Emergency evacuation indicating lamp with natural gas detection and alarm functions

Abstract

The invention discloses an emergency evacuation indicating lamp with natural gas detection and alarm functions, which comprises a fuel gas concentration detecting device, a first controller, an alarmdevice, a wireless communication module, a second controller and an executing device; the fuel gas concentration detecting device is connected with the first controller, and the first controller is connected with the alarm device and the wireless communication module; the second controller is connected with the first controller through the wireless communication module, and connected with the executing device. Through the fuel gas concentration detecting device mounted on the emergency evacuation indicating lamp, the fuel gas concentration is detected, and the detected fuel gas concentration is sent to the first controller; once the fuel gas is leaked, the first controller sends the control command to the second controller, and the second controller controls the executing device and further closes the general valve of the fuel gas pipeline, thus the fuel gas leakage is effectively stopped; the emergency evacuation indicating lamp is featured by simple operation, strong practicability and intelligence; the risk caused by fuel gas leakage is reduced.

Description

technical field [0001] The invention belongs to the technical field of gas detection and relates to an emergency evacuation indicator lamp with natural gas detection and alarm functions. Background technique [0002] Natural gas is not unfamiliar in our daily life. The laying of natural gas pipelines and the reservation of holes must be considered in the construction of modern urban buildings. Natural gas has entered our lives and brought great benefits to people's lives. Great convenience. Compared with traditional coal gas, natural gas has higher safety and cleanliness. Natural gas is non-toxic, easy to emit, lighter in specific gravity than air, and should not accumulate into explosive gas, which has great advantages in safety. However, as a combustible gas, natural gas still has the danger of explosion when it leaks, so it is very necessary to prevent and detect natural gas pipeline leakage. [0003] Due to the wide distribution of emergency evacuation indicator lights...

AI Technical Summary

Problems solved by technology

[0003] Due to the wide distribution of emergency evacuation indicator lights, they are used for emergency evacuation lighting. At present, the emergency evacuation indicator lights have a single function and cannot detect whether the gas is leaking. However, the existing gas leakage detection usually uses a gas alarm. The range is relatively limited, and the detection range is narrow. Once a gas leak occurs outside the detection area, it will not be possible to quickly detect the leaked gas concentration, and the valve of the gas pipeline cannot be quickly closed, which has the advantages of small detection range, low safety and The problem of poor intelligence characteristics seriously endangers the safety of personnel and equipment
