Problems solved by technology

[0006] However, the non-contact indoor occupant fall recognition method in the prior art is based on the construction of the home broadband network, occupying the bandwidth of the home broadband network
At the same time, for the connection of infrared sensors, if a Wi-Fi wireless connection is used, some rooms cannot be covered, and the communication effect is not stable enough. If a wired connection is used, the wiring is more troublesome and the deployment cost is higher
In addition, for households without Internet connection, such as remote rural areas, it is impossible to implement

Embodiment Construction

[0019] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings, so that those skilled in the art can better understand the present invention. It should be noted that in the following description, when detailed descriptions of known functions and designs may dilute the main content of the present invention, these descriptions will be omitted here.

[0020] figure 1 It is a schematic diagram of fall recognition based on infrared thermal imaging sensor.

[0021] Such as figure 1 As shown, an infrared thermal imaging sensor is installed above the indoor monitoring area to monitor human posture ( figure 1 shown on the left), the captured (acquired) infrared thermal image including thermal information of indoor personnel is as follows figure 1 It is shown on the right, where (a) is the infrared thermal image of the standing posture, and (b) is the infrared thermal image of the falling posture. from figure 1 , we can se...

Abstract

The invention discloses a non-contact indoor personnel falling identification method based on an Internet of Things platform, and the method comprises the steps: transmitting a captured infrared thermal image comprising indoor personnel thermal information to a cloud server in real time through an NB-IoT narrow-band wireless communication module, and returning the personnel fall-down alarm information to a monitoring device installed in an indoor monitoring region; two-way wireless connection, no local gateway, no central network and industrial-grade system reliability are realized, so that connection with a home broadband network is not needed, and wide-coverage non-contact indoor personnel fall-down identification is realized. According to the invention, NB-IoT narrow-band transmission infrared thermal image resolution is acquired through infrared thermal image low resolution, human body posture feature extraction is enhanced, falling information is returned to a guardian mobile phone through falling, alarm information is sent to an alarm device, and an alarm sound is emitted, so that intelligent and rapid falling behavior identification is realized.

Description

technical field [0001] The invention belongs to the technical field of fall recognition, and more specifically relates to a non-contact indoor person fall recognition method based on an Internet of Things platform. Background technique [0002] With the intensification of China's population aging, the issue of health care for the elderly has become one of the hotspots of general concern in society. By the end of 2019, my country's population aged 65 and over had exceeded 176 million, accounting for 12.6% of the total population (National Bureau of Statistics, 2019 Population Survey). According to the United Nations standard, the population aged 65 and over accounts for 14% of the total population, that is, the region is considered to have entered an "aging society". Taking 14% as the dividing line, at the end of 2019, my country was only 1.4% away from the "aging society". In 2018, Sichuan, Jiangsu, Chongqing and other provinces in my country have crossed the 14% line, that...
