The communication mode of the power distribution communication network may include GPRS public network communication, wired private network communication (such as optical fiber network, Ethernet, etc.), wireless private network communication (LTE 230, etc.), the embodiment of the present invention takes the wired private network scene as an example introduce. The following is an introduction to the system deployment of the power distribution communication network in conjunction with Figure 2A:

Business terminals are usually deployed in power distribution rooms to monitor various operating parameters of the system, including switch status, power parameters, phase-to-phase faults, ground faults, and parameters during faults, and feed back these operating parameters to the power distribution and consumption communication network. Business master. The business terminal can access the power distribution communication network through the Ethernet switch. The types of business terminals can include DTU (Distribution terminal unit, station terminal), FTU (Feeder Terminal Unit, feeder terminal), TTU (Distribution Transformer Terminal Unit, distribution transformer terminal), fault indicators, etc., in Figure 2A only DTU This is shown as an example, and is not limited in this embodiment of the present invention. Each type of service terminal can support multiple service types, for example, it can support one or more service types such as remote control, remote signaling, telemetry and fault detection.

Wherein, the service type carried by the service terminal can be preset or modified, and the embodiment of the present invention does not limit the specific service carried by it.

Communication equipment is usually deployed in switching stations/ring network cabinets, substations, and data centers to receive, process, and forward data. For example, communication equipment can be switches and routers. The communication device may also be deployed in a power distribution room. Among them, switches are usually deployed in power distribution rooms, switching stations/ring network cabinets, and switches or routers are usually deployed in substations.

The business master station can be deployed in the data center to pass various operating parameters of the power distribution communication network and send commands for adjusting and controlling the power distribution equipment to the business terminal, so as to realize fault location, fault isolation and non-fault Regional rapid restoration of power supply and other functions. The business master station is usually equipped with a power distribution automation system and an emergency command system.

The communication control unit can be deployed in the data center, and is used for exchanging communication management control data with the communication device, so as to allocate communication resources to the communication device. The communication control unit may be a network management system of a power distribution communication network, or an SDN (Software Defined Network, software defined network) controller, etc., which is not limited in this embodiment of the present invention. The communication control unit can also monitor the operating parameters of the communication equipment in the power distribution communication network, such as the connection relationship between the communication equipment and other communication equipment, the interface parameters of the communication equipment, and the like. It should be noted that the service terminal can also be regarded as a communication device.

In addition, in order to solve the problem of mutual blindness between business data and communication data, and achieve the purpose of dynamically allocating communication resources according to the actual needs of the business, ICMT (Information Communications Migrate Teamwork , Information Communication Migration Cooperation) unit, as shown in FIG. 2B is an ICMT architecture diagram of a power distribution communication network provided by an embodiment of the present invention. The ICMT unit includes a Server end and a Client end, and is used for processing the interaction between the power service data flow and the communication management control data flow. For example, the ICMT unit can obtain the requirements of service terminals for communication capabilities (such as the requirements of the services carried by service terminals for communication resources), as well as the network topology information of the power distribution communication network and the communication capabilities of communication devices, such as the bandwidth information of communication devices , end-to-end delay, etc., and then dynamically calculate the allocation of communication resources.

Specifically, the ICMT unit may include TCD (Terminal Configure Data, terminal configuration data), NTD (Network Topology Data, network topology data), CDD (device context data, Context DeviceData), NSD (Network Service Data, network service data) Four modules, Fig. 2C is an ICMT architecture diagram of a power distribution communication network provided by an embodiment of the present invention. The ICMT unit is introduced below in conjunction with Figure 2B:

Among them, TCDClient is deployed on the service terminal; the server and client of the three modules of NTD, CDD, and NSD, and the TCD Server can be deployed in parallel with the business master station, for example, they can be deployed in the same data center as the business master station. Specifically, NTDClient, CDD Client, and NSD Client can be deployed on the communication control unit, and interact with the communication control unit through a preset interface, such as obtaining various parameters of the communication device through the communication control unit, or sending resource allocation information to the communication device etc., and further implement resource allocation for the communication device. It should be noted that the ICMT unit and the communication control unit as a whole can be regarded as the server side of the entire resource allocation process, and each module of the ICMT unit can be implemented by one or a group of servers, which is not limited in the embodiment of the present invention.

