[0011] Optionally, in another embodiment of the method of the present application, after generating the third display screen for the user, the method further includes: When receiving a display stop instruction, clearing the stored SCADA data, and establishing an association relationship between the real-time SCADA data and the target service node; The association relationship is stored in the cache node.

[0013] According to another aspect of the embodiments of the present application, an electronic device is provided, including: A memory for storing executable instructions; and A display is used to execute the executable instructions with the memory to complete the operation of any of the above-mentioned SCADA data display methods for oil and gas pipeline networks.

[0014] According to another aspect of an embodiment of the present application, a computer-readable storage medium is provided for storing computer-readable instructions, and when the instructions are executed, the operations of any of the above-mentioned SCADA data display methods for oil and gas pipeline networks are performed.

[0015] In the present application, when a display instruction is received, a first display screen is generated for the user based on the SCADA data from each business node stored in its own cache node; at least one target business node of interest to the user is selected from each business node, and a transmission notification is sent to the target business node, the transmission notification is used to obtain the stored SCADA data stored in the target business node; after obtaining the stored SCADA data from the target business node, a second display screen is generated for the user based on the stored SCADA data; and, a collection notification is sent to the target business node, the collection notification is used to inform the target business node to collect SCADA data in real time, and transmit the collected real-time SCADA data to the cache node; based on the real-time SCADA data, a third display screen is generated for the user.

[0028] Combine the following Figure 1-Figure 2 To describe a SCADA data display method for an oil and gas pipeline network according to an exemplary embodiment of the present application. It should be noted that the following application scenarios are only shown to facilitate understanding of the spirit and principles of the present application, and the embodiments of the present application are not limited in this regard. On the contrary, the embodiments of the present application can be applied to any applicable scenario.

[0029] The present application also proposes a SCADA data display method and system for oil and gas pipeline networks.

[0030] Figure 1 The following schematically shows a flow chart of a SCADA data display method for an oil and gas pipeline network according to an embodiment of the present application. Figure 1 As shown, including: S101, upon receiving a display instruction, generating a first display screen for a user based on SCADA data from various service nodes stored in its own cache node.

[0031] S102, selecting at least one target business node that the user is interested in from each business node, and sending a transmission notification to the target business node, where the transmission notification is used to obtain the stored SCADA data stored in the target business node.

[0032] S103, after acquiring the stored SCADA data from the target business node, generating a second display screen for the user based on the stored SCADA data. Also, sending a collection notification to the target business node, the collection notification is used to inform the target business node to collect SCADA data in real time, and transmit the collected real-time SCADA data to the cache node.

[0033] S104, generating a third display screen for the user based on the real-time SCADA data.

[0034] In the related art, the SCADA system is a computer-based DCS and industrial automation monitoring system, that is, a data acquisition and monitoring system. In one way, the SCADA system can simply observe the industrial process, or control the industrial process, and has data collection and display functions, and has been developed in many industries.

[0035] In one way, SCADA systems are widely used in various industrial sectors and have become the most important part of industrial management systems. For example, SCADA systems can be used to monitor and collect data from one or more industrial equipment in a certain area in real time or periodically, and then collect the operation data, repair data, maintenance data, fault data, etc. of each industrial equipment.

[0036] In one way, since most of the SCADA data is industrial data, the amount of data is extremely large. In the related art, in order to show the operation status of the current SCADA system to users, it is usually necessary to display the working data collected from each industrial device in a certain drawing method.

[0037] However, since the storage nodes of the SCADA system in the related technology store massive SCADA data, this will not only increase the storage pressure of the storage nodes, but also cause the SCADA system to add a large amount of necessary or unnecessary SCADA data to the drawing during the drawing generation process. This also causes the SCADA system to have a problem of slow display screen generation due to the huge amount of data during the data display process.

[0038] Based on the above problems, the present application proposes a SCADA data display method for oil and gas pipeline networks, which can detect that each business node of the SCADA system has collected SCADA data, but does not immediately transmit all of it to the storage node of the SCADA system. Instead, in the subsequent process of displaying data to users, after detecting that the user is interested in the SCADA data of a certain business node, the data stored in the business node is called to display it to the user. And when it is confirmed again that the user has a display demand, the data collection function of the business node is immediately started, so that the SCADA data newly generated by the current business node can be displayed to the user.

[0039] It can be understood that the technical solution of the present application can avoid the problem of consuming a large amount of transmission resources and excessive storage pressure on the storage node caused by each business node transmitting a large amount of SCADA data to the storage node of the SCADA system. On the other hand, the steps of acquiring SCADA data in segments and displaying the screen in segments can also reduce the screen generation pressure of the SCADA system and reduce the disadvantage of wasting operating resources caused by showing the user pictures that are not of interest to the user unnecessarily.

