[0058] Figure 1 This is a flow chart of a method for controlling a vehicle-mounted intelligent cup holder atmosphere light with a cooling function provided by an embodiment of the present application. Figure 1 , the method comprises the following steps:

[0059] 100. The bottom temperature of the vehicle-mounted intelligent cup holder is collected and processed by the temperature sensor module to obtain the current temperature value.

[0060] Optionally, the vehicle-mounted intelligent water cup holder atmosphere light system uses a temperature sensor module with an IIC interface to perform real-time collection and processing of the temperature at the bottom of the cup. Set up a memory with a first-in-first-out (FIFO) structure of length 5, which has the characteristic that the data that enters the memory first overflows first. When 5 temperature data are not collected, the temperature is displayed as 0. When 5 data are collected for the first time, the average value of the 5 temperature values ​​is calculated as the current temperature. Each subsequent temperature value is collected, the temperature value is placed in the FIFO entrance, and the data at the FIFO exit is removed, and the average value is calculated and displayed. The data collection cycle is set to 0.5 seconds. The temperature value calculation principle is as follows:

[0061] T(t) = 0;

[0062]

[0063] Among them, T i is the temperature value collected for the i-th time.

[0064] 200. The vehicle-mounted intelligent cup holder is temperature controlled according to the preset temperature and the current temperature value.

[0065] Optionally, the user can set the temperature through key input or Bluetooth APP. The system controls the OLED display screen through the SPI protocol to display the current temperature and set temperature value in real time. The system's cooling technology uses the Peltier effect, which describes the heat absorption or heat release phenomenon that occurs at the node when direct current passes through a loop composed of two different conductive materials. Through the heat absorption effect, the temperature at the joint will decrease and absorb external heat. The system's temperature regulation uses the PID algorithm, which is divided into the front-end control and PID regulation stages. Due to the large difference between the initial target water temperature and the actual water temperature, in order to speed up the adjustment of the water temperature, the PWM duty cycle is 100% for front-end control. The system works at full load. When the difference between the target water temperature and the actual water temperature is less than 5 degrees, it enters the PID regulation stage. The temperature control principle is as follows:

[0066] PWM0=100%,T(t)-T set >5;

[0067]

[0068] T(t)-Tset ≤5;

[0069] Among them, a0, b0 and c0 are proportional, integral and differential coefficients respectively, and the range is 0 to 1; (T set -T(t)) is the deviation between the target temperature and the current temperature value; the duty cycle of the voltage input to the semiconductor refrigeration chip is adjusted according to the temperature deviation.

[0070] 300. Receive an ambient light mode selected by a user through a user interface, and control the color, brightness, and display effect of the ambient light.

[0071] Optionally, the temperature of the liquid at the bottom of the cup is detected in real time through a temperature sensor, and the detected temperature is compared with the target temperature set by the user. The cooling intensity of the cooling module is adjusted according to the comparison result. At the same time, the color, brightness and display effect of the atmosphere light are controlled according to the two modes of the atmosphere light selected by the user through the user interface. Mode 1 of the atmosphere light is used to intuitively display the current temperature. The PWM duty cycle control principle of the three channels of the six RGB-RGB atmosphere lights is as follows:

[0072]

[0073] Among them, PWM1, PWM2, and PWM3 are red channel, green channel, and blue channel respectively. The brightness of the atmosphere light is proportional to the current temperature; a1, a2, and a3 are control coefficients, and their values ​​are all in the range of 0 to 0.5;

[0074] Mode 2 of the atmosphere light is used to rhythmically display the current temperature. The control principle of the three channels of the RGB-LED atmosphere light is as follows:

[0075]

[0076] Among them, PWM1, PWM2, and PWM3 are red channel, green channel, and blue channel respectively. The brightness and color of the atmosphere light are related to the temperature change value. The temperature is collected every 0.5 seconds. m1, m2, and m3 are the proportional coefficients of the three channels, and their values ​​are all in the range of 1 to 10. b1, b2, and b3 are control coefficients, and their values ​​are all in the range of 0 to 0.5.

[0077] Optionally, before collecting the bottom temperature of the vehicle-mounted intelligent cup holder through the temperature sensor module and processing it to obtain the current temperature value, the method further includes:

[0078] The 5V power supply is obtained by the DC-to-DC power conversion chip through the on-board 12V power supply; the 5V power supply is used to power the refrigeration drive circuit, and the 5V power supply is used to obtain a 3.3V power supply through a low-voltage difference linear regulator to power the microcontroller, Bluetooth module, OLED display, temperature sensor and ambient light drive circuit.

[0079] Based on the above examples, please refer to Figure 2 , an embodiment of the present application provides a vehicle-mounted intelligent cup holder atmosphere light control system with a cooling function, and the vehicle-mounted intelligent cup holder atmosphere light control system with a cooling function specifically includes: a microcontroller, a temperature sensor module, a power management module, a user interface, an OLED display screen, an atmosphere light driving circuit and an RGB-LED atmosphere light; the microcontroller is connected to the temperature sensor module, the power management module, the user interface, the OLED display screen, the atmosphere light driving circuit, and the atmosphere light driving circuit is connected to the RGB-LED atmosphere light.

