[0002] In existing wireless communication networks, information transmission between nodes typically involves a complex encoding and decoding process: the sending node encodes the information and encapsulates it into data packets for transmission over the communication channel; the receiving node receives these data packets and decodes them to determine the information they carry. This method results in a long delay in information transmission because both the encoding and decoding processes at the sending and receiving nodes are time-consuming. Summary of the Invention

[0037] Furthermore, in the description of this application, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0038] The inventors of this application recognized that in existing wireless communication networks, information transmission between nodes generally requires a complex encoding and decoding process, resulting in long information transmission delays. In view of this, this application provides an information transmission method, apparatus, computer-readable storage medium, and electronic device to solve the problem of long information transmission delays in the prior art.

[0039] The basic concept proposed by the inventors of this application is that, during information transmission, there is no need for complex encoding and decoding of information. Instead, different information is represented through different broadcast modes. A broadcast mode refers to the number of communication channels used and / or a specific combination of continuously sending a preset number of data packets in the communication channels. In this way, simple quantitative statistics replace the complex encoding and decoding process, which can effectively reduce the latency of information transmission.

[0040] The method provided in the embodiments of this application can be applied to, for example, Figure 1 The wireless communication network shown includes multiple nodes, such as at least one transmitting node and at least one receiving node.

[0041] The sending and receiving nodes can communicate wirelessly. For example, they can use Bluetooth communication technology. The following embodiments will be described using Bluetooth communication technology as an example.

[0042] The wireless communication network provided in this application embodiment can be applied to any system, such as a lighting system. Taking the wireless communication network provided in this application embodiment as an example of a lighting system, the transmitting node can be a gateway node, and the receiving node can be a lighting node.

[0043] Optionally, both the transmitting node and the receiving node may have a first wireless communication module. This first wireless communication module is used to realize wireless communication between the transmitting node and the receiving node. For example, the first wireless communication module may refer to a Bluetooth mesh network module. The transmitting node and the receiving node form a Bluetooth mesh network and communicate through the Bluetooth mesh network protocol.

[0044] Optionally, taking the sending node as a gateway node as an example, the sending node may also include a second wireless communication module. This second wireless communication module enables wireless communication between the sending node and the server. For example, the second wireless communication module could be a cellular communication network module (equipped with a Subscriber Identity Module, SIM card). Then, the gateway node and the server form a cellular communication network, and the gateway node can receive target information from the server through the second wireless communication module. Examples include the following lighting switch commands, lighting off commands, and dimming commands.

[0045] For ease of understanding, this application will describe the sending and receiving nodes in detail separately. It is important to note that the role of any node in a wireless communication network during information transmission can change; that is, in one information transmission, the node can act as a sending node, while in another, it can act as a receiving node. For example, when a gateway node sends control commands to a lighting node, the gateway node can act as the sending node, and the lighting node can act as the receiving node; conversely, when the lighting node uploads various status information and alarms to the gateway node, the lighting node can act as the sending node, and the gateway node can act as the receiving node.

[0046] The following describes an embodiment of an information transmission method in this application, taking the transmitting node in a wireless communication network as the execution subject. Figure 2 As shown, the method may include: Step S201: Obtain the first target information.

[0047] The first target information can be any target information to be transmitted, and can be flexibly set according to the actual application scenario. This application embodiment does not make specific limitations on this.

[0048] As an example, in a wireless communication network applied to a lighting system, the target information transmitted can be the configuration and / or control commands of the lighting system. For instance, the lighting system configuration includes, but is not limited to, the configuration of voltage, current, and power; the control commands include, but are not limited to, lighting on commands, lighting off commands, and dimming commands. It is understood that a lighting on command instructs the lighting fixtures to be turned on, a lighting off command instructs the lighting fixtures to be turned off, and a dimming command instructs the adjustment of the lighting intensity.

