Intelligent Solar-Powered Ground Lock System Design for Fire Lanes

An intelligent ground lock device is designed to address the issue of insufficient parking spaces leading to the obstruction of fire lanes. The device, centered around the STM32F103C8T6 microcontroller, manages the rising and lowering of a barrier through the control of the SG-90 servo motor’s angular displacement. This effectively prevents unauthorized parking and ensures passage for emergency vehicles. Additionally, it integrates the HC-05 Bluetooth module, enabling remote control via a smartphone for management personnel. The system also adjusts the on/off state of warning LEDs using a BH1750 light sensor. To prevent vandalism, the device features a sentry mode that triggers an alarm through a buzzer and sends alert information to the user's phone for easier maintenance. Furthermore, the device is equipped with a solar panel to collect solar energy, providing a continuous 24-hour power supply, which ensures operational continuity while achieving energy-saving and emission-reduction goals.