[0080] Among them, the bottom temperature of the vehicle-mounted smart cup holder is collected and processed through the temperature sensor module to obtain the current temperature value; the temperature of the vehicle-mounted smart cup holder is controlled according to the preset temperature and the current temperature value; the ambient light mode selected by the user through the user interface is received, and the color, brightness and display effect of the ambient light are controlled.

[0081] In some embodiments, it also includes a refrigeration drive circuit, a semiconductor refrigeration sheet and a Bluetooth module; the microcontroller is connected to the refrigeration drive circuit, the semiconductor refrigeration sheet and the Bluetooth module; the user interface is provided with a temperature control button and an atmosphere light mode selection button.

[0082] In some embodiments, please refer to Figure 3 The cup holder structure of the vehicle-mounted intelligent cup holder is cylindrical; the outer side of the cup holder of the vehicle-mounted intelligent cup holder is composed of the RGB-LED atmosphere light and a translucent shell, and the inside of the shell contains 6 RGB-LED atmosphere lights; the temperature sensor module and the semiconductor refrigeration sheet are arranged at the bottom of the cup holder.

[0083] In some embodiments, the power supply of the system is provided by a 12V power supply on the vehicle, and the 12V power supply is converted into 5V and 3.3V power supplies by a power management module. The structure of the power management module is as follows: Figure 4 As shown. Among them, 5V is used to power the cooling drive circuit, and 3.3V is used to power the MCU, Bluetooth module, OLED module, temperature sensor, and atmosphere light drive circuit. The circuit system structure of the smart cup holder atmosphere light is shown as follows: Figure 1As shown in the figure, it consists of a microcontroller, a Bluetooth module, a temperature control button, a refrigeration drive circuit, a semiconductor refrigeration chip, an atmosphere light drive circuit, 6 RGB-LED atmosphere lights, a power management module, a temperature sensor and an OLED display. The semiconductor refrigeration chip is installed at the bottom of the smart water cup holder, as shown in the figure. Figure 3 As shown in . At the same time, the control circuit part is also installed at the bottom of the cup holder, and 6 RGB-LED lights are installed around the side of the cup holder.

[0084] Among them, the purpose of the power management module is to generate 5V and 3.3V power supplies, and a DC-DC chip is used to convert a 12V power supply into a 5V power supply, which has the advantage of low power consumption. A DC-DC (model TPS5430) and an LDO (model XC6206) are connected in series to generate a 3.3V power supply, which has lower power ripple.

[0085] In some embodiments, the temperature is set by key input or Bluetooth APP, where the key control part includes 2 independent keys, namely GPIO1 and GPIO2. When the GPIO1 key is pressed, the preset temperature increases by 0.1 degrees Celsius, and when the GPIO2 key is pressed, the preset temperature decreases by 0.1 degrees Celsius. When no key is pressed within 3 seconds, the MCU sets the temperature value at this time to the preset temperature. The Bluetooth APP connects to the MCU through the Bluetooth protocol, and can set the temperature with a resolution of 0.1 degrees Celsius, and can control the display mode of the atmosphere light.

[0086] Exemplarily, when the system is turned on, the program is first initialized, the IIC, SPI, GPIO, serial port, and PWM peripherals that need to be run are enabled and the initial parameters are configured, and then the OLED display is controlled to display the previously preset temperature value. When the user configures the system through buttons or Bluetooth, including setting the temperature and the atmosphere light mode, the system performs cooling and controls the atmosphere light to display different effects in real time. Specifically, the current water temperature is measured by the temperature sensor module, compared with the target water temperature, and the working mode is controlled. The OLED display displays the temperature and the system starts to control the temperature adjustment to detect whether the target water temperature is reached. If the target water temperature is reached, the system controls to enter the insulation mode and issues a notification. If the target water temperature is not reached, the system drives the temperature adjustment.

[0087] Among them, the refrigeration drive circuit is as follows Figure 5As shown in the figure, it consists of an NPN transistor, a current limiting resistor and a semiconductor refrigeration film. The PWM1 signal is a periodic rectangular wave, in which the low level amplitude is 0V and the high level amplitude is 3.3V. Its duty cycle can be adjusted by the MCU. When the PWM1 signal outputs a high level, the transistor is turned on, and the current flows from the power supply through the current limiting resistor to the refrigeration film, so that the refrigeration film performs cooling work. When the PWM1 signal outputs a low level, the transistor is turned off, and the refrigeration film stops working. By setting the duty cycle of the PWM1 signal, the on-time and off-time ratio of the semiconductor refrigeration film can be set, thereby controlling the refrigeration power of the refrigeration film.

[0088] In some embodiments, the atmosphere light has two display modes, namely, an intuitive display of the current temperature mode and a rhythmic display of the current temperature mode. In the intuitive display of the current temperature mode, the brightness and color of the atmosphere light change with the current real-time temperature value. In the rhythmic display of the current temperature mode, the brightness and color of the atmosphere light change with the temperature change rate.
