In this embodiment, a method for positioning a terminal of an electric power internet of things is provided, which may be used for a terminal of an electric power internet of things, and fig. 1 is a flowchart of a method for positioning a terminal of an electric power internet of things according to an embodiment of the present invention, as shown in fig. 1, the flowchart includes the following steps:

s11, acquiring an IPv6 address of the power Internet of things terminal, wherein the IPv6 address comprises a network identification domain, a positioning updating request domain and a positioning information domain.

The IPv6 address is the uniqueness of the electric power Internet of things terminal, and the unique electric power Internet of things terminal can be determined in the electric power Internet of things through the IPv6 address. The power internet of things terminal can determine the IPv6 address for representing the uniqueness of the power internet of things terminal by inquiring the attribute of the power internet of things terminal.

The coded bit resource of the IPv6 address is rich, and the IPv6 address can be divided into a network identification field, a positioning updating request field and a positioning information field. The network identification domain stores a network address domain and an interface ID domain, the network address domain stores a network address of the power Internet of things terminal, the interface ID domain stores interface information of the power Internet of things terminal, and the power Internet of things terminal can be uniquely identified through codes in the network identification domain; the positioning updating request domain is used for storing positioning updating request information of the power Internet of things terminal; the positioning information field is used for storing the position information of the power internet of things terminal, and the position information comprises a physical position and a logical position.

The electric power internet of things terminal can initiate a position updating request at regular time or at irregular time, and when the electric power internet of things terminal determines that the electric power internet of things terminal needs to update the position information, the electric power internet of things terminal can modify the coding information of the positioning updating request domain to obtain the updated first target IPv6 address of the positioning updating request domain.

For example, the location update request field occupies 1bit in the IPv6 address, the default coding information is 0, and when the location information needs to be updated, the power internet of things terminal may modify the coding information in the location update request field to 1.

S13, packaging an uplink communication data packet of the power Internet of things terminal based on the first target IPv6 address, sending the uplink communication data packet to at least one access node, and determining whether the power Internet of things terminal initiates a positioning updating request or not by the at least one access node according to a positioning updating request domain in the uplink communication data packet.

The manner in which data is encapsulated according to a communication protocol is known to those skilled in the art and will not be described in detail herein.

When the position information of the terminal of the power internet of things needs to be updated, the positioning update request field in the IPv6 address of the terminal of the power internet of things can be modified, but only the IPv6 address set by the terminal of the power internet of things is updated at the moment, the access node and the edge internet of things proxy equipment do not know the change of the IPv6 address of the access node, and when the terminal of the power internet of things is in data communication with the access node, the updated IPv6 address of the access node can be written in the source address of an uplink communication data packet sent to the access node, so that the access node can obtain a request for updating the positioning information when receiving the uplink communication data packet.

The target access node is the nearest access node to the power Internet of things terminal. Correspondingly, the power internet of things terminal can receive a downlink communication data packet sent by the target access node and identify the downlink communication data packet through the coding information in the network identification domain.

And S15, analyzing the target IPv6 address in the downlink communication data packet, and updating the IPv6 address of the power Internet of things terminal by using the target IPv6 address.

The power internet of things terminal analyzes the received downlink communication data packet according to a decoding rule specified by a communication protocol to obtain a target IPv6 address carried by the downlink communication data packet, wherein the target IPv6 address is the latest address given by the edge internet of things proxy equipment in response to the positioning update request, and is the latest IPv6 address of the power internet of things terminal. The electric power internet of things terminal acquires the coding information of the positioning information domain and the positioning updating request domain from the target IPv6 address, and the positioning information domain in the IPv6 address when the electric power internet of things terminal sends an uplink communication data packet is updated by the positioning information domain in the target IPv6 address, so that the position information of the electric power internet of things terminal is up-to-date, and the position information of the electric power internet of things terminal can be conveniently extracted at any time. Meanwhile, in order to avoid repeated triggering of the location update request, the location update request field in the destination IPv6 address is already restored to a non-update state, and the power internet of things terminal can restore the location update request field in its IPv6 address according to the information.

According to the positioning method of the power internet of things terminal, the power internet of things terminal simultaneously gives the network identifier, the positioning update request and the positioning information in the IPv6 address, and on the premise that the uniqueness of the network identifier is ensured, the waste of the IPv6 address on communication resources can be avoided. By fusing the IPv6 network address and the positioning information, the terminal positioning information is borne by the IPv6 address of the power Internet of things terminal, the positioning process is effectively simplified, the service bearing capacity of the terminal is reduced, and the use efficiency of communication resources of the power Internet of things terminal is improved.

For example, the location update request information corresponding to the location update request domain defaults to 0, and when the location update request information is 1, it indicates that the power internet of things terminal initiates a location update request; and when the positioning updating request information is 0, indicating that the electric power internet of things terminal does not initiate a positioning updating request.

Correspondingly, the target access node can send the downlink communication data packet to the power internet of things terminal, so that the power internet of things terminal updates its own IPv6 address according to the destination IPv6 address carried by the downlink communication data packet.

