Technical Field
[0001] This application relates to the field of communication technology, and more specifically, to a method, apparatus, and electronic device for managing remote terminal units in substations. Background Technology
[0002] In current power automation systems, the operational status monitoring of Remote Terminal Units (RTUs) typically relies on the Supervisory Control and Data Acquisition (SCADA) system within the substation where they are located, creating information silos. Due to differences in data protocols and formats on the northbound interfaces of SCADA systems from different equipment manufacturers, unified monitoring across vendors and sites is impossible. If the central management platform communicates directly with the RTUs in each substation, it would expose network ports to hundreds or even thousands of field terminal devices, leading to extreme complexity in communication network links, operational difficulties, and serious information security risks.

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0022] It should be noted that the terms "first," "second," etc., used in this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or device that includes a series of steps or modules is not necessarily limited to those steps or modules explicitly listed, but may include other steps or modules not explicitly listed or inherent to such processes, methods, products, or devices.
[0023] Figure 1 This is one of the flowcharts illustrating the method for managing a substation remote terminal unit provided in an embodiment of this application, such as... Figure 1 As shown, the method includes steps 110 and 120. These method steps are merely one possible implementation of this application.
[0024] Step 110: Convert the original monitoring data of the remote terminal unit into a preset data format to obtain the monitoring data. The preset data format is constructed based on a hierarchical data model, which defines the data attributes and semantic descriptions of various types of original monitoring data.
[0025] Specifically, the method for managing substation remote terminal units provided in this application is applicable to the SCADA system of a substation.
[0026] The method for managing substation remote terminal units provided in this application is executed by a device for managing substation remote terminal units. This device can be a hardware device independently set up in the SCADA system, or it can be a software program running in the SCADA system.
[0027] A substation is a physical location that contains a large number of electrical equipment, such as transformers and circuit breakers.
[0028] An RTU is a physical device installed within a substation. It is directly connected to the electrical equipment in the substation, collects their real-time status data such as voltage, current, and switch positions, and can execute commands issued from higher-level units, such as remote closing / opening. A substation can have multiple RTUs.
[0029] SCADA systems are software systems deployed within substations, typically running on dedicated servers or industrial control computers. SCADA systems manage all RTUs and other intelligent devices within the substation. They collect data from the RTUs to create a unified view of the substation, allowing maintenance personnel to monitor and execute local automation control strategies.
[0030] Raw monitoring data consists of various types of monitoring information generated by the RTU that have not undergone standardized processing. This data may include RTU-related data, remote control-related information, and real-time operating and communication status data of the RTU and the monitored equipment. A preset data format is a standardized data structure predefined to achieve unified management of data across vendors and protocols.
[0031] The Unified Data Description Language (UDDL) can be used as a default data format to model and unify the semantics of raw monitoring data from different vendors and protocols, thus resolving the issue of inconsistent interfaces. This UDDL is built upon a hierarchical data model.
[0032] A hierarchical data model is a data modeling method that organizes complex data in a structured manner according to logical layers, such as basic information, real-time status, and events. The hierarchical data model solves compatibility issues between different vendor systems by uniformly defining the data attributes and semantic descriptions of various types of raw monitoring data. Data attributes refer to labels or fields that describe the characteristics of data. Semantic descriptions refer to the explicit interpretation of the meaning of data, ensuring that different systems have the same understanding of the same attribute.
[0033] Unlike traditional JSON / XML formats, UDDL adds mandatory attribute tags and semantic identifiers to the data structure. By adding attribute tags and semantic identifiers on top of JSON / XML, it ensures that all access systems follow a unified semantic specification, thereby uniformly converting raw monitoring data from RTUs of different protocols and vendors into standardized monitoring data and achieving cross-vendor semantic uniformity.
[0034] This application embodiment establishes a unified hierarchical data model and configures a preset data format, enabling the SCADA system within the substation to transmit the monitoring and management indicators of the RTU, i.e., the monitoring data, to the upper-level central management platform in accordance with this standard, thereby achieving centralized management of RTU monitoring data from multiple substations.
[0035] Step 120: Send the monitoring data to the central management platform so that the central management platform can manage the remote terminal unit based on the monitoring data.
