Abstract

The invention provides a position monitoring system and method based on indoor precise positioning. At least three ultrasonic signal emission units are arranged at indoor fixing positions respectivelyand are used for sending ultrasonic positioning signals respectively. The ultrasonic signal emission units are neither in the same straightline nor at the same circumference. Wearable equipment is used for receiving the ultrasonic positioning signals from the ultrasonic signal emission units separately, calculating distances between the wearable equipment and the ultrasonic signal emission unitsseparately, determiningindoor coordinates of the wearable equipment on the basis of the distances to the ultrasonic signal emission units, and sending the indoor coordinates to a cloud. An intelligentterminal is used for obtaining the indoor coordinates from the cloud, determining the status pattern of the wearable equipment according to time information and the indoor coordinates, and sending analarm instruction when the status pattern is abnormal.

Description

Technical field [0001] The embodiments of the present invention relate to the field of optoelectronic technology, and more specifically, to a position monitoring system and method based on accurate indoor positioning. Background technique [0002] The trend of aging society is becoming more and more obvious. How to provide for the elderly has become an issue of great concern to society. The main ways for the elderly to provide for the elderly are currently nursing homes and community elderly care. The common point is that there are not enough caregivers to monitor the status of the elderly in real time. Wrestling and sudden illness are the biggest threats to the elderly. This patent proposes a method based on ultrasonic accurate positioning to monitor the position of the elderly and learn the habits of the elderly. Once the elderly has a condition, an alarm will be sent to the monitoring terminal Information, inform relevant personnel to check. For example, the smart terminal c...
