Description
Technical field
The utility model relates to the intelligent security guard technical field, especially relates to a kind of fire early-warning system of field joint stations based on video image.
Background technology
Field joint stations be by oil field produced crude oil and rock gas collect, the important place of storage, preparatory processing and processing, storage and outer oil transportation product, be oil recovery factory's crude oil and rock gas outer defeated " throat " and " heart ".As collecting and distributing ，Zhan district, the place oil gas of oil gas transfer, concentrate, in length and breadth, and these equipment are many at certain pressure and temperature, operates for equipment, and the material of processing has inflammable, explosion hazard, so Fire risk analysis is very big.
Fire is one of disaster of harm humans, be a kind of on space-time out of control combustion phenomena.Life and property that it directly jeopardizes the mankind, cause environmental pollution, even the ecologic equilibrium.Therefore, it being carried out in real time to effectively monitoring and warning, is fire control one of the hot research content in fire Prevention Technique field in minimum zone.
Domestic fire alarm technology mainly relies on the sensor device detection of fires scenes such as smoke detector, heat detector, sensitive detector at present, has following defect and deficiency:
(1) smoke-sensitive fire detector is the flue gas of detection of fires generation and sends alerting signal.After fire occurred, the fire smoke that temperature is higher moved upward, and was installed on the concentration that smoke detector on ceiling detects flue gas and was greater than a certain limiting concentration, will send alerting signal.But in large space, when fire smoke rises to tens meters or tens meters eminences, be subject to the dilution of air, its temperature and concentration all reduce greatly, and the flue gas concentration that arrives ceiling does not reach alarm limit, sense cigarette probe just can not produce alerting signal.And the dust concentration in environment is excessive, can cause that false alarms of smoke fire detectors is alert, and long-term dust atmosphere and excessive humidity also can make to feel cigarette type detector and lost efficacy, produce false alarm or do not report to the police.
(2) the temperature sensitive type fire detector is to survey the temperature variation produced due to fire to send alerting signal.In large space, when too high or gas velocity air of spatial altitude is greater than 5m/s, all can affect the induction of heat detector, be difficult to realize that incipient fire reports to the police.
(3) optical flame fire detector is survey the infrared or ultraviolet light that flame sends and send alerting signal.This detector is because criterion is single, easily high power thermal source or high light (as electric arc etc.) produced to false alarm.
(4) compound fire detector is not eliminated above shortcoming fully, only increase the number of criterion, the overall performance of popping one's head in is improved, but in the situation that environmental aspect relatively severe, have numerous interference (dust, electromagnetic interference (EMI), water vapor, air-conditioning, light interference, vibrations etc.), still can't be applied to the detection alarm of large space fire.
(5) traditional detector mostly is applied in less space, installing space as heat detector is no more than 10 meters, the installing space of smoke detector is no more than 15 meters, in 0.5 meter, shelter cannot be arranged around detector, is not suitable for using in large space.
In sum, uncertainty and polytrope due to the fire generation, common temperature-sensitive, sense cigarette, sensitization and compound fire detector inevitably to be subject to the area of monitoring environment, highly, the impact of the factors such as humidity, dust, air-flow, these impacts are more obvious in the detection of large space, fire detector of the prior art also exists that investigative range is little, antijamming capability is weak, rate of false alarm is high, be difficult to meet early detection and forecast defect and the deficiency that the fire under the multi-purpose station complex environment requires, and can't realize real-time and accurately early warning.
