The technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
The identification of the internet of things is a basic supporting technology for realizing accurate interaction between objects. With the promotion of the construction of the electric power internet of things, the number of various terminal devices accessed to the network is increased sharply, and the types are complex and various. The existing power equipment identification systems are various in types and poor in compatibility, and in the power service data transmission process, a data packet encapsulated by an application layer also needs to depend on identification information of a source equipment. With the access of massive terminal equipment of the power internet of things, the identification information data volume of various equipment is huge in the service data transmission process, so that huge operation and maintenance cost and resource occupation are caused, and the transmission efficiency of service data is influenced.
Based on the above problem, an embodiment of the present invention provides a service data transmission system, as shown in fig. 1, where the service data transmission system includes: the device comprises a first device and a second device, wherein the first device is used for obtaining a first IPv6 address corresponding to the first device, a second IPv6 address corresponding to the second device and service data to be transmitted, and the first IPv6 address has content representing device identification information of the first device.

Specifically, in the embodiment of the present invention, the first device and the second device are two power devices in an electric power internet of things, and a specific interaction process between the two devices is shown in an interaction schematic diagram shown in fig. 2. In practical application, the first IPv6 address may be a communication address assigned to the first device by the gateway, where the first device sends the device identification information corresponding to the first device to the network segment where the first device is located, after the gateway adds the IPv6 address to the device identification information according to the device identification information, or an initial IPv6 address applied by the first device to the gateway of the network segment where the first device is located, and after the relevant device identification information corresponding to the first device is added to the initial IPv6 address, the gateway verifies the first IPv6 address corresponding to the first device, and the like, which is not limited by the present invention. The detailed working processes of the first device and the second device refer to the following description of the relevant steps of the method embodiment, and are not described herein.
Through the cooperative cooperation of the above components, the service data transmission system provided by the embodiment of the present invention sets the device identification information of the source device in the corresponding IPv6 address, so that the device identification information in the application layer encapsulation format can be removed when the application layer is encapsulated in the service data network communication process, and the size of the data packet is reduced to optimize the transmission resource occupation in the power internet of things. And after the service data reaches the destination device, the destination device can obtain the device identification information of the source device by analyzing the IPv6 address so as to support the completion of the service and realize the optimization of the communication service bearing, thereby realizing the optimization of the transmission resource occupation in the power internet of things and the efficient support of the service of the power internet of things under the condition of not influencing the service transmission performance and improving the service transmission efficiency of the power internet of things.
An embodiment of the present invention further provides a service data transmission method, where the method is applied to the first device, and as shown in fig. 2, the service data transmission method specifically includes the following steps:
step S101: and acquiring a first IPv6 address corresponding to the first equipment, a second IPv6 address corresponding to the second equipment and the service data to be transmitted.
The first IPv6 address has the content of device identification information for representing the first device. Specifically, after the power equipment applies for registration containing equipment identification information, the power equipment is distributed to a working area of the power equipment for putting in and accessing the network, the equipment applies for distributing an IPv6 address containing the equipment identification information to a gateway of a network segment where the equipment is located for networking communication, then networking is completed, and service data can be transmitted through the network after the power equipment accesses the network.
Step S102: and encapsulating the service data to be transmitted based on the first IPv6 address.
Specifically, in the network communication process of the power internet-of-things device, according to a TCP/IP protocol, service data can reach a target power device through an application layer, a transport layer, a network layer, a data link layer, and a physical layer, wherein the service data sent by the power device needs to be subjected to subsequent transmission after being packaged, and a specific packaging mode can be realized by referring to a packaging format of a packaging data packet in the prior art, which is not described herein any more.
Step S103: and removing the equipment identification information of the application layer in the packaged data packet to obtain the updated data packet.
Specifically, when application data sent by the power equipment is encapsulated in an application layer, the equipment identification information in an application layer encapsulation format is removed, and the size of a data packet is reduced, so that the data volume in the service data transmission process is reduced, and the occupation of transmission resources is optimized.
Step S104: and sending the updated data packet to the second equipment based on the second IPv6 address.
And the second IPv6 address is a destination address of the service transmission data, and the data packet is transmitted by a subsequent transport layer, a network layer, a data link layer and a physical layer based on the address and finally reaches the second device.
Specifically, the first IPv6 address in step S101 is obtained as follows: after the power equipment applies for an IPv6 identifier (the IPv6 identifier has power equipment identifier information) to the gateway and registration is completed, the power equipment is distributed to a working area of the power equipment for putting into a network, then the equipment sends a request for applying for distributing an IPv6 address to the gateway of a network segment in which the equipment is located, and the gateway receives the request and then distributes the IPv6 address to the equipment for networking communication; then the equipment sends the IPv6 identification of the equipment to the gateway, after the gateway receives the IPv6 identification, the gateway sends a query confirmation request to the identification management system so as to check whether the identification code exists, and if so, the identification management system returns confirmation information to the gateway; after receiving the confirmation information, the gateway distributes the IPv6 address with the same identification as the IPv6 to the equipment, and finally the equipment carries out network address replacement to complete the network access process.
