Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0037] Accordingly, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0038] Embodiment 1

[0039] Please refer to Figure 1 , the present invention provides a technical solution: a smart home system based on Bluetooth communication technology that can be controlled offline, including:

[0040] A user terminal, which is internally provided with a first Bluetooth module;

[0041] An execution device, which includes smart home devices and environmental perception devices, and the environmental perception devices are used to collect real-time environmental data of the home environment;

[0042] A main controller, which is used to obtain the real-time environmental data collected by the environmental perception devices and the real-time status data of the smart home devices, and the main controller sends control instructions to the smart home devices;

[0043] An Internet of Things cloud platform, which is used to realize two-way communication between the user terminal and the main controller;

[0044] Among them, the main controller includes a WiFi module and a second Bluetooth module. The WiFi module is used for wireless communication between the main controller and the Internet of Things cloud platform, and the second Bluetooth module is used for wireless communication between the main controller and the user terminal.

[0045] The Internet of Things cloud platform can specifically adopt the OneNET cloud platform, combined with the MQTT protocol, so that parts such as the STM32F103C8T6 main controller, smart home devices, and environmental perception devices form a smart home system that can be controlled offline. The user terminal can specifically use devices such as mobile phones and tablets with Bluetooth functions.

[0046] The environmental perception devices include temperature and humidity sensors, water immersion sensors, gas alarms, door and window sensors, and illuminance sensors. The smart home devices include smart lights, air conditioners, electric curtains, and door and window motors.

[0047] When the smart home system that can be controlled offline is in use, under normal conditions, the user can realize two-way communication between the user terminal and the main controller through the Internet of Things cloud platform. The user can view the home environment in real time through the user terminal and remotely control home devices using the main controller. When there is no network in the home environment, the main controller can use the second Bluetooth module to realize communication with the user terminal and achieve offline control of the smart home system.

[0048] The main controller includes a communication management module, which includes a network detection unit, a communication switching unit, and a network disconnection warning unit. The network detection unit is used to detect the network status of the home environment. The communication switching unit is used to switch the wireless communication mode of the main controller between the WiFi module and the second Bluetooth module. The network disconnection warning unit is used to send a network disconnection warning message to the user terminal through the Bluetooth communication mode in case of network disconnection.

[0049] When the network status of the home environment is poor, resulting in the main controller being unable to communicate with the Internet of Things cloud platform, the main controller detects the network disconnection in a timely manner through the communication management module. When the main controller and the user terminal are in a Bluetooth connection state, the main controller realizes offline communication with the user terminal through the second Bluetooth module and sends a network disconnection warning message to the user terminal, prompting the user of the user terminal to actively check and maintain the network.

[0050] Working principle: Through environmental perception devices, real-time environmental data in the home environment, including temperature, humidity, brightness, etc., can be monitored in real time. And through water immersion sensors and gas alarms, it can be detected whether there is water leakage or gas leakage in the home environment, and through door and window sensors, the opening and closing conditions of doors and windows in each room of the home environment can be detected. Thus, the smart home system can execute control instructions according to the real-time situation of the home environment and avoid executing control instructions with risks.

[0051] For example, when there is a gas leak inside the house, the main controller controls the window motor to start and open the window, rather than executing the control instruction to close the window and start the air conditioner.

[0052] Conversely, when the user starts the air conditioner, the opened window can be automatically closed, and the curtain can be automatically unfolded when the indoor-outdoor temperature difference is large to improve the temperature adjustment efficiency of the air conditioner.

[0053] Embodiment 2

[0054] Based on the above embodiment, this embodiment further makes the following improved technical solutions: The main controller is connected to a display 1, and the display 1 is used for visual display of the real-time environmental data of the home environment and the real-time status data of smart home devices.

[0055] To achieve the visual management of the smart home system, so that the user can, without the user terminal, use the display 1 to visually display the real-time environmental data of the home environment and the real-time status data of smart home devices, and can input control instructions to the main controller through the touch-control display 1 to achieve the management of the smart home system and further achieve the offline control of the smart home system.

[0056] Embodiment 3

[0057] On the basis of the above embodiment, the following improved technical solutions are further provided in this embodiment: A physical switch 2 is provided on the display 1, and the physical switch 2 is connected to the main controller.

[0058] To improve the security of the smart home system, the user can input a communication switching signal to the main controller through the physical switch 2. The main controller switches from WiFi communication to Bluetooth communication, so that the main controller actively disconnects the communication with the Internet of Things cloud platform, reducing the risk of communication intrusion and improving the security of the smart home system.

[0059] Embodiment 4

[0060] On the basis of the above embodiment, the following improved technical solutions are further provided in this embodiment: A biometric recognition module is also provided on the display 1. The biometric recognition module includes a face recognition camera 3 and a fingerprint recognition sensor. The face recognition camera 3 and the fingerprint recognition sensor of the biometric recognition module are used to collect face information and fingerprint information.

[0061] The communication switching signal input through the physical switch 2 is executed by the main controller after verifying the face information and fingerprint information, avoiding misoperation of the physical switch 2.

[0062] Specifically, the fingerprint recognition sensor can be set as a press-type fingerprint recognition sensor, and the fingerprint recognition sensor is provided on the physical switch 2. Integrating the fingerprint recognition function on the physical switch 2 simplifies the structure of the display 1 on the one hand, and ensures that the communication switching signal input by the physical switch 2 will only be executed by the main controller after the fingerprint recognition is passed on the other hand.

[0063] Further, a mode indicator light 4 is also provided on the display 1. The mode indicator light 4 is connected to the main controller, and indicates whether the main controller is currently in the WiFi communication state or the Bluetooth communication state through lights of different colors.

[0064] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
