The purpose of the present embodiment is to provide a kind of communication means based on LORA from group agreement, for solving existing communication Distance present in method is short, power consumption is high, the technical problem without big data management.It is described in detail below it is of the invention based on LORA makes those skilled in the art not need creative work to manage from the principle and embodiment of the communication means for organizing agreement The communication means based on LORA from group agreement of the solution present invention.
Specifically, the embodiment provides a kind of communication means based on LORA from group agreement, as shown in figure 1, Applied to comprising an at least one LORA gateway modules and be connected with the LORA gateway modules by LORA networkings at least one In the LORA networks that individual LORA node modules are formed, it can be realized at a distance using LORA radio communications（18km）, low-power consumption (0.5ma), high sensitivity (- 140db) connect with stable wireless network.The LORA gateway modules 10 are managed collectively each institute LORA node modules 20 are stated, realize big data management, and the Cloud Server, the Cloud Server and institute are reported by 4G networks The real-time, interactive of LORA gateway modules 10 is stated, so the communication means for organizing agreement certainly based on LORA in the present embodiment can be according to industry Business user-defined flow self-organized network communication agreement, realizes big data management, greatly reduces traditional 3G/4G and directly uses and produce Campus network.
Wherein, each described LORA gateway module and each described LORA node module include：Processor and institute State the connected LORA communication units of processor and be connected with the processor by the data of the LORA communication units send to The 4G communication units of one Cloud Server；The processor, which includes operation, has LORA to organize agreement certainly.
In the present embodiment, the processor is connected with the LORA communication units by SPI interface；The processor with The 4G communication units are connected by UART interface.
The processor is, for example, MCU, and the LORA communication units include LORA chips.
As shown in Fig. 2 described included based on LORA from the communication means for organizing agreement：
Step S1, obtain the device id of the LORA gateway modules or the LORA node modules.
Step S1, determine that it is LORA gateway modules or LORA node modules to carry out current block according to the device id. If LORA node modules, then step S3 is performed, establish the connection with LORA gateways and the number issued according to the LORA gateways According to setting LORA communication behaviors；If LORA gateway modules, then step S4 is performed, receives and handles the data of LORA nodes.
I.e. in the present embodiment, by reading device id, it is known that the specific device type of current application operation, according to equipment Type, into corresponding equipment flowsheet.If node ID, into node processing flow, if gateway ID, into gateway Manage flow.
In the present embodiment, the foundation and the connection of LORA gateways and the data setting issued according to the LORA gateways LORA communication behaviors specifically include：Initialize the lora protocol stacks of node, the lora protocol parameters of configuration node；Monitor whether to lose Connection is lost, if connection is lost, notifies the LORA gateways；The supplemental characteristic configuration lora communication ginsengs issued according to LORA gateways Number；According to lora state, LORA communication behaviors are set；The LORA communications row according to corresponding to performing the LORA communication behaviors of setting For.
Wherein, the LORA communication behaviors include initiating connecting, disconnect, handle data that LORA gateways issue and Initiate heartbeat.Wherein, the connection request that node is sent, Portable device ID.Network interface card receives the connection request of node, sends connection and rings Answer, carry the ID of gateway.If node receives gateway response, registration connects upper gateway, if not receiving connection response, if Fix the time that time connection request is sent.Node initiates heartbeat connection request, if receiving gateway heartbeat response, node is connection Normally, response is disconnected if do not received, counting disconnects request command and sends the frequency of failure, and it is disconnected to calculate transmission next time Connection request subcommand time is opened, and sets and disconnects the time that request is sent next time, is rung if not receiving connection for a long time Should, then it is assumed that connection is lost.
If the LORA communication behaviors performed without any need, notice floor processor sleep, so as to optimized processor Working time, substantially reduce power consumption, and improve real-time.
In the present embodiment, the data for receiving and handling LORA nodes specifically include：Initialize the lora associations of gateway Stack is discussed, configures the lora protocol parameters of gateway；Whether monitoring LORA nodes lose connection；Number is received from each LORA nodes According to；Handle the data received from each LORA nodes.
In the present embodiment, when monitoring LORA node loss connection, an alert data is generated, and by the report Alert data are sent to the Cloud Server by the 4G communication units.So, the Cloud Server may know that loss connection The LORA nodes.
In the present embodiment, also include GPS positioning unit in the LORA gateway modules and the LORA node modules, For positional information to be sent to the Cloud Server by the 4G communication units.
In the present embodiment, the GPS positioning unit and 4G communication units acquiescence in the LORA node modules For closed mode, when the node monitoring unit monitors to lose connection, the GPS positioning unit starts and believes position Breath is sent to the Cloud Server by the 4G communication units so that the Cloud Server is accurately navigated to described in after off-grid The position of LORA node modules 20.
In summary, it is of the invention to be realized at a distance from the communication means for organizing agreement based on LORA（18km）, low work( Consumption (0.5ma), high sensitivity (- 140db) connect with stable wireless network, can be led to according to the self-defined MANET of operation flow Believe agreement, greatly reduce traditional 3G/4G and directly use and caused campus network.So the present invention effectively overcomes now There is the various shortcoming in technology and have high industrial utilization.
The above-described embodiments merely illustrate the principles and effects of the present invention, not for the limitation present invention.It is any ripe Know the personage of this technology all can carry out modifications and changes under the spirit and scope without prejudice to the present invention to above-described embodiment.Cause This, art includes usual skill complete without departing from disclosed spirit and institute under technological thought such as Into all equivalent modifications or change, should by the present invention claim be covered.
