Description

Technical Field

[0001] The present invention relates to a local area network control system, and more particularly to a local area network control system based on Bluetooth (registered trademark) and User Datagram Protocol. The present invention further relates to a local area network control system.

Background Art

[0002] In a local area network environment such as a home, office, or campus, users usually need to control multiple devices such as lighting fixtures, speakers, and televisions. However, since users usually need to use different applications or remote controls to control the above devices, they may need to switch between different interfaces. Such a control method is not only extremely inconvenient to use, but also very inefficient.

[0003] To solve this problem, solutions with centralized control functions have also emerged. With these solutions, convenience and efficiency have been greatly improved, and users can more easily control various devices within a local area network such as a home or office. However, in these solutions with centralized control functions, the use of cloud services is usually required, which significantly increases the cost of these solutions.

[0004] Both the specification of Chinese Patent Application Publication No. 116074398 and the specification of Chinese Patent Application Publication No. 116266905 disclose technical means related to control functions, but still cannot effectively solve the problems of the prior art.

[0020] Hereinafter, with reference to the accompanying drawings, embodiments of a local area network control system and method based on Bluetooth (registered trademark) and User Datagram Protocol of the present invention will be described. However, for the sake of easy understanding and easy explanation in the drawings, each member in the drawings may be shown with exaggerated or reduced dimensions and ratios. In the following description and / or claims, when a member is described as being "connected" or "coupled" to another member, it may be directly connected or coupled to the other member, or there may be an intervening member. When a member is described as being "directly connected" or "directly coupled" to another member, there is no intervening member, and the same should be interpreted for other terms used to explain the relationship between members or layers. For easy understanding, the same members in the following embodiments will be described with the same reference numerals.

[0021] FIG. 1 is an explanatory diagram of a local area network control system based on Bluetooth (registered trademark) 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 number of the above gateways and Bluetooth (registered trademark) devices is merely an example and can be adjusted according to actual needs, and the present invention is not limited thereto.

[0022] The first gateway 12A is a Bluetooth (registered trademark) mesh network gateway and manages a plurality of first Bluetooth devices 11A. In one embodiment, the plurality of first Bluetooth devices 11A 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 a SQLite database. In another embodiment, the first local database 13A may be a MySQL (registered trademark) database, a PostgreSQL database, or an H2 database.

[0024] The second gateway 12B manages a plurality of second Bluetooth devices 11B and is a Bluetooth (registered trademark) mesh network gateway for managing the plurality of second Bluetooth devices 11B. In one embodiment, the plurality of second Bluetooth devices 11B may be a television, a fan, a speaker, a computer, a lighting fixture, 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 a SQLite database. In another embodiment, the first local database 13A may be a MySQL (registered trademark) 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 explanation and does not limit the scope of the present invention. Equivalent modifications or changes made based on the Bluetooth (registered trademark) and user datagram protocol-based local area network control system of this embodiment should still be included in the protection scope of the present invention.

[0028] FIG. 2 is an explanatory diagram of a first operating state of a 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 the User Datagram Protocol (UDP). Since the first gateway 12A does not have information about other gateways within the local area network, the first gateway 12A described above needs to broadcast an information exchange request message M1 based on the User Datagram Protocol. The information exchange request message M1 includes the gateway information of the first gateway. The gateway information of the first gateway includes the Internet (IP) address of the first gateway 12A and the routing information (topology information) of the plurality of first Bluetooth devices 11A.

[0029] Of course, this embodiment is only used for illustrative explanation and does not limit the scope of the present invention. Equivalent modifications or changes made based on the local area network control system based on Bluetooth (registered trademark) and User Datagram Protocol of this embodiment should still be included in the protection scope of the present invention.

