[0027] The following will describe the embodiments of the present utility model in conjunction with Figures 1 to 3 , to describe the embodiments of the present utility model.

[0028] As Figures 1-3 shown, according to an embodiment of the present utility model, on the one hand, a gas detection system is provided, which includes a detection device. The detection device includes a gas detector 2, a controller 1, and an alarm. The gas detector 2 is used to detect the gas concentration in a space; the gas detector 2 is electrically connected to the controller 1; the alarm is electrically connected to the controller 1; the controller 1 can control the opening and closing of the alarm according to the gas concentration detected by the gas detector 2; when the gas detector 2 detects that the gas concentration in the space exceeds a preset value, the controller 1 controls the alarm to turn on. The gas detection system of this application can timely understand the gas leakage situation, facilitate timely response and handling of such gas leakage, and thus prevent problems such as explosion, burns, or poisoning caused by such gas leakage. The alarm can be a light or sound alarm; it can also be a platform alarm. For example, the controller 1 transmits the alarm information to terminals such as the user's mobile phone and computer, or transmits it to some websites. This application solves the problems of traditional detection devices that only support local alarm; and the problem that personnel cannot timely perceive and handle local alarm.

[0029] Some embodiments are also disclosed in this application, where the gas includes combustible gas. The gas can also be a toxic gas; the gas can be any one or a mixture of several gases such as methane, propane, carbon monoxide, etc.

[0030] The present application also discloses some embodiments. The gas detector 2 includes at least one of a methane sensor, a propane sensor, and a carbon monoxide sensor. By detecting the concentration of methane in the air through the methane sensor to determine whether methane leaks, the leakage situation of methane gas can be understood in a timely manner, facilitating timely response and treatment to the leakage of methane, thereby preventing problems such as explosion and burns caused by methane leakage. By detecting the concentration of propane in the air through the propane sensor to determine whether propane leaks, the leakage situation of propane gas can be understood in a timely manner, facilitating timely response and treatment to the leakage of propane, thereby preventing problems such as explosion and burns caused by propane leakage.

Unattended supervision and timely response are achieved at the leakage site. The present application greatly reduces the manual monitoring cost and improves the response speed of leakage monitoring.

After data processing by the MCU main control unit, the monitoring device makes a judgment on the over-limit alarm of the flammable gas concentration. If the concentration exceeds the alarm set value, the monitoring device issues an alarm. The monitoring device sends data (such as normal, faulty, alarm data, etc.) to the LORA gateway module. Multiple monitoring devices are matched with one LORA gateway to form a networking method, which packages all the monitoring device data and then transmits the data to the cloud through the wireless module. The device status can be viewed through the mobile APP and the web end of the cloud platform, and a mobile phone text message alarm prompt or a telephone voice prompt can be received.

[0039] This application consists of a LORA wireless module, a methane sensor, an MCU main control unit, an ACDC module, and a structural member. This application uses LORA wireless networking technology to achieve real-time transmission of small amounts of data in the event of propane leakage. When a flammable gas leak occurs, the propane sensor installed at the site of the protected area converts the concentration parameter of the leaked flammable gas into an electrical signal.

If the concentration exceeds the alarm set value, the monitoring device issues an alarm. The monitoring device sends data (such as normal, faulty, alarm data, etc.) to the LORA gateway module. Multiple monitoring devices are matched with one LORA gateway to form a networking method, which packages all the monitoring device data and then transmits the data to the cloud through the wireless module. The device status can be viewed through the mobile APP and the web end of the cloud platform, and a mobile phone text message alarm prompt or a telephone voice prompt can be received.

[0040] Using LORA wireless networking technology, real-time transmission of small amounts of data in the event of carbon monoxide leakage is achieved. When a flammable gas leak occurs, the carbon monoxide sensor installed at the site of the protected area converts the concentration parameter of the leaked flammable gas into an electrical signal. After data processing by the MCU main control unit, the monitoring device makes a judgment on the over-limit alarm of the flammable gas concentration. If the concentration exceeds the alarm set value, the monitoring device issues an alarm. The monitoring device sends data (such as normal, faulty, alarm data, etc.) to the LORA gateway module. Multiple monitoring devices are matched with one LORA gateway to form a networking method, which packages all the monitoring device data and then transmits the data to the cloud through the wireless module.