[0036] Specifically, the central management platform is a centralized upper-level application system used to collect, process, and display RTU monitoring data from multiple substations, enabling unified monitoring of RTUs across regions and substations.
[0037] The SCADA system sends standardized monitoring data to a central management platform. This platform can store, analyze, and visualize this monitoring data, and perform advanced management functions such as health status assessment, fault diagnosis, and root cause analysis.
[0038] The central management platform is isolated from the RTU and interacts only through the northbound interface of the SCADA system, which improves the security of data transmission.
[0039] The method for managing substation remote terminal units provided in this application converts various types of raw monitoring data into a unified, semantically clear, standardized format and uploads it to the central management platform. This fundamentally solves the problem of information silos caused by different equipment manufacturers' interface protocols and data formats, and avoids the difficulty of complex adaptation for upper-level platforms to be compatible with multiple manufacturers' equipment. It can realize centralized and standardized management of remote terminal units across manufacturers and sites. By isolating the direct interaction between the central management platform and the RTU through the SCADA system, the overall security of data transmission is effectively improved.
[0040] It should be noted that each implementation method of this application can be freely combined, rearranged, or executed individually, and does not need to rely on or depend on a fixed execution order.
[0041] In some embodiments, a protocol adapter is deployed on the northbound interface of the data acquisition and monitoring control system, and step 110 includes: The communication protocol type of the remote terminal unit is determined based on the protocol adapter; The data format of the original monitoring data is converted based on the communication protocol type and preset data format.
[0042] The various types of raw monitoring data include static data of remote terminal units, real-time operation data, and diagnostic alarm data; the hierarchical data model includes a basic layer, an operation layer, and an event layer. The hierarchical data model defines labels for the data attributes of static device data as basic layer data, labels for the data attributes of real-time operational data as operational layer data, and labels for the data attributes of diagnostic alarm data as event layer data.
[0043] Specifically, the northbound interface refers to the interface used by the SCADA system to transmit data to upper-layer systems, such as the central management platform. A protocol adapter is a software module or agent program capable of parsing multiple communication protocols and converting data formats. The data format conversion task is performed by the protocol adapter deployed on the SCADA system's northbound interface.
[0044] The protocol adapter can automatically identify the underlying communication protocol type used by the RTU, such as IEC104, DNP3, Modbus, or proprietary protocols of specific vendors. The protocol adapter also has a self-learning mechanism that can automatically generate or optimize field mapping templates for different protocols during use, improving adaptation efficiency and accuracy, and enhancing cross-system compatibility.
[0045] After determining the communication protocol type, the protocol adapter converts the collected raw monitoring data into a UDDL structure, which is a preset data format. Its data structure is defined by a hierarchical data model.
[0046] The layered data model is a three-layer data model that logically divides raw monitoring information into three layers, which are then uniformly encapsulated and semantically described by UDDL. These three layers are: The base layer, which carries static device data. Static device data refers to metadata describing the physical attributes and configuration of the RTU itself, such as device model, communication address, and manufacturer information. The protocol adapter maps this type of information from the raw monitoring data to the base layer of the UDDL structure. The runtime layer, which carries real-time runtime data. Real-time runtime data refers to dynamic data reflecting the current operating status of the RTU, such as telemetry values, remote signaling status, and remote control command feedback. The protocol adapter maps this frequently changing real-time data to the runtime layer of the UDDL structure. The event layer, which carries diagnostic alarm data. Diagnostic alarm data refers to event information recording RTU anomalies, faults, or important operations, such as communication interruption alarms and Sequence of Events (SOE) records. The protocol adapter maps this event information to the event layer of the UDDL structure.
[0047] The protocol adapter uses this three-layer data model as a standard template to accurately map raw monitoring data from different protocols to the corresponding layers of fields in the UDDL structure, and attaches a unified semantic identifier. This process ensures that regardless of the original monitoring data format, the converted UDDL data has a unified and unambiguous structure and meaning.
[0048] After completing the conversion to the UDDL structure, the protocol adapter packages the standardized monitoring data into messages and uploads them to the central management platform via the SCADA northbound interface. The central management platform's southbound interface receives the standardized monitoring data conforming to the UDDL protocol.