[0030] FIG. 3 is an explanatory diagram of a second operating state of a 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, the second gateway 12B receives the information exchange request message M1, analyzes the information exchange request message M1, and acquires the gateway information of the first gateway (including the Internet address of the first gateway 12A and the routing information of the plurality of first Bluetooth devices 11A). Thereafter, the second gateway 12B stores the routing information of the plurality of first Bluetooth devices 11A in the first local database 13A. In this way, the second gateway 12B can acquire the routing information of all Bluetooth (registered trademark) devices in the local area network (that is, the plurality of first Bluetooth devices 11A and the plurality of second Bluetooth devices 11B). Next, the second gateway 12B returns an information message M2 to the first gateway 12A based on the UDP unicast method 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 the routing information (topology information) of the plurality of second Bluetooth devices 11B.

[0031] Since the second gateway 12B has acquired 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, and can reduce the bandwidth occupied by this local area network.

[0032] Of course, this embodiment is only used for illustrative explanation and does not limit the scope of the present invention. Equivalent modifications or changes made based on the local area network control system based on Bluetooth (registered trademark) and User Datagram Protocol of this embodiment should still be included in the protection scope of the present invention.

[0033] FIG. 4 is an explanatory diagram of a third operating state of a 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, the first gateway 12A receives the information message M2, analyzes the information message M2, and acquires gateway information of the second gateway 12B (including the Internet address of the second gateway 12B and the route information of the plurality of second Bluetooth devices 11B). Then, the first gateway 12A stores the route information of the plurality of second Bluetooth devices 11B in the second local database 13B. In this way, the first gateway 12A can acquire the route information of all Bluetooth (registered trademark) devices in the local area network (that is, the plurality of first Bluetooth devices 11A and the plurality of second Bluetooth devices 11B). Next, the first gateway 12A returns a confirmation message M3 to the second gateway 12B based on UDP unicast according to the Internet address of the second gateway 12B.

[0034] Similarly, since the first gateway 12A has acquired 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, and reduce the bandwidth occupied by this local area network.

[0035] When the second gateway 12B has not received the confirmation message M3 from the first gateway 12A, the second gateway 12B periodically transmits the information message M2 to the first gateway 12A based on UDP unicast. Until the confirmation message M3 is received from the first gateway 12A, the second gateway 12B stops periodically transmitting the information message M2 to the first gateway 12A.

[0036] Through the above mechanism, all gateways within this local area network can obtain the routing information of all Bluetooth (registered trademark) devices within this local area network. Therefore, the control device 14 can control all Bluetooth (registered trademark) devices within this local area network via any gateway, and realize the centralized control function.

[0037] Of course, this embodiment is only used for illustrative explanation and does not limit the scope of the present invention. Equivalent modifications or changes made based on the Bluetooth (registered trademark) and local area network control system based on the User Datagram Protocol of this embodiment should still be included in the protection scope of the present invention.

[0038] FIG. 5 is an explanatory diagram of the fourth 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, the control device 14 transmits the control signal Cs to the first gateway 12A (or the second gateway 12B) to obtain the routing information of all Bluetooth (registered trademark) devices within this local area network (that is, the plurality of first Bluetooth devices 11A and the plurality of second Bluetooth devices 11B described above), and controls any Bluetooth (registered trademark) device within this local area network to realize the centralized control function.

[0039] If the WiFi signal is good, the control device 14 transmits the 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 transmits the control signal Cs to the first gateway 12A (or the second gateway 12B) based on the Bluetooth (registered trademark) communication protocol. In this way, the control device 14 can control all Bluetooth (registered trademark) devices within the local area network. Therefore, the local area network control system 1 can realize higher practicality and reliability.

[0040] When a third gateway (with a third local database connected to the third gateway) for managing a plurality of Bluetooth (registered trademark) devices is added to the local area network control system 1, this third gateway can execute the same operation mechanism as the above-described first gateway 12A. For example, the third gateway broadcasts an information exchange request message based on the User Datagram Protocol. The information exchange request message includes the gateway information of the third gateway. The gateway information of the third gateway includes the Internet address of the third gateway and the route information (topology information) of the plurality of Bluetooth (registered trademark) 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 Bluetooth (registered trademark) devices), and stores the route information of the plurality of Bluetooth (registered trademark) 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 Bluetooth (registered trademark) devices), and stores the route information of the plurality of Bluetooth (registered trademark) 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 the gateway information of the first gateway 12A (including the Internet address of the first gateway 12A and the routing information of the plurality of first Bluetooth devices 11A) and the gateway information of the second gateway 12B (including the Internet address of the second gateway 12B and the routing information of the plurality of second Bluetooth devices 11B).

