The present invention is a protection target monitoring system using ultra-wideband wireless communication technology and a protection target monitoring method using the same. However, it provides a system and method for monitoring the subject of protection based on this.

Ultra-Wide Band (UWB) is a wireless communication technology that transmits large-capacity information with low power over a very wide band compared to conventional spectrum.

This technology is a wireless technology applied to communication or radar by using a very wide frequency band of several GHz or more in the baseband without using an RF carrier. It is a wireless communication technology that can be used without interference in the existing communication system by using power density.

Because UWB uses a high bandwidth (500 MHz) and pulses are nanoseconds, high precision can be achieved. Unlike existing narrow-bandwidth Wi-Fi or Bluetooth, the position and angle of the transceiver can be accurately known.

As examples of short-distance wireless communication technologies, representative technologies such as RF-ID, beacon, and Wi-Fi may be mentioned. A beacon corresponding to a location-based communication technology is a wireless communication device capable of automatically recognizing a smart device in a short distance and transmitting necessary data.

Whereas NFC, a short-range wireless communication, only works within a short distance of less than 10 cm, beacons can operate at a distance of up to 50 m. Using beacon technology, data such as discount coupons or detailed descriptions can be transmitted to the smartphones of customers who have visited shopping centers, restaurants, museums, art galleries, movie theaters, baseball fields, etc. However, with these technologies, an error in the range of 1 m occurs in the accuracy of the distance, and it is difficult to determine the exact location because the angle information is not known.

On the other hand, technology for managing children's safety using near-distance technology and Internet of Things technology is being developed. Korean Patent Publication No. 10-2020-0068090 is an Internet-based integrated safety management support system for children's school vehicles. sensors are installed to automatically detect and respond to dangerous situations that may occur in the entire process before, during, and after driving of the vehicle, which provides a support system based on RFID tags.

The prior literature is based on RF-ID or beacon corresponding to existing short-range wireless communication, and is a technology fundamentally different from ultra-wideband wireless communication technology in terms of accuracy of location and data pulse interval.

On the other hand, if UWB technology is used, the distance error of the transmitter can be reduced to within 10 cm, and the angle can be secured within a range of 3 degrees, so the position of the person to be protected can be accurately identified compared to the existing technology.
