Problems solved by technology

The photoelectric fire smoke alarm using the scattering principle still has defects: non-fire smoke particles also scatter light, which leads to false alarms; some fire smoke particles do not have obvious light scattering, so it is not easy to trigger the alarm devi

Abstract

The invention relates to the technical field of smoke alarms, in particular to a smoke alarm and a method thereof. The smoke alarm comprises a maze; a photosensitive sensor and the light-emitting tubeI which are arranged in the maze, the two sides of the photosensitive sensor and the two sides of the first light-emitting tube are provided with light barriers used for preventing emitted light of the first light-emitting tube from irradiating the photosensitive sensor. A second light-emitting tube is further installed in the maze, and emitted light of the second light-emitting tube penetrates through light inlets formed by the light barriers on the two sides of the photosensitive sensor and directly irradiates the photosensitive sensor. According to the photoelectric fire smoke alarm, by introducing the other-dimensional information except the light scattering effect of the particles strongly related to the smoke concentration and the smoke type and the light shielding effect of the particles, the smoke recognition effect is greatly improved, the alarm precision of the photoelectric fire smoke alarm can be effectively improved, and the missing alarm rate and the false alarm rate ofthe photoelectric fire smoke alarm are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of smoke alarms, in particular to a smoke alarm and a method thereof. Background technique [0002] Fire alarms are an important part of the fire protection field, and photoelectric fire smoke alarms are the mainstream of the market. The photoelectric fire smoke alarm is designed based on the principle of light scattering by smoke particles. The photoelectric fire smoke alarm using the scattering principle still has defects: non-fire smoke particles also scatter light, which leads to false alarms; some fire smoke particles do not have obvious light scattering, so it is not easy to trigger the alarm Detector alarm, which led to the missed report of fire smoke. Therefore, the two core technical indicators of the photoelectric fire smoke alarm are whether the false alarm rate and the false alarm rate are excellent. [0003] The structure of the traditional photoelectric fire smoke alarm mainly includes: a ph...