[0049] The method for managing substation remote terminal units provided in this application solves the problem of incompatibility between interfaces of SCADA systems from different manufacturers by deploying a protocol adapter on the northbound interface of the SCADA system and using a structured three-layer data model to guide the generation of UDDL, thereby achieving standardization and semantic unification of monitoring data.
[0050] In some embodiments, the data acquisition and monitoring control system and the central management platform include multiple transmission channels, including a message queue telemetry transmission channel and a Hypertext Transfer Security Protocol (HTTP) channel. Step 120 includes: Determine the transmission type of the monitoring data; the transmission type includes a first transmission type and a second transmission type; the transmission time requirement of the first transmission type of monitoring data is greater than the transmission time requirement of the second transmission type of monitoring data. When the transmission type is the first transmission type, the monitoring data is sent to the central management platform based on the message queue telemetry transmission channel; When the transmission type is the second transmission type, the monitoring data is sent to the central management platform based on the Hypertext Transfer Protocol Security (HTTP) channel.
[0051] Step 120 also includes: Monitoring data is sent to the central management platform based on transport layer security protocols.
[0052] Generate a data summary of the monitoring data; The blockchain-based auxiliary verification channel sends data summaries to the central management platform, enabling the platform to verify the integrity and source credibility of the monitoring data.
[0053] Specifically, the SCADA system and the central management platform employ a hybrid protocol (UDDL-over-MQTT / HTTPS) dual-channel transmission mechanism for UDDL data transmission, based on either Message Queuing Telemetry Transport (MQTT) or HyperText Transfer Protocol Secure (HTTPS). This mechanism involves a hybrid protocol strategy, with multiple transmission channels built into the SCADA system and the central management platform, including a lightweight / real-time MQTT channel and a reliable / batch HTTPS channel. A message classification scheduler automatically selects the optimal channel based on the timeliness requirements of the monitoring data transmission, achieving a hybrid transmission mode of real-time fast channel + stable guarantee channel. The transmission timeliness requirement refers to the maximum allowable delay time from data generation to reception.
[0054] For monitoring data of the first transmission type with high timeliness requirements, such as remote signaling and alarm monitoring data, the MQTT channel is selected for push.
[0055] For monitoring data of the second transmission type with lower timeliness requirements, such as large volumes of non-real-time monitoring data like telemetry curves, configuration files, and firmware updates, the HTTPS channel is selected for transmission. Simultaneously, the HTTPS channel also serves as a backup channel in case of MQTT channel interruption, ensuring uninterrupted data transmission. If the MQTT channel is interrupted, it automatically switches to the HTTPS channel for transmission.
[0056] The embodiments of this application employ a dual-channel data protection mechanism during data transmission to ensure secure and reliable data transmission.
[0057] The main business channel is a UDDL-over-MQTT / HTTPS business data channel based on the Transport Layer Security (TLS) protocol.
[0058] The dual-channel data protection mechanism includes transmitting all monitoring data—whether via HTTPS or MQTT—through a TLS-based encrypted channel, such as TLS 1.3, ensuring confidentiality during transmission. Simultaneously, a data digest, such as a hash value, is generated for each monitoring data transmission. This data digest is a unique, fixed-length string calculated from the data block using a hash algorithm, used to verify data integrity. This data digest is then sent to the central management platform via a separate, blockchain-based signature chain-based auxiliary verification channel.
[0059] After receiving monitoring data from the main business channel, the central management platform compares its data summary with the data summary received from the auxiliary verification channel. If they match, the data source is confirmed to be trustworthy and untampered; if they do not match, the data is rejected.
[0060] The method for managing substation remote terminal units provided in this application avoids the security risks associated with direct connection between the central management platform and the RTU by adopting UDDL, dynamic protocol adaptation, and dual-channel trusted transmission. It also ensures compatibility and data reliability across multiple vendors' SCADA systems, offering advantages such as high security, strong compatibility, good scalability, and high operation and maintenance efficiency. It enables centralized monitoring of RTUs across regions and substations, and improves operation and maintenance efficiency through health indices and root cause analysis. By isolating direct interaction between the RTU and the platform, combined with dual-channel trusted transmission and blockchain verification, it ensures the security and reliability of monitoring data.
[0061] The above embodiments are methods for managing substation remote terminal units in a data acquisition and monitoring control system for substations. The following describes a method for managing substation remote terminal units in a central management platform provided by the embodiments of this application. The method for managing substation remote terminal units in a central management platform described below can be referred to in correspondence with the method for managing substation remote terminal units in a data acquisition and monitoring control system for substations described above.
