In one embodiment, referring to fig. 3, fig. 3 is a flowchart illustrating an exemplary method for forming a regional communication network, and the networking of step S10 may include the following steps:
s101, each node terminal periodically transmits own positioning information to a control system; the positioning information comprises an ID number of the node terminal and satellite positioning data thereof.
In order to form a dynamic regional communication network, each node terminal can be managed by a control system to carry out networking, and each node terminal sends satellite positioning data (such as a Beidou positioning system and a GPS positioning system) of the node terminal to the control system in a periodic sending mode.
S102, the control system acquires the spatial position of each node terminal according to the positioning information.
The positioning information contains the ID number of the node terminal, and can be bound with the corresponding node terminal; because the positioning information only contains satellite positioning data, and each node terminal is distributed in a three-dimensional space, a space model is utilized to establish a three-dimensional coordinate system (O-xyz coordinate system), a wireless positioning technology is utilized to measure the height, and the satellite positioning data is combined to obtain the space position.
And S103, the control system divides the areas according to the space positions, and networking a plurality of node terminals belonging to one area to form a dynamic area communication network.
The control system divides all node terminals into a plurality of spatial areas according to the spatial positions, as shown in fig. 4, fig. 4 is a networking schematic diagram of an exemplary regional communication network, node terminals belonging to the same spatial area are networking, black dots in the figure represent node terminals, and a networking area is represented in a dashed frame, for example, the node terminals are divided into a network 1, a network 2, a network K … …, and the like, so as to form a dynamic regional communication network.
For the control system networking regional communication network, it is a vital ring to divide the region of each node terminal, in order to realize that the node terminal can perform stable communication with the control system, the application provides an embodiment of dividing the region of the node terminal, according to this, the method for dividing the region of the control system according to the spatial position may include the following steps:

According to the technical scheme, the spatial distribution model and the signal intensity model are firstly constructed, then the regional division adjustment is carried out by utilizing the proportion value of the regional signal intensity value to the total signal intensity value of all the node terminals, and the signal intensity of each region can be kept within a certain range through continuous adjustment, so that more reasonable regional division can be obtained, the node terminals of the regional communication network can be stably communicated with the control system during data transmission, and the communication reliability is ensured.
And S104, the control system sends the networking notification message to the corresponding node terminal in each regional communication network through the control system.

S105, each node terminal determines the affiliated regional communication network according to the received networking notification message.
Each node terminal can determine the local communication network to which the node terminal belongs according to the networking notification message and communicate with the node terminals in the local communication network.
In the solution of the above embodiment, each node terminal is managed by the control system, the calculated spatial position is used to perform networking according to the spatial position to form a dynamic regional communication network, and because the spatial position of the node terminal is changed, the control system needs to divide the spatial region according to the dynamic monitoring condition, so that all the node terminals are always in the optimal networking, thereby optimizing the communication network and improving the communication stability.
S20, when the real-time monitoring data is transmitted, the sending node terminal selects the receiving node terminal from the online node terminals in the regional communication network.
The control system may select an optimal receiving node terminal from the online node terminals in the respective regional communication networks according to a communication state of the online node terminals with the control system directly.
Preferably, when the control system sends the networking notification message, the ID numbers of the node terminals in the regional communication network to which the control system belongs are ordered in the networking notification message, the first order is a default receiving node terminal, and the subsequent node terminals can be backup receiving node terminals.
For the format of the networking notification message, reference may be made to fig. 5, where fig. 5 is a schematic diagram of an exemplary networking notification message structure; as shown in the figure, the control system divides all node terminals into 50 regional communication networks, wherein the network 1 includes node terminals with ID numbers 078, 032, 081, 001, 093, 101, etc., and according to the sequence number, the node terminal 078 can be known as a receiving node terminal, the node terminal 032 is a backup receiving node terminal, and so on; therefore, the sending node terminal can dynamically select the optimal receiving node terminal to send the transmission data, so that the communication efficiency is improved, and the stability is ensured.
S30, the sending node terminal generates an optimal transmission path which is routed to the receiving node terminal, converts the real-time monitoring data of the sending node terminal into transmission data of a custom protocol and sends the transmission data to the receiving node terminal through the optimal transmission path.
In one embodiment, step S30 specifically includes the steps of:
s301, a sending node terminal detects online node terminals in a regional communication network and acquires signal energy values and transmission error rates of all the online node terminals.
As an embodiment, the method for acquiring the signal energy value and the transmission error rate of the on-line node terminal in step S301 may include the following steps:
(a) Each node terminal in the regional communication network regularly broadcasts heartbeat data to other node terminals and receives the heartbeat data broadcast by other node terminals; the heartbeat data comprises an ID number of the node terminal, a signal energy value and a transmission error rate of the signal energy value.