It can be seen from Figure 2B or Figure 2C that during the operation of the power distribution communication network deployed with ICMT units, the starting point and terminal of the service data flow will not change, it is still the service terminal or the service master station, but the intermediate communication process is affected by the ICMT Controlled by the unit, the communication resources required by the service data carried by the service terminal are dynamically allocated by the ICMT unit, and the detailed resource allocation process is shown in Figure 4A.

It should be noted that in practical applications, the modules of TCD Server, NTD Client/Server, CDDClient/Server and NSD Client/Server in the above-mentioned ICMT units can be deployed on one or more network devices, and the network devices can be the above-mentioned communication devices Or the equipment contained in the communication control unit. FIG. 3 shows a schematic structural diagram of a network device according to an embodiment of the present invention. The network device 30 includes: a processor 32 and a network interface 34 .

Processor 32 includes one or more processing cores. The processor 32 executes various functional applications and data processing involved in the resource allocation method of the power distribution communication network described below by running software programs and modules.

There may be multiple network interfaces 34, and the network interfaces 34 are used to communicate with other communication devices, service terminals or network devices.

In a possible implementation manner, the network device 30 further includes components such as a memory 36 and a bus 38 . Wherein, the memory 36 and the network interface 34 are respectively connected to the processor 32 through the bus 38 .

Memory 36 may be used to store software programs as well as modules. Specifically, the memory 36 can store an operating system 362 and an application program module 364 required by at least one function. The operating system 362 may be an operating system such as a real-time operating system (Real Time Executive, RTX), LINUX, UNIX, WINDOWS or OS X.

The resource allocation method provided by the embodiment of the present invention will be explained below with reference to FIG. 4A . Wherein, FIG. 4A only uses the above-mentioned modules of the ICMT unit as an example, and those skilled in the art may also implement modules having the same functions as the modules of the ICMT unit, which is not limited in the embodiment of the present invention.

Fig. 4A is a flow chart of a resource allocation method for a power distribution communication network provided by an embodiment of the present invention. Referring to Fig. 4A, it includes the following steps:

401. After the TCD module detects that the service terminal is connected to the power distribution communication network, it acquires the service of the service terminal and the target resource parameters of the service. The target resource parameters of the service include the target bandwidth, target delay and service priority of the service .

Wherein, the service terminal mentioned in this step may refer to any service terminal connected to the power distribution communication network. A service terminal can carry one or more services, and different services correspond to different service types. Wherein, the embodiment of the present invention is only introduced by taking the resource allocation of one service of the service terminal as an example, and the same is true for other services carried by the service terminal. Before the service terminal is connected to the power distribution communication network, the staff can configure the service type carried by the service terminal and the target resource parameters of each service. For example, the service terminal may have a configuration panel with buttons for configuring the service type and target resource parameters of the service, and the staff may use the configuration panel to configure the service terminal. For example, the target resource parameter may include one or more parameters among parameters such as target bandwidth required by the service, end-to-end target delay, service priority, and data transmission period.

Wherein, the target bandwidth may refer to the minimum bandwidth required for service data transmission, and the target delay may refer to the end-to-end maximum delay of service data transmission. The level of business priority can represent the importance of business data. For example, in order to detect faults in time to ensure the normal operation of the system, the priority of fault detection services can be set higher than that of other services. In one embodiment, the staff can create a service priority list for various services carried in the power distribution network. The service priority list is used to store services and corresponding service priorities. Different services can correspond to different or the same business priority. Subsequent service priorities can be uniformly set for service terminals according to the service priority list, thereby ensuring the uniformity of service priority settings in the power distribution communication network. For example, the service priority list can be preset in each service terminal. Taking a service terminal as an example, after the staff configures the service terminal, the service terminal can automatically determine the configured service according to the service priority list. business priority. Alternatively, the service priority list can be stored in the TCD Server, and when the service terminal is connected to the power distribution communication network, the TCD Server can directly determine the corresponding service priority according to the services configured by the service terminal.

