ADDRESS-BASED SOCIAL SAFETY NETWORK SYSTEM OF SMART GRID INFRASTRUCTURE DEVICE AND METHOD FOR PROVIDING SAME

摘要

The present invention provides an address-based social safety network system of a smart grid infrastructure device, the address-based social safety network system comprising: a portable location information terminal for transmitting an emergency signal through an RF modem when an emergency signal generation command is inputted; a digital energy meter which calculates an average value of wireless reception strength of the emergency signal received from the portable location information terminal and then transmits the calculated average value to an upper end; a collection device which collects the emergency signal received from the digital energy meter, and which transmits the collected emergency signal to the upper end; and a positioning server which collects the emergency signal received from the collection device, and which tracks location information of the portable location information terminal by using the wireless receiving sensitivity and an intrinsic identification address of the digital energy meter.
