Embodiment

[0052] The invention provides an indoor fall intelligent sensing system for real-time monitoring of indoor personnel falls, including an intelligent floor and a signal processor, wherein the intelligent floor is such as Figure 4 Shown is the floor 7 embedded with the piezoelectric sensing layer 8 . This intelligent sensing system is based on the piezoelectric sensing film 6. This material will generate different electrical signals when subjected to different pressures. Transmitting these electrical signals to the signal processor can monitor the force on it in real time. . When the system judges that there is a fall, the vital signs monitoring module is triggered, and the sensor film monitors the breathing and heartbeat of the person who fell and transmits it to the cloud in real time, and sends real-time data to the APP terminal (including nursing centers, emergency centers, guardians, etc.) . The invention can realize the perception of falling and the accurate positioning...

Abstract

The invention relates to an indoor fall intelligent sensing system, which includes an intelligent floor and a signal processor. The intelligent floor is a floor embedded with a piezoelectric sensing layer, and the piezoelectric sensing layer includes a plurality of mutually independent and the piezoelectric sensing films respectively connected to the signal processor, the piezoelectric sensing films are interwoven to form a two-dimensional plane coordinate network; the signal processor monitors the stress of each piezoelectric sensing film in real time, When a fall occurs, multiple piezoelectric sensing films passing through the place of the fall detect the change of the force situation at the same time, and send it to the signal processor through an electrical signal, and the signal processor The force of the situation, and use the two-dimensional plane coordinate network formed by the piezoelectric sensing film to locate the location of the fall, and finally send a help message. Compared with the prior art, the present invention can realize the fall without additional positioning system Accurate positioning of perception and location, and real-time monitoring of the vital signs of the person who fell.

Description

technical field [0001] The invention relates to the field of intelligent sensing technology, in particular to an indoor fall intelligent sensing system and a preparation and control method thereof. Background technique [0002] China is the country with the largest aging population in the world. According to the population data released by the National Bureau of Statistics, as of the end of 2018, my country's population aged 60 and above was 249.49 million, that is, the number of elderly people in my country was as high as 249 million. How to support the elderly and how to protect the health of the elderly has become a hot issue in society. [0003] An important factor that endangers the health of the elderly is indoor falls. According to the report of the World Health Organization, about 150,000 elderly people die from falls every year in the world, and more than 40 million elderly people in my country fall at least once every year. At the beginning of 2013, Longhua Sub-d...
