[0031] In order to make the technical solutions and technical effects of the patent more clear, the specific implementation of the patent will be described in detail below in combination with the drawings and embodiments.

[0032] Embodiment one:

[0033] As Figure 1 , the intelligent magic mirror in the embodiment includes a power conversion module, a clock module, a music module, a lighting module, a cabinet door lifting and anti-pinch module, a temperature detection module, a defogging module, a gray scale control module, a communication module, a display module and an MCU.

[0034] The power conversion module is used to convert the higher voltage DC power into lower voltage DC power. Its input end is connected to the external power adapter, and its output end is connected to the power pins of each module. Figure 2 The module uses a DC-DC power supply chip model TPS5430DDAR, inputs a 12V DC power supply, and outputs VCC (5V).

[0035] The clock module is used to generate clock signals, and its output is connected to the MCU. Figure 3 The module uses the clock chip HT1381 to generate the clock signal of year, month, day, hour, minute and second to the MCU. After receiving the clock signal, the MCU outputs it to the display module for display.

[0036] The music module is used to generate music of different frequencies and beats, and its input end is connected to the MCU. Figure 4 The module includes PNP transistor Q1, NPN transistors Q2 and Q3, buzzer BUZ1, current limiting resistors R2, R4, R9, pull-up resistors R1 and R8, resistor R5, resistor R6, capacitors C3 and C6, and decoupling capacitor EC2. Resistor R4 is connected to the MCU's BUZH pin and the base of Q2. Q2's collector is connected to one end of R1, the other end of R1 is connected to a 12V power supply, and Q2's emitter is grounded. C2 is connected in parallel between Q2's base and emitter. R2 is connected to Q2's collector and the base of Q1. Q1's emitter is connected to the 12V power supply, and its collector is connected to one end of R6. The other end of R6 is connected to one end of R8. BUZ1 is connected in parallel across R6. The other end of R8 is connected to Q3's collector. Q3's base is connected to one end of R9, and the other end of R9 is connected to the MCU's BUZF pin. Q3's emitter is grounded. C6 is connected in parallel between Q3's base and emitter. R5 is connected to Q1's collector and one end to the positive terminal of EC2. EC2's negative terminal is grounded. The MCU's BUZF pin outputs a pulse train signal. By controlling the frequency of this signal, the tone of the BUZF buzzer is controlled. The BUZH pin outputs a PWM signal. By controlling the PWM signal's duty cycle, the duration of the buzzer BUZ1's sound is controlled. When BUZH is high, Q1 and Q2 are both on. When the BUZF pulse signal is high, Q3 is on, and BUZ1 sounds. When the BUZF pulse signal is low, BUZ1 is silent. Because the BUZF signal's frequency is within the audible range of the human ear, the BUZH signal has a lower frequency, allowing for simultaneous control of both the frequency and duration (music tempo) of the sound emitted by BUZ1. When BUZH is low, Q1 and Q2 are both off. The energy stored in EC2 during the BUZH high period flows through BUZ1, producing a tail tone and smoothing the sound.

[0037] The lighting module is used to generate rhythm and color alternating light, and its input end is connected with the MCU. Figure 5 The lighting module includes red light circuit, blue light circuit and purple light circuit. LED1, LED2, LED3 and LED4 are four common anode red-violet-blue combined light emitting diodes. The connection and working principle of the circuit are described by taking the blue light circuit as an example. The base of NPN triode Q5 is connected with the BULE pin of the MCU after connecting with current-limiting resistor R36 in series, the emitter is connected with the ground, and the resistor R38 is connected in parallel between the emitter and the base. The collector is connected with four parallel blue light diode circuits. The first blue light diode circuit includes resistor R29 and the blue light emitting diode in LED3, one end of R29 is connected with the collector of Q5, one end of R29 is connected with the negative electrode of the blue light emitting diode, and the positive electrode of the blue light emitting diode is connected with the DC power supply VCC. When the BLUE pin outputs high level to the base of Q5, Q5 is turned on, the emitter of Q5 is low, the blue light emitting diode in LED3 is turned on to emit blue light, and the blue light emitting diodes in LED1, LED2 and LED4 are turned on at the same time to emit blue light. When the BLUE pin outputs low level to the base of Q5, Q5 is turned off, and the blue light emitting diodes in LED1, LED2, LED3 and LED4 do not emit light. The working principles of other color light emitting diodes are the same, and are not described here. The MCU controls the output of the BULE, RED and PURPLE pins to output high and low level in sequence and for a certain duration, so as to generate rhythm and color alternating light.

