The SDA interface of the temperature and humidity sensor U3 is connected to the 12C SCL line, the ADDR interface, EPAD interface, VSS interface, and R interface of the temperature and humidity sensor U3 are all grounded to GND, the ALERT interface of the temperature and humidity sensor U3 is left unconnected, the SCL interface of the temperature and humidity sensor U3 is connected to the 12C SDA line, the VDD interface of the temperature and humidity sensor U3 is connected to the power supply VCCIO, and a resistor R11 is provided between the NRESET interface and the VDD interface of the temperature and humidity sensor U3. The 12C bus has two bidirectional signal lines, one data line SDA for sending and receiving data, and one clock line SCL for synchronizing the clocks of both communication parties.

[0057] The following specifically describes Figure 2 the meanings of the respective interfaces or pins in

[0058] The SDA interface (Serial Data Line) is a bidirectional data transmission line in the I2C communication protocol. In the circuit design of the SHT35-DIS-B temperature and humidity sensor, this interface is responsible for data exchange between the master and slave devices. Through the SDA line, the sensor can send temperature and humidity measurement data and also receive configuration instructions from the master controller.

[0059] The SCL interface (Serial Clock Line) is the clock synchronization line of the I2C communication protocol. Its function is to provide a communication clock signal to ensure the synchronization and accuracy of data transmission. During the communication process of the temperature and humidity sensor, the SCL line coordinates the rhythm of data transmission, enabling the sender and receiver to work precisely in coordination and preventing data transmission chaos.

[0060] The ADDR interface (Address) is used for device address selection and is directly grounded (GND) in this circuit.

[0063] The R interface is the reference voltage or pull-up resistor interface and is grounded in this circuit. The pull-up resistor is used in I2C communication to maintain the logic level of the bus, ensuring that the bus is in a definite logic state when there is no effective communication.

[0064] The ALERT interface is the alarm interface or interrupt output interface and is left unconnected in this circuit. This interface is used to actively send an interrupt signal to the master controller when the sensor detects an abnormal situation (such as exceeding the threshold), reminding the system to perform corresponding processing.

[0065] The VDD interface (Voltage Drain / Drain Voltage, power supply pin), which is the positive power supply input and is connected to the VCCIO power supply in this circuit. It provides the power required for the sensor to operate, with a voltage of around 3.3V or 5V. A stable power supply is crucial for the accurate measurement and reliable operation of the sensor.

[0066] The NRESET interface (Negative Reset, negative reset interface or negative level reset), which is the reset pin and has a resistor R11 connected between it and VDD in this circuit. The reset interface allows the chip to return to a known initial state either through hardware or software means, clearing possible abnormal operating states and is an important design for ensuring system stability.

[0072] The following is a specific description Figure 3 of the meanings of each interface or pin:

[0073] The GND interface of USBC1 is the grounding point in the circuit, providing the reference potential for the circuit system. In a USB connector, the GND interface ensures electrical safety and signal stability between devices, preventing electrostatic and electromagnetic interference. It is an essential basic interface in the USB communication and power supply system.

[0074] The DP2 interface of USBC1, that is, DP2 (Data Positive 2), is the positive data line of the USB connector, used for differential signal transmission in USB communication. In this circuit, the DP2 interface is connected to the I / O1 first interface of the protection diode U1, playing a dual role in signal transmission and electromagnetic protection. It is a key channel for high - speed USB data transmission.

[0075] The DN2 interface of USBC1, that is, DN2 (Data Negative 2), is the negative data line of the USB connector, also used for differential signal transmission in USB communication. In this circuit design, the DN2 interface is connected to the I / O2 first interface of the protection diode U1, jointly forming a complete channel for USB data transmission with DP2 to ensure data accuracy and anti - interference ability.

[0076] DP1, which is the differential positive signal (Data Positive 1), is the positive signal line used for data transmission. It is one of the lines in USB signal transmission and carries the positive level of the data.

[0077] DN1, which is the differential negative signal (Data Negative 1), is the negative signal line used for data transmission. It forms a differential signal pair with the DP1 line in USB data transmission, providing higher anti-interference ability and more stable data transmission.

[0078] The GND interface of U1 is the ground point of the internal circuit. Grounding can stabilize the operation of the device, reduce electrical noise, protect the USB interface from electrostatic and transient overvoltage, and is the basis for the normal operation of the protection diode.

