RTLS IoT RTLS AND IoT BASED SMART MULTI-TAG AND SAFETY MANAGEMENT SYSTEM USING THE SAME

摘要

A smart multi-tag device to which spatial awareness location tracking technology is applied is provided. This includes a GPS module, a wireless communication unit capable of wireless communication with receivers, an altitude sensor unit, an alarm unit, a storage unit, a power supply unit and a device control unit. The wireless communication unit includes a LoRa communication module, a Zigbee communication module, and an LF communication module. For such a tag device, location tracking is performed outdoors using GPS coordinates, and spatial recognition location tracking is performed indoors using an altitude sensor. In addition, in the safety management system, the same tag device can be placed on the operator, the device, and the danger area, and the distance can be calculated through the strength of the mutual communication frequency to give an alert.