In the positioning method of the power internet of things terminal provided by this embodiment, the access node can determine whether the power internet of things terminal sends a positioning update request by analyzing the uplink communication data packet, and when it is determined that the power internet of things terminal sends the positioning update request, the access node transmits signal parameter information when the uplink communication data packet reaches the access node to the edge internet of things agent for processing the positioning update request, and can receive the downlink communication data packet sent by the power internet of things terminal and send the downlink communication data packet to the power internet of things terminal for position update. Therefore, the position of the power internet of things terminal can be updated through conventional communication data packet transmission, the positioning updating period is shortened, and the real-time performance of position updating is improved.

and S51, receiving signal parameters corresponding to the power Internet of things terminal and sent by at least one access node.

Each access node in communication connection with the power internet of things terminal can receive the uplink communication data packet sent by the access node and forwards the uplink communication data packet to the edge internet of things agent equipment. Accordingly, the edge internet of things agent device can send signal parameters about the same power internet of things terminal by each access node.

For the description of the signal parameters, reference is made to the corresponding related description of the above embodiments, and details are not repeated here.

And S52, calculating the current position information of the power Internet of things terminal based on the information parameters.

The edge Internet of things agent equipment can calculate the physical position information and the logic position information of the current position of the power Internet of things terminal through a preset positioning algorithm. For example, by adopting a three-point distance measurement positioning method, the edge internet of things proxy device can receive signal parameters of at least three access nodes about the same electric power internet of things terminal, calculate the distance from the electric power internet of things terminal to each access node by combining the three-point distance measurement positioning method and the corresponding signal parameters of each access node, and determine the physical position information of the electric power internet of things terminal according to the distance.

Meanwhile, the edge Internet of things agent equipment can verify and determine the logic position information of the electric Internet of things terminal through the acquired signal parameters. For example, the electric power internet of things terminal is located inside or outside the electric power equipment, the signal strength of the electric power internet of things terminal has different value ranges, and the logic position information of the electric power internet of things terminal can be determined by comparing the value ranges of the signal strength corresponding to the signal parameters.

And then the downlink communication data packet is sent to a target access node, and the target access node forwards the downlink communication data packet to the power Internet of things terminal.

According to the positioning method of the power internet of things terminal, after the edge internet of things agent equipment receives signal parameter information about the same power internet of things terminal, the current position of the power internet of things terminal is calculated according to the signal parameter, and the current position of the power internet of things terminal is packaged into the downlink communication data packet, so that the access node can send the downlink communication data packet to the power internet of things terminal, and the power internet of things terminal can analyze the current position information from the downlink communication data packet when receiving the downlink communication data packet. Therefore, the position of the power internet of things terminal can be updated through conventional communication data packet transmission, the positioning updating period is shortened, and the real-time performance of position updating is improved.

In this embodiment, a method for positioning an electric power internet of things terminal is provided, which may be used for an edge internet of things agent device, and fig. 6 is a flowchart of a method for positioning an electric power internet of things terminal according to an embodiment of the present invention, as shown in fig. 6, the flowchart includes the following steps:

and S61, receiving signal parameters corresponding to the power Internet of things terminal and sent by at least one access node. For a detailed description, refer to the corresponding related description of the above embodiments, which is not repeated herein.

And S62, calculating the current position information of the power Internet of things terminal based on the information parameters. For detailed description, reference is made to the corresponding related description of the above embodiments, and details are not repeated herein.

S63, based on the current position information, updating the positioning information domain, and obtaining the IPv6 address of the updated positioning information domain.

Specifically, the step S63 may include:

and S631, coding the current position information according to a preset coding rule to obtain coding information corresponding to the positioning information domain.

The preset encoding rule is a preset rule for encoding the physical position and the logical position. The encoding rule for the physical location information may be in various ways, for example, the abscissa and the ordinate are determined in advance in the area range, the abscissa is written in the first half of the physical location information field in the IPv6 address, and the ordinate is written in the second half of the physical location information field, so as to represent the physical location of the power internet of things terminal.

The logical position information field is 4bits in length and has an initial value of 0000. Wherein the first two bits are the logic position information type, and the last two bits are the logic position information value. The first two logical position information type is 01, which represents that the logical position information type is the inner side and the outer side, and the first two logical position information type is 10, which represents that the logical position information type is the cable phase. When the current two-bit logic position information type is 01, the last two-bit logic position information value is 01 to represent the inner side, and 10 to represent the outer side. When the current two-bit logic position information type is 10, the last two-bit logic position information value is 01 to represent an A-phase cable, 10 represents a B-phase cable, and 11 represents a C-phase cable. For example, if the logical location information field in the IPv6 address specifying the transformer state sensing device in the power internet of things is 0101, it indicates that the logical location of the transformer state sensing device corresponds to the inside of the transformer. When the logical position information field in the IPv6 address of the cable state detection device specified in the power internet of things is 1011, the cable state detection device is located on the C phase of the power transmission cable.

