Large oil depots are usually distributed in swamps, deserts, basins and shallow seas far away from cities and sparsely populated areas. Due to the characteristics of their working environment and nature, there are the following problems in the control management and safety protection in this field:
1、 Oil depots are usually located in the outer suburbs, sparsely populated and wide areas. There are relatively few on-site watch and maintenance personnel. The traditional working method is that the staff patrol and inspect according to the shift arrangement, and each team usually has one to three people. Due to the long distance between the places to be inspected and the special environment of the oil depot, vehicles are not allowed to enter casually, so the staff need to walk in the divided area, and it takes ten or twenty minutes to walk between each station, and the staff workload is very large.
2、 The working environment of oil depot is highly dangerous. General oil depots are divided into two categories. One is the self provided oil depots required for oil field production. As a large enterprise, each oil field consumes a large amount of oil every day and must have sufficient reserves; The other is the refined oil depot of the refining and chemical enterprises subordinate to the oilfield, which is used to store the refined oil products produced by refining and hydrolysis. Oil, natural gas and other resources involved in the oil depot, the consequences of explosion and combustion after being ignited are immeasurable.
Therefore, we should pay attention to three aspects of safety in production engineering:
First, the production and operation status of the working equipment itself, such as whether the oil tanks and valves in the reservoir area leak, and whether the transmission pipelines of natural gas, kerosene and petrochemical are burst or damaged;
Second, supervise the compliance operation in the process of oil transportation, such as supervising the incoming and outgoing vehicles, recording the license plate number of incoming and outgoing vehicles, and supervising whether the staff violate the rules, such as smoking and using lighters;
Third, the perimeter guard alarm system to prevent the intrusion of irrelevant personnel for theft and destruction.
1. In the monitoring areas such as highway oil receiving and dispatching area, railway oil receiving and dispatching area and waterway oil receiving and dispatching area, if they must be installed in Zone 0, zone 1 and zone 2 due to the actual situation, the front-end camera shall be explosion-proof equipment.
2) In the area of the oil pump room, explosion-proof bullet camera or explosion-proof dome camera shall be configured according to the scale of the oil pump room, which can fully monitor the whole oil pump room and clearly see the specific operation process of the staff.
3) The oil storage area is equipped with explosion-proof bullet camera, explosion-proof PTZ camera and explosion-proof dome camera according to the number and capacity of oil tanks, which can fully monitor the operation of staff in the oil storage area
Camera selection requirements
——Explosion proof type
In areas 0, 1 and 2 of the product oil depot, it has the characteristics of flammability and explosion, including that under normal temperature, the gas in the air of the site reaches a certain concentration and will cause explosion in case of open fire. Therefore, the explosion-proof requirements of the front-end system and transmission process in this field. The state stipulates that there shall be no open fire within 100m of natural gas, oil, diesel, gunpowder and explosives. Explosion proof cameras shall be strictly equipped according to different explosion-proof levels of cameras.
——Waterproof and dustproof, day and night monitoring
Industrial monitoring requires high performance of the camera. It implements 24-hour monitoring and is used outdoors. Therefore, it is suitable to use explosion-proof gun with high definition and low illumination.
—— Large monitoring range
Cameras installed at entrances and exits, perimeter and open areas shall have wide vision, barrier free and wide monitoring range.
——Lightning protection type
The lightning protection and grounding of front-end equipment directly affect the safety and reliability of the whole project. The lightning protection principle is that all equipment should be installed within the protection range of lightning rod. The weakest link of the field monitoring system for lightning stroke is the power supply. It is very important to do a good job in power supply lightning protection. The key to power supply lightning protection is to do a good job in grounding. Therefore, it is necessary to adjust measures to local conditions according to specific terrain.
For the selection of the front-end camera of the video surveillance system, high-speed fastball, PTZ integrated camera, gun camera or a combination of the three are popular at present. The camera at the monitoring point is only selected by this girl according to the actual situation around the monitoring point and the focus of monitoring. The station valve chamber is in a dark environment, so it is necessary to use its own infrared camera.
——Infrared thermal imaging
In order to solve the defect that it is impossible to monitor in real time in foggy weather or over a long distance at night, an explosion-proof infrared thermal imaging camera can be selected, which can capture the temperature difference of the surrounding environment, convert it into video images after back-end processing, and support intrusion detection and abnormal temperature detection. It can play an early warning linkage function through video image analysis.
The camera can realize intrusion alarm. When someone or vehicle enters the warning area, the monitoring screen will prompt the alarm information to remind the monitoring personnel to pay attention to the intrusion of suspicious targets. In the important dangerous areas of the finished oil depot, such as oil storage area, loading and unloading area, the camera is equipped with intrusion alarm to realize safety warning and advance warning.
