Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Long Range Radio (LoRa) is a low power local area network wireless standard created by Semtech corporation. loRa possesses characteristics such as low-power consumption, low cost, transmission distance are far away, the network deployment is easy, and the wide application is in internet of things fields such as wisdom community, intelligent house, smart meter, wisdom agriculture, intelligent commodity circulation.
In the existing LoRa networking system, multiple channels, some 8 channels, some 32 channels, may be supported in one LoRa networking system, and the LoRa devices located in different channels cannot communicate with each other, and generally, the channels of all the LoRa devices of one LoRa network are the same.
The communication protocol of the existing loRa equipment is fixed, the encryption mode is simple, all the loRa equipment are in the same channel, and therefore a network attacker can obtain data of the loRa equipment after determining the address and the channel of the loRa equipment, and further malicious control is carried out on each loRa equipment in the channel through analyzing the communication protocol of the loRa equipment, and serious network security problems are caused.
Based on this, the applicant proposes a communication method and device based on the LoRa channel, and an LoRa host, which are used for solving the above problems.
Referring to fig. 1, fig. 1 is a flowchart of a communication method based on an LoRa channel according to an embodiment of the present disclosure, where the communication method based on the LoRa channel is applied to an LoRa host, and includes the following steps:
step S101: and acquiring the current configuration information of the LoRa slave machine.
Step S102: and switching to a first channel where the LoRa slave is located and sending configuration information to the LoRa slave.
Step S103: and switching to a channel corresponding to the channel information to be configured and communicating with the LoRa slave machine based on the configuration information.
The above-described flow will be described in detail below.
Step S101: and acquiring the current configuration information of the LoRa slave machine.
In the embodiment of the present application, when the LoRa master needs to communicate with the LoRa slave, first, current configuration information of the LoRa slave is acquired. The current configuration information may include the address information of the first channel where the LoRa slave is located and the LoRa slave. In a LoRa networking system, communication can be performed between a LoRa master and a LoRa slave in the same channel. Therefore, when the LoRa master needs to communicate with the LoRa slave, the LoRa master needs to acquire channel information of the LoRa slave.
Step S102: and switching to a first channel where the LoRa slave is located and sending configuration information to the LoRa slave.
In the embodiment of the application, after the configuration information of the LoRa slave is obtained, the LoRa master is switched to the first channel where the LoRa slave is located, and the configuration information is sent to the LoRa slave, wherein the configuration information includes address information to be configured and channel information to be configured, and an address corresponding to the address information to be configured is different from an address of the LoRa master.
And after receiving the configuration information, the LoRa slave machine carries out configuration change according to the configuration information. Specifically, the LoRa slave switches itself from the first channel to the channel corresponding to the channel information to be configured and switches itself from the previous address to the address corresponding to the address information to be configured according to the channel information to be configured and the address information to be configured in the configuration information.
Step S103: and switching to a channel corresponding to the channel information to be configured and communicating with the LoRa slave machine based on the configuration information.
In the embodiment of the application, after the LoRa master sends the configuration information to the LoRa slave, the LoRa master switches from the first channel to the channel corresponding to the channel information to be configured in the configuration information, and communicates with the LoRa slave based on the configuration information.
It should be noted that, when the LoRa master needs to communicate with the LoRa slave, the steps S101 to S103 are executed. In other words, before communicating with the LoRa slave, the LoRa master switches to the channel where the LoRa slave is located, sends the configuration information to enable the LoRa slave to change the configuration information of the LoRa slave, enables the LoRa slave to update the original channel and address into the channel and address in the configuration information, then switches to the updated channel of the LoRa slave, and communicates with the LoRa slave according to the configuration information sent before. By the method, even if a network attacker determines the address and the channel of one LoRa slave machine in the communication process of the LoRa master machine and the LoRa slave machine, the address and the channel of the LoRa slave machine can be reconfigured before the LoRa master machine and the LoRa slave machine carry out next communication, so that the network attacker cannot steal information of the communication of the LoRa slave machine according to the address and the channel obtained in the previous communication, and the communication safety between the LoRa master machine and the LoRa slave machine is effectively improved.
In the prior art, the number of LoRa slaves that can be accommodated by one channel is 255. Since the LoRa master and the LoRa slave are both located in the same channel, the number of LoRa slaves that can be covered by one LoRa master is 255. According to the communication method based on the LoRa channels provided by the embodiment of the application, if the LoRa master can support 32 channels, since the LoRa master can be switched to different channels to communicate with the LoRa slave in each channel, one LoRa master can cover 255 × 32 LoRa slaves.
Therefore, the number of the LoRa slaves capable of being accommodated in one channel is limited, and the channels of the LoRa slaves are configured, so that each LoRa slave in the LoRa networking system can be located in different channels, the number of the LoRa slaves covered by the LoRa master is increased, a network attacker is prevented from maliciously controlling other LoRa slaves in the channel by analyzing the communication protocol of the LoRa slaves, and the safety of the LoRa networking system is improved.
