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

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

[0036] Communication management module, the communication management module is used to manage multiple independently running functional modules of the communication system, the communication management module is in communication connection with multiple functional modules, the functional modules include 101 / 104 master station forwarding module, upward forwarding module and downward collection module, the distribution terminal exchanges data with the distribution master station through the 101 / 104 master station forwarding module, and the distribution terminal exchanges data with the communication equipment through the upward forwarding module and the downward collection module;

[0037] SQL database, which includes system operation management configuration information and configuration files of functional modules. The SQL database is connected with multiple functional modules through a central data bus;

[0038] Configuration maintenance tool, the configuration maintenance tool is connected with the communication management module and configures the functional modules of the communication system through the communication management module, the configuration maintenance tool is connected with the SQL database communication, the communication system obtains the system operation management configuration information and configuration files through the configuration maintenance tool to realize the addition of functional modules.

[0039] It should be noted that the communication system is a component of the distribution terminal. The communication system runs on the Linux system. The distribution terminal completes the data interaction between the distribution terminal and the distribution master station, the distribution terminal and the communication equipment through the communication system. The communication system adopts a data input / data output control system architecture. Multiple functional modules share a central data bus. The central data bus includes a real-time library / command queue / event queue, etc. Multiple functional modules work on the central data bus and realize data interaction and data synchronization between data through the central data bus.

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

[0041] It should be noted that the functional modules include M4Core protection core communication module, 101 / 104 master station acquisition module, 101 / 104 master station forwarding module, historical data storage module, satellite GPS communication module, panel indicator communication module, LCD display module, management machine module, etc. Among them, the communication equipment includes the upper forwarding equipment and the lower acquisition equipment. The distribution terminal exchanges data with the communication equipment through the upper forwarding module and the lower acquisition module of the functional module; and exchanges data with the distribution master station system through the 101 / 104 master station forwarding module of the functional module, so as to realize the data exchange between the distribution terminal and the distribution master station. The 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 be run by the current distribution terminal. The communication system realizes the configurable operation of each APP of the communication module through the system operation management configuration information. A functional module has a unique configuration file. The configuration file corresponding to the functional module is downloaded from the SQL database to the distribution terminal through the configuration maintenance tool, which can realize the normal operation of the functional module corresponding to the configuration file.

[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, through the distribution terminal communication system based on configuration modularization provided in this embodiment, the communication system of the distribution terminal can configure the functional modules in a configuration modularization manner, select the functional modules required by the communication device based on the communication device connected to the distribution terminal, and download the system operation management configuration information and the configuration file of the selected functional module to the distribution terminal through the configuration maintenance tool, that is, through the configuration maintenance tool, the system operation management configuration information and the configuration file, the addition of a single functional module is realized. Correspondingly, according to the actual needs of operation, the functional module can be deleted and the function modified in the communication system through the configuration maintenance tool, the system operation management configuration information and the configuration file, without affecting the normal operation of other functional modules. Data sharing of each functional module of the communication system is realized through the central data bus, and each functional module operates independently; the communication management module monitors the operation status of the functional module. When a stubborn error occurs in a functional module, the communication management module can be used to suspend the operation of the functional module without affecting the normal operation of other functional modules, thereby ensuring that the communication system is in working condition.

[0045] In addition, in one embodiment, the power distribution master station includes a data acquisition and monitoring control system, and the protocol parameters of the power distribution terminal are configured by configuring a 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 distribution terminal has information interaction with the data acquisition and monitoring control system. The communication system belongs to the communication monitoring end. There are two main communication protocols: 101 serial communication protocol and 104 network protocol. The communication system configures the communication parameters in the 101 protocol and 104 protocol through the configuration maintenance tool, and saves them in the scada_tab le data table in the SQL database. The configuration maintenance tool is used to configure the protocol parameters of the distribution terminal, complete the communication monitoring, and complete the forwarding to the distribution master station.

[0047] In addition, in one 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 distribution terminal for the virtual communication devices, the forwarding set is used to generate a forwarding table, and the monitoring set is used to bind the ports of the distribution master station and the distribution terminal, and to associate the monitoring objects and forwarding tables of the data acquisition and monitoring control system.

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

[0049] In addition, in one 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, the system operation management configuration information and the configuration file corresponding to the functional module.

[0050] It should be noted that SQL obtains the paired virtual communication devices and device IDs generated by the configuration maintenance tool, where the device ID is unique; devid is generated based on the device ID, and the forwarding table includes devid. At the end of the overall configuration of the communication system, a continuous and unique overall ID is generated based on the external devices of the communication system. A functional module corresponds to a configuration file. The distribution terminal downloads a configuration file and system operation management configuration information through the configuration maintenance tool. The distribution terminal can only run the functional module corresponding to the configuration file. The system operation management configuration information and the configuration files corresponding to the functional modules are stored in the configuration library of the SQL database.