[0038] The cabinet door lifting and anti-pinch module opens and closes the cabinet door of the dressing table according to the user's instruction, and detects whether the hand is near the cabinet door when the cabinet door is closed. The cabinet door lifting input end is connected with the MCU, and the anti-pinch output end is connected with the MCU. The cabinet door lifting and anti-pinch module includes cabinet door lifting circuit and anti-pinch circuit. Figure 6The cabinet door lifting circuit comprises a chip XC3066, a direct current brushless motor (not shown), resistors R13, capacitors C16, C17, C18, an electrolytic capacitor EC4 and an inductor N2. Two input terminals of the XC3066 are connected to IN1 and IN2 pins of the MCU, a power supply terminal VREF is connected to a direct current power supply terminal VCC, output terminals OUT1 and OUT2 are connected in parallel between primary input terminals of the inductor L2, and secondary output terminals are connected in parallel between positive and negative terminals of the direct current brushless motor. The direct current brushless motor is installed on the cabinet door. The anti-pinch circuit comprises a capacitive touch sensing strip and a resistor R10. The capacitive touch sensing strip and the resistor R10 are connected in series. The capacitive touch sensing strip is installed on a side surface of the cabinet door, and an output terminal thereof is connected to a TKEY1 pin of the MCU. When a user inputs an instruction to open the cabinet door, the MCU controls output voltage difference between IN1 and IN2 to be +5V, output voltage difference between OUT1 and OUT2 to be +12V, and the motor rotates in a forward direction to open the cabinet door. When the user inputs an instruction to close the cabinet door, the MCU controls output voltage difference between IN1 and IN2 to be -5V, output voltage difference between OUT1 and OUT2 to be -12V, and the motor rotates in a reverse direction to close the cabinet door. At the same time when the cabinet door is closed, if the capacitive touch sensing strip senses a hand near the cabinet door, an output detection signal is output. Specifically, the TKEY1 outputs a capacitive value signal of human touch or approach or distance to the MCU. When a hand of a person touches or approaches the cabinet door, the MCU controls output voltage difference between IN1 and IN2 to be 0V, and the motor stops rotating to prevent the cabinet door from pinching the hand.

[0039] The temperature detection module is used for detecting an ambient temperature, and an output terminal thereof is connected to the MCU. As shown in Figure 7 One end of a series circuit of the thermistor PTC1 and the resistor R41 is connected to the power supply VCC, and the other end is connected to the ground. One end of the resistor R39 is connected between the PTC1 and the R41, and the other end is connected to an RT pin of the MCU. When the ambient temperature changes, the resistance of the thermistor PTC1 changes, and the voltage on the R41 changes. The MCU can calculate the ambient temperature according to the detected voltage on the R41, and send the ambient temperature to the display module for display through the communication module.

[0040] The defogging module is used for eliminating water mist on the mirror surface of the intelligent magic mirror, and an input terminal thereof is connected to the MCU. As shown in Figure 8 The defogging module comprises an N-channel MOS tube Q9, a current-limiting resistor R47, a resistor R49, a socket P5 and a diode D4. The socket P5 is connected to a heating element (not shown), the P5 and the D4 are connected in parallel, the negative electrode of the D4 is connected to a 12V power supply, the positive electrode is connected to the drain electrode of the Q9, the source electrode is connected to the ground, the gate electrode is connected to an H0T pin of the MCU through the resistor R47 in series, and the R49 is connected in parallel between the gate electrode and the source electrode of the Q9. When the H0T outputs a high level, the Q9 is turned on, the heating element connected to the socket P5 is heated to eliminate the water mist on the mirror surface, and when the H0T outputs a low level, the Q9 is turned off, and the heating element is not heated.

[0041] A gray scale control module is used to control the gray scale of the lighting module, and an input end of the gray scale control module is connected to the MCU. Figure 8 The light gray scale control module circuit and the defogging module circuit have the same structure, and thus will not be described here again. The lamp strip is connected to the sockets P4 and P6. The MCU controls the LED1 and LED2 pin outputs PWM signals according to the gray scale parameters of the lighting module input by the user. When the duty cycles of the PWM signals are different, the conduction times of Q6 and Q8 are different, the currents flowing through the lamp strip module connected to P4 and P6 are different, and the brightness displayed by the lamp strip is also different, thereby achieving the purpose of adjusting the gray scale of the lighting module.

[0042] A display module is used to accept user instructions and display information from the MCU, and is connected to the communication module. The display module in the embodiment is purchased, and is a display screen with a knob or touch key, or a voice recognition circuit. The user inputs on / off smart magic mirror light, opens / closes defogging, opens / closes voice, adjusts the gray scale, and the like through the knob or touch key, or voice. The instructions are sent to the MCU through the communication module, the MCU analyzes the instructions, and controls the work of the corresponding module.

[0043] A communication module is used for data exchange between the display module and the MCU on the magic mirror, one end of the communication module is connected to the MCU, and the other end is connected to the display screen through a connection line (not shown). Figure 9 The communication module includes a display communication circuit and a voice communication circuit, and the working principles of the two communication circuits are the same. The circuit connection and working principle of the display communication circuit will be described as an example. One end of the connection line is connected to the display screen, and the other end is connected to the socket P2. The resistors R17 and R24 are current limiting resistors. One end of the resistor is connected to the socket P2, and the other end is connected to the sending or receiving pin of the MCU. In this embodiment, the MCU adopts the 485 communication mode.

[0044] The MCU controls the work of each module according to the collected data and user instructions. In this embodiment, a chip with the model number SC95R503P32R is adopted.
