[0001] The present application relates to the field of communication technology, and in particular to a multi-hop network anti-crosstalk configuration method and system, infrared equipment, and node equipment. Background Art

[0002] The ISM band (Industrial Scientific Medical Band) is a spectrum region defined by the International Telecommunication Union - Radiocommunication Sector (ITU-R) for use by major organizations in the three fields of industry, science, and medicine. 2.4 GHz mesh networks utilize the 2.4 GHz scientific research band within the ISM (2.400 to 2.4835 GHz). This band is also widely used for various wireless network technologies, including wireless LANs, Bluetooth, and ad hoc wireless communication technology (ZigBee).

[0003] In a 2.4GHz mesh network (a multi-node, decentralized, self-organizing wireless multi-hop communication network), data exchange between devices is sent and received in the form of broadcast packets through wireless channels in the 2.4GHz frequency band.

[0004] Currently, mesh node devices produced by the same manufacturer have the same factory settings, which leads to signal crosstalk when the terminal products are used by different customers in adjacent locations, affecting the customer's usage and experience.

[0005] The existing method for preventing crosstalk is to set different factory settings for different customers. However, this method requires manufacturers to store and maintain the factory configuration information of each customer's device. When a customer adds or replaces a node device, the new device must be set to the same factory settings as the previous device. This is inflexible in implementation and increases maintenance costs and difficulties for manufacturers.

[0006] Based on this, the present application provides a new method for preventing crosstalk between devices. Summary of the Invention

[0014] Acquire second configuration information stored in the flash memory of the node device itself;

[0015] When the second configuration information is different from the first configuration information, the first configuration information is used to replace the second configuration information, so that the node device performs multi-hop communication according to the newly stored first configuration information.

[0031] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0032] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that, in the absence of conflict, the features in the following embodiments and embodiments can be combined with each other. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative work are within the scope of protection of this application.

[0033] It should be noted that various aspects of the embodiments within the scope of the appended claims are described below. It should be apparent that the aspects described herein can be embodied in a wide variety of forms, and any specific structure and / or function described herein is merely illustrative. Based on this application, it should be understood by those skilled in the art that an aspect described herein can be implemented independently of any other aspect, and two or more of these aspects can be combined in various ways. For example, any number and aspect described herein can be used to implement an apparatus and / or practice a method. In addition, other structures and / or functionalities other than one or more of the aspects described herein can be used to implement this apparatus and / or practice this method.

[0034] It should also be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The illustrations only show components related to the present application and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0035] Additionally, in the following description, specific details are provided to provide a thorough understanding of the examples, however, one skilled in the art will appreciate that the examples can be practiced without these specific details.

[0036] In a 2.4GHz mesh network, data exchange between devices occurs via broadcast packets sent and received over a 2.4GHz wireless channel. To ensure that transmitted data is received by other devices in the mesh network, two conditions must be met: first, the sending and receiving devices use the same 2.4GHz wireless channel; and second, the sending device's Tx ADDR and the receiving device's Rx ADDR must match.

[0037] Usually, mesh node devices produced by the same manufacturer can be configured with unified factory settings to ensure that the products meet the above-mentioned usage conditions. However, such factory settings may cause signal crosstalk between the node devices used by different customers in adjacent locations when the terminal products are used.

[0038] To solve the crosstalk problem, the existing solution is for the manufacturer to set different Tx / Rx ADDRs or wireless channel numbers for different customers, that is, the manufacturer pre-sets different factory parameters.

[0039] In view of this, the inventors have found through research and improvement exploration that:

[0040] On the one hand, the manufacturer maintains data such as Tx / Rx addresses and wireless channel numbers used by customers. Once the number of node devices and users increases, the manufacturer's maintenance workload becomes very heavy, making it difficult to promote in actual applications.

[0041] Secondly, when customers subsequently add or replace node devices, especially if the node devices are from a different manufacturer, the new devices need to be configured with the previously retained Tx / Rx addresses and wireless channel numbers. The cost and difficulty of maintaining this data for the manufacturer are beyond imagination.

[0042] Third, a workaround is for the manufacturer to come to each customer to configure the system individually, but this configuration method increases the burden on the manufacturer and also increases the risk of incorrect configuration.

