[0038] The sensor peripheral circuit 5 is used to measure the flight altitude of the UAV and obtain the attitude information of the UAV to ensure stable flight of the UAV in complex environments.

[0039] In this implementation, the main control module 1 provides precise control through an STM32F4 chip and converts 5V to 3.3V through an LDO regulator to ensure stable system operation. The communication circuit 2 is responsible for data transmission between UAVs and enables Wi-Fi communication between the UAV and the ground control system. The power supply circuit 3 controls the LED lights and motors to achieve flight control of the UAV. The sensor peripheral circuit 5 ensures stable flight of the UAV in complex environments. This integrated circuit system has a highly integrated structure and comprehensive functions, designed specifically for emergency rescue scenarios. Combining multiple functional modules, it realizes an efficient, stable, and easy-to-operate UAV system that can provide critical real-time data to support rescue decisions. It also has advantages such as low power consumption, high stability, and scalability, enabling it to operate efficiently in different rescue environments.

[0040] Furthermore, the main control module 1 includes a power management unit, a clock circuit, a reset circuit, and a debugging interface.

[0041] In this implementation, the power management unit converts the external 5V voltage to 3.3V via an LDO (low-dropout linear regulator), providing stable power support for the STM32F4 main control chip and other external devices, ensuring stable system operation under low power consumption. The clock circuit provides an 8MHz main clock signal to the system via an external crystal oscillator. The 32.768kHz crystal oscillator is used for the RTC (Real-Time Clock) function during low power consumption. All peripherals and the CPU operate based on this clock signal, similar to the system's "heartbeat," providing a foundation for precise system control. The reset circuit is implemented using a hardware button and the chip's NRST pin. Pressing the reset button debouncing via a capacitor ensures a stable and reliable reset process. This function is primarily used for manual restart in case of system failure. The debugging interface, via the SWD debugging interface (including SWDIO and SWCLK signals), enables online debugging and firmware burning of the STM32F4 chip, facilitating system development and debugging.

[0042] Furthermore, the communication circuit 2 includes an NRF2401 module and an ESP8266 module, wherein the ESP8266 module includes an external drive circuit 4 and a basic operating circuit.

[0043] In this embodiment, the communication circuit 2 mainly consists of the NRF2401 module and the ESP8266 module, which work together to achieve efficient data transmission. The NRF2401 module, based on the NRF2401 chip, is primarily used for wireless data transmission and reception between UAVs, such as... Figure 2As shown. The NRF2401 is a low-power, high-performance wireless transceiver chip widely used in short-range wireless communication systems. The core component of this wireless communication circuit is the NRF2401 chip, whose power supply pins are connected to the power supply circuit to provide a stable voltage. The power supply circuit includes a voltage regulator and a filter circuit to ensure the normal operation of the NRF2401. The data interface circuit is connected to the microcontroller via GPIO pins to achieve bidirectional data transmission, while the control pins are used to configure the operating mode of the NRF2401. Wireless signal transmission and reception rely on the antenna, which is connected to the antenna pin of the NRF2401. To ensure accurate data transmission and reception, a crystal oscillator circuit provides a precise clock signal to the NRF2401; the crystal oscillator connected to the clock pin is typically 16MHz. Resistors and capacitors in the peripheral circuit are used for circuit stability and filtering. During operation, the microcontroller sends data to the NRF2401 through the data interface circuit; the NRF2401 modulates the data into a wireless signal and transmits it through the antenna. During reception, the antenna receives the wireless signal, the NRF2401 demodulates the signal, and transmits the raw data back to the microcontroller through the data interface circuit. The NRF2401 supports various communication parameter configurations, such as communication frequency and baud rate, which can be flexibly set through microcontroller programming.

[0044] The ESP8266 module mainly consists of two parts: the external drive circuit 4 and the basic operating circuit. It is used for Wi-Fi communication to realize data transmission between the ground control station and the UAV. The basic operating circuit is as follows: Figure 3 As shown. The module is powered by a 3.3V power supply, combined with a filter design using resistors and capacitors to ensure a clean and stable power supply for the ESP8266, thereby guaranteeing communication reliability. The ESP8266 module is the core of this circuit, responsible for Wi-Fi connectivity, data transmission, and control logic. It has TXD and RXD pins for data transmission, an RST pin for reset, and an ADC pin for analog signal input. The reset circuit uses a combination of button KEY2 and capacitor C10. When KEY2 is pressed, a reset signal is triggered, ensuring the module can quickly recover in abnormal situations. Through a combination of button KEY1 and a resistor, users can also flexibly select different operating modes to adapt to changes in power consumption, performance, and other requirements. The overall design ensures the stability and flexibility of the module in various application scenarios. The external drive circuit 4 of the ESP8266 is shown below. Figure 4As shown, the external driver circuit 4 is designed based on GPIO pins and is mainly used to control the switching operation of the LED. The GPIO pins serve as the interface between the microcontroller and external circuits, controlling external components by programming high-level or low-level signals. The LED (D2) is connected in series to the GPIO pin through a current-limiting resistor to protect the LED from damage caused by excessive current. The transistor (Q1) acts as a switching element in the circuit. When the GPIO output is high, the transistor conducts, and current flows through the collector and emitter to light the LED; when the GPIO output is low, the transistor is cut off, and the LED is off. The circuit also includes a +5V power supply and ground (GND) to provide a stable voltage for the system. A capacitor (C13) is used for filtering to reduce power supply noise interference. The entire circuit design is simple, ensuring efficient control of the LED and stable circuit operation.