[0040] Further, this application is hereby incorporated by reference Figure 2 Describe the plan in detail: Step 1: upon receiving a display instruction, obtain the corresponding data source information and data producer information in the SCADA data of each business node stored in its own cache node.

[0041] In one embodiment, the SCADA system in the embodiment of the present application may not store all the SCADA data of each business node in the storage node, but only store a small amount of SCADA data of each business node (the small amount of SCADA data at least includes the data source information and data producer information of the corresponding business node). It can be understood that this can not only reduce the storage pressure of the SCADA system, but also save transmission traffic.

[0042] In one method, the SCADA data stored in the SCADA system needs to include at least the data source information (e.g., Beijing or Shanghai) and data producer information (e.g., oil and gas pipeline network equipment A or oil and gas pipeline network equipment B, etc.) of each business node, so that subsequent users can find the business nodes they are interested in according to the source and producer information of each business node in the first display screen.

[0043] Step 2: Based on the corresponding data source information and data producer information in each SCADA data, a first display screen is generated for the user.

[0044] In one embodiment, the display screen of the present application (i.e., including the first display screen, the second display screen, the third display screen, etc.) may include one or more sub-screens. It is understandable that each sub-screen may display SCADA data of one or more service nodes to the user.

[0045] Step 3: Obtain the browsing frequency of each service node by the user in the first display screen.

[0046] It is understandable that, for example, when a user is interested in a business node in the Beijing area, he or she will browse and click on the business node whose data source is Beijing in the first display screen.

[0047] As an example, the browsing frequency may be the number of times a user clicks on a certain service node within a unit time, wherein the unit time may be, for example, 30 seconds or 60 seconds.

[0048] Step 4: The service node with a browsing frequency higher than a preset frequency value is taken as the target service node.

[0049] In one approach, the preset frequency value may be 2 times / minute, that is, when the user clicks on a target service node at least 2 times within 1 minute, the service node is the target service node of interest to the user.

[0050] Step 5: Send a transmission notification to the target business node for acquiring the stored SCADA data stored in the target business node.

[0051] Furthermore, since the storage node of the SCADA system in the embodiment of the present application no longer stores all the SCADA data of each service node (only a small amount of SCADA data of each service node is stored), therefore, in order to show the user a second display screen containing more comprehensive data, the embodiment of the present application needs to send a transmission notification from the SCADA system to the target service node, so as to synchronize the stored SCADA data stored by the target service node itself to the SCADA system.

[0052] In other words, after the service node in this application collects the SCADA data of the industrial equipment associated with itself, it no longer transmits all of it to the SCADA system, but stores most of the SCADA data in its own storage node. And only when the subsequent SCADA system needs it (i.e., when receiving a transmission notification), will it transmit the SCADA data to the SCADA system.

[0053] Step 6: After acquiring the stored SCADA data from the target service node, a second display screen is generated for the user based on the stored SCADA data.

[0054] It can be understood that after the SCADA system receives the stored SCADA data at the target service node, it can display a second display screen containing more comprehensive data to the user based on the data.

[0055] In one embodiment, the second display screen may be generated based on the first display screen, or may be a completely new display screen, which is not limited in the present application.

[0056] Step 7: Obtain the browsing time of the user in the second display screen for the stored SCADA data. If it is detected that the browsing time is longer than the preset time, send a collection notification to the target business node.

[0057] The collection notification is used to inform the target service node to collect SCADA data in real time and transmit the collected real-time SCADA data to the cache node.

[0058] In one method, the preset duration may be 1 minute or 5 minutes, etc.

[0059] For example, when the user browses the stored SCADA data of the target business node in the second display screen for more than 5 minutes (that is, the user stays in the sub-interface displaying the stored SCADA data for a long time), it means that the target business node is a business node that the user is very interested in.

[0060] Step 8: Receive real-time SCADA data, and generate a third display screen for the user based on the real-time SCADA data.

[0061] In one embodiment, the real-time SCADA data may be SCADA data of all industrial equipment associated with the target business node and collected by the target business node.

[0062] In another way, in order to avoid the problem of consuming storage space and transmission resources of storage nodes caused by transmitting unnecessary SCADA data, real-time SCADA data can also be collected by the target business node, which is the SCADA data of some industrial equipment (i.e., target industrial equipment) that the user is interested in.

[0063] As an example, the target industrial device may be determined based on the browsing time and / or browsing frequency of each industrial device in the second display screen by the user.

