Information and communication technology represented by the Internet and mobile communication has changed the life patterns of modern people. Nearly all homes, schools and offices have Internet-enabled personal computers that enable them to acquire information through Web sites, purchase products through e-commerce, and exchange news via e-mail. Also, just a few years ago, people could only use voice communication-oriented mobile communication services using mobile terminals, but recently, only one mobile terminal can be used for financial settlement, home automation, video shooting, photography, It is now possible to receive various services such as listening to MP3 music and using wireless Internet.

As such, the rapidly developing information and communication technology is being applied to various parts of real life, and the new term “Ubiquitous” has emerged. Ubiquitous is a Latin word meaning 'anywhere' and ubiquitous computing refers to an environment where computers can be used naturally and conveniently in life regardless of place or time.

That is, it means that the micro computer device for transmitting data to each other through wireless data communication is embedded in objects and spaces around the real life.

Current ubiquitous technology is implemented based on RFID technology. Radio Frequency Identification (RFID) technology, commonly referred to as smart labeling, is a technology that remotely detects and recognizes information stored in microchips using radio waves, and is commercially used in public transportation toll collection systems and logistics tracking devices.

In recent years, with the rapid development of wireless communication technology, the spread of wireless devices has changed many people's lifestyles. In particular, high-speed broadband wireless communication can coexist with existing wireless communication services without securing additional frequency resources. UWB communication that can be done has been actively studied in recent years.

UWB wireless technology is a communication technology that uses a wide frequency band in a broad sense, and has been studied mainly for military purposes in the United States since the 1950s. Since 1994, military security has been lifted and some venture companies and research institutes have begun developing UWB wireless technology for commercial purposes. Then, on February 14, 2002, the Federal Communications Commission (FCC) allowed commercial use. UWB technology is currently being standardized by the Institute of Electrical and Electronics Engineers (IEEE) 802.15 Working Group (WG). UWB, as defined by the FCC, means a radio transmission technology in which the frequency bandwidth to be used occupies 20% or more of the center frequency, or 500MHz or more.

Here, the bandwidth is determined based on the -10dB point, unlike the other communication based on the -3dB point. In particular, unlike conventional narrowband communications, where a single band UWB carries a baseband signal on a carrier to transmit data, it uses very short baseband pulses of several nanoseconds to transmit data without using a carrier. Therefore, since UWB pulses of several nanoseconds in the time domain have a wide band of several gigabytes in the frequency spectrum, it can be said that the wireless communication technology has a significantly wider frequency bandwidth than the conventional narrowband wireless communication technology.

UWB wireless technology, which transmits data using extremely short pulses of several nanoseconds, has many different features from conventional narrowband communications. Since UWB is basically a signal transmission using pulses, the bandwidth is very wide in the frequency band, and conversely, the transmission power density on the frequency axis is small. In other words, communication is possible even under the noise band.

The reason why UWB wireless communication technology is able to transmit at high speed can be explained by Shannon's capacity. At the Shannon limit, the maximum data rate at which data can be transmitted without errors for both wired and wireless communication systems can be defined as the inherent communication channel capacity C for each given physical communication channel. In particular, the bandwidth B of a frequency that can be transmitted is constantly limited so that the maximum transmission capacity C in a channel where an error occurs due to noise is given by Equation 1.

Equation 1

(Where C stands for maximum channel capacity, B stands for channel bandwidth, S stands for signal power, and N stands for power of noise)

Looking at Equation 1, it can be seen that C increases linearly with respect to B and also increases logarithmically by S / N. In other words, increasing bandwidth means that the maximum channel capacity that can be transmitted on a channel can be proportional to it. Since UWB transmits and receives information using a short wavelet, the bandwidth can be as wide as several GHz when observing the UWB signal in the frequency domain. This means that when UWB communication is carried out, the data transmission is extremely fast. In addition, UWB has the advantage of being able to communicate with relatively low power because it uses a wide bandwidth, and has the advantage of enabling multiple access and suppressing the influence of interference caused by multiple paths.

UWB can be applied in various fields, and one of the areas that attracts a lot of attention is high-speed near field communication in an area of about several tens of meters. The method of modulating UWB signal for high speed local area communication includes pulse position modulation (PPM) using a change in the temporal position of a UWB wavelet, and pulse amplitude modulation (PAM) using a pulse size. ), Phase Shift Keying (PSK) such as BPSK and QPSK, and Orthogonal Frequency Division Modulation (OFDM) are known.

However, the conventional short-range wired and wireless communication and the RFID communication method is used individually, and there are many inconveniences because they are not interlocked with each other. Each communication is performed individually and the user wants to play a role. However, when both methods are required, the communication is not performed.

The present invention has been made to solve the above problems, the user's status and location information stored in the RFID card, the user possesses, read the information of the RFID card through the control unit and the UWB communication module of the communication control display unit It transmits to the server, and displays information such as the current state and location of the user with the LCD and speaker connected to the control unit, and wirelessly communicate the changes or command signal by analyzing the information transmitted wirelessly from the communication control display unit in the server The present invention provides a data control device using RFID and UWB communication transmitted to a control display unit.
