Abstract: According to the existing problem in position detection system of container spreader,including low handling efficiency highly cost,this paper investigates a position detection system of container spreader based on MEMS sensors.The system consists of the sensor data acquisition modules,the micro-controller and real-time dynamic monitoring.Sensor data acquisition modules contain the LSM303DLHC sensor and the L3GD20 sensor;micro-controller is STM32F303;the real-time dynamic monitoring is the PC interface.The gesture fusion algorithm based on gradient descent is analyzed.Comparison of the experimental data and analysis of the tracking monitoring interface show that the proposed system has good real-time performance,high accuracy and friendly interface.The system has been fully validated in related subjects.
