Fig. 1 shows an implementation flow of a communication networking method according to a first embodiment of the present invention, and for convenience of description, only the relevant parts of the embodiment of the present invention are shown, and the following details are described:
as shown in fig. 1, a communication networking method includes:
102, at least one main node device in a plurality of main node devices sends attachment confirmation information aiming at attachment application information to a sub-node device;
103, after receiving the attachment confirmation information sent by at least one of the master node devices, the child node device sends a link application information to the master node device with the largest signal field strength in the at least one master node device;
104, the main node equipment with the maximum signal field intensity in at least one main node equipment sends link confirmation information aiming at the link application information;
105, receiving link confirmation information sent by the main node equipment with the maximum signal field intensity by the sub-node equipment; 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 receiving 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. That is, at least one of the master node devices sends the attachment confirmation information for the attachment application information to the child node device. 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 master node device B, the master node device C, and the master node device E respectively send the attachment confirmation information for the attachment application information to the child node devices, that is, the child node devices receive the attachment confirmation information sent by the master node device B, the master node device C, and the master node device E, then the child node devices have a possibility of networking communication with the master node device B, the master node device C, and the 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 the link application information to the main node device with the highest signal field intensity in the at least one main node device. And after receiving the link confirmation information 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, the sub-node equipment completes networking.
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 an embodiment of the present invention, a sub-node device sends attachment application information to a plurality of main node devices after receiving beacon frames sent by the plurality of main node devices, at least one main node device of the plurality of main node devices sends attachment confirmation information for the attachment application information to the sub-node device, the sub-node device sends link application information to a main node device with a largest signal field strength among the at least one main node device after receiving the attachment confirmation information sent by the at least one main node device of the plurality of main node devices, the main node device with the largest signal field strength among the at least one main node device sends link confirmation information for the link application information, and the sub-node device receives the link confirmation information sent by the main node device with the largest signal field strength; the sub-node equipment is in communication connection with the data acquisition terminal and the main node equipment respectively. 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 rounds. 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:

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.

in step 203, the child node device receives response information sent by the master node device for the data packet.
A base station, which is a form of radio station in a narrow sense, refers to a radio transceiver station that performs information transfer with a mobile phone terminal through a mobile communication switching center in a certain radio coverage area.
A Contention Access Period (CAP) is located between two beacon frames, any device wants to communicate in the Contention Access Period between two beacon frames, and needs to compete with other devices using a Carrier Sense multiple Access/Collision Avoidance (CSMA/CA) mechanism, and all processing must be completed before the next beacon frame is reached.

The Signal Strength (RSSI) is a Received Signal Strength Indication, and is used to determine the link quality.
In the embodiment of the present invention, the preset signal strength is a preset signal strength, and it is understood by those skilled in the art that the value of the preset signal strength may be preset according to actual needs, for example, the preset signal strength may be preset to be-100 dBm (dBm is decibel milliwatt, which may be taken as a unit of voltage or power), or-110 dBm, or-90 dBm, etc., which is not limited in particular by the embodiment of the present invention.

After the adjustment, in order to determine whether the preset power can meet the power requirement during communication, the communication power between the adjusted child node device and the master node device needs to be tested, that is, the master node device tests the communication power between the master node device and the child node device. And under the condition that the preset power does not meet the expected test power, the adjusted communication power between the child node equipment and the main node equipment cannot meet the actual communication requirement.

