The state of the current intelligent lock is obtained through the signal transmitting module and the signal receiving module, when the signal receiving module obtains a reflected signal, the reflected signal can be transmitted to the controller, and the controller controls the energy-saving circuit to cut off and disconnect so as to disconnect the active defense module, thereby saving energy, avoiding the problems of long-time power-on work and large electricity consumption of the active defense circuit, reducing the power consumption of the active defense function of the intelligent lock, reducing the power consumption of the intelligent lock, reducing the use frequency of a battery, and being more suitable for being used by a user conveniently. Specifically, the signal transmitting module of this embodiment is an infrared transmitting module, and the signal receiving module is an infrared receiving module, and the adoption of the infrared mode is more beneficial to energy saving. The controller is MCU. In this example, after the intelligent lock is opened to have an active defense function, the infrared emission module starts to intermittently emit infrared light to the outside, and the infrared light is reflected when being blocked; the infrared receiving module and the infrared transmitting module synchronously work in time sequence, and are mainly used for receiving the infrared light reflected by the transmitting module, converting the infrared light into identifiable signals and transmitting the identifiable signals to the controller; the energy-saving circuit is arranged in front of the active defense module, and the energy-saving circuit formed by the configurable transistors can be realized according to the on-off of the sequential logic control circuit because the active defense module is continuously started and consumes very much power.
As shown in fig. 3, the infrared receiving module includes a resistor R3, a resistor R4, a resistor R5, a capacitor C1, a capacitor C2, a capacitor C3, and an infrared receiver REC1, the capacitor C2, and the capacitor C3 are connected in parallel to two ends of the infrared receiver REC1, and the resistor R3, the resistor R4, and the resistor R5 are respectively connected in series to two ends of the infrared receiver REC 1.

As shown in fig. 3, the infrared emission module of this embodiment includes an infrared emission tube IR1, a resistor R6, a resistor R7, a resistor R8, and a triode Q2, wherein one end of the resistor R6 is connected to the emission control end, the other end of the resistor R6 is connected to the base of the triode Q2, the emitter of the triode Q2 is grounded, the infrared emission tube IR1 and the resistor R8 are connected in series to the collector of the triode Q2, and the resistor R7 is connected between the emitter and the base of the triode Q2 in parallel. The triode Q2 is used as a switching power supply, whether the whole circuit of the infrared emission module works or not is controlled through the on-off characteristic of the triode Q2, the infrared emission tube IR1 is used for emitting infrared rays, the resistor R8 is used for controlling the diameter range of infrared emission, and the specific circuit control method comprises the following steps: the INFRAREED IR port of the infrared emission module receives a level signal sent by the controller, when the signal is in a high level, the triode Q2 is conducted, the collector electrode of the triode Q2 outputs a low level, the infrared emission tube IR1 starts to work, otherwise, when the signal is in a low level, the triode Q2 is cut off, the collector electrode of the triode Q2 outputs a high level, and the infrared emission tube IR1 stops working.
As shown in fig. 2, the energy-saving circuit of the embodiment includes a resistor R1, a resistor R2 and a MOS transistor Q1, wherein the gate of the MOS transistor Q1 is connected to the controlled end of the energy-saving circuit through the resistor R2, the source of the MOS transistor Q1 is connected to a power supply, the drain of the MOS transistor Q1 is connected to the output end of the energy-saving circuit, and the resistor R2 is connected between the source and the gate of the MOS transistor Q1 in parallel. The MOS tube Q1 realizes energy saving by switching on and off according to a sequential logic control circuit, the MOS tube Q1 is a P-channel field effect tube, and the power consumption of the MOS tube Q1 is lower and more energy saving as the input impedance of the MOS tube Q1 approaches infinity, and the loss of the MOS tube Q1 is smaller. When the INFRAREED _POWER_CTRL port receives a level signal sent by the MCU controller, when the signal is in a high level, the MOS tube Q1 is cut off, the output of the INFRAREED _3.3V port is 0V, the active defense module does not work, otherwise, when the input signal is in a low level, the MOS tube Q1 is conducted, the output of the INFRAREED _3.3V port is 3.3V, and the active defense module works.
After the intelligent door lock is electrified, when a user starts an active defense function, the controller receives an opening signal and sends signals to the INFRAREED _POWER_CTRL port and the INFRAREED IR port, a program can be configured in the controller to realize the configuration of the number of times of sending the level in a period of time, the energy-saving circuit receives a low-level signal sent by the MCU, the MOS tube Q1 is conducted, and the active defense module is started. Meanwhile, the controller sends an instruction to a INFRAREED IR port, when an object and/or a human body is blocked within a set distance, the infrared transmitting tube IR1 is blocked and can reflect, a reflected signal is transmitted to an infrared receiver REC1 of the infrared receiving module, the infrared receiver REC1 converts the reflected signal into an electric signal and sends the electric signal to the controller through a INFRAREED _REC port, the controller compares the data with data sent to the INFRAREED IR1 port before, the data are the same, the energy-saving circuit receives a high-level signal when the data are blocked, the MOS tube Q1 is cut off, and the active defense module is closed to wait for the controller to enter the next cycle and then be started. Of course, a program can be configured in the controller, and the controller can judge that the shielding object is shielded only when the controller judges that the data are the same under the set times, namely, when the controller continuously receives signals within the set time range, the intelligent door lock starts to alarm and APP pushes alarm information to remind a user that someone stays outside the door so as to play a defending function. When no shielding object (object and/or human body shielding) exists in the set distance, the infrared transmitting tube IR1 may reflect due to the influence of medium in the outside air and the like and transmit signals to the infrared receiver REC1 of the infrared receiving module, the infrared receiver REC1 converts the signals into electric signals and transmits the electric signals to the controller through a INFRAREED _REC port, the controller compares the data with the data previously transmitted to the INFRAREED IR1 port, if the data are different, the data are judged to be non-shielding, the intelligent lock is in a safe state, the energy-saving circuit receives a high-level signal, the MOS tube Q1 is cut off, the active defending module is closed, the controller is waited to enter the next cycle and then open, and the intelligent door lock cannot alarm.
As shown in fig. 4, an energy saving method of an intelligent lock energy saving module includes:
transmitting a transmitting signal through a signal transmitting module;
if the signal receiving module receives the reflected signal, the energy-saving circuit is cut off to cut off the active defense module, so that energy saving is realized.

The controller outputs a transmitting signal control instruction to control the on-off of the signal transmitting module. The controller intermittently sends a transmission signal control instruction to the signal transmission module, so that energy conservation is further realized.