In the embodiment of the present invention, through the interaction between the TCD Client and the TCD Server, the TCD Server can acquire at least one service of the service terminal and target resource parameters of each service. Specifically, the TCD Client is deployed on a service terminal, and at least one preconfigured service and target resource parameters of each service can be obtained from the service terminal through a preset interface. Afterwards, the TCD Client may send the obtained at least one service and the target resource parameters of each service to the TCD Server, and the TCD Server stores the obtained at least one service and the target resource parameters of each service. Wherein, obtaining the service of the service terminal refers to obtaining the service type of the service carried by the service terminal.

Before the TCD Client sends at least one service of the service terminal and the target resource parameters of each service to the TCD Server, the TCD Client will interact with the TCD Server to complete the process of the service terminal accessing the power distribution communication network, see Figure 4B , including the following steps 401a to 401e:

Step 401a: After the service terminal is powered on, the TCD Client starts running.

Step 401b: The TCD Client broadcasts an access request packet, which at least carries the IP address of the TCD Client and the IP address of the TCD Server, and the access request packet may be a UDP data packet.

Step 401c: After receiving the access request packet, the TCD Server sends access configuration information to the TCD Client. The access configuration information may include the IP address of the service terminal, the subnet mask, the gateway, and the IP address of the TCD Server. TCDClient configures the service terminal to establish point-to-point communication between TCD Client and TCD Server.

Step 401d: TCD Client sends a master station configuration request to TCD Server.

Step 401e: After receiving the configuration request of the master station, the TCD Server sends the configuration information of the master station. The configuration information of the master station may include the IP address of the business master station, the port information of the business master station, and the port information of the service terminal, etc. The TCD Client configures the service terminal according to the configuration information of the master station to complete the process of connecting the service terminal to the power distribution communication network.

Through the interaction between TCD Client and TCD Server, the process of automatically connecting business terminals to the power distribution communication network is realized, which overcomes the trouble of manually configuring business terminals one by one to connect to the network, and realizes the immediate Plug and play.

It should be noted that after the service terminal is connected to the power distribution communication network, the staff can also change the service type of the service carried by the service terminal and the target resource parameters of the service on the TCDServer side. The process can be as follows:

When a service change operation on the service terminal is detected, the service type and target resource parameters of the service terminal after the change are obtained; the service type and target resource parameters of the service after change are sent to the service terminal for configuration by the service terminal. Specifically, the TCD Server can provide a service terminal configuration interface. In the service terminal configuration interface, staff can change the service type and target resource parameters of the service carried by the service terminal. Business change operation, obtain the business type and target resource parameters of the business after the business terminal is changed, and send the business type and target resource parameters of the changed business to the TCD Client on the business terminal, and the TCD Client configures the business for the business terminal Type and target resource parameters of the business.

Of course, in addition to updating the service type of the service and the target resource parameters of the service, it is also possible to only change the target resource parameters of the service that have been preset on the service terminal. For example, the pre-set services of the business terminal include business A and business B. The staff can change the business terminal business B to business C on the server side, and can also only change the target resource parameters of business B. The specific situation is determined by It needs to be determined actually, which is not limited in this embodiment of the present invention.

When the current business terminal is connected to the power distribution communication network system, all business-related parameters need to be manually configured on the business terminal. Once it involves the adjustment of target resource parameters or business changes, it will consume a lot of manpower , and make system maintenance very difficult. However, the method provided by the embodiment of the present invention can automatically configure the service terminal when the target resource parameter is adjusted or the service is changed, which saves manpower, reduces the probability of manual configuration errors, and improves the deployment efficiency of the system.

