In order to make the technical scheme of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings.
Long Range wireless communication (LoRa) is a low power wireless communication technology, and is particularly suitable for Long-Range, low-rate internet of things (IoT) applications. The LoRa technique employs a technique called "spread spectrum modulation" that achieves longer communication distances and strong interference immunity by transmitting a narrower bandwidth over a wider frequency band. The LoRa technology has excellent transmission distances, which can reach several kilometers to tens of kilometers, depending on the equipment and environmental conditions.
Currently, the LoRa gateway is mostly used for communication connection of low-power consumption and long-distance terminal equipment, including but not limited to environmental parameter sensors, small unmanned aerial vehicles, monitoring equipment and the like. In a ski resort, a large number of terminals are usually required for a plurality of LoRa gateways to be connected to a plurality of terminals, respectively, due to a large surface area. In the skiing season, along with the increase of skiers (hereinafter referred to as users) in a skiing field, the number of terminal devices is also increased, at this time, in the skiing field, when the total number of the LoRa gateways is unchanged, a single LoRa gateway can simultaneously process wireless communication connection of more terminal devices, at this time, a larger load can cause abnormal operation conditions of the LoRa gateway, and the abnormal operation conditions can cause the problem that the efficiency is lower or the data of the terminal devices cannot be acquired when the data of the terminal devices are acquired.
Therefore, there is a need for a wireless communication method, apparatus and electronic device based on LoRa.
Referring to fig. 1, a schematic diagram of an application scenario based on the LoRa according to an embodiment of the present invention is shown, the method is applied to a POE switch 100, the POE switch 100 is connected to a first LoRa gateway 101, a second LoRa gateway 102, a third LoRa gateway 103 and a standby LoRa gateway 104 through wireless communication, and the first LoRa gateway 101 is connected to a plurality of terminal devices 105 through wireless communication.
Referring to fig. 2, a flow chart of a wireless communication method based on LoRa according to an embodiment of the present invention is shown, and the method is applied to a POE switch 100, and the flow chart mainly includes the following steps: s201 to S204.
Step S201, a first operation state of the first LoRa gateway 101 is acquired.
Specifically, since the area of the skiing field is larger, the skiing field may be divided into a plurality of areas, and the POE switch 100 corresponding to the area and a plurality of LoRa gateways for performing wireless communication connection with the terminal device 105 in the area are set in each area, where the POE switch 100 in each area is used to control the plurality of LoRa gateways in the area, and obtain the running state of each LoRa gateway in real time, where the running state also includes the first running state of the first LoRa gateway 101. The number of the LoRa gateways set in each area is not limited in this embodiment, and in a ski resort, the number of the LoRa gateways in each area needs to be set according to the actual situation of the ski resort, where factors to be considered include the area of the ski resort, the geographical environments of different areas, the user densities of different areas, the communication ranges of the LoRa gateways, and the like. This embodiment is described in terms of POE switch 100 and multiple LoRa gateways in one zone and in that zone in the following steps.
In step S202, if the first operation state is confirmed to be the abnormal operation state, the standby LoRa gateway 104 is obtained.
Specifically, the POE switch 100 in one area can be connected to a plurality of standby LoRa gateways 104 in addition to being capable of wireless communication with the plurality of LoRa gateways, and the plurality of LoRa gateways includes, but is not limited to, a first LoRa gateway 101, a second LoRa gateway 102, and a third LoRa gateway 103, and the first LoRa gateway 101, the second LoRa gateway 102, and the third LoRa gateway 103 refer to all LoRa gateways connected to the POE switch 100 in wireless communication with the exception of the standby LoRa gateway 104. The POE switch 100 acquires the running state of each LoRa gateway in the area in real time, and when there is an abnormal LoRa gateway in the area, the POE switch 100 acquires a plurality of standby LoRa gateways 104, for example, when the POE switch 100 detects that the first LoRa gateway 101 is abnormal, the POE switch 100 acquires a plurality of standby LoRa gateways 104.
In one possible implementation, step S202 further includes: transmitting a plurality of test data to the plurality of terminal devices 105 through the first LoRa gateway 101 at each first time period; acquiring a plurality of test data from the sending to the returning of the plurality of second time periods of the first LoRa gateway 101; one test data corresponds to one second time period; obtaining tie times of a plurality of second time periods; and if the average time is greater than the preset average time, confirming that the first running state is an abnormal running state.