The master node device may send a scheme request to one of the child node devices, and may send a Guaranteed Time Slot (GTS) to the other child node device, and may receive scheme data of the other child node device while sending the scheme request or the Guaranteed Time slot to the one child node device.
In the embodiment of the invention, the main node equipment sends a scheme number to the first sub-node equipment; the first sub-node device is a sub-node device corresponding to the short address of the sub-node device, the first sub-node device sends scheme data corresponding to the scheme number, which is received from the data acquisition terminal, to the main node device according to the received scheme number, the main node device sends response information aiming at the scheme data to the first sub-node device after receiving the scheme data sent by the first sub-node device, and the first sub-node device receives the response information aiming at the scheme data sent by the main node device, so that the reliability of network communication after networking can be further improved.
Fig. 6 shows an implementation flow of a communication networking method according to a sixth embodiment of the present invention, and for convenience of description, only the relevant portions of the embodiment of the present invention are shown, and the detailed description is as follows:
in an embodiment of the present invention, in order to further improve networking efficiency and communication reliability of a network after networking, on the basis of the steps shown in fig. 1, as shown in fig. 6, the communication networking method further includes:
in step 604, the master node device uses the most idle channel group in the available channel groups as the channel group of the master node device.
A primary station is a data communication term that refers to a data station that, in a basic mode link control, guarantees the transmission of data to one or more secondary stations upon receipt of a request. There can only be one master station on a data link at a given time. In communication, the primary station is responsible for link control, including replies to secondary stations, organizing transmitted data, and recovering from link errors. The channel refers to a communication channel and is a medium for signal transmission, and the channel group refers to a channel combination composed of a plurality of channels, and the channel combination includes an uplink channel/a downlink channel.
In the networking process, the main node equipment firstly sends a deployment request to the main station to perform cellular deployment, and after receiving the deployment request sent by the main node equipment, the main station sends networking requests to the main node equipment in sequence according to the sequence of the time of the deployment request sent by the main node equipment. The main node equipment receives a networking request sent by the main station, and starts a scanning function to scan an available channel group according to the received networking request. And scanning available channel groups, wherein part of the scanned available channel groups may be busy, part of the scanned available channel groups may be idle, and the master node device takes the most idle channel group in the available channel groups as its own channel group. And when all the main node equipment which sends the deployment request to the main station finds the own channel group, the automatic deployment of the cellular network is completed.
In the embodiment of the invention, the main node equipment sends the deployment request to the main station, the main station sends the networking request to the main node equipment in sequence according to the received deployment request, the main node equipment scans the available channel groups after receiving the networking request sent by the main station, and the main node equipment takes the most idle channel group in the available channel groups as the channel group of the main node equipment, so that the networking efficiency and the communication reliability of the network after networking can be further improved.
The embodiment of the invention also provides a communication system, such as the following embodiments. Because the principle of solving the problem of the communication system is similar to the communication networking method, the implementation of the communication system can refer to the implementation of the method, and repeated details are not repeated.
Fig. 7 shows functional modules of a communication system according to a seventh embodiment of the present invention, and for convenience of description, only the parts related to the embodiment of the present invention are shown, and the details are as follows:
referring to fig. 7, each device or terminal included in the communication system is configured to execute each step in the embodiment corresponding to fig. 1 to 6, and specifically, refer to the description in the embodiments corresponding to fig. 1 to 6 and fig. 1 to 6, which is not repeated herein. The communication system in the embodiment of the present invention is a communication system to which the above-described communication networking method embodiment is applied, and includes a sub-node device 701, a main node device 702, and a data acquisition terminal 703, where the sub-node device 701 is in communication connection with the main node device 702 and the data acquisition terminal 703, respectively.
The working principle of the sub-node device 701 and the main node device 702 in the embodiment of the present invention is consistent with the communication networking method described in the above embodiment, and for details, reference is made to the description of relevant parts of the above embodiment, and details are not described here again.
In an embodiment of the present invention, in order to further improve networking efficiency and communication reliability of a network after networking, on the basis of the structure shown in fig. 7, the communication system further includes a base station. And the base station sends the notification information of the contention access period to the child node equipment. The working principle of the communication system in the embodiment of the present invention specifically refers to fig. 2 and the related description in the corresponding embodiment of fig. 2, and is not repeated here.
In an embodiment of the present invention, in order to further improve networking efficiency and communication reliability of the network after networking, on the basis of the structure shown in fig. 7, the communication system further includes a master station. And the master station sequentially sends networking requests to the master node equipment according to the received deployment requests. The working principle of the communication system in the embodiment of the present invention specifically refers to fig. 6 and the related description in the corresponding embodiment of fig. 6, and is not repeated here.