[0043] Based on this, the embodiment of this specification proposes a new solution to prevent crosstalk between devices: Figure 1 As shown, in the initial stage of use by the terminal customer, user A uses infrared device 1 to randomly generate configuration information 1, and uses it to configure each node device in the mesh network. User B uses infrared device 2 to randomly generate configuration information 2, and uses it to configure each node device in the mesh network.

[0044] On the one hand, since the configuration information is generated randomly by different infrared devices, even if users in adjacent locations use infrared devices to configure node devices, the possibility of randomly generating the same configuration information is very low, which can fundamentally avoid the crosstalk problem caused by the node devices of users in adjacent locations using the same communication address and wireless channel; on the other hand, since infrared devices are used to configure node devices, they are limited by the infrared communication range. Even users in adjacent locations will not affect the normal operation of other users' node devices during configuration, further eliminating the occurrence of crosstalk problems; on the third hand, infrared configuration work can be completed anytime and anywhere by users themselves using infrared devices that can configure node devices. There is no need for excessive involvement from manufacturers, and the addition and replacement of new node devices can also be completed by users alone, which is very convenient for the configuration and use of node devices.

[0045] In summary, configuring node devices through infrared devices allows even adjacent customers to use different configuration information for their node devices. This prevents crosstalk between node devices of different users in adjacent areas, improving overall user experience and satisfaction. Furthermore, the simplicity of node device configuration and use greatly facilitates the deployment and widespread application of multi-hop networks (mesh networks) in various scenarios.

[0046] It should be noted that if the configuration information stored in the flash memory of the node device is inconsistent with the parsed configuration information sent by the infrared device, the node device will update and save the parsed configuration information in the flash memory.

[0047] Therefore, by sending configuration information through infrared signals, the node device updates its own configuration information according to the received configuration, solving the signal crosstalk problem between different user node devices in the area, thereby ensuring network stability and communication security. At the same time, it simplifies the device configuration process, making operation simpler and implementation more flexible, reducing the manufacturer's maintenance costs and significantly improving the user's overall experience and satisfaction.

[0048] The following describes the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0049] like Figure 2 As shown, an embodiment of this specification provides a multi-hop network anti-crosstalk configuration method, which is applied to infrared devices. The multi-hop network anti-crosstalk configuration method includes: step S101 to step S102.

[0050] Step S101, read first configuration information; wherein, the first configuration information includes a first communication address and / or a first wireless channel number required for a node device in a multi-hop network to perform multi-hop communication, and the first configuration information is randomly generated information.

[0051] Specifically, after the infrared device is powered on and started, the first configuration information in the flash memory is read, such as the first communication address (Tx / Rx ADDR) and the first wireless channel number (N).

[0052] Step S102: Send the first configuration information as prefix information to the node device via an infrared signal, so that the node device updates its own first communication address and first wireless channel number after receiving the prefix information.

[0053] Specifically, the infrared device operates on the node device, uses the read first communication address (Tx / RxADDR) and first wireless channel number (N) as prefix information, combines it with other data into a complete infrared data packet, and sends it to the node device via an infrared signal to update the first communication address and first wireless channel number of the node device, thereby enabling the node device to dynamically update its communication configuration and ensure stable communication between devices in the 2.4G mesh network.

[0054] like Figure 3 As shown, in one embodiment, the prefix information is added to the grouping instruction, and the grouping instruction is sent to the node device via an infrared signal, so that after the node device receives the grouping instruction, the multi-hop communication grouping configuration is completed according to the prefix information, and centralized management and control can be performed for different groups, such as setting specific parameters, performing specific operations, etc.

[0055] In one embodiment, the prefix information is added to a control instruction, and the control instruction is sent to a node device via an infrared signal, so that the node device performs data transmission and reception control of multi-hop communication according to the prefix information after receiving the control instruction.

[0056] In combination with the above embodiments, the infrared device can control a single node device or a group of node devices.

[0057] For example, suppose there are three node devices: light bulb A, smart curtain B, and light bulb C. Light bulb A and smart curtain B can be divided into group X and light bulb C into group Y using an infrared device. When the infrared device controls light bulb A (turns on), smart curtain B automatically closes, but light bulb C remains unlit because it belongs to a different group.