Specifically, every first period of time, POE switch 100 needs to detect the operation status of each of the LoRa gateways in the area, taking first LoRa gateway 101 as an example. The POE switch 100 transmits one test data to each of the terminal equipments 105 connected in wireless communication with the first LoRa gateway 101 through the first LoRa gateway 101, and acquires a plurality of second time periods required for each test data to be transmitted from the POE switch 100 to the first LoRa gateway 101, to each of the terminal equipments 105, to the first LoRa gateway 101 from the terminal equipment 105, and to the POE switch 100. The POE switch 100 calculates the average time of the plurality of second time periods, compares the magnitude relation between the average time and the preset average time, and if the average time is smaller than the preset average time, indicates that no abnormality occurs in the first LoRa gateway 101; if the average time is greater than the preset average time, it is indicated that the first LoRa gateway 101 is abnormal, and the first running state corresponding to the first LoRa gateway 101 is confirmed to be the abnormal running state. In this embodiment, the setting of the preset average time may be accurate to a fraction of a second or even a millisecond, so that the case where the average time is equal to the preset average time will not generally occur, and if so, the average time of the plurality of second time periods may be recalculated, and the first running state corresponding to the first LoRa gateway 101 may be determined again, or the POE switch 100 directly sets the case where the average time is equal to the case where no abnormality occurs in the first LoRa gateway 101, which is not limited in this embodiment.
Step S203, determine whether the standby LoRa gateway 104 is in an idle state.
Specifically, each time a terminal device 105 performs a wireless communication connection with the LoRa gateway, a certain memory of the LoRa gateway is occupied, and the size of the memory occupancy depends on the performance of the terminal device 105, and the higher the performance of the terminal device 105, the more memory of the LoRa gateway is occupied, i.e. the larger the memory occupancy value of the terminal device 105. The ratio of the sum of memory occupancy values of the terminal devices 105 that the LoRa gateway performs wireless communication connection to the total memory that the LoRa gateway can accommodate is the occupancy rate of the LoRa gateway. The POE switch 100 determines whether the standby LoRa gateways 104 are in an idle state, that is, determines whether there are standby LoRa gateways 104 with full occupancy rate in all the standby LoRa gateways 104, by setting a preset memory occupancy threshold (the preset memory occupancy threshold is less than or equal to 100%) for the standby LoRa gateways 104, and when the occupancy rate of the terminal device 105 in the standby LoRa gateways 104 is less than the preset memory occupancy threshold, it indicates that the standby LoRa gateways 104 are in the idle state.
In step S204, if the standby LoRa gateway 104 is in the idle state, the plurality of terminal devices 105 are connected by wireless communication through the standby LoRa gateway 104.
Specifically, POE switch 100 acquires all standby LoRa gateways 104 in an idle state, and connects all terminal devices 105 that are in wireless communication connection with first LoRa gateway 101 in which an abnormality occurs, respectively, to one or more standby LoRa gateways 104. In this step, since the number of the terminal devices 105 wirelessly connected to the first abnormal LoRa gateway 101 is not determined, the number of the standby LoRa gateways 104 required is also not determined, when the number of the terminal devices 105 is large, a plurality of standby LoRa gateways 104 may be required to process, at this time, the terminal devices 105 are preferentially connected to the standby LoRa gateways 104 with a small occupancy rate, in this process, when the occupancy rate of the standby LoRa gateways 104 is greater than the preset memory occupancy threshold, if the number of the terminal devices 105 remains, the standby LoRa gateways 104 with other idle states are obtained, and the remaining terminal devices 105 are connected to the standby LoRa gateways 104 with other idle states in a wireless communication manner until all the terminal devices 105 are connected to the standby LoRa gateways 104 in a wireless communication manner or the standby LoRa gateways 104 with other idle states do not exist in the POE switch 100.
In one possible implementation, step S204 further includes: if the standby LoRa gateway 104 is not in the idle state, acquiring a second operation state of the second LoRa gateway 102 and a third operation state of the third LoRa gateway 103; if the second running state and the third running state are not abnormal running states, acquiring a first occupancy rate of the second loRa gateway 102 and a second occupancy rate of the third loRa gateway 103; judging whether the first occupancy rate is smaller than the second occupancy rate; if the first occupancy rate is smaller than the second occupancy rate, the plurality of terminal devices 105 are preferentially connected in wireless communication through the second LoRa gateway 102.
