Device for recognizing human lower limbs movement posture by virtue of combined sensor

Abstract

The invention relates to a device for recognizing a human lower limbs movement posture by virtue of a combined sensor. The device comprises a data acquisition module, a signal conditioning module, a micro-controller module and a wireless communication transmission module, and further comprises a wireless communication receiving module and a posture analyzer, wherein the data acquisition module, the signal conditioning module, the micro-controller module and the wireless communication transmission module are sequentially connected by virtue of a lead wire, and the data acquisition module is used for acquiring a human lower limbs movement posture signal, the signal conditioning module is used for processing the data signal, the micro-controller module is used for controlling and coordinating the entire system and the wireless communication transmission module is used for transmitting data; the data acquisition module, the signal conditioning module, the micro-controller module and the wireless communication transmission module are respectively connected to a power module which is used for supplying power to the modules so that the modules can work normally by virtue of lead wires; the wireless communication receiving module is used for receiving the data; and the posture analyzer is connected to the wireless communication receiving module by virtue of a data line. The device disclosed by the invention is reliable to use, and is capable of acquiring human lower limbs movement posture information; and the device has the characteristics of being concise and convenient.

Description

Technical field [0001] The invention relates to the application field of sensors, in particular to a device based on a two-axis or three-axis acceleration sensor and a flexible sensor for identifying the movement posture of the lower limbs of the human body. Background technique [0002] The human body's lower limb motion posture capture is mainly based on two types of methods: a capture system based on video images and a capture system based on wearable sensors. [0003] The video image-based capturing system captures the human body motion picture through one or several video cameras, and determines the human body motion and the human body motion posture through a specially designed image processing algorithm. However, a video-based capture system usually can only perform video capture and recognition at the location where a specific camera is installed because the camera is installed in a fixed location. The human body is a moving object. When the subject leaves the detectable r...

However, video-based capture systems usually only perform video capture and recognition at the location where a specific camera is installed because the camera is installed in a fixed location

The human body is a moving object. When the detected person leaves the detectable range of the video camera, the system cannot realize data collection and motion capture.

In addition, light and reflection can also cause data errors, and may also cause leakage of personal privacy to the detected person
