Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a low-interference wireless communication method, apparatus, computer-readable medium, and device. Background Art

[0002] To ensure stable wireless communication, frequency hopping is often used. This involves switching between the receiver and transmitter using the same frequency. As long as the matching receiver and transmitter maintain the same hopping pattern, they can continuously change the hopping frequency and achieve continuous information transmission, thereby avoiding interference from other signals and improving signal transmission security. However, this method is unable to effectively complete short-term connections between the master and slave nodes in one-to-many or even many-to-many communication scenarios, resulting in long access times and unstable communications.

That is, these functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0032] The flowcharts shown in the accompanying drawings are for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, while others may be combined or partially combined. Therefore, the actual execution order may vary depending on the actual situation.

[0033] Figure 1 A flow chart of a low-interference wireless communication method according to an embodiment of the present application is shown. The method can be applied to a master node, referring to Figure 1 As shown, the method includes at least steps S110 to S160, which are described in detail as follows:

[0034] In step S110 , a first read status instruction of the current master node is broadcast, where the first read status instruction includes a wildcard address of the master node.

[0035] Specifically, the master node may generate a corresponding first read status instruction according to its own wildcard address, and broadcast the first read status instruction for reception by slave nodes around the master node.

[0036] In one example, the first read status instruction may include the master node's signal strength, a control code, and a wildcard address. The control code may be used to indicate the function of the current instruction, such as read status, unlock, or lock. The slave node may perform a corresponding action based on the control code, such as providing feedback of status information, unlocking, or locking.

[0037] In a specific application scenario, the master node and slave node can be a key and a lock capable of wireless communication. When a lock operation is required, such as unlocking or locking, the user can hold the key close to the lock, and the key can broadcast its first read status instruction for the lock to receive. In one example, the master node can also wirelessly power the slave node. When the master node is close to the slave node, it can wirelessly power the slave node to wake it up so that subsequent processing can be carried out.

[0038] In step S120, first status data fed back by at least one slave node according to the wildcard address is received, where the first status data includes a signal strength, a node address, and a default frequency of the slave node.

[0039] In this embodiment, it should be noted that multiple slave nodes may exist in the same space. Therefore, the first read status instruction broadcast by the master node may be received by multiple slave nodes. For example, in the aforementioned application scenario, multiple locks may exist in the same place. In this case, the first read status instruction broadcast by the key may be received by multiple locks. After receiving the first read status instruction, the slave node can feedback corresponding first status data based on the first read status instruction. The first status data includes the slave node's signal strength, node address, and default frequency. The default frequency may be a default communication frequency. The master node can subsequently send data to the slave node based on the default frequency to achieve communication with the slave node.

[0040] In one example, the first read status instruction may include the signal strength, control code, and wildcard address of the master node. After receiving the first read status instruction, the slave node may determine the signal strength of the master node. For example, a master node whose signal strength reaches a certain threshold may be determined as a valid master node. If the signal strength does not reach the certain threshold, the slave node may be determined as an invalid master node and will not respond.

[0041] In addition, the slave node can also make a legitimacy judgment based on the control code and wildcard address to determine whether the master node is legal. Specifically, the slave node can make a legitimacy judgment on the control code and wildcard address in the first read status instruction based on a pre-agreed communication protocol, such as whether the control code is one of the agreed control codes, and whether the wildcard address format complies with the communication protocol, etc.

[0042] Therefore, after judging the signal strength, control code, and wildcard address, if all meet the requirements, the slave node can feedback its first state data to the master node based on the wildcard address. If any one of them does not meet the requirements, no response will be made. This can avoid blind responses from the slave node and waste of resources.

[0043] In one example, the first state data may also include a control code, a slave node frequency hopping identifier, and a slave node state, wherein the control code may be used to indicate the functional purpose of the first state data, and the slave node frequency hopping identifier may be used to indicate whether frequency hopping communication is to be performed for the next frame of data transmission. If frequency hopping is not performed, it indicates that the next frame of data will be communicated at the default frequency, and if frequency hopping is performed, it indicates that frequency hopping communication is required in the next frame. Thus, based on the slave node frequency hopping identifier, the master node can know whether frequency hopping communication is to be performed, thereby ensuring frequency synchronization between the master and slave nodes, ensuring communication between the two, and also preventing interference from other nodes.

[0044] In step S130 , a target slave node is determined from the at least one slave node according to the signal strength of each slave node in the at least one slave node.