Specifically, if there is no other standby LoRa gateway 104 in an idle state in the POE switch 100, the POE switch 100 needs to connect the terminal equipment 105 which fails to connect to the standby LoRa gateway 104 in wireless communication with other LoRa gateways. It should be noted that, in order to ensure the safety of the user in the skiing field, the terminal device 105 should be connected with the LoRa gateways in a communication manner as soon as possible, because the number of standby LoRa gateways is far less than that of other LoRa gateways, the process of searching for the standby LoRa gateway 104 in an idle state and connecting the standby LoRa gateway 104 with the terminal device 105 in a wireless manner is faster than that of connecting the standby LoRa gateway 104 with the first LoRa gateway 101, the second LoRa gateway 102 and the third LoRa gateway 103, at this time, the POE switch 100 can now connect the terminal device 105 with the standby LoRa gateway 104 in a wireless manner, and when no standby LoRa gateway 104 in other idle state exists in the POE switch 100, other LoRa gateways which are connected with the POE switch 100 in a wireless manner except for the standby LoRa gateway 104 and the first LoRa gateway 101 are found if the memory occupation is not full. At this time, the POE switch 100 obtains the LoRa gateway with the lowest occupancy rate from all the LoRa gateways that are not in the abnormal operation state, that is, the second LoRa gateway 102 and the third LoRa gateway 103, that is, when the first occupancy rate of the second LoRa gateway 102 is smaller than the second occupancy rate of the third LoRa gateway 103, the second LoRa gateway 102 is the LoRa gateway with the lowest occupancy rate, and preferentially connects the plurality of terminal devices 105 through the second LoRa gateway 102 in a wireless communication manner, where the first occupancy rate and the second occupancy rate are not all satisfied.
In one possible implementation, after step S204, the method further includes: judging whether the first occupancy rate is larger than a preset occupancy rate or not; if the first occupancy rate is greater than the preset occupancy rate, acquiring a first memory occupancy value of a first terminal device in wireless communication connection with the second loRa gateway 102, and acquiring a second memory occupancy value of a second terminal device in wireless communication connection with the second loRa gateway 102; the first terminal device and the second terminal device are any two different terminal devices from a plurality of terminal devices which are in wireless communication connection with the second LoRa gateway 102; acquiring whether the first memory occupation value is smaller than the second memory occupation value; if the first memory occupancy value is smaller than the second memory occupancy value, the wireless communication connection between the first terminal device and the second LoRa gateway 102 is released preferentially.
Specifically, in the process of performing wireless communication connection between the plurality of terminal devices 105 and the second LoRa gateway 102, when the first occupancy rate of the second LoRa gateway 102 is full, that is, when the first occupancy rate of the second LoRa gateway 102 is greater than the preset occupancy rate, acquiring memory occupancy values corresponding to all the terminal devices 105 that perform wireless communication connection with the second LoRa gateway 102, and calculating to acquire the terminal device 105 that performs wireless communication connection with the second LoRa gateway 102 corresponding to the smallest memory occupancy value, that is, the first terminal device, and releasing the wireless communication connection between the first terminal device and the second LoRa gateway 102; if the occupancy rate of the second LoRa gateway 102 is still full at this time, repeating the above steps, and continuing to release the terminal device 105 having the smallest memory occupancy value and performing wireless communication connection with the second LoRa gateway 102 until the first occupancy rate of the second LoRa gateway 102 is smaller than the preset occupancy rate. Then, POE switch 100 inquires of the other LoRa gateway whose occupancy rate is not full, and connects terminal device 105 disconnected from wireless communication with second LoRa gateway 102 in wireless communication therewith.
For example, if the preset occupancy rate is set to be more than 80%, that is, the occupancy rate of the proxy LoRa gateway is full, at this time, the first occupancy rate of the second LoRa gateway 102 is 86%, then all the memory occupancy values corresponding to the terminal devices 105 that are in wireless communication connection with the second LoRa gateway 102 are obtained respectively, and if the memory occupancy values corresponding to the terminal devices a-F are 30%, 10%, 5%, 10%, and 3%, respectively, the wireless communication connection between the terminal device F and the second LoRa gateway 102 corresponding to the minimum memory occupancy value of 3% is released, after the release, the first occupancy rate of the second LoRa gateway 102 is 83%, at this time, the first occupancy rate is still full, at this time, the wireless communication connection between the terminal device D corresponding to the minimum memory occupancy value of 5% and the second LoRa gateway 102 is continuously released, after the release, the first occupancy rate of the second LoRa gateway 102 is 78%, and the release operation is ended. The POE switch 100 can then connect the released terminal device F and terminal device D to other LoRa gateways in wireless communication. It should be noted that, the memory occupancy value of the internal terminal device 105 is assumed for convenience of description, and in an actual scenario, the memory occupancy value of the terminal device 105 is far smaller than that in the above example, and the memory occupancy value of one terminal device 105 is approximately between tens of kilobytes and hundreds of kilobytes.
