Development of a Vertical Acceleration Sensor Based on Embedded Systems

This paper analyzes the acceleration detection requirements of the traveling block system and proposes an acceleration detection scheme using the traveling block as the target. An implementation plan based on the STM32 microcontroller and RS485 wired communication was developed. The hardware circuit and PCB design were carried out using components such as the STM32 microcontroller and MPU6050 gyroscope chip. Data acquisition and display were achieved through SPI and I2C communication implemented in software, while data was transmitted via wired communication using hardware UART peripherals. An experimental platform was built to test acceleration detection and wired data transmission. Compared with other design schemes, this design fully considers the impact of attitude changes on vertical acceleration detection, optimizing the sensor's detection algorithm and hardware design. It provides a technically valuable reference for engineering applications in related fields.
