Problems solved by technology

[0003] At present, there are mainly two types of fall monitoring methods for the elderly: the first method is to use cameras or infrared thermal imaging sensors to collect human body images, and perform shape recognition through image processing technology to determine whether the user has fallen. This method does not need to be detected Users wear designated equipment, but it is easy to leak user privacy
The second type of method is to use an acceleration sensor to detect the acceleration of the human body to determine whether the user has fallen. This method requires wearing a device and is inconvenient to use

Embodiment 1

[0045] see figure 1 , a fall detection system for the elderly in key areas, comprising: a detection module, a main control module, a help module, an alarm module and a release module. The detection module here is a laser radar, which can be flexibly placed in key detection areas, such as the bathroom, beside the bed, in front of the sofa, etc., located at the height of the waist of a person, periodically detects key areas, and transmits the collected distance information to Main control module, the main control module recognizes the physical characteristics of falling according to the fall detection method. If it is detected as a falling state (falling physical characteristics and lasting for a certain period of time), the alarm module triggers an alarm sound, and the help module pushes through SMS or Internet Notify the family member's mobile phone terminal that the release module is a button in this embodiment. When a false alarm is generated, the old man can cancel by press...

Embodiment 2

[0047] see Figure 2-4 , a fall detection method for an elderly person in a key area, comprising the following steps:

[0048] Periodically detect key areas and collect distance information;

[0049] Detect and identify distance information based on the fall detection method;

[0050] If it is detected as a fall state, the alarm state will be triggered, and the alarm message will be wirelessly transmitted to the designated terminal, otherwise the alarm operation will not be executed;

[0051] After receiving the user's release instruction, the alarm state is released, and the false alarm message is wirelessly transmitted to the designated terminal.

[0052]Among them, the detection module is a laser radar placed in a key detection area, and its placement height is the height of the waist of a human body. The key detection area includes the toilet, bedside and in front of the sofa; wireless transmission includes text messages, phone calls, and Internet pushes. The designated...

Embodiment 3

[0065] The embodiment of the present invention also provides a fall detection device for the elderly in a key area, including a processor and a storage medium;

[0066] The storage medium is used to store instructions;

[0067] The processor is configured to operate according to the instructions to execute the steps of any one of the methods in the second embodiment.

Abstract

The invention discloses a system and method for detecting falling of old people in a key area in the field of monitoring and early warning, and the system comprises a detection module which periodically detects the key area, collects distance information, and transmits the distance information to a main control module, a main control module that detects and identifies the distance information based on a tumble detection method, and transmits an alarm signal to the alarm module and the help seeking module if a tumble state is detected, and a help seeking module used for wirelessly transmitting the alarm message to a specified terminal based on the alarm signal. According to the invention, through detection and early warning of the key area, timely feedback of the falling condition of the old people is realized, in addition, through detection of falling of the old people in the key area by the laser radar, the problem that the old people do not know the falling condition at home and misses the optimal rescue opportunity is solved, and the system does not leak privacy, does not need to wear and is very convenient. Through the tumble detection method, tumble of the old people can be quickly and accurately identified, automatic alarm and alarm release functions are realized, the problems of missing alarm and false alarm are solved, and the system reliability is improved.

Description

technical field [0001] The invention relates to a fall detection system and method for an elderly person in a key area, and belongs to the technical field of monitoring and early warning. Background technique [0002] As the age increases, the probability of accidental injury in the elderly gradually increases. According to a report released by the World Health Organization, more than 300,000 people die from falls every year in the world, of which more than half are people over the age of 60. Among the accidents of elderly people falling, the proportion of falling at home is more than 51.5%. The incidence of complications after falls in the elderly is high and the severity is high. Soft tissue damage in mild cases, fractures, cerebral hemorrhage and even death in severe cases. Missing the best treatment time happens from time to time due to failure to contact family members in time. Therefore, it is necessary to design a system that can automatically monitor the fall of ...
