Description

A human fall detection and alarm device

technical field

The utility model relates to the technical field of human body fall detection and alarm, in particular to a human body fall detection and alarm device.

Background technique

The gradual aging of the population around the world today has made the entire international community pay more and more attention to the issue of aging. According to the report of the National Safety Council of the United States, among the population over the age of 65, the death caused by falls ranks first among all accidental deaths, accounting for 33% of accidental deaths in this age group. If the fall of the elderly can be detected accurately and timely, the cause of the fall can be understood in time and corresponding rescue measures can be adopted to reduce the casualties caused by the fall. However, there are almost no such instruments on the market for monitoring the state of human falls. Even if they have appeared in text or voice reports, most of them only stay in the stage of simple theoretical research or experimental research, and only detect the inclination angle of the human body. Determine the state of the human body. This has great limitations to the true detection of the real state, and only has the function of judging the fall, so for the user, there is a high possibility of misjudgment and false alarm, and it is very passive to use.

Contents of the invention

The purpose of the utility model is mainly to provide a human body fall detection and alarm device to solve the above technical problems.

The utility model includes a main control module, a group of body posture monitoring components and an alarm module. The main control module includes a housing, a main control chip, an analog input module and a switch output module. The main control chip, analog input The module and the switch value output module are respectively fixedly installed in the housing, and the housing is fixed on the torso of the human body through a strap. The body posture monitoring component includes an inclination sensor, a zigbee wireless transmission module and a flexible material jacket. The inclination sensor, zigbee The wireless transmission module is sewn in the flexible material jacket, the inclination sensor is connected to the zigbee wireless transmission module, and the zigbee wireless transmission module is connected to the main control chip through the analog input module. The tape is glued to the limbs of the human body, the alarm module is an audible and visual alarm, and the main control chip controls the opening and closing of the audible and visual alarm through the switch value output module.

There is also a power module, which is composed of a battery pack for powering the main control module and a group of button batteries for powering a group of body posture monitoring components.

The main control module is also provided with a main switch, and the main switch controls the power on and off of the main control module.

The alarm module also has a remote alarm module based on GSM wireless communication, and the main control chip is connected with the remote mobile terminal through the remote alarm module of GSM wireless communication.

The advantages of the utility model are: the utility model has a reasonable structural design, is easy to wear, can effectively detect whether the wearer is in a falling state, and sends out sound and light alarms, and at the same time remotely alarms the set mobile phone, which has good practical value.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, the utility model includes a main control module, a group of body posture monitoring components and an alarm module, and the main control module includes a housing 1, a main control chip 2, an analog input module 3 and a switch output module 4 , the main control chip 2, the analog input module 3 and the switch output module 4 are respectively fixedly installed in the housing 1, and the housing 1 is fixed on the human trunk through a belt, and the body posture monitoring component includes an inclination sensor 5. The zigbee wireless transmission module 6 and the flexible material jacket 7, the inclination sensor 5 and the zigbee wireless transmission module 6 are sewn in the flexible material jacket 7, the inclination sensor 5 communicates with the zigbee wireless transmission module 6, and the zigbee wireless transmission module 6 The analog quantity input module 3 is connected to the main control chip 2 through wireless communication, and the body posture monitoring components of the group are respectively glued to the limbs of the human body through magic tapes. The alarm module is a sound and light alarm 8, and the main control chip 2 The on and off of the sound and light alarm 8 is controlled by the switch output module 4 .

There is also a power module, which is composed of a battery pack for powering the main control module and a group of button batteries for powering a group of body posture monitoring components.

The main control module is also provided with a main switch 9, and the main switch 9 controls the power on and off of the main control module.

The alarm module also has a remote alarm module based on GSM wireless communication, and the main control chip 2 is connected to the remote mobile terminal through the remote alarm module of GSM wireless communication.

Working method and principle: When in use, firstly wear the main control module on the torso of the human body, fix a group of body posture monitoring components on the limbs of the human body in the form of Velcro or straps, turn on the main switch 9, and the device That is to say, it starts to work. When the wearer falls down, the inclination values detected by a group of inclination sensors 5 of a group of body posture monitoring components are all greater than the set threshold. At this time, the main control chip 2 determines that the wearer is in a fall state. The main control chip 2 controls the acousto-optic alarm 8 to alarm through the switch value output module 4, and sends alarm information to the remote mobile terminal through the remote alarm module of GSM wireless communication.
