When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.

[0047] Gas, as a widely used energy source, plays a vital role in our daily life. However, gas leaks occur from time to time, posing a serious threat to people's lives and property safety.

[0048] Gas detection is an important means of preventing gas leakage accidents. By timely and accurately detecting gas leaks, measures can be taken quickly to avoid accidents. At the same time, gas detection can also help users understand the gas usage status, discover potential safety hazards in time, and improve the safety of gas use. In addition, gas detection also helps to protect the environment and resources, reduce the pollution of the environment and the waste of resources caused by gas leaks. There are many technical methods for gas detection, the most common of which include combustible gas alarms, portable gas detectors, infrared spectrum detection technology, etc.

[0049] However, the gas detection device or alarm device only has a prompt function. When the user is not at home or it is inconvenient to handle, it cannot realize functions such as remote monitoring and timely processing, which has inconveniences and defects, endangers user safety, and causes property losses.

[0050] The smart home system is a multi-device network system based on the Internet of Things technology. It can realize the coordinated operation of multiple devices through network communication to meet the needs of users. For example, the smart home system can be composed of smart terminal devices such as smart TVs, smart refrigerators, smart terminals, and magic cube screens. Users can control the smart TV to play specific media by performing interactive actions on the smart terminal devices, and can also control the refrigeration temperature of the smart refrigerator by performing interactive actions on the magic cube screen, realizing the coordinated operation of multiple devices.

[0051] Based on this, the present application provides a refrigerator, a smart home system and a gas detection method. The refrigerator monitors the gas concentration in the air through the gas detection command sent by the user. When the gas concentration exceeds the preset threshold, an alarm message is promptly sent to at least one receiving device in the current smart home system that can respond to the current alarm message and whose status information is online. The present application implements the early warning notification to the user, closes the gas valve, and turns on the door and window exhaust fan through the smart home system, thereby realizing remote monitoring and timely processing functions to protect user safety.

[0052] In some embodiments, the present application provides a refrigerator, comprising:

[0055] Gas detector, used to detect the concentration of gas in the air; wherein the gas includes: natural gas, liquefied gas, coal gas; the gas detector can adopt mature gas detection modules on the market, or can be designed and developed by itself using oxide semiconductor type, catalytic combustion type, hot wire type gas sensor and other components. The detector needs to be installed in the refrigerator where it can be exposed to the outside air;

[0056] Controller for:

[0057] Obtain the gas detection instruction input by the user;

[0058] In response to the gas detection instruction, detecting the gas concentration in the air;

[0059] When the gas concentration exceeds a preset threshold, an alarm message is sent to a target device, where the target device is at least one receiving device in the current smart home system that can respond to the current alarm message and whose status information is online.

[0060] In some embodiments, the gas concentration in the air is calculated by detecting the gas leakage amount, the size of the kitchen space, the opening angle of the kitchen door and the opening angle of the kitchen window, so that different measures are taken according to different gas concentrations. It should be noted that whether a gas leak occurs can be determined by detecting whether there is an abnormal opening in the gas pipeline.

[0061] When the detected concentration exceeds the preset threshold, the controller controls the alarm module to alarm. The preset threshold meets the national standard 15322.2 "Combustible Gas Detectors Part 2: Household Combustible Gas Detectors", and can be set specifically according to experimental conditions (relevant national standards have requirements for setting alarm points for gas alarms: the combustible gas alarm concentration setting value range is a lower limit of 5%LEL to 25%LEL, and an upper limit of 50%LEL. "LEL" refers to the lower explosion limit, which is a technical term for combustible gases. The lowest concentration of combustible gas at which an open flame explodes in the air is called the lower explosion limit - "LEL" for short).

[0062] In some embodiments, when the refrigerator sends an alarm message to the target device, it starts a timer, and when the timed time exceeds a first time, it sends a first instruction to the smart home system to turn off the switch of the gas device;

[0063] When the timing time exceeds the second time, a second instruction is sent to the smart home system to start the ventilation device of the kitchen and open multiple windows in the smart home system.

[0074] If the number of the target devices is greater than 1, the target devices in active state are sorted according to the length of the running time, and an alarm message is sent to the target device with the longest running time.

[0075] In some embodiments, the refrigerator is further configured to:

[0076] If the number of the target devices is less than 1, the alarm information is sent to the cloud server through the network, so that the cloud server sends the alarm information to the terminal device bound to the cloud server after receiving the alarm information.

[0077] The smart home system described in the embodiment of the present application is a network system based on a specific area network and established based on a unified control service. The smart home system may include multiple terminal devices that establish communication connections with each other. Multiple terminal devices can achieve communication connections between devices by accessing the same local area network. Multiple terminal devices can also directly form a point-to-point network through a unified communication protocol to achieve communication connection. For example, multiple terminal devices can be connected to the same wireless local area network so that multiple terminal devices can communicate with each other. For example, a terminal device can also establish communication connections with multiple other terminal devices through Bluetooth, infrared, cellular network, power carrier communication, etc.

[0078] The terminal device refers to a device with communication function, which can receive, send, execute control instructions and realize specific functions. The terminal device includes but is not limited to smart display devices, smart terminals, smart home appliances, smart gateways, smart lighting devices, smart audio devices, game devices, etc. The multiple terminal devices that constitute the smart home system can be devices of the same type or different types. For example, in the same smart home system, it can include smart TVs, smart speakers, smart refrigerators, multiple smart lamps, etc. These terminal devices can be distributed in different locations to meet the usage requirements at the corresponding locations.

[0079] It should be noted that the smart home system described in this application does not limit the scope of application of the scheme to be protected by this application. That is, in practical applications, the terminal device, smart home system and information synchronization method provided by this application are not limited to the application in the field of smart home, but are also applicable to other systems that support intelligent voice control, such as smart office systems, smart service systems, smart management systems, industrial production systems, etc.

[0080] The terminal devices and servers that constitute the smart home system can communicate with each other to achieve comprehensive control of the smart home system. That is, the terminal device can report data to the server in the application, so that the server can analyze, judge, and process the data reported by the terminal device to generate control instructions for the terminal device. The server then sends the generated control instructions to the terminal device to achieve control of the terminal device's operating status.

[0081] Multiple terminal devices in the smart home system can also establish communication connections with each other to form an artificial intelligence & Internet of Things (AIoT) system. The AIoT system can integrate artificial intelligence and Internet of Things technologies, generate and collect data from different dimensions through the Internet of Things, and realize collaborative control of multiple terminal devices. By connecting multiple terminal devices to the same wireless LAN, communication connections can be established between multiple terminal devices. Any device can send shared data to the AIoT system, and any device can obtain data shared by other devices through the AIoT system to achieve collaborative operation in the smart home system.

[0082] In some embodiments, when presenting certain data (such as messages, pictures, videos, audio, etc.), the terminal device A in the smart home system can push the data to the terminal device B designated by the user, i.e., the receiving device, in response to user control, so that the receiving device continues to play the data or presents it on the receiving device.

[0083] In the above device interaction process, the terminal device A where the user performs the interaction can be used as the initiating device, and the terminal device B receiving the data can be used as the receiving device. Obviously, the initiating device and the receiving device are relative, that is, for the same terminal device, it can be used as the initiating device and the receiving device in different control processes.

[0084] For ease of explanation, in the following embodiments, the refrigerator is an initiating device; the terminal device that receives data and presents the data is called a receiving device.
