[0002] Existing wireless broadcasting technologies, such as FM broadcasting, satellite broadcasting, and IP broadcasting, generally have problems such as limited coverage, low communication efficiency between devices, high cost, and high requirements for the network environment.

At the same time, traditional broadcasting systems rely on a lot of infrastructure construction, which is costly, and the communication efficiency between devices is low, which is prone to signal delay or interruption. Taking IP broadcasting as an example, when the Ethernet is congested, the broadcast signal is difficult to transmit stably, which in turn affects the audio quality. Although satellite signals and FM signals have the advantage of long distance, their bandwidth is low and cannot guarantee the transmission of high-quality audio.

[0038] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In order to solve the problems in the prior art, the present invention proposes a wireless broadcasting method based on Halow-WiFi to achieve efficient transmission of broadcast signals. The wireless broadcasting method based on Halow-WiFi is described below. Figure 1 As shown, including but not limited to the following steps:

[0040] Step 110: Obtain the audio to be played and the target IP address of the target device.

[0041] First, the user can select the audio content to be played through the terminal device (such as a mobile phone, tablet or computer) and specify the target device. The system obtains the audio data through the network interface and obtains the target IP address of the target device corresponding to the audio to be played. The IP address is usually allocated by a DHCP server in the local area network or obtained by static allocation. This step ensures that the system can accurately send the broadcast data to the specified target device.

[0042] Step 120: Generate a broadcast selection protocol according to the target IP address, wherein the broadcast selection protocol includes the target IP address and a local identity.

[0043] After obtaining the IP address of the target device, the system generates a broadcast selection protocol based on the IP address. The content of the broadcast selection protocol includes the target IP address and the local identity (i.e. the ID information of the sending device). The local identity can be used to identify the source of the data in the subsequent communication process to ensure that the broadcast data can be correctly routed to the target device. This protocol helps ensure that the broadcast data can be correctly transmitted and distributed in the Halow-WiFi network.

[0044] Step 130: Pack the broadcast selection protocol and the audio to be played to generate broadcast data to be sent.

[0045] After generating the broadcast selection protocol, the system packages the broadcast selection protocol and the audio data to be played. The packaging method can adopt common data encapsulation technology, such as frame structure or data packet structure. The packaged data is called the broadcast data to be sent, which contains audio data and protocol data to ensure that the data can be correctly transmitted and parsed.

[0046] Step 140: Send the broadcast data to be sent to the first-layer Halow-wifi site device through the Halow-Wifi access point, so that the first-layer Halow-wifi site device performs protocol processing.

[0047] After the broadcast data to be sent is packaged, the system sends the broadcast data to the first-layer Halow-WiFi site device (STA side) through the Halow-WiFi access point (AP side). Halow-WiFi is a low-power wide area network wireless communication technology, which is characterized by a large coverage range and low power consumption. In this step, the Halow-WiFi access point transmits the broadcast data to the first-layer Halow-wifi site devices of the network through a wireless channel, and these devices are responsible for preliminary processing of the received data. This step is the starting stage of the broadcast data entering the Halow-WiFi network.

[0048] Step 150: When there is a target device in the first-layer Halow-wifi site device, the broadcast data to be sent is received through the target device to play the audio to be played.

[0049] When the first-layer Halow-WiFi site device receives the broadcast data to be sent, the system will perform protocol processing on the first-layer Halow-WiFi site device to check whether the device is the target device. Specifically, the first-layer Halow-WiFi site device will determine whether it is the target device based on the target IP address information in the broadcast data. If the first-layer Halow-WiFi site device is confirmed to be the target device, it will receive the broadcast data and extract the audio data from the data packet, and then play the audio data through the built-in audio playback device or the connected external playback device.

[0050] As a further optional embodiment, after the step of sending the broadcast data to be sent to the first-layer Halow-wifi site device through the Halow-Wifi access point for the first-layer Halow-wifi site device to perform protocol processing, the method further includes:

[0051] When there is no target device in the first-layer Halow-wifi site device, the first-layer Halow-wifi site device forwards the to-be-sent broadcast data to the second-layer Halow-wifi site device for protocol processing by the second-layer Halow-wifi site device;

[0052] When there is a target device in the second-layer Halow-wifi site device, the broadcast data to be sent is received through the target device to play the audio to be played.

