Description
Technical field
The present invention relates to sensor technical field, particularly relate to a kind of novel plastic optical fiber smoke sensor.
Background technology
The electronic cigarette sensor that security protection industry now adopts always, usually can produce the situation reported by mistake or lost efficacy in daily.This is because existing electronic cigarette sensor is active sensor, all smoke detectors are all connected in parallel, and when circuit breaks down, often cause all cisco unity malfunctions because smoke detector is abnormal.Electronic cigarette sensor is due to the reason of structural design; more when monitoring that place dust a bit large or time has grown the accumulation of dust; usually can cause the wrong report of smoke detector, because the industry specifies that each smoke detector must clean once in two years, to ensure the performance of smoke detector.
Ionic formula smoke detector, the series connection room including Am241 radioactive source by two, field effect transistor and on-off circuit form.Sensitivity is relatively good, and compares the place being applicable to easily produce dense black smoke; But there is small radiation, leading position replace by photo-electric.
Photo-electric type smoke detector, is made up of light source, photovalve and electronic switch.Utilize light scattering principle to detect the smog that Initial Stage of Fire produces, and send alerting signal in time.Different according to light source, general photo-electric, laser light electric-type, ultraviolet light photo-electric and infrared light photo-electric etc. 4 kinds can be divided into.
According to purpose classification: self smoke detector, be generally 9V powered battery, on-the-spot sound and light alarm; Be applicable at home, shop, rental house, hotel's dormitory, the places such as community use.The sense of interconnection type cigarette, one, code-shaped cigarette sense (intelligent cigarette sense), this kind of cigarette sense needs supporting exclusive main frame to use, and adopt two lines bus wiring, DC24V powers; Backward main frame of reporting to the police outputs signal, on-the-spot without acousto-optic.Be mainly used in fire-fighting system, such as, hotel, KTV, factory building, community, waits in large place, plays overall preventive effect.
Switching value cigarette sense (sense of relay cigarette), this type of cigarette sense also needs supporting associated host to use, but mainly can provide 9V-28V DC voltage, and cigarette is sympathetic can normally work, to main frame output switch amount signal after on-the-spot sound and light alarm.Be mainly used in telecommunication path base station, room environment monitoring, Smart Home, building talkback etc., mainly individual plants and field prevented and coordinate monitoring.
Multi-thread cigarette sense (traditional cigarette sense), can join any multi-thread main frame and use, to drag down voltage system to main frame alerting signal after warning, on-the-spot without acousto-optic.Bus fire-fighting system is only approved in domestic fire-fighting, therefore multiple-wire system mainly exports, and is the little place being applicable to villa and so on.
Wireless smoke sense is one of independent cigarette sense this version of upgrading, more than independent cigarette sense functions of a wireless signal emission.General is also 9V powered battery, and wireless frequency is generally 315M (domestic main flow, abroad mainly 433M, selects to depend on main frame), and supporting wireless host uses.Due to the impact being subject to the factors such as distance of wireless signal, therefore field of employment is quite restricted.
The place that smoke detector is suitable for simply is introduced down: the hall, bedroom, office etc. of restaurant, hotel, teaching building, office building; Computer room, communication machine room, movie or television projection room etc.; Stair, aisle, elevator(lift) machine room etc.; Stack room, file store etc.; There is the place of electrical fire danger.
But the radiation problem of Ion Smoke Sensor cannot solve for a long time, and the dust accretions of photoelectric smoke sensor makes its Frequent Troubles always.The appearance of plastic optical fiber sensor makes radiation and dust accretions problem be resolved.
