In the fingerprint module, when the collecting and identifying module does not need to work, the detecting module controls the second switching tube Q2 to be turned off, and when the detecting module does not detect the operation of a user, the detecting module controls the first end and the second end of the second switching tube Q2 to be in an off state through the control end of the second switching tube Q2, so that the current of the first power supply flows to the control end of the first switching tube Q1 through the first resistor R1, and the current of the first power supply flows to the first end of the first switching tube Q1, that is, the current of the first power supply simultaneously flows to the control end and the first end of the first switching tube Q1, so that the voltages of the control end and the first end of the first switching tube Q1 are equal, so that the first switching tube Q1 is turned off, at this time, the first power supply cannot supply power to the collecting and identifying module, and thus the collecting and identifying module is in an inoperative state, therefore, the collection identification module is in a 'dormant' state, and the collection identification module does not consume electric quantity, so that the electric consumption of the collection identification module when the collection identification module does not work is reduced. When the fingerprint needs to be collected and identified by the collecting and identifying module, the detection module detects the operation of the user, the detection module is used for sending a control signal to the control end of the second switch tube Q2 according to the operation of the user, so that the first terminal and the second terminal of the second switch tube Q2 are conducted, when the second switch tube Q2 is conducted, because of the high resistance in the circuit in communication with the first resistor R1, current does not pass through the first resistor R1, the current of the first power supply flows to the first terminal of the first switch tube Q1, so that the voltage of the first terminal of the first switch tube Q1 is higher than the voltage of the control terminal of the first switch tube Q1, so that the first switch tube Q1 is conducted, and the current of the first power supply flows to the collection and identification module, and then make gather the identification module work to make the fingerprint module gather and discern user's fingerprint information through gathering identification module. In the fingerprint module working process, need not gather the identification module during operation gather identification module and be in the off-state, and need gather identification module during operation rethread detection module and carry out "awakening up" to it to can reduce the power consumption of fingerprint module.

Will when the fingerprint module is applied to the fingerprint lock, the power consumption of fingerprint module is less to make the whole power consumption of fingerprint lock less, make the battery module's of fingerprint lock electric quantity more durable.

In order to further reduce the power consumption of the fingerprint module, as shown in fig. 2, in one embodiment, the fingerprint module further includes a second electrical input terminal U3, a second electrical output terminal U4, a third switching tube Q3, a fourth switching tube Q4, a fifth switching tube Q5, a second resistor R2, a third resistor R3, and a fourth resistor R4, the collecting and identifying module (not shown) is connected to the control terminal of the third switching tube Q3, the second electrical input terminal U3 is configured to be connected to a first power supply, the second electrical input terminal U3 is connected to the first terminal of the third switching tube Q3 through the second resistor R2, the second terminal of the third switching tube Q3 is configured to be grounded, the second electrical input terminal U3 is further connected to the control terminal of the fourth switching tube Q4 through the third resistor R3, the second electrical input terminal U3 is further connected to the first terminal of the fourth switching tube Q4, the second end of the fourth switching tube Q4 is used for being grounded through a fourth resistor R4, the second end of the fourth switching tube Q4 is connected with the control end of the fifth switching tube Q5, the second electrical input end U3 is connected with the first end of the fifth switching tube Q5, the second end of the fifth switching tube Q5 is connected with the second electrical output end U4, and the second electrical output end U4 is connected with the detection module. In this embodiment, the collection and identification module is configured to send a control signal to the control terminal of the third switching tube Q3 when the detection module is powered on, so that the third switching tube Q3 is turned on, and thus the fourth switching tube Q4 is turned on, and after the third switching tube Q3 and the fourth switching tube Q4 are turned on, the voltage of the first terminal of the fifth switching tube Q5 is equal to the voltage of the control terminal of the fifth switching tube Q5, so that the fifth switching tube Q5 is turned off, and thus the second electrical input terminal U3 and the second electrical output terminal U4 are turned off, and thus the first power supply of the second electrical input terminal U3 is disconnected from the detection module, and therefore, the detection module may stop working due to power failure. That is, when the collection and identification module is turned on, the detection module is controlled to stop working through the circuit.

In order to further save the power consumption of the fingerprint module, as shown in fig. 1, in one embodiment, the fingerprint module further includes a sixth switch Q6, the collecting and identifying module (not shown) is connected to the control terminal of the sixth switch Q6, the first electrical input terminal U1 is connected to the first terminal of the sixth switch Q6 through the first resistor R1, and the second terminal of the sixth switch Q6 is used for grounding. The acquisition identification module is used for controlling the connection or disconnection of the sixth switching tube Q6 through the control end of the sixth switching tube Q6.

It should be understood that, after the collection and identification module is connected to the first power supply, the collection and identification module will control the detection module to be disconnected from the first power supply, and then the detection module will change the signal sent to the control terminal of the second switch tube Q2, so that the first power supply can stably supply power to the collection and identification module, in this embodiment, the collection and identification module will send a control signal to the sixth switch tube Q6, so that the first terminal and the second terminal of the sixth switch Q6 are turned on, and at this time, the current of the first electrical input terminal U1 does not pass through the first resistor R1, therefore, the voltage of the first terminal of the first switch Q1 is always greater than the voltage of the control terminal of the first switch Q1, the first switching tube Q1 is not turned off due to the turning-off of the second switching tube Q2, so that the first power supply can stably supply power to the collection identification module.

It should be understood that, in the above embodiment, when the collection and identification module operates, a high level signal is sent to the control terminal of the third switching tube to control the detection module to stop operating. And when the acquisition identification module is disconnected with the power supply of the first power supply, a low level signal is sent to the control end of the third switching tube to control the detection module to start working. Because the energy consumption of the high-level signal is greater than that of the low-level signal, in the embodiment, when the acquisition and identification module stops working, the acquisition and identification module does not send the high-level signal any more, but sends the low-level signal instead, so that the detection module is controlled to start working, and the power consumption of the acquisition and identification module can be better reduced.
