Human body physiological status test intelligent helmet based on multi-sensor fusion and system

Abstract

The invention relates to a human body physiological status test intelligent helmet based on multi-sensor fusion and a system. The helmet comprises a movement path detection unit, a myoelectricity sensor, a body temperature sensor, a heat release pulse wave sensor and a central processing unit, wherein the movement path detection unit is used for detecting the acceleration, the speed and the displacement of the human body; the myoelectricity sensor is used for collecting the human electromyographic signals; the body temperature sensor is used for collecting the human body temperature; the heat release pulse wave sensor is used for collecting the human body pulse signals; the central processing unit is used for calculating the human body physiological parameters according to the electromyographic signals, the body temperature and the pulse signals, calculates the human movement path according to the acceleration, the speed and the displacement, and sends the human body physiological parameters and the movement path to an intelligent terminal for alarming. An outdoor sporter wears the intelligent helmet, accurate tracking positioning and physiological parameter detection can be performed anytime and data can be uploaded to the intelligent terminal timely according to the intelligent helmet, and when an abnormal change occurs to the physiological parameters, early warming can be triggered and positioning and abnormal information can be received by others in the first time.

Description

technical field [0001] The invention belongs to the technical field of body area networks, and in particular relates to a multi-sensor fusion-based smart helmet and system for detecting human physiological states. Background technique [0002] The smart helmet belongs to the category of wearable devices. It is a smart device with body area network technology integrated by electronic technology, computer technology, network communication technology and signal processing technology. The smart helmet first originated from the GPS positioning system. At that time, in order to solve specific engineering needs for users, the system provided additional functions such as location information, safety judgment, service assistance judgment, and voice communication on the basis of the original positioning function. The smart helmet not only simply provides the user with real-time GPS information and image information around the user, but also provides in-depth calculation of the collect...
