Human body posture recognition system based on flexible pressure sensor array

The invention belongs to the technical field of sensor measurement, and particularly relates to a human body posture recognition system based on a flexible pressure sensor array. The joint pressure and the falling state are collected through the sensor module, the signal processing module carries out filtering, denoising and weighting processing, the wireless transmission module sends data in a wireless mode, and the upper computer recognizes the posture through an improved dynamic time warping algorithm. The system comprises a flexible pressure sensor array and an acceleration sensor, the sensor array is attached to the joint, and the acceleration sensor detects acceleration changes. The signal processing module is composed of a row-column gating switch, a voltage conversion module, an ADC and an STM32 main control chip, the wireless transmission module is a Bluetooth module, and the upper computer is matched with a preset posture sequence through an algorithm. The system improves the recognition rate, is hi
