Referring to fig. 2, fig. 2 is a schematic flowchart of a LoRa communication method according to a first embodiment of the present application.
While the present embodiments provide an embodiment of the LoRa communication method, it should be noted that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in an order different from that here.
The LoRa communication method is used for an edge server, the edge server is connected with at least two transmitting terminals, wherein each transmitting terminal corresponds to at least two channels, and the method comprises the following steps:
step S10, when the operation instruction sending condition is satisfied, the target transmitting terminal and the target channel are determined;
in this embodiment, a Multiple-Input Multiple-Output (MIMO) technique is used for a multipath wireless channel, and it refers to using Multiple transmitting antennas and Multiple receiving antennas at a transmitting end and a receiving end respectively, and is different from a conventional signal processing method in that it simultaneously studies signal processing problems from two aspects of time and space, so as to improve a data rate of a system, reduce a bit error rate, and improve transmission quality of a wireless signal without increasing a bandwidth and a transmission power. The application applies the MIMO technology to Long-distance radio communication (Long Range, LoRa for short), and the biggest characteristic of the LoRa communication is that the distance of propagation is farther than that of other wireless modes under the same power consumption condition, so that the low power consumption and the Long distance are unified. In the prior art, the LoRa communication implements one-to-one communication, that is, a receiving end and a transmitting end are used for communication, because this communication method has only one channel, when the channel fails, the communication cannot be performed, and at the same time, the information that can be transmitted by one channel is limited, which results in low and unstable transmission efficiency. When the MIMO technology is applied to the LoRa communication, information can be transmitted and received through a plurality of channels, thereby improving communication stability and transmission efficiency.
In an embodiment, taking a compressed air station as an example, in order to ensure safe and reliable operation of the equipment group in the air station room, local and remote monitoring and control are required to be realized through automation and industrial internet of things technology. The multiple kinds of multiple equipment units in the air compression station room are connected with the edge server through a local wireless LoRa communication network to realize automation or industrial internet of things, and the equipment is monitored and controlled through the edge server. Specifically, a plurality of LoRa base stations (transmitting terminals) are arranged at a transmitting terminal of the communication system, a plurality of LoRa nodes (receiving terminals) are arranged at the receiving terminal, the LoRa nodes and the LoRa base stations are communicated in a mutual transparent transmission mode, and a master-slave structure is adopted to enable one LoRa base station to manage the plurality of LoRa nodes. The same communication channel is used between the LoRa base station and the LoRa nodes, and different communication channels can be used in one station house to form a plurality of groups of communication. Further loRa base station and edge server adopt LAN communication, have a plurality of loRa base stations and edge server communication in a station room, through the communication system who builds like this, can realize the automation and the industry thing of whole station room and ally oneself with the system. Referring to fig. 8, fig. 8 illustrates a communication principle between each LoRa base station and each LoRa node, where the specific communication is as follows: LoRa base stations 3-1, 3-2 and 3-3 carry out local area network communication with an edge server 5-1 through a switch 4-1, and simultaneously carry out LoRa bidirectional communication with LoRa nodes 2-1, 2-2 and 2-3 through a plurality of LoRa channels; LoRa nodes 2-1, 2-2 and 2-3 are connected with pressure sensors 1-1 and 1-2 and a controller 1-3 locally to carry out bidirectional communication of a field bus, so that automation and an industrial internet of things system of the whole station room are realized. Further, the LoRa nodes 2-1, 2-2 and 2-3 report the collected data of the pressure sensors 1-1 and 1-2 and the controller 1-3 to the edge server 5-1 through the LoRa base stations 3-1, 3-2 and 3-3 to analyze the data and display the data locally, and the edge server 5-1 manages the LoRa communication network according to the data and an algorithm and controls and adjusts the equipment below the LoRa nodes 2-1, 2-2 and 2-3.
When the edge server needs to collect device data or control device operation, an operation instruction is sent to the LoRa base station, and because there are multiple LoRa base stations and each LoRa base station corresponds to multiple LoRa channels, it is necessary to determine one LoRa base station among the multiple LoRa base stations as a target transmitting end, and select one LoRa channel among the multiple LoRa channels corresponding to the target transmitting end to transmit signals. Wherein, satisfying the operation instruction sending condition means: the edge server receives a control instruction for the device sent by the user or the current sending time of the operation instruction, for example, the edge server collects device data every 3 hours by default, and when the collecting time is reached, the sending condition meeting the operation instruction is determined, wherein the sending condition meeting the operation instruction can be determined according to the user requirement, and is not limited herein.
