Problems solved by technology

The first category is positioning crutches. This product provides positioning functions. Although this type of product can provide the location of the elderly in time, the disadvantage is that it cannot detect unexpected situations and cannot give an alarm in time when an accident occurs.
The second category is the multifunctional positioning and alarm crutches. This type of product provides positioning and alarm functions. When the elderly feel unwell, they can manually press the alarm switch and send the alarm and positioning information to their family members through the GSM module. The disadvantages are: If the old man faints suddenly or does not have the ability to press the emergency switch when an accident occurs, the alarm function will lose its effect
However, the height position is a relative change. When the elderly are going up and down stairs, or performing jumping activities, the position will also change, which may cause misjudgment.

Embodiment 1

[0032] Embodiment one, normal walking

[0033] When walking normally, the acceleration vector modulus detected by the acceleration sensor will not exceed the pre-threshold Q1, and the pressure sensor is subjected to periodic pressure on the sole of the foot, and its pressure value is greater than the threshold Q2, so it will not automatically alarm.

Embodiment 2

[0034] Embodiment two, fall process

[0035] When the old man falls, the crutches are in the falling state, the real-time acceleration vector modulus exceeds the threshold value Q1, the height change rate exceeds the threshold value Q3, and the plantar pressure detection value tends to zero and is less than the threshold value Q2. At this time, the maximum of the above three processes If the time interval is less than the threshold time T, the fall alarm condition is reached and the automatic alarm function of the module is triggered.

Embodiment 3

[0036] Embodiment 3: The multifunctional crutch falls down

[0037] When only the multi-functional crutch falls down, the real-time acceleration vector modulus exceeds the threshold Q1, and the height change rate exceeds the threshold Q3, but because the old man is still standing or walking, the pressure value detected by the plantar pressure sensor is greater than Q2, so it cannot reach fall alarm condition.

Abstract

The invention provides a fall-down detection, help calling and locating device comprising a multifunctional walking stick and pressure detection insoles. The multifunctional walking stick comprises anacceleration sensor and a height sensor. The pressure detection insoles comprise a pressure sensor. When the acceleration exceeds the first threshold, the height change rate exceeds the second threshold and the pressure is less than the third threshold, whether the maximum time interval of occurrence of the acceleration change, the height change and the pressure change is less than the fourth threshold is detected. If the detection result is yes, the walking stick emits help calling information and locating information. The advantages of the fall-down detection, help calling and locating device are that manual alarming can be performed and alarming can also be automatically triggered in case of falling down, and the result of fall-down detection is judged through the data obtained according to multiple sensors in the alarm automatic trigger process so that the probability false alarm can be greatly reduced. Besides, the device also includes the locating function, the voice function, the radio function, the storage function and multiple other functions so as to enhance the practicality.

Description

technical field [0001] The invention relates to the field of intelligent auxiliary equipment, in particular to a fall detection, help calling and positioning device, which is used for fall detection, calling for help and positioning. Background technique [0002] At present, there are mainly three types of smart crutches on the market. The first category is positioning crutches. This product provides a positioning function. Although this type of product can provide the location of the elderly in time, the disadvantage is that it cannot detect unexpected situations and cannot give an alarm in time when an accident occurs. The second category is the multifunctional positioning and alarm crutches. This type of product provides positioning and alarm functions. When the elderly feel unwell, they can manually press the alarm switch and send the alarm and positioning information to their family members through the GSM module. The disadvantages are: If the old man faints suddenly o...
