[0002] Distribution terminals are intelligent terminals in distribution automation systems, possessing functions such as data acquisition, remote control, fault detection and location, and communication and information sharing. They are suitable for scenarios such as distribution ring network cabinets, switch stations, distributed power supply access points, and user-side substations.

[0003] The existing power distribution terminal communication system adopts a single-process multi-threaded structure. However, the single-process multi-threaded communication system architecture requires hard-coding to add threads to achieve communication with other devices. When it is necessary to add, delete, or modify the function of a single functional module of the communication system, the entire communication system needs to be modified. Moreover, a persistent error in a certain functional module of the communication system can cause the entire communication module to exit abnormally, which brings inconvenience to actual use.

[0033] The modularly configured power distribution terminal communication system according to embodiments of the present invention has at least the following beneficial effects: a communication management module, which manages multiple independently operating functional modules of the communication system. The communication management module is communicatively connected to the multiple functional modules. The functional modules include a 101 / 104 master station forwarding module, an upward forwarding module, and a downward acquisition module. The power distribution terminal interacts with the power distribution master station through the 101 / 104 master station forwarding module and interacts with the communication equipment through the upward forwarding module and the downward acquisition module. An SQL database, which includes system operation management configuration information and configuration files of the functional modules, is connected to the multiple functional modules through a central data bus. A configuration and maintenance tool, which configures the functional modules of the communication system through the communication management module. The configuration and maintenance tool is communicatively connected to the SQL database. The communication system obtains the system operation management configuration information and the configuration files through the configuration and maintenance tool, thereby enabling the addition of functional modules. According to the technical solution of the present invention, the communication system enables the communication system to operate in a modular configuration and multi-process mode through configuration and maintenance tools and a central data bus, realizing the configurable and independent operation of functional modules, and enabling the start and stop of individual functional modules through the communication management module.

[0034] First, refer to Figure 1 , Figure 1 This is a schematic diagram of a power distribution terminal communication system based on modular configuration, provided in an embodiment of the present invention.

[0035] like Figure 1 As shown, the power distribution terminal communication system based on modular configuration provided in this embodiment is characterized by comprising:

[0036] The communication management module manages multiple independently operating functional modules of the communication system. The communication management module communicates with multiple functional modules, including the 101 / 104 master station forwarding module, the upward forwarding module, and the downward acquisition module. The power distribution terminal interacts with the power distribution master station through the 101 / 104 master station forwarding module, and interacts with the communication equipment through the upward forwarding module and the downward acquisition module.

[0037] The SQL database includes system operation management configuration information and configuration files for functional modules. The SQL database is connected to multiple functional modules through a central data bus.

[0038] The configuration and maintenance tool connects to the communication management module and configures the functional modules of the communication system through the communication management module. The configuration and maintenance tool also connects to the SQL database. The communication system obtains system operation management configuration information and configuration files through the configuration and maintenance tool, thereby enabling the addition of functional modules.

[0039] It should be noted that the communication system is a component of the power distribution terminal. The communication system runs on Linux, and the power distribution terminal uses it to exchange data with the power distribution master station, other power distribution terminals, and communication equipment. The communication system adopts a data input / output control system architecture, with multiple functional modules sharing a central data bus. This central data bus includes a real-time library, command queue, and event queue. Multiple functional modules operate on the central data bus and use it to achieve data exchange and synchronization.

[0040] It should be noted that the communication management module and the configuration and maintenance tool have data interaction capabilities, enabling functions such as data exchange, message monitoring, application start-up and shutdown, and online debugging. The communication management module is used to connect with multiple functional modules and can control the start-up and shutdown of a single functional module without affecting the normal operation of other functional modules.

