Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. 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 application.
It should be noted that, in the embodiments of the present invention, the terms "system" and "network" may be used interchangeably, and "terminal device" and "carrier node" may be used interchangeably. The "plurality" means two or more, and in view of this, the "plurality" may also be understood as "at least two" in the embodiments of the present invention. In addition, it should be understood that the terms first, second, etc. in the description of the embodiments of the invention are used for distinguishing between the descriptions and are not intended to indicate or imply relative importance or order to be construed.
Fig. 1 shows a schematic diagram of a power line carrier communication system according to an embodiment of the present invention. The power line carrier communication system is widely applied to scenes such as transformer stations, buildings and the like. It can be seen that the system is mainly composed of one gateway 101 and a plurality of terminal devices 102. The gateway has relatively high data processing capability and is used for sending information to each terminal device and receiving information of the terminal device. Most terminal devices are actuators or collectors, and the data processing capacity is relatively weak.
Due to the limitation of power line communication, the gateway can only realize direct and reliable communication with part of terminal devices in the system. In order to construct a complete communication network, communication links between gateways and part of terminal devices need to be established first, then the terminal devices are used as routing nodes for expansion, and finally all the terminal devices can be accessed to the power line carrier communication network.
Fig. 2 is a flowchart of a networking scheme for power line carrier communications according to an embodiment of the present invention. The specific steps of the scheme are described below with reference to a flow chart.
S1, the gateway node sends a first request; the information comprising the request has a specific identity so that the carrier node can make a decision by means of the identity.
S2, the carrier node successfully receiving the first request establishes connection with the gateway node and accesses the network.
Specifically, the carrier node determines whether the reception is successful according to the specific identifier of the first request. And if the first request is successful, the carrier node successfully receiving the first request establishes connection with the gateway node and accesses the communication network.
S3, the carrier node which has accessed the network sends a second request; the information comprising the request has a specific identification so that carrier nodes not accessing the network can make a decision by means of the identification.
And S4, the carrier node which is not accessed to the network receives the second request, establishes connection with the carrier node which sends the second request, and accesses the network.
Specifically, the carrier node that does not access the network determines whether the information is successfully received according to the specific identifier of the second request sent by the carrier node that accesses the communication network. If the request is successful, the access network is selected, and if the request is unsuccessful, the second requests sent by other carrier nodes are continuously received.
And S5, repeating S3-S4 until all carrier nodes access the network, and finishing networking.
It should be noted that there is only one gateway node, and the number of carrier nodes is greater than two.
Further, a carrier node that is not accessed to the network receives the second request, and establishes a connection with a carrier node that sends the second request, and the access network specifically includes:
when a carrier node which is not accessed to the network receives a second request, the carrier node establishes connection with the carrier node which sends the second request and accesses the network; when the carrier nodes which are not accessed to the network receive more than one second request, one carrier node with the best communication channel quality is selected to establish connection and access the network. The quality of each communication channel can be calculated by parameters such as the strength and attenuation coefficient of the received signal of the node.
Further, the gateway node and the carrier node both have functions of transmitting and receiving signals. The first request and the second request are both access network requests.
Fig. 3 is a schematic diagram showing networking results of the power line carrier communication provided by the embodiment. It can be seen that the system comprises a gateway node and 12 carrier nodes. Wherein, communication connection exists between adjacent nodes. The information interaction method of the system after networking is that the gateway node carries out information interaction with the carrier nodes connected with the gateway node, and each carrier node carries out information interaction with the carrier nodes connected with the carrier nodes. As shown in the figure system, the gateway node G performs information interaction with carrier nodes N31, N32, and N33, the carrier node N31 performs information interaction with carrier nodes N34, N35, and N36, the carrier node N33 performs information 344444444444 interaction with carrier nodes N37 and N38, the carrier node N34 performs information interaction with carrier node N39, the carrier node N35 performs information interaction with carrier nodes N310 and N311, and the carrier node N38 performs information interaction with carrier node N312.
The invention discloses a power line carrier communication system, which comprises a gateway node and a plurality of carrier nodes, wherein a tree structure is formed, and the carrier nodes are accessed into a network through the following steps: the gateway node sending a first request; the carrier node which successfully receives the first request establishes connection with the gateway node and accesses the network; the carrier node which has accessed the network sends a second request; and the carrier node which is not accessed to the network receives the second request, establishes connection with one carrier node which sends the second request and accesses the network.
Specifically, the tree structure is that the gateway node is a first layer, the carrier nodes are dispersed from a second layer to an Nth layer, N is a natural number greater than 2, and each layer is provided with at least one carrier node; each carrier node only has one parent node, and the carrier nodes of the same layer are not connected.
As shown in fig. 3, G is a gateway node, and carrier nodes N31, N32, and N33 are connected to G, respectively, and are second-tier nodes. N34, N35, and N36 are child nodes of N31, N37 and N38 are child nodes of N33, N32 has no child nodes, and N34 to N38 are third-level nodes. At the fourth level, N39 is a child node of N34, N310, N311 are child nodes of N35, and N312 is a child node of N38. It can be seen that, except for the gateway node, each carrier node may have no child node or a child node, and the number of the child nodes may be 1 or multiple. And each child node has only one parent node.
