[0069] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following provides a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0070] Embodiment 1

[0071] Refer to Figure 1-2 , for an embodiment of the present invention, a method for viewing the shutdown screen of a power system data communication network is provided, including:

[0072] S100: Obtain a trigger command, send a query instruction based on the trigger command, query data by calling a service interface according to the query instruction, and display the queried operation data;

[0073] S200: Based on the operation data, set parameters for different service levels;

[0074] S300: Debug the service levels with set parameters according to the operation data, and monitor the abnormal state;

[0075] It should be noted that by obtaining the trigger command and quickly sending the query instruction, the system can quickly respond to the user's needs, obtain and display the operation data in real time, improve the speed and efficiency of data processing. Setting parameters for different service levels based on the operation data enables the system to flexibly adjust according to the actual operation situation, improving the adaptability and user-defined ability of the system. By debugging the service levels with set parameters, the system can ensure the normal operation of various services, discover and fix problems in a timely manner, and improve the reliability of the system.

[0076] In the embodiment of the present application, the above step S100 includes the following sub-steps A1 - A3;

[0077] In A1: For the real-time data in the operation data, if there is no new trigger command within the first threshold, refresh the current interface data according to the set time interval;

[0078] In A2: When no IP filtering is added, display the information of all forwarded measurement points under the channel;

[0079] In A3: When IP filtering is added, display the information of the forwarded measurement points of the specified device under the channel.

[0080] Specifically, the first threshold can be 5 seconds, the time interval is 1 second, and the real-time data is the measurement point data in the forwarding table bound to the current channel.

[0081] Specifically, such asFigure 2 As shown in the figure, after the screen signal is triggered, the request command is passed to the MCU through the serial port COM, and the MCU sensor sends the request to the acquisition control program through the serial port COM. The acquisition control program calls the corresponding business interface according to the identification request identifier to obtain the business data. After the request is received, the data is transmitted to the MCU through the serial port, and finally the data is fed back to the screen through the serial port;

[0082] It should be noted that the main control program ensures that each module has clear responsibilities and works together by reasonably dividing the business scope, thereby building an efficient and stable screen data retrieval system; the serial port screen sends query instructions to the server program through the command trigger mechanism. These instructions include but are not limited to data requests, status queries, etc.; after the server receives the command sent by the serial port screen, it calls the corresponding business interface for data query. These business interfaces are responsible for processing various data requests and returning query results. The server sends the query results back to the serial port screen. After receiving the results, the serial port screen parses and displays them to ensure that users can view the required information in real time. The signal input methods are diverse, and the system is equipped with soft keyboard touch and physical buttons, providing flexible and convenient input options.

[0083] Reference Figures 3-27 This embodiment also provides a power system data communication gateway screen reading system, the primary main interface is as follows Figure 3 The following are shown: operation information module, parameter setting module, debugging module and operation and maintenance module;

[0094] Specifically, in the communication link, the link is bound to the protocol type. For example, the telecontrol link refers to the channel where the IEC104 protocol is located, the PMU link refers to the channel where the GBT26865.2 protocol is located, and the protection information link refers to the channel where the IEC103 protocol is located, as Figure 4 、 Figure 5 、 Figure 6 shown;

[0095] The status of interval layer devices displays the information of secondary equipment IED, which is generated by data modeling after parsing the substation configuration description file SCD file through SCL, as Figure 7 shown;

[0096] Real-time data is the measured point data in the forwarding table bound to the current channel. If there is no new trigger within 5 seconds, the current interface data is refreshed at a set time interval of 1 second; when no IP filtering is added, the information of all forwarding measured points under this channel is displayed by default, as Figure 8 shown; if an IP filtering item is added, the information of the forwarding measured points of the specified device under this channel is displayed, as Figure 9 shown;

[0097] Event records include SOE and telecontrol logs, and it is required to query a specified number of historical records according to the time range. If the time is empty, all historical records under this type are requested by default. As Figure 10 、 Figure 11 shown.

[0098] The time synchronization status is required to display the time quality, leap second flag, and other time synchronization status information of each main board.

[0099] As Figure 12 shown, the alarm status is required to display the status information such as CPU problems and CPU voltage obtained by each main board;

[0100] As Figure 13As shown, the dual-machine status requires showing the operating status of the real-time and service network shutdown machines;

[0101] As Figure 14 shown, the program version requires showing the program version information such as the model number and date of each main board;

[0103] Table 1 Menu Function Table of LCD Interface Operating Information

[0104]

[0105]

[0106] It should be noted that by monitoring the status of the telecontrol link, PMU link, protection information link, and interval layer devices, the system can timely detect and prevent potential communication failures, reduce the risk of accidental interruptions; when problems occur in the communication link, the system can quickly locate the source of the problem, accelerate the fault recovery process, and improve the availability of the system; it realizes the comprehensive and real-time access to the in-station operation information, ensuring the reliability and efficiency of the system.

[0107] In the embodiment of the present application, the parameter setting module includes: the system level and the service communication level;

[0122]

[0123]

[0124] It should be noted that the system layer includes network settings (such as IP address, routing table, MAC address), system password, clock information, etc., to ensure the network connection and security settings of the system; the business communication layer includes channel information to ensure the normal operation of each business communication. Based on the parameter settings, the network connection, security, and normal operation of each business communication of the system are ensured, improving the overall performance and reliability of the system.

[0125] In the embodiment of the present application, the debugging module includes: network test and output test;

[0126] The network test includes: If the selected main board can ping the IP address input by the user, the network connection status is normal;

[0127] The output test includes: According to the command of the system, the corresponding device can respond to the corresponding operation, then the output signal is correct and stable.

[0128] Specifically, as Figure 19 shown, the network test detects the network connection status to ensure unobstructed network communication.

[0136] As Figure 24 、 Figure 25 shown, file backup and restoration includes backing up and restoring according to the selected content, including "database, graphic files, pre-data, configuration parameters, alarm history library data, system programs";

[0137] As Figure 26 shown, the query of the status of inputs and outputs includes querying the status of input and output signals to ensure the working status of the control system.

[0138] As Figure 27 shown, the management of event record storage includes managing the size of audit records. When the limit is exceeded, the log records need to be deleted according to the configuration to ensure the compliance of system auditing.

[0139] For specific information, please refer to Table 3

[0140] Table 3 LCD Interface Debugging and System Expansion Business Menu Function Table

[0141]

[0142]

[0143] It should be noted that through user management, the access rights of different users can be precisely controlled to ensure that only authorized users can access sensitive data and perform critical operations, thereby enhancing the security of the system. The audit log records all system operations, which helps to track user behavior and system changes and meet compliance and audit requirements. Backing up system files can prevent data loss and ensure that data can be quickly restored in case of hardware failure, data corruption or security incidents. Querying the status of incoming and outgoing signals can monitor the working status of the control system in real time, and promptly detect and handle potential control problems.
