Oil field unattended anti-theft alarm device

Abstract

The invention provides an oil field unattended anti-theft alarm device comprising a laser generator, a plurality of laser transceivers and a laser receiver. The laser generator, the laser transceiversand the laser receiver are arranged around an oil well in sequence to form a laser fence. A laser signal emitted by the laser generator is transmitted to the laser receiver through the laser transceivers in turn. The laser receiver is connected with a GSM photo-taking anti-theft alarm. The laser fence and the GSM photo-taking anti-theft alarm are adopted to prevent crude oil from being stolen. Therefore, oil field unattended anti-theft alarm is realized.

Description

technical field [0001] The invention relates to an anti-theft alarm device, in particular to an unattended anti-theft alarm device for an oil field. Background technique [0002] my country is a country with a large amount of oil and also a country short of oil. The annual oil output is about 200 million tons. However, because most of these oil fields are distributed in the wild, thieves have an opportunity to take advantage of it, causing huge losses to the country. Although various protection measures have been taken in various types of oil fields, the effect is far from satisfactory. At present, the anti-theft methods adopted in the oil field are as follows: [0003] (1) Regular inspection of oil wells: The staff of the oil field inspect once every hour or half an hour to prevent thieves and deal with equipment failures. During the interval between inspections, they can drive to the oil well and steal a truckload of crude oil from the Christmas tree (a kind of oil produ...

Problems solved by technology

[0004] (2) Infrared radiation sensor: It is greatly affected by the external environment. Animals, birds, rainy and foggy weather, sand blowing, fallen leaves flying in the air, etc. will cause false alarms and the false alarm rate is high

The defense range is very narrow, the dead angle is large, and the effect is not ideal

[0005] (3) Ground induction coil: through buried cable detection and leaking cables, this kind of facility will cause false alarms for water and metal flowing in the defense area, and the cost is high, and the engineering volume is also large, which has high requirements for the overall environment.

[0007] It can be seen that there are still many defects and deficiencies in my country's oilfield anti-theft alarm system. Either the single detection method makes the detection accuracy not high, the false alarm rate is too high, and must cooperate with manual inspection; or the system is expensive and the project volume is large. Larger exposure to external influences and high maintenance costs
