Technical Field
The present disclosure relates to the field of automated control systems, and more particularly, to methods, systems, and controllers for controlling one or more industrial devices.
Background
In industrial processes, it is often necessary to manually open or stop an industrial device or open or close a valve when a measured parameter of the industrial device reaches a predetermined value or a trigger condition. However, manual operation often results in improper operation, untimely operation, and high labor cost. More automatic and flexible automatic control techniques need to be considered.
Disclosure of Invention
Technical problem
In an automatic Control System, such as a Distributed Control System (DCS), generally, a cause-and-effect relationship between a trigger condition and an execution action can be manually established by building a Control logic circuit and a series of operations such as programming, and the establishment of such a cause-and-effect relationship is generally single and fixed. However, once a cause and effect change is required, the control logic circuit needs to be manually modified and programmed accordingly. Therefore, the manual operation is complex, the workload is large, the operation efficiency is low, and the use and maintenance are not flexible.

Advantageous effects
According to the method, the system and the controller provided by the disclosure, a control logic circuit does not need to be manually and repeatedly established and correspondingly programmed to establish a new causal relationship or maintain an old causal relationship, the causal relationship can be established or maintained by establishing a virtual link through inputting the relationship between the representation reason and the result, and when the causal relationship is required to be modified, the control logic circuit does not need to be modified or correspondingly programmed, but information representing whether the relationship exists between the representation reason and the result is modified to automatically add or delete the virtual link representing the causal relationship based on the information, so that the establishment and modification process of the causal relationship is simplified, and the operation convenience and the operation efficiency are improved.

Detailed Description
Reference will now be made in detail to the present embodiments of the invention, examples of which are illustrated in the accompanying drawings. While the invention will be described in conjunction with the specific embodiments, it will be understood that they are not intended to limit the invention to the embodiments described. On the contrary, it is intended to cover alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims. It should be noted that the method steps described herein may be implemented by any functional block or functional arrangement, and that any functional block or functional arrangement may be implemented as a physical entity or a logical entity, or a combination of both.
It will be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed herein could be termed a second element, component, region, layer or section without departing from the spirit and scope of the present inventive concept.
Embodiments of the inventive concept will be described in detail and clearly below to the extent that the inventive concept can be easily implemented by those skilled in the art.
Note that the example to be described next is only a specific example, and is not to be construed as limiting the embodiments of the present invention necessarily to the specific shapes, hardware, connections, steps, numerical values, conditions, data, orders, and the like shown and described. Those skilled in the art can, upon reading this specification, utilize the concepts of the present invention to construct more embodiments than those specifically described herein.
In order to avoid the low safety and inconvenience of manual operation, an automatic control system such as DCS is used in many industrial processes to realize interlocking control of one or more industrial devices or hardware, which is a coordinated control manner in which when a certain parameter reaches a specified value or a certain device is turned on, off or turned on, off, the control of another device is linked or locked.
In an automatic control system, there are causes associated with one or more industrial devices and results associated with one or more industrial devices. The reason here may refer to a triggering reason, which indicates a triggering condition, e.g., a high air pressure, that is satisfied by a plurality of parameters of one or more industrial devices measured by a measuring device, such as a meter, in an automatic control system. Also, the results herein may refer to performing an action that represents an operation of one or more industrial devices in the automated control system, such as opening a purge valve.
If the causal relationships are established by building up control logic circuits in a conventional manner, one or more "physical" links determined by the control logic circuits are formed between the causes and the effects to implement the interlocking control function. However, when a cause and effect relationship needs to be changed due to environmental conditions, equipment characteristics, and production requirements, one or more links must be added or deleted by modifying the control logic. And, after the control logic circuit is modified, a series of operations such as compiling, downloading, etc. are also performed to validate the modified control logic circuit. This process of modifying the cause and effect relationship results in a control logic circuit that is computationally inefficient, requires a large amount of programming effort, and is single, offline. How to simplify the process of establishing and modifying cause and effect relationships is a matter of consideration.
Fig. 1 is a schematic diagram illustrating an example scenario of a control system according to an embodiment of the present disclosure.
Included in the example scenario 100 of fig. 1 are one or more industrial devices 101, a measurement device 102, a controller 103, one or more industrial devices 104, and an operator interface 105. One or more industrial devices 101 may be devices in an industrial process or a portion thereof. The measurement device 102 may be a measurement device such as a pressure sensor, a temperature sensor, or the like. AOne or more industrial devices 104 can be devices or portions thereof controlled by a control system in an industrial process. Wherein one or more industrial plants 101 and one or more industrial plants 104 may belong to the same plant, for example, one or more industrial plants 101 are impellers of a material pump, and one or more industrial plants 104 are material pumps. Or may belong to different devices, for example, one or more industrial devices 101 are line protection devices and one or more industrial devices 104 are reclosers. Operator interface 105 may be, for example, SiemensWinCC (Windows Control Center) interface or(Windows) interfaces, etc. The foregoing is shown by way of example only, and is not limiting.
