[0041] Embodiment 1

[0042] In the first embodiment of the present invention, see Figure 1 , a wireless communication method for the Internet of Things based on the Star Flash protocol, comprising the following steps S01 to S04:

[0043] S01, deploy multiple wireless communication nodes in a wide area or a long-distance path to ensure that the distribution distance between any two of the wireless communication nodes does not exceed 200 meters when there are no obstacles;

[0044] See also Figure 2 and Figure 3 Specifically, in a wide area or on a long-distance path, wireless communication modules are arbitrarily distributed with a spacing less than 200 meters without obstacles.

[0045] S02, selecting one or more of the wireless communication nodes as gateway nodes, wherein the gateway nodes have the ability to communicate with any other wireless communication nodes;

[0046] Specifically, after designating one or more wireless modules as gateway nodes, any wireless module can communicate with the gateway node.

[0047] S03, assigning a unique identification code to each wireless communication node, and grouping the nodes according to the identification code, so that the wireless communication nodes with the same identification code can automatically build a tree network structure under the guidance of the designated gateway node;

[0048] Please refer to 4. Specifically, each wireless module can be assigned an identification code for grouping. After the wireless modules with the same identification code are designated as gateway nodes, they can form a tree-like self-organizing network.

[0049] S04, using the wireless communication node to intelligently select the other end to connect based on the signal strength and the current network topology. After the connection is established, the gateway node obtains and records the MAC addresses of all online wireless communication nodes, and uses the MAC addresses for data access and control.

[0050] Specifically, the wireless module can comprehensively select the opposite end to connect to based on the signal strength and topology structure. After the connection is completed, the gateway node can obtain the MAC addresses of all modules on the network and access data through the MAC addresses.

[0051] Furthermore, the wireless communication node can automatically search for network equipment to form a network after the signal is disconnected due to movement or occlusion, so as to achieve automatic network repair. The wireless module can automatically search for network equipment to form a network after the signal is disconnected due to movement or occlusion, so that the entire network can be automatically repaired.

[0052] Furthermore, the wireless communication node implements hop-point cascading technology to achieve wide-area coverage of communication; wherein, after the gateway node sends data to the designated wireless module, the wireless module on each path will parse the target address of the data packet and automatically forward the address of the next path. The wireless module implements hop-point cascading technology to achieve wide-area coverage of communication, wherein, after the gateway node sends data to the designated wireless module, the module on each path will parse the target address of the data packet and automatically forward the address of the next path.

[0053] Furthermore, after the step of grouping by the identification code, the method further includes:

[0054] The wireless communication module is configured with a transparent transmission address according to actual needs, wherein the transparent transmission address is designed as an address specifically used for data transmission in the network, which can ensure that data is transparently transmitted between various nodes of the Internet of Things without any processing or format conversion.

[0055] Furthermore, the grouping of the wireless communication nodes, the configuration of the transparent transmission address of the line communication module and the selection of the gateway node can all be performed on one of the wireless communication nodes.

[0056] In this embodiment, the IoT wireless communication method based on the Star Flash protocol can be used for centralized control of factory equipment, sensor communication, mobile robot communication within the factory, outdoor road parking lock control, charging piles, street light control, building IoT equipment communication and other needs.

[0057] Use scenarios include: centralized access to parking lock gateways. Centralized access to charging pile gateways. Remote connection of energy storage and electric meters. Remote control of various access control machines. Centralized access to factory equipment gateways. Mobile robot communication within the field. UAV hop communication. Other occasions suitable for long-distance hop communication.

[0058] The following is a detailed description of the centralized network access of the parking lock gateway:

[0059] 1. Module grouping and numbering (parking lock grouping);

[0060] In the scenario where the parking lock gateway is centrally connected to the network, it is first necessary to treat each parking lock as a module that needs to be networked and group them. The grouping here may be based on geographical location (such as different parking areas), functional requirements (such as temporary parking, long-term rental, etc.) or communication requirements (such as signal strength, communication protocol, etc.). After the grouping is completed, the same number needs to be set for each parking lock. This number is used to identify and recognize each parking lock in the network to ensure that they can be properly managed and controlled.

