Description

[0001] The present invention relates to a position tracking system using a LPWA network,

The present invention relates to a position tracking system, and more particularly, to a location tracking system that does not use a mobile communication network of a mobile communication provider such as a conventional CDMA (Code Division Multiple Access) for transmitting / receiving location information of a location- Using the frequency band of the Industry-Science-Medical (ISM) band, there is no additional frequency fee, and the location information transmission and reception with the control center is accomplished by using the intranet, which has already been operated by itself, The LPWA gateway functioning as a base station of the terminal and the LPWA network can be constituted by the low power wide area (LPWA) transmitter / receiver which basically consumes low power, (LPWA) (Low Power Wide Area To a location tracking system using a network.

Low Power Wide Area is one of the wireless communication networks. It is a communication area of less than 100m between Bluetooth and WiFi, And can reduce the power consumption of the communication terminal compared to a conventional Code Division Multiple Access (CDMA) communication network used in the conventional long distance communication, so that the use time of the communication terminal can be greatly increased, and the conventional CDMA transmission / It is possible to provide a low-cost terminal through a low-cost transmission / reception module and reduce the cost of establishing a wireless communication network,

In addition, the low power long distance communication technology (LPWA) basically uses the 900Mhz band which is the license-free frequency (ISM band, Industry-Science_medical band), so that no additional frequency fee is generated, thereby reducing the economic burden on the user .

Recently, as buildings and roads become more complicated and life patterns become faster and more complicated, the outbreak of blindness is increasing. In the case of childbirth, it occurs mainly in a congested space such as a market, an amusement park, an amusement park, a playground, or the like near a house or a parent. In order to prevent the occurrence of childbirth, conventionally, children are usually wearing ribbons or bracelets, etc. that have few children's names, addresses, and contacts. However, there is a risk of losing ribbons and bracelets, You can find children only if you take them. Especially, if you lose the means of storing the information about the child, the young child who does not know his or her address or contact becomes more difficult to find the parent.

In recent years, a position tracking system has been developed to more actively detect and track the position of a person to be tracked, such as an elderly person or a child, and to inform the manager. The conventional position tracking system is used to detect the position of a person (Global Positioning System) of a terminal of a target person, or detects a positional information through short-range wireless transmission / reception of Bluetooth or RFID (Radio Frequency IDentification) of a target terminal, and transmits the detected positional information to CDMA The base station is connected to the base station using a mobile communication network operated by a mobile communication service provider.