[0049] It should be noted that the target information listed above is merely an example. In actual application scenarios, the target information transmitted can also be node fault information, grouping information, or other information. These types of information share the common characteristic of being relatively simple, making them easy to represent using different broadcast modes. This reduces information transmission latency, allowing receiving nodes to respond quickly.

[0050] Step S202: Determine the target broadcast mode corresponding to the first target information from at least one broadcast mode.

[0051] Different broadcast modes represent different target information, and different broadcast modes correspond to different channel coding strategies. The channel coding strategy is determined based on the number of communication channels used by the broadcast mode and / or a specific combination of continuously sending a preset number of data packets in the communication channel.

[0052] The wireless communication network in this application embodiment may include, but is not limited to, Bluetooth mesh network, Zigbee network, etc. For different wireless communication networks, information can be transmitted through different communication channels.

[0053] Taking Bluetooth mesh networks as an example, such as Figure 2 As shown, information can be transmitted through three Bluetooth broadcast channels: channel 37 (center frequency 2.402 GHz), channel 38 (center frequency 2.426 GHz), and channel 39 (center frequency 2.480 GHz). To improve the success rate of the receiving node, the sending node can broadcast the information multiple times (e.g., at least three times), with a preset advertising interval between two consecutive broadcasts. Correspondingly, the receiving node can scan the three Bluetooth broadcast channels sequentially at preset scan intervals, i.e., according to preset scan windows. For example, it scans channel 37 in the first scan interval window, channel 38 in the second scan interval window, channel 39 in the third scan interval window, channel 37 in the fourth scan interval window, channel 38 in the fifth scan interval window, and so on.

[0054] The number of data packets continuously transmitted in channel 37 will be denoted as Num here. 37 The number of data packets continuously transmitted in channel 38 is denoted as Num. 38 The number of data packets continuously transmitted in channel 37 is denoted as Num. 39 , where Num 37 Num 38Num 39 All values ​​are greater than or equal to 0. When the number of consecutively transmitted data packets in a channel is 0, it means that the channel is not being used for information transmission. 37 Num 38 Num 39 Different combinations of values ​​can form different broadcast patterns, each used to represent different target information.

[0055] The specific correspondence between the broadcast mode and the target information can be flexibly set according to the actual situation, and this application embodiment does not impose specific limitations on this.

[0056] In this embodiment, a lighting off command and a lighting on command can be represented by sending a preset number of data packets according to a first preset rule in at least one communication channel. A dimming command can be represented by sending a preset number of data packets according to a second preset rule in at least one communication channel.

[0057] The following example uses the first preset rule: continuously sending a first number of data packets to represent a lighting on command, and continuously sending a second number of data packets to represent a lighting off command.

[0058] In one specific implementation of this application, when the first target information is a lighting turn-on command, the target broadcast mode can be determined to be continuously sending a first number of data packets in any communication channel; when the first target information is a lighting turn-off command, the target broadcast mode can be determined to be continuously sending a second number of data packets in any communication channel. The second number is different from the first number, and their specific values ​​can be flexibly set according to actual conditions. This application does not specifically limit this. As an example, the first number can be set to 3, and the second number can be set to 4.

[0059] Taking Bluetooth mesh networks as an example, such as Figure 3 As shown, sending three consecutive data packets in any one of the three Bluetooth broadcast channels (channels 37, 38, and 39) indicates a lighting-on command. Figure 4 As shown, sending four data packets consecutively in any one of the three Bluetooth broadcast channels, channel 37, channel 38, and channel 39, represents a lighting off command.

[0060] In one specific implementation of this application, when the first target information is a lighting turn-on command, the target broadcast mode can be determined as continuously sending a first number of first data packets in any communication channel. In another specific implementation of this application, when the first target information is a lighting turn-off command, the target broadcast mode can be determined as continuously sending a first number of second data packets in any communication channel. The first data packets and the second data packets are different.

[0061] For example, the first data packet carries first indication information or a first flag, and the second data packet carries second indication information or a second flag. The first flag or first indication information indicates that the lighting is on. The second indication information or second flag indicates that the lighting is off. For example, the first indication information or first flag can be 0, and the second indication information or second flag can be 1.