(b) And the sending node terminal detects the online node terminal in the regional communication network according to the received heartbeat data broadcast by other node terminals.
(c) And the sending node terminal determines the signal energy value and the transmission error rate of each online node terminal according to the ID number of the online node terminal.
According to the scheme of the embodiment, through the heartbeat data periodically broadcast by each node terminal in the regional communication network, each node terminal can acquire the online node terminal in the regional communication network, and can acquire the signal energy value and the transmission error rate of each online node terminal, so that surrounding node terminals can be perceived in real time, the mutual communication state is maintained, and even if part of node terminals are disconnected, the situation can be detected in time.
S302, the transmitting node terminal establishes a plurality of transmission paths from the transmitting node terminal to the receiving node terminal according to the online node terminal, and determines the node terminal passing through each transmission path.
S303, the sending node terminal calculates a corresponding comprehensive evaluation value according to the number of node terminals of each transmission path, the signal energy value and the transmission error rate, and selects an optimal transmission path according to the comprehensive evaluation value.
As an example, in calculating the comprehensive evaluation value of the transmission path in step S303, the following calculation formula may be adopted:
α+β+γ＝1
in the above formula, n is the number of node terminals through which a transmission path passes, Q represents a signal energy value of the node terminal, P represents a transmission error rate of the node terminal, M represents a comprehensive evaluation value, subscripts 1-n represent corresponding node terminal numbers, and α, β, γ are set constants.
Preferably, α=0.3, β=0.2, γ=0.5; the value distribution can fully integrate the influence factors such as the number of node terminals, the signal energy value, the transmission error rate and the like, and fully reflect the transmission capacity and the transmission effect of each node terminal.
For example, as shown in fig. 6, fig. 6 is a schematic diagram of an exemplary transmission path, assuming that there are three paths for transmission from a transmitting node terminal a to a receiving node terminal E:
transmission path 1: a, B and E;
transmission path 2: A-E;
transmission path 3: a, C, D and E;
in the selection of the transmission paths, the comprehensive evaluation value calculation formula is utilized to comprehensively evaluate each transmission path, and the obtained comprehensive evaluation value is sequenced as 'transmission path 1', 'transmission path 2', 'transmission path 3'; therefore, after the comprehensive evaluation, although the number of node terminals passing through the "transmission path 2" is minimum, the factors of low signal energy and high transmission error rate are caused by the long distance, so that the comprehensive evaluation value is smaller than the "transmission path 1", and the "transmission path 3" selects the "transmission path 1" for data transmission because the total calculated comprehensive evaluation value is minimum due to the large number of node terminals passing through the "transmission path 3".
According to the technical scheme, when data are transmitted, a plurality of transmission paths are calculated from the online node terminals, and meanwhile, a comprehensive evaluation algorithm based on the number of the node terminals, the signal energy value and the transmission error rate is designed, and the optimal transmission path is selected for transmission, so that all aspects of influence factors of communication transmission can be fully considered, and the transmission path with optimal communication quality is used, and therefore the efficiency and stability of data transmission can be guaranteed.
S304, the sending node terminal converts the real-time monitoring data into transmission data of a self-defined protocol, and forwards the transmission data to the receiving node terminal through the optimal transmission path.
As an embodiment, the method for forwarding transmission data to a receiving node terminal through an optimal transmission path may include the following:
(d) And the sending node terminal generates first transmission data according to the self first real-time monitoring data by a self-defined protocol, and sends the first transmission data to the next node terminal on the optimal transmission path in a point-to-point communication mode.
In one embodiment, referring to fig. 7, fig. 7 is an exemplary flow chart of a peer-to-peer communication scheme, and the peer-to-peer communication scheme in step (d) may include the following:
s1, the sender divides the transmission data into N data packets, and generates a data packet queue.
s2, sending a data transmission request to a receiver, wherein N is more than or equal to 2, and the transmission request comprises the number of data packets and the data quantity.
s3, after receiving the transmission request, the receiving party sends a data transmission confirmation to the sending party.
And s4, after receiving the transmission confirmation, the sender reads the first data packet from the data packet queue and sends the first data packet to the sender.
S6, after receiving the first data packet, the receiving party performs verification on the data packet and replies confirmation to the sending party;
s7, after receiving the acknowledgement, the sender determines whether the N packets in the packet queue are sent out? If yes, the transmission process is completed, otherwise, the step s4 is returned.
The sender refers to a node terminal needing to send data, and the receiver refers to a node terminal needing to receive data.
