[0025] like Figures 1-3The diagram shows a main power control circuit for a golf simulation system detector, including a power supply regulator comprising a first-stage step-down regulator, a second-stage step-down regulator, and a third-stage step-down regulator. The first-stage step-down regulator is connected to the second-stage step-down regulator, and the second-stage step-down regulator is connected to the third-stage step-down regulator. The first-stage step-down regulator converts the VCC24V voltage to an SW5V voltage output for use. The SW5V voltage output supplies power to a chip with a corresponding voltage (e.g., the SW5V voltage output supplies power to the digital signal processor U3 in the internal circuit of the golf simulation system detector), and simultaneously supplies power to the next-stage step-down regulator for secondary voltage reduction. The second-stage step-down regulator converts the SW5V voltage... The power supply is stepped down to the SW3V3 voltage output, which then supplies the corresponding voltage to the chips (e.g., the microcontroller chip U1, digital signal processor U3, flash memory chip U5, and hub controller chip U24 in the golf simulation system detector's internal circuitry). Simultaneously, it supplies the next stage of the power supply step-down regulator for further step-down. The third-stage power supply step-down regulator then steps down the SW3V3 voltage to the SW1V1 voltage output, which in turn supplies the corresponding voltage to the chips (e.g., the digital signal processor U3, flash memory chip U5, and hub controller chip U24 in the golf simulation system detector's internal circuitry). This product, through its three-stage voltage regulation and step-down structure, provides stepped-down voltages to different circuits, adapting to the varying voltage requirements of each circuit. This effectively ensures the stable operation of the system's core circuits (chips) under different operating voltages, significantly improving power conversion efficiency and system anti-interference capabilities. This design rationally allocates the power load, reducing overall power consumption while enhancing circuit reliability and long-term operational stability, meeting the high-precision, low-latency real-time computing requirements of the golf simulation system detector. Furthermore, the small voltage difference between SW5V and SW3V3, and between SW3V3 and SW1V1, results in low power consumption and low temperature during voltage conversion, reducing heat loss. The smaller voltage difference also means less output voltage fluctuation, faster load response, and less ripple, maintaining a more stable output voltage and smoother voltage conversion, further improving energy efficiency. This makes it suitable for scenarios with high stability requirements (e.g., golf simulation system detection). The smaller voltage difference also reduces the specifications required for power components, simplifying the parameter design of inductors and capacitors, and lowering system cost. Simultaneously, it more effectively suppresses power ripple and external electromagnetic interference, ensuring stable operation of the golf simulation system detector's internal sensitive analog circuitry and high-speed digital circuitry.

[0028] The inductive reactance of inductor L7 filters out high-frequency interference signals in the output signal, maintaining the stability of the DC output. In signal processing circuits, inductor L7 adjusts the impedance of the output signal to ensure stable signal reception by the load device. In switching power supply scenarios, inductor L7 stores and releases magnetic field energy to help achieve smooth transient current output. Inductor L7, along with decoupling capacitor C71 and electrolytic capacitor C73, constitutes a filter. Pin 2 of the switching power supply buck regulator U39 uses an external resistor R217 and resistor R218 voltage divider network to regulate the output voltage. By properly configuring the resistance ratio of resistors R217 and R218, the output voltage can be precisely set to 5V, meeting the power supply accuracy requirements of subsequent circuits. Resistors R219 and R220 provide voltage division or current limiting protection for the MAIN_PWR power switch signal line, stabilizing the voltage signal of the MAIN_PWR power switch signal line. Pin 5 of the switching power supply buck regulator U39 is the ON / OFF pin, a key pin used to control the start / stop of the circuit in the switching power supply buck regulator U39. When this MAIN_PWR power switch signal line pin is grounded, the switching power supply buck regulator U39 is off. When the MAIN_PWR power switch signal line is disconnected from ground, the switching power supply buck regulator U39 enters the working state, realizing the power supply on / off control, and also controlling the switches of the secondary and tertiary power supply buck regulators. When the primary power supply buck regulator is off, the secondary and tertiary power supply buck regulators are also off. Conversely, when the primary power supply buck regulator is started, the secondary and tertiary power supply buck regulators are also powered on.

Electrolytic capacitor C72 is mainly used for input filtering, smoothing input voltage fluctuations, reducing ripple interference, and ensuring stable operation of the load circuit. Electrolytic capacitor C72 stores energy, absorbing excess energy when the input voltage is high and releasing energy when the voltage is insufficient, thereby reducing voltage fluctuations and improving power supply stability. Decoupling capacitor C70 is mainly used to filter out high-frequency noise interference and stabilize the supply voltage. Decoupling capacitor C70 absorbs high-frequency AC components on the power line and conducts this noise to the ground line, thereby reducing power supply voltage fluctuations. For high-precision circuits, decoupling capacitor C70 can significantly improve power supply stability and reduce the risk of circuit malfunctions caused by noise. Electrolytic capacitor C75 is mainly used to stabilize the output voltage, filter, and improve transient response capability, ensuring stable output voltage by smoothing voltage fluctuations. This dual-stage power supply step-down regulator has a small voltage difference between the input and output voltages, low power consumption, and low temperature during voltage conversion, reducing heat loss. The small voltage difference means less output voltage fluctuation, faster load response, less ripple, and a more stable output voltage.
