ZigBee-based portable human falling detection and warning system

Abstract

The invention relates to a ZigBee-based portable human falling detection and warning system, which comprises a microprocessor, an acceleration transducer, an information acquisition and emission module, a wireless receiving module, an upper computer software module, an alarm and a power supply, wherein the microprocessor is connected with the acceleration transducer, the information acquisition and emission module, the alarm and the power supply respectively; the information acquisition and emission module is sequentially connected with the wireless receiving module and the upper computer software module through ZigBee wireless information transformation; the measurement direction of the acceleration transducer is triaxial; an output signal of the acceleration transducer is an analog signal or a digital signal; a coordinator node, a data receiving node and an upper computer of the wireless receiving module are connected through a serial port; and the upper computer is connected with a server through an internet interface. The ZigBee-based portable human falling detection and warning system has high sensitivity, and can timely detect the human posture of a person under guardianship, coordinating positioning, falling time and warning time and transmit to the upper computer software module in a wireless transmission way, so that a guardian can obtain the emergency condition timely and take a rescue measure.

Description

technical field [0001] The invention relates to a ZigBee-based portable human body fall detection and alarm system, which is used for real-time evaluation and alarm of sudden changes in human motion state, so as to facilitate timely rescue. Background technique [0002] When some accidents happen to the elderly at home or individuals with poor self-care ability in places where the elderly gather, they often cannot get timely treatment and rescue. Among the many accidents, there is one type of accident that is very representative-sudden movement state. Here, the mutation of the motion state refers to the rapid change of body posture caused by external force or self-coordination problems. The research on the mutation of the motion state is more about the detection of falls. For the human body, rapid changes in motion state may cause harm to the human body. Therefore, how to quickly detect these sudden changes in motion state and call the police is very important for quickly g...
