Alarm information sending method, intelligent lamp, computer equipment and storage medium

The embodiment of the invention provides an alarm information sending method, an intelligent lamp, computer equipment and a storage medium. The alarm information sending method is applied to the intelligent lamp, the intelligent lamp comprises an ultrasonic transmitting unit and an ultrasonic receiving unit, and the method comprises the steps that under the condition that the intelligent lamp is lightened, the ultrasonic transmitting unit is used for sending an ultrasonic detection signal in a space; receiving an ultrasonic feedback signal by using an ultrasonic receiving unit; the ultrasonic feedback signal is an ultrasonic signal emitted by an object in a space after receiving the ultrasonic detection signal; recording static duration when the frequency change of the ultrasonic feedback signal is smaller than a preset threshold value; the static duration is used for representing the duration of no action or tiny action; and when the static duration is greater than a preset duration, sending out alarm inform
