Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
As shown in fig. 1, an embodiment of the present invention provides an IPv 6-based data transmission system 100, which is applied to a power consumption data collection network. The data transmission system 100 includes a gateway node 110, a routing node 130, and a collection node 150, and the electricity consumption data collection network includes a multi-level sub-network.
Further, in this embodiment, one routing node 130 and a plurality of collection nodes 150 correspond to any one of the multi-level sub-networks. The multiple sub-networks may be arranged according to the distance from the gateway node 110, and pass through the routing nodes 130 in each sub-network to realize data transmission between the adjacent two sub-networks and data transmission between the routing nodes 130 and the gateway node 110.
The sub-network with the smaller distance between the routing node 130 and the gateway node 110 in the two adjacent sub-networks is the upper sub-network, and the sub-network with the longer distance between the routing node 130 and the gateway node 110 in the two adjacent sub-networks is the lower sub-network.
In this embodiment, the collection node 150 is configured to collect power consumption data. The routing node 130 is configured to collect the power consumption data and receive the power consumption data sent by each collection node 150 belonging to the same sub-network, perform fusion processing on the collected power consumption data and the received power consumption data to obtain a corresponding data packet, and forward the data packet sequentially through the routing node 130 of the previous sub-network. The gateway node 110 is configured to receive the data packet sent by the routing node 130, and forward the received data packet to the server.
The collection node 150 and the routing node 130 may be communication modules connected to electric meters that need to collect electricity consumption data, and the gateway node 110 may be a gateway connected to the communication modules.
Further, it is considered that if each collection node 150 and each routing node 130 continuously perform fusion processing on the collected power consumption data and then send the power consumption data to the gateway node 110, and forward the power consumption data to the server, the workload of the gateway node 110 and the server is greatly increased, and the efficiency of controlling the power consumption data by the server is reduced. In this embodiment, the gateway node 110 is further configured to forward each reading instruction sent by the server to each corresponding routing node 130. The routing node 130 is further configured to perform fusion processing on the corresponding reading instructions to obtain corresponding instruction packets, and broadcast the corresponding instruction packets to the collection nodes 150 belonging to the same-level sub-network as the routing node 130, so that the collection nodes 150 send the collected power consumption data to the routing nodes 130 belonging to the same-level sub-network according to the received instruction packets.
In order to improve the utilization rate of the data acquisition system, in this embodiment, the gateway node 110 may also be configured to directly establish a communication relationship with the acquisition node 150, so as to directly obtain the power consumption data sent by the acquisition node 150, and forward the power consumption data to the server after performing fusion processing on the power consumption data.
With reference to fig. 2, an embodiment of the present invention further provides an IPv 6-based data transmission method that can be applied to the power consumption data acquisition network. The power consumption data acquisition network includes multiple sub-networks, wherein each sub-network includes a routing node 130 and multiple acquisition nodes 150, and the detailed flow of the data transmission method will be described in detail below with reference to fig. 2.
In step S110, for each collection node 150, the collection node 150 transmits the collected electricity consumption data to the routing nodes 130 belonging to the same-level sub-network.
In this embodiment, considering that the number of the collection nodes 150 is generally large, and most of the collection nodes 150 are difficult to directly transmit the collected electricity consumption data to the gateway node 110 due to the limitation of the communication distance, the routing node 130 needs to be arranged to forward the data collected by the collection nodes 150.
In order to facilitate the management of the collection nodes 150 by the routing node 130, each collection node 150 may transmit the collected power consumption data to the routing node 130 in the preset same-level sub-network.
Step S120, for each routing node 130, the routing node 130 performs fusion processing on the collected power consumption data and the power consumption data sent by each collection node 150 belonging to the same-level sub-network to obtain a corresponding data packet.
In this embodiment, in order to avoid the problem of resource waste caused by separately providing a router to process the power consumption data sent by each collection node 150, a designated communication module connected to the electric meter may be configured as the routing node 130, so as to achieve the purpose of performing fusion processing on the power consumption data corresponding to the electric meter and the power consumption data sent by each collection node 150.
Step S130, for each data packet, the corresponding routing node 130 forwards the data packet sequentially through the routing node 130 of the upper-level sub-network, so as to transmit the data packet to the gateway node 110.
In this embodiment, the gateway node 110 is configured to forward the received data packet to a server, where a sub-network of two adjacent sub-networks, in which the distance between the routing node 130 and the gateway node 110 is smaller, is a sub-network of a previous level. For example, when the power consumption data collection network includes three levels of sub-networks, the routing node 130 of the third level of sub-network may perform fusion processing on the power consumption data collected by the routing node 130 and the power consumption data sent by each collection node 150 of the sub-network to obtain a data packet, and forward the data packet to the server sequentially through the routing node 130 of the second level of sub-network, the routing node 130 of the first level of sub-network, and the gateway node 110.