[0045] Furthermore, the power supply circuit 3 includes a lithium battery charging circuit and a high-efficiency voltage regulator circuit. The lithium battery charging circuit and the high-efficiency voltage regulator circuit are respectively connected to the main control module 1. The lithium battery charging circuit includes a power supply VCC, a battery BAT, a charger CHG, a program controller PROG, an LED (D3) indicator light, and a capacitor. The power supply VCC, the D3 indicator light, and the charger CHG are connected. The battery BAT is connected to the power supply VCC, the program controller PROG, and the charger CHG. The capacitor is connected to the power supply VCC.

[0046] In this embodiment, the power supply circuit 3 consists of the lithium battery charging circuit and the high-efficiency voltage regulator circuit. The lithium battery charging circuit is based on a 4.2V lithium battery and integrates charging protection to ensure the safety and reliability of the battery. Figure 5As shown, the lithium battery charging circuit consists of key components such as the power supply VCC, the battery BAT, the charger CHG, the programmable controller PROG, the LED indicator, and the capacitor (330μF). The power supply VCC provides power to the entire circuit via connecting lines, and the charger CHG converts the input power into a suitable current and voltage for battery charging. The power supply VCC, connected to the charger CHG, has a rated voltage of 4.2V, while the programmable controller PROG monitors the charging status and ensures safe and efficient charging by adjusting the current and voltage. The LED indicator, connected to a resistor, provides visual feedback on the charging status; the light illuminates during charging and turns off or changes color when fully charged. The resistors and capacitors in the circuit filter and stabilize the voltage, reducing power fluctuations and protecting the battery and charger from damage caused by voltage instability. The ground point (GND) is connected at multiple points to ensure the electrical stability of the circuit. Overall, this circuit, through a reasonable component layout and connection, ensures efficient and safe charging of the lithium battery and allows the user to monitor the charging status in real time through the LED indicator and the programmable controller PROG.

[0047] The high-efficiency voltage regulator circuit includes a 3.7V to 5V circuit (boost circuit) and a 5V to 3.3V circuit (buck circuit) to power modules with different voltage requirements. Figure 6 As shown, this 3.7V to 5V boost circuit uses the SXI308 integrated circuit as its core, and achieves the boost function through the coordinated work of several key components. The input voltage VIN is connected to the input terminal of the SXI308 via the circuit board. The EN pin (enable pin) controls the switching of the circuit; when the EN pin is high, the circuit starts working. During the boost process, a 4.7uH inductor stores and releases energy to generate the required output voltage. Capacitors C14 and C15 smooth the voltage through filtering, ensuring a stable output voltage. Resistor R13 (73.2K) provides a feedback signal through the feedback pin FB. The SXI308 adjusts the charging and discharging process of the inductor based on the comparison between the feedback voltage and the internal reference voltage, maintaining the output voltage at 5V. The GND pin provides an electrical reference to ensure circuit stability. The SW pin, connected to the inductor, switches periodically during the boost process, ultimately outputting a stable 5V voltage to power the load. Figure 7As shown, this 5V to 3.3V buck converter uses a low-dropout linear regulator (LDO) – ME6211C33M5G – as its core, responsible for regulating the input 5V voltage to 3.3V, providing a stable power supply for subsequent circuits. The voltage regulator internally includes an error amplifier, a power transistor, and a feedback network. The error amplifier adjusts the conduction level of the power transistor by comparing the output voltage with a reference voltage, thereby maintaining a stable output voltage of 3.3V. In the circuit, capacitors C16 and C17 are used to smooth the voltage, reducing fluctuations and noise. Resistors are typically used for current limiting or voltage division, setting circuit parameters such as startup current or overcurrent protection. The GND pin provides a ground reference for the circuit, ensuring stability, while the NC pin indicates no connection, reserved for future expansion. The entire circuit achieves a stable buck function from 5V to 3.3V through precise adjustment.

[0048] Furthermore, the driving circuit 4 includes an LED lamp driving circuit 4 and a motor driving circuit 4, which are respectively connected to the main control module 1. The LED lamp driving circuit 4 includes a light-emitting diode, an integrated circuit chip AP3032KTR-G1, a resistor R14, an inductor L5, a capacitor C19, and a capacitor C20. The inductor L5, the capacitor C19, the capacitor C20, the light-emitting diode, and the resistor R14 are connected together. The integrated circuit chip AP3032KTR-G1 is connected to the resistor R14, the inductor L5, and the capacitor C19.