Specifically, in another alternative embodiment, the step S101 includes the following steps:
and step 21, acquiring an original IPV6 address and equipment identification information of the network equipment.
The device identification information at least comprises mechanism information, service information, device category information and device attribute information.
It should be noted that, when the service data transmission method provided in the embodiment of the present application is applied to an electric power internet of things system, the affiliated entity information may refer to information of an electric power system or a sub-company to which the network device belongs; the service information may refer to the role of the network device in the power system, such as communication, power transmission, voltage transformation, etc.; the device type information may refer to a specific device name of the network device, such as a switch, a transformer, a distributor, and the like; the device attribute information may include information such as the manufacturer and the production number of the network device.
Step 22, converting the equipment identification information into a corresponding IPV6 identification code according to a preset coding specification;
specifically, the device identification information is converted into an IPV6 identification code that can be encapsulated to an IPV6 address. In order to ensure the safety of the equipment identification information and the legality of the IPV6 identification code, the adopted coding specification needs to play a role in encrypting the equipment identification information, and the total digit, the format and the like of the obtained IPV6 identification code are ensured to be in accordance with the standards of the IPV6 address. The specific coding specification may be set according to an actual application scenario, and the embodiment of the present application is not limited.
And step 23, adding the IPV6 identifier code to the original IPV6 address to obtain a corresponding IPV6 identifier address.
It should be noted that, the IPV6 address has 128 bits length, which is advantageous in that the available space of the address is expanded, and the IPV6 address itself has the function of storing the network identification information. The embodiment of the application further makes full use of the available space of the IPV6 address, and encapsulates the IPV6 identification code corresponding to the equipment identification information into the original IPV6 address. Specifically, the packaging of the IPV6 identification code can be realized by directly adding the IPV6 identification code to the tail storage unit.
On the basis of the foregoing embodiment, in order to further ensure the security of the device identification information, as an implementable manner, in an embodiment, according to a preset encoding specification, the converting the device identification information into a corresponding IPV6 identification code includes:
step 2021, converting the affiliated organization information, the service information, the device type information, and the device attribute information into corresponding binary codes, respectively.
Step 2022, converting the binary code into the IPV6 identifier with a preset number of bits using a preset hash function.
It should be noted that the corresponding relationship between the binary code and the various types of device identification information may be established in advance. The binary code bit number corresponding to each type of device identification information may be set according to factors such as system scale.
Specifically, after binary codes corresponding to various types of device identification information are determined, since the total number of bits of the obtained binary codes may exceed the remaining space of the IPV6 address, in order to ensure that the subsequent packaging operation can be completed normally, a hash function may be used to convert the binary codes into IPV6 identification codes of a fixed number of bits (preset number of bits). Moreover, the hash function has the encryption capability, so that the obtained IPV6 identification code belongs to the encrypted equipment identification information, and even if a malicious attacker reads the IPV6 identification code, the malicious attacker cannot read the corresponding equipment identification information.
The hash function may be a one-way mapping hash function. If other mapping functions also have the above capabilities, the hash function may be replaced with other mapping functions.
Specifically, in an embodiment, a coding system identifier corresponding to a binary code may be obtained; and converting the binary coding and coding system identification into an IPV6 identification code with a preset digit number by using a preset hash function.
It should be noted that, under the condition of a large system scale or frequent system update, in order to avoid the problems of deviation and the like in the subsequent device identification information reading process, multiple coding systems can be established. The coding system can determine whether each type of equipment identification information corresponds to binary coding, decimal coding or hexadecimal coding, and can also determine information such as coding digits and the like so as to assist subsequent equipment identification information reading work.
Exemplarily, if the current coding system identifier is 001, the binary code corresponds to the current coding system identifier, and the binary code corresponding to the affiliated mechanism information is 7 bits and is used for identifying the network device affiliation unit; the binary code corresponding to the service information is 4 bits and is used for distinguishing network equipment generated by different service applications; the binary code corresponding to the equipment category information is 20 bits and is used for distinguishing different types of equipment; the binary code corresponding to the device attribute information has 60 bits and is compiled based on the device fixed information. A total of 94 bits of code are obtained and then the 94 bits of code are compressed into a 64 bit IPV6 identification code based on the method provided by the above embodiment.
Further, in one embodiment, the IPV6 identification code may be stored to a database.
In particular, the IPV6 identification code may be stored to the database in association with the IP address of the network device.
Further, acquiring an equipment identification information reading instruction input by a user; reading an instruction according to the equipment identification information, and extracting a corresponding IPV6 identification code from a database; and analyzing the IPV6 identification code to obtain corresponding equipment identification information.
If the IPV6 identification code in the database is stored in association with the IP address of the network device, the device identification information reading instruction input by the user includes the IP address of the target object (target electrical device).
Specifically, an IPV6 identification code of the target object is extracted from the database, and corresponding equipment identification information is restored according to the IPV6 identification code for a user to read.
Specifically, in one embodiment, the IPV6 identification address may be registered to bind the IPV6 identification address with the network device.
Specifically, the IPV6 identification address encapsulated with the device identification information is registered in a registration center, so as to ensure that the IPV6 identification address can normally provide services such as communication for the network device.
