Human body falling monitoring method and device based on acceleration and height information

Abstract

The invention discloses a human body falling monitoring method and a device based on acceleration and height information. The device comprises a sensing module, a processing and controlling module, a communication module, a wear detecting module and a power supply module. The sensing module provided with an accelerometer and a height gauge is connected with the processing and controlling module based on a low power consumption single chip computer, and continuously monitors the acceleration and height change of a wearer in daily activities. The wear detecting module checks the wearing method of the device. The processing and controlling module starts a bluetooth communication module to send alarm information when the device judges that the wearer falls according to collected acceleration and height data. A wearing buckle capable of being placed on a waistband of the wearer comprises a magnet, and therefore the device is capable of inspecting whether position-wearing is achieved. The human body falling monitoring method and the device based on the acceleration and the height information has the advantages that falling occurrence can be found accurately and timely by means of combination of continuously monitored acceleration information and height information, energy consumption is reduced by means of a low-power design and high energy efficiency management, and therefore long-term and continuous working is achieved.

Description

technical field [0001] The invention relates to a human body fall monitoring method and device based on acceleration and height information, in particular to a device and method capable of continuously detecting whether a human body has fallen over a long period of time, and is mainly applicable to the fall monitoring of the elderly. Background technique [0002] In the 21st century, population aging will become more apparent. With the development of the economy and the exchange of cultures, the mobility of the population has been greatly accelerated, so that many children are not with the elderly. Therefore, the health and medical care of the elderly has gradually become a major problem, and the health status of most elderly people cannot be monitored in time. In the event of an accident, if the elderly do not receive immediate assistance, it may even threaten their lives. Falls are common among the elderly. [0003] The fall of the elderly will cause many safety problem...

AI Technical Summary

Problems solved by technology

CN2249072Y mainly detects falls based on mercury switches; CN201127606Y and the like use only acceleration information for fall detection; site, inconvenient to use and increased cost

The main disadvantage of the existing wearable fall detection methods is that the power consumption of the system is generally relatively large, and it is difficult to continuously monitor for a long time. The fall detection technology is mainly based on the acceleration and angle change information, and does not take advantage of the inevitable
