For ease of understanding, the same elements in the following embodiments will be denoted and described with the same reference numerals.

[0021] 1 is an explanatory diagram of a local area network control system based on Bluetooth and User Datagram Protocol according to a first embodiment of the present invention. As shown in the figure, the local area network control system 1 includes a plurality of first Bluetooth devices 11A, a first gateway 12A, a first local database 13A, a plurality of second Bluetooth devices 11B, a second gateway 12B, a second local database 13B, and a control device 14. The numbers of the gateways and Bluetooth devices mentioned above are merely examples and can be adjusted according to actual needs, and the present invention is not limited thereto.

[0022] The first gateway 12A is a Bluetooth mesh network gateway and manages a plurality of first Bluetooth devices 11A, which may be televisions, fans, speakers, computers, lighting fixtures, or various similar devices.

[0023] The first local database 13A is connected to the first gateway 12A. In one embodiment, the first local database 13A is an SQLite database. In another embodiment, the first local database 13A may be a MySQL database, a PostgreSQL database, or an H2 database.

[0024] The second gateway 12B is a Bluetooth mesh network gateway that manages a plurality of second Bluetooth devices 11B, which may be televisions, fans, speakers, computers, lighting fixtures, or various similar devices.

[0025] The second local database 13B is connected to the second gateway 12B. In one embodiment, the second local database 13B is an SQLite database. In another embodiment, the first local database 13A may be a MySQL database, a PostgreSQL database, or an H2 database.

[0026] The control device 14 can communicate with the first gateway 12A and the second gateway 12B. In one embodiment, the control device 14 is a smartphone. In another embodiment, the control device 14 is a tablet, a smartwatch, a laptop, or other similar device.

[0027] Of course, this embodiment is only used for illustrative purposes, not to limit the scope of the present invention, and any equivalent modifications or variations made based on the local area network control system based on Bluetooth (registered trademark) and user datagram protocol of this embodiment should still fall within the protection scope of the present invention.

[0028] 2 is an explanatory diagram of a first operating state of the local area network control system based on Bluetooth (registered trademark) and User Datagram Protocol according to the first embodiment of the present invention. As shown in the figure, first, the first gateway 12A broadcasts an information exchange request message based on User Datagram Protocol (UDP). Because the first gateway 12A does not have information about other gateways in the local area network, the first gateway 12A needs to broadcast an information exchange request message M1 based on User Datagram Protocol. The information exchange request message M1 includes gateway information of the first gateway. The gateway information of the first gateway includes the Internet Protocol (IP) address of the first gateway 12A and route information (topology information) of the multiple first Bluetooth devices 11A.

[0029] Of course, this embodiment is only used for illustrative purposes, not to limit the scope of the present invention, and any equivalent modifications or variations made based on the local area network control system based on Bluetooth (registered trademark) and user datagram protocol of this embodiment should still fall within the protection scope of the present invention.

[0030] FIG. 3 is an explanatory diagram of a second operating state of the local area network control system based on Bluetooth and User Datagram Protocol according to the first embodiment of the present invention. As shown in FIG. 3, the second gateway 12B receives the information exchange request message M1, analyzes the information exchange request message M1, and obtains the gateway information of the first gateway (including the Internet address of the first gateway 12A and the route information of the first Bluetooth devices 11A). The second gateway 12B then stores the route information of the first Bluetooth devices 11A in the first local database 13A. In this way, the second gateway 12B can obtain the route information of all Bluetooth devices (i.e., the first Bluetooth devices 11A and the second Bluetooth devices 11B) within the local area network. The second gateway 12B then returns an information message M2 to the first gateway 12A via UDP unicast according to the Internet address of the first gateway 12A. The information message M2 includes the gateway information of the second gateway 12B. The gateway information of the second gateway 12B includes the internet address of the second gateway 12B and route information (topology information) of the plurality of second Bluetooth devices 11B.

[0031] Since the second gateway 12B has obtained the Internet address of the first gateway 12A, the second gateway 12B can directly return the information message M2 to the first gateway 12A based on the UDP unicast method, thereby reducing the bandwidth occupied by this local area network.

[0032] Of course, this embodiment is only used for illustrative purposes, not to limit the scope of the present invention, and any equivalent modifications or variations made based on the local area network control system based on Bluetooth (registered trademark) and user datagram protocol of this embodiment should still fall within the protection scope of the present invention.