In the embodiment of the present invention, the service terminal may be a service terminal newly connected to the power distribution communication network, that is, a newly added service terminal, or it may be used to replace an original service terminal. Specifically, a usage identifier can be configured for a service terminal to indicate whether the service terminal is a new service terminal or is used to replace an original service terminal. Correspondingly, the process of obtaining the target resource parameters of each service of the service terminal can be as follows:

If the service terminal is a newly added service terminal, the TCD Server obtains the target resource parameter of the service of the service terminal through the TCD Client.

If the service terminal is used to replace the original service terminal, after the TCD Server obtains the target resource parameter of the service of the service terminal, compare the target resource parameter of the service of the original service terminal with the target resource parameter of the service of the service terminal Whether they are consistent; if not, send the target resource parameters of the service of the original service terminal to the service terminal for configuration by the service terminal. Specifically, if the comparison results are inconsistent, the TCD Server sends the target resource parameters of the service of the original service terminal to the TCD Client on the service terminal, and the TCD Client performs configuration.

For the connected service terminal, different processing is carried out according to the different purposes of the service terminal, and when the service terminal is used to replace the original service terminal, the target resource parameters can be automatically configured for the service terminal, so that the access of the service terminal More flexible, smarter.

402. The NTD module generates network topology information of the power distribution communication network according to the connection relationship between devices in the power distribution communication network.

The NTD module of the ICMT unit can obtain the device connection relationship set of each device in the power distribution communication network, and generate the network topology information of the power distribution communication network according to the device connection relationship set of each device. The specific process can be as follows:

The NTD Client can be deployed in the communication control unit, and obtain the set of device connection relationships of each device from the communication control unit through a preset interface. Specifically, the acquisition may include: for each communication device in the power distribution communication network, NTD Client obtains the first device set that has a connection relationship with the communication device; for each service in at least one service terminal of the power distribution communication network For a terminal, the NTD Client acquires a second device set that has a connection relationship with the service terminal. Afterwards, the NTD Client sends the obtained set of device connection relationships of each device to the NTD Server, and the NTD Server generates network topology information based on the first set of devices of each communication device and the second set of devices of each service terminal, and stores The network topology information. After generating and storing the network topology information of the power distribution communication network, the NTD Server can directly obtain the stored network topology information.

Wherein, the NTD Client can obtain the device connection relationship set of each device in the power distribution communication network at regular intervals, and can also acquire it when it detects that the device connection relationship changes, which is not limited in the embodiment of the present invention.

Wherein, for each communication device in the power distribution communication network, the communication device may store a routing table locally, and the routing table stores routing information, and the routing information is used to indicate the optional next hop of the communication device The IP address of the communication device. The NTD Client can determine other communication devices that have a connection relationship with the communication device through the routing table.

403. The NTD module determines the current communication path between the service terminal and the service master station according to the network topology information, where the current communication path consists of at least one first communication device.

For each communication device in the power distribution communication network, NTD Client can also determine the next-hop communication device currently selected by the communication device according to the routing table of the communication device, and the next-hop currently selected by each communication device The communication device sends it to the NTD Server, and the NTD Server determines the current communication path from the service terminal to the service master station according to the next-hop communication device currently selected by each communication device. Wherein, since the service terminal can also be regarded as a communication device, the communication device indicated by the next hop of the service terminal can also be determined according to the routing information of the service terminal.

404. The CDD module acquires interface attribute information of the interface of each communication device in the power distribution communication network, where the interface attribute information includes interface bandwidth information, cache information, and priority information.

The CDD module of the ICMT unit can obtain the interface attribute information of each interface of each communication device in the power distribution communication network. The specific process can be as follows: the CDD Client can be deployed in the communication control unit. For each communication device, the CDDClient can obtain attribute information of each interface of the communication device from the communication control unit through a preset interface, and send the interface attribute information of each interface of the communication device to the CDD Server.

