Problems solved by technology

[0004] Although the above-mentioned fall detector 11 increases the reliability of fall detection by integrating the barometer, it is precisely because of the reliability of the barometer that the detection results of this fall detector will be interfered by the weather
Specifically, it is possible for a fall to be missed or a false alarm to occur

Embodiment Construction

[0025] Hereinafter, embodiments of the present invention will be described more specifically with reference to the accompanying drawings.

[0026] figure 2 is a block diagram of the structure of a device 20 for indicating a user's fall by means of an alarm message according to the present invention.

[0027] The device 20 comprises: a receiving unit 21 configured to receive a first alarm message FAM sent by a fall detector 30 to be worn on the user, the first alarm message indicating whether a fall event associated with the user occurs , and indicates that the first alarm message is determined according to the air pressure data detected by the fall detector and the user motion data. will refer to image 3 The generation process of the first alarm message FAM is explained.

[0028] The device 20 also includes an acquisition unit 22 configured to acquire weather data WD, which reflects the weather conditions in the area where the user is located.

[0029] In an embodiment, ...

Abstract

The invention relates to a method and apparatus for indicating a fall of a user by means of an alarm message. According to the invention, the apparatus (20) comprises a unit (21) for receiving a first alarm message (FAM) sent by a fall detector (30) intended to be worn on the user, the first alarm message indicating whether a fall event in association with the user occurs, which first alarm message is determined by air-pressure data and user motion data detected by the fall detector (30); a unit (22) for acquiring weather data reflecting the weather condition of the area where the user is situated; a unit (23) for determining whether or not the first alarm message is reliable, based on said weather data and predetermined criteria; and an output unit (24) for generating and outputting a fall alarm when the first alarm message is determined as being reliable. The apparatus dramatically reduces false alarms by acquiring weather data for determining the reliability of alarm messages generated by the air-pressure sensor.

Description

technical field [0001] The present invention relates to fall detection, in particular to a method and device for indicating a user's fall by means of an alarm message, and to a method and system for fall detection. Background technique [0002] EP 1 642 248 describes a wearable multimodal fall detector that uses both an accelerometer and a barometer to increase the reliability of fall detection, see the disclosure of previously published patent document EP 1 642 248 , which is cited herein as a reference. According to the air pressure measured by the barometer, the height change of the fall detector during the fall can be obtained. If the fall detector is worn on the upper body of the human body, then typically the height of the fall detector will be reduced by at least 50 cm, which can be obtained by a barometer. Such fall detectors can be used in conventional emergency response systems for fall alert messages and aided by third parties. [0003] figure 1 is a schematic...
