the second switch 52 has an S pin and an OE pin, which are connected when both the S pin and the OE pin are low;
when the third switch 53 receives the high level signal, the third switch 53 is turned on;
the first switch 51 is used for a CPU (central processing unit) of a keyboard and a tablet personal computer, an S pin of the first switch 51 is connected with the opening and closing cover detection Hall switch 42 through an inverter 54, and an OE pin of the first switch 51 is connected with the third switch 53;
the second switch 52 is used for connecting a USB port of the keyboard and the tablet personal computer, an S pin of the second switch 52 is connected with the reverse plug identification Hall switch 41 through the inverter 54, and an OE pin of the second switch 52 is connected with the third switch 53;
the third switch 53 is used for connecting the tablet computer, the reverse plug identification hall switch 41, the first switch 51, the second switch 52 and the tablet computer mode change-over switch 55;
the tablet mode changeover switch 55 is connected to the tablet.
In particular, tablet mode switch 55, in one particular embodiment, may be implemented by a USB ID,
thus, in one embodiment, a device for positive and negative plug identification control may be as shown in fig. 2.
Therefore, when the flat plate and the disk key are inserted to be opened, the USB signal of the keyboard CPU is correspondingly connected with the analysis end USB1 signal path, the USB signal of the keyboard USB port is correspondingly connected with the flat plate end USB2 signal path, and the USB ID sends low-level signals to the first switch, the second switch and the third switch. Under the condition, the magnetism of the magnet is not detected on the opening-closing cover detection Hall switch and the reverse plug identification Hall switch, one path of a high-level signal output by the opening-closing cover detection Hall switch is directly supplied to the IO of the panel CPU, the panel IO receives the high level to be considered as a normal working state, the other path of the high-level signal is supplied to the first switch on the USB1 path through an inverter, the switch is connected and communicated when the S pin and the OE pin of the first switch are both low level, and the keyboard CPU is normally connected with the panel USB1 path.
Specifically, the inverter functions as: outputting a low level signal when receiving a high level signal; when receiving the low level signal, a high level signal is output.
The reverse plug identification Hall switch outputs a high-level signal, one path of the high-level signal is directly fed to the USB ID, so that the third switch is turned on (specifically, the third switch is an inverter, the reverse plug identification Hall switch outputs the high-level signal, the USB ID receives the low-level signal after the inversion of the third switch), the USB ID pin of the panel CPU detects the low level to set the system into a desktop mode, the other path of the high-level signal is fed to the second switch on the USB2 path through the inverter, the switch is connected and turned on when the S pin and the OE pin of the second switch are both low levels, and at the moment, the USB port on the keyboard is normally connected with the panel USB2 path. Therefore, when the computer is inserted positively, the first switch, the second switch and the third switch are all turned on, the keys on the keyboard and the USB port are all functional, and the computer is in a desktop mode.
When the panel and the disk key are reversely inserted, because the definition of POGOP IN is that USB signals are symmetrically arranged, the POGOP IN is changed into a keyboard end USB port signal which is correspondingly connected with a panel end USB1 channel, a keyboard CPU is connected with a panel USB2 channel, a switch of the USB1 channel is communicated with the front plug, but an S2 switch on the USB2 channel and an S3 switch on the USB ID signal are changed from high to low due to the fact that a reverse plug identification Hall switch detects a magnet which is reversely inserted, the second switch and the third switch are turned off, at the moment, the USB2 channel connected with CPU signals on the keyboard is turned off, and a keyboard key is not enabled, therefore, the reverse plug identification Hall switch outputs a low-level signal through the third switch, the signal detected by the USB ID on the panel CPU is a high-level signal, the signal detected by the CPU is changed from low to high, and at the moment, the CPU sets the system into a PAD mode. Therefore, the keyboard keys are not functional during reverse insertion, the USB port is functional, and the system is in a PAD mode.
