Embodiment Construction

[0066] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0067] In related technologies, an automatic alarm device triggers an alarm when a vibration signal is detected. However, sound can often also generate vibrations. Therefore, this automatic alarm device is often too sensitive to environmental sounds and often generates false alarms. The embodiment of the invention provides an improved alarm device. figure 2 is a structural block diagram of an alarm device according to an embodiment of the present invention, such as figure 2 As shown, the warning device includes:

[0068] Vibration sensor 22, used for detecting vibration signal;

[0069] Sound sensor 24, is used for collecting ambient sound;

[0070] The processor 26, coupled to the vibration s...

Abstract

The invention provides an alarming method and an alarming device. The alarming method comprises the steps of: detecting a vibration signal; and judging whether acquired environmental sound satisfies the alarming conditions, if so, triggering an alarm. The alarming device comprises a vibration sensor for detecting the vibration signal, a sound sensor for acquiring the environmental sound, and a processor for judging whether the environmental sound acquired by the sound sensor satisfies the alarming conditions in the case that the vibration sensor detects the vibration signal; and if the environmental sound satisfies the alarming conditions, the alarm is triggered. The alarming method and the alarming device solve the problem of frequent occurrence of wrong alarming of an automatic alarming device in the prior art, and effectively reduces the wrong alarming of the alarming device so as to reduce the noise pollution caused by the wrong alarming.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to an alarm method and device. Background technique [0002] In recent years, the number of cars owned has been increasing with the development of the economy. However, because cars are expensive, easy to resell, and easy for car thieves to escape, cars have been one of the favorite targets of thieves for more than a hundred years. Research shows that in the United States alone, a car is stolen every 20 seconds. [0003] In order to prevent automobiles from being stolen, many automobiles are equipped with automatic warning devices, which can send effective warning signals. When the automatic alarm device finds a suspected car theft, most of the automatic alarm devices will sound the horn, flash the headlights, etc. to send out an alarm. Many automatic alarm devices can even send out a variety of sharp alarm sounds. A lot of noise will make people pay attention When the...
