Abstract

The invention belongs to the technical field of personal safety monitoring, and particularly relates to a locatable wearing type tumbling monitoring system. The system comprises a ZigBee network, a GSM / GPS network, an upper computer and software of the upper computer. An acceleration sensor and a GSM / GPS positioning and communicating device are carried by a subject. A positioning device carries out positioning through the GPS, position information is sent to the upper computer in real time through the GPRS, the sensor measures triaxial acceleration information, the triaxial acceleration information is sent to the upper computer through the ZigBee network to be processed, the upper computer software analyzes the acceleration information, and whether the subject tumbles or not is judged according to the corresponding algorithm, wherein if the subject tumbles, the upper computer can warn and send a short message to an assigned contact person to give an alarm, and after the alarm short message is received, a specific short message can be sent to an assigned number to obtain the current position information of the subject person.

Description

technical field [0001] The invention belongs to the technical field of life safety monitoring, and in particular relates to a wearable monitoring system for monitoring human falls and locating and alarming. Background technique [0002] With the advancement of modern information technology, especially the development of wireless communication technology and low-power microelectronics technology, it is possible to carry monitoring equipment. The feature of low power consumption enables the monitoring equipment to monitor for a long time, and the wireless communication technology enables the monitoring equipment to be used in a long-distance range. The monitoring system made by the present invention is a fall monitoring system based on GSM, GPS and ZigBee technology. The person under test carries sensors, positioning and communication devices with him. The positioning device locates through GPS and sends the position information to On the upper computer, the sensor measures t...