Specifically, the steps S101 to S103 are described below with reference to a specific example.
As shown in fig. 2, it is assumed that an LoRa networking system includes an LoRa master, four LoRa slaves: LoRa slave 1, LoRa slave 2, LoRa slave 3, and LoRa slave 4.
The initial configuration information of the LoRa host is channel 1, address 1, that is, the location of the LoRa host in the LoRa networking system is channel 1, address 1. The configuration information of each LoRa slave is shown in table 1 below:
lora slave serial number Lora slave address Lora channel
1 2 2
2 3 3
3 4 4
4 5 5
TABLE 1
As can be seen from table 1, the initial configuration information of the LoRa slave 1 is channel 2, address 2; the initial configuration information of the LoRa slave machine 2 is channel 3 and address 3; the initial configuration information of the LoRa slave 3 is channel 4 and address 4; the initial configuration information of the LoRa slave 4 is channel 5, address 5.
When the LoRa master needs to communicate with the LoRa slave 1, configuration information of the LoRa slave 1 is first obtained, that is, the LoRa slave 1 is in channel 2 and address 2 (that is, channel 2 is the first channel). The LoRa master then switches from channel 1, address 1 to channel 2, address 1, and sends configuration information to LoRa slave 1. The configuration information may be channel 6 and address 6 (that is, channel 6 is a channel corresponding to the information of the channel to be configured, and address 6 is an address corresponding to the information of the address to be configured). The LoRa slave 1 switches itself from channel 2, address 2 to channel 6, address 6 according to the configuration information. The LoRa master then switches from channel 2 to channel 6 and communicates with LoRa slave 1 based on the configuration information. It should be noted that, in one channel, the addresses of the LoRa master and the LoRa slave cannot be repeated, and therefore, the address corresponding to the address information to be configured needs to be different from the address of the LoRa master, so as to ensure that no error occurs in the communication process.
In addition, if the LoRa master needs to communicate with the LoRa slave 2, the LoRa slave 3, or the LoRa slave 4, the communication method is the same as that of the LoRa master and the LoRa slave 1, and the same or similar parts may be referred to each other for brevity of description, and therefore, the details are not repeated.
As an optional implementation manner, after step S102, the method may further include: and receiving configuration information confirmation information sent by the LoRa slave machine.
In this embodiment of the application, the LoRa master may be a point-to-point half-duplex LoRa master, and the LoRa slave may be a point-to-point half-duplex LoRa slave, that is, the LoRa master may actively send data to the LoRa slave, and the LoRa slave may not actively send data to the LoRa master, and when the LoRa slave receives the data sent by the LoRa master, the LoRa slave may reply a response frame to the LoRa master.
If the LoRa slave can normally communicate with the LoRa master, after receiving the configuration information sent by the LoRa master, the LoRa slave sends configuration information confirmation information to the LoRa master as a response frame to indicate that the LoRa slave has normally received the configuration information sent by the LoRa master. After receiving the configuration information confirmation information, the LoRa master assumes that the LoRa slave has normally received the configuration information and updates the channel and the address according to the configuration information. Then, the LoRa master further performs step S103 to switch to a channel corresponding to the channel information to be configured and communicate with the LoRa slave based on the configuration information.
If communication abnormality occurs between the LoRa slave and the LoRa master, that is, the LoRa slave does not receive the configuration information sent by the LoRa master or the LoRa slave cannot send configuration information confirmation information to the LoRa master after receiving the configuration information sent by the LoRa master. At this time, if the LoRa master does not receive the configuration information confirmation information sent by the LoRa slave within the preset time, it indicates that the sending of the configuration information is failed, and the LoRa master may execute step S102 again to send the configuration information to the LoRa slave.
By receiving the configuration information confirmation information sent by the LoRa slave, it can be ensured that the LoRa slave has received the configuration information sent by the LoRa master.
As an alternative embodiment, the LoRa master may store therein a configuration information list, where the configuration information list includes the number of the LoRa slave and the corresponding current configuration information of the LoRa slave. Specifically, the configuration information list may be the same as table 1 described above. When the LoRa master needs to communicate with a certain LoRa slave, the LoRa master may obtain current configuration information of the LoRa slave from the configuration information list.
As an alternative, the LoRa host may store the configuration information list in the chip of the LoRa host, that is, write the configuration information list in the flash of the LoRa host chip.
In addition, the LoRa host can upload the configuration information list to the cloud and store the configuration information list in a remote database. When the inquiry is needed, the configuration information list stored in the remote database is inquired in a remote access mode.
Before step S102, in order to ensure that the configuration information sent by the LoRa master to the LoRa slave does not conflict with the configuration information of other LoRa slaves, the method further includes:
and generating the configuration information according to the configuration information list so as to ensure that the generated configuration information is different from the configuration information in the configuration information list.
In this embodiment of the present application, a plurality of LoRa devices may exist in one LoRa networking system, and in order to ensure that configuration information among the LoRa devices does not conflict, when the configuration information is sent to the LoRa slave, it is necessary to generate the configuration information according to the current configuration information list and ensure that the generated configuration information is different from the configuration information of each LoRa device in the current LoRa networking system, thereby avoiding communication failure caused by the same configuration information.
