2nd I/O interfaces of connection.
The processing component 106 judges the on off state of the box cover by the 2nd I/O interfaces, to control the confession
Whether power supply 102 exports electric energy and supplies electricity to the active electronic device 104.
At this point, if the signal of the 2nd I/O interfaces of detection is high level, it can determine whether box cover still in opening state, machine
103 exportable enable signal of tool construction of switch is to enabled interface, even if at this point, the first I/O interfaces of the processing component 106 exist
Also the enabled interface need not be persistently outputed enable signal to when processing component 106 is in operating mode, only latch enabled letter
Number.
When the level signal for detecting the 2nd I/O interfaces becomes low level from high level, it can be determined that box cover is closed at this time,
When mechanical switch structure 103 can not output enable signal to enabled interface.If processing component 106 is still in Working mould at this time
Formula, then the enabled interface is outputed enable signal to by the first I/O interfaces, ensure that power supply control chip 105 can still export confession
The electric energy that power supply provides is to processing component 106 and active electronic device 104, to ensure that processing component 106 can normal work
Make.
In the present embodiment, the control powered to active electronic device is further realized by processing component, and pass through detection
The on off state of the level state detection box cover of mechanical switch structure output signal, ensure that processing component can work normally
Meanwhile further saving system power.
