Fall-down monitoring system with voice communication function

Abstract

The invention discloses a fall-down monitoring system with a voice communication function. The system includes a fall-down monitoring terminal and a guardianship terminal, which are in communication through a communication network. The fall-down monitoring terminal includes a microprocessor, a data acquisition unit, an audio modulation chip, a voice communication button and a wireless communication module A. The audio modulation chip is connected with an audio signal I / O port of the microprocessor. The microphone and a loudspeaker are connected with the audio modulation chip respectively. The wireless communication A is connected with the microprocessor. The voice communication button is arranged on a casing of the fall-down monitoring terminal and connected with the microprocessor. The data acquisition unit includes a pressure acquisition subunit, an acceleration acquisition subunit and an angular speed acquisition subunit. The fall-down monitoring system with the voice communication function has remote monitoring and voice communication functions and adopts the wearable fall-down monitoring terminal so that the system is convenient to carry; the system judges whether a person under guardianship falls down through combination of a plurality of sensors so that accuracy is high; and the system is capable of timely cancellation under a condition that a false alarm happens so that unnecessary troubles are avoided.

Description

technical field [0001] The invention relates to a fall monitoring system with voice communication function. Background technique [0002] China's population aging situation is grim, showing three major characteristics: accelerated population aging, aging population and empty-nest. With the continuous development of social aging, the proportion of empty-nest elderly families will become higher and higher. According to statistics, in Among the elderly population, more than 1 / 3 of the people experience falls every year, and the primary cause of accidental injuries in the elderly is falls. Accidental slips or the sudden onset and deterioration of certain diseases may lead to falls. When a fall occurs, If timely rescue cannot be obtained, delaying the timing of rescue will endanger life. Therefore, it is of great significance to develop a fall monitoring system for the elderly, and to report to the police or contact the guardian in time when a fall event occurs without affecting...

AI Technical Summary

Problems solved by technology

[0003] At present, the main means of fall detection for the elderly are: ① installing video surveillance equipment, which is expensive and inconvenient to carry, and cannot protect the personal privacy of the elderly; ② distinguish between daily life events and For fall events, this method has high requirements on the environment and poor adaptability. For different grounds, the performance of fall detection is unstable

Further, in the prior art, a fall monitoring device that can be worn at any time has also appeared, which mainly judges the occurrence of a fall event through acceleration detection, but there are still the following deficiencies: (1) Due to the complexity of the daily human behavior The information of the sensor is used to judge the fall event, which is prone to misjudgment and the judgment accuracy is poor; (2) The acceleration sensor is often placed at the waist position, and the change of the acceleration at the waist position is relatively small, making the monitoring of the acceleration information accurate (3) It only sends alarm information and does not have the function of voice communication. In an emergency, it cannot communicate with the guardian by voice, and cannot take some necessary first aid measures in time to minimize the injury