[0062] Figure 2 This is a second flowchart illustrating the method for managing a substation remote terminal unit provided in an embodiment of this application. Figure 2 As shown, the method includes steps 210 and 220.
[0063] Step 210: Receive monitoring data from the remote terminal unit; Step 220: Manage the remote terminal unit based on monitoring data; The monitoring data is obtained by converting the original monitoring data of the remote terminal unit into a preset data format. The preset data format is constructed based on a hierarchical data model, which defines the data attributes and semantic descriptions of various types of original monitoring data.
[0064] Specifically, the method for managing substation remote terminal units provided in this application is applicable to a central management platform. The central management platform receives monitoring data sent by the remote terminal units, stores, analyzes, and visualizes this monitoring data, and performs advanced management functions such as health status assessment, fault diagnosis, and root cause analysis.
[0065] The central management platform adopts a microservice architecture and plug-in adaptation, supports large-scale, multi-vendor SCADA system access, has good scalability, supports horizontal expansion, and can connect to hundreds of substations.
[0066] It should be noted that the method for managing substation remote terminal units applied to a central management platform provided in this application embodiment can correspond to the method for managing substation remote terminal units applied to a data acquisition and monitoring control system for substations described above, and can achieve the same technical effect. Therefore, the parts and beneficial effects that are the same as those in the above embodiments will not be described in detail here.
[0067] The method for managing substation remote terminal units provided in this application converts various types of raw monitoring data into a unified, semantically clear, standardized format and uploads it to the central management platform. This fundamentally solves the problem of information silos caused by different equipment manufacturers' interface protocols and data formats, and avoids the difficulty of complex adaptation for upper-level platforms to be compatible with multiple manufacturers' equipment. It can realize centralized and standardized management of remote terminal units across manufacturers and sites. By isolating the direct interaction between the central management platform and the RTU through the SCADA system, the overall security of data transmission is effectively improved.
[0068] In some embodiments, step 220 includes: The health index of the remote terminal unit is determined based on at least one of the communication delay, heartbeat loss rate and alarm level of the remote terminal unit in the monitoring data. The remote terminal unit is managed based on the health index.
[0069] Specifically, the central management platform adopts a distributed microservice architecture, with the health calculation service responsible for performing this task. The central management platform stores received monitoring data in a time-series database. The health calculation service extracts key performance indicators from the monitoring data stored in the time-series database, including but not limited to communication latency, heartbeat loss rate, packet error rate, and alarm level, and calculates the health index (HI) according to a preset health calculation formula. The health index is a quantitative, comprehensive evaluation indicator used to intuitively reflect the current operational health status of the RTU.
[0070] For example, the formula for calculating HI is as follows: HI = w1 × (1 - communication delay / delay threshold) + w2 × (1 - heartbeat loss rate) + w3 × (1 - packet error rate) - w4 × alarm level.
[0071] Among them, w1, w2, w3 and w4 are the weight coefficients of each indicator, which can be flexibly set according to the user's actual operation and maintenance needs.
[0072] The remote terminal unit is managed based on the calculated health index.
[0073] The central management platform displays the health index of all RTUs across the entire network through a visual interface, enabling maintenance personnel to intuitively and quickly grasp the overall operating status of the equipment.
[0074] The health index calculation mechanism enables the platform to proactively diagnose potential problems. For example, when the health index of any RTU falls below a preset threshold, the central management platform can automatically trigger an alarm and notify maintenance personnel through methods such as interface highlighting and message push, achieving precise alarm location.
[0075] After an alarm is triggered, the central management platform can further call the root cause analysis service to comprehensively judge the cross-site abnormal data of the RTU and its associated devices, assisting maintenance personnel in quickly locating the root cause of the fault.
[0076] The method for managing substation remote terminal units provided in this application transforms traditional passive response-based operation and maintenance into proactive diagnostic intelligent operation and maintenance, thereby solving the problem of difficulty in achieving centralized assessment and intelligent diagnosis of the status of all network equipment in the context of data incompatibility between cross-vendor SCADA systems, and significantly improving operation and maintenance efficiency.
