摘要
The present invention relates to an apparatus and a method for alerting a guard distance, capable of alerting a guard distance in real time by transmitting and receiving a wireless signal between a portable device and a transmission kit to measure a distance and by outputting an alert sound to an ear microphone to correspond to the distance. In addition, according to the present invention, it is possible to measure a distance based on a wireless signal by setting pairing between a plurality of portable devices and a plurality of transmission kits, and to detect whether a target is separated from a group in real time by sharing distance information, so as to alert a detection result via an alert sound. Also, if a smart band which can be worn on an arm or a wrist and performs a display function is used as a transmission kit, and a portable device is used as a guard distance alert device by installing a guard application in a smartphone, it is possible for a plurality of guards to recognize, in real time, whether a target separated from a group is present among a plurality of targets to be guarded acting as a group for many-to-many guard as well as one-to-one guard, so as to take a measure.