In one embodiment of the present invention, a communication system includes a plurality of channel groups, each channel group including at least one uplink channel and at least one downlink channel. Further, the communication system may include nine channel groups, each channel group including three channels, where the three channels include two uplink channels and one downlink channel. One of the two uplink channels may be used to implement the communication networking method described in the first embodiment corresponding to fig. 1 and fig. 1, and to implement the communication networking method described in the second embodiment corresponding to fig. 2 and fig. 2. And the other uplink channel can be used for realizing time-sharing communication of common communication services.
The communication system in the embodiment of the invention adopts full duplex time division communication, so that an uplink channel and a downlink channel can be simultaneously carried out, and two uplink channels can also be simultaneously carried out, thereby greatly improving the communication networking efficiency and the communication reliability of the communication system after networking.
In addition, the communication system adopts full duplex time division communication, and the uplink channel and the downlink channel adopt different communication channels. That is, while the master node device receives data transmitted by one child node device, the master node device may also transmit data to another child node device. In order to prevent mutual interference between different sub-node devices, a plurality of sub-node devices communicate with the main node device in a time division communication mode. That is, only one child node device can transmit/receive data to/from the master node device at the same time, but the central node device can simultaneously transmit and receive data at the same time. For example, while one child node device transmits data to the master node device, the master node device may transmit data to another child node device.
For example, the master node device may transmit downlink data to another child node device in the same data frame while transmitting the GTS to the child node device. While the master node device sends data and GTS to another child node device 2, the master node device may receive uplink data of one child node device. And the main node equipment can receive the attachment application information and the link application information from one sub-node equipment and simultaneously receive the uplink data from the other sub-node equipment, and the main node equipment and the link application information do not interfere with each other because of being in different uplink channels.
All the main node equipment and the sub-node equipment in the communication system can support remote configuration management and remote upgrading, and can maintain and repair system problems in real time. In addition, network management software, a remote configuration tool, a remote upgrading tool and the like of a webpage end, a mobile phone end and a desktop version can be provided.
The communication protocol in the communication system is implemented by a layered architecture, and includes, from bottom to top, a Port Physical Layer (PHY Layer for short), a Media Access Control Layer (MAC Layer for short), a Network Layer (NWK Layer for short), an application Layer (APS Layer for short), and the like.
For communication rate/communication power adjustment, referring to the description of the relevant parts of the third and fourth embodiments of the present invention, the main logic processes of communication rate/communication power adjustment are all in the network layer, the PHY layer also participates in rate control, and the NWK layer notifies the MAC layer and then notifies the PHY layer to perform rate/power switching.
The pass through function is mainly used for APS communication, and the APS layers can directly communicate with each other. The forwarding function is mainly used for direct communication between external devices connected with the master station and the child node devices, such as sensors.
The main node device can automatically generate a short address to the sub-node device when receiving the link application information sent by the sub-node device, and the process is mainly completed by the NWK layer.
The APP layer of the main node device informs the APS layer of the sub-node device of newly building a scheme and copying scheme data corresponding to which scheme number, namely, the main node device sends the scheme number to the sub-node device, and the APS layer, the NWK layer and the MAC layer only carry out forwarding operation in the process. After receiving the scheme number sent by the main node device, the APP layer of the sub-node device sends a corresponding response to the APS layer of the sub-node device, and the APS layer sends the response to the NWK layer and then to the MAC layer. After the completion, the main node device sends a guarantee time slot to the sub-node device, and the MAC layer of the sub-node device sends response data (i.e., the scheme data corresponding to the scheme number) to the main node device after receiving the GTS.
When the sub-node device sends important data to the main node device, the sub-node device firstly sends the important data to the APS layer through the APP layer of the sub-node device, and then the APS layer records the active reporting information in a cache for waiting to be sent. The APS layer will detect whether the last data transmission event is successfully transmitted or not at regular time, if the transmission is successful, the APS layer will remove the last data transmission event from the buffer and prepare to transmit the next data transmission event, then it will detect whether the NWK layer can transmit the report or not, if the transmission is not successful, the APS layer will continue to wait, otherwise, the APS layer will call the NWK transmission interface to transmit the active report information to the NWK layer. When detecting that the active report is to be sent, the NWK layer firstly monitors a notification message of the CAP, randomly selects a time slice in the CAP to send out data if the notification message is monitored, otherwise, monitors again, waits for the response of the main node equipment for a period of time after sending out, and repeats the steps until the response of the main node equipment is received if the response of the main node equipment is not received.