As shown in fig. 1, one or more industrial devices 101 can be connected to a measurement device 102 to measure parameters of the one or more industrial devices 101 by the measurement device 102. The controller 103 can monitor one or more parameters of the industrial equipment 101 measured by the measurement device 102. Then, the controller 103 may determine whether these parameters satisfy a certain condition as a cause, for example, whether the air pressure reaches high. The controller 103 can be coupled to the one or more industrial devices 104 and output instructions by the controller 103 to the one or more industrial devices 104 to control the one or more industrial devices 104 to perform a resulting action, such as opening a purge valve.
It is determined by the controller 103 whether a relationship exists between which cause is associated with the measured parameter of the one or more industrial devices 101 and which outcome is associated with the action of the one or more industrial devices 104. The user can input information indicating the relationship between the cause and the result on the operation interface 105, and the operation interface 105 can provide the information to the controller 103.
The controller 103 may establish a virtual link between the cause and the result based on this information. Specifically, for example, the controller 103 may convert the information into a link code representing a relationship between the plurality of first causes and the plurality of first results, based on the information. The controller 103 may then establish a plurality of virtual links between the plurality of causes and the plurality of outcomes based on the link encoding.
When a certain reason is determined to be satisfied, the corresponding result is determined based on the plurality of virtual links, and one or more industrial devices are controlled to execute the action associated with the corresponding result.
For example, information on the relationship between the excessively short operation time (cause) of the line protection device and the reclosing non-operation (result) is received from the operation interface 105, and the controller 103 establishes a virtual link between the cause and the result based on the information. When the reason is satisfied (that is, the operation time of the line protection device is too short), the controller 103 controls the reclosing not to operate. The operation interface 105 may be a touch screen, and may directly receive an input of a relationship of a cause and a result by a user through a touch to the touch screen. The operation interface 105 may be a display for display only, and only information indicating the relationship between the cause and the result is displayed without inputting the information thereon, and the input of the information may be directly performed on the controller 103. For example, the controller 103 may have an operation interface thereon, or a plurality of keys may be provided on the controller 103 for input. The foregoing is shown by way of example only, and is not limiting.
One embodiment of inputting information representing a relationship between a plurality of reasons and a plurality of results on an operation interface is described below in conjunction with fig. 2, but is not limited thereto.
FIG. 2 is a schematic diagram illustrating an example of a cause and effect matrix table according to an embodiment of the disclosure.
In one embodiment of the present disclosure, a cause and effect matrix table 201 may be displayed on the operator interface 200, wherein a plurality of causes may be located in one dimension of the cause and effect matrix table 201 and a plurality of results may be located in another dimension of the cause and effect matrix table 201. Also, each table in the cause and effect relationship matrix table 201 associates one cause of the plurality of causes and one effect of the plurality of effects. For example, as shown in FIG. 2, the dimensions of the rows of the cause and effect matrix table 201 may represent a plurality of causes and the dimensions of the columns of the cause and effect matrix table 201 may represent a plurality of effects. However, the disclosure is not limited thereto, and for example, the dimension of the row of the cause and effect matrix table 201 may represent a plurality of results, and the dimension of the column of the cause and effect matrix table may represent a plurality of causes.
Selection or non-selection of one or more tables in the cause and effect relationship matrix table 201 may be received on the operator interface 200. For example, as shown in FIG. 2, a check is made in one or more tables (e.g., table 202) in the cause and effect matrix table 201 to indicate a selection or a uncheck to indicate a non-selection. Wherein, the selection of a table may indicate that there is a relationship between the reason and the result associated with the table, and the non-selection (or deselection) of a table may indicate that there is no relationship between the reason and the result associated with the table. For example, as shown in fig. 2, a table 202 in which the cause 16 and the result 2 are associated with each other is checked to show that the cause 16 and the result 2 are related to each other, and when the cause 16 is satisfied, one or more industrial devices can be controlled to perform the operation associated with the result 2.
