Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The method, the apparatus, the electronic device and the storage medium for monitoring industrial plc data according to the present invention are described with reference to fig. 1 to 3.
Fig. 1 is a schematic flow chart illustrating a monitoring method of industrial plc data according to the present invention, and referring to fig. 1, the method includes:
11. determining an operation instruction, and enabling a plc controller in the industrial control virtual system to control corresponding industrial control equipment in the industrial control virtual system according to the operation instruction, wherein the operation instruction comprises at least one control script file configured in advance;
12. and acquiring the plc data of the plc controller in real time by adopting an opc ua protocol, and displaying the plc data on a page.
For step 11 and step 12, it should be noted that, in the prior art, a scene such as partial intelligent manufacturing can already be simulated, and under the scene simulation, the operation of the industrial control machine in the scene can be realized on a computer. However, this requires a student to have a front-line operator skill and to perform complicated operations, and the industrial control scenarios in which simulation operations can be performed are very limited.
For this purpose, different operation instructions are configured in advance, and each operation instruction comprises at least one control script file. And each control script file corresponds to the operation process of the industrial control equipment. When one operation instruction comprises a plurality of control script files, the operation instruction is indicated to enable operation actions of a plurality of industrial control devices to be associated. The operation instruction can be acquired and recognized by triggering operation on a system interface of the industrial control virtual system.
After the operation command is determined, the plc controller in the industrial control virtual system receives the operation command. Programmable Logic controllers (plcs) employ a type of Programmable memory for storing programs therein, executing user-oriented instructions such as Logic operations, sequence control, timing, counting, and arithmetic operations, and controlling various types of machinery or manufacturing processes via digital or analog input/output. Therefore, the plc controller in the industrial control virtual system controls the corresponding industrial control equipment in the industrial control virtual system according to the operation instruction, so that the industrial control equipment performs operation action, and generates corresponding data, the data can be fed back to the plc controller, and the plc controller obtains the data as plc data for subsequent analysis processing.
In the invention, the plc data is used as bottom data, and the plc data of the plc controller can be collected in real time by adopting an opc ua protocol, and the plc data is displayed on a page. The OPC ua interface protocol includes the previous a & E, DA, OPC XML DA or HDA, uses only one address space to access all previous objects, and is not limited by WINDOWS platform because it is defined from above the transport layer scolet. By adopting the opc ua protocol, different types of data generated by each industrial control device can be unified, so that the data can be unified, and subsequent analysis and processing are facilitated.
The monitoring method of the industrial control plc data provided by the invention can enable the plc controller in the industrial control virtual system to control the corresponding industrial control equipment in the industrial control virtual system according to the control instruction formed by at least one control script file, and adopts the opc ua protocol to collect the plc data of the plc controller in real time, and displays the plc data on the page, thereby realizing the real-time monitoring of the simulation operation of the industrial control equipment and simultaneously avoiding the complex operation of manual work on the industrial control simulation environment.
In the further method of the above method, the explanation is mainly for the processing procedure of determining the operation instruction, which is specifically as follows:
and sensing a trigger signal on a system interface of the industrial control virtual system, and determining a corresponding operation instruction according to the trigger signal.
In this regard, it should be noted that, in the present invention, after the industrial control virtual system is constructed, the virtual connection of each industrial control device and the corresponding operation button of each industrial control device in different operation scenes can be viewed on the system interface of the industrial control virtual system. At this time, a student who is not familiar with the operation can trigger the corresponding operation button, and at this time, the terminal senses a trigger signal on a system interface of the industrial control virtual system, and then matches the trigger signal according to the operation content corresponding to the trigger information to obtain an operation instruction.
The method further comprises the step of determining a corresponding operation instruction according to the trigger signal by sensing the trigger signal on the system interface of the industrial control virtual system, so that the operability of the new student on the control of the industrial control equipment can be improved.
In the further method of the method, the scenes such as partial intelligent manufacturing can be simulated in the prior art, but the industrial control scenes for simulation operation are very limited. Therefore, the industrial control virtual system is constructed in a mode of combining a digital twin technology and a cloud virtual machine.

According to the method, an industrial control virtual system suitable for more scenes can be constructed in a mode of combining a digital twin technology and a cloud virtual machine, and the universality of simulation tests is improved.
In the further method of the above method, the explanation of the processing procedure of page display of plc data is mainly as follows:
and asynchronously updating the plc data to the database in real time, integrating and summarizing the plc data in the database, and displaying pages in a chart form.
In this regard, it should be noted that plc data collected in real time is asynchronously updated into the database, which means that a portion of a web page may be updated without reloading the entire page. And the terminal integrates and summarizes plc data in the database and displays pages in a chart form.
In addition, the list in the chart form can be used for seeing visual effects on an interface of an upper computer or a monitoring terminal.