[0033] 4 is an explanatory diagram of a third operating state of the local area network control system based on Bluetooth and the User Datagram Protocol according to the first embodiment of the present invention. As shown in the figure, the first gateway 12A receives the information message M2, analyzes the information message M2, and obtains the gateway information of the second gateway 12B (including the Internet address of the second gateway 12B and the route information of the second Bluetooth devices 11B). The first gateway 12A then stores the route information of the second Bluetooth devices 11B in the second local database 13B. In this way, the first gateway 12A can obtain the route information of all Bluetooth devices (i.e., the first Bluetooth devices 11A and the second Bluetooth devices 11B) within the local area network. The first gateway 12A then returns a confirmation message M3 to the second gateway 12B via UDP unicast according to the Internet address of the second gateway 12B.

[0034] Similarly, since the first gateway 12A has obtained the Internet address of the second gateway 12B, the first gateway 12A can directly return the confirmation message M3 to the second gateway 12B based on the UDP unicast method, thereby reducing the bandwidth occupied by this local area network.

[0035] If the second gateway 12B has not received the confirmation message M3 from the first gateway 12A, the second gateway 12B periodically sends the information message M2 to the first gateway 12A based on UDP unicast. The second gateway 12B stops periodically sending the information message M2 to the first gateway 12A until it receives the confirmation message M3 from the first gateway 12A.

[0036] Through the above mechanism, all gateways in the local area network can obtain the route information of all Bluetooth devices in the local area network, so the control device 14 can control all Bluetooth devices in the local area network through any gateway, and realize the centralized control function.

[0037] Of course, this embodiment is only used for illustrative purposes, not to limit the scope of the present invention, and any equivalent modifications or variations made based on the local area network control system based on Bluetooth (registered trademark) and user datagram protocol of this embodiment should still fall within the protection scope of the present invention.

[0038] 5 is an explanatory diagram of the fourth operating state of the local area network control system based on Bluetooth and User Datagram Protocol according to the first embodiment of the present invention. As shown in the figure, the control device 14 sends a control signal Cs to the first gateway 12A (or the second gateway 12B) to obtain the route information of all Bluetooth devices in the local area network (i.e., the above-mentioned first Bluetooth devices 11A and the above-mentioned second Bluetooth devices 11B), and controls any Bluetooth devices in the local area network to realize the centralized control function.

[0039] If the WiFi signal is good, the control device 14 sends a control signal Cs to the first gateway 12A (or the second gateway 12B) based on the user datagram protocol. If the WiFi signal is not good, the control device 14 sends a control signal Cs to the first gateway 12A (or the second gateway 12B) based on the Bluetooth communication protocol. In this way, the control device 14 can control all Bluetooth devices in the local area network. Therefore, the local area network control system 1 can achieve higher practicality and reliability.

[0040] When a third gateway (a third local database is connected to the third gateway) for managing multiple third Bluetooth devices is added to the local area network control system 1, the third gateway can implement the same operation mechanism as the first gateway 12A described above. For example, the third gateway broadcasts an information exchange request message based on the User Datagram Protocol. The information exchange request message includes gateway information of the third gateway. The gateway information of the third gateway includes the Internet address of the third gateway and route information (topology information) of the multiple third Bluetooth devices described above.

[0041] Thereafter, the first gateway 12A receives and analyzes the information exchange request message, obtains the gateway information of the third gateway (including the Internet address of the third gateway and the route information of the plurality of third Bluetooth® devices), and stores the route information of the plurality of third Bluetooth® devices in the first local database 13A. Similarly, the second gateway 12B receives and analyzes the information exchange request message, obtains the gateway information of the third gateway (including the Internet address of the third gateway and the route information of the plurality of third Bluetooth® devices), and stores the route information of the plurality of third Bluetooth® devices in the second local database 13B.

[0042] Next, since the first gateway 12A and the second gateway 12B have already obtained the internet address of the third gateway, the first gateway 12A and the second gateway 12B return an information message to the third gateway based on the UDP unicast method.

[0043] The third gateway receives and analyzes the information message to obtain gateway information of the first gateway 12A (including the Internet address of the first gateway 12A and the route information of the above-mentioned multiple first Bluetooth devices 11A) and gateway information of the second gateway 12B (including the Internet address of the second gateway 12B and the route information of the above-mentioned multiple second Bluetooth devices 11B).