Wherein, the interface attribute information is used to indicate the data transmission capability of the interface. A communication device may have one or more interfaces, and each interface corresponds to a certain data transmission capability, and the data transmission capability of an interface may be represented by interface attribute information such as interface bandwidth information, cache information, and priority information. Wherein, the bandwidth information may also include used bandwidth information and unused bandwidth information. For example, assuming that a certain interface has a bandwidth of 2M, and currently only carries one service, and a 1M bandwidth is allocated for the service, then the interface's The used bandwidth is 1M, and the unused bandwidth is 1M.

Wherein, each interface has a certain buffer area, and the buffer area may be composed of multiple queues, and each queue corresponds to a certain priority. The buffer information of each interface may include information such as the size of the buffer area of the interface, the number of queues into which the buffer area is divided, and the size of each queue. The priority information of the interface includes the priority of each queue forming the buffer area of the interface, and the interface forwards the data in the queue with higher priority first. In practical applications, multiple interfaces of a communication device can share a general buffer area, and the communication device can divide a part of the buffer area from the total buffer area as the interface buffer area according to the configuration information of the buffer area to form a queue of the interface buffer area The number, the length of each queue and the priority of each queue can be adjusted. In addition, the cache information in the above interface attribute information may also include the number of used queues and the number of unused queues, and the priority information may also include information such as the priority of used queues and the priority of unused queues.

It should be noted that the order in which steps 401 to 404 are arranged above does not represent the order in which they are executed, and they may be executed simultaneously or separately, which is not limited in this embodiment of the present invention.

405. The NSD module generates resource allocation information of at least one first communication device according to target resource parameters of the service, network topology information, and interface attribute information of each communication device.

The NSD module is the core computing unit of ICMT. The NSD Server can obtain the business terminal business and business target resource parameters from the TCD Server, and the network topology information of the power distribution communication network and the current time of the business terminal and the business master station from the NTD Server. The communication path acquires interface attribute information of each interface of each communication device from the CDD Server, and then generates resource allocation information of at least one first communication device according to the acquired information. Among them, TCD Server, NTD Server and CDD Server can also actively send the acquired data to NSD Server.

Taking any service of the service terminal as an example, the process of generating resource allocation information will be introduced below, which may include the following steps 405a to 405d:

Step 405a: For each first communication device in at least one first communication device, the NSD Server determines a first interface of the first communication device.

Wherein, the first interface refers to an interface used to transmit data of the service.

Step 405b: The NSD Server generates bandwidth configuration information of the first communication device according to the target bandwidth of the service and the bandwidth information of the first interface.

If the unused bandwidth information of the first interface is greater than the target bandwidth of the service, the bandwidth configuration information may be used to instruct the first communication device to allocate the target bandwidth for the service. If the unused bandwidth information of the first interface is smaller than the target bandwidth of the service, the bandwidth configuration information may be used to instruct the first communication device to allocate all unused bandwidth information to the service.

Step 405c: The NSD Server generates cache configuration information of the first interface according to the bandwidth configuration information, target delay, and cache information.

The cache configuration information is used to configure the cache information of the first interface of the first communication device, including the configuration of the buffer size allocated by the first communication device for the first interface, the number of queues in the buffer area, and the size of each queue.

Since the size of the buffer area of the first interface and the composition of the queue directly affect the bandwidth utilization rate of the first interface and the transmission delay of service data, for example, the bandwidth allocated by the first interface for carrying services is 1M, then If the size of the buffer area of the first interface is 400K, the first interface obtains at most 400K data from the buffer area at one time, and the bandwidth utilization rate is only 40%, resulting in a waste of bandwidth resources. If the size of the buffer area of the first interface is 1M or more, the bandwidth utilization rate can reach 100%, and if the buffer area of the first interface is divided into 10 queues of equal size, the first interface carries two services, as Among them, service A is allocated 8 queues, service B is only allocated 2 queues, and the target delay of service B is less than the target delay of service A, so the delay of transmission service B is likely to be relatively large, which does not satisfy its target latency.