[0041] It should be noted that the functional modules include the M4Core protection core communication module, the 101 / 104 master station acquisition module, the 101 / 104 master station forwarding module, the historical data storage module, the satellite GPS communication module, the panel indicator communication module, the LCD display module, and the management unit module. The communication equipment includes upstream forwarding devices and downstream acquisition devices. The power distribution terminal interacts with the communication equipment through the upstream forwarding and downstream acquisition modules of the functional modules; it also interacts with the power distribution master station system through the 101 / 104 master station forwarding module of the functional modules, thus realizing data interaction between the power distribution terminal and the power distribution master station. The power distribution master station system runs on the Unix platform.

[0042] It should be noted that the system operation management configuration information determines which functional modules can run at the current power distribution terminal. The communication system uses the system operation management configuration information to enable each APP of the communication module to be configured and run. Each functional module has a unique configuration file. By using the configuration and maintenance tool to download the configuration file corresponding to the functional module from the SQL database to the power distribution terminal, the normal operation of the functional module corresponding to the configuration file can be achieved.

[0043] It should be noted that the configuration and maintenance tool runs on the Windows platform and is used to change the communication parameters and protection settings of the communication system.

[0044] It should be noted that the modularly configured power distribution terminal communication system provided in this embodiment allows for the configuration of functional modules within the power distribution terminal's communication system. Based on the communication devices connected to the power distribution terminal, the required functional modules are selected. The system operation management configuration information and the configuration files of the selected functional modules are downloaded to the power distribution terminal using a configuration and maintenance tool. This allows for the addition of individual functional modules through the configuration and maintenance tool, system operation management configuration information, and configuration files. Similarly, functional modules can be deleted or modified within the communication system according to actual operational needs, without affecting the normal operation of other functional modules. Data sharing among the functional modules of the communication system is achieved through a central data bus, and each functional module operates independently. The communication management module monitors the operational status of the functional modules. When a persistent error occurs in a functional module, its operation can be suspended through the communication management module without affecting the normal operation of other functional modules, ensuring the communication system remains operational.

[0045] In another embodiment, the power distribution master station includes a data acquisition and monitoring control system, which configures the protocol parameters of the power distribution terminal through a configuration and maintenance tool, so that the protocol parameters of the power distribution terminal match the protocol parameters of the data acquisition and monitoring control system.

[0046] It should be noted that the communication system of the power distribution terminal interacts with the data acquisition and monitoring control system. The communication system acts as a communication monitoring terminal, and it primarily uses two communication protocols: the 101 serial communication protocol and the 104 network protocol. The communication system uses configuration and maintenance tools to configure the communication parameters for both the 101 and 104 protocols and saves the configuration data to the `scada_table` data table in the SQL database. By using these configuration and maintenance tools, the power distribution terminal's protocol parameters are configured, enabling communication monitoring and forwarding to the power distribution master station.

[0047] In another embodiment, the configuration and maintenance tool includes a device set, a port set, a forwarding set, and a monitoring set. The device set is used to generate pairs of virtual communication devices and device IDs. The port set is used to specify and bind the ports of the power distribution terminal to the virtual communication devices. The forwarding set is used to generate a forwarding table. The monitoring set is used to bind the ports of the power distribution master station and the power distribution terminal, and associate the monitoring objects of the data acquisition and monitoring control system with the forwarding table.

[0048] It should be noted that the device set in the configuration and maintenance tool records the generated virtual communication devices and device IDs, and the power distribution terminal can generate configuration files based on the devices in the device set; the port set records the binding results, and the power distribution terminal can generate system operation and management configuration information based on the port set; the forwarding set generates a forwarding table based on the device point table of the communication devices; and through the monitoring set, the port binding between the power distribution terminal and the power distribution master station is realized, as well as the association between the monitoring objects of the data acquisition and monitoring control system and the forwarding table. The configuration and maintenance tool pre-configures virtual communication devices to facilitate the subsequent connection of external physical communication devices.

[0049] In another embodiment, the SQL database includes the device ID of the virtual communication device, the devid generated based on the device ID, the overall ID, the port binding result between the virtual communication device and the power distribution terminal, system operation management configuration information, and configuration files corresponding to the functional modules.

