The first end of the pressure sensor Y1 and the first end of the first resistor R1 are both electrically connected to a power supply terminal, and the second end of the pressure sensor Y1 and the first end of the second resistor R2 are both electrically connected to a control terminal of the first switching tube VT 1. The input terminal of the first switching transistor VT1 and the second terminal of the first resistor R1 are both configured to be electrically connected to the electronic system 400, and the output terminal of the first switching transistor VT1 and the second terminal of the second resistor R2 are both grounded.
Specifically, when the electronic system 400 is in the sleep state, the voltage at the common terminal of the pressure sensor Y1 and the second resistor R2 is at a low level (lower than the turn-on voltage of the first switching transistor VT 1), the first switching transistor VT1 is in the off state, and the second terminal of the first resistor R1 outputs a high level signal to the electronic system 400.
When the electronic system 400 needs to be awakened, a worker presses or taps the cap body 100, the deformation resistance of the pressure sensor Y1 becomes small, the voltage of the common end of the pressure sensor Y1 and the second resistor R2 rises, the first switching tube VT1 is turned on, and the second end of the first resistor R1 outputs a low-level signal (a first awakening signal) to the electronic system 400. After receiving the low level signal, the electronic system 400 is switched from the sleep state to the working state, so as to wake up the electronic system 400.

When the piezoelectric ceramic piece is in a non-working state, the power consumption of the piezoelectric ceramic piece is zero. When a worker knocks the cap body 100, the width of the first wake-up signal generated by the piezoelectric ceramic piece is about 1 millisecond, the driving current of the first wake-up signal is about 10 microamperes, and the energy-saving effect can be achieved by using the piezoelectric ceramic piece. The piezoelectric ceramic sheet is mounted on the inner side of the cap body 100 to protect the piezoelectric ceramic sheet. The current of the MOS tube in the working state is about 2 microamperes, the power consumption is very low, and the energy-saving effect can be realized.
For example, 20 mm piezoceramic wafers may be used.
Fig. 3 shows a schematic circuit connection diagram of a vibration wake-up unit 200 according to another embodiment of the present application. Referring to fig. 3, the vibration wake-up unit 200 includes a third resistor R3, a first capacitor C1, and a vibration switch SW 1.
The first end of the third resistor R3 is electrically connected to a power source, and the second end of the third resistor R3, the first end of the first capacitor C1 and the first end of the vibration switch SW1 are all used for electrically connecting to the electronic system 400. The second terminal of the first capacitor C1 and the second terminal of the vibration switch SW1 are both grounded.
Specifically, when the electronic system 400 is in the sleep state, the vibration switch SW1 is in the off state, and the second end of the third resistor R3 outputs a high-level signal to the electronic system 400.
When it is desired to wake up the electronic system 400, a worker presses or taps the cap 100, which causes the vibration switch SW1 to turn on. When the vibration switch SW1 is turned on, the second terminal of the third resistor R3 outputs a low level signal (the first wake-up signal) to the electronic system 400. After receiving the low level signal, the electronic system 400 is switched from the sleep state to the working state, so as to wake up the electronic system 400.
For example, the vibration switch may be a SW-18015P type spring vibration switch.
It should be noted that when the worker strikes the cap body 100, the vibration switch SW1 is turned on for about 1 millisecond, the driving current is about 10 microamperes, and the energy saving effect can be achieved by using the vibration switch SW 1.
Fig. 4 is a schematic circuit diagram of the barrier wake-up unit 300 according to an embodiment of the present disclosure. Referring to fig. 4, the barrier wake-up unit 300 includes a fourth resistor R4, a fifth resistor R5, a second capacitor C2, and an infrared sensor U1.
A first end of the fourth resistor R4 and a first end of the fifth resistor R5 are both electrically connected with a power supply end; the first control end of the infrared sensor U1 is electrically connected with the second end of the fourth resistor R4, the second control end of the infrared sensor U1 is grounded, the first action end of the infrared sensor U1, the second end of the fifth resistor R5 and the first end of the second capacitor C2 are all used for being electrically connected with the electronic system 400, and the second action end of the infrared sensor U1 and the second end of the second capacitor C2 are all grounded.
Specifically, when the electronic system 400 is in the sleep state, the diode between the first control terminal and the second control terminal of the infrared sensor U1 emits light, but the first active terminal and the second active terminal of the infrared sensor U1 cannot be conducted, and at this time, the second terminal of the fifth resistor R5 outputs a high level signal to the electronic system 400.
When it is desired to wake up the electronic system 400, the worker blocks his hand over the infrared sensor U1 and the light is reflected back. The first and second terminals of the infrared sensor U1 are turned on after receiving the emitted light, and the second terminal of the fifth resistor R5 outputs a low level signal to the electronic system 400. After receiving the low level signal, the electronic system 400 is switched from the sleep state to the working state, so as to wake up the electronic system 400.
For example, the infrared sensor U1 may be embedded on the outside of the cap 100, with the probe of the infrared sensor U1 protruding outward and no higher than the outside surface of the cap 100. The infrared sensor U1 can be ensured to emit infrared light normally and receive the emitted light.
Fig. 5 is a schematic circuit diagram of the barrier wake-up unit 300 according to an embodiment of the present disclosure. Referring to fig. 5, the barrier wake-up unit 300 further includes a sixth resistor R6 and a second switching tube VT 2.

Specifically, the output terminal of the electronic system 400 may output a control signal to make the second switching tube VT2 in a conducting state, so as to drive the light emitting diode between the first control terminal and the second control terminal of the infrared sensor U1 to emit light.
When it is desired to wake up the electronic system 400, the worker blocks his hand over the infrared sensor U1 and the light is reflected back. The first and second terminals of the infrared sensor U1 are turned on after receiving the emitted light, and the second terminal of the fifth resistor R5 outputs a low level signal to the electronic system 400. After receiving the low level signal, the electronic system 400 is switched from the sleep state to the working state, so as to wake up the electronic system 400.
The electronic system 400 controls the working state of the shielding wake-up unit 300 through the second switching tube VT2, and when the electronic system 400 is in the working state, the electronic system 400 controls the second switching tube VT2 to be in the cut-off state, so that the shielding wake-up unit 300 is in the non-working state, the power consumption is reduced, and the energy-saving effect is realized.
Illustratively, the control signal output by the output terminal of the electronic system 400 is a PWM signal, and the PWM signal has a duty cycle of 0.001 and a period of 1 s.
Specifically, when the electronic system 400 is in the sleep state, the electronic system 400 transmits a PWM signal with a duty cycle of 0.001 and a period of 1s to the control terminal of the second switching transistor VT 2. When the electronic system 400 needs to be woken up, the worker only needs to stop his/her hand over the infrared sensor U1 for 1s, so that the blocking wake-up unit 300 can generate a second wake-up signal (low level signal). After receiving the low level signal, the electronic system 400 is switched from the sleep state to the working state, so as to wake up the electronic system 400.
Illustratively, the infrared sensor U1 is an infrared photoelectric sensor of TCRT5000 model, and when the supply voltage is 3.3V, the average standby current of TCRT5000 is 3 microamperes, so the infrared photoelectric sensor of TCRT5000 model has the characteristics of low power consumption, and can realize the effect of energy saving.
For example, the second switching transistor VT2 is an MOS transistor, and when the MOS transistor is in an operating state, the current is about 2 microamperes, the power consumption is low, and the energy saving effect can be achieved.