Therefore, the NSD Server can comprehensively determine the cache configuration information of the first interface according to the bandwidth configuration information of the first interface, the target delay of the service, and the current cache information of the first interface. For example, the NSD Server can determine the used bandwidth of the first interface according to the bandwidth configuration information of the first interface, that is, the bandwidth allocated for the carried service; if the buffer size indicated by the cache information of the first interface is If the used bandwidth of the first interface is satisfied, the time delay of the first interface is calculated according to the used bandwidth of the first interface and the cache information of the first interface; if the time delay of the first interface of each communication device and less than or equal to the target delay of the service, there is no need to configure the cache information of the first interface of the communication device; if the delay sum of the first interface of each communication device is greater than the target delay of the service, it is necessary to configure the The cached information of the first interface of the one or more first communication devices is reconfigured. Specifically, the method for determining that the cached information of the communication device needs to be reconfigured may be: according to the target delay of the service and the number of at least one first communication device, determine the average target time of the service at each first communication device Delay, if the delay of the first interface of a certain communication device is greater than the average target delay, reconfigure the cached information of the first interface of the communication device.

Step 405d: The NSD Server generates priority configuration information of the first interface according to the service priority of the service and the service priorities of other services corresponding to the first interface.

The priority configuration information is used to instruct the first interface to allocate a buffer queue with an appropriate priority for the service. As described in step 404 above, the first interface preferentially processes and caches service data with high priority. For example, if the priority of this service is higher than that of other services on the first interface, the priority configuration information can be used to indicate that the queue with the highest priority is used to cache the service data of this service, and the cache of other services The queue priority is adjusted according to the business priority.

Wherein, the resource allocation information includes the above-mentioned bandwidth configuration information, buffer configuration information and priority configuration information. Step 405b, step 405c, and step 405d may be executed simultaneously or separately, which is not limited in this embodiment of the present invention.

406. The NSD module sends the resource allocation information of the at least one first communication device to the at least one first communication device, where the resource allocation information is used by the at least one first communication device to configure resources.

This step can be performed by the NSD module of the ICMT unit, and the sending process can be as follows: the NSD Server sends the generated resource allocation information of at least one first communication device to the NSD Client, and the NSD Client translates the resource allocation information into communication control corresponding to the communication device instruction, and then send the communication control instruction of at least one communication device to the at least one communication device. Specifically, the NSD Client can be deployed in the communication control unit, and the communication control instruction is sent to at least one communication device through the communication control unit. Each communication device in the at least one communication device performs resource allocation according to the received communication control instruction.

It should be noted that since the service terminal can also be regarded as a communication device, the ICMT unit can also allocate resources to the service terminal. Wherein, after the TCD Client deployed on the service terminal receives the communication control instruction for resource allocation, it configures the service terminal.

Steps 401 to 406 are the process of dynamically allocating resources for the service terminal. During the operation of the service terminal, the ICMT unit can also monitor the operating status of the communication equipment, which includes normal status and fault status. The monitoring process can be performed by The execution by the NTD module of the ICMT unit may also be executed by the CDD module of the ICMT unit, which is not limited in this embodiment of the present invention. If it is found that the current communication path of the service terminal fails, the ICMT unit may reassign the communication path for the service terminal. Referring to FIG. 4C, the embodiment of the present invention may also include the following steps 407 to 409:

407. When detecting that the current communication path of the service terminal includes the second communication device, the NSD module determines an alternative communication path of the service terminal according to the network topology information.

Wherein, the second communication device refers to a device in a fault state in the current communication path, that is, the first communication device in a fault state in the current communication path.

After the NSD Server of the ICMT unit obtains the network topology information of the power distribution communication network and the current communication path of the service terminal from the NTD Server, it can calculate one or more alternatives for the service terminal according to the device connection relationship of each communication device. communication paths, and store the one or more alternative communication paths. When the ICMT unit detects that the current communication path of the service terminal includes the second communication device, that is, when the current communication path fails, it can select an alternative communication path from one or more alternative communication paths. Wherein, when there are multiple candidate communication paths, the manner of selecting the candidate paths may be random selection, or may be selected according to a preset order, which is not limited in this embodiment of the present invention.