[0050] It should be noted that the SQL retrieves pairs of virtual communication devices and device IDs generated by the configuration and maintenance tool. The device ID is unique; the `device` is generated based on the device ID, and the forwarding table includes the `device`. The overall ID is generated as a continuous and unique set of IDs based on the devices connected to the communication system at the end of the overall configuration process. Each functional module corresponds to a configuration file. The power distribution terminal downloads a configuration file and system operation management configuration information through the configuration and maintenance tool. The power distribution terminal can only run the functional modules corresponding to that configuration file. The system operation management configuration information and the configuration files corresponding to the functional modules are stored in the configuration repository of the SQL database.

[0051] In another embodiment, the virtual communication device is bound to the port of the power distribution terminal, and the configuration and maintenance tool includes a communication device template library. The communication device template library includes multiple communication device templates, and each communication device template includes an original point table. The original point table included in each communication device template is unique.

[0052] It should be noted that the configuration and maintenance tool generates a communication device template library based on preset communication protocols and original templates, with one communication device template corresponding to one functional module.

[0053] In another embodiment, the functional module is communicatively connected to the physical communication device. The configuration and maintenance tool assigns the virtual communication device's device ID and original point table to the physical communication device. The physical communication device includes a device point table. The device point table of the physical communication device that is communicatively connected to the same functional module is generated based on the same original point table. The four remote information of the device point table is different from the four remote information of the original point table.

[0054] It should be noted that communication devices require corresponding functional modules to function properly. One functional module can correspond to multiple communication devices. Communication devices that call the same functional module are first assigned the same original point table. The parameters in the original point table are configured based on the actual implementation requirements through the configuration and maintenance tool to obtain the device point table.

[0055] In addition, embodiments of the present invention provide a power distribution terminal communication method based on modular configuration, applicable to... Figure 1 The illustrated embodiment of the power distribution terminal communication system based on modular configuration is referred to... Figure 2 The method includes, but is not limited to, the following steps:

[0056] S110, the configuration and maintenance tool generates a communication device template library based on the preset communication protocol and the original template imported from the outside, and generates pairs of virtual communication devices and device IDs, as well as devid, based on the communication device template library, and binds the power distribution terminal to the virtual communication device.

[0057] S120, the configuration maintenance tool generates a forwarding table based on the demand table sent by the power distribution master station, and associates the monitoring objects of the data acquisition and monitoring control system based on the forwarding table;

[0058] S130, the power distribution terminal generates an overall ID based on the connected physical communication device and selects and downloads the configuration files and system operation management configuration information corresponding to the functional modules required by the physical communication device to the power distribution terminal through the configuration and maintenance tool. The functional modules that download the configuration files operate normally.

[0059] S140, the power distribution terminal interacts with the power distribution master station through the 101 / 104 master station forwarding module, and interacts with the communication equipment through the upstream forwarding module and the downstream acquisition module. The communication management module monitors the functional modules and stops the operation of functional modules that are malfunctioning.

[0060] It should be noted that the configuration and maintenance tool is based on the self-describing of communication protocols. According to the functional division of the modules, it establishes corresponding data models for the data inputs and outputs implemented by each module. Based on the data models, it generates database tables using SQL, including remote signaling tables, telemetry tables, and remote control tables. Generating these database tables generates the communication protocol library, and each functional module has a different communication protocol. The next step is only performed after the communication protocols for all functional modules have been generated.

[0061] For example, a protection core communication protocol library is established based on the M4Core protection communication module and protection core communication, which involves the creation of tables such as the basic configuration table, remote signaling table, telemetry table and remote control table. After the basic configuration table, remote signaling table, telemetry table and remote control table are written into the SQL database, the device table, remote signaling table, telemetry table, remote pulse table, remote control table and setting table will be created.

