Abstract:Aimed at the fall issues of the aged, a wearable pre-impact fall early warning and protection system which consists of an early fall alarm, protection airbags, a remote monitoring platform and a guardian’s smart phone application was developed. When fall happens, the early fall alarm triggerd airbag system, then airbags in belt inflated as soon as possible to reduce the damage to the aged. After the aged fall down, the early fall alarm rang and sent message to guardian for help. Meanwhile, the kinesiology data during falling time was sent to remote monitoring platform for storage, and falling location was showed in the electronic map. Finally, the reliability of this early fall alarm and protection system was verified. The results indecate that this system could detect falls accurately, accomplish a series functions such as early fall warning and alarm, airbag inflation, data transmission and storage and real-time location, which may be beneficial to reduce direct damage and shorten rescue time.