[0058] For example, suppose there are three node devices: light A and smart curtain B are in group X, and light C is in group Y. Now, light C is assigned to group X and turned on through infrared equipment. At this time, smart curtain B will automatically close, and light A will be turned on at the same time.

[0059] In one embodiment, the first configuration information is displayed.

[0060] Can be used to replace new infrared devices.

[0061] Specifically, the infrared device has a display function and can display the first configuration information. The user can update the configuration information displayed on the original infrared device to the new infrared device, which is convenient for the user to replace the new infrared device.

[0062] You can also associate applications.

[0063] Specifically, the user inputs the configuration information of the infrared device on the corresponding applet or application, and can use the applet or application to replace the original infrared device, thereby improving the user experience and convenience of operation.

[0064] In one embodiment, a first identification value is stored in a flash memory of the infrared device to identify the first configuration information.

[0065] Specifically, the first identification value can determine the state of the infrared device, such as whether it is powered on for the first time, to ensure that operations are performed according to the correct process during startup.

[0066] In combination with the above embodiments, Figure 3 As shown, when the infrared device is powered on, the data in the flash memory is read to determine whether the first identification value (Magic Number) exists. If not, it indicates that the infrared device is initialized and the first configuration information is randomly generated. These settings are saved in the flash memory, and the Magic Number is set at the same time so that the remote control knows that initialization has been performed the next time it is powered on, which simplifies user operations and improves user experience. If the first identification value (Magic Number) exists, the corresponding first configuration information is obtained according to the first identification value (Magic Number).

[0067] The first configuration information can introduce random factors to increase randomness and reduce the likelihood of generating identical configuration information. For example, the first configuration information can include information such as location, timestamp, and device serial number to increase its uniqueness and randomness. This allows for non-interference signal transmission between node devices of different users in adjacent areas, ensuring the stability and reliability of network communications.

[0068] In addition, you can choose to randomly generate only the first communication address (Tx / Rx ADDR);

[0069] or randomly changing the character data at a designated position in the first communication address data;

[0070] or randomly generate a first wireless channel number (N);

[0071] or randomly changing the character data at a specified position in the first wireless channel number data;

[0072] Alternatively, a set of data is randomly generated and used as the first communication address (Tx / Rx ADDR) and the first wireless channel number (N).

[0073] For corresponding reference, see Figure 4 , is a flow chart of another multi-hop network anti-crosstalk configuration method provided by an embodiment of this specification. The difference between the method provided by this embodiment and the above embodiment is that the method provided by this embodiment is applied to a node device. Figure 4 As shown, the multi-hop network anti-crosstalk configuration method mainly includes: steps S701 to S703.

[0074] Step S701: Receive an infrared signal and parse out prefix information, wherein the infrared signal is transmitted by an infrared device, and the prefix information in the infrared signal includes first configuration information, and the first configuration information includes a first communication address and a first wireless channel number required for the node device to perform multi-hop communication.

[0075] Specifically, if Figure 5 As shown, a node device receives an infrared signal transmitted by an infrared device and parses the prefix information. The prefix information contains the first configuration information required for the node device to conduct multi-hop communication, including the first communication address (Tx / Rx ADDR) and the first wireless channel number (N). The first communication address (Tx / Rx ADDR) is used to uniquely identify the node device's location in the network, while the first wireless channel number (N) determines the wireless channel used for communication between node devices. By parsing the prefix information in the infrared signal, the node device can obtain the initial configuration information, thereby correctly setting the communication parameters and ensuring that the device can participate in multi-hop communication normally.

[0076] Step S702: Acquire the second configuration information stored in the flash memory of the node device itself.

[0077] In combination with the above embodiment, the node device reads the second configuration information (ie, the communication address Tx / Rx ADDR and the wireless channel number N) stored in its own flash memory.

[0078] Step S703: When the second configuration information is different from the first configuration information, the first configuration information replaces the second configuration information, so that the node device performs multi-hop communication according to the newly stored first configuration information.

[0079] In combination with the above embodiment, the obtained second configuration information is compared with the parsed prefix information (i.e., the first configuration information) to determine whether they are consistent. If the two are inconsistent, the received prefix information is updated to the flash memory (Flash) of the node device. If the two are consistent, no changes are made, and subsequent data packets sent and received use the updated configuration information.

