[0029] First, some nouns or terms appearing in the process of explaining the embodiments of the present application are applicable to the following explanations:

In the embodiments of the present application, the real-time database includes real position numbers and virtual position numbers.

[0032] Real position number: the position number in the industrial production process refers to the data monitoring point in the field.

[0046] Under the above-mentioned operating environment, the embodiments of the present application provide a loop state determination method embodiment. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a group of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in an order different from that shown.

[0047] Figure 2is a flowchart of a loop state determination method according to an embodiment of the present application, as shown in the figure, the method comprises the following steps: Figure 2

[0048] In step S202, a target loop is created, wherein the target loop is a loop in the industrial control process, and the target loop comprises at least one virtual device corresponding to an entity device.

[0049] In step S202, in order to facilitate the control of the entity production device, the virtual devices are usually configured in the corresponding control software, so that the connection relationship between the configured virtual devices is the same as the connection relationship between the entity production devices. After the virtual devices are configured, the target loop is determined according to different virtual devices, and the number of the target loop is at least one.

[0050] In step S204, a condition met by the target loop in the industrial control process is determined in response to a first instruction of a target object.

[0051] In step S204, the user sets the condition met by the target loop through the first instruction according to the created target loop. Specifically, since the target loop is composed of virtual devices corresponding to entity devices, the condition met by the entire target loop in the industrial control process can be determined by setting the conditions of the virtual devices in the target loop. It should be noted that the setting of the condition can be embodied by different logical expressions. For example, condition 1 corresponding to virtual device 1 is determined by logical expression 1, condition 2 corresponding to virtual device 2 is determined by logical expression 2, and so on. According to the conditions corresponding to all virtual devices in the target loop, the logical expressions corresponding to different virtual devices are connected by a connection symbol, and then the logical expression met by the target loop in the industrial control process can be determined.

[0052] In step S206, the state information of the target loop is determined according to the condition in the case where the condition is verified to be correct.

[0053] In step S206, after the condition met by the target loop is determined, that is, after the logical expression corresponding to the target loop is determined, the condition (or the logical expression) needs to be verified. After the verification is passed, it indicates that the condition setting in the target loop is successful, and then the state information of the virtual devices in the target loop can be determined according to the condition set in the target loop. The state information can indicate whether the virtual devices in the target loop are abnormal.

[0054] ​In the steps S202 to S206, after the target loop is created, the condition (i.e., the logical expression) of the virtual device in the target loop is set, and then the condition (or the logical expression) satisfied by the target loop is determined according to the condition corresponding to the virtual device, so that the long-term statistical automatic control rate and stability rate calculation requirements are met, the workload and error rate are reduced. The user inputs different forms of logical expressions for combination according to the characteristics of each loop (i.e., different conditions corresponding to the virtual devices in the loop), and the user only needs to configure the logical expression once. After the configuration is successful, the evaluation results of the PID performance evaluation product on the automatic control rate and the stability rate are improved, the automatic control rate and the stability rate are accurately calculated, the user can accurately locate the use of the production device, and thus the industrial control process is more convenient and efficient.

[0055] In the step S202 of the loop state determination method, the target loop is created, specifically including the following steps: in response to a first operation of a target object, determining the virtual devices required by the target loop; and connecting the virtual devices to obtain the target loop.

[0056] In the embodiments of the present application, the target object (i.e., the user) selects the virtual devices required in the target loop through the first operation, connects the selected virtual devices, and obtains a target loop.

[0057] In the step S204 of the loop state determination method, the condition satisfied by the target loop in the industrial control process is determined, specifically including the following processes: determining the first condition corresponding to each virtual device in the target loop, wherein the condition at least includes the bit number corresponding to the virtual device, the preset value corresponding to the virtual device, and the symbol connecting the bit number and the preset value; in the case where the number of the first conditions is greater than 1, determining the connector between the plurality of first conditions; and determining the condition satisfied by the target loop in the industrial control process according to the first condition and the connector.

[0058] In the step S204 of the loop state determination method, after the condition satisfied by the target loop in the industrial control process is determined, the method further includes the following step: verifying whether the setting of the condition is correct.

[0059] In the loop state determination method, verifying whether the setting of the condition is correct specifically includes the following steps: obtaining the actual value range corresponding to each virtual device in the target loop; and when the preset value of each virtual device is within the actual value range corresponding to each virtual device, generating a prompt information, wherein the prompt information is used to indicate that the condition setting is correct.

