Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present 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.
Fig. 1 is a schematic flow chart of a networking method provided by the present invention. Referring to fig. 1, the networking method provided by the present invention includes:
and step 130, generating a routing information table based on the determined networking relay units and gateways, and sending the routing information table to a server.
The execution subject of the networking method provided by the invention can be ad hoc network equipment. The ad hoc network device may include a node unit, a relay unit, a gateway unit, and a server.
Optionally, in step 110, the node unit sends networking request information to each relay unit in a broadcast manner, where the networking request information may include the location information and the identity Code (Identification Code) of the node unit. Each relay unit will verify the networking request information and generate a response. And determining the relay unit responding to the networking request message as a target relay unit, namely, the target relay unit receives the networking request message, generates response data information and sends the response data information to the node unit. At this time, the node unit and the target relay unit confirm that networking is possible. All the node units in the ad hoc network device can request the relay unit to form a network in a broadcasting mode.
The determination mode of networking between the node unit and the relay unit can be implemented by performing identity confirmation and data transmission through a handshake protocol or other network protocols.
Alternatively, the node unit may predetermine all relay units capable of establishing communication connection and performing networking in a preset area, and store information of the relay units in a node memory. The node unit may sequence the communication quality of each relay unit every preset time interval in a networking request stage, and send networking request information to the relay unit with the best communication quality.
For example: the current node unit stores the information of 3 relay units, and the relay unit IDs are respectively No. 1, No. 2 and No. 3. And the current node unit sequences the communication quality of the 3 relay units every 1 minute in the networking stage. And if the relay unit with the best communication quality is the relay unit No. 1, the current node unit and the relay unit are networked. In the next time period, the current node unit reorders the communication quality of the relay units, and assuming that the communication quality of the relay unit # 1 is poor or leaves a preset area, the current node unit determines the relay unit with the best communication quality in the current network environment according to the latest communication quality ranking to perform networking, that is, the node unit can switch the networking relay unit in time in the next time period, so as to ensure the efficiency of data transmission.
Optionally, in a case that it is determined that the target relay unit and the node unit can perform networking, the relay unit requests networking from the remaining relay units and gateways, and then it may determine the remaining relay units and the target gateways that are networked with the target relay unit.
The relay unit is a connection device working on a physical layer, is suitable for interconnection of two identical networks or local area network segments with the same connection, and has the main function of expanding the network transmission distance by retransmitting or forwarding a data signal and keeping the same as original data. The relay unit has the function of amplifying and regenerating signals on the line so as to expand the length of a local area network segment.
Optionally, in step 120, in a case that the target gateway determines to perform networking with the target relay unit, the target gateway requests networking from the remaining gateways, and then all the remaining gateways capable of performing networking may be determined.
The gateway is also called an internetwork connector and a protocol converter. The gateway is used for interconnection of two networks with different protocols. The gateway can be used for interconnection of a wide area network and a local area network, and is a computer system or a device serving as a conversion task. A gateway is a translator between two systems that use different communication protocols, data formats or languages, and even completely different architectures. The gateway needs to repackage the received information to accommodate the needs of the destination system. At the same time, the gateway may also provide filtering and security functions.
Alternatively, in step 130, based on the above steps, communication connections may be established between the target relay unit and the rest of the relay units, between the target gateway and the rest of the gateways, and between all the networking-capable relay units and gateways, and a routing information table may be generated and sent to the server.
The networking method provided by the invention can realize dynamic ad hoc network by the networking of the node units and the relay units and the networking among the relay units and the gateway units; the network transmission path is determined based on the generated routing information table, so that the network transmission efficiency is ensured; and by flexibly adding and deleting network nodes, the network quality can be ensured not to be interfered.
In one embodiment, the determining the remaining relay units and the target gateway that are networked with the target relay unit includes:
under the condition that the target relay unit receives the first response data information, determining other relay units and a target gateway which are networked with the target relay unit;
the first response data information is determined based on first networking request information sent by the target relay unit to each relay unit and each gateway.
Optionally, the target relay unit sends the first networking request information to the remaining relay units and the gateways in a broadcast manner, and the first networking request information may include the self ID of the relay unit and the current network information of the relay unit. The current network information includes, for example: relay unit current performance or relay unit load capacity, etc. When the remaining relay units and gateways receive the first networking request information, whether networking is determined can be judged according to the self attribute information and the current network information. Therefore, the rest of the relay units and the target gateway which can be networked can be determined, and the first response data information is generated in the rest of the relay units and the target gateway and is sent to the target relay unit.
The first response data information indicates that the current equipment receives networking request information and determines that networking can be performed. The determination of networking between the relay units and the gateway may be performed by handshaking protocol or other network protocol for identity confirmation and data transfer.
According to the networking method provided by the invention, the target relay unit is determined to be respectively networked with the rest relay units and the target gateway, so that the communication distance can be increased, and the success rate of network transmission can be improved.
In one embodiment, the determining the remaining gateways that are networked with the target gateway includes:
determining other gateways which are networked with the target gateway under the condition that the target gateway receives second response data information;
and the second response data information is determined based on second networking request information sent by the target gateway to each gateway.
