Oilfield Security Intelligent Monitoring System Intrusion Detection Scheme

It is necessary to carry out perimeter prevention for the area of 1 square kilometer around the oil well. When a suspicious person or vehicle enters the prevention area, the monitoring system is required to automatically detect the intrusion target, identify its intrusion trajectory, and send an alarm to notify the management personnel to deal with it.
According to the above requirements, this plan will be constructed from the following aspects:
The equipment is set to intrusion detection mode, and fixed cameras are installed on the 1 square kilometer perimeter of the oil well area for seamless coverage, forming a virtual surveillance fence.
After calculation, when the camera uses a 40mm lens and the effective detection range of each camera (the effective detection range refers to the farthest distance that can completely display an object not higher than 3 meters in the monitoring cage-plane) is 100 meters, Belson The intelligent vision server can achieve the highest detection rate and the lowest false alarm rate (detection rate: 99.9%; false alarm rate: less than 1 per day).
Set all areas that are forbidden to invade within the perimeter monitoring range as defense zones. In this way, when an intruder intrudes into the guarded area, it will be automatically locked by the intelligent visual monitoring system and the action track will be marked, and an alarm will be issued at the same time. There are two types of alarms, front-end and back-end. The front-end alarm can be realized by sound and light alarm. When an intruder triggers an alarm, the monitoring system will sound an alarm to warn the intruder, and the strong light can be turned on so that the intruder has nowhere to hide. ; The back-end alarm can be realized through PC software, and the manager is notified to deal with the intrusion immediately. In this way, “precautions beforehand” is truly achieved and economic losses are avoided.
The recording function of the intelligent visual monitoring system can be set to “alarm-triggered recording”, that is, the recording function is triggered when an alarm occurs, which can filter out a large amount of useless recording content, which not only saves the space of the recording hard disk and prolongs the recording time, but also It avoids a lot of tedious work when watching the video, only need to confirm the video when the alarm occurs.
The intelligent visual monitoring system can detect intrusions from different directions. The direction of entering the defense zone can be set as the illegal direction, and the direction out of the defense zone is the legal direction. In this way, only people or vehicles entering the defense area are detected and alarmed, and those who leave the defense area are ignored.
The intelligent visual monitoring system supports schedule setting, which can carry out different detection methods for the divided time periods of the monitoring area. For example, the period from 9 a.m. to 5 p.m. is working hours, and there may be a large number of workers entering and leaving the defense zone. You can set this time as a non-detection period to avoid unnecessary alarms; and from 5 p.m. to the next time. The period of 5 o’clock in the morning of the day is the off-duty time, and no one is allowed to enter the defense zone, then it is set as the intrusion detection period and the prevention is started.
The intelligent vision server provides intelligent, flexible and effective intrusion detection functions. The intelligent vision server can automatically detect the intruders (people and vehicles) who intrude into the surveillance zone, can automatically distinguish the type, size, speed, moving direction and other characteristics of the intruder, and can effectively identify the camouflage.
The intelligent processing module has the ability of outdoor environment application, can carry out self-learning, self-adaptation and self-adjustment to the environment background, and there is no need to manually change the system parameters when the weather environment changes.
After the front-end equipment intelligently processes the input video stream, it supports dual-mode output of analog video and network streaming video at the same time, so it is easy to combine with traditional monitoring to achieve a comprehensive monitoring effect.