Certainly, the NSD module of the ICMT unit may also temporarily calculate an alternative communication path when detecting that the current communication path fails. The embodiment of the present invention does not limit the calculation timing of the alternative communication path.

408. The NSD module determines target routing information of the third communication device according to the current communication path and the candidate communication path.

Wherein, the third communication device refers to a communication device that needs to change routing information in the alternative communication path, and the target routing information is used to replace the routing information of the third communication device.

409. The NSD module sends the target routing information of the third communication device to the third communication device, and the third communication device is configured to perform configuration according to the routing information.

The NSD Server of the ICMT unit can send the target routing information of the third communication device to the NSD Client, and the NSD Client translates the target routing information of the third communication device into a communication control instruction of the third communication device and sends it to the third communication device, so that The third communications device is capable of changing the routing information for the target routing information.

Steps 407 to 409 are the process of reallocating communication paths for service terminals. By dynamically allocating communication paths for service terminals, the normal operation of each service terminal in the power distribution communication network is ensured, and the maintenance efficiency of the power distribution communication network is improved. . Of course, in order to ensure that the redistributed communication path can meet the needs of the service carried by the service terminal for communication resources, after the redistributed communication path, the ICMT unit can also calculate whether the communication resources allocated by the redistributed communication path meet the needs of the service terminal. If the business requirements are not satisfied, resource allocation can be re-allocated for the communication devices included in the reallocated communication path according to the business needs of the service terminals.

From the above steps 401 to 409, it can be seen that through the interaction between the various modules of the ICMT unit, and the interaction between each module and the equipment in the power distribution communication network, the actual demand for communication resources according to the business carried by the service terminal is realized. In the process of resource allocation and communication path change, in order to more intuitively represent the data interaction between the modules of the ICMT unit, FIG. 4D shows a schematic diagram of the data interaction between the modules of the ICMT unit.

In order to enable the various modules of the ICMT unit to exchange data without barriers, each module in the embodiment of the present invention uses a unified description language to describe the data that needs to be interacted with, and transmits data through a description file in a unified format. For example, you can SCL (Substation Configuration Language, substation configuration description language) language based on XML (Extensible Markup Language, Extensible Markup Language) is uniformly used for description, and XML files are used to transfer data. Specifically, according to the difference in transmission data required by different modules, corresponding description models can be established for different modules, and the description models of different modules are described using the above-mentioned unified language. Among them, the description model is used to standardize the type, description method, and naming rules of the data that need to be described.

Among them, taking the SCL language as an example, the description model construction method of each module of the ICMT unit is as follows:

(1) Modeling method of TCD description model

Let the service type be set BK, the target resource parameter of the service be set BA, the type of service terminal be set TK, and the target resource parameter for a certain service be set TKA,

Bk={bk1,bk2,bk3,...,bkn},

BA＝{ba1,ba2,ba3,...,ban}

TK＝{tk1,tk2,tk3,...,tkn}

TKA={bk, tka1, tka2, tka3,...,tkan}

Take the three remote services of distribution automation system as an example, BK={remote signaling, telemetry, remote control}

BA={source address, source port, destination address, destination port, minimum packet size, maximum packet size, minimum bandwidth requirement, maximum bandwidth requirement, end-to-end maximum delay time, priority number}

TK = {TTU, FTU, DTU, fault indicator}

For example, the target resource parameters of remote signaling services can be expressed as: TK(yx)={service type=remote signaling, minimum packet size=xx, maximum packet size=xx, minimum bandwidth requirement=xx, maximum bandwidth requirement=xx , end-to-end maximum delay time = xx, priority number = xx}. Among them, yx represents remote signaling.

