The processor 1 is realized by using a single-chip microcomputer.

Working process: set the time for computer startup and shutdown by timer 2, when the startup time arrives, timer 2 sends a startup signal, processor 1 controls the computer switch 7 by executing the control circuit 6 to realize the startup operation; when the shutdown time arrives , the timer 2 sends a shutdown signal, and the processor 1 controls the computer switch 7 through the execution control circuit 6 to realize the shutdown operation.

Embodiment 2: This embodiment is a further description of Embodiment 1. It also includes a display 5 , and the display instruction output end of the processor 1 is connected to the display instruction input end of the display 5 .

The display 5 is used for displaying the preset power-on and power-off times in the timer 2 .

Embodiment 3: This embodiment is a further description of Embodiment 1 or 2. It also includes a radio frequency circuit 3 , and the switch instruction output end of the radio frequency circuit 3 is connected to the switch instruction input end of the processor 1 .

The wireless radio frequency circuit 3 is realized by using a radio frequency chip whose model is nRF2401.

The computer timing switch device described in this embodiment is provided with a wireless radio frequency circuit 3, and people can use a remote controller to send a switch command to the computer, so that people do not need to go to the computer to manually shut down the computer when they are tired and ready to rest. Wait until the set time and then shut down, wasting electric energy in vain.

Specific embodiment four: present embodiment is further explanation to embodiment one, two or three, and it also comprises short message sending circuit 8, and the short message sending instruction output end of processor 1 links to each other with the short message sending instruction input end of short message sending circuit 8 .

When people use the computer, they have already set the shutdown time. When they go out because they are in a hurry, they do not manually shut down the computer. When the preset time of timer 2 arrives, the computer will automatically shut down. mobile phone to send a text message.
