[0002] The gateway machine plays an important role in the integrated automation system of substations. It collects real-time information of the measurement, control, protection and other compartment layer equipment in the substation, sends it to the dispatchers at all levels through protocol conversion, receives the remote control and remote adjustment instructions issued by the dispatchers at all levels and forwards them to the compartment layer equipment in the station. The gateway machine plays the role of an intermediate bridge between the plant and the dispatcher. Therefore, the correctness of the function operation of the gateway machine and the rapid location of abnormalities are crucial to the stability of the substation automation system. With the continuous increase of equipment in the substation system and the increasingly powerful functions, the overall operation reliability of the system needs to be improved. In the routine operation and maintenance of the substation, operation abnormalities often occur, but the abnormalities are difficult to locate. Specifically, in the current substation operation and maintenance, with the increase in the number of substation secondary system equipment and the increasing richness of gateway machine functions, it is difficult to troubleshoot the abnormal functions of the gateway machine system, which takes a long time, and the operation status and task processing status of the gateway machine are more in a "semi-transparent" or "invisible" state. Therefore, it is necessary to propose an abstract process visualization expression method for the core business modeling needs of the gateway machine. Summary of the invention

[0035] Reference to "embodiments" in the present invention means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0036] Embodiment 1

[0037] The present invention provides an abstract process visualization expression method for gateway core business modeling requirements, including:

[0038] The core business functions of the gateway machine are sorted out. Each core business function contains multiple key nodes. The core business functions of the gateway machine include remote control, data forwarding, status quantity collection and electrical quantity collection. Each business function contains multiple key nodes.

[0039] Clarify the key elements contained in each node; based on the characteristics of the core business function processing flow of the gateway machine, use the topological sorting method to establish the dependency relationship between the key node elements of the gateway machine function; thereby further abstracting the node transfer and state switching process of the entire function process, and establishing the corresponding relationship between the key nodes of the gateway machine function and the application system process in the monitoring background. When the business function of the gateway machine is abnormal, the abnormal key node can be directly located and returned to the monitoring background.

[0040] The monitoring background obtains the status information of the business function nodes of the gateway machine through system calls, and expresses the business function process of the gateway machine in the form of state machines, flow charts, etc., intuitively showing the business function processing process of the gateway machine, so that the personnel at the plant and dispatch ends can have a more intuitive grasp of the entire process of the core business of the gateway machine.

[0041] Based on the entire process of gateway machine business processing, the key nodes of each business function are sorted out, such as Figure 1 As shown, the remote control function mainly includes the reception and analysis of remote control commands, protocol and data conversion, remote control command export, etc.; data forwarding mainly includes channel status, data collection, protocol and data conversion, data sending, etc.; local status quantity and quantity measurement collection mainly include the monitoring of the gateway's own key indicators, the monitoring of the IEC61850 communication status with other devices, and the monitoring of the communication status with the main station IEC104, etc.

[0042] like Figure 2 The figure shows the key process and monitoring elements of the gateway machine processing the remote control command of the master station. For control functions, the data gateway machine receives the unified standard instructions issued by the dispatching master station, parses the instructions, determines the control object of the master station according to the forwarding table, performs protocol mapping conversion internally, sends the control command to the measurement and control device, and globally controls the entire operation process to ensure that only one remote control operation is in progress at the substation at the same time. The main functional nodes of the gateway machine remote control business can be abstracted as follows:

[0043] Control command reception: The gateway receives remote control commands issued by the dispatching center through a dedicated data channel, mainly the opening and closing operations of circuit breakers and disconnectors.

[0044] Instruction parsing: The gateway receives the control message from the master station, performs protocol parsing, and determines the control object based on the forwarding table. If the control object sent by the master station does not exist in the forwarding table, an error is returned directly.

[0045] Data mapping: After the instruction parsing in the previous step, the gateway determines the control object and control status of the master station, and determines the corresponding relationship between the device and the secondary device according to the interval to which the primary device belongs.

[0046] Protocol conversion: Determine the measurement and control device and control status associated with the primary equipment, and complete the remote control message packaging in the format of the measurement and control communication protocol inside the gateway.

[0047] Command sending: The gateway sends remote control commands to the corresponding measurement and control device. The command sending process first determines the communication link status. If the communication link is interrupted, the command sending fails.

[0048] Command return: The gateway receives the remote control message and equipment status message returned by the measurement and control device, determines the execution status of the command based on the returned message or other prompt information, and verifies the correctness.

[0049] Protocol conversion: The gateway receives the remote control message returned by the measurement and control device and completes the conversion between the downstream communication protocol and the master station communication protocol.

[0050] Master station data construction: According to the forwarding table, the gateway packages the control object information and control results to form a standard scheduling protocol message.

[0051] Sending control instructions: The gateway returns the remote control results to the dispatching master station via a dedicated data channel in the format of standard communication protocols, completing the control process of the entire remote control operation of the master station.

[0052] Operation records and reports: The control business has a complete operation record and reporting system. All control instructions and related operations are recorded in the gateway machine, including instruction content, execution time, device response, etc. This helps to trace the operation history, analyze problems and evaluate the operation status.

[0053] For the main functional nodes of the above remote control processing, the processing chain from input to output is analyzed in detail. The input is the control command of the remote master station, which is transmitted to the gateway machine in the station through a dedicated data channel. After the gateway machine receives the command, it parses and performs a series of processes such as data mapping and protocol conversion, and then sends the command to the measurement and control device. The measurement and control return operation results are transmitted back to the dispatching master station through a dedicated data channel to complete the processing chain of the remote control function.

[0054] According to the core business function processing flow of the gateway machine, each key node element is abstracted and extracted to build the gateway machine function mechanism logic and key node status model;

[0055] The abstract extraction of each key node element includes:

[0056] The core business function processing flow of the gateway machine is regarded as a one-way dependency. The next node function will be started after the current node ends normally. Otherwise, the process ends and an error is returned.

[0057] Based on this logical relationship, according to the core business function processing flow of the gateway machine, the topological sorting method is used to sort the key functional nodes in sequence, and each node is abstracted as an endpoint in the topological sequence, represented by T0, T1, T2... respectively.

[0058] Building the gateway machine functional mechanism logic and key node status model includes:

[0059] Abstract the node transfer and state switching process of the entire function process, and establish a one-to-one or many-to-many correspondence between the key nodes of the gateway machine function and the application system process in the monitoring background;

[0060] The status of key nodes reflects the running status of the application system process. When the gateway machine functions abnormally, the monitoring background calls the relevant application to query the abnormal node status information, or automatically pushes the abnormal node status information through system settings.

[0061] The plant station calls the system application process to analyze the function mechanism logic and key node model of the gateway machine, obtain the logical structure of the core business function of the gateway machine, and display the processing flow of the core business function of the gateway machine and the operating status of key nodes in a visual form;

[0062] Calling the system application process at the plant end refers to deploying a dedicated application process in the background of the substation monitoring system, parsing the functional mechanism logic of the gateway machine and the key node status model, receiving the processing information of the gateway machine's business function, associating the processing information with the key nodes of the gateway machine's business function, and visually displaying the gateway machine's business function processing flow.
