Embodiment Construction

[0057] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0058] According to an embodiment of the present invention, a wearable human body sensor monitoring device based on a nine-axis inertial measurement unit is proposed. The elderly wear the device on the wrist or above the elbow through a wristband, and turn on the device to record real-time information of the elderly. heart rate, body temperature and blood oxygen levels, while monitoring the walking conditions of the elderly, and always tracking whether there is a fall. The microprocessor module is programmed based on single-chip microcomputer technology, so that the device has a real-time operating system. The device has a corresponding Android application, and the microc...

Abstract

The invention discloses wearable human body sensing and monitoring equipment based on a nine-axis inertial measurement unit, which comprises a power module, a sensor module, the nine-axis inertial measurement unit, a microprocessor module, a Bluetooth communication module and a mobile phone terminal, wherein the nine-axis inertial measurement unit integrates a three-axis accelerometer, a three-axis gyroscope and a three-axis magnetometer, is worn on the wrist of a user and used for detecting posture conditions of the user in the X direction, the Y direction and the Z direction of a preset three-dimensional coordinate system and judging the normal state of the human body and an accidental falling event by resolving multi-source data and combining a mode recognition method; the nine-axis inertial measurement module is mainly used for collecting human hand motion related parameters and processing the motion parameters to restore the spatial posture of a motion limb; and the motion parameters describing the motion limb comprise acceleration, corresponding joint rotation angular velocity and magnetic field information of the limb in a corresponding space.

Description

technical field [0001] The invention relates to the field of sensor measurement, in particular to a wearable human body sensor monitoring device based on a nine-axis inertial measurement unit. Background technique [0002] With the development of smart wearable technology, it is becoming easier and more popular to provide continuous healthcare for the elderly. Autonomous systems that can provide people with rapid and continuous health status monitoring are undoubtedly very attractive. Such systems can help the elderly improve their health and reduce society's health costs for the elderly. Retrieving the technical solutions that have been developed, it can be found that such systems are dedicated to monitoring important parameters such as electrocardiogram (ECG), pulse and oxygen saturation, blood pressure, etc. at home and in outdoor environments, and have the ability to directly The ability to alert a hospital or doctor. Some important parameter sensing platforms such as ...
