickled pools is 48, and a pickled pool index for identifying the pickled pool is assigned to each of the 108 pickled pools, for example, a continuous natural number 1, 2, 3 ... 108. The pickled pool index is not limited to the example shown here, and other pickled pool indexes can be used as long as polling can be convenient.

[0074] It should be noted that the first pickling tank and the second and third pickling tanks are common terms in the technical field of pickled mustard tuber, and those skilled in the art can understand the functions to be achieved by the first pickling tank and the second and third pickling tanks. This article does not involve the modification of the functions and configurations of the pickling tanks. Therefore, the functions to be performed by the first pickling tank and the second and third pickling tanks will not be described in detail here to obscure the inventive point of the present disclosure.

[0075] Step S102, dividing the n pickling pools into m groups according to the pickling pool index, each group forming a node and including s pickling pools, at least two nodes share a brine supply pipeline, at least two nodes share several brine discharge pipelines of the multiple brine discharge pipelines, wherein s, n and m are non-zero integers.

[0076] like Figure 2 As shown, as an example, three pickled pools can be formed into one group. In the case where the pickled pools include 108 pickled pools, a total of 36 groups are formed, thereby forming 36 nodes. Figure 2 In the example, two nodes share a brine supply pipeline, for example, Figure 2 The nodes N1 and N2 shown share a brine supply pipe A0, and four nodes or two nodes share a plurality of brine discharge pipes, for example, Figure 2 The nodes N1 , N2 , N3 and N4 shown share a plurality of brine discharge pipes, among which the brine discharge pipe A0 is schematically indicated, thereby making the design of the path of the brine discharge pipe simpler and the structure more compact.

[0077] Step S104, assigning an inlet valve index and an outlet valve index to the inlet valve and the outlet valve of the pickling pool, wherein the inlet valve index and the outlet valve index of each pickling pool are associated with the pickling pool index of the pickling pool.

[0078] like Figure 5 As shown, FUT1 and DUT1 respectively indicate the inlet valve and outlet valve of the pickling pool with pickling pool index 1. Correspondingly, the inlet valve index of the inlet valve of the pickling pool with pickling pool index 1 is ICM1.1 and the outlet valve index of its outlet valve is ICM2.1. For other pickling pools, the same applies.

[0079] Optional step S105, storing the pickling pool index in the memory; storing the inlet valve index and the outlet valve index in the memory; storing multiple transfer paths based on multiple recipe modes of the pickled vegetable brine transfer system in the memory.

[0080] Step S106, determining a recipe mode indicating a recipe of a pickled vegetable brine transfer system.

[0081] As an example, the formula pattern indicating the recipe of the pickled vegetable brine transport system is mainly based on which functional pool the brine is to pass through, i.e., the sewage pool, the filtration pool, the high-concentration brine pool, the low-concentration brine pool, the pure water pool, the sewage main pipeline and the cleaning pipeline, so that the formula pattern can at least include, for example, a sewage discharge mode, a brine circulation mode, a brine collection mode, a brine usage mode, a cleaning mode and a water replenishment mode.

[0082] Step S108, determining the transportation route of the brine based on the recipe model, the transportation route includes the source salting tank, the transfer units to be passed through, and the destination.

[0083] Specifically, in step S108, based on the recipe mode to be executed, the transfer path corresponding to the recipe mode to be executed can be searched from the memory, and the pickling pool index of the source pickling pool and the inlet valve index and outlet valve index of the source pickling pool can be queried from the memory according to the transfer path. As an example, the source pickling pool includes a pickling pool and a second and third pickling pool, the transfer unit includes the above-mentioned functional pool, and the destination can include the pickling pool and the transfer unit. For example, when the salt water is discharged to the sewage station through the sewage main, the destination can be the sewage main as the transfer unit.

[0084] Step S110, based on the determined pickling pool index of the source pickling pool and the inlet valve index and outlet valve index of the source pickling pool, polling of multiple nodes is performed to control the inlet valve and outlet valve of the source pickling pool to open and the inlet valve and outlet valve of the pickling pools other than the source pickling pool to close.

[0085] In the control method disclosed in the present invention, the disorder of numerous pickling pools and valves of the pickling pools is transformed into order, and the ordered pickling pools are grouped to form nodes, and the nodes are polled as a loop, so that the amount of code can be minimized, and it is also possible to prepare for later expansions such as adding reserved interfaces to the pickling pools, which are then filled in according to the designed rules, greatly shortening the time for testing such as modifying old paths or adding new paths caused by adding pickling pools in the later stage.

