Embodiment Construction

[0010] see figure 1 , a preferred embodiment of the present invention provides a power-on control circuit 100, which is applied to electronic devices such as personal computers and servers to control the power-on of the electronic devices.

[0011] The power-on control circuit 100 includes a microphone 10 , a speech processing circuit 20 , a level conversion circuit 30 , a power switch 40 , an AND gate 50 and a flip-flop 60 . The voice processing circuit 20 , the level conversion circuit 30 , the AND gate 50 and the flip-flop 60 are integrated on the main board of the electronic device.

[0012] To facilitate user control, the microphone 10 can be installed in a control room and electrically connected to the voice processing circuit 20 through a wire. The microphone 10 is used to collect the voice signal of the user, and transmit the collected voice signal to the voice processing circuit 20 .

[0013] The voice processing circuit 20 is used for outputting a high-level signal...

Abstract

The invention provides a startup control circuit applied to electronic devices. The startup control circuit comprises a microphone, a voice processing circuit and a level switching circuit, the microphone is used for collecting the voice of a user, the voice processing circuit comprises a voice operated switch which comprises a voice input pin and a signal output pin, and the voice input pin is electrically connected with the microphone. The voice operated switch is used for identifying the voice and adjusting the wave shape of the voice to output a high level signal through the signal output pin, and after receiving the high level signal output by the signal output pin, the level switching circuit outputs a low level signal to a main board of an electronic device to control the startup of the electronic device. The startup control circuit can control the startup of the electronic device through a voice, and is convenient to use.

Description

technical field [0001] The invention relates to a start-up control circuit, in particular to a sound-activated start-up control circuit. Background technique [0002] At present, most electronic devices such as personal computers (PCs) or servers (Servers) are turned on by mechanical operation of a power switch key, and the key must be operated every time the machine is turned on and off. In addition, because the server is generally not placed near the operation terminal but installed in a special computer room, when it is necessary to switch on and off, professionals often need to come to the computer room to open the cabinet and operate the power switch, which makes the operation more troublesome. Contents of the invention [0003] In view of the above circumstances, it is necessary to provide an easy-to-operate power-on control circuit. [0004] A start-up control circuit, applied to electronic equipment, the start-up control circuit includes a microphone, a voice proc...
