The communication networking method comprises the following steps: after receiving beacon frames sent by a plurality of main node devices, sending attachment application information to the plurality of main node devices; after receiving the attachment confirmation information sent by at least one main node device in the plurality of main node devices aiming at the attachment application information, sending link application information to the main node device with the largest signal field intensity in the at least one main node device; receiving link confirmation information sent by the main node equipment with the largest signal field intensity in the at least one main node equipment aiming at the link application information; the sub-node equipment is in communication connection with the data acquisition terminal and the main node equipment respectively. By the method, the purpose of improving networking efficiency and the communication reliability of the network after networking is achieved.
Fig. 1 illustrates an implementation flow of a communication networking method provided by an embodiment of the present invention, and for convenience of description, only a part related to the embodiment of the present invention is illustrated, and the following details are described:
the communication networking method in the embodiment of the invention is applied to the child node equipment. As shown in fig. 1, a communication networking method includes:
step 101, after receiving beacon frames sent by a plurality of main node devices, sending attachment application information to the plurality of main node devices;
102, after receiving attachment confirmation information sent by at least one main node device of the plurality of main node devices for the attachment application information, sending link application information to a main node device with the largest signal field intensity in the at least one main node device;
103, receiving link confirmation information sent by the master node equipment with the largest signal field intensity in the at least one master node equipment aiming at the link application information; the sub-node equipment is in communication connection with the data acquisition terminal and the main node equipment respectively.
In a telecommunication communication network, a node is a connection point, representing a redistribution point or a communication terminal (terminal devices). A physical network node is an active electronic device connected to a network and capable of sending, receiving or forwarding messages over a communication channel. In data communications, a physical network node may be a data circuit termination device, such as a modem, hub, bridge, or switch; or it may be a data terminal device such as a digital handset, printer or host (e.g. router, workstation or server). The child node devices and the master node devices in the embodiments of the present invention are some node devices in the data communication system. In addition, the child node device and the master node device are only used to distinguish different node devices, and the child node device and the master node device are relative terms and do not constitute a limitation on the node devices.
In the process of communication networking, the main node equipment sends beacon frames to the sub-node equipment, and the sub-node equipment sequentially and circularly waits for the beacon frames sent by the main nodes at a plurality of different frequency points. Therefore, the sub-node device may receive the beacon frames sent by the plurality of main node devices at the plurality of frequency points. The child node devices can receive the beacon frame sent by a certain main node device, and the possibility that communication can be achieved between the child node devices and the main node device is shown. The beacon frame can realize the synchronization function of the coordination point and the surrounding node equipment, and meanwhile, the node equipment can identify each network through the beacon frame. In the embodiment of the invention, the beacon frame can realize the synchronization function of the main node equipment and the sub-node equipment.
After receiving the beacon frames sent by the multiple main nodes, the sub-node equipment sends attachment application information to the main node equipment which receives the beacon frames, and the sub-node equipment tries to perform networking communication with the main node equipment. The attach application information includes a request for an attach application. Assuming that the child node device receives beacon frames sent by 5 master node devices (respectively, master node device a, master node device B, master node device C, master node device D, and master node device E), the child node device sends attachment application information to the 5 master node devices.
For the attach application information, all or part of the master node devices may respond, that is, all or part of the master node devices transmit the attach acknowledgement information transmitted for the attach application information to the child node devices, and part of the master node devices may not respond, that is, may not transmit the attach acknowledgement information for the attach application information transmitted by the child node devices. If the master node equipment does not respond correspondingly, the master node equipment and the sub-node equipment which do not respond do not have the possibility of networking communication; if the main node device responds, it is described that there is a possibility that communication is possible between the main node device and the child node device.
Therefore, the child node device may receive the attachment confirmation information sent by all the master node devices in the plurality of master node devices; or the child node device only receives the attachment confirmation information sent by a part of the master node devices in the plurality of master node devices, and the child node device only has the possibility of networking communication with the master node device sending the attachment confirmation information in the plurality of master node devices after receiving the attachment confirmation information sent by at least one master node device in the plurality of master node devices. Also taking the above 5 master node devices (master node device a, master node device B, master node device C, master node device D, and master node device E) as an example, assuming that the child node device receives the attachment confirmation information sent by master node device B, master node device C, and master node device E, the child node device has a possibility of networking communication with master node device B, master node device C, and master node device E.
After receiving the attachment confirmation information sent by at least one main node device in the plurality of main node devices aiming at the attachment application information, the sub-node devices send link application information to the main node device with the largest signal field intensity in the at least one main node device, and then networking is completed after receiving the link confirmation information sent by the main node device with the largest signal field intensity in the at least one main node device aiming at the link application information.