[0080] In one embodiment, if Figure 5 As shown, the infrared data packet received by the node device contains the group configuration instruction or control instruction signal of the prefix information, parses the infrared data, obtains the prefix information and group or control command, and the node device completes the multi-hop communication group configuration or transceiver control according to the prefix information.

[0081] The embodiment of this specification also provides an infrared device that can be used to perform Figure 2 The implementation principles and technical effects of the steps in the method embodiment shown are similar and will not be repeated here.

[0082] The embodiment of this specification also provides a node device that can be used to execute Figure 4 The implementation principles and technical effects of the steps in the method embodiment shown are similar and will not be repeated here.

[0083] In one embodiment, the node device is a smart home device, such as Figure 6 The smart home device includes a fully integrated system on chip (SoC chip), wherein the SoC chip includes a controller, a radar sensor, a low-power Bluetooth module and an infrared receiving circuit. The controller is used to control the infrared receiving circuit to receive infrared signals to complete node device configuration. The controller is also used to control the radar sensor to sense moving targets around the smart home device through microwave signals, and control the low-power Bluetooth module to perform multi-hop communication based on the sensing results, thereby realizing intelligent linkage control between smart home devices.

[0084] Specifically, the configuration information is sent via the infrared device, and the node device updates its own configuration information according to the received configuration, ensuring that the communication parameters between the node devices of the same user are consistent.

[0085] A node device is a device used in a multi-hop network. It is a smart home system composed of any one of the following home appliances or a combination of two or more home appliances: smart lights, refrigerators, air conditioners, curtains, etc.

[0086] Node devices can perform corresponding operations according to the rules set by users. At the same time, node devices can also sense and control each other, thereby realizing intelligent control and decision-making.

[0087] For example, suppose node device 1 is lamp A and node device 2 is lamp B. When node device 1 senses someone approaching, it lights up and sends a signal notification to other node devices. When node device 2 senses that node device 1 is lit, it will also light up.

[0088] For example, suppose there are three node devices: light bulb A, air conditioner B, and light bulb C. Light bulb A and air conditioner B are in group X, and light bulb C is in group Y. When light bulb A senses someone approaching, it automatically lights up and sends a signal notification to other node devices. At this time, air conditioner B will start up after sensing that light bulb A is lit, but light bulb C will not light up because it belongs to a different group and is therefore not affected by light bulb A's signal.

[0089] For example, suppose node device 1 is lamp A and node device 2 is lamp B. When the surrounding environment becomes darker, node device 1 starts working and can send a signal to notify other node devices. After node device 2 senses the working status of node device 1, it also starts working to respond to environmental changes.

[0090] For example, the user sets a time for a node device to start working / stop working. When the set time is reached, the node device will start / stop accordingly.

[0091] For another example, assuming that node device 1 is a light and node device 2 is a TV, the user can use an infrared device to control node device 1 to turn off and send a signal notification to other node devices at the same time. When node device 2 senses that node device 1 is turned off, it will automatically turn on.

[0092] In short, node devices based on dual-mode SoC sensor chips can autonomously adjust and coordinate according to set rules or infrared device control, improving the overall efficiency and intelligence level of the system.

[0093] The embodiment of this specification also provides a multi-hop network anti-crosstalk configuration system, which includes: an infrared device and a node device;

[0094] The infrared device is configured to use the first configuration information as prefix information of the infrared signal to send the infrared signal to a node device in the multi-hop network; wherein the first configuration information is randomly generated and includes a first communication address and / or a first wireless channel;

[0095] The node device is used to receive infrared signals and parse out prefix information, and when the first configuration information in the prefix information is inconsistent with the second configuration information stored in its own flash memory, the first configuration information replaces the second configuration information, so that the node device performs multi-hop communication according to the newly stored first configuration information.

[0096] The multi-hop network anti-crosstalk configuration system of the embodiment of this specification can be used to perform Figure 2 and Figure 4 The implementation principles and technical effects of the steps in the method embodiment shown are similar and will not be repeated here.

[0097] In this specification, the same or similar parts between the various embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the embodiments described later, the description is relatively simple, and the relevant parts can be referred to the partial description of the previous embodiments.

[0098] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