[0062] Of course, the first preset rule in this application embodiment can also refer to: continuously sending N data packets in a specific communication channel to represent a lighting on command, and continuously sending N data packets in another specific communication channel to represent a lighting off command. Taking N=4 as an example, for instance, continuously sending 4 data packets in channel 37 to represent a lighting on command, and continuously sending 4 data packets in channel 38 to represent a lighting off command. Alternatively, continuously sending 4 data packets in channels 37 and 38 respectively to represent a lighting on command, and continuously sending 4 data packets in channels 38 and 39 respectively to represent a lighting off command.

[0063] The first preset rule in this application embodiment can also refer to: continuously sending N consecutive data packets in a communication channel to represent a lighting on command, and intermittently sending N data packets in a communication channel according to a preset period to represent a lighting off command. For example, continuously sending 4 data packets in channel 37 to represent a lighting on command, and intermittently sending 3 data packets in channel 38 to represent a lighting off command.

[0064] The following example uses the second preset rule: continuously sending a first number of data packets in multiple communication channels to represent a lighting turn-on command, and continuously sending a second number of data packets in multiple communication channels to represent a lighting turn-off command.

[0065] In one specific implementation of this application, when the first target information is a dimming command, the target broadcast mode can be determined as continuously sending a third number of data packets in a first communication channel, continuously sending a fourth number of data packets in a second communication channel, and continuously sending a fifth number of data packets in a third communication channel. The third, fourth, and fifth numbers are combinations of quantities corresponding to the dimming level indicated in the dimming command. The third, fourth, and fifth numbers can be the same or different; for example, they can increase or decrease according to a preset amount of change. Different dimming levels can correspond to different combinations of quantities, and the specific correspondence between dimming levels and quantity combinations can be flexibly set according to actual conditions. This application does not specifically limit this.

[0066] Taking Bluetooth mesh networks as an example, such as Figure 5 As shown, continuously transmitting one data packet in channel 37, two data packets in channel 38, and three data packets in channel 39 represents 75% dimming. Similarly, continuously transmitting two data packets in channel 37, one data packet in channel 38, and two data packets in channel 39 represents 50% dimming. Continuously transmitting three data packets in channel 37, two data packets in channel 38, and one data packet in channel 39 represents 25% dimming, and so on.

[0067] In one specific implementation of this application, when the first target information is a dimming command, the target broadcast mode can be determined to be the continuous transmission of a first number of combined data packets across multiple communication channels to represent the dimming command. Different dimming levels correspond to different data packets.

[0068] For example, a data packet with 75% dimming carries a third indication or a third marker, a data packet with 50% dimming carries a fourth indication or a fourth marker, and a data packet with 25% dimming carries a fifth indication or a fifth marker. The third marker or third indication indicates 75% dimming, the fourth marker or fourth indication indicates 50% dimming, and the fifth marker or fifth indication indicates 25% dimming. For example, the third indication or third marker could be 75, the fourth marker or fourth indication could be 50, and the fifth marker or fifth indication could be 25.

[0069] Of course, the second preset rule in this application embodiment can also refer to: continuously sending a first combination of data packets in a specific communication channel group to represent a lighting dimming command. Different dimming levels correspond to different communication channel groups. For example, a communication channel group includes two communication channels, and the first combination consists of 3 data packets and 4 data packets in the two communication channels respectively. Continuously sending 3 data packets in channel 37 and 4 data packets in channel 38 represents 75% dimming; continuously sending 3 data packets in channel 37 and 4 data packets in channel 39 represents 50% dimming; continuously sending 3 data packets in channel 38 and 4 data packets in channel 39 represents 25% dimming.

[0070] Step S203: According to the target broadcast mode, continuously send a preset number of data packets in the communication channel corresponding to the target broadcast mode.

