In some embodiments, the edge gateway may format the packets during the communication. For example, the edge gateway may convert a packet sent by the edge device into a data format that can be recognized by the end device. The edge gateway can also uniformly convert the data packets sent by the end equipment into a data format which can be identified by the edge equipment. Therefore, the embodiment of the invention realizes normal communication between the edge equipment and the end equipment by arranging the edge gateway in the framework of the power distribution station area, and meets the requirement of diversified development of the end equipment.
As shown in fig. 2, based on the power distribution substation architecture shown in fig. 1, an embodiment of the present invention provides a power distribution substation edge device communication method based on IPV6, which is applied to an edge gateway, where the edge gateway is connected to an edge device and an end device respectively, and the method includes steps S301 to S304.

The embodiment of the invention sets different execution protocols according to different types of end equipment. The execution protocol is used for converting data packets in other data formats into data formats supported by the end device. The execution specification of the end device is used for determining the data format supported by the end device. Therefore, the embodiment of the invention can convert the data format of the data packet based on the execution protocol of the end equipment, so that the received data packet can be identified and analyzed by various types of end equipment in the power distribution area, thereby meeting the requirement of diversification of the end equipment.
And S303, packaging the execution protocol based on the end equipment and the first data request to obtain a second data request with a data format supported by the end equipment.
In some embodiments, the second data request is for instructing the end device to perform a set operation. Illustratively, the second data request may include data information of the setting operation.

And S304, sending a second data request to the end equipment based on the IPV6 address to instruct the end equipment to execute the setting operation.
The invention provides a power distribution station area edge device communication method based on IPV6, which is characterized in that an edge gateway is arranged between an edge device and an end device, and the edge gateway realizes communication between the edge devices in the power distribution station area. In one aspect, the edge gateway establishes a mapping relationship between the identification information of the end device, the IPV6 address, and the enforcement conventions. When receiving the first data request sent by the edge device, the edge gateway may determine an IPV6 address and an execution protocol of the end device based on the identification information of the end device, so that the edge gateway may perform IPV6 address coding for the end device and perform communication based on the IPV6 technology. On the other hand, the edge gateway may encapsulate, based on an execution protocol of the end device, a setting operation that the end device needs to execute by the edge device into a data format supported by the end device, that is, a second data request, so that after the edge gateway sends the second data request to the end device, the end device may identify the second data request, thereby implementing communication between the edge device and the end device.

And S310, sending the execution result of the setting operation to the side equipment to complete the communication between the side equipment and the end equipment.
As a possible implementation manner, the edge gateway may perform IP encapsulation on an execution result of the setting operation to obtain a first data response; the first data response is sent to the edge device.
In this way, the embodiment of the present invention may send the execution result of the side device request to the side device after receiving the first data request of the side device, thereby completing the communication between the side device and the end device. In the process, the edge gateway can convert the data format based on the execution protocol of the end equipment, so that the edge equipment and the end equipment can identify the received data packet, and the requirement of diversified development of the end equipment is met while the communication of the edge equipment of the power distribution station area is realized.
Optionally, as shown in fig. 4, an embodiment of the present invention further provides a power distribution area edge device communication method based on IPV6, where the method includes steps S401 to S406.
S401, receiving a registration request of the terminal equipment.
Wherein the registration request includes identification information of the end device.
In some embodiments, the registration request is for requesting the edge gateway to register the peer device.
S402, sending a first verification request to the edge device.

As a possible implementation manner, after receiving a first authentication request sent by an edge gateway, an edge device may authenticate, based on the first authentication request, whether an end device is a local device, and generate a first authentication response.
Illustratively, the edge device stores a device directory of the local device in advance. The side device may query, based on the identification information of the end device, a device directory pre-stored in the side device, and determine whether the end device exists in the device directory, thereby verifying whether the end device is the local device.
S404, determining whether the end equipment is the local area equipment or not based on the first verification response.
And S405, if so, sending a registration confirmation frame to the end equipment to indicate that the end equipment is successfully registered.

Therefore, when determining that the end device is the local device, the edge gateway may establish a mapping relationship between the identification information of the end device, the execution protocol, and the IPV6 address, store the mapping relationship in a mapping table, and complete registration of the end device, so that when the edge device communicates with the end device, the edge gateway queries the end device, and thus, the success of communication between the edge device and the end device is ensured.
It should be noted that the edge gateway may assign the IPV6 address to the end device when receiving a registration request from the end device. Alternatively, the edge gateway may also assign the IPV6 address to the end device prior to receiving a registration request for the end device.

S503, sending a networking response to the end equipment, wherein the networking response comprises the IPV6 address of the end equipment.
In this way, the edge gateway may allocate the IPV6 address to the end device before receiving the registration request from the end device, so as to facilitate the registration process of the end device.
As shown in fig. 3, based on the framework of the power distribution grid shown in fig. 1, an embodiment of the present invention provides a power distribution grid edge device communication method based on IPV6, which is applied to an end device, where the end device is connected to an edge device through an edge gateway, and different types of end devices have different types of execution protocols; the method comprises steps S304-S307.
And S304, receiving a second data request sent by the edge gateway.
And the second data request is used for indicating the end equipment to execute the setting operation. Illustratively, the second data request may include data information of the setting operation.
S305, analyzing the second data request based on the execution protocol of the end equipment, and executing the setting operation to obtain an execution result.
Wherein the execution specification corresponds to a data format of the second data request.
For example, if the end device is a smart meter and the setting operation is returning the metering data, the execution result is the metering data of the smart meter.
As another example, assuming that the end device is a smart breaker, the setting operation is to turn off the smart breaker, and the execution result is information indicating that the smart breaker has been turned off.