For the data packet sent by the third-level sub-network, the routing node 130 of the second-level sub-network, the routing node 130 of the first-level sub-network, and the gateway node 110 only perform forwarding processing, and the routing of the second-level sub-network is further configured to perform fusion processing on the power consumption data acquired by the routing node 130 and the power consumption data sent by each acquisition node 150 of the sub-network to obtain a data packet, and forward the data packet to the server sequentially through the routing node 130 of the first-level sub-network and the gateway node 110.
Optionally, the manner of performing the fusion processing on each electricity consumption data through step S120 is not limited, and in this embodiment, in combination with fig. 3, step S120 may include step S121 and step S123.
In step S121, for each routing node 130, the routing node 130 acquires the IP address of the collected power consumption data and the IP address of the power consumption data transmitted by each collection node 150 belonging to the same-level sub-network.
In this embodiment, when the collection nodes 150 send the electricity consumption data, the electricity consumption data is encapsulated by the preset configured IP address to obtain a data packet, and the data packet is sent to the corresponding routing node 130. When receiving the data packet, the routing node 130 analyzes the packet to obtain the corresponding power consumption data and the IP address. The IP address is at the source IP address of the data message and is generated based on the IPv6 protocol.
Step S123, the routing node 130 generates a new IP address according to the acquired IP addresses, and encapsulates the power consumption data collected by the routing node 130 and the power consumption data sent by the collection nodes 150 belonging to the same-level sub-network by using the new IP address to obtain a data packet.
The manner of generating a new IP address according to each IP address is not limited, as long as the corresponding routing node 130 and each collection node 150 can be effectively identified. In the present embodiment, in conjunction with fig. 4, step S123 may include step S123a and step S123 b.
In step S123a, the routing node 130 obtains, according to the acquired IP addresses, the subnet ID of the subnet to which the routing node 130 belongs, the node ID of the routing node 130, and the node IDs of the collection nodes 150 belonging to the same-level subnet as the routing node 130.
In the present embodiment, the subnet IDs of the nodes belonging to the same-level sub-network are the same, that is, the subnet IDs of the routing node 130 and the collection nodes 150 belonging to the same sub-network are the same.
In step S123b, the routing node 130 generates a new IP address based on the number of nodes in the sub-network, the obtained sub-network ID, and the obtained node IDs.
In this embodiment, the manner of generating a new IP address according to the number of nodes, the number of subnets, and the node ID is not limited, and for example, when a primary subnetwork includes one routing node 130 and three collection nodes 150, the primary subnetwork may include 6bytes, which are the subnet ID, the number of nodes, and the node ID corresponding to four nodes of the primary subnetwork, respectively, in combination with fig. 5.
Further, in order to facilitate management and control of each routing node 130 and each collection node 150, in this embodiment, the data transmission method may further include that the server sends a corresponding copy reading instruction to each routing node 130 and each collection node 150, so that each routing node 130 and each collection node 150 send the collected power consumption data according to the instruction, and with reference to fig. 6, before executing step S110, the data transmission method may further include step S140, step S150, and step S160.
In step S140, the gateway node 110 forwards each copy instruction sent by the server to each corresponding routing node 130.
Step S150, for each routing node 130, the routing node 130 performs fusion processing on each corresponding copy-reading instruction to obtain a corresponding instruction packet.
Step S160, the routing node 130 broadcasts the corresponding instruction packet to each collection node 150 belonging to the same level of sub-network as the routing node 130, so that each collection node 150 transmits the collected electricity consumption data to the routing node 130 belonging to the same level of sub-network according to the received instruction packet.
In this embodiment, in order to avoid the problem of data transmission collision caused by directly sending each reading instruction to each collection node 150 and routing node 130, each instruction may be sent to the corresponding routing node 130, so that the routing node 130 performs fusion processing on the corresponding reading instruction to send to each collection node 150. The corresponding routing node 130 may be the routing node 130 corresponding to the electricity data read by the copy instruction or the routing node 130 belonging to the same-level sub-network as the corresponding collection node 150.
Optionally, a specific manner of executing step S140 to send each copy reading instruction to the corresponding routing node 130 is not limited, and in this embodiment, with reference to fig. 7, step S140 may include step S141, step S143, step S145, and step S147.
In step S141, the gateway node 110 forwards each copy instruction sent by the server to the routing node 130 closest to the gateway node 110 in each routing node 130.
In this embodiment, after receiving the reading instruction sent by the server to read each electricity consumption data, the gateway node 110 may obtain a destination IP address of each reading execution, and if the collection node 150 corresponding to the destination IP address is in direct communication connection with the gateway node 110, the reading instruction may be directly sent to the connected collection node 150, and if there are a plurality of connected collection nodes 150, the gateway node 110 may perform fusion processing on each corresponding reading to obtain an instruction packet, and broadcast the instruction packet to each connected collection node 150.