[0071] Since this application embodiment replaces the complex encoding and decoding process with simple quantity statistics, it focuses on the number of data packets in the communication channel and does not care about the specific data of the data packets. Therefore, in a specific implementation of this application embodiment, the data in the data packets can be set to empty to shorten the length of the data packets, thereby reducing the probability of data packet collisions and improving its anti-interference ability.

[0072] Corresponding to the aforementioned sending node, the following will describe an embodiment of an information transmission method in this application, with the receiving node in a wireless communication network as the executing entity. Figure 7 As shown, the method may include: Step S701: Receive data packets from at least one communication channel.

[0073] Step S702: Determine the number of data packets continuously received in the communication channel.

[0074] Step S703: Determine the first target information corresponding to the target broadcast mode based on the number of data packets continuously received in the communication channel.

[0075] Different broadcast modes represent different target information, and each broadcast mode corresponds to a different channel coding strategy. The channel coding strategy is determined based on the number of communication channels used by the broadcast mode and / or a specific combination of continuously sending a preset number of data packets in the communication channels. As an example, in a wireless communication network applied to a lighting system, the target information transmitted can be the configuration and / or control commands of the lighting system.

[0076] In one specific implementation of the embodiments of this application, corresponding to Figure 4In the broadcast mode shown, if the number of data packets continuously received in any communication channel is a first quantity, the first target information can be determined to be a lighting turn-on command; corresponding to Figure 5 In the broadcast mode shown, if the number of data packets continuously received in any communication channel is the second number, the first target information can be determined to be a lighting off command. Here, the second number differs from the first number.

[0077] In one specific implementation of the embodiments of this application, corresponding to Figure 6 In the broadcast mode shown, if a third number of consecutive data packets are received continuously in the first communication channel, a fourth number of consecutive data packets are received continuously in the second communication channel, and a fifth number of consecutive data packets are received continuously in the third communication channel, the first target information can be determined to be a dimming command. Here, the third, fourth, and fifth numbers are combinations of quantities corresponding to the dimming levels indicated in the dimming command; different dimming levels correspond to different combinations of quantities.

[0078] It's easy to understand that the process at the receiving node is the reverse of that at the sending node. That is, the sending node performs a mapping from target information to broadcast mode, while the receiving node performs a mapping from broadcast mode to target information. Both nodes share the same specific correspondence between broadcast mode and target information. Details not elaborated on in the receiving node section can be found in the aforementioned description of the sending node, and will not be repeated here.

[0079] Combining the aforementioned information transmission methods applied to the sending node and the receiving node respectively, the following will focus on... Figure 1 The Bluetooth mesh network used in a lighting system is shown as an example to describe the complete information transmission process in detail.

[0080] When control of the lighting system is required, control commands can be sent from the server to the gateway node. Upon receiving a control command, the gateway node can determine the corresponding broadcast mode based on the correspondence between broadcast modes and control commands, and then send data packets according to that broadcast mode. For example, sending three consecutive data packets in any one of the three Bluetooth broadcast channels (channels 37, 38, and 39) represents a lighting-on command; sending four consecutive data packets in any one of these channels represents a lighting-off command; sending one consecutive data packet in channel 37, two consecutive data packets in channel 38, and three consecutive data packets in channel 39 represents 75% dimming; sending two consecutive data packets in channel 37, one consecutive data packet in channel 38, and two consecutive data packets in channel 39 represents 50% dimming; sending three consecutive data packets in channel 37, two consecutive data packets in channel 38, and one consecutive data packet in channel 39 represents 25% dimming, and so on.

[0081] Other nodes can scan the Bluetooth broadcast channel and count the number of consecutive data packets detected. If the number of consecutive data packets matches a certain broadcast pattern, the corresponding control command can be determined based on the correspondence between the broadcast pattern and the control command. The nodes can then execute actions such as turning lights on, off, or dimming according to this control command. Simultaneously, the control command can be relayed throughout the network according to this broadcast pattern.
