Problems solved by technology
[0003] After analysis, it is found that the existing wireless fire detection system based on flame detectors has the following deficiencies; first: the emergency alarm method is single and has limitations; second: the response is not sensitive enough; third: wireless detection cannot be realized
[0004] After analysis, it is found that the existing alarm system used with flame detectors has the following deficiencies; first: the alarm has hysteresis; second: it is vulnerable to external interference and has low reliability; third: the alarm method is relatively single
[0005] After analysis, it is found that the existing fire-fighting system used with flame detectors has the following deficiencies: first: unable to make timely and effective countermeasures; second: unable to deal with a large amount of dense smoke on site; third: unclear guidance for crowd evacuation

Provided is an integrated fire detection, alarm and fire fighting comprehensive management system for buildings. A wireless fire detection system has the advantages of various warning modes, sensitivedetection reaction, wireless detection, and the like. An alarm system has the advantages of timely alarm, completion of alarm the first time, high reliability and various alarm modes, and the like. Afire fighting system has the advantages as follows: timely and effective measures can be taken; a lot of smoke in the field can be handled; crowd evacuation guide is clear; and the like. A multi-frequency infrared sensor has the advantages as follows: the detection precision is high; the influence of ambient light interference is small; the sensor is safe and reliable in use; the sensor can meetthe different needs of more occasions; and the like. An infrared-ultraviolet composite flame detector has the advantages as follows: an infrared ultraviolet lens can be protected; infrared and ultraviolet light can be gathered; wide-angle detection can be carried out; and a transistor and a single-chip microcomputer inside can be well protected. A video flame detector has the advantages as follows: flame and light can be distinguished; video data conversion is stable; and video data transmission is fast.
Description
technical field [0001] The invention relates to the construction field, in particular to an integrated fire detection, alarm and fire protection comprehensive management system for buildings. Background technique [0002] Flame detectors are used to detect invisible light radiation that is visible or absent in the atmosphere while producing smoke and releasing heat when a substance is burning. According to the optical characteristics of the flame, there are three types of flame detectors used: one is an ultraviolet detector that is sensitive to ultraviolet radiation with a shorter wavelength in the flame; the other is an infrared detector that is sensitive to infrared radiation with a longer wavelength in the flame. detector; the third is a UV / IR hybrid detector that simultaneously detects both short-wavelength ultraviolet rays and long-wavelength infrared rays in flames. [0003] After analysis, it is found that the existing wireless fire detection system based on flame de...
