Problems solved by technology

However, little research has been done on the monitoring and management of pipeline leaks from the gas transmission pipeline entering the building to the pipeline other than the users on each floor. Since this section of pipeline network is laid for residents to use gas, it is difficult to distinguish household gas from pipelines from a technical perspective. Due to air leakage, this section of pipeline is alternately connected with residential users, if a slight problem occurs, the consequences will be unimaginable

Embodiment 1

[0033] The infrasonic sensor 1 is installed at the bottom and top of the pipeline to detect the infrasonic signal in the pipeline; the infrared gas sensor is installed at the bottom of the pipeline to detect leaked natural gas; the solenoid valve is installed on the main pipeline leading to the building to detect When natural gas leaks, cut off the main pipeline directly; the communication module is a wired communication mode, connected to the host computer through a data line, transmits sensor data and leakage information, and accepts instructions from the host computer at the same time; the display module can display in real time whether there is a current leak point and the leak point Location.

[0034] When in use, firstly a time threshold is preset, and the infrasonic wave sensor 1 monitors the air leakage signal and the leakage location information. When the leak time of a certain point exceeds the preset time, it can be judged as a leak point. After natural gas leaks, ...

Embodiment 2

[0036] The solenoid valve is installed on the pipeline leading to the household, and after determining the location of the leakage point, cut off the user pipeline access at that location and related locations. All the other are the same as embodiment one.

Embodiment 3

[0038] The communication module is a wireless communication method, which transmits data to the host computer through ZigBee or WiFi, and receives instructions from the host computer. All the other are the same as embodiment one.

Abstract

The invention relates to a pipeline leakage detection and recognition technology in the field of public security, in particular to a monitoring, early warning and exhaust managing system for an operation pipeline in a building. The problem that at present, leakage detection for the pipeline section from output of an underground pipeline to a user is researched little is mainly solved. The monitoring, early warning and exhaust managing system for the operation pipeline in the building comprises monitoring equipment, a turn-off device, an exhaust device, a communication module, a display module and a data processing unit. Gas emission and emission time of the pipeline in the building are analyzed through infrasonic waves to determine a leakage point. A gas sensor is installed at the bottom end of a pipeline well to detect the gas concentration, after it is detected that the gas concentration exceeds a certain threshold value, the exhaust device is started to exhaust hazardous gas, and a solenoid valve is cut off simultaneously to prevent the hazardous gas from continuing aggregation. Pipeline leakage can be monitored in real time, the hazardous gas can be exhausted in time, security management can be carried out on all buildings of a pipeline gas supply type in an early warning mode, the requirement for city people safety is met, and the system is practical and feasible and has high popularization value.

Description

technical field [0001] The invention relates to pipeline leakage detection and identification technology in the field of public safety, and relates to a monitoring, early warning and exhaust management system for pipelines in buildings. Background technique [0002] In today's people's lives, coal-based gas and natural gas products have become indispensable and widely used products in the lives of urban and rural residents due to their advantages of convenience, economy, and sanitation, especially coal-based natural gas products supplied by pipelines. It directly supplies gas to residents' families, which brings great convenience to residents' life. However, everything has its two sides. The coal-to-gas natural gas products supplied by pipelines bring convenience and economic benefits to residents, but because of its uninterrupted supply function, once it is operated improperly, it will not only cause loss, but also It will threaten the safety of people's lives and affect s...