[0060] In the loop state determination method, after the prompt information is generated, the method further comprises: in response to a second instruction of the target object, configuring a condition met by the other loop in the industrial control process, wherein the second instruction is used to copy the condition met by the target loop in the industrial control process to the other loop for use, and the other loop is a loop different from the target loop in the industrial control process; and modifying the condition obtained by copying by the other loop according to a third instruction of the target object.

[0061] In the embodiments of the present application, the user can determine the first condition corresponding to each virtual device in the target loop according to the business requirement, i.e., set the logical expression corresponding to each virtual device in the target loop, which is composed of the bit number corresponding to the virtual device, the preset value corresponding to the virtual device, and the symbol used to connect the bit number and the preset value. Each virtual device corresponds to a bit number, for example, the bit number corresponding to the virtual device 1 is PIC1701.

[0062] In Figure 3a In the expression configuration interface shown in the figure, the user can maintain the logical expression data in the system interface according to the business requirement and input the corresponding data information.

[0063] Firstly, the bit number name corresponding to the virtual device is input, for example, the bit number PIC1701 corresponding to the virtual device 1 is input in the operation menu.

[0064] Secondly, the symbol is selected, and in the embodiments of the present application, the symbols supported by the system include greater than ( > ), less than ( < ), less than or equal to ( <= ), greater than or equal to ( >= ), equal to ( = ), and not equal to ( <> ).

[0065] Thirdly, the preset value corresponding to the virtual device is input, which is manually input by the user, for example, the preset value 1 is input.

[0066] Fourthly, the connector or conjunction word between the logical expressions corresponding to different virtual devices is selected, including and ( & ) and or ( || ).

[0067] Fifthly, the logical expression (referred to as expression, i.e., the first condition) corresponding to the virtual device is verified by clicking the "add" button to determine whether the first condition is input correctly, and the verification process can also verify whether the set logical expression is correct in logic, i.e., whether there is a contradiction between the expressions. The expression corresponding to the virtual device that passes the verification is displayed in the expression box in the middle of the interface shown in the figure and below the interface, and the previously set expression corresponding to the virtual device can be edited or deleted through the "edit" and "delete" buttons in the box below the interface. Figure 3a Figure 3a ​The interface displays the partially set expressions, such as: PIC1701>1&, PIC1701A<10&, PIC1741<=100&, PIC1741A>=10&, PIC1761=0||, PIC1841<=10&, PIC1841A>=1&, PIC1884<>6&, PIC1761<=20, and the complete expression composed of the above partial expressions is displayed in the expression box in the middle of the interface, and the complete expression is as follows:

[0068] PIC1701>1&PIC1701A<10&PIC1741<=100&PIC1741A>=10&PIC1761=0||PIC1841<=10&PIC1841A>=1&PIC1884<>6&PIC1761<=20

[0069] In the sixth step, if the expression corresponding to the virtual device is to be continuously added, the first step is returned to; if the expression is not to be continuously added, the next step is jumped to, and the expression in the loop is verified through the "expression verification" button.

[0070] In the seventh step, after the expression corresponding to each virtual device in the loop is set, the different expressions are connected by the connector, so that the complete expression corresponding to the target loop is obtained, and the complete expression indicates the condition met by the target loop in the industrial control process.

[0071] After the complete expression corresponding to the target loop is obtained, the complete expression is verified through the "expression verification" button, so as to determine whether the setting of the complete expression is correct and whether the configuration is successful.

[0072] In the eighth step, the complete expression is copied. First, it is determined whether the complete expression needs to be copied to other loops. If other loops need it, the complete expression can be copied to other loops for use by clicking the "copy expression" button in the interface. Figure 3a If other loops do not need the complete expression set in the target loop, the next step is jumped to.

[0073] If the user clicks the "copy expression" button, the interface as shown in Figure 3b is popped up. In the interface as shown in Figure 3b , the left side is different grouping structures, including flow, pressure, liquid level, temperature, mass, other grouping, etc. The basic information of the grouping on the right upper side includes name and description. It should be noted that root is the default root node of all groupings. In the interface as shown in Figure 3bIn the diagram shown, each loop corresponds to a loop name. Loops can be queried by name, or copied expressions can be applied to the selected loop based on its name. To simplify the operation, in Figure 3b There are two buttons: "Select All" and "Deselect All". Clicking the "Select All" button will select all circuits in the list, and clicking the "Deselect All" button will deselect the selected circuits in the list. Clicking the "OK" button will execute the corresponding copy operation, and clicking the "Cancel" button will cancel the copy operation.

