Further, the ultrasonic device includes an ultrasonic transmitter 11 and an ultrasonic receiver 12, the ultrasonic transmitter is used for transmitting an ultrasonic signal to the outside; the ultrasonic receiver is connected with the control circuit and used for receiving ultrasonic signals reflected back when people move, generating electric signals and sending the electric signals to the control circuit. Preferably, the ultrasonic apparatus further includes a controller 13 for controlling the ultrasonic transmission of the transmitter, determining whether the receiver receives the ultrasonic wave and the magnitude of the received ultrasonic signal, and generating the electric signal when the received ultrasonic signal is greater than a threshold value. Optionally, the ultrasonic apparatus 1 further comprises a power supply part 14, which is powered by an external direct current power supply with a voltage of DC12V + -10% or 24V + -10% and supplies power to the ultrasonic apparatus via an internal voltage stabilizing circuit.
And the control circuit 2 is used for starting the unmanned self-service system when receiving the electric signal and closing the unmanned self-service system when not receiving the electric signal. Further, the control circuit comprises a triode 21 and a relay 22, the base electrode of the triode is connected with the ultrasonic receiver, the emitting electrode of the triode is grounded, the collector electrode of the triode is connected with one end of the relay, the other end of the relay is connected with a voltage Vcc (5v), and the contact of the relay is located on the power line of the unmanned self-service system. Optionally, a first resistor (100 Ω) is connected between the collector of the triode and the relay, and two branches are connected in parallel with the relay, where one branch is a diode and the other branch is a capacitor and a second resistor (100 Ω) connected in series to protect the relay.
When an electric signal is received, the base of the three-level tube is at a high level, and a relay contact loop is switched on, so that the unmanned self-service system is powered on and started; when the electric signal is not received, the base of the tertiary pipe is at a low level, and the relay contact circuit is disconnected, so that the unmanned self-service system is powered off and closed.

When personnel activities exist in the corresponding areas, the ultrasonic signals are reflected back, and the vibrators of the ultrasonic receivers generate corresponding mechanical vibration and convert the mechanical vibration into electric signals to be output. In order to avoid misoperation, weak reflected waves are adjusted in a dead zone range through ultrasonic wave transmitting power setting, so that receiver action is not caused; alternatively, by using an integrated circuit as a controller, the ultrasonic transmission of the transmitter is controlled, and it is determined whether the ultrasonic signal is received by the receiver and the magnitude of the received ultrasonic signal, and when the signal magnitude exceeds a threshold value, an electric signal is output.
The base electrode of the triode has high level when receiving an electric signal, the coil of the relay is electrified under the action of the triode amplifier, and the contact circuit of the relay is connected under the action of suction force, so that the circuit of the unmanned self-service system is electrified. Under the condition that the ultrasonic signal cannot be detected, the ultrasonic receiver cannot send an electric signal, the base of the triode is at a low level, the relay loses power, the magnetism of the coil disappears, and therefore the power supply of the unmanned self-service system is cut off and the unmanned self-service system stops working.