As an optional implementation manner, in an LoRa networking system, addresses of LoRa devices in one channel cannot be the same, and addresses of LoRa devices in different channels may be the same or different. Therefore, it is first determined whether the address to be configured in the generated configuration information is the same as the address in the configuration information list. And if the address to be configured in the address information to be configured is different from the addresses of all the current LoRa equipment, the generated configuration information does not conflict with the configuration information of other LoRa equipment. If the address of a certain LoRa device is the same as the address to be configured in the information of the address to be configured, further judging whether a channel of the LoRa device is the same as the channel to be configured in the generated information to be configured, if not, the generated configuration information does not conflict with the configuration information of other LoRa devices; if the configuration information is the same as the configuration information in the configuration information list, a new configuration information needs to be generated again to ensure that the generated configuration information is different from the configuration information in the configuration information list.
As an optional implementation manner, before step S103, the method further includes:
sending a verification communication frame to the LoRa slave machine; if the verification communication response frame sent by the LoRa slave machine is not received within the preset time, switching to a first channel where the LoRa slave machine is located and sending configuration information to the LoRa slave machine; and if the verification communication response frame sent by the LoRa slave machine is received within the preset time, updating the configuration information list based on the configuration information and the number information of the LoRa slave machine.
In the embodiment of the application, after the LoRa master switches to the channel corresponding to the channel information to be configured, in order to ensure that the LoRa slave updates the channel and the address according to the configuration information sent by the LoRa master before, the LoRa master sends a verification communication frame to the LoRa slave.
If the verification communication response frame sent by the LoRa slave is not received within the preset time, the LoRa slave is considered not to update the channel and the address according to the configuration information, and the channel of the LoRa slave is still in the first channel at this time. Therefore, the LoRa master switches to the first channel and sends the configuration information to the LoRa slave again, i.e., step S102 is repeated.
And if an authentication communication response frame sent by the LoRa slave machine is received within the preset time, the LoRa slave machine is considered to update the channel and the address according to the configuration information. Therefore, the configuration information list is updated based on the configuration information and the number information of the LoRa slave, so that the current configuration information of the LoRa slave can be obtained based on the updated configuration information list when the LoRa slave is communicated next time.
When the LoRa host updates the configuration information list, the update method is different for different configuration information list storage methods. If the configuration information list is stored in the chip of the LoRa host, writing the updated configuration information list into the flash of the chip of the LoRa host; and if the configuration information list is stored in the remote database, changing the configuration information list in the remote database by the updated configuration information list in a remote access mode.
In the embodiment of the application, a verification communication frame is sent to the LoRa slave machine, whether the LoRa slave machine updates the channel and the address according to the configuration information can be determined according to whether the LoRa slave machine replies a verification communication response frame, and if the verification communication response frame is received, the LoRa slave machine is indicated to finish updating the channel and the address and can perform communication; if the verification communication response frame is not received, the configuration information is sent to the LoRa slave again when the LoRa slave does not complete updating the channel and the address, and the situation that the LoRa master cannot communicate with the LoRa slave due to the fact that the LoRa slave does not complete updating the channel and the address is avoided.
As an optional implementation manner, when the LoRa master sends the configuration information to the LoRa slave, the LoRa master performs public key encryption on the configuration information and sends the encrypted configuration information to the LoRa slave. And the LoRa slave machine receives the encrypted configuration information, and decrypts the public key of the encrypted configuration information to obtain the configuration information. By carrying out public key encryption on the configuration information, the security in the transmission process of the configuration information can be improved.
The embodiment of the application provides a communication method based on an LoRa channel, wherein before each time of communication with an LoRa slave, an LoRa master is switched to a channel where the LoRa slave is located, configuration information is sent to enable the LoRa slave to change configuration information of the LoRa slave, the LoRa slave is updated to a channel and an address in the configuration information from an original channel and address, then the LoRa master is switched to an updated channel of the LoRa slave, and communication with the LoRa slave is performed according to the configuration information sent before. By the method, even if a network attacker determines the address and the channel of one LoRa slave machine in the communication process of the LoRa master machine and the LoRa slave machine, the LoRa master machine can reconfigure the address and the channel of the LoRa slave machine before the LoRa slave machine carries out the next communication, so that the network attacker cannot steal information of the communication of the LoRa slave machine according to the address and the channel obtained in the previous communication, and the communication safety between the LoRa master machine and the LoRa slave machine is effectively improved.

a generating module 304, configured to generate the configuration information according to the configuration information list, so as to ensure that the generated configuration information is different from the configuration information in the configuration information list.
In an optional embodiment, the communication module 302 is further configured to send a verification communication frame to the LoRa slave; if the verification communication response frame sent by the LoRa slave machine is not received within the preset time, switching to a first channel where the LoRa slave machine is located and sending the configuration information to the LoRa slave machine.