In a possible implementation, after step S204, the data processing performance of the standby LoRa gateway 104 is smaller than the first, second and third LoRa gateways 101, 102, 103, and the method further includes: acquiring a first processing priority corresponding to the third terminal equipment from a priority database; the third terminal device is any one terminal device 105 among the plurality of terminal devices 105; judging whether the first processing priority is greater than a preset priority; if the first processing priority is greater than the preset priority, acquiring a fourth running state of the second LoRa gateway 102 and a fifth running state of the third LoRa gateway 103; if the fourth operation state and the fifth operation state are not abnormal operation states, acquiring a third occupancy rate of the second LoRa gateway 102 and a fourth occupancy rate of the third LoRa gateway 103; judging whether the third occupancy rate is smaller than the fourth occupancy rate; if the first occupancy rate is smaller than the second occupancy rate, the third terminal device is preferentially connected in wireless communication through the second LoRa gateway 102.
Specifically, since the data processing performance of the standby LoRa gateway 104 is smaller than that of the first LoRa gateway 101, the second LoRa gateway 102 and the third LoRa gateway 103, after the process of performing wireless communication connection between the plurality of terminal devices 105 and the standby LoRa gateway, the POE switch 100 can switch the terminal device 105 that performs wireless communication connection with the standby LoRa gateway to the terminal device 105 with higher priority to perform wireless communication connection with the LoRa gateway that does not have an abnormal operation state. In a ski resort, it is important to confirm the safety of the user, so that the POE switch 100 also needs to obtain the data sent by the terminal device 105 with higher processing priority preferentially, and if the processing priority of the third terminal device is greater than that of the second terminal device, the third terminal device is connected to the second LoRa gateway 102 with smaller occupancy rate in a wireless communication manner.
In a possible implementation, step S204 further includes building a priority database: acquiring first processing data of a third terminal device, wherein the first processing data comprises position data, time data and heart rate data; setting a first processing priority corresponding to the third terminal equipment according to the first processing data; and storing the first corresponding relation among the third terminal equipment, the first processing priority and the first processing priority in a priority database.
Specifically, the priority of the terminal device 105 is confirmed by the actual use of the device. In a ski resort, there are a number of terminal devices 105 such as a monitoring device, a renting device, etc. provided in the ski resort in addition to the terminal devices 105 worn by the user, such as a timer device, a positioning device, a heart rate detecting device, an altitude detecting device, etc., and the POE switch 100 sets a processing priority level for each device according to the importance of the data to be processed by each device, the processing priority level being related to the safety of the user, the higher the processing priority level of the terminal device 105 is the more reflective of the safety of the user the data to be processed by the terminal device 105 is, and the POE switch 100 associates each processing priority level with each terminal device 105 and the correspondence of each processing priority level with each terminal device 105 is stored in a priority database.
In one possible implementation, after step S204, the method further includes: acquiring second processing data of third terminal equipment at intervals of a first time period; judging whether the second processing data is larger than the safety data or not; if the second processing data is larger than the safety data, changing the first processing priority corresponding to the third terminal equipment into the second processing priority, wherein the second processing priority is larger than the first processing priority; and storing the second corresponding relation among the third terminal equipment, the second processing priority and the second processing priority in a priority database.
Specifically, the processing priority corresponding to the terminal device 105 in the priority database may be updated at any time, and the POE switch 100 determines whether the processing data of a certain terminal device 105 is greater than the security data; if the processing data of the terminal device 105 is greater than the safety data, it is indicated that the user has a safety hazard in the ski resort. At this time, the POE switch 100 increases the processing priority corresponding to the terminal device 105, and sends a danger notification to the staff in the ski resort, so that the staff can immediately rescue the user.
By adopting the method, the beneficial effects which can be achieved include at least one of the following:
1. Through adopting above-mentioned technical scheme, POE switch acquires every loRa gateway's running state in real time, if POE switch detects the loRa gateway of unusual running state, first loRa gateway promptly, through the reserve loRa gateway that acquires idle state, can switch all terminal equipment who carries out wireless communication connection with first loRa gateway to carry out wireless communication connection with idle state's reserve loRa gateway, thereby solve the problem that the efficiency that the situation of unusual operation can appear is lower or can't acquire terminal equipment's data when acquireing terminal equipment data.
2. By setting the processing priority of each terminal device, the POE exchanger can switch the terminal device with higher priority from the terminal device which is in wireless communication connection with the standby LoRa gateway to the terminal device which is in wireless communication connection with the LoRa gateway with no abnormal operation state, and the terminal device with higher priority is in wireless communication connection with the LoRa gateway with abnormal operation state according to the sequence of wireless communication connection from high processing priority to low processing priority, so that the POE exchanger can obtain the data sent by the terminal device with higher processing priority.
3. Since it is important to confirm the safety of the user in the ski resort, the processing priority is closely related to the safety of the user, and the higher the data to be processed by the terminal device can reflect the safety of the user, the higher the processing priority of the terminal device. The POE exchanger can ensure the safety of the user in the skiing field to a greater extent by preferentially acquiring the data sent by the terminal equipment with higher processing priority.