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

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

[0053] In addition, in one embodiment, the functional module is communicatively connected to the physical communication device, and the configuration maintenance tool assigns the device ID and original point table of the virtual communication device to the physical communication device. The physical communication device includes a device point table, and the device point table of the physical communication device 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 equipment needs to work normally through corresponding functional modules. One functional module can correspond to multiple communication devices. Communication devices that call the same functional module must first be assigned the same original point table. The parameters in the original point table are configured based on actual implementation requirements through the configuration maintenance tool to obtain the device point table.

[0055] In addition, the embodiment of the present invention provides a distribution terminal communication method based on configuration modularization, which is applied to Figure 1 The distribution terminal communication system based on configuration modularization of the embodiment shown in FIG. Figure 2 The method includes but is not limited to the following steps:

[0056] S110, the configuration maintenance tool generates a communication device template library based on the preset communication protocol and the externally imported original template, generates pairs of virtual communication devices and device IDs, and devid based on the communication device template library, and performs port binding between the power distribution terminal and the virtual communication device;

[0057] S120, configuring the maintenance tool to generate a forwarding table based on the demand table sent by the power distribution master station, and associating 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 file and system operation management configuration information corresponding to the functional module required by the physical communication device to the power distribution terminal through the configuration maintenance tool, and the functional module with the downloaded configuration file operates normally;

[0059] S140, the distribution terminal exchanges data with the distribution master station through the 101 / 104 master station forwarding module, the distribution terminal exchanges data with the communication equipment through the upward forwarding module and the downward acquisition module, the communication management module monitors the functional module, and the communication management module stops the function module that is working abnormally.

[0060] It should be noted that the configuration maintenance tool is based on the self-description of the communication protocol. According to the functional division of the functional module, a corresponding data model is established for the data input and output realized by the functional module. According to the data model, a database table is generated through the SQL database. The database table includes a telesignal table, a telemetering table, a remote control table, etc. Generating a database table is to generate a communication protocol library. Each functional module has different communication protocols. After completing the generation of the communication protocols of all functional modules, proceed to the next step.

[0061] Exemplarily, a protection core communication protocol library is established based on the M4Core protection communication module and protection core communication, which involves the establishment of tables such as basic configuration table, telesignaling table, telemetering table and remote control table. After the basic configuration table, telesignaling table, telemetering table and remote control table are written into the SQL database, the equipment table, telesignaling table, telemetering table, telepulse table, remote control table and constant value table will be established.

[0062] Exemplarily, based on the 101 / 104 master station acquisition module and the 101 / 104 acquisition protocol, a distribution acquisition master station 101 / 104 protocol library is established, and a library is built for collecting four remote information from distribution terminals. After the four remote information collected by the distribution terminals is written into the SQL database, the TABLE structures such as telemetry ai, teleregulation ao, telepulse ci, basic configuration device, telesignal di, remote control do and set value setting can be queried in the library, and the structure definition of the telemetry table and the telemetry table can be seen.

[0063] It should be noted that, based on the generated communication protocol library, a set of universal standards for communication equipment suitable for the protocol is established, namely, the communication equipment template library. For the same type of equipment, the function of reusing the original point numbers of the four remote controls is achieved. A template_tab le table is created in the SQL database, and all templates created according to the communication protocol are inserted into the original template in the table. After the original template is inserted, the communication equipment template library is generated. A functional module corresponds to a communication equipment template in a communication equipment template library. After the communication equipment template is established, the telesignaling, telemetry, remote control and set value information associated with the communication equipment template are automatically configured through the configuration maintenance tool, so as to facilitate the subsequent establishment of external communication equipment.

[0064] It should be noted that the original templates include empty template, Beidou / GPS time synchronization template, serial port recording file transfer template, State Grid standard power supply protocol-standard template, State Grid standard power supply protocol-Southern Grid template, dual-core communication protocol template (recording type DTU), gateway machine template (M151 platform), inter-board serial communication template (conventional DTU), State Grid power panel template (DTU), and external battle damage device template (DTU). The content field of the original template saves the detailed four-remote definition of the corresponding protocol template. The original template has been designed before configuring the communication system and imported from the outside through the configuration maintenance tool.

[0065] It should be noted that for the same communication equipment template, there are multiple devices of the same type connected to the distribution terminal. Each device of the same type uses the original point table of the same communication equipment template. During configuration design, a unique device ID is generated for each communication device. At the same time, for the same type of information (such as telemetry) in the corresponding protocol library table, the original inf is the same, and different id sequences are generated, and devid is used to distinguish the devices. The communication equipment is established based on the communication equipment template through the device set of the configuration maintenance tool. The basic information of the communication equipment is modified based on the communication equipment template according to the operation needs. The parameters of the communication equipment are the actual operation parameters, and the template is the basic information and default information agreed upon for the same type of equipment. Among them, the same type of equipment is the communication equipment that calls the same functional module.

[0066] Exemplarily, based on the protection core communication template, a protection communication device is established, and basic information of the protection communication device is related to the actual use of the functional module.

