Problems solved by technology

[0006] Although it is possible to perform accurate location tracking by densely installing wireless LAN APs used as a basis for location determination, densely installing wireless LAN APs is disadvantageous in terms of cost, installation, and management, so it is accurately determined using RTLS in a wide outdoor space location problem
Another problem with RTLS tag devices is that because RTLS tag devices generally use batteries to supply driving power, the batteries must be charged or replaced periodically

Abstract

Provided, according to the present invention, is an RTLS tag device generating a power through a shock applied to a piezoelectric element and transmitting tag information or an emergency signal to the wireless LAN APs, and a real time location system including an integrated management server receiving the tag information through the wireless LAN APs to extract location information of the RTLS tag device and providing the extracted location information to a client, and transmitting an alarm signal to the client, if it is determined that the emergency signal has been received or the location information deviates from a predetermined scope.

Description

technical field [0001] The present invention relates to an RTLS (Real Time Location System) tag device and an RTLS (Real Time Location System), and more particularly to an RTLS tag device and an RTLS configured to track the position of a moving object. Background technique [0002] RTLS (Real Time Locating System) is a local area location system that allows tracking and identifying the location of objects in real time. Using simple and inexpensive tags or tags attached to objects, readers receive wireless signals from these tags to determine their location through such communication technologies as Wi-Fi, ZigBee, UWB, RFID, and Bluetooth. A real-time location system (RTLS) mainly includes several methods for calculating distance and position from characteristics of wireless signals. For example, RTLS includes an angle of arrival (AOA) method, a time of arrival (TOA) method, a time difference of arrival (TDOA) method, a triangle method, and a received signal strength (RSS) m...