[0062] For example, a 101 / 104 protocol library for the power distribution acquisition master station is established based on the 101 / 104 master station acquisition module and the 101 / 104 acquisition protocol. A library is built for the four remote information collected by the power distribution terminal. After the four remote information collected by the power distribution terminal is written into the SQL database, the database can be used to query TABLE structures such as telemetry (ai), remote adjustment (ao), remote pulse (ci), basic configuration (device), remote signaling (di), remote control (do), and setting. The telemetry table and its structure definition can be seen.

[0063] It should be noted that, based on the generated communication protocol library, a universal standard for communication equipment suitable for this protocol is established, namely, a communication equipment template library. For the same type of equipment, the function of reusing the original point numbers for remote signaling, telemetry, remote control, and remote monitoring is achieved. A `template_table` table is created in the SQL database. All templates created according to the communication protocol have their original templates inserted into this table. After inserting the original templates, the communication equipment template library is generated. One functional module corresponds to one communication equipment template in the communication equipment template library. After establishing the communication equipment templates, the remote signaling, telemetry, remote control, and setting information associated with the communication equipment templates are automatically configured through configuration and maintenance tools, facilitating the subsequent establishment of external communication equipment.

[0064] It should be noted that the original templates include an empty template, a BeiDou / GPS time synchronization template, a serial port waveform recording file transfer template, a State Grid standard power supply protocol template, a State Grid standard power supply protocol template for Southern Power Grid, a dual-core communication protocol template (waveform recording type DTU), a gateway template (M151 platform), an inter-board serial communication template (conventional type DTU), a State Grid power supply panel template (DTU), and an external battle damage device template (DTU). The content field of the original template stores the detailed four-remote definitions of the corresponding protocol template. The original templates were designed before configuring the communication system and were imported from external systems using configuration and maintenance tools.

[0065] It should be noted that for the same communication equipment template, multiple devices of the same type can be connected to the power distribution terminal. Each device of the same type uses the same original point table of the communication equipment template. During configuration design, a unique device ID is generated for each communication device. Simultaneously, for the same type of information (such as telemetry) in the corresponding protocol library table, although the original inf values ​​are the same, different ID sequences are generated, and the .devid is used to distinguish the devices. Communication devices are established based on the communication equipment template through the device set configured by the maintenance tool. The basic information of the communication devices is modified based on the communication equipment template according to operational needs. The parameters of the communication devices are the actual operating parameters, and the template defines the basic and default information of the same type of device. Among these, devices of the same type refer to communication devices that call the same functional module.

[0066] For example, based on the protected nuclear communication template, a protected communication device is established, and the basic information and functional modules of the protected communication device are related to actual use.

[0067] For example, an external serial communication device is established. Based on the external serial communication template, the external device is connected via a serial port. The communication template originates from the four remote point tables forwarded by the external serial device, and the protocol library used by the external serial communication template is the power distribution acquisition master station 101 / 104 protocol library. According to the communication requirements of the power distribution terminal, other downstream acquisition devices can be created based on the communication device template.

[0068] It should be noted that, referring to Figure 3 , Figure 3 This embodiment shows the result of the configuration and maintenance tool binding ports to communication devices. Figure 3 The left side displays the communication devices bound to the ports, while the right side shows the network port or serial port configuration information corresponding to the ports. The port binding results are configured by specifying the communication system port of the power distribution terminal for the communication devices using the port set in the configuration and maintenance tool, achieving hardware binding. The communication devices include downstream acquisition devices (network port 104, specifying IP and port number; serial port 101, specifying link address and common address, baud rate, data bits, stop bits, and parity) and upstream forwarding devices (network port 104, specifying IP and port number; serial port 101, specifying link address and common address, baud rate, data bits, stop bits, and parity). The port binding results for the communication devices are written to the `port_table` in the SQL database using the configuration and maintenance tool.

