- 7. the answer method of super long standby time acoustic responder system according to claim 6, it is characterised in that：The low work( Consumption pattern is that the power amplifier module of system, simulation receive pretreatment module, single-chip microcomputer on duty and control module and numeral is believed Number processor module is in power-down state, and the low frequency crystal oscillator of only single-chip microcomputer is in running order, and low frequency crystal oscillator shakes Swing device and be used for driving timing device transmitting timing signal, at the end of timing, it is on duty that timer produces interrupt signal wake-up single-chip microcomputer With control module, it is set to start to detect wake-up signal.
- 8. the answer method of super long standby time acoustic responder system according to claim 7, it is characterised in that：The low work( The period T of consumption pattern1It can be carried out according to transmission signal presetting.