[0074] Step 9, by clicking Figure 3a Clicking the "OK" or "Apply" button on the interface will apply the complete expression set for the target loop; clicking the "Cancel" button will disable the expression. Alternatively, you can click the "Previous" or "Next" button in the lower left corner of the interface to set the expression for the previous or next loop.

[0075] In step S206 of the above method for determining the state of a loop, determining the state information of the target loop based on conditions includes: acquiring the data value corresponding to the virtual device in the target loop; determining the state information of the target loop based on the data value and the conditions corresponding to the target loop; acquiring valid data from the data value when the state information indicates that the target loop is in operation; and evaluating the target loop based on the valid data.

[0076] In this embodiment of the application, the data value corresponding to the virtual device in the target loop is obtained, that is, the real-time data value of the tag number is read according to the tag number corresponding to the virtual device. The status information of the target loop is determined according to the logical expression corresponding to the target loop. The status information includes start-up and stop-up. When the status information indicates that the target loop is in the start-up state, the automatic control rate and stability rate are calculated by obtaining the valid data in the data value, and the target loop is evaluated.

[0077] In this embodiment, the formulas for the self-control rate and the stability rate are as follows:

[0078]

[0079]

[0080] Through the above steps, the purpose of quickly determining the state information of the target loop according to the condition met by the target loop can be achieved, so that the technical effect of improving work efficiency is realized. Compared with frequently judging whether the loop state is abnormal by manual, manually removing abnormal working condition data, and manually calculating the automatic control rate and the stability rate, the present application quickly and accurately judges whether the logical expression input by the user is correct by using the logical expression, so that the evaluation result of the PID performance evaluation product is improved, the automatic control rate and the stability rate are accurately calculated, the user can accurately locate the equipment usage, and the monitoring capability of the loop is greatly improved.

[0095] Figure 6 This is a flowchart of a loop evaluation according to an embodiment of this application, such as... Figure 6 As shown, to facilitate the control of physical production equipment, virtual devices typically need to be configured in the corresponding control software so that the connection relationships between the configured virtual devices are the same as those between the physical production equipment. After configuring the virtual devices, different loops are created based on the different loops formed by the different virtual devices. Different conditions can be set for virtual devices in different loops. These conditions can be set using the corresponding tag number of the virtual device. For example, if the tag number for virtual device 1 is PIC1701, then condition 1 for virtual device 1 is set to PIC1701>10; if the tag number for virtual device 2 is PIC1702, then condition 2 for virtual device 2 is set to PIC1702<100; if the tag number for virtual device 3 is PIC1703, then condition 3 for virtual device 3 is set to PIC1703>=20; if the tag number for virtual device 4 is PIC1704, then condition 4 for virtual device 4 is set to PIC1704<=98; if the tag number for virtual device 5 is PIC1705, then condition 5 for virtual device 5 is set to PIC1705<>10; and the condition for virtual device n is set to n. Different connectors are used to connect the conditions corresponding to different virtual devices. Figure 6In the shown schematic diagram, the conditions between condition 1 and condition 2, between condition 2 and condition 3, between condition 4 and condition 5, and between condition 5 and condition n are connected by the connection symbol “&”, and the conditions between condition 3 and condition 4 are connected by the connection symbol “||”. The conditions corresponding to different virtual devices in the same loop are connected by the connection symbol, and then the condition (i.e., the expression) corresponding to the loop is obtained. The conditions in the expression are all self-defined, and then the self-defined conditions (or expressions) are verified. When the condition verification is successful, the configuration ends, and the expression can take effect in the loop. If the verification fails, the step of setting the conditions needs to be returned to be reset until the configuration ends when the condition verification is successful.

[0096] After the configuration of different loops ends, the loops can be periodically evaluated. First, the loop to be evaluated is selected, the self-defined condition (i.e., the logical expression) corresponding to the loop is determined, the state of the loop is determined according to the condition corresponding to the loop, when the loop state indicates that the loop is in the startup state, the real-time data value read by the bit number corresponding to the virtual device in the loop is obtained, the valid data in the data value is obtained, and then the automatic control rate, the stable rate, and the operation rate are calculated to obtain the evaluation result, and the evaluation ends. When the loop state indicates that the loop is not in the startup state, the evaluation process ends.