Optionally, the target gateway sends a second networking request message to the other gateways in a broadcast manner, where the second request message may include the self ID of the gateway and current network information of the gateway, where the current network information includes, for example, current performance of the gateway or load capacity of the gateway. When the remaining gateways receive the second networking request information, whether networking is determined can be judged according to the self attribute information and the current network information. Thus, the remaining gateways that are capable of networking may be determined. And the rest gateways send the generated second response data information to the target relay unit.
And the second response data information indicates that the current equipment receives networking request information and determines that networking can be carried out. The networking determination among the gateways can be performed by a handshake protocol or other network protocols to perform identity confirmation and data transmission.
The networking method provided by the invention can increase communication paths and improve the success rate of network transmission by determining the networking of the target gateway and other gateways.
In one embodiment, the networking method further includes:
determining an optimal transmission network path based on the routing information table and the network state information;
wherein the network status information comprises at least one of: the number of channels of the current network, the channel strength, the channel interference, and the devices through which the channels pass.
Optionally, after networking is completed, when the server sends data to the node unit, the data is first sent to the gateway, and the gateway searches for an optimal transmission network path through the established routing table. The gateway and the relay unit with the best network channel quality in the current network topology structure can be calculated through the channel number, the channel strength, the channel interference and the equipment passed by the channel of the current network, and then the corresponding node unit is found, so that the optimal transmission network path is determined for data transmission; or the shortest transmission path from the server to the node unit may be determined as the optimal transmission network path.
Optionally, all the node units may send networking requests in real time, and perform ad hoc networking with the relay nodes and the gateways, so that the routing information table may be updated in real time or periodically according to the current network state, so as to dynamically manage the network path quality of different paths.
The networking method provided by the invention determines the optimal network transmission path through the routing information table and the network state information, thereby effectively ensuring the transmission quality of the communication path and improving the network transmission efficiency.
In one embodiment, the server and each gateway communicate via a 4G network and/or a beidou short message.
Optionally, the node units and the relay units in the network perform ad hoc networking, and communication routing data is reserved between the relay units and between the gateways. When uploading data, the gateway evaluates the signals of the current position. If the signal is stable, the 4G mobile network can be directly used for wireless transmission; and when the signal is not good or no signal exists, carrying out wireless transmission by using a Beidou short message form.
The communication process of the Beidou short message is as follows: firstly, a short message sender encrypts a communication application signal containing a receiver ID number and communication contents and then forwards the communication application signal to an inbound through a satellite; after receiving the communication application signal, the ground central station adds the decrypted and encrypted information into the continuously broadcasted outbound broadcast message and broadcasts the message to users through a satellite; the receiver user machine receives the outbound signal, demodulates and decrypts the outbound telegraph text, and completes one-time communication.
According to the networking method provided by the invention, two communication modes of the 4G network and the Beidou short message are provided, so that the uploading efficiency can be ensured; and the plurality of gateways are connected with the server, so that the setting of 4G network transmission modules is reduced, and the deployment cost of the transmission network can be reduced.
In one embodiment, the ad hoc network device can be applied to a train fire monitoring terminal based on an LoRa network. A node unit, a relay unit and a gateway are arranged in each carriage of the train, and a cloud server is arranged. The node unit may be a temperature sensor and a current sensor.
If two trains A and B stop at the platform, when the node unit of a certain carriage in the train A uploads data, the relay unit of the same carriage can carry out self-networking, and when the network condition in the carriage is poor, the relay unit of the same carriage can not carry out self-networking, and the relay unit of other carriages of the train A or the relay unit in the carriage of the train B can carry out self-networking. Or when the gateway of the same carriage fails, the data of the node unit cannot be uploaded, and at the moment, other carriages of the same train or gateways in other trains can be selected for networking. Then there is the following ad hoc process: the node unit issues its own ID by broadcasting. After receiving the information, the relay unit sends response data information to the node unit. The relay unit distributes the own network information in a broadcasting mode, and the relay unit is received by other adjacent relay units and the gateway unit. The remaining relay units and gateway units send reply data messages to them. And all the node units and the relay units confirm each other. Then the gateway releases the self network information through broadcasting, and performs data transmission and reception confirmation with other gateways. After the flow is confirmed, connection is established between the relay unit and the gateway unit and between the gateways, a routing information table is generated in the gateway, and the routing information table is sent to the server.
The networking equipment provided by the embodiment of the invention can ensure the transmission quality of the data of the node unit of the train fire monitoring system through the self-networking of the LoRa network nodes, can select a path with the optimal network quality by the nodes to transmit the data, and can realize dynamic networking. And network nodes can be flexibly added and deleted, so that the network quality is ensured not to be interfered. When the server side sends data to the node unit, the data are sent to the gateway, and the gateway determines the optimal transmission network path through the established routing information table. The gateway and the relay unit with the best network channel quality are determined, and the corresponding node unit is found for transmission, so that the transmission efficiency is ensured. Meanwhile, the setting of 4G network transmission modules is reduced, and the network deployment cost is reduced to a certain extent.