[0086] As an embodiment, step S104 may also include allocating inlet valve addresses to the inlet valves of the n pickling pools in a first order, the inlet valve addresses and the inlet valve indexes are mapped to each other; allocating outlet valve addresses to the outlet valves of the n pickling pools in a second order, the outlet valve addresses and the outlet valve indexes are mapped to each other, and the sorting method of the first order is different from the sorting method of the second order. Therefore, in this embodiment, step S110 may include generating a plurality of control signals associated with each transfer unit based on the transfer processing performed by the plurality of transfer units; combining the plurality of control signals to generate a valve control command; addressing the outlet valve address or the inlet valve address of the pickling pool by converting the valve control command to the corresponding outlet valve address or the corresponding inlet valve address; controlling the opening of the inlet valve of the pickling pool having the addressed inlet valve address and the opening of the outlet valve of the pickling pool having the addressed outlet valve address.

[0087] As an example, combining the plurality of control signals to generate the valve control command includes: combining the plurality of control signals in an OR operation.

[0088] In this embodiment, the valves of the 108 salting tanks are controlled by polling plus indirect addressing, so that the automation control becomes more simplified and the opening of the valves can be accurately controlled.

[0089] As an embodiment, step S110 may include: identifying the node where the source salting tank is located as an activated node, wherein the node excluding the source salting tank is identified as an inactivated node; identifying a first inactivated node that shares a brine supply pipeline with the source salting tank and a second inactivated node that shares several brine discharge pipelines with the source salting tank among the inactivated nodes; and controlling the inlet valves and outlet valves of other salting tanks in the activated node except the source salting tank to be closed, and controlling the inlet valve of the salting tank in the first inactivated node to be closed and the outlet valve of the salting tank in the second inactivated node to be closed.

[0090] Specifically, Figure 2 As shown, if the source salting pool is determined to be the salting pool P indicated by P based on the transport path, the node N1 where the salting pool P is located is identified as an activated node, so the node N2 that shares the salt water supply pipeline A0 with the node N1 will be identified as the first inactivated node, and the nodes N2, N3 and N4 that share several salt water discharge pipelines with the node N1 (as an example and for convenience of description, A1 indicates one salt water discharge pipeline) are identified as the second inactivated node. Therefore, the inlet valve and outlet valve of other salting pools except the source salting pool P in the activated node N1 can be controlled to be closed, and the inlet valves of all salting pools in the first inactivated node (for example, N2) can be controlled to be closed, and the outlet valves of all salting pools in the second inactivated node (for example, N2, N3 and N4) can be controlled to be closed. This can reduce the amount of code and the amount of calculation.

[0091] As an example, at least two nodes share several brine discharge pipes, including at least four nodes share several brine discharge pipes. For the case where at least two nodes share one brine supply pipe and at least four nodes share several brine discharge pipes, step S102 may also include: forming a first parent node PA1 with at least two nodes N1 and N2 that share one brine supply pipe; forming a second parent node PB1 with at least four nodes N1, N2, N3 and N4 that share several brine discharge pipes; determining the first parent node PA1 and the second parent node PB1 where the source salting pool is located; polling multiple first parent nodes PA1 to control the inlet valves of the salting pools in all other first parent nodes other than the first parent node (indicated by PA1) where the source salting pool is located to be closed; and polling multiple second parent nodes to determine that the outlet valves of the salting pools in all other second parent nodes other than the second parent node (indicated by PB1) where the source salting pool is located are closed. Here, the first parent node and the second parent node include the same node where the source salting pool is located, such as the node N1 shown in this example.

[0092] Further, after polling the parent node, step S102 also includes polling the nodes in the first parent node where the source pickling pool is located (i.e., nodes N1 and N2) to control the closure of the inlet valve of the pickling pool in the node (N2) outside the activation node where the source pickling pool is located; and polling the nodes in the second parent node where the source pickling pool is located (i.e., nodes N1, N2, N3 and N4) to control the closure of the outlet valve of the pickling pool in the nodes outside the activation node where the source pickling pool is located (i.e., nodes N2, N3 and N4).

[0093] In this way, chain protection can be based on large (parent) nodes and small nodes to perform individual interlocking protection and splicing combination interlocking protection, making interlocking protection simpler and requiring less code.

[0094] Alternatively, if Figure 3 As shown, the control method may further include: step S112, forming a common node from the plurality of transfer units, the common node including a plurality of branch transfer pipelines connected to the plurality of first brine supply pipelines and the plurality of second brine supply pipelines and the plurality of first brine discharge pipelines and the plurality of second brine discharge pipelines, each of the plurality of branch transfer pipelines including a control valve for controlling the flow of brine into the branch transfer pipeline, such as Figure 6 As shown, it shows a schematic diagram of the third area (i.e., the common node formed) of the brine transfer system according to an embodiment of the present disclosure; and step S114, controlling the opening of the control valves of the corresponding branch transfer pipelines in the multiple branch transfer pipelines according to the transfer path determined based on the recipe pattern.