[0067] For example, an external serial port communication device is established. According to the external serial port communication template, the external device is connected through the serial port. The communication template is derived from the four-remote point table forwarded by the external serial port device. The protocol library used by the external serial port 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, refer to Figure 3 , Figure 3 The result of binding the port of the communication device to the configuration maintenance tool provided in this embodiment is as follows: Figure 3 The left side is the communication device bound to the port, and the right side shows the network port or serial port configuration information corresponding to the port. The communication device port binding result is to specify the port of the communication system of the power distribution terminal for the communication device through the port set of the configuration maintenance tool to achieve hardware binding; the communication device includes the downward acquisition device (network port 104, specify the IP and port number; serial port 101, specify the link address and public address, baud rate, data bit, stop bit, parity check) and the upward forwarding device (network port 104, specify the IP and port number; serial port 101, specify the link address and public address, baud rate, data bit, stop bit, parity check). The result of the communication device binding port is written into the port_table in the SQL database through the configuration maintenance tool.

[0069] It should be noted that the configuration maintenance tool extracts the four remote point tables that the communication equipment needs to forward based on the demand table sent by the distribution master station to generate a forwarding table to meet the real-time monitoring requirements of the distribution master station. The forwarding set configuration of the configuration maintenance tool needs to forward the point table to the distribution master station and update it to the forwarding table database. The distribution terminal can have multiple forwarding tables, which are saved in the forward_table table in the SQL database. The specific telesignaling sub-table, telemetry sub-table and remote control sub-table are saved in the forward_d i_table table, forward_ai_table table and forward_do_table table, and the fixed value sub-table is saved in the forward_settling_table table.

[0070] It should be noted that, refer 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 through the 101 protocol, Figure 5 Match the serial communication address and port of the data acquisition and monitoring control system for the distribution terminal communication system implemented through the 104 protocol. Configure the protocol parameters of the data acquisition and monitoring control system on the distribution terminal through the configuration maintenance tool to complete the communication monitoring; the distribution terminal communication system communicates with the data acquisition and monitoring control system, and the distribution terminal communication system is the communication monitoring end. The communication protocols mainly include the 101 serial communication protocol and the 104 network protocol. The communication terminal configures the communication parameters in the 101 protocol and the 104 protocol through the configuration maintenance tool, and saves them in the scada_table data table in the SQL library.

[0071] It should be noted that a continuous ID is generated for all external communication devices of the communication system through the configuration maintenance tool; after all files generated by the configuration maintenance tool are updated to the SQL database through the configuration maintenance tool, the information required for the operation of the functional module is extracted from the corresponding SQL database with the help of the configuration maintenance tool, and the self-description file of the distribution terminal is generated. The system operation management configuration information sysmgt__.xml file is automatically generated according to the port set and historical library set of the configuration maintenance tool. According to the communication equipment in the device set of the configuration maintenance tool, the four remote configuration information files appdbXXX.xml of the functional modules corresponding to each communication device are automatically generated. The sysmgt__.xml file determines which functional modules can be run by the current distribution terminal. According to the functional modules configured by the system operation management information sysmgt__.xml and the corresponding XML configuration files, the configuration software architecture of the distribution terminal is packaged, and after being downloaded to the distribution terminal through the configuration maintenance tool, the actual installation and operation of the distribution terminal is realized.

[0072] It should be noted that after the communication system of the distribution terminal is put into operation, data interaction between the distribution terminal and the distribution master station is realized, and data interaction between the distribution terminal and the communication device is realized. If a new type of external communication device is added during the implementation process, the connection between the external communication device and the distribution terminal is realized through the distribution terminal communication method based on configuration modularization of this application; if an external communication device with an existing communication device template is added, the functional module required by the external communication device is selected, and the configuration file and system operation management configuration information of the selected functional module are downloaded to the distribution terminal through the configuration maintenance tool to realize the normal operation of the functional module. Correspondingly, the functional module can also be deleted or modified through the configuration maintenance tool; the newly added functional module is connected to the central data bus to realize global data sharing, and the communication system does not need to add additional threads through hard coding to add new functional modules; for transient errors of a single functional module, the communication system can be restored and started through a script, and for stubborn errors of a single functional module, the communication management module can be used to suspend the work of the module separately, so that the communication system is in working state.

[0073] In addition, in one 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 four remote information configurations and fixed value information configurations. The device point table facilitates the external connection of the power distribution terminal to the physical communication device.

[0074] It should be noted that the power distribution terminal is connected to multiple external communication devices. In order to distinguish the data of the external communication devices, the communication devices are numbered to distinguish each external communication device. First, the configuration maintenance tool generates virtual communication devices and device IDs, and allocates an original point table to each newly created virtual communication device. Based on the original point table, the four remote information configurations are performed according to the operation requirements to obtain the device point table. The power distribution terminal obtains the demand table sent by the power distribution master station, selects the corresponding device point table of the corresponding device according to the content of the demand table and imports it into the forwarding set, generates a forwarding table, and provides an implementation basis for the subsequent association of the forwarding table with the monitoring object.