Further, referring to fig. 7, the step of determining the target transmitting end and the target channel includes:
step S11, obtaining the current communication time, and determining the target transmitting terminal according to the communication time;
step S12, obtaining operation information in the operation instruction, obtaining equipment to be operated in the operation information, and determining a receiving end where the equipment to be operated is located;
step S13, determining the target channel according to the receiving end where the device to be operated is located.
In this embodiment, the edge server only communicates with one LoRa base station at a certain time, e.g., at time T1, the edge server communicates with LoRa base station 3-1; at time T2, the edge server communicates with LoRa base station 3-2; at time T3, the edge server communicates with LoRa base station 3-3. Therefore, when the edge server sends an operation instruction to the LoRa base station, the current communication time is acquired in advance, and it is possible to determine which LoRa base station is currently in communication with according to the current communication time. In addition, each LoRa node has a unique 10-bit address, such as 2003020001, and each LoRa base station also has a unique 10-bit address, such as 2103020003. in the communication system, an edge server is provided, and the LoRa node and the LoRa base station in the system need to configure the address and the number of the node in the system, so as to determine the corresponding communication path according to the address and the number. After the target LoRa base station is determined, it is further required to determine which LoRa channel in the target LoRa base station is used for transmitting information, specifically, to obtain operation information in the operation instruction, to obtain a device to be operated in the operation information, to determine a receiving end where the device to be operated is located, and to determine a channel corresponding to the target transmitting end according to the receiving end where the device to be operated is located. If the current operation information is the pressure information collected by the pressure sensor 1-1, and the receiving end corresponding to the pressure sensor 1-1 is the LoRa node 2-1, at this time, the edge server can know the address and the number of the LoRa node 2-1, so as to determine the corresponding LoRa channel transmission operation instruction.
Step S20, sending the operation instruction to the device side through the target channel, so that the device side executes a corresponding operation according to the operation instruction.
In this embodiment, after determining the LoRa base station and the LoRa channel, the edge server directly sends the operation instruction to the device side through the LoRa channel, and after receiving the operation instruction, the device side obtains operation information corresponding to the operation instruction and executes corresponding operation according to the operation information. In an embodiment, when an edge server sends an operation through an LoRa channel 1 in an LoRa base station 3-1, an LoRa node 2-1 receives an operation instruction, the LoRa node 2-1 sends the operation instruction to a pressure sensor 1-1, the pressure sensor 1-1 further analyzes the operation instruction, so as to obtain a content corresponding to the operation instruction, if the content is to control the pressure sensor 1-1 to be started, the pressure sensor 1-1 executes a start operation, and returns an execution result to the edge server; if the content is the pressure data of the pressure sensor 1-1, the pressure sensor 1-1 executes the pressure data acquisition operation and returns the acquired pressure data to the edge server in an original way.
When the condition for sending the operation instruction is met, the target transmitting terminal and the target channel are determined; and sending the operation instruction to the equipment end through the target channel so that the equipment end executes corresponding operation according to the operation instruction. LoRa communication is realized through a plurality of receiving terminals and a plurality of transmitting terminals, so that data can be transmitted based on a plurality of communication channels, and the stability and the transmission efficiency of communication are improved. In addition, the system can be assisted to operate stably and reliably, the air compressor can be effectively operated alternately to balance the working condition of the machine, air compressor resources are reasonably configured, and control is optimized, so that the operation efficiency of the equipment is improved, the service life of the electromechanical equipment is prolonged, and the operation and maintenance cost is reduced.
Further, referring to fig. 3, a second embodiment of the LoRa communication method of the present application is proposed.
The second embodiment of the LoRa communication method is different from the first embodiment of the LoRa communication method in that, after the step of sending the operation command to the device side through the target channel, the method includes:
step S21, obtaining the communication quality of each channel;
step S22, determining a current communication condition according to the communication quality, and performing different channel configuration operations according to the communication condition, wherein the channel configuration at least includes channel optimization and channel switching.
