The use of fire is one of the most important inventions of human beings, but once the fire is developed after losing control, the fire can seriously threaten the lives, properties and natural environment of people. Because of the sudden and frequent occurrence of a fire, it causes damage next to drought and flood disasters. Since human history, people are constantly wandering around the edges of combustion utilization and fire control, and with the progress of human civilization, the fire fighting is gradually developed from passive fire fighting to active fire detection and prevention, and too much damage and loss are prevented.
Fire detection has been developed in various fields and in various technical fields, such as smoke detection, temperature detection, etc., which detect a fire by using smoke, flame, and temperature of the fire, respectively. The smoke alarm is a fire-fighting alarm device which can realize fire early warning by detecting the concentration of smoke particles in the early stage of a fire.

With the emphasis of the country and the family on fire accident prevention, the application of the smoke alarm is more and more extensive, but the problem of false alarm of the smoke alarm is a technical problem limiting the development of the smoke alarm.

The secondary judgment is carried out before the reset instruction is sent, so that the situation that the smoke alarm is mistakenly reset when a fire really occurs indoors is avoided, unnecessary property loss of a user is reduced, and the accuracy of fire security is improved.
In the embodiment, under the condition that the detection distance is judged to be not less than the preset distance, a communication module in the smoke alarm is used for sending alarm information; or under the condition that the duration time does not exceed the preset time value, the alarm information is sent by using a communication module in the smoke alarm.
When the detection distance is confirmed to be not smaller than the preset distance, or the duration time that the detection distance is smaller than the preset distance does not exceed the preset time value, the fact that a fire really occurs indoors is determined, alarm information can be sent to preset communication equipment through a communication module in the smoke alarm, personnel are informed to conduct fire fighting and disaster relief treatment, property loss of users is reduced, and personal safety of the users is protected.
In some of these embodiments, resetting the smoke alarm to cause the smoke alarm to exit the alarm mode of operation comprises: and sending a reset instruction to a warning module and a distance measuring module in the smoke alarm so as to stop the warning module and the distance measuring module and enable the smoke alarm to enter a low-power-consumption working mode.