[0045] Specifically, the master node may select the slave node with the greatest signal strength from among the slave nodes that have received the first state data as the target slave node, thereby accurately determining the slave node with which communication is required.

[0046] In step S140, a second read status instruction is sent to the target slave node according to the node address and default frequency of the target slave node, so that the target slave node determines the legitimacy of the master node after receiving the second read status instruction.

[0047] In this embodiment, after determining the target slave node, the master node can send a second read status instruction to the node address of the target slave node at the default frequency of the target slave node. After receiving the second read status instruction, the target slave node can verify the legitimacy of the master node based on the second read status instruction.

[0048] In one example, the second read status instruction may include the signal strength of the master node, a control code, and the node address of the target slave node. After receiving the second read status instruction, the target slave node may perform a signal strength determination based on the signal strength and a legitimacy determination based on the control code and the node address of the target slave node. The legitimacy determination based on the node address of the target slave node may include determining whether the target address of the second read status instruction corresponds to the current slave node. If so, this indicates that the second read status instruction was not transmitted in error. Thus, the legitimacy of the master node can be determined.

[0049] In step S150, second status data sent by the target slave node after determining that the master node is legitimate is received. The second status data includes the slave node frequency hopping identifier of the target slave node and the target frequency hopping frequency. The slave node frequency hopping identifier is used to indicate whether frequency hopping communication is performed.

[0050] In this embodiment, after receiving the second state data sent by the target slave node after determining that the master node is legitimate, the master node can determine whether frequency hopping is required for the next frame of communication, as well as the communication frequency after frequency hopping (i.e., the target frequency hopping frequency) based on the slave node frequency hopping identifier and target frequency hopping frequency of the target slave node contained in the second state data. In this way, the master and slave nodes can negotiate the frequency hopping frequency, thereby achieving the purpose of synchronous frequency hopping. Because the target frequency hopping frequency is not the default frequency, even if there are multiple slave nodes, it cannot interfere with the communication between the current master and slave nodes, thereby ensuring the stability of communication between the master and slave nodes.

[0051] In step S160, if the slave node frequency hopping identifier indicates frequency hopping communication, a communication connection is established with the target slave node according to the target frequency hopping frequency.

[0052] In this embodiment, if the slave node frequency hopping identifier indicates that frequency hopping communication is required, then when the master node sends the next frame of data, it can send it according to the target frequency hopping frequency contained in the second state data, and the target slave node can receive the data information sent by the target frequency hopping frequency, thereby realizing the communication connection between the master and slave nodes.

[0053] exist Figure 1 In the illustrated embodiment, a first read status instruction is broadcasted by the current master node, the first read status instruction including the wildcard address of the master node, and first status data is received from at least one slave node based on the wildcard address. The first status data includes the slave node's signal strength, node address, and default frequency. A target slave node is determined based on the signal strength of each of the at least one slave nodes. A second read status instruction is then sent to the target slave node based on the target slave node's node address and default frequency to receive second status data from the target slave node. The second status data includes the target slave node's frequency hopping identifier and target frequency hopping frequency. When frequency hopping communication is required, a communication connection is established with the target slave node based on the target frequency hopping frequency. Thus, the master node can quickly determine the target slave node based on the signal strength and establish a communication connection with the target slave node based on the target frequency hopping frequency. This allows the master node to quickly establish a communication connection with the slave node even in one-to-many or many-to-many communication modes, while preventing interference from other nodes and ensuring stable communication between the master and slave nodes.

[0054] In one embodiment of the present application, determining a target slave node from the at least one slave node according to the signal strength of each slave node in the at least one slave node includes:

[0055] Performing legitimacy verification on each slave node according to the node address and default frequency of the at least one slave node;

[0056] The slave node with the highest signal strength and verified to be legitimate is determined as the target slave node.

[0057] In this embodiment, after receiving the first status data fed back by at least one slave node, the master node can pre-verify the legitimacy of each slave node based on the node address and default frequency of each slave node. For example, the master node can verify whether the node address format of each slave node conforms to a pre-agreed address format, whether the default frequency is a pre-agreed default frequency, etc. Thus, the master node can verify the legitimacy of each slave node based on the information contained in the first status data, thereby avoiding interference from other devices.

[0058] Then, after determining the legitimacy of each slave node, the master node can determine the slave node with the highest signal strength and verified to be legitimate as the target slave node. In this way, the legitimacy and accuracy of the determined target slave node can be guaranteed.