If only one of the plurality of master node devices transmits the attachment confirmation information for the attachment application information, the child node device transmits the link application information to the master node device to perform networking communication with the master node device. Similarly, taking the above 5 master node devices as an example, assuming that only the master node device B sends the attachment confirmation information for the attachment application information, the child node devices send the link application information to the master node device B after receiving the attachment confirmation information sent by the master node device B, and then complete networking after receiving the link confirmation information sent by the master node device B for the link application information.
If all the master node devices in the plurality of master node devices send the attachment confirmation information aiming at the attachment application information, and the possibility of networking communication exists between the child node device and the plurality of master node devices sending the attachment confirmation information is described, the child node devices send the link application information to the plurality of master node devices sending the attachment confirmation information.
Also taking the above 5 master node devices as an example, assuming that three master node devices, namely, master node device B, master node device C, and master node device E, have sent attachment confirmation information for the attachment application information, the child node device sends the link application information to the master node device with the largest signal field intensity among master node device B, master node device C, and master node device E after receiving the attachment confirmation information sent by master node device B, master node device C, and master node device E. Assuming that the signal field intensity sequence of the master node device is master node device C, master node device B, and master node device E among master node device B, master node device C, and master node device E, the child node devices transmit link application information to master node device C, and then complete networking after receiving link confirmation information transmitted by master node device C for the link application information.
In the embodiment of the invention, after receiving beacon frames sent by a plurality of main node devices, the method sends attachment application information to the plurality of main node devices; after receiving the attachment confirmation information sent by at least one main node device in the plurality of main node devices aiming at the attachment application information, sending the link application information to the main node device with the largest signal field intensity in the at least one main node device; and receiving link confirmation information sent by the main node equipment with the largest signal field intensity in the at least one main node equipment aiming at the link application information. In the embodiment of the invention, the sub-node equipment can send the link application information to the main node equipment with the maximum signal field intensity for networking after receiving the attachment confirmation information sent by the main node equipment, and networking is completed after the sub-node equipment receives the link confirmation information sent by the main node equipment with the maximum signal field intensity, so that not only can the networking efficiency be improved, but also the communication reliability of the network after networking can be improved.
In an embodiment of the present invention, the child node device is in communication connection with the data acquisition terminal and the master node device through a wired or wireless network, respectively. In an embodiment of the present invention, the child node device and the master node device communicate with each other in a full duplex time division communication manner.
In an embodiment of the present invention, the master node device sends the beacon frame to the child node device in a broadcast packet manner. The broadcast message refers to a message type including a Protocol Data Unit (PDU for short). The protocol data unit includes a broadcast message header, a broadcast message length, and broadcast message data.
In an embodiment of the present invention, the information in the beacon frame includes one or more of the following: beacon frame identification, time slot number, Network identifier of main node device (English full name: Personal Area Network ID, PANID for short); the method can also comprise the network scale of the network where the main node equipment is located, a network working channel, a network public channel, the random transmission delay of the network and the like.
In an embodiment of the present invention, the transmission time slots of the beacon frames are allocated by combining Time Division Multiple Access (TDMA) with carrier sense multiple Access/Collision Avoidance (CSMA/CA).
In an embodiment of the present invention, the time interval of sending the beacon frame by the master node device in the networking process is a beacon period. The total beacon period is the product of the beacon period and the number of beacon wheels. The number of beacon rounds includes a plurality of beacon rounds, a time interval of sending a beacon frame of each beacon round is a beacon period, and each beacon period includes a plurality of time slots. Namely, the relationship among the total beacon period, the number of beacon wheels, and the time slots can be expressed by the following formula:
Tq=Tb×M,TSUM=Tq×N;
wherein, TbRepresenting time slots, M representing the number of time slots in a beacon period, TqIndicating the beacon period, N indicating the number of beacon rounds, TSUMIndicating the total beacon period.
In an embodiment of the present invention, the link confirmation information includes a child node device short address, and step 103, receiving link confirmation information sent by a master node device with the largest signal field strength in at least one master node device for the link application information, includes:
and receiving the short address of the sub-node equipment sent by the main node equipment with the maximum signal field strength in the at least one main node equipment aiming at the link application information.
After receiving the link application information sent by the child node device, the master node device with the largest signal field intensity sends link confirmation information to the child node device if responding to the link application information sent by the child node device, wherein the link confirmation information contains the child node device short address. The short address of the subnode equipment is used for identifying and distinguishing different subnode equipment and linking the subnode equipment of the main node equipment with the maximum signal field intensity. And the sub-node equipment considers that the networking is successful when receiving the short address of the sub-node equipment sent by the main node equipment with the maximum signal field strength aiming at the link application information in the at least one main node equipment.
