Abstract

An RFID reading device is provided. An object and an IC tag attached to the object are disposed in interior space enclosed by a vehicle body made of a material that inhibits transmission of radio waves. An RFID reading device includes an information reading unit and a rotation driving unit. The information reading unit has an antenna unit and receives object-related information through the antenna unit, thereby reading the object-related information. Since the antenna unit is rotated about a predetermined rotation axial line by the rotation driving unit, regardless of the orientation of the posture of the IC tag disposed in the interior space of the vehicle body, the object-related information from the IC tag can be reliably read by reducing the effects of reflection, absorption, and so on of radio waves as much as possible.

Description

technical field [0001] The present invention relates to an RFID reading device and an information reading method using the same, which can be installed in a structure that is difficult to transmit radio waves by using radio frequency identification (Radio Frequency IDentification: RFID for short) technology. It is advantageously implemented by reading information from an IC tag of an object inside the structure or in a radio wave shielding space covered by the structure. Background technique [0002] In the past, in order to manage the information of various components represented by electrical / electronic components and mechanical components and the equipment equipped with the components in real time, the RFID (Radio Frequency IDentification) system has been used. The IC tag is mounted on the above-mentioned components or equipment, and information is transmitted and received by short-distance wireless communication using radio waves between the IC tag and the RFID reading d...