[0079] The I / O1 and I / O2 interfaces of U1 are the input interface / output interface of the protection diode. In this circuit, I / O1 and I / O2 are respectively connected to the data line of the USB connector and the USB to serial chip, playing the role of signal transmission and electromagnetic protection, and can effectively suppress transient overvoltage and electrostatic discharge.

[0080] The Vbus interface of U1 is the USB power supply interface, which is directly connected to the power supply VCC in this circuit.

[0085] USBDP (USB Data Positive, the positive USB data line) and USBDM (USB Data Negative, the negative USB data line) are the two data lines for USB differential signal transmission. These two interfaces together constitute the physical layer transmission channel for USB communication. Using the differential signal transmission mode can effectively suppress electromagnetic interference and improve signal noise immunity. USBDP represents the positive data line, and USBDM represents the negative data line. They transmit data through voltage changes that are opposite to each other. When the voltage on one line rises, the voltage on the other line drops accordingly. This differential signal transmission method can not only improve the reliability of data transmission but also reduce electromagnetic radiation. In practical applications, USBDP and USBDM need to be used in combination to jointly complete the accurate transmission of data.

In some specific applications, PB1 is used as a timer, external interrupt signal, or other special functions. It is used to interact with external devices and supports multiple peripherals and communication interfaces.

[0104] BOOT0 is the boot configuration pin of the STM32 microcontroller. By controlling the level (high or low) of BOOT0, the microcontroller can determine where to start the program. When BOOT0 is high, the microcontroller will start from the system bootloader, and when BOOT0 is low, it will start the program from the flash memory or external memory. This pin is used to select the startup mode of the microcontroller and is used together with the external circuit for boot mode selection.

[0105] NRST is the reset pin of the STM32 microcontroller. It is used to reset the microcontroller to its initial state and restart. During reset, all the registers and peripherals inside the microcontroller will be initialized, and the system enters the initial state.

The VDD voltage is 3.3V or 5V, depending on the model of the microcontroller used. This pin supplies power to the internal circuit and I / O interface of the microcontroller to ensure that all modules of the device (such as the CPU, memory, peripherals) work properly. VDD needs to be powered by an external power supply and is connected to the positive pole in the circuit.

[0108] VDDA is the analog power supply voltage pin of the STM32 microcontroller, which is used to provide a stable power supply for the analog part of the microcontroller. Different from VDD, VDDA powers the analog part in the microcontroller, such as analog input, digital-to-analog conversion (DAC), analog-to-digital conversion (ADC), etc.

[0109] txd (Transmit Data), which is used to send data to external devices in serial communication. It is used to transfer data from a slave device to a master device. During data communication, txd is used to send the data to be transmitted, ensuring that the data can be smoothly transferred from one device to another. This pin is unidirectional and mainly used for outputting data.

[0110] rxd (Receive Data), which is used to receive data sent from an external device (master device). In the serial communication protocol, rxd is used to receive data from the master device and input it into the processing unit of the slave device. Working in conjunction with the txd pin, rxd is the channel for inputting data, ensuring that the slave device can obtain instructions or data from the master device.

[0111] SWDIO (Serial Wire Debug Input / Output) is part of the serial debug interface, allowing developers to interact with the STM32 microcontroller through the debug communication protocol. Through this pin, developers can perform program debugging, troubleshooting, and real-time monitoring of the code. The SWDIO pin supports bidirectional data transmission and is used to exchange data and commands during the debugging process.

[0112] SWCLK (Serial Wire Debug Clock) is the clock signal line in the serial debug protocol, used to synchronize the transmission of debug data. It works together with the SWDIO pin to provide clock pulses for the debugging process, ensuring the correct timing of data transmission.

[0113] VCCIO is the power supply voltage input pin, used to provide a voltage of 3.3V for the I / O interface of the STM32 microcontroller. It provides power support for the digital circuits of all I / O pins, enabling these pins to work properly and output digital signals.

[0114] Specifically, as Figure 5 shown, in the circuit diagram of the gateway 3, Ln1134A332MR-G is the low dropout linear regulator LDO1. The VIN interface of the LDO1 is grounded through the capacitor C6. The VIN interface of the LDO1 is connected to the CE interface of the LDO1. The VSS interface of the LDO1 is grounded. The VOUT interface of the LDO1 is grounded through the capacitor C5. The VOUT interface of the LDO1 is connected to the power supply VCCIO. The capacitor C5 is in parallel with the capacitor C9. The power supply VCCIO is between the capacitor C5 and the capacitor C9.