[0053] In this embodiment, if Figure 2As shown, after the first-layer Halow-WiFi station device (i.e., the first-layer Halow-WiFi STA end in the figure) receives the broadcast data from the Halow-WiFi access point (i.e., the Halow-WiFi AP end in the figure), if it is detected that the first-layer Halow-WiFi station device is not the target device or there is no target device in the network, the first-layer Halow-WiFi station device will forward the data to the next-layer Halow-WiFi station device. The second-layer Halow-WiFi station device (i.e., the second-layer Halow-WiFi STA end in the figure) will continue to receive and process the broadcast data, and this forwarding process can be performed layer by layer until the target device is found or the maximum level of transmission is reached.

[0054] When forwarding to the second-layer Halow-WiFi site device, the device will check whether its network contains the target device based on the target IP address information contained in the broadcast selection protocol. If the target device is detected, the target device will receive the broadcast data, unpack and extract the audio data, and then start playing the audio. Through this recursive forwarding mechanism, the system ensures that even if the target device is not in the first-layer site device, it can still find and play the audio through the network nodes of the next layer.

[0055] The first layer of Halow-WiFi station devices: located in the direct connection layer of the Halow-WiFi access point (AP). These devices have established a direct wireless communication connection with the AP, usually with a higher priority, and are responsible for receiving and processing data transmitted from the AP.

[0056] The second layer of Halow-WiFi station devices: do not have a direct wireless connection with the AP, and usually establish communication with the first layer of station devices. These devices rely on the relay function of the first layer of station devices to receive data.

[0057] By introducing a recursive forwarding mechanism of multiple layers of Halow-WiFi site devices, this embodiment further enhances the reliability of the system, ensuring that during the wireless broadcast process, even if the target device is not in the first layer of site devices, data can be forwarded through other network layers, and finally the audio can be found and successfully played. This hierarchical processing method effectively solves the coverage problem of broadcast data in a large-scale network and increases the availability of the system.

[0058] As a further optional embodiment, after the step of forwarding the to-be-sent broadcast data to the second-layer Halow-wifi site device through the first-layer Halow-wifi site device for the second-layer Halow-wifi site device to perform protocol processing, the method further includes:

[0059] When there is no target device in the second-layer Halow-wifi site device, the broadcast data to be sent is discarded.

[0060] In this embodiment, Figure 2 As shown in the figure, after the broadcast data is forwarded by the first-layer Halow-WiFi site device to the second-layer Halow-WiFi site device and processed by the second-layer device, if it is detected that the target device still does not exist in the network of the device, the system will no longer continue to forward the broadcast data. At this time, the second-layer site device will directly discard the data packet. Through this data discarding mechanism, the system effectively avoids the continued transmission of useless data in the network, reduces the occupation of network resources and redundant forwarding of broadcasts.

[0061] This mechanism is particularly suitable for larger network environments, avoiding unlimited hierarchical recursive forwarding of broadcast data, preventing the increase of bandwidth usage and the accumulation of transmission delays, while also improving the efficiency of the system.

[0062] As a further optional embodiment, the step of sending the broadcast data to be sent to the first-layer Halow-wifi site device through the Halow-Wifi access point specifically includes:

[0063] According to the network topology diagram, determine the first-layer Halow-wifi site equipment;

[0064] The to-be-sent broadcast data is sent to the first-layer Halow-wifi site device through the Halow-Wifi access point.

[0065] By discarding the broadcast data when the target device is not found in the second-layer Halow-WiFi site device, this embodiment significantly improves the system's utilization efficiency of network resources and avoids unnecessary data transmission. When the system cannot find the target device within a reasonable network layer, discarding the data packet in time can not only reduce the network burden, but also ensure that the entire wireless broadcast process is more efficient and flexible.

[0066] As a further optional embodiment, the network topology map is generated based on the survival packets sent by the first layer Halow-wifi site device and the second layer Halow-wifi site device.

[0067] Each Halow-WiFi site device (including the first-layer Halow-WiFi site devices and the second-layer Halow-WiFi site devices) will send survival packets to its surrounding devices at a predetermined time interval. The purpose of these survival packets is to update the connection status and location relationship of each device in the network in real time. By receiving survival packets, the system can automatically generate and update the current network topology map, which records the hierarchical relationship and connection status between Halow-WiFi site devices.

[0068] In the process of generating the network topology diagram, the Halow-WiFi site device follows the following steps:

[0069] Survival packet transmission: The first and second layer Halow-WiFi station devices send survival packets at preset time intervals. The survival packets contain the unique identification of the device and the current network status information.

[0070] Survival packet reception and topology map update: After receiving the survival packet, the adjacent device will update the stored network topology map based on the current network hierarchy and device location. The network status changes of each device (such as device disconnection or movement) can be reflected in the network topology map in real time through the survival packet.

