Fire intelligent detection system and control method thereof

Abstract

The invention provides a fire intelligent detection system and a control method thereof. The system comprises multiple groups of flame detectors, an information processing unit, a PTZ camera and an upper computer monitoring center; each group of flame detectors is complied into a monitored region in a latticed manner, and used for collecting flame data information of different regions and transmitting the information to the information processing unit; a photoelectric self-identification device can be arranged at each flame detector; each photoelectric self-identification device is connected with the information processing unit and used for giving an alarm signal through the control of the information processing unit when the flame detector at a corresponding location collects abnormal data; the PTZ camera is connected with the information processing unit, the PTZ camera tracks the alarm signal sent out by the photoelectric self-identification device; and the image data at the photoelectric self-identification device region is collected and then sent to the information processing unit. The automatic precise sensing on the fire occurrence location can be realized, the fire alarm monitoring is more reliable, and the misinformation resistance is higher.

Description

technical field [0001] The invention relates to the design field of fire protection technology, in particular to an intelligent fire detection system and a controller method thereof. Background technique [0002] Common fire-fighting equipment currently on the market includes smoke sensors, ultraviolet and infrared sensors, other sensors, and a simple fire detection system based on video images. [0003] Among them, the smoke sensor realizes fire prevention by detecting the concentration of smoke, and is divided into ion smoke alarm and photoelectric smoke alarm. In the case of people smoking, the smoke detector is too sensitive to cause false alarms, and it is easy to cause false alarms to accumulate on the sensor and the circuit board in the case of large steam or humidity. [0004] The disadvantage of the ultraviolet flame sensor is that it has poor sensitivity, the detection distance is less than 15m, it cannot resist the interference of lightning, and there is a certai...

Problems solved by technology

In the case of people smoking, the smoke detector is too sensitive to cause false alarms and it is easy to cause false alarms to accumulate on the sensor and circuit board in the case of large steam or humidity

[0004] The disadvantage of the ultraviolet flame sensor is that the sensitivity is poor, the detection distance is less than 15m, it cannot resist the interference of lightning, and there is a certain false alarm rate, so it can only be used in a closed environment with a short distance

[0005] The disadvantage of infrared detectors sensitive to optical radiation is that this type of sensor is piezoelectric and is very sensitive to sound, electromagnetic waves and vibrations, and its use is limited to a certain extent. Its detection distance is less than
