A smoke alarm method, device, smoke alarm equipment and storage medium

Abstract

The invention is applicable to the field of security, and provides a smoke alarm method, a smoke alarm device, smoke alarm equipment and a storage medium. The smoke alarm method comprises the steps of: acquiring a compensation value in the smoke alarm equipment; acquiring a smoke value increment in the smoke alarm equipment; determining whether the smoke alarm equipment is in a polluted or attenuated state; if the smoke alarm equipment is in a polluted or attenuated state, correcting a calibration smoke correction value total increment in the smoke alarm equipment based on the polluted or attenuated state to obtain a corrected alarm value increment, wherein the calibration smoke correction value total increment is a difference value between a calibration alarm value and a calibration offset signal value of a smoke alarm; and determining whether the smoke value increment is greater than or equal to the corrected alarm value increment; and sending out alarm information when the smoke value increment is greater than or equal to the corrected alarm value increment. The purposes of preventing false alarms and prolonging service life of products are achieved through compensating form thecalibration smoke correction value total increment according to the compensation value.

Description

technical field [0001] The invention relates to the security field, in particular to a smoke alarm method, device, smoke alarm equipment and storage medium. Background technique [0002] From the perspective of the sensors used, smoke alarms can be divided into ion smoke alarms and photoelectric smoke alarms. Among them, there is an optical maze in the photoelectric smoke alarm, which is composed of a transmitting tube, a receiving tube and a labyrinth chamber. The structure of the labyrinth chamber is composed of relatively complex light reflection, refraction surfaces or ribs. After the smoke enters this special structural cavity, it can reflect the smoke concentration. When there is no smoke, the infrared receiving tube cannot receive the infrared light emitted by the infrared emitting tube. When smoke enters the optical maze, the receiving tube receives the infrared light through refraction and reflection, and the intelligent alarm circuit judges whether the collected sm...
