Problems solved by technology

Since this judgment method only selects one indicator of acceleration for judgment, it is relatively easy to cause misjudgment, resulting in false positives
It can be seen that using the alarm system disclosed in this patent application to perform a fall alarm is not only inconvenient to operate, but also causes a large false alarm rate

Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0020] According to the alarm method for detecting a human body fall of the present invention, it is realized by using a smart phone and a wearable watch. Wherein, the smart phone and the wearable watch are equipped with a communication device capable of communicating with each other, such as a Bluetooth device. In addition, there is an acceleration sensor in the smartphone. When carrying such a smart phone, the acceleration sensor therein can be used to detect the motion acceleration of the human body. The wearable watch in the present invention is provided with a height sensor and an acceleration sensor.

Abstract

The invention relates to an alarming method for detecting fall over of a human body. The alarming method is implemented by an intelligent mobile phone and a wearing type watch. When an acceleration sensor in the intelligent mobile phone detects an acceleration meeting a fall over feature, the acceleration is compared with an acceleration value detected by the wearing type watch; if the error is not greater than 10 percent, a fall over accident may be happened; when a height sensor detects that a height change value is greater than a set threshold value, the human body has fallen over; when the wearing type watch detects that an acceleration value obtained after the human body falls over is lower than the set acceleration threshold value, the human body is in a coma state or arms of the human body cannot move; when the height change value detected by the height sensor is greater than a height change threshold value, after a period of time, if the height is still not recovered to a normal value and the detected acceleration value is lower than the acceleration threshold value, a fall over alarm is given. The alarming method disclosed by the invention is convenient to operate and low in false alarm rate and is suitable for the technical field of dangerous alarming.

Description

technical field [0001] The invention relates to an alarm method for detecting a fall of a human body, which is suitable for the technical field of danger alarm. Background technique [0002] With the advent of social aging, the number of elderly people in my country continues to increase. Elderly people are prone to injuries or even death due to falls due to inconvenient activities and fragile bodies. However, when an old man falls, in many cases, there are no family members around, so timely alarm and rescue cannot be obtained. How to detect the health status of the elderly in real time has become the most concerned issue of the younger generation, especially the one-child generation. [0003] In the prior art, the detection of human body falls is mainly carried out through the acceleration sensor and angular velocity sensor worn on the human body. For example, the alarm system disclosed in the Chinese patent CN101702258A is to detect the acceleration information and pose...