In the point-to-point communication manner in the above embodiment, the transmission data is formed based on the custom protocol, and for the custom protocol, the custom data format can be embedded based on the bluetooth protocol or the WiFi protocol, so as to form the required transmission protocol; in the transmitting process, through the sub-packet transmission and the packet-by-packet check sum confirmation protocol, when transmission interruption occurs, the standby transmission path can be timely utilized for transmitting, the data integrity can be ensured, the packet loss is avoided, and the communication stability is ensured.
(e) The next node terminal obtains corresponding first real-time monitoring data from the first transmission data sent by all other node terminals according to the self-defined protocol, combines the first real-time monitoring data with the second real-time monitoring data of the next node terminal to obtain second transmission data, and sends the second transmission data to the next node terminal on the optimal transmission path in a point-to-point communication mode.
(f) And so on until the transmission data of each sending node terminal is sent to the receiving node terminal.
For example, taking the above-mentioned "transmission path 3" as an example, that is, in the transmission process of a→c→d→e, the transmitting node terminal a first transmits the first transmission data to the second node terminal C, the second node terminal C generates the second transmission data and transmits it to the third node terminal D, and the third node terminal D generates the third transmission data and transmits it to the receiving node terminal E, thereby completing the forwarding process on the transmission path.
According to the technical scheme, when the transmission data is transmitted, the transmission node terminal generates the transmission data by the real-time monitoring data of the transmission node terminal and transmits the transmission data to the next node terminal, the next node terminal receives the transmission data of at least one transmission node terminal, and the transmission data is combined with the real-time monitoring data generated by the transmission node terminal to form new transmission data and then transmitted to the next node terminal, and the real-time monitoring data is transmitted to the receiving node terminal with optimal communication quality to the control system through the gradual transmission mode.
In general, at least one receiving node terminal is set in an area communication network, and when a certain number of receiving node terminals are reached in the area communication network, a plurality of receiving node terminals can be set, so that the receiving node terminals in the area communication network can always maintain an optimal communication state with a control system, and the communication efficiency and the communication stability are ensured.
And S40, the receiving node terminal forwards the transmission data sent by each sending node terminal in the regional communication network to a control system.
In one embodiment, in the process that the receiving node terminal forwards the transmission data to the control system in step S40, a backup transmission scheme of the transmission data may be further included, which may specifically include the following steps:
(1) Each receiving node terminal selects one receiving node terminal from the adjacent regional communication network as a backup forwarding terminal.
The control system may select a receiving node terminal of one regional communication network from among the regional communication networks according to the regional communication networks adjacent to each regional communication network as the backup forwarding terminal.
Preferably, referring to fig. 8, fig. 8 is a schematic diagram illustrating an exemplary backup transmission scheme, where when issuing a networking notification message, the control system may add a backup area communication network to the networking notification message, and in the networking notification message structure shown in fig. 5, the backup area communication network of "network 1" may select "network 2", so that, when a backup forwarding terminal needs to be used, the receiving node terminal 078 of "network 1" may select the receiving node terminal 002 of "network 2" as the backup forwarding terminal.
(2) And in the process that the receiving node terminal forwards the transmission data to the control system, if a communication link with the control system is broken, forwarding the transmission data to be sent to the backup forwarding terminal.
As in the example described above, the receiving node terminal 078 of the "network 1" can forward the transmission data to the receiving node terminal 002 of the "network 2" to the control system, and since the transmission data is divided into N packets, the transmission of the packets starts from the communication link disconnection position.
(3) And the backup forwarding terminal combines the received transmission data with the transmission data which needs to be sent by the backup forwarding terminal and then sends the combined transmission data to the control system.
As in the previous embodiment, the receiving node terminal 002 of the "network 2" combines the data to be transmitted and transmits the combined data to the control system.
According to the technical scheme, the backup forwarding terminal is arranged for the receiving node terminal, so that when a communication link is broken, transmission data can be forwarded to the control system through the adjacent regional communication network in time, the redundancy effect is realized, and the communication stability is ensured.
In another embodiment, referring to fig. 9, fig. 9 is a schematic diagram of another exemplary backup transmission scheme, where the backup transmission scheme may further include the following:
when a communication link between a default receiving node terminal and a control system is disconnected, selecting a backup receiving node terminal to receive transmission data of each node terminal in the regional communication network to which the receiving node terminal belongs; the backup receiving node terminal sends the transmission data to the control system or to the next receiving node terminal.
For example, in the "network 1" shown in fig. 5, when the communication link between the node terminal 078 and the control system is disconnected, the backup receiving node terminal 032 is selected to receive the transmission data in the regional communication network and forward to the control system, such as a new communication link (1) in the figure, or to the node terminal 002 and forward to the control system, such as a new communication link (2) in the figure.
According to the scheme of the embodiment, when the communication link of the receiving node terminal is disconnected, the backup receiving node terminal in the affiliated regional communication network can be started in time to send transmission data, so that the communication stability can be ensured.
