[0045] Specifically, referring to Figure 7 , Figure 7The circuit diagram of the CPU main control module of the utility model is shown, the CPU main control module adopts MCU chip, the model is GD32F303CCT6, it has high-performance static CMOS technology, supports JTAG boundary scan, high-performance 32-bit CPU, supports peripheral interrupt extension (PIE) block of all 43 peripheral interrupts, 128-bit security key, enhanced control peripheral, serial port peripheral, 12-bit ADC, 16 channels, up to 35 multiplexed GPIO pins with input filtering function and can be edited individually, advanced simulation features, low power mode, energy saving.As shown in the figure, the MCU chip adopts 3.3v power supply, is provided with two crystal oscillator circuits, one is the crystal oscillator circuit composed of Y1 crystal oscillator, C1 capacitor, C2 capacitor and R1 resistor, is connected to the PD0-OSC_IN (pin 5) and PD0-OSC_OUT (pin 6) pins of MCU, and is used to provide low-frequency clock signal.The other is the crystal oscillator circuit composed of X1 crystal oscillator, C5 capacitor and C18 capacitor, is connected to the OSC32_IN (pin 3) and OSC32_OUT (pin 4) pins of MCU, and provides higher frequency clock signal.Pin 11-pin 13 are used for controlling LED circuit and are connected with LED_GREEN, LED_YELLOW and LED_RED respectively.Pin 25-pin 33 correspond to different key signal input information respectively.PWM_IR pin (pin 1) is used for receiving pulse width modulation signal from infrared receiving unit, and the MCU chip realizes infrared control function through processing the signal, and the USART2_TX (pin 21) and USART2_RX (pin 22) pins are used for being connected with electric actuator.

[0047] In some specific embodiments, the circuit of the LED indicating unit comprises three independent control driving circuits for controlling the on-off state of LEDs of three different colors (green, yellow and red) respectively. In each driving circuit, a corresponding LED lamp, a resistor and a transistor are equipped. Referring to Figure 9 , Figure 9 the circuit diagram of the LED indicating unit of the utility model is shown, as Figure 9 indicated, taking the green LED (LED_GREEN) as an example, the anode of the LED lamp D3 is connected with the 3.3V power supply through a resistor, while the cathode is connected to the ground through the transistor Q1. When the external control signal is applied to the transistor Q1 through TP9 and makes it conductive, the current will flow from the 3.3V power supply, through the resistor, the LED lamp D3 (LED_GREEN), and then through the collector to the emitter of the transistor Q1 to finally reach the ground, at this time, the LED_GREEN is lit. On the contrary, when the transistor Q1 is in the cut-off state, no current flows through the LED_GREEN in the circuit, thus causing the LED_GREEN to be extinguished. As for the driving circuits of the yellow LED (LED_YELLOW) and the red LED (LED_RED), the working principle is consistent with that of the green LED driving circuit, and the current path formation and blocking mechanism under the conductive and cut-off states of the transistor are followed to realize the on-off control of the LED lamps of different colors.

The circuit of transistor Q2 and resistance is used to control BL_EN signal, further controls the opening and closing of back light. When BL_EN signal is high level, (for example BL_EN=1), Q2 is turned on, and the back light is opened, when BL_EN signal is low level (for example BL_EN=0), Q2 is cut off, and the back light is closed. Specifically, transistor Q5 is WPM2015-3 / TR model, and the transistor is packaged as SOT23-3, and transistor Q2 is S8050 model, and the transistor is packaged as SOT23-3.

[0049] In practical applications, SPI interface or 8080 interface can be selected for communication with the display screen according to specific needs and system configuration.

The driving circuit inside the LCD display screen will control the deflection of the liquid crystal molecules according to the received data and control signals, so as to display the corresponding image or character on the screen. At the same time, through the circuit composed of transistors Q5 and Q2, the turning on and off of the backlight of the LCD display screen can be controlled to save power consumption or adjust the display effect according to the ambient light.