[0061] 2. Set the root node (gateway setting);

[0062] Next, you need to set up a gateway as the core part of the network. The gateway plays a vital role here. It is responsible for receiving data from each parking lock and forwarding this data to the designated server or cloud platform. At the same time, the gateway is also responsible for sending control instructions to the parking lock, such as opening and closing the parking lock. When selecting a gateway, you need to consider its performance parameters such as processing power, storage capacity, and communication bandwidth to ensure that it can meet the needs of the network.

[0063] 3. Set the transparent transmission address (data transmission configuration)

[0064] In the scenario where the parking lock gateway is centrally connected to the network, the setting of the transparent address is crucial for the correct transmission of data. The transparent address allows data to be transmitted transparently between the gateway and the parking lock without any processing or conversion. This means that the gateway can receive raw data from the parking lock and forward it directly to the server or cloud platform without any modification to the data. At the same time, the server or cloud platform can also send control instructions to the gateway, and the gateway forwards these instructions directly to the specified parking lock without any interpretation or conversion.

[0065] 4. Operation nodes (network management and configuration);

[0066] Finally, all these steps can be performed on an operation node, which may be the gateway itself, or a server or computer connected to the gateway. Through the operation node, users can easily configure and manage the network, such as setting the grouping and numbering of parking locks, selecting gateways, configuring transparent addresses, etc. At the same time, users can also monitor the status and performance of the network through the operation node, such as checking the usage of parking locks, communication status, etc. If a fault or abnormal situation occurs, users can also perform troubleshooting and recovery operations through the operation node.

[0067] In the actual centralized network access scenario of parking lock gateways, these steps together constitute the basic framework and process of network deployment. Through reasonable grouping, setting gateways, configuring transparent addresses and operating nodes, centralized management and control of parking locks can be achieved, improving the operational efficiency and management level of parking lots. At the same time, this network deployment method also has good scalability and flexibility, and can adapt to parking lot scenarios of different scales and needs.

[0068] See also Figure 5 In this embodiment, the IoT wireless communication method based on the Star Flash protocol is an extremely simple deployment method.

[0069] 1. Set the module group numbers that need to be networked to be consistent.

[0070] 2. Set up a root node (gateway node).

[0071] 3. After completing the above two steps, the network can be automatically established, and then the transparent transmission address can be set as needed.

[0072] The above steps can all be performed on one node.

[0073] In summary, a wireless communication method for the Internet of Things based on the Star Flash protocol has the following effects:

[0074] Through the self-organizing network of wireless communication modules (wireless communication nodes), the networking of devices in a wide area is realized without the need to lay complex cables, thereby greatly reducing the cost of networking. Since there is no need for wiring, the difficulty and complexity of construction are significantly reduced, reducing construction time and labor costs. Wireless communication modules can be distributed arbitrarily, and communication can be achieved as long as the distance is less than 200 meters without obstacles. This flexibility allows the solution to adapt to various complex application scenarios. In summary, the IoT cascade wireless communication solution based on the Star Flash protocol has multiple effects such as reducing costs, improving flexibility and scalability, supporting mobile object communications, improving communication reliability and stability, and a wide range of applications. These effects make the solution have broad application prospects and market value in the field of IoT device communications. And it can be applied to centralized communications of mobile objects such as robots and drones. Comparison with various communication methods:

[0075] 1. Ethernet: Wireless protocol does not require wiring, construction, and supports mobile

[0076] 2. Wifi: There is no need to deploy routers at intervals. The wireless communication module of the present invention has built-in cascading and transfer functions. The device itself can be used as a transfer point, greatly reducing costs.

[0077] 3.4g: All modules can be connected to the gateway as a network outlet, without the need to insert a 4g card, greatly reducing long-term use costs.

[0078] 4. Bluetooth: The point-to-point transmission distance is longer than Bluetooth, up to 200 meters, and Bluetooth does not support data cascading and transfer functions.