[0095] Specifically, Figure 6As shown, each of the multiple transfer units (for example, the transfer unit indicated by label M (for example, it can be assigned index M21)) is connected to a plurality of first brine supply pipes and a plurality of second brine supply pipes and a plurality of first brine discharge pipes and a plurality of second brine discharge pipes through a plurality of branch transfer pipes, and the transfer unit M includes an inlet valve for controlling the entry of brine into the transfer unit and an outlet valve for controlling the discharge of brine.

[0096] As an example, step S114 may also include determining the brine discharge pipe through which the brine discharged from the source salting tank passes based on the recipe mode. As an example, Figure 6 In the embodiment, the transfer unit M is connected to the brine discharge pipeline A3. According to the determined brine discharge pipeline, the opening of the control valve of the corresponding branch transfer pipeline in the plurality of branch transfer pipelines is controlled; and the opening of the inlet valve and the outlet valve of the transfer unit to be passed is controlled.

[0097] As an example, Figure 7 As shown, the transfer path includes a first transfer path TR2 from a first brine discharge pipe of a first area through a transfer unit and a second transfer path TR1 from a brine discharge pipe of a second area through a transfer unit.

[0098] Therefore, step S114 may also include determining whether the first transfer path or the second transfer path is selected as the transfer path; and determining a series of branch transfer pipelines that the transfer path passes through in sequence from the determined saline discharge pipeline according to the determination result. Step S114 may further include sequentially opening the control valves on the series of branch transfer pipelines arranged from the determined saline discharge pipeline according to the opening state of the control valve on the determined saline discharge pipeline.

[0099] Therefore, it is possible to control many branch paths in the transit node through the method of upstream transmission and downstream inheritance, so that the chain protection mechanism can be completed in a very large number of paths in a simple manner.

[0100] The above is a specific control process of the control method for controlling multiple valves of the pickled vegetable brine transfer system according to the embodiment of the present disclosure. The control method can realize the automatic scheduling of the brine transfer system, thereby greatly improving the production efficiency and operation safety. By reducing manual operations, not only the production speed is improved, but also by accurately controlling valves and paths, cross contamination of materials and equipment damage are effectively prevented, thereby reducing the risk of production accidents.

In this example, after determining the recipe mode of the pickled vegetable brine transfer system based on the input data input by the operator, the determination unit 203 queries the transfer path corresponding to the recipe mode from the memory 205 according to the recipe mode, thereby determining the transfer path of the brine in the current mode.

[0107] As an example, the polling control unit 204 can also be configured to query the pickling pool index from the memory 205 based on the determined source pickling pool and query the inlet valve index and outlet valve index of the source pickling pool from the memory 205; and control the opening of the inlet valve and outlet valve of the source pickling pool according to the pickling pool index of the source pickling pool and the inlet valve index and outlet valve index of the source pickling pool.

[0113] The polling control unit 204 can also be configured to: poll the nodes included in the first parent node where the source salting pool is located to control the inlet valve of the salting pool in the first non-activated node to close; and poll the nodes included in the second parent node where the source salting pool is located to control the outlet valve of the salting pool in the second non-activated node to close. The node where the source salting pool is located is used as an activated node, and the node of the source salting pool is not included as an inactive node. The inactive nodes include a first inactive node that shares a brine supply pipeline with the source salting pool and a second inactive node that shares several brine discharge pipelines with the source salting pool.

[0114] As an example, the grouping unit 202 can also be configured to: form a common node with multiple transfer units, the common node includes a plurality of branch transfer pipelines connected to a plurality of first brine supply pipelines and a plurality of second brine supply pipelines and a plurality of first brine discharge pipelines and a plurality of second brine discharge pipelines, each of the plurality of branch transfer pipelines includes a control valve for controlling the flow of brine into the branch transfer pipeline.

[0115] As an embodiment, the polling control unit 204 can also be configured to control the opening of the control valve of the corresponding branch transfer pipeline in the multiple branch transfer pipelines according to the transfer path determined based on the recipe mode. Specifically, the polling control unit 204 can be configured to determine the brine discharge pipeline through which the brine discharged from the source salting tank passes based on the recipe mode; control the opening of the control valve of the corresponding branch transfer pipeline in the multiple branch transfer pipelines according to the determined brine discharge pipeline; and control the opening of the inlet valve and the outlet valve of the transfer unit to be passed.