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

[0045] From the above, through the above control mechanism, all gateways in the local area network can obtain the routing information of all Bluetooth (registered trademark) devices in the local area network. Therefore, it can be seen that the control device 14 can control all Bluetooth (registered trademark) devices in the local area network through any gateway. Therefore, the control device 14 can realize a centralized control function, which is more convenient in use and can achieve higher efficiency.

[0046] Also, in this embodiment, the local area network control system 1 can effectively integrate the Bluetooth (registered trademark) mesh network and the User Datagram Protocol, and can control all Bluetooth (registered trademark) devices in the local area network through any gateway without the need for the control device 14 to access the cloud service, and can realize a centralized control function. Therefore, the cost of the local area network control system 1 can be greatly reduced, the application of the local area network control system 1 can be further expanded, and the requirements of different applications can be met.

[0047] In addition, in this embodiment, the local area network control system 1 can effectively integrate the Bluetooth (registered trademark) mesh network and the User Datagram Protocol, making it more flexible in application and more convenient to manage. Therefore, the local area network control system 1 can more appropriately meet the requirements of actual applications.

[0048] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention. Equivalent modifications or changes made based on the local area network control system according to the Bluetooth (registered trademark) and User Datagram Protocol of this embodiment should still be included in the protection scope of the present invention.

[0049] In the solutions with the conventional centralized control function, usually, the use of cloud services is required, and the costs of these solutions increase significantly. In contrast, according to the first embodiment of the present invention, the 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 the 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 the 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 routing information of all Bluetooth (registered trademark) devices in the local area network, and the control device can control all Bluetooth (registered trademark) devices in the local area network via any gateway. Therefore, the control device can realize the centralized control function, which is more convenient in use and can achieve higher efficiency.

[0050] Also, according to the first embodiment of the present invention, the local area network control system can effectively integrate the Bluetooth (registered trademark) mesh network and the User Datagram Protocol, and can control all Bluetooth (registered trademark) devices in the local area network via any gateway without the need for the control device to go through the cloud service, thereby realizing the centralized control function. Therefore, the cost of the local area network control system can be significantly reduced, the application of the local area network control system can be further expanded, and the requirements of different applications can be satisfied.

[0051] Also, according to the first embodiment of the present invention, since the local area network control system can effectively integrate the Bluetooth (registered trademark) mesh network and the User Datagram Protocol, it has more flexibility in application and is more convenient to manage. Therefore, the local area network control system can more appropriately meet the needs of actual applications.

[0052] Also, according to the first embodiment of the present invention, the local area network control system effectively integrates the Bluetooth (registered trademark) mesh network and the User Datagram Protocol, and can provide a special control mechanism. Therefore, in a situation where the WiFi signal is good, the control device can obtain the routing information of all Bluetooth (registered trademark) devices in the local area network via any gateway based on the User Datagram Protocol, and in a situation where the WiFi signal is not good, the control device can obtain the routing information of all Bluetooth (registered trademark) devices in the local area network via any gateway based on the Bluetooth (registered trademark) communication protocol. In this way, the control device can control all Bluetooth (registered trademark) 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, since the local area network control system can effectively provide a centralized control function, it can meet the requirements of most users and can be applied to various different intelligent applications. Therefore, the local area network control system can conform to the trend of future development. From the above, it can be seen that the Bluetooth (registered trademark) and user datagram protocol-based local area network control system according to the embodiment of the present invention can surely achieve excellent technical results.
