Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] The embodiment of the present invention shortens the smoke detection period of the smoke alarm when smoke is generated, and judges whether the smoke is generated by an open flame according to the change trend of the smoke concentration. The alarm sensitivity of the alarm makes the smoke alarm alarm in advance.

[0024] figure 1 The implementation process of the open flame alarm detection method provided by the embodiment of the present invention is shown, and the details are as follows:

[0025] In step S101 , when it is detected that the current smoke concentration meets the set concentra...

Abstract

The invention relates to the field of security and protection and provides an open fire alarming detection method and device, a smoke alarm and a storage medium. The open fire alarming detection method comprises the following steps that when it is detected that the current smoke concentration meets a set concentration threshold, a current detection cycle of the smoke alarm is adjusted to be a rapid detection cycle, and the detection frequency of the smoke concentration is increased; the smoke concentration increasing rate is obtained according to the detected smoke concentration variable quantity and the corresponding time; and when it is judged that smoke is generated by an open fire according to the smoke concentration increasing rate, and a smoke alarming threshold of the smoke alarm isdecreased. The smoke generated by the open fire can be recognized in real time, the alarming sensitivity of the smoke alarm specific to the open fire is improved, advanced or rapid alarming can be conducted, the more escape time is set aside, and personnel safety is ensured.

Description

technical field [0001] The invention belongs to the field of security protection, and in particular relates to an open fire alarm detection method, device, smoke alarm and storage medium. Background technique [0002] Smoke will be generated when the object burns. The photoelectric smoke alarm detects the concentration of smoke through the receiving intensity of the light signal. When the concentration exceeds the alarm threshold, the fire alarm will be activated, otherwise, the fire alarm will not be activated. In real life, the smoke produced when a fire breaks out is more complicated, for example, open flames such as newspapers and plastic foam spread quickly. However, if the alarm is performed simply according to the alarm threshold set by the smoke alarm, it may cause the alarm to be too late, lose the effective timing of the alarm, and delay the best time for escape. Therefore, how to quickly detect that the smoke is produced by an open flame according to the smoke si...