[0044] Finally, the third gateway stores the route information of the plurality of first Bluetooth devices 11B and the route information of the plurality of second Bluetooth devices 11B in a third local database, and returns a confirmation message to the first gateway 12A and the second gateway 12B.

[0045] From the above, it can be seen that through the above control mechanism, all gateways in the local area network can obtain the route information of all Bluetooth devices in the local area network, so that the control device 14 can control all Bluetooth devices in the local area network through any gateway. Therefore, the control device 14 can realize the centralized control function, which is more convenient to use and achieves higher efficiency.

[0046] Furthermore, in this embodiment, the local area network control system 1 can effectively integrate the Bluetooth mesh network and user datagram protocol, allowing the control device 14 to control all Bluetooth devices in the local area network through any gateway without the need for a cloud service, thereby realizing a centralized control function, thereby significantly reducing the cost of the local area network control system 1 and further expanding the applications of the local area network control system 1 to meet the requirements of different applications.

[0047] In addition, in this embodiment, the local area network control system 1 can effectively integrate the Bluetooth mesh network and the user datagram protocol, which makes the application more flexible and the management more convenient, so that the local area network control system 1 can better meet the needs of actual applications.

[0048] Of course, this embodiment is only used for illustrative purposes, not to limit the scope of the present invention, and any equivalent modifications or variations made based on the local area network control system based on Bluetooth (registered trademark) and user datagram protocol of this embodiment should still fall within the protection scope of the present invention.

[0049] However, conventional solutions with centralized control functions usually require the use of cloud services, which significantly increases the cost of these solutions. In contrast, according to a first embodiment of the present invention, a local area network control system includes a plurality of first Bluetooth devices, a first gateway, a plurality of second Bluetooth devices, a second gateway, and a control device. The first gateway manages the plurality of first Bluetooth devices. The second gateway manages the plurality of second Bluetooth devices. The first gateway broadcasts an information exchange request message based on the User Datagram Protocol. The second gateway receives and analyzes the information exchange request message to obtain gateway information of the first gateway, and returns an information message based on the User Datagram Protocol to the first gateway. The first gateway receives and analyzes the information message to obtain gateway information of the second gateway. The control device controls one or more of the plurality of first Bluetooth devices and the plurality of second Bluetooth devices via the first gateway or the second gateway. Through the above control mechanism, all gateways in the local area network can obtain the route information of all Bluetooth devices in the local area network, and allow the control device to control all Bluetooth devices in the local area network through any gateway. Therefore, the control device can realize the centralized control function, which is more convenient to use and achieves higher efficiency.

[0050] Furthermore, according to the first embodiment of the present invention, the local area network control system can effectively integrate the Bluetooth mesh network and the user datagram protocol, allowing the control device to control all Bluetooth devices in the local area network through any gateway without the need for a cloud service, thereby realizing a centralized control function, thereby significantly reducing the cost of the local area network control system, further expanding the application of the local area network control system, and meeting the requirements of different applications.

[0051] Furthermore, according to the first embodiment of the present invention, the local area network control system can effectively integrate the Bluetooth mesh network and the user datagram protocol, which makes the application more flexible and the management more convenient, and therefore the local area network control system can better meet the needs of actual applications.

[0052] Furthermore, according to the first embodiment of the present invention, the local area network control system can effectively integrate a Bluetooth mesh network and a user datagram protocol to provide a special control mechanism. Therefore, when the WiFi signal is strong, the control device can obtain route information of all Bluetooth devices in the local area network through any gateway based on the user datagram protocol. Also, when the WiFi signal is weak, the control device can obtain route information of all Bluetooth devices in the local area network through any gateway based on the Bluetooth communication protocol. In this way, the control device can control all Bluetooth devices in the local area network. Therefore, the local area network control system can achieve higher practicality and reliability.

[0053] Furthermore, according to the first embodiment of the present invention, the local area network control system can effectively provide centralized control functions, so that it can meet the requirements of most users and can be applied to a variety of different intelligent applications. Therefore, the local area network control system can adapt to future development trends. From the above, it can be seen that the local area network control system based on Bluetooth and user datagram protocol in the embodiment of the present invention can indeed achieve excellent technical results.
