It should be noted that the CLRn pin in the first flip-flop 133 is an asynchronous reset pin, and the PREn pin in the first flip-flop 133 is an asynchronous set pin.
Specifically, referring to fig. 1, in conjunction with fig. 2 to 4, after receiving the sleep command, the processor unit 400 sets a time for sending the wake-up signal to the clock unit 120 through the serial clock pin SCL and the serial data pin SDA of the clock chip 121, and sends a high level to the first resistor R1 of the isolation subunit 131 so as to turn on the first transistor Q1; the first triode Q1 is turned on to make the CLRn pin in the first flip-flop 133 in the trigger switch subunit 132 be at a low level; the CLRn pin of the first flip-flop 133 is at a low level to enable the first flip-flop 133 to trigger the state 2, and the output pin Qn of the first flip-flop 133 is at a high level, so that the second transistor Q2 is turned on; the second transistor Q2 is turned on to make the turn-off pin of the second DC-DC power supply module in the second output management unit 210 low, thereby turning off the second output management unit 210.
The clock unit 120 sends a wake-up signal to the switch unit 130 after the time comes, so that the PREn pin in the first flip-flop 133 in the switch unit 130 is at a low level; the first flip-flop 133 triggers the state 1 to make the output pin Qn of the first flip-flop 133 be low, so that the second transistor Q2 is not turned on; the second transistor Q2 is turned off, so that the off pin of the second DC-DC power module in the second output management unit 210 is pulled up to a high level, thereby turning on the second output management unit 210; the second output management unit 210 supplies power to the underwater acoustic communication circuit 220 to wake up the underwater acoustic communication device.
Since the underwater acoustic communication device only operates in the standby module 100 when the second output management unit 210 is turned off, and since the first DC-DC power module in the first output management unit 110 reduces the voltage of the power supply module 300 to 3V and supplies the reduced voltage to the standby module 100, unnecessary power consumption is reduced, and thus, the clock unit 120 is configured to transmit a wake-up signal, and the underwater acoustic communication device is woken up after the time comes, so that the underwater acoustic communication device can wake up the underwater acoustic communication device at a set time, unnecessary power consumption is reduced, and the operating time of underwater operation of the underwater acoustic communication device is prolonged.

Further, referring to fig. 3, in conjunction with fig. 1-2, the trigger switch subunit 132 further includes a fifth resistor R5 and a second transistor Q2; a first end of the fifth resistor R5 is connected to the output pin Qn of the first flip-flop 133, and a second end of the fifth resistor R5 is connected to the base of the second transistor Q2; the collector of the second transistor Q2 is connected to the second output management unit 210.
Specifically, when the first flip-flop 133 triggers state 3, the output pin Qn of the first flip-flop 133 is at a low level, so that the second transistor Q2 is rendered non-conductive; the second output management unit 210 normally supplies power to the underwater acoustic communication circuit 220 so that the underwater acoustic communication apparatus normally operates.
When the CLRn pin of the first flip-flop 133 changes to a low level and the first flip-flop 133 triggers the state 2, the output pin Qn of the first flip-flop 133 is at a high level, so that the second transistor Q2 is turned on; the second transistor Q2 is turned on to make the off pin of the second DC-DC power supply module low, thereby turning off the second output management unit 210; the second output management unit 210 is turned off to put the underwater acoustic communication apparatus into a sleep state.

Since the clock unit 120 is sending the wake-up signal time, the pre pin of the first flip-flop 133 is to be kept in a high state, and the seventh resistor R7 can pull up the pre pin of the first flip-flop 133 to be in a high state.
Further, as shown in fig. 1 to 4, the present invention provides a wake-up method for an underwater acoustic communication device, where the method is applied to any one of the above-mentioned underwater acoustic communication devices, and the method includes:
