AI Technical Summary

Problems solved by technology

At present, all the data acquired by the sensor is usually transmitted to the CPU in real time, and the CPU processes the data to determine whether a fall has occurred. However, the amount of data transmitted between the sensor and the CPU is large, which may easily cause data loss and misjudgment.

[0038] refer to figure 1 , which is the first embodiment of the fall detection device of the present invention, the fall detection device includes:

[0039] The signal receiving module 100 is used for receiving the weightlessness interruption signal, impact interruption signal and stationary interruption signal sent by the sensor device.

[0040] Wherein, the weightless interrupt signal is triggered by the sensor device according to the detected combined acceleration being less than the preset first acceleration threshold, the impact interrupt signal is triggered by the sensor device according to the detected combined acceleration exceeding the preset second acceleration threshold, and the stationary interrupt signal is triggered by The sensor device is triggered according to the resultant acceleration difference detected twice adjacently being smaller than a preset third acceleration threshold, and the resultant acceleration is obtained by periodic detection by the sensor dev...

Abstract

The invention discloses a falling detection device, comprising a signal receiving module, a primary judgment module and a processing module, wherein the signal receiving module is used for receiving a weightlessness interrupt signal, an impact interrupt signal and a static interrupt signal; the primary judgment module is used for judging whether a falling event occurs according to a sequential order of the received weightlessness interrupt signal, the impact interrupt signal and the static interrupt signal as well as time intervals among the different signals; and the processing module is used for transmitting falling alarm information to a mobile terminal when the primary judgment module judges that the falling event occurs. The invention further discloses a falling detection method. The falling detection device and the falling detection method improve the accuracy of judging the falling event.

Description

technical field [0001] The invention relates to the field of human fall detection, in particular to a fall detection device and method. Background technique [0002] There is a large elderly population in my country, and falls can lead to serious consequences such as fractures, soft tissue injuries, and psychological trauma in the elderly, and are one of the important causes of disability, disability, and death in the elderly. At the same time, the injuries and medical costs caused by the falls of the elderly are not only related to the severity of the impact during the fall, but also largely depend on the length of the rescue response time. Quickly and effectively discovering the occurrence of falls and treating the elderly is an effective means to reduce the casualty rate of the elderly. At present, all the data acquired by the sensor is usually transmitted to the CPU in real time, and the CPU processes the data to determine whether a fall has occurred. However, the amoun...
