Description
本发明涉及感烟火灾探测技术领域，具体来说是一种烟雾探测器迷宫结构及其烟雾探测方法。The invention relates to the field of smoke detecting fire technology, in particular to a smoke detector labyrinth structure and a smoke detecting method thereof.
光电感烟火灾探测器的工作原理是光电接收管处于反射光照射下产生电信号，当光电发光管发出的光遇到火灾烟雾时产生反光时，光电接收管接收到光信号，经放大，如果达到设定报警阀值，则发出报警信号。在正常无烟的监视状态下，探测器的光敏元件只接收到少量的反射光，在烟雾粒子进入迷宫探测室内时.发光元件发出的光则被烟粒子散射或反射到光敏元件上，并在收到充足光信号时，便发出火灾报警。但是现有的光电感烟火灾探测器对黑烟和白烟的响应敏感度不同，由于白烟对应光反射强度大，接收信号强度大，黑烟对应光反射强度小，接收信号强度弱；现在市场的大部分探测器，为了实现白烟和黑烟均能报警，往往在较弱反射光的强度下设定为报警阀值，这样，很少的白烟就会导致其开始报警，但是需要数量很多的黑烟才会引起报警，从而导致了水蒸汽和灰尘误报，而真正火灾产生的黑烟反而会漏报情况的发生。我国专利申请号CN2005101046075公开了一种立式双向散射感烟探测器迷宫，设有一组锐角发射接收管和一组钝角发射接收管，但是无论黑烟还是白烟，根据该探测器迷宫探测绘制得出的都是上升的曲线，只是其斜率不同，虽然解决了现有探测器对黑烟和白烟的响应敏感度不同的问题，但是仍然无法具体区分是黑烟还是白烟，因此，需要设计一种新型的烟雾探测器迷宫结构及其烟雾探测方法。The working principle of the photo-electrical smoke detector is that the photoelectric receiving tube generates an electric signal under the illumination of the reflected light. When the light emitted by the photoelectric luminous tube is reflected by the fire smoke, the photoelectric receiving tube receives the optical signal and is amplified if When the set alarm threshold is reached, an alarm signal is issued. In the normal smoke-free monitoring state, the photosensitive element of the detector receives only a small amount of reflected light, and when the smoke particles enter the labyrinth detection chamber, the light emitted by the light-emitting element is scattered or reflected by the smoke particles onto the photosensitive element, and When a sufficient light signal is received, a fire alarm is issued. However, the existing photo-electrical smoke detectors have different sensitivity to black smoke and white smoke. Since the white smoke corresponds to a large light reflection intensity, the received signal intensity is large, the black smoke corresponds to a small light reflection intensity, and the received signal strength is weak; Most of the detectors in the market can alarm for white smoke and black smoke, and are often set to alarm thresholds under the intensity of weaker reflected light. Thus, very little white smoke will cause it to start alarming, but it needs A large amount of black smoke will cause an alarm, which will lead to false alarms of water vapor and dust, and the black smoke generated by a real fire will falsely report the situation. China Patent Application No. CN2005101046075 discloses a vertical two-way scattering smoke detector labyrinth, which is provided with a set of acute angle transmitting receiving tubes and a set of obtuse angle transmitting receiving tubes, but whether black smoke or white smoke is drawn according to the detector maze detection All of them are rising curves, but their slopes are different. Although the existing detectors have different sensitivity to black smoke and white smoke, it is still impossible to distinguish whether it is black smoke or white smoke. Therefore, it needs to be designed. A new type of smoke detector maze structure and its smoke detection method.
