Specifically, as shown in fig. 2, power is supplied to the light control circuit through the power adapter. The control module 20 implements the following functions:
ADC temperature acquisition: the temperature information is acquired by acquiring the voltage value of the adjustable resistor (R17) through the adjustable resistor (R17) by the internal ADC temperature sensor of the third main control chip (U3), preferably, the temperature information is sent to the wireless communication module 10 through the serial port every 10 seconds, and is sent to the mobile terminal 1 by the wireless communication module 10, so that the mobile terminal 1 can periodically display the temperature information.
And (3) power supply output control: the human-computer interaction module 30 obtains the operation information input by the user and analyzes the operation information to obtain a corresponding control signal, and the wireless communication module 10 receives the operation information of the mobile terminal 1 and analyzes the operation information to obtain a corresponding control signal. In the operation process, the control signal from the human-computer interaction module 30 and/or the wireless communication module 10 is received, and the voltage duty ratio of the output power supply is adjusted according to the control signal, so that the on-off of the lamp 3 and the brightness value adjustment of the lamp 3 are realized at any time according to the change of the voltage duty ratio.
For example, when the lamp 3 is switched to the off state, the duty ratio is not changed suddenly, but is changed gradually at a preset period (for example, 20ms) to achieve smooth change of the light without flickering. For example, if the duty ratio corresponding to the brightness value in the lighting state of the lamp 3 is 70%, the lamp 3 is controlled to decrease the duty ratio value every 20ms according to the duty ratio difference value of 10%, that is, the lamp 3 is decreased from 70% to 60% after the first 20ms, then the lamp 3 is decreased from 60% to 50% after the second 20ms, and so on until the duty ratio reaches 0, the lamp 3 is switched to the off state. Similarly, when the lamp 3 is switched to the lighting state, the duty ratio is not changed suddenly, but is changed gradually at a preset period (for example, 20ms), so as to implement the smooth change of the lamp light without flickering. For example, the duty ratio corresponding to the off state of the lamp 3 is 0, and assuming that the duty ratio corresponding to the on state of the preset lamp 3 is 5%, the lamp 3 is controlled to increase the duty ratio value every 20ms according to the duty ratio difference value of 1%, that is, the lamp 3 is increased from 0 to 1% after the first 20ms, then the lamp 3 is increased from 1% to 2% after the second 20ms, and so on until the duty ratio reaches 5%.
The light brightness state memory function: the brightness value of the lamp light is 0x 00-0 x64, i.e. the brightness of the lamp 3 can be set to 0% -%. The third processing unit compares the light brightness value every 2 seconds, and when the change difference exceeds 5, the third processing unit writes the light brightness value into the designated position of the internal FLASH. When the system is powered on again, the third processing unit is used for lighting by reading the value stored in the position as a light brightness value.
The PWM breathing special effect is as follows: the breathing lamp effect is realized through PWM control, and 90 points sampled by one breathing curve period are stored in a PWM list, so that the brightness of the lamp 3 is changed gradually in the bright and dark.
In the above embodiment, the wireless communication module 10, the human-computer interaction module 30 and the control module 20 respectively perform cascade communication through the first communication connector unit, the second communication connection unit and the third communication connection unit. As shown in fig. 2, the human-computer interaction module 30, the control module 20, and the wireless communication module 10 communicate through UART cascade, and control signals of the UART cascade all conform to a structure format of a system instruction data packet, where the structure format is shown in table 1:

4. AUTO: on/off unattended mode
Controlling light: the mobile terminal 1 can control the on and off of foreground light, the intensity control of light brightness, and the on and off of a light breathing special effect (the breathing time can be adjusted). For example, the user may set the brightness of the lamp light to 31% or 81% as desired.
Unattended mode: in the following step 9: 00 to 18: 00, the light is automatically turned on within the preset working time period, and is automatically turned off when the preset working time period is exceeded, and the mode can be controlled to be turned on or off by a mechanical key or a touch key at the mobile terminal 1 and the human-computer interaction module 30.
Clock calibration: when the mobile terminal 1 is connected to the light control system corresponding to the intelligent foreground, the time of the mobile terminal 1 can be manually synchronized to the light control system of the intelligent foreground, and the accuracy is up to the second.
Temperature monitoring: the light control system of the intelligent foreground sends the real-time temperature information collected by the control module 20 to the mobile terminal 1 to monitor whether the temperature is normal.