For security, for example, the operation interface may be set with authority, and only authorized users may operate the operation panel 200 or the cause and effect relationship matrix table. For example, an account and a password may be set, and the operation panel or the cause and effect relationship matrix table may be operated only when the correct account and password are input, but is not limited thereto. Furthermore, after completing the selection or non-selection of one or more tables in the cause and effect relationship matrix table, the operation of completing the selection or non-selection may be determined by, for example, clicking a completion button (not shown), but the above is merely shown as an example, and the disclosure is not limited thereto.
The selection or non-selection of one or more tables in the cause and effect matrix table received at the operator interface 200 may be provided to a controller interacting with the operator interface 200 for further processing, e.g., conversion to a link code representing a relationship between a plurality of causes and a plurality of outcomes. In one embodiment of the present disclosure, the link code may be represented in a binary code form, but is not limited thereto. As will also be described in detail later in connection with fig. 3.
In the example of the cause and effect relationship matrix table 201 shown in fig. 2, by representing the cause and effect relationship in the form of a matrix table displayed on the operation interface, the user is made to see the plurality of causes and the plurality of results and the relationship therebetween more intuitively and clearly. And a single 'entity' link is changed into a selectable bidirectional matrix, so that bidirectional selection between reasons and results and flexible matching of multiple reasons to multiple results are realized, and the modification of the cause-effect relationship is particularly convenient.
Fig. 3 is a schematic diagram illustrating an example of link coding with respect to fig. 2, according to an embodiment of the present disclosure.
As previously described, establishing a plurality of first virtual links between a plurality of reasons and a plurality of outcomes based on the input information may include: the information is converted into a link code representing a relationship between the plurality of causes and the plurality of outcomes. Then, a plurality of virtual links between the plurality of input logics corresponding to the plurality of causes and the plurality of output logics corresponding to the plurality of results are established according to the link coding.
In another embodiment of the present disclosure, for one result of M results, N-bit chain coding may be established according to whether respective relationships between the result and N causes exist, where M and N are positive integers, and the N-bit chain coding corresponds to the N causes one to one. As shown in fig. 2, there are 16 causes and 8 results in the cause and effect relationship matrix table 201, a 16-bit link code is established for each result, each bit of the link code indicates whether or not there is a relationship between each cause and the result, for example, if represented in the form of a binary code, it can be represented by "1" that there is a relationship between the cause and the result, and "0" that there is no relationship between the cause and the result, or vice versa. For example, assume that if the link code 1 in binary form for cause 1 is 0 … 011(N bits), then taking 11 the lowest 2 bits in the N-bit link code may indicate that there is a relationship between cause 1 and cause 2 and result 1, respectively. Then, from this link coding, 2 virtual links are established between cause 1 and cause 2 and result 1, respectively. Thus, 8 16-bit link codes can be established for the cause and effect matrix table 201 of FIG. 2. These 8 link codes may be established separately or simultaneously. Establishing a link code for each outcome, it can be easily identified which causes have a relationship with the respective outcome, so that the controller establishes a plurality of virtual links based on the link code.
As shown in fig. 3, link encodings 1-8 in binary form are established according to the cause and effect matrix table of fig. 2. Link code 1 of result 1 is 0000000000000011(16 bits), link code 2 of result 2 is 1010000010000000, link code 3 of result 3 is 0000000000000100, link code 4 of result 4 is 0000000010000000, link code 5 of result 5 is 0000000000100000, link code 6 of result 6 is 0000000000000000, link code 7 of result 7 is 0000000000000000, and link code 8 of result 8 is 0000000000000001. In this case, "1" indicates that there is a relationship between the cause and the result, and "0" indicates that there is no relationship between the cause and the result. Here, the low order bits to the high order bits of the link code correspond to the cause 1 to the cause 16 one to one, but the present invention is not limited to this, and the low order bits to the high order bits of the link code may correspond to the cause 16 to the cause 1 one to one, as long as there is a one-to-one correspondence relationship.
FIG. 4 is a schematic diagram illustrating an example of an online interlocking mechanism for establishing causal relationships, according to an embodiment of the present disclosure.
In one embodiment of the present disclosure, the establishment of a virtual link between a plurality of input logic corresponding to a plurality of reasons and a plurality of output logic corresponding to a plurality of results may be implemented in the controller 103.
Specifically, the controller 103 may build a (e.g., programmed) module 400 for causal relationships based directly on inputs received from the operator interface for the relationships between the causes and the effects, or based on link encodings derived from the relationship conversions of the inputs, a plurality of input pins (referred to as input logic, e.g., 401_1-N in fig. 4) of the module 400 may correspond one-to-one to a plurality of causes, and a plurality of output pins (also referred to as output logic, e.g., 402_1-M in fig. 4) of the module may correspond one-to-one to a plurality of effects. The input pin and the output pin may be implemented by a programming Language (e.g., Structured Control Language (SCL)).
