Problems solved by technology

[0005] (1) Passive detection: When the user finds an abnormal smell, etc., professionals will come to detect it. This kind of detection initiative is very poor, and it is easy to cause accidents
[0006] (2) Active detection: the method of line inspection is adopted, and the professional team detects once in a while, so the collected data is not timely and continuous, and hidden leakage points cannot be found in time
However, this invention does not connect and monitor user monitoring points, management centers, and users in real time, and does not develop the analysis and prevention functions of the monitoring center

Abstract

The invention discloses a natural gas monitoring management system. The system comprises a chip type integrated sensor, a sensor external control, a data collector, a wireless network transmission device, and a remote monitoring management platform and an App of a user intelligent terminal. According to the natural gas monitoring management system, the leakage condition of a natural gas pipeline is monitored remotely, and the data is transmitted to the remote monitoring management platform in time; and real-time prevention, accurate monitoring and timely feedback are achieved, so that the damage to the environment, and the life and property of people caused by natural gas leakage can be reduced.

Description

[0001] This application is a divisional application of a patent with an application number of 2015105680059 and an application date of September 8, 2015. technical field [0002] The invention relates to a natural gas monitoring system, in particular to an intelligent remote monitoring and management system for natural gas. Background technique [0003] Natural gas is a clean energy with abundant reserves, high thermal efficiency and low pollution. The main component of natural gas is methane, which is a flammable, explosive, and greenhouse gas whose greenhouse effect is dozens of times that of an equivalent volume of carbon dioxide. The way of natural gas transportation is now mostly underground pipelines. Therefore, natural gas leakage has a huge impact on the environment and the safety of people's lives and property. [0004] In the prior art, there are two ways to detect underground natural gas pipelines: [0005] (1) Passive detection: When the user finds abnormal sme...
