Operation principle of the invention is：Zero-power is a kind of new approaches of super low-power consumption circuit design, can allow certain mould
Power consumption of the block in down time is zero, without being its special design electric power management circuit.
When the TXD pins (pin 3) of PC export logic 1, voltage is -10V, V1 cut-offs, the RXD pins of single-chip microcomputer
It is high level by R2 pull-up.When realizing computer hair logic 1, single-chip microcomputer receives logic 1.
When the TXD pins (pin 3) of PC export logical zero, voltage is+10V, V1 saturations, the RXD pins of single-chip microcomputer
It is pulled to low level.When realizing computer hair logical zero, single-chip microcomputer receives logical zero.
Be logic 1 when TXD sends idle, even and if data continuously transmit, also at least stop bits is logic 1, and this is just
Ensure that in a byte time interval, TXD at least has the appearance of -10V voltages.This -10V voltage is stored by VD1 by C1,
Used for subsequent conditioning circuit.
When the TXD pins of single-chip microcomputer export logic 1, voltage is -3.3V, V2 cut-offs, the RXD pin quilts of computer
R4 is drop-down for -10V.When realizing single-chip microcomputer hair logic 1, computer receives logic 1.
When the TXD pins of single-chip microcomputer export logical zero, voltage is 0V, V2 saturations, and the RXD pins of computer are by R4
It is VCC to pull up.And VCC is higher than 3V, when realizing single-chip microcomputer hair logical zero, computer receives logical zero.
