They are only examples of systems and methods consistent with some aspects of the present application as described in detail in the claims.

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

[0048] Gas detection is an important means to prevent gas leakage accidents. By detecting gas leakage in a timely and accurate manner, measures can be taken quickly to avoid accidents. At the same time, gas detection can help users understand gas usage and discover potential safety hazards in a timely manner, improving the safety of using gas. In addition, gas detection helps protect the environment and resources, reducing the pollution of the environment and the waste of resources caused by gas leakage. There are various technical methods for gas detection, including combustible gas alarms, portable gas detectors, infrared spectroscopy detection technology, etc.

[0049] However, the detection device or alarm device for gas only has a prompt function, and when the user is not at home or it is inconvenient to handle, remote monitoring and timely handling cannot be achieved, which is inconvenient and defective, endangers user safety, and causes property loss.

[0050] The smart home system is a multi-device network system based on Internet of Things technology, which can realize the collaborative operation of multiple devices through network communication to meet the user's use demand. For example, the smart home system can be composed of smart TV, smart refrigerator, smart terminal, magic cube screen and other intelligent terminal devices.
