[0051] In order to better understand the present invention, the present invention is further described below with reference to the accompanying drawings and examples.

[0052] Example 1:

[0053] The circuit breaker access method based on topology identification provided by the present invention involves a fusion terminal, a circuit breaker device and a master station; the fusion terminal side realizes automatic access to the circuit breaker device by obtaining the communication address and device ID of the circuit breaker device, and realizes the verification of the substation equipment through the topology identification command to generate the graphic model information. The fusion terminal uploads the generated graphic model information to the master station, completes the update of the circuit breaker information on the master station side, realizes the bottom-up adaptive access of the circuit breaker device, and reduces the workload of the master station side and the field side operation and maintenance. When the circuit breaker device in the present invention leaves the factory, the communication address is preset inside the circuit breaker device, and the communication address is ensured to be unique. The low-voltage intelligent circuit breaker device has a topology identification function.

[0054] Among them, the present invention is based on the circuit breaker access method based on topology identification provided by the fusion terminal, such as Figure 1 Shown, including:

[0055] S1-1. After the circuit breaker equipment is powered on and networked successfully, the fusion terminal obtains the communication address of each circuit breaker equipment;

[0056] S1-2. The fusion terminal obtains the circuit breaker device ID according to the communication address of each circuit breaker device, and completes the circuit breaker device registration based on the circuit breaker device ID;

[0057] S1-3. The fusion terminal initiates topology identification to each circuit breaker device to obtain a topology identification result;

[0058] S1-4. The fusion terminal verifies the substation affiliation of each circuit breaker device based on the topology identification results and the communication addresses of each circuit breaker device, and generates substation map information based on the verification results.

[0059] S1-5. The fusion terminal sends the image model information to the master station to complete the access of the circuit breaker device to the master station side.

[0060] The present invention is based on a circuit breaker access method based on topology identification provided by a circuit breaker device, such as Figure 2 Shown, including:

[0061] S2-1. The circuit breaker device is powered on and the communication address of the circuit breaker device is sent to the fusion terminal;

[0062] S2-2. The circuit breaker device sends the device ID to the fusion terminal to complete the registration;

[0063] S2-3. The circuit breaker device cooperates with the fusion terminal to perform topology identification to implement the substation ownership verification of the circuit breaker device.

[0064] Therefore, the circuit breaker access method based on topology identification implemented by the cooperation of the fusion terminal and the circuit breaker equipment is mainly divided into three steps, namely, power-on registration of the substation circuit breaker equipment (such as steps S1-1 and S1-2 and S2-1 and S2-2), verification of the substation circuit breaker equipment (steps S1-3 and S1-4 and S2-3), and update of the master station model information (step S1-5).

[0065] Phase 1: Circuit Breaker Equipment Registration

[0066] This stage mainly realizes the search for the address of the circuit breaker device, the registration of the circuit breaker device information, and the verification of the communication status. This stage is based on the normal communication network, the normal connection of the circuit breaker device line, and the normal communication conditions of the circuit breaker device. This process covers three situations: the first power-on of a new fusion terminal, the power-on of the original area fusion terminal after a power outage in the area, and the installation of the fusion terminal used in other areas into the new area. The detailed process is as follows Figure 3 shown.

[0067] (1) Turn on the circuit breaker.

[0068] (2) After the network is successfully established, the fusion terminal obtains the communication address of the circuit breaker device.

[0069] (3) The fusion terminal sends a device ID information query command to the circuit breaker device according to the address list.

[0070] (4) The circuit breaker device receives the device ID command and returns the device ID information, including the device type, manufacturer code, production batch number and other information.

[0071] (5) The fusion terminal receives the device ID information and parses the ID information to determine the type of circuit breaker device, eliminating non-circuit breaker devices such as meters and sensors.

[0072] (6) The fusion terminal sends a registration success message.

[0073] (7) The circuit breaker device receives the registration success message, and the circuit breaker device registration is completed.

[0074] Phase II: Identification of substation topology and verification of substation circuit breaker equipment

[0075] This phase begins after the device registration is completed. The topology identification of the substation is performed to realize the correspondence between the communication address of the circuit breaker device and the topology hierarchy, and to verify whether the registered circuit breaker belongs to this substation. The detailed process is as follows: Figure 4 The main process is as follows:

[0076] (1) The fusion terminal starts the topology identification process.

[0077] (2) The circuit breaker device completes the topology identification action as required.

[0078] (3) The fusion terminal receives the topology identification information and completes the topology identification. The topology information includes information such as the communication address of the circuit breaker device, and realizes the correspondence between the communication address and the topological hierarchy of the circuit breaker device.

[0079] (4) The fusion terminal verifies the communication address of each circuit breaker device based on the topology information. If the communication address is consistent, the circuit breaker information is retained and added to the whitelist; if it is inconsistent or there is no such communication address, the corresponding circuit breaker device is cancelled and recorded as non-local equipment, including equipment in other substations, equipment that cannot communicate, topology abnormalities, maintenance trips, faults, etc., to complete the substation access equipment verification and generate substation diagram information.

[0080] The topology identification achieved by the fusion terminal and circuit breaker equipment in the present invention requires the circuit breaker equipment to have a topology identification function. The topology identification here can be: the fusion terminal sends a topology identification command, the circuit breaker equipment initiates the topology identification action and sends topology identification information to the fusion terminal; the fusion terminal receives the topology identification information sent by each circuit breaker to obtain the topology identification result. The present invention supports multiple topology identification methods, including big data analysis and topology identification methods based on characteristic signal injection. Topology identification requires the installation of a topology identification app on the fusion terminal, and topology identification analysis based on a specific algorithm to obtain the substation topology identification result. The substation topology identification result includes: the hierarchical relationship of the circuit breaker equipment, the communication address, and the device ID.

[0081] Phase 3: Update of main site model information

[0082] The fusion terminal uploads the generated substation circuit breaker equipment diagram information to the master station, which updates the information and completes the circuit breaker access on the master station side.