Illustratively, the participant device identifier manager in the IPV6 identifier address registration process may initiate a registration application in a unified manner, and complete the binding between the network device and the IPV6 identifier address. After the identification management service platform receives an identification information analysis service application (an equipment identification information reading instruction) of a user to the network equipment, the equipment identification information manager analyzes and reads the equipment identification information from the database by using the identification analysis server according to the IPv6 identification code and feeds the equipment identification information back to the user.
In particular, in an embodiment, the IPV6 identification code may be added to the interface identification field of the original IPV6 address.
It should be noted that the storage unit of the IPv6 address is generally divided into 6 domains, which are a network prefix domain, a network platform domain, a network device/service VPN domain, an organization domain, a sub-network domain, and an interface identification domain.
Specifically, the first 64 bits (bit) of the IPV6 address are allocated and assigned with the network information of the network device according to the IPV6 address allocation requirement, and the second 64 bits are an interface identification field and can be used to store the IPV6 identification code corresponding to the device identification information.
By executing the above steps, the service data transmission method provided in the embodiment of the present invention sets the device identification information of the source device in the corresponding IPv6 address, so that when the application layer is encapsulated in the service data network communication process, the device identification information in the application layer encapsulation format can be removed, the size of the data packet is reduced, the optimization of the transmission resource occupation in the power internet of things is realized, and the service transmission efficiency of the power internet of things is improved.
An embodiment of the present invention further provides a service data transmission method, where the method is applied to the second device, and as shown in fig. 2, the service data transmission method specifically includes the following steps:
step S201: and receiving a data packet which is sent by the first equipment and contains service data to be transmitted.
Wherein the application layer of the data packet does not contain the device identification information.
Step S202: and analyzing the data packet to obtain service data to be transmitted and a first IPv6 address corresponding to the first equipment.
The first IPv6 address has the content of device identification information for representing the first device. The IPv6 address identification attribute of the network layer is given, the IPv6 partial address bit without information quantity is given with the equipment identification information, the identification information has the same effect with the identification information of the previous application layer, the identification function requirement in the equipment communication process can be supported, the resources are multiplexed, the remaining space is used for transmitting more application data, and the optimization of the communication service mechanism is realized.
Step S203: and analyzing the first IPv6 address to obtain equipment identification information corresponding to the first equipment.
Specifically, since the first IPv6 address includes content having device identification information representing the first device, the identification information of the service data sending device may be obtained by analyzing the first IPv6 address, and then the identification information is used to support completion of a service between two devices.
By executing the above steps, the service data transmission method provided in the embodiment of the present invention sets the device identification information of the source device in the corresponding IPv6 address, and after the service data reaches the destination device, the destination device can obtain the device identification information of the source device by analyzing the IPv6 address, so as to complete the service support and optimize the service bearer, thereby implementing optimization of transmission resource occupation in the power internet of things and efficient support of the service of the power internet of things without affecting the service transmission performance, and improving the service transmission efficiency of the power internet of things.
The service data transmission method provided in the embodiment of the present invention will be described in an entirety.
After the power equipment applies for the IPv6 identifier (the IPv6 identifier has the related identifier information of the power equipment) to register, the power equipment is distributed to a working area of the power equipment to be launched into a network, the equipment applies for distributing an IPv6 address which is the same as the IPv6 identifier to a gateway of a network segment where the equipment is located for networking communication, and then network access is completed; in the network communication process of the power Internet of things equipment, application data are packaged when being transmitted to each layer, a header part in a data packet packaged by an application layer contains identification information of the equipment, and the identification content is removed from the application layer header; based on the IPv6 identifier, the IPv6 address identifier attribute of the network layer is given, the IPv6 address bit of the occupied transmission resource is the IPv6 address bit, the header part of the network layer data packet is given with the equipment identifier information by the IPv6 address bit without information content, the identifier function requirement in the equipment communication process can be supported, and the mechanism of communication service bearing optimization is realized. The invention provides an equipment network access method based on an IPv6 identifier, which ensures the practicability of the equipment identifier, and simultaneously provides a communication service bearing method in the power Internet of things, so that the optimization of transmission resource occupation in the power Internet of things and the efficient support of the service of the power Internet of things are realized.
In the electric power thing networking, if two equipment carry out network communication, application data all can encapsulate when transmitting each layer, when conveying the data link layer, can be encapsulated into the form of data packet. In the network communication process, the header part of the application layer encapsulation contains the identification information of the device, including the identity identification information and static attribute information of the device. The IPv6 identifier contains the information, and the IPv6 address bit of the occupied transmission resource is the IPv6 address bit, which is the packet head part of the network layer, endows the IPv6 address bit without information quantity with the equipment identifier information, and can support the identifier function requirement in the equipment communication process. Because the equipment identification content in the application layer data packet is redundant and repeated with the identity information and the static attribute in the IPv6 address, and the equipment identification function can be completed, the equipment identification content in the application layer can be omitted, the whole size of the data packet is reduced, and the optimization of the occupation of transmission resources in the power Internet of things is realized.
