Ultra-wideband based intelligent indoor positioning system and method {Indor Positioning System and Method Using UWB}

As modern people's interest in health increases, the health care market is growing. However, unlike the market growth, the center's services for actual health checkups have the inconvenience of having to wait a long time to see a doctor for a short period of time. Recently, various products have been released for health checkups, but an IT convergence health management system that integrates online and offline has not been properly established, and hospitals provide customer service to customers in the hospital treatment and treatment process such as reservation, treatment, payment, and medication receipt. We do not provide any customized services.

Comprehensive health examination services at health examination centers provided at general hospitals or university hospitals guide examinees to the relevant examination room according to the established examination order, call each examinee in each examination room according to the order of admission, and follow the order in which the examinee is called. Accordingly, the medical staff diagnoses the examinee's health condition. In order to conduct a health and physical examination or checkup, a test or checkup must be conducted on certain items that need to be measured. For this, there are cases where the examinee of the test or checkup must move directly to the place where measurement is required, and there are many different items. In some cases, you may have to move to a location multiple times.

According to this conventional health examination service system, when there are many examinees receiving comprehensive examinations, the health examination center becomes very crowded, and as a result, the order of examinations is often changed or omitted, resulting in dissatisfaction of the examinees. In particular, if the examinee wanders around the health examination center without being able to find the location of the examination room, the examination time is further delayed, and from the administrator's perspective, it is impossible to determine which examination the examinee has currently completed and which examination should be performed next, so the examinee is systematically The problem is that it cannot be managed.

Indoor location information and the route to be taken are provided to the examinee's personal terminal, but since many examinees visit health check-up centers, etc., a wide frequency band is used to detect the examinee's location, high-speed transmission is possible, and power consumption is reduced. It is desirable to use less wireless transmission technology.

In general, location-based services (LBS: Location Based Service) using GPS (Global Positioning System) technology are provided. However, the GPS receiver may not be able to completely or partially receive GPS satellite signals indoors, such as inside a building, tunnel, or underground parking lot, so there is a problem in that continuous location information cannot be provided. To solve these problems, various methods for indoor positioning are being studied, such as high-sensitivity GPS receivers, pedestrian DR using MEMS (Micro Electro Mechanical System) sensors, and wireless positioning using wireless communication signals. There is.

Indoor wireless positioning can be implemented using wireless communication devices such as Wi-Fi, Bluetooth, and UWB. The advantage of using these devices is that the infrastructure for wireless communication is already established indoors.

Ultra-wideband (UWB) is a wireless communication technology that transmits large amounts of information at low power over a very wide band compared to the existing communication spectrum. It uses a wide frequency band from 3.1 GHz to 10.6 GHz, enabling communication up to 10 m. It guarantees a transmission distance of 1km, which is 10 times longer than Bluetooth's 100m, and can transmit at a speed of 100 to 500 MB per second using a GHz-wide frequency band. In addition, the power consumption is 1/100th of that of mobile phones or wireless LANs, and the cost of commercializing the technology is low, which is a major advantage of UWB.

In particular, UWB pulses used for location information recognition and ranging operate in the frequency range of 6.5 to 8 GHz, and move away from the crowded ISM band (Industry-Science-Medical band) clustered at 2.4 GHz to protect against wireless transmissions occurring outside the spectrum. does not interfere.

Meanwhile, when using GPS outdoors, there is time synchronization between the GPS satellite and the GPS receiver, so the location is calculated using ToA (Time of Arrival). However, because there is no time synchronization between the AP and the terminal for wireless communication for indoor positioning, ToA cannot be used. Additionally, in the case of Wi-Fi, APs are not synchronized, so TDoA (Time Difference of Arrival) cannot be used. Therefore, in this case, the location of the terminal must be calculated by measuring the strength of the signal transmitted from the AP.

There are two ways to calculate the location of a terminal by measuring the signal strength. One is to calculate the location using triangulation by estimating the distance between the AP and the terminal using a signal propagation attenuation model. The other is to estimate location using a database for fingerprints. Among these, a method of calculating location using the fingerprint technique is being widely studied, but this technique has the problem that it takes a lot of time to build a database and it is difficult to build accurate data.

To solve these problems, we propose installing a UWB gateway indoors to detect the examinee's indoor location more accurately than GPS or Wi-Fi.
