感烟探测器是火灾探测器的一种,在使用过程中有时会发生误报。误报的原因大体上有两种:一是设计因素,如元器件性能不稳定,结构设计不周,造型、布局、安装不尽合理等,这需要通过提高设计水平来减少。二是环境因素,如安装地点的温、湿度变化大,腐蚀气体含量高,粉尘、灰尘、昆虫、水蒸气的凝结等对探头的影响,以及人为造成的有意无意的损坏,大量吸 Smoke detectors are a kind of fire detectors, and false positives sometimes occur during use. There are two main reasons for false positives: First, design factors, such as unstable component performance, poorly designed structures, improper shape, layout, and installation, which need to be reduced by improving the design level. Second, environmental factors, such as installation site temperature and humidity changes, the high content of corrosive gases, dust, dust, insects, water vapor condensation on the probe, as well as man-made damage caused by intentional or unintentional, a lot of suction