[0049] In this embodiment, the driving circuit 4 consists of the LED light driving circuit 4 and the motor driving circuit 4. The LED light driving circuit 4 controls the light emission state, brightness, or flashing mode of the LED by adjusting the settings of the integrated circuit chip or changing the state of the switch SW, and is used for navigation lights, status indicator lights, etc. of drones. Figure 8As shown, the LED driver circuit 4 consists of multiple light-emitting diodes (LEDs), an integrated circuit chip AP3032KTR-G1, a resistor R14, an inductor L5, a capacitor C19, a capacitor C20, and a switch SW. When the switch SW is closed, the LEDs are directly connected to the power supply VCC, thereby obtaining electrical energy and emitting light. The negative terminal (cathode) of each LED is connected to the integrated circuit chip AP3032KTR-G1 or ground (GND) through a common connection point, while the positive terminal (anode) is connected to VCC. The integrated circuit chip AP3032KTR-G1 plays a key role in the circuit, possibly acting as an LED driver to control the brightness, flashing mode, or color of the LED (such as RGB LEDs). This chip is connected to the power supply VCC through the resistor R14 and the capacitor C20; these two components are used to limit the current flowing into the chip and smooth the power supply voltage to protect the chip from damage. The switch SW is a manual control element used to turn the circuit on or off. When SW is in the open state, current cannot flow through the LED, and the LED will not light up. Conversely, when SW is closed, current flows through the LED, causing it to light up. Resistor R14 limits the current flowing through the integrated circuit chip to protect the AP3032KTR-G1 integrated circuit chip and the LED from damage due to excessive current. Capacitor C20 may be used to smooth the power supply voltage and reduce the impact of voltage fluctuations on circuit performance. Inductor L5 stores energy and releases it during switching operations.

[0050] The motor drive circuit 4 is used to control the motors of the drone. This circuit consists of multiple electronic components connected in a specific manner to form a complete system. At the top, there is a power port marked VCC, which provides power to the circuit. The circuit includes two transistors, D35 and D36, used to control the motor's start and stop, with B1 used for the motor itself. C21 is used to filter and smooth the power supply voltage for circuit protection. Next, indicator light D35 displays the circuit's operating status. Diode D36 is used for high-speed switching operation. Transistor Q2 plays a crucial switching or amplifying role, and resistor R17 regulates the current to Q2 to control the motor speed. Resistor R18 limits the current and protects the circuit. Q4 implements logic control and power amplification. Q3 controls the motor's forward and reverse rotation. Finally, the ground port GND at the bottom provides a common ground reference point.

[0051] Furthermore, the sensor peripheral circuit 5 includes a barometric altitude sensor and an attitude sensor.

[0052] In this embodiment, the sensor peripheral circuit 5 consists of the barometric altitude sensor and the attitude sensor. The barometric altitude sensor is used to measure the flight altitude of the UAV. The barometric altitude sensor is an electronic circuit schematic, powered by a 3.3V power supply, and contains several key electronic components to form a complete circuit system. The power supply has two 3.3V input ports to provide the required power, and a GND ground port at the end as a common ground reference point. The core of the circuit is the BME280 / BMP280 integrated circuit, which is the main control element. Resistors R20, R21, R22, R23 and capacitors C22, C23 are connected around it for filtering, voltage division, and current limiting. Pins CSB (chip select), VDD (power supply), SDI (serial data input), SDO (serial data output), and SCK (serial clock) of U1 are used for data communication and control. Resistors R20, R21, and R22 act as pull-up or pull-down resistors to ensure that the sensor maintains a stable level when idle.

[0053] The attitude sensor is used to acquire the attitude information of the UAV. The attitude sensor circuit consists of three circuits: the first, second, and third circuits, which are described respectively for basic connections and power supply, detailed connections and functional pins, and additional components and adjustments. The basic framework of the attitude sensor circuit is shown, mainly including the power supply section and basic connection lines. The first circuit diagram clearly marks VCC_3.3V and GND, representing the 3.3V power supply voltage and ground line, respectively. VCC_3.3V provides the necessary power to the sensor and other electronic components, while GND serves as the common reference potential for the circuit. The main function of this diagram is to ensure the normal operation of the sensor and provide a unified potential reference, allowing the sensor to connect to external circuits through its pins to achieve data transmission and control signal reception. The second circuit diagram further details the connection details and functional pins of the attitude sensor circuit. This diagram clearly shows the two key pins: the synchronous clock line SCL and the data line SDA, which are typically used for communication with microcontrollers or other data processors. In addition to these two pins, the diagram also shows other functional pins, such as AUXDA, AUXCL (another set of data and clock lines), AD0 (address selection pin, used to set the sensor's I2C address), and INT (interrupt pin, used to trigger an interrupt signal under specific conditions). The main function of this diagram is to enable data communication between the sensor and the microcontroller, transmitting data via I2C or a similar protocol to ensure effective collaboration among the various components in the system. The third circuit diagram, based on the first two diagrams, adds an additional electronic component—resistor R27—for adjusting the current or voltage in the circuit.

[0054] The primary function of this circuit is to limit current, divide voltage, or provide other circuit functions through resistor R27, ensuring that the sensor operates within a safe current and voltage range. Additionally, additional components and signal conditioning circuitry can be used to enhance sensor performance, improve data accuracy, or reduce noise interference. By adjusting the parameters of these components, the sensor's output signal can be optimized to meet the needs of specific applications.