The encoding rule of the positioning information domain is not specifically limited, as long as the positioning information of the power internet of things and the network address identifier can be borne through the IPv6 address, and the encoding rule can be determined according to actual requirements. A specific example is explained here, and it is assumed that the IPv6 address of the terminal of the power internet of things is: AD80:0000:0000:0000: 0064:0025:0101, wherein '0064: 0025' is physical position information, and the physical position information indicates that the current position of the power internet of things terminal is 64 meters on the abscissa and 25 meters on the ordinate; "0101" is logical location information, and the logical location information indicates that the power internet of things terminal is located inside the power equipment.

And S632, updating the positioning information of the positioning information domain based on the coding information to obtain the IPv6 address after the positioning information is updated.

After the coded information corresponding to the positioning information domain is obtained, the edge Internet of things agent equipment updates the physical position information domain in the positioning information domain by the coded value of the physical position information determined by the edge Internet of things agent equipment, and updates the logic position information domain in the positioning information domain by the coded value of the logic position information. After the physical location information domain and the logical location information domain are updated, the IPv6 address of the location information domain after being updated can be obtained, and the IPv6 address is an IPv6 identifier used for representing uniqueness of the power internet of things terminal.

Optionally, the foregoing steps may further include: and in response to the modification operation on the positioning information field, determining the coding information corresponding to the modification operation.

For the logic position information which cannot be sensed through a positioning method, the logic position information of the electric power internet of things terminal stored in the edge internet of things agent equipment can be updated in a periodic manual inspection mode. The edge agent device may then respond to a manual modification operation to the logical location field and determine encoded information corresponding to the modification operation. When the logic position information is changed, the edge internet of things proxy equipment can update the IPv6 address of the power internet of things terminal according to the new logic position information.

In order to verify whether the positioning information of the positioning domain is correct, the accuracy of the positioning information domain can be verified in a regular manual inspection mode. When the coded information in the positioning information domain is found to be wrong, the patrol personnel can modify and correct the coded information, at the moment, the edge internet of things agent equipment can respond to the modification operation of the patrol personnel on the positioning information domain, determine the coded information corresponding to the modification operation, and update the IPv6 address of the power internet of things terminal according to the new positioning information.

Whether the coding information of the positioning information domain is accurate is determined by combining a manual inspection mode, and when the coding information of the positioning information domain is wrong, the manual modification operation on the positioning information domain can be responded, and the coding information corresponding to the modification operation is determined. Therefore, the accuracy of the coded information is guaranteed, and accurate position updating of the power internet of things terminal is further guaranteed.

S64, based on IPv6 address of updated location information domain, packaging downlink communication data packet, and sending the downlink communication data packet to target access node. For detailed description, reference is made to the corresponding related description of the above embodiments, and details are not repeated herein. The method for determining the target access node comprises the following steps:

(1) and calculating the distance between at least one access node and the power Internet of things terminal based on the information parameters.

Given the position of each access node, the edge internet of things proxy device can calculate the distance between each access node and the power internet of things terminal according to the signal parameters about the same power internet of things terminal and the position of each access node, which are sent by each access node.

(2) And comparing the distances between the access nodes and the electric power Internet of things terminal, and determining the access node closest to the electric power Internet of things terminal.

And the edge Internet of things agent equipment compares the distances between each access node and the power Internet of things terminal, and determines the access node closest to the power Internet of things terminal.

(3) And determining the access node closest to the power Internet of things terminal as a target access node.

The edge Internet of things agent equipment takes an access node closest to the electric power Internet of things terminal as a target access node, and transmits the downlink communication data packet to the electric power Internet of things terminal through the target access node, so that the transmission time of the downlink communication data packet is reduced, the communication efficiency is improved, the positioning updating efficiency of the electric power Internet of things terminal is improved, and the real-time performance of positioning updating is ensured to the greatest extent.

By comparing the distances between the access nodes and the electric power Internet of things terminal, the access node closest to the electric power Internet of things terminal is used as the target access node, so that the transmission time of communication data packets can be reduced, and the real-time performance of position updating of the electric power Internet of things terminal is guaranteed to the greatest extent.

Optionally, the method may further include: when the positioning information of the positioning information domain is updated, the positioning updating request information corresponding to the positioning updating request domain is recovered.

When the edge internet of things agent device has processed the location update request initiated by the power internet of things terminal, the location update request information in the location update request field may be restored to a default value, for example, 0, so as to avoid subsequent repeated triggering of location update of the power internet of things terminal. And meanwhile, updating the IPv6 address of the power material network terminal by the coding information of the current positioning updating request field and the current positioning information field.

According to the positioning method of the power internet of things terminal provided by the embodiment, the current position information is coded according to the preset coding rule, and the positioning information of the positioning information domain is updated according to the coded information, so that the position of the power internet of things terminal is updated through the IPv6 address. After the positioning update is started, the subsequent repeated triggering of the position update of the terminal of the electric power internet of things is avoided by recovering the positioning update request information corresponding to the positioning update request domain.
