热成像监控技术在海外油气管道工程中的应用

The Application of Thermal Imaging Cameras in Overseas Oil and Gas Pipeline Projects

摘要: 在海外高风险地区，油气站场安防要求工业电视监控系统能实现“预警”，监控距离要求至少1 km，油气管道工程传统的监控技术无法达到这一要求。针对此，本文提出了热成像监控技术，它利用热释电效应，根据不同温度的物体发出不同的红外线来识别监控对象，同时利用智能识别技术对监测对象进行安全识别。热成像监控技术只取决于监控对象的温度差异，不受环境因素影响，监控距离达1~10 km，同时后端智能识别技术，能根据入侵者的体貌特征进行分析来实现“预警”，为站场运维人员争取更多时间来处理报警事件。

Abstract: In overseas high-risk areas, gas stations field of security requirements for industrial TV monitoring system can achieve an “early warning” requirement for monitoring distance of at least 1 km, oil and gas pipeline project traditional monitoring technology cannot meet this requirement. For this, we propose a thermal imaging surveillance technology, which uses pyroelectric effect, issued by different infrared objects, depending on the temperature monitor to identify objects, while taking advantage of intelligent object recognition technology to monitor secure identification. Thermal imaging surveillance technology depends only on the temperature difference between the monitored objects, from environmental factors, monitoring distance of 1~10 km, while the back-end intelligent recognition technology can be analyzed according to the physical characteristics of the intruder to achieve an “early warning” for the station field operation and maintenance personnel for more time to deal with the alarm event.