[0064] Furthermore, in order to show the user more and more comprehensive display screens about the target service node in the embodiment of the present application, the embodiment of the present application needs to instruct the target service node to immediately start the step of collecting SCADA data (that is, regardless of whether the current target service node is within the collection period) through a collection instruction. And subsequently, based on the latest collected SCADA data, a third display screen is generated for the user.

[0065] Step 9: When a display stop instruction is received, the stored SCADA data is cleared, and an association relationship between the real-time SCADA data and the target business node is established.

[0066] It is understandable that, since the target business node is a business node of interest to the user, in order to facilitate the subsequent display of the SCADA data of the business node to the user, the embodiment of the present application can retain its SCADA data.

[0067] In one way, in order to reduce the storage pressure of the storage node in the SCADA system as much as possible, the embodiment of the present application chooses to retain the latest collected data (i.e., real-time SCADA data) of the target business node and clear the expired data (i.e., stored SCADA data). This can achieve the purpose of displaying the relevant business data of the target business node to the user and can also reduce the data storage pressure of the storage node.

[0068] Step 10: Store the association relationship in the cache node.

[0069] By applying the technical solution of the present application, after detecting that each business node of the SCADA system has collected SCADA data, it is not necessary to transfer all of it to the storage node of the SCADA system immediately. Instead, in the subsequent process of displaying data to the user, after detecting that the user is interested in the SCADA data of a certain business node, the data stored in the business node is called to display it to the user. And when it is confirmed again that the user has a display demand, the data collection function of the business node is immediately started, so as to realize the display of the latest SCADA data generated by the current business node to the user.

[0070] On the one hand, this avoids the problem of consuming a large amount of transmission resources and excessive storage pressure on the storage node caused by each business node transmitting a large amount of SCADA data to the storage node of the SCADA system. On the other hand, the steps of acquiring SCADA data in segments and displaying the screen in segments can also reduce the screen generation pressure of the SCADA system and reduce the disadvantage of consuming operating resources caused by showing users pictures that they are not interested in.

[0071] Optionally, in another embodiment of the method of the present application, generating a first display screen for the user includes: Obtain the corresponding data source information and data producer information in the SCADA data of each business node; Based on the corresponding data source information and data producer information in each SCADA data, the first display screen is generated for the user.

[0072] Optionally, in another embodiment of the method of the present application, selecting at least one target service node of interest to the user from each service node includes: Obtaining the browsing frequency of each service node by the user in the first display screen; The service node whose browsing frequency is higher than the preset frequency value is used as the target service node.

[0073] Optionally, in another embodiment of the above method of the present application, after generating a second display screen for the user based on the stored SCADA data, the method further includes: Obtaining a browsing time of the user on the second display screen for the stored SCADA data; If it is detected that the browsing duration is greater than the preset duration, the collection notification is sent to the target service node.

[0074] Optionally, in another embodiment of the method of the present application, the sending a collection notification to the target service node includes: Acquire all industrial devices associated with the target service node; Selecting at least one target industrial device that the user is interested in from various industrial devices; Sending to the target service node, collecting SCADA data of the target industrial equipment in real time, and transmitting the collected real-time SCADA data to the cache node.

[0075] Optionally, in another embodiment of the method of the present application, after generating the third display screen for the user, the method further includes: When receiving a display stop instruction, clearing the stored SCADA data, and establishing an association relationship between the real-time SCADA data and the target service node; The association relationship is stored in the cache node.

[0076] Optionally, in another embodiment of the present application, Figure 3 As shown, the present application also provides a SCADA data display system for oil and gas pipeline network. It includes: The receiving module 201 is configured to generate a first display screen for the user based on the SCADA data from each business node stored in its own cache node when receiving the display instruction; A selection module 202 is configured to select at least one target business node of interest to the user from each business node, and send a transmission notification to the target business node, wherein the transmission notification is used to obtain the stored SCADA data stored in the target business node; The sending module 203 is configured to generate a second display screen for the user based on the stored SCADA data after acquiring the stored SCADA data from the target business node; and send a collection notification to the target business node, wherein the collection notification is used to inform the target business node to collect SCADA data in real time and transmit the collected real-time SCADA data to the cache node; The generating module 204 is configured to generate a third display screen for the user based on the real-time SCADA data.

[0077] By applying the technical solution of the present application, after detecting that each business node of the SCADA system has collected SCADA data, it is not necessary to transfer all of it to the storage node of the SCADA system immediately. Instead, in the subsequent process of displaying data to the user, after detecting that the user is interested in the SCADA data of a certain business node, the data stored in the business node is called to display it to the user. And when it is confirmed again that the user has a display demand, the data collection function of the business node is immediately started, so as to realize the display of the latest SCADA data generated by the current business node to the user.
