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 present invention is applicable to the field of security, and provides an open fire alarm detection method, device, smoke alarm and storage medium. The method includes the following steps: when it is detected that the current smoke concentration satisfies the set concentration threshold, the smoke alarm The current detection cycle of the device is adjusted to a fast detection cycle to speed up the detection frequency of the smoke concentration; according to the detected smoke concentration change and the corresponding time, the smoke concentration increase rate is obtained; when the smoke concentration is determined according to the smoke concentration increase rate. When an open flame occurs, reduce the smoke alarm threshold of the smoke alarm. The embodiment of the present invention can identify the smoke generated by the open fire in time, improve the alarm sensitivity of the smoke alarm against the open fire, and can alarm in advance or quickly, leaving more escape time and ensuring the safety of personnel.

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...