[0071] Dynamic maintenance of topology: When a topology change occurs in the network (for example, some devices go offline or new devices join), the Halow-WiFi site device will detect the change through the survival packet and immediately update its stored network topology. This process can be passed step by step throughout the broadcast network and eventually updated to the Halow-WiFi access point (AP) to ensure that the topology of the entire broadcast network is up to date.

[0072] By generating and maintaining a network topology map based on survival packets, this embodiment ensures the dynamic adaptability of the Halow-WiFi wireless broadcast system. Each site device can automatically sense and update the connection status in the network through the sending and receiving of survival packets, and generate an accurate network topology map in real time. This topology map provides a reference for the effective transmission of broadcast data, enabling the system to optimize data transmission according to the actual network conditions, thereby improving the reliability and flexibility of the entire broadcast network.

[0073] As a further optional embodiment, the survival packet is sent by the first-layer Halow-wifi site device and the second-layer Halow-wifi site device at preset time intervals.

[0074] In this embodiment, in order to ensure the dynamics and real-time performance of the entire network, the site devices in the Halow-WiFi system actively send survival packets at regular time intervals to ensure real-time updating of network topology information.

[0075] The specific implementation method is as follows:

[0076] Survival packet sending mechanism: When the first and second layer Halow-WiFi site devices are running, they actively send survival packets at a predetermined time interval (for example, every 10 seconds or 30 seconds). The survival packet contains the unique identification of the site device, the connection status, and the current layer information. With this information, other devices in the network can identify and record the existence of the device and its location in the network topology.

[0077] Setting of preset time interval: The preset time interval of the system can be configured according to the needs of the actual application scenario. For scenarios with high real-time requirements, the time interval for sending survival packets can be set shorter (for example, every 5 seconds), while for a more stable network environment, the interval can be appropriately extended (for example, every 1 minute). This flexible time interval configuration ensures the adaptability of the system.

[0078] Transmission and reception of survival packets: When a first-layer or second-layer site device sends a survival packet, the surrounding devices receive the packet and record it in their respective network status information. By analyzing the survival packets received regularly, the device can sense the existence of neighboring devices and whether they are working properly. If a survival packet from a device is not received for a period of time, the system can determine that the device may have been offline or malfunctioned, and perform corresponding network updates and adjustments.

[0079] Network status monitoring and topology map update: The regular sending of survival packets enables the Halow-WiFi network to continuously monitor the network status. When the survival packet information of the device changes, the network topology map will also be updated accordingly to reflect the current network connection status and device hierarchy, ensuring the accurate transmission of broadcast data.

[0080] As a further optional embodiment, before the step of obtaining the audio to be played and the target IP address of the target device, the method further includes:

[0081] When the survival packet response is lost, a network change notification packet is generated and sent to the Halow-Wifi access point, so that the Halow-Wifi access point updates the network topology map.

[0082] In this embodiment, a network status monitoring mechanism is further introduced. When a site device in the Halow-WiFi network loses the survival packet response of a device, the system will automatically generate a network change notification packet and update the network topology map in time to ensure that the transmission of broadcast data can adapt to changes in the network structure.

[0083] The specific implementation method is as follows:

[0084] Survival Packet Monitoring: When the system is operating normally, the Halow-WiFi access point continuously monitors the survival packets sent from the first and second layer site devices. If the access point fails to receive the survival packet from a site device within a certain time window, it is considered that the device may be offline or faulty.

[0085] Network change detection: When the access point detects the loss of a survival packet response from a certain site device, the network status change detection mechanism is immediately triggered. At this time, the system automatically generates a network change notification packet to record the relevant information of the offline device, including the device's identity, IP address, and network layer.

[0086] Sending of network change notification packets: The access point broadcasts the generated network change notification packets to other devices in the network to inform them of the disconnection or loss of connection of the device. In this way, all related devices can understand the changes in network topology in real time and avoid continuing to send broadcast data to the invalid device.

[0087] Topology map update: After receiving the network change notification package, the access point will immediately update its internal network topology map, remove offline devices or adjust the network structure. The topology map update ensures that subsequent broadcast data can be transmitted according to the latest network structure, avoiding data transmission delays or failures caused by device disconnection.

[0088] Improve system stability: This coping mechanism after losing the survival packet can significantly improve the stability and adaptability of the Halow-WiFi system. Even if some devices in the network fail or go offline, the system can update the network topology in real time to ensure that the broadcast data can be smoothly transmitted to other valid devices and maintain the normal operation of the entire network.