Finally, the above description model is described by using SCL language to form a file in XML format, so that barrier-free communication between modules can be realized. For example, the TCD description model uses the SCL language to describe the structure as shown in Table 1:

(2) Modeling method of NTD description model

Let the network topology information set of the power distribution communication network be N, where the communication device node set is D, where the communication device is dn, A is the set of all attributes of the communication device d1-dn, and DR is the connection relationship with the communication device di The set of devices, the attribute set dnA of the communication device dn is the complete set or subset of A.

In this way, the network topology containing n communication devices can be described as:

N={DR1,DR2,DR3,...,DRn}, D={d1,d2,d3,...dn}, DRi={di,dx,dy...}, A={a1,a2,a3,..., an}, d1A={ax1,ay1,az1...},d2A={ax2,ay2,az2}

Let a certain service terminal be sti, and the service master station be MS. In this way, the communication path from a certain service terminal to the master station can be described as: stiMS={sti,dx,dy,dz,...,MS}. Among them, sti, dx, dy, dz, MS are used to indicate the ordered connection relationship of devices on the communication path.

Assuming that there are n service terminals in the power distribution communication network, let the set of communication paths from all service terminals to the service master station in the full distribution and use communication network be STMS, then STMS={st1MS,st2MS,...,stnMS}.

Finally, the above description model is described by using SCL language to form a file in XML format for communication. For example, the TCD description model uses XML language to describe the structure as shown in Table 2:

(3) Modeling method of CDD description model

According to the NTD description model modeling method, the communication device node set is D, where the communication device is dn, A is the set of all attributes of the communication device d1-dn, and DR is the other device that has a connection relationship with the communication device di The device set, the attribute set dnA of the communication device dn is a complete set or a subset of A. The abstraction of this part can be used as the basis of the CDD description model of communication equipment. The focus of the CDD model is to standardize the element definitions of the A set.

The definition A set contains the following elements:

A={a1 (equipment number), a2 (equipment name), equipment type, equipment interface type, total number of equipment interfaces, number of used interfaces, number of unused interfaces, equipment interface set AI, equipment interface attribute AIN}.

Wherein, AI is a set of device interfaces of the communication device, AI={I1, I2, I3, . . . , In}. The device interface attribute AIN is used to describe the attribute of the device interface, AIN={ai1 (bandwidth information), ai2 (maximum delay time of interface data forwarding), ai3 (currently used processing capacity), ai4 (remaining processing capacity), ai5 ( Maximum data buffer), ai6 (used buffer size), ai7 (remaining buffer size), ai8 (maximum queue length), ai9 (used queue length), ai10 (remaining queue length), ai11 (used first number of levels), ai12 (number of unused priority levels)...}.

Finally, the above description model is converted into a file describing the structure in XML language for communication. For example, the TCD description model uses XML language to describe the structure as shown in Table 3:

(4) Modeling method of NSD description model

When TCD Server, CDD Server, and TCD Server are updated, they will actively send the information to NSDServer. The NSD Server calculates resource allocation information according to the received description model, and generates an NSD description model, that is, generates an XML file for describing resource allocation information. Afterwards, the generated XML file describing the resource allocation information is passed to the NSD Client, and the NSD Client analyzes the XML file, translates it into a communication control command, and sends it to the communication device or service terminal. Wherein, in the NSD description model, descriptions of communication devices, communication device interfaces, interface attribute information, etc. are the same as those described above for communication devices, communication device interfaces, interface attribute information, etc., so as to ensure that the description method and communication Normative uniformity.

At the same time, through the interaction between the TCD Client and the TCD Server, the access configuration of the power distribution communication network can be automatically configured for the business terminal, realizing the process of automatically connecting the business terminal to the power distribution communication network, and overcoming the problem that can only be done manually one by one. The trouble of configuring the service terminal to access the network realizes the plug-and-play of the service terminal.

Furthermore, during the operation of the service terminal, the server can adjust the target resource parameters or change the service for the service terminal, which saves manpower, reduces the probability of manual configuration errors, and improves the deployment efficiency of the system.