[0059] In one example, the first state data may also include a control code, a slave node frequency hopping identifier, and a slave node status. In addition to the node address and the default frequency, the master node may also perform legitimacy verification on the control code, the slave node frequency hopping identifier, and the node status. Thus, by combining multiple pieces of information for legitimacy verification, the validity of the verification results can be guaranteed.

[0060] based on Figure 1 In the embodiment shown, in one embodiment of the present application, after establishing a communication connection with the target slave node according to the target frequency hopping frequency, the method further includes:

[0061] If it is determined to disconnect the current communication connection, the slave node search is performed again at the default frequency point.

[0062] In this embodiment, the user can determine to disconnect the current communication connection by using a physical button or virtual button set on the master node or by moving the master node away from the slave node. At this time, the master node can continue to broadcast its own first read status instruction at the default frequency, thereby re-searching the slave node. It should be understood that the master and slave nodes that have not yet established a communication connection will broadcast or receive signals at the default frequency. This ensures that the master and slave nodes can achieve preliminary information exchange between them. When it is determined that a communication connection is required, the master and slave nodes will establish a communication connection at the target hopping frequency through frequency hopping negotiation, thereby avoiding interference from other nodes or devices and ensuring the stability of communication between the master and slave nodes.

[0063] Figure 2 A schematic diagram of a low-interference wireless communication method according to another embodiment of the present application is shown. The method can be applied to a slave node, referring to Figure 2 As shown, the method includes at least steps S210 to S250, which are described in detail as follows:

[0064] In step S210, a first read status instruction broadcast by a master node is obtained, where the first read status instruction includes a wildcard address of the master node.

[0065] In this embodiment, when a communication connection is not established, the slave node can receive external information at a default frequency, and if it receives a first read status instruction sent by the master node, it can parse it.

[0066] In step S220, first status data is sent to the master node according to the wildcard address, where the first status data includes the signal strength, node address, and default frequency of the slave node.

[0067] In step S230, if a second read status instruction sent by the master node is received, a target frequency hopping frequency is determined according to a predetermined rule.

[0068] In this embodiment, if the slave node receives a second read status instruction sent by the master node, it means that the master node wants to establish a communication connection with it. At this time, the slave node can determine the target frequency hopping frequency according to the predetermined rules pre-set by the management personnel for use in subsequent communication connections.

[0069] In step S240, second status data is generated according to the target frequency hopping frequency and sent to the master node. The second status data includes a slave node frequency hopping identifier and a target frequency hopping frequency. The slave node frequency hopping identifier is used to indicate whether frequency hopping communication is performed.

[0070] In this embodiment, the slave node can generate second status data based on the generated target frequency hopping frequency and send it to the master node. The second status data can include the slave node frequency hopping identifier and the target frequency hopping frequency, thereby indicating to the master node whether frequency hopping communication is required and the frequency after hopping.

[0071] In step S250, a communication connection is established with the master node according to the target frequency hopping frequency.

[0072] In this embodiment, after feeding back the second status data to the master node, the slave node can receive information from the master node or send information to the master node at the target hopping frequency, thereby establishing a communication connection with the master node and avoiding interference from other nodes.

[0073] It should be noted that Figure 2 For details not disclosed in the illustrated method embodiment, reference may be made to the above-mentioned embodiment of the low-interference wireless communication method applied to the master node of the present application, which will not be described in detail here.

[0074] based on Figure 2 In the embodiment shown, in one embodiment of the present application, the first read status instruction further includes a control code and a signal strength, wherein the control code is used to indicate the communication purpose of the instruction;

[0075] Sending first status data to the master node according to the wildcard address includes:

[0076] When the signal strength reaches a predetermined threshold, verifying the legitimacy of the master node according to the control code and the wildcard address;

[0077] If the verification result is legal, the first status data is sent to the master node according to the wildcard address.

[0078] In one embodiment of the present application, after establishing a communication connection with the master node according to the target frequency hopping frequency, the method further includes:

[0079] If no new communication data is received within a predetermined period of time, the communication connection with the master node is disconnected and the frequency is switched to the default frequency.

[0080] In this embodiment, the slave node can record the time interval for receiving communication data from the master node. If no new communication data sent by the master node is received within a predetermined period of time, the slave node can disconnect the communication connection with the master node and switch to the default frequency to receive the signal again.

[0081] Therefore, the slave node does not need to wait blindly. If no new communication data is received within the predetermined time, the original communication connection will be disconnected and the default frequency will be restored to communicate to receive signals sent by other devices, thereby ensuring the effectiveness of communication.
