Problems solved by technology

[0002] It is common for the elderly to live alone in an aging society, and the elderly often cannot effectively call the police when they have accidents (such as wrestling)
In the past, the elderly care system or similar alarm and help systems used contact devices or wearable devices or camera equipment. There is a certain violation, or it must be worn on the body to increase the psychological burden of the elderly
Therefore, the application and promotion of similar systems are not effective
[0003] In addition, there is a technology to detect the state of the elderly through infrared temperature sensors, but this technology can only detect the temperature of dynamic human body and single point area, and cannot detect static human body and dynamic human body at the same time, and cannot detect multi-point positions (matrix area) The temperature changes at each point, so the degree of intelligence is not enough
[0004] In addition, one of the main reasons for the old man to fall is the lighting problem. In the prior art, there is no lighting device that can be automatically turned on and off when the old man gets up at night and walks.

Embodiment 1

[0034] Example 1: Automatic lighting control at night

[0035] Such as Figure 4 As shown, in this embodiment, the system is installed on the opposite side of the elderly bed, and the computer is used to present the monitoring data on the computer screen. The first row of the table on the computer screen is the highest value of each cell measured by the 1*8 infrared array temperature sensor. The temperature value, the grid with a value higher than the reference value will be marked with red. Because the surface temperature is much lower than the reference value, the rest of the grids are all white. Among them, the setting of the reference value is set by the result of the difference analysis of the environmental temperature value sensed by the system and the temperature change of each area.

[0036] When a person sits up, there is a grid marked red on the computer screen, indicating that the person's body has entered the detection range of the sensor. In practical applications, th...

Embodiment 2

[0037] Example 2: Call for help under abnormal conditions

[0038] In this embodiment, the present invention is fixed above the ceiling, and the 4*4 infrared array sensor is activated, so that the infrared array sensor faces directly below, so as to monitor the area directly below it, and the detection data is displayed on the computer screen. Set the alarm conditions as follows: 1. There are no less than three continuous areas (grids) marked red; 2. These grids do not change color within 5 seconds and no new red grids appear.

[0039] by Figure 5 It can be seen that when a person is standing, only one grid is marked red and the system does not alarm; when the human body is lying down, there are five grids marked red, and when the time exceeds 5 seconds, the system will alarm. The results show that during the application process, when the system detects that the temperature in a continuous area on the horizontal plane is higher than the reference value and the duration exceeds th...

Abstract

The invention discloses an elderly people living alone-oriented intelligent lighting and alarm system. According to the elderly people living alone-oriented intelligent lighting and alarm system disclosed by the invention, trace infrared rays emitted from a human body are monitored by adopting a passive infrared sensor array, and therefore, human body localization and human body tracking are realized; states of elderly people can be identified during general activities and at the time that an accident occurs, and an alarm is given automatically when unforeseen circumstances occur; the elderly people living alone-oriented intelligent lighting and alarm system is used for nursing on the elderly people living alone; as the elderly people living alone-oriented intelligent lighting and alarm system is a non-contact elderly people nursing system, private lives of the elderly people are not influenced, the repulsion of the elderly people cannot be caused, and convenience is provided for the lives of the elderly people while nursing is realized. The elderly people living alone-oriented intelligent lighting and alarm system disclosed by the invention is not harmful to health, and is environmentally friendly and energy-saving.

Description

Technical field [0001] The invention relates to an intelligent lighting and alarm system for elderly people living alone. Background technique [0002] The phenomenon of elderly people living alone in an aging society is common, and the elderly often cannot effectively report to the police when accidents (such as wrestling) occur. In the past, the elderly care system or similar alarm and help systems used contact devices or wearable devices or camera instruments. These applications have certain drawbacks. While realizing the care of the elderly, it is inevitable or privacy for the elderly. There is a certain violation, or it must be worn on the body to increase the psychological burden of the elderly. Therefore, the application and promotion of similar systems are not effective. [0003] In addition, there is a technology to detect the state of the elderly through infrared temperature sensors, but this technology can only detect the temperature of a dynamic human body and a singl...