If the node corresponding to the destination IP address is the routing node 130 or the collection node 150 that is not in direct communication connection with the gateway node 110, the copy instruction may be forwarded to the routing node 130 closest to the gateway node 110 (the routing node 130 that directly establishes communication connection with the gateway node 110) in each routing node 130, for example, the routing node 130 may be the routing node 130 of the first-level sub-network in the three-level sub-networks.
Step S143, the routing node 130 obtains the IP address of each reading instruction, and determines whether the corresponding reading instruction is used to read the power consumption data collected by each node in the sub-network to which the routing node 130 belongs according to the subnet ID in the IP address.
In this embodiment, when the routing node 130 receives each copy instruction sent by the gateway node 110, the IP address (destination IP address) of each copy instruction may be obtained to determine whether each copy instruction is used to read the power consumption data collected by each node (including the routing node 130 and each collection node 150 in the same-level sub-network) in the sub-network to which the routing node 130 belongs. If the copy reading instruction is used to read the electricity consumption data collected by the routing node 130 or the collection node 150 of the sub-network, step S145 is executed, and if the copy reading instruction is not used to read the electricity consumption data collected by the routing node 130 or the collection node 150 of the sub-network, step S147 is executed.
Step S145, determining that the copy instruction has been forwarded to the corresponding routing node 130.
In this embodiment, if the copy reading instruction is forwarded to the corresponding routing node 130, the routing node 130 may perform fusion processing on the copy reading instruction and other corresponding copy reading instructions through step S150 to obtain an instruction packet.
In step S147, the routing node 130 sequentially forwards the copy instruction to the routing nodes 130 of the next-level sub-network, so that the copy instruction is forwarded to the corresponding routing nodes 130.
In this embodiment, if the copy reading instruction is not forwarded to the corresponding routing node 130, for example, if the routing node 130 corresponding to the copy reading instruction is the routing node 130 of the third-level sub-network, the routing node 130 of the first-level sub-network performs the determination of step S143, then step S147 is performed to forward the copy reading instruction to the routing node 130 of the second-level sub-network, and after the routing node 130 of the second-level sub-network performs the determination of step S143, step S147 may be performed to forward the copy reading instruction to the routing node 130 of the third-level sub-network.
Optionally, a specific manner of executing step S150 to perform fusion processing on each copy reading instruction is not limited, and in this embodiment, with reference to fig. 8, step S150 may include step S151 and step S153.
In step S151, for each routing node 130, the routing node 130 acquires the IP address of each copy instruction corresponding to the routing node 130.
Step S153, the routing node 130 generates a new IP address according to each acquired IP address, and encapsulates each corresponding copy instruction by the new IP address to obtain an instruction packet.
In this embodiment, a specific implementation manner of generating a new IP address according to the IP address of each copy instruction may refer to the flow of the steps included in step S123, where it should be noted that, when each copy instruction is processed, it is necessary to obtain the destination IP address of each copy instruction, and the generated new IP address is also the destination IP address of the instruction packet.
Optionally, a specific manner of executing step S160 to process the obtained instruction packet is not limited, and in this embodiment, with reference to fig. 9, step S160 may include step S161 and step S163.
In step S161, the routing node 130 broadcasts the corresponding command packet to each of the collection nodes 150 belonging to the same level of sub-network as the routing node 130.
Step S163, for each collection node 150, the collection node 150 acquires the IP address of the instruction packet, and determines whether the IP address includes the node ID of the collection node 150, so that if the determination result is yes, the collection node 150 transmits the collected electricity consumption data to the routing node 130 belonging to the same-level sub-network.
Further, considering that in each flow step of executing the data transmission method, IP addresses of each collection node 150 and each routing node 130 are required to encapsulate the collected power consumption data or encapsulate the data packet, in this embodiment, with reference to fig. 10, before executing step S140, the data transmission method may further include step S170, step S180, and step S190 to configure IP addresses of each collection node 150 and each routing node 130.
Step S170, for each routing node 130, the routing node 130 obtains the global routing prefix of the gateway node 110, the electric meter address of the routing node 130, and the electric meter addresses of the collection nodes 150 belonging to the same-level sub-network.
In this embodiment, the global routing prefix may be a 64-bit global routing prefix obtained when a gateway device corresponding to the gateway node 110 accesses a network. The electric meter address may be composed of an address number and a manufacturer number, which are used for identification when the electric meter corresponding to the routing node 130 and the collection node 150 is shipped from the factory.
Step S180, the routing node 130 obtains the subnet ID and the node ID configured by the gateway node 110 for the routing node 130 through the stateless address allocation method, and obtains the subnet ID and the node ID configured by the routing node 130 for each collection node 150 belonging to the same level of subnet.
In this embodiment, after the gateway obtains the electric meter address of the electric meter corresponding to each routing node 130, the subnet ID and the node ID may be configured for each routing node 130 by a stateless allocation method.