Wherein one or more industrial devices may be measured by a measuring device, such as a meter, and the conditions satisfied by the measured parameters of the one or more industrial devices may be provided as a cause to the module 400 through the input pin. And, a plurality of results can be output to the execution control part of the corresponding action (for example, a software module of the execution module corresponding to the resulting action) through the module 400 to the output pin, so that the corresponding industrial equipment (which is connected with the controller or equipment (for example, a card) connected with the controller) executes the action corresponding to the result.
In an embodiment of the present disclosure, the module 400 is established by the controller 103. In another embodiment of the present disclosure, causal information or link coding representing the causal relationship may also be directly input to the module 400 to modify the input pins, output pins and virtual links between them.
Specifically, when module 400 receives information representing a relationship between a plurality of causes and a plurality of outcomes and the information is converted to a link code, a virtual link may be established between the causes and outcomes according to the link code (as shown by the dashed lines in fig. 4), e.g., by logic in module 400 (e.g., implemented in scripts) to determine whether a virtual link should be established based on the link code. That is, when the link encoding indicates that a relationship exists between the one or more reasons and the one or more outcomes, a virtual link may be established between the one or more reasons and the one or more outcomes for which a relationship exists. The establishment of the virtual link indicates that a relationship exists between the corresponding reason and the corresponding result, and once the corresponding reason is established, the corresponding result is caused, that is, the corresponding industrial equipment is caused to execute the action corresponding to the result. The causal relationships represented by the multiple dashed lines in fig. 4 are shown by way of example only, and are not limiting.
For example, according to the mechanism shown in FIG. 4, M N-bit chain encodings may be established for N input pins 401_1-N and M output pins 402_ 1-M. Assuming that it is represented in binary form and that the link code 1 for the output pin 402_1 is 0 … 011(N bits), the link code 1 may indicate that there is a relationship between the input pins 401_1 and 401_2 and the output pin 402_1, respectively, and then a virtual link is established between the input pins 401_1 and 401_2 and the output pin 402_ 1.
Figure 5A is a schematic diagram illustrating an example of a cascaded cause and effect matrix table according to an embodiment of the disclosure, and figure 5B is a schematic diagram illustrating an online interlocking mechanism of a cascade according to an embodiment of the disclosure.
First, the plurality of causes and the plurality of results shown in fig. 2 are referred to as a plurality of first causes and a plurality of first results. In one embodiment, the controller 103 may be further configured to: second information representing a relationship between the plurality of second causes and the plurality of second outcomes is received. As shown in fig. 5A, a second cause and effect matrix table 201 'is shown below the cause and effect matrix table of fig. 2 (referred to as a first cause and effect matrix table), and the position of the second cause and effect matrix table 201' is not limited thereto. Wherein the second reason may include at least one of a plurality of first results and a plurality of first reasons as shown in FIG. 2, the plurality of second results being associated with actions of the one or more industrial devices. That is, the first cause and/or the first result in the first cause and effect matrix table shown in fig. 2 may be a cause of another second cause and effect matrix table. For example, if a first cause in the first cause and effect matrix table is a high air pressure and the corresponding first effect may be opening the blow-off valve, then the high air pressure may trigger a second effect as a second cause in the second cause and effect matrix table, e.g. closing the inlet valve, or opening the blow-off valve may trigger a second effect as a second cause in the second cause and effect matrix table, e.g. stopping the conveyor belt.
The two cause and effect matrix tables may also be cascaded cause and effect matrix tables.
For example, as shown in fig. 5A, the cause 1 ' in the second cause and effect matrix table 201 ' may be the cause 1 of the first cause and effect matrix table 201 shown in fig. 2, the cause 2 ' in the second cause and effect matrix table 201 ' may be the cause 1 of the first cause and effect matrix table 201 shown in fig. 2, and the other causes 3 ' -16 ' in the second cause and effect matrix table 201 ' may also be from other measured parameters. Based on the second information received in the second cause and effect matrix table 201', a plurality of second virtual links between the plurality of second causes and the plurality of second effects may be established. When a second cause of the plurality of second causes is determined to be established, a corresponding second result may be determined based on the plurality of second virtual links, and the one or more industrial devices may be controlled to perform the action associated with the corresponding second result.
After receiving the first information on the relationship between the first cause and the first result and the second information on the relationship between the second cause and the second result from the first cause and the second cause matrix table 201 'of fig. 5A, the modules 500 and 500' for the cause and effect relationship and the virtual link may be established based on the link coding converted from the first information and the second information, as shown in fig. 5B.
