LORA-based natural gas transmission remote monitoring system

Abstract

The invention relates to an LORA-based natural gas transmission remote monitoring system. The system comprises a plurality of natural gas intelligent detection systems and a natural gas background monitoring center wirelessly connected with the plurality of natural gas intelligent detection systems, wherein each natural gas intelligent detection system comprises a signal preprocessing circuit module, a natural gas branch pipe pressure sensor, a natural gas main pipe pressure sensor, a natural gas branch pipe flow sensor, a natural gas main pipe flow sensor, a natural gas branch pipe temperature detector, a natural gas main pipe temperature detector, a multipath analog switch, a DSP digital signal processing module, a data storage chip and an LORA communication transmitting module. Comparedwith the prior art, the system has the beneficial effects that abnormal data can be found in time, the property management personnel are informed to go to the site to eliminate hidden dangers, and the gas use safety of residential residents is guaranteed.

Description

【Technical field】

[0001] The invention relates to the technical field of natural gas transmission, in particular to a LORA-based remote monitoring system for natural gas transmission. 【Background technique】

[0002] Natural gas has been widely used in the community. The natural gas pipe organization in the community is diverted from a main pipe to several branch pipes to each household, which brings more and more convenience to people's life, but there are also many safety hazards.

[0003] Due to the relatively dense organization and complex intertwining of natural gas pipelines, it is very difficult to manage and detect. When an abnormality such as leakage occurs in one of the pipelines, property personnel generally cannot detect the specific location where the problem occurs in the first place, resulting in missing the best maintenance driver. Seriously It will lead to major safety accidents, and the life of residents in the community cannot be effectively guaranteed. ...
