Intelligent walking stick for tumbling remote monitoring and nursing

Abstract

The invention provides an intelligent walking stick for tumbling remote monitoring and nursing. A battery main switch, function keys, a display screen and indicator lights are arranged on a walking stick handle. A wireless communication module and a buzzer are internally arranged on the upper portion of a walking stick supporting body, an antenna which is connected with the wireless communication module is placed on the surface of the walking stick supporting body, and an acceleration sensor, a GPS module, a microprocessor and a battery are integrally arranged on the lower portion of the walking stick supporting body. The acceleration sensor is used for being responsible for collecting the motion acceleration of the walking stick, then the microprocessor is used for processing and judging tumbling information, the GPS module is used for tracking the positional information of the walking stick in real time, and when tumbling is detected or an alarm is given actively through the function keys, the microprocessor sends the positional information of the walking stick and alarm signals. According to the intelligent walking stick, a multi-innovation Kalman filtering method is adopted, the information returned by the acceleration sensor is processed, noise signals are eliminated, so that whether an old man / woman tumbles or not is accurately judged, and accurate warning is achieved; through the function of GPS positioning and the function of buzzer warning, a user of the walking stick can be treated and cured conveniently in time.

Description

Technical field [0001] The invention relates to an intelligent crutch, in particular to an intelligent crutch for remote fall monitoring used by the elderly. technical background [0002] With the deepening of the aging of society, there are more and more empty-nest elderly people, which has become a social problem that cannot be ignored. They have no children to take care of and require more and more security guarantees for their lives. The ever-increasing number of "empty-nest elderly" has caused the existing elderly care system to face three major challenges: life security, daily care services, and spiritual comfort. [0003] In recent years, wearable devices have gradually entered the public eye and have become a new development trend. Wearable technology mainly explores and creates a device that can be worn directly on the body or integrated into user clothes or accessories. For example, Google Project Glass, which has the same functions as a smart phone, can control photos,...

AI Technical Summary

Problems solved by technology

However, these crutches with fall detection function lack the processing of the original signal of the sensor, especially the information returned by the acceleration sensor often has a strong noise interference signal, which is prone to false alarms
