Embodiment Construction

[0031] Embodiments of the method and system for controlling the voice-activated switch and the voice-activated switch of the present invention will be described below with reference to the accompanying drawings.

[0032] figure 1 It is a flow chart of the voice control switch control method of an embodiment. Such as figure 1 As shown, the voice control switch control method may include the following steps:

[0033] S1, acquiring a plurality of audio signal samples, sampling each audio signal sample according to a preset sampling frequency, and acquiring several sample points corresponding to each audio signal sample;

[0034] In this step, the audio signal samples may include a control signal for controlling the voice-activated switch, and may also include noise (for example, applause noise generated by clapping, and speaking noise generated by speaking). The control signal may be applause or a sound signal with a specific attribute, for example, a rhythmic beating sound. ...

Abstract

The invention relates to a sound control switch control method and system and a sound control switch. The method comprises the following steps: obtaining a plurality of audio signal samples, sampling each audio signal sample according to a preset sample frequency, and obtaining a plurality of sample points corresponding to each audio signal sample; detecting the amplitude of each sample point of each audio signal sample, and calculating the slope of the sample point amplitudes of the corresponding audio signal sample according to the amplitudes; comparing the slope and a pre-stored reference slope, and obtaining a time difference between the adjacent audio signal samples through calculation if the slope is greater than the reference slope; and controlling a sound control switch to act if the time difference satisfies a preset time constraint condition. The sound control switch control method and system and the sound control switch can effectively eliminate environment interference, reduce misoperation, and save electric energy.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a voice control switch control method, system and voice control switch. Background technique [0002] The sound-activated switch is an energy-saving electronic switch that uses sound effects to activate the pickup to perform sound-electric conversion to control the opening of electrical appliances under specific ambient light, and can automatically disconnect the power supply after a delay. Existing control methods for voice-activated switches generally include two types: [0003] One is that when the sound sensor receives the sound signal, the controller controls the action of the sound-activated switch to close the sound-activated switch, and the electrical appliance is connected to the external power supply through the closed voice-activated switch, and the external power supply supplies power to the electrical appliance. This control method is easily disturbed b...
