Boot process:

When the user sits on the computer chair next to the computer, the pressure sensor 111 arranged on the seat cushion of the computer bears pressure and outputs a voltage change, and the first controller 113 records the state of the force and the state after monitoring the voltage change The duration is maintained, and the state parameter and the duration parameter are sent to the signal receiver 121 through the signal transmitter 112 . When the signal received by the signal receiver 121 shows that the seat cushion bears pressure and keeps it for a certain period of time (exceeding the preset period of time), it means that a user is sitting on the computer seat. The level signal of the level converter 125 determines whether to start the machine. Specifically, if the signal sent by the level shifter 125 is at a high level, it means that the computer is currently in a power-on state. At this time, the judger does not send a power-on signal, and the electronic switch 122 does not act (keeps the current on-off state); If the signal sent by the level shifter 125 is low level, it means that the computer is currently not powered on. At this time, the judger sends a power-on signal to the electronic switch 122, and the electronic switch 122 is closed, and then the power switch 213 is started to control the computer to start.

Shutdown process:

When the user leaves the computer seat next to the computer, the pressure sensor 111 arranged on the seat cushion of the computer seat does not bear pressure and outputs a voltage change, and the first controller 113 records the force state and the state after monitoring the voltage change The duration is maintained, and the state parameter and the duration parameter are sent to the signal receiver 121 through the signal transmitter 112 . When the signal received by the signal receiver 121 indicates that the seat cushion is not under pressure, it means that the user has left the computer chair. The parameter determines whether to shutdown. Specifically, if the signal sent by the level converter 125 is a low level, it means that the computer is currently in a shutdown state. At this time, the judger does not send a shutdown signal; if the signal sent by the level converter 125 is a high level, And when the duration parameter received by the signal receiver 121 exceeds the preset duration, the judging device sends a shutdown signal to the USB interface 211 through the USBPHY. interface) will execute the shutdown action, which is a normal shutdown; if the signal sent by the level converter 125 is high level, and the duration parameter received by the signal receiver 121 is less than the preset duration, it means that the user temporarily leaves the seat, At this time, the judging device does not send a shutdown signal, and the computer remains on.

In the embodiment of the present utility model, the first controller obtains the current stress state of the seat cushion of the computer chair through the pressure sensor, and sends a signal to the signal receiver through the signal transmitter, and the second controller according to the signal received by the signal receiver The signal and the current state of the indicator light can be turned on by controlling the power switch through the electronic switch or shutting down by controlling the shutdown program of the computer through the USB interface, so as to achieve the purpose of automatic switching on and off.