In this embodiment, in the communication process, the edge server may detect the communication quality of each LoRa channel in real time, determine the current communication condition according to the communication quality, and perform different channel configuration operations according to the communication condition, where the communication condition includes a channel failure, a weak communication signal, a base station failure, a node failure, an abnormal connection, an abnormal data acquisition, and the like. If the base station and the node are normal, but the corresponding channel can not transmit any information, determining that a channel fault occurs; if the current communication signal strength does not meet the set strength value, determining that the communication signal is weak; and if the current base station, the node and the channel are normal, but the edge server cannot acquire the data of the equipment end, determining that the data acquisition is abnormal. Different communication abnormal conditions have different channel configuration operations, and the channel configuration at least comprises channel switching, channel optimization, communication protocol modification and the like. Further, the step of performing different channel configuration operations according to the communication situation includes:
if the communication condition is a first communication condition, sending a channel switching instruction to the target transmitting terminal so that the target transmitting terminal performs channel switching operation according to the channel switching instruction;
and if the communication situation is the second communication situation, executing channel optimization operation.
In this embodiment, the first communication condition refers to a channel fault, a base station fault, a node fault, and the like, and when the first communication condition occurs, the operation sequence and the operation rule of the faulty LoRa base station are modified through an algorithm of the edge server, and meanwhile, the LoRa channel configuration of other LoRa base stations is modified, and the faulty LoRa base station is replaced to realize safe and stable operation of the system. In an embodiment, the edge server sends a channel switching instruction to the LoRa base station, where the channel switching instruction includes a channel path to be switched, and the LoRa base station directly executes a channel switching operation after receiving the channel switching instruction, and switches the failed channel to a channel with normal communication.
The second communication condition is signal abnormality, such as weak communication signal, unstable communication, transmission efficiency, etc., and when the first communication condition occurs, the edge server automatically performs channel optimization, such as adjusting the transmission power of the base station, switching channels, adjusting the communication frequency, etc. In an embodiment, the signal strength is used as a determination index of the communication quality, wherein when the communication quality is within a range of 2db-10db, it indicates that the communication signal of the current channel is weak, the edge server sends a transmission power modification instruction to the LoRa base station, where the transmission power modification instruction includes a required transmission power value, and the LoRa base station directly adjusts the current transmission power operation after receiving the transmission power modification instruction, so as to improve the strength of the communication signal and ensure the communication quality.
The embodiment determines the current communication condition according to the communication quality by acquiring the communication quality of each channel, and executes different channel configuration operations according to the communication condition, thereby ensuring the safe and stable operation of the system.
Further, referring to fig. 4, a third embodiment of the LoRa communication method of the present application is proposed.

In this embodiment, the operation instruction of the edge server mainly includes two types, one is a control type, and the other is an acquisition type, and different operation types are provided with different priorities, where the priority refers to an execution priority. In the communication process, the edge server acquires the operation type of the operation instruction, determines the priority corresponding to the operation instruction according to the operation type, and determines the execution sequence of the operation instruction according to the priority. Specifically, if the operation type is the control type, determining that the priority corresponding to the operation instruction is a first priority; and if the operation type is the acquisition type, determining that the priority corresponding to the operation instruction is a second priority, wherein the execution sequence of the first priority is before the second priority. That is, the control command is prior to the data collecting command, so as to ensure that the control command is executed with the highest priority, and the data collection is collected in a continuous cycle.
In the embodiment, the operation type of the operation instruction is obtained, the priority corresponding to the operation instruction is determined according to the operation type, and the execution sequence of the operation instruction is determined according to the priority, wherein the priority of the control instruction is higher than the priority of the data acquisition instruction, that is, a control priority policy is set, so that the control instruction is guaranteed to be executed with the highest priority.

and step S17, determining the data acquisition frequency according to the importance degree, wherein the acquisition frequency is associated with the frequency of sending the operation instruction to the equipment terminal.
In this embodiment, since the edge server needs to collect various types of device data, such as: the operation data, the pressure data, the temperature data and the like, and the corresponding importance degrees of different equipment data are different, for example, the pressure data is the most important data in an air compression station room. When the edge server collects the equipment data, the data collection is divided into a plurality of levels in advance, such as an important level, a secondary level and a general three-level; or primary, secondary, tertiary and the like, and the data acquisition grade corresponds to the importance degree of the acquired data.