[0115] Specifically, as Figure 6As shown, when the sensor module 2 acquires data, it should measure at multiple points, and then obtain the environmental data based on the multi-point measurement values. The position where the sensor module 2 is located is the measurement point. The distance between the measurement point and the mattress in the infant incubator 1 is preferably 10 cm. The sensor module 2 is fixed in the infant incubator 1 through a bracket. Figure 6 Among them, point A is the measurement point for the central temperature of the infant incubator, and points B, C, D, and E are other temperature measurement points. Point A can also be the measurement point for humidity.

[0116] Embodiment 2

[0117] As Figure 7 shown, the distributed infant incubator calibration method includes the following steps:

[0118] S10: Obtain the ID code and environmental data from the infant incubator 1;

[0119] S20: Generate an association relationship according to the ID code;

[0120] S30: Generate a calibration instruction according to the environmental data;

[0121] S40: Send the calibration instruction to the infant incubator 1 according to the association relationship.

[0122] Specifically, in step S10, the ID code and environmental data are obtained through the sensor module 2. The sensor module 2 needs to be disinfected before entering the infant incubator 1 to avoid harmful bacteria on the sensor module 2 from coming into contact with the baby.

[0123] Specifically, step S10 includes the following steps:

[0124] S11: Obtain the ID code from the infant incubator 1;

[0125] S12: Obtain several initial environmental data at different positions in the infant incubator 1;

[0126] S13: Calculate the environmental data based on several pieces of the initial environmental data.

[0127] Specifically, the ID code can be in the form of a two-dimensional code, a bar code, or a digital code. The ID code is recognized through a preset recognition database, so as to accurately issue a calibration instruction in subsequent steps. The several initial environmental data are obtained through various sensors, and various sensors are integrated in the sensor module 2. The types of the sensors include but are not limited to a temperature sensor, a humidity sensor, an oxygen concentration sensor, or a flow rate sensor, etc. In step S13, the several initial environmental data are classified according to the sensor type, such as temperature sensor data and humidity sensor data, etc., and then the average value of each type of initial environmental data is calculated, and the several obtained average values are used as environmental data.

[0128] Specifically, step S30 includes the following steps:

[0129] S31: Preprocess the environmental data to obtain data to be grouped;

[0130] S32: Group the data to be grouped according to the sensor type to obtain several groups of data;

[0131] S33: Obtain several preset sensor type thresholds, and generate several types of initial regulation instructions according to the several sensor type thresholds and the several groups of data;

[0132] S34: Generate a regulation instruction according to the several types of initial regulation instructions and send it to the infant incubator 1.

[0133] Specifically, in step S31, the preprocessing includes denoising, data cleaning, and outlier identification and correction, etc. The sensor type thresholds are set according to the user manual of the infant incubator 1.

[0134] Specifically, specifically, step S33 includes the following steps:

[0135] S331: Obtain several preset sensor type thresholds;

[0136] S332: Calculate the deviation value of each group of data according to the several sensor type thresholds and the several groups of data;

[0137] S333: Obtain several preset deviation ranges, each deviation value corresponds to one deviation range. When there is a deviation value that does not belong to the deviation range, an alarm is issued. When each deviation value belongs to the corresponding deviation range, go to step S334:

[0138] S334: Generate several types of initial regulation instructions according to the several sensor type thresholds and the several groups of data.

[0139] Specifically, the deviation value is the difference between the sensor type threshold and the data corresponding to the sensor. When the deviation value is too large, regulation is required. For example, the temperature fluctuation does not exceed ±1.0 °C, and the humidity error does not exceed ±10% RH.

[0140] Specifically, it further includes step S50: obtaining the calibration environment data in the infant incubator (1) calibrated according to the calibration instruction, determining whether the calibration is successful according to the calibration environment data and a preset calibration range, and if the determination is unsuccessful, issuing a fault alarm.

[0141] S51: obtaining the calibration environment data in the infant incubator 1 calibrated according to the calibration instruction;

[0142] S52: grouping the calibration environment data according to the sensor type to obtain several groups of calibration data;

[0143] S53: obtaining several groups of preset calibration ranges, each group of the calibration data corresponding to one of the calibration ranges. When there is calibration data that does not belong to the calibration range, a fault alarm is issued. When each group of the calibration data belongs to the corresponding calibration range, it indicates that the calibration is successful.

[0144] Specifically, the step S50 is used to determine whether the calibration instruction is effectively executed. If, after a period of time since the calibration instruction is issued, the calibration range is still not satisfied, it indicates that there is a device failure in the system, resulting in the inability to accurately control the infant incubator 1. At this time, an alarm is issued to call the staff for maintenance.
