Antitheft alarm system and method for oil or gas delivering pipeline

Abstract

An antitheft alarm system for the oil or gas delivery pipeline is composed of a central station and several terminal stations. Said central station consists of display screen, computer, sound-light alarm, interface, radio data transmission module, printer, UPS, and stabilized DC power supply. Said terminal station is composed of audio sensor, amplifier, signal processor, A / D converter, single-chip computer, interface, radio data transmission module, solar battery, etc. It can sense the theft in time to generate audio-video alarm signals, preventing pipeline from being damaged.

Description

technical field

[0001] The invention relates to an anti-theft alarm system for oil and gas pipelines, more precisely, it relates to a safety protection measure that can enable oil and gas fields and refineries to produce normally, transport oil and gas normally, and nearby residents live in peace. Background technique

[0002] Oil and gas pipelines are the lifeblood of national economic construction. However, in recent years, some oil and gas pipelines have been scarred and shockingly damaged by some criminals, causing serious harm to the safety of pipeline transportation and causing huge losses to national property and people's lives. People's Daily reported on June 19, 2001 in the article "Oil and Gas Pipelines Are "Moaning"" that a certain pipeline storage and transportation company "has a total length of 2,600 kilometers. More than 1,100 cases of drilling and stealing oil have been found, showing an increasing trend year by year....The XX section of...

[0056] The anti-theft alarm system for oil and gas pipelines of the present invention is composed of a central master station and several terminal sub-stations. in:

[0057] see figure 1 : The central master station includes: a master station management machine 1, which is used to control the work of the entire system; a data transceiver system 2, which is connected to the master station management machine, and is used to communicate with terminal substations. Each terminal substation includes: pickup system 3, which is used to pick up the sound from theft and convert it into an electrical signal; amplifier system 4, whose input is connected to the output of pickup system 3, and used to convert the audio signal output by the acoustic sensor After filtering and amplifying, it is output to the A / D converter; the A / D converter 5, whose input is connected to the output of the amplifier system 4, is used for analog-to-digital conversion; the intelligent management system 6, whose ...