[0069] It should be noted that the configuration and maintenance tool extracts the four remote point tables that the communication equipment needs to forward based on the demand table sent by the power distribution master station, generating a forwarding table to meet the real-time monitoring requirements of the power distribution master station. The forwarding set configuration of the configuration and maintenance tool needs to forward to the power distribution master station's point tables and update the forwarding table database. The power distribution terminal can have multiple forwarding tables, which are stored in the forward_table in the SQL database. The specific remote signaling sub-table, telemetry sub-table, and remote control sub-table are stored in the forward_di_table, forward_ai_table, and forward_do_table tables, respectively, while the setting sub-table is stored in the forward_settling_table.

[0070] It should be noted that, referring to Figure 4 and Figure 5 , Figure 4 To match the network communication address and port of the data acquisition and monitoring control system for the power distribution terminal communication system implemented via the 101 protocol, Figure 5 To match the serial communication address and port of the data acquisition and monitoring control system with the power distribution terminal communication system implemented via the 104 protocol, the protocol parameters of the power distribution terminal to the data acquisition and monitoring control system are configured using a configuration and maintenance tool to complete communication monitoring. The power distribution terminal communication system communicates with the data acquisition and monitoring control system, acting as the communication listening end. The main communication protocols used are the 101 serial communication protocol and the 104 network protocol. The communication terminal configures the communication parameters in the 101 and 104 protocols using the configuration and maintenance tool and saves them to the `scada_table` data table in the SQL database.

[0071] It should be noted that the configuration and maintenance tool generates continuous IDs for all external communication devices in the communication system. After updating all files generated by the configuration and maintenance tool to the SQL database, the tool extracts the information required for the operation of functional modules from the corresponding SQL database, generates a self-description file for the power distribution terminal, automatically generates the system operation management configuration information file sysmgt__.xml based on the port set and historical database set of the configuration and maintenance tool, and automatically generates the four-remote configuration information file appdbXXX.xml for each communication device's corresponding functional module based on the communication devices in the device set of the configuration and maintenance tool. The sysmgt__.xml file determines which functional modules the current power distribution terminal can run. Based on the functional modules configured in the system operation management information sysmgt__.xml and the corresponding XML configuration files, the power distribution terminal configuration software architecture is encapsulated and downloaded to the power distribution terminal through the configuration and maintenance tool, enabling the power distribution terminal to be installed and run.

[0072] It should be noted that after the communication system of the power distribution terminal is put into operation, it enables data interaction between the power distribution terminal and the power distribution master station, and data interaction between the power distribution terminal and the communication equipment. If a new type of external communication equipment is added during implementation, the connection between the external communication equipment and the power distribution terminal is achieved through the modular configuration power distribution terminal communication method of this application. If an external communication equipment with an existing communication equipment template is added, the required functional module of the external communication equipment is selected, and the configuration file and system operation management configuration information of the selected functional module are downloaded to the power distribution terminal through the configuration and maintenance tool to achieve normal operation of the functional module. Correspondingly, the functional module can also be deleted or modified through the configuration and maintenance tool. The newly added functional module is connected to the central data bus to achieve global data sharing, and the addition of a new functional module to the communication system does not require the addition of extra threads through hard coding. For a momentary error of a single functional module, the communication system can be restarted through a script. For a persistent error of a single functional module, the module can be suspended individually through the communication management module to keep the communication system in working condition.

[0073] In another embodiment, the configuration maintenance tool generates a virtual communication device and a device ID, completes port binding between the virtual communication device and the power distribution terminal, and generates a device point table based on the original point table for configuring remote information and setting information. The device point table facilitates the connection of external physical communication devices to the power distribution terminal.

[0074] It should be noted that the power distribution terminal is connected to multiple external communication devices. To distinguish the data from these external communication devices, each device is numbered. First, a configuration and maintenance tool generates virtual communication devices and device IDs, assigns an initial point table to each newly created virtual communication device, and then configures the device point table based on the initial point table and operational requirements using remote information (remote control, remote monitoring, and remote telemetry). The power distribution terminal obtains the demand table sent by the power distribution master station, selects the corresponding device point table for each device based on the demand table's content, imports it into the forwarding set, and generates a forwarding table. This provides the implementation basis for subsequently associating the forwarding table with monitored objects.
