Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a line tracer

The present invention relates to a line tracer transportation robot using RFID, and more particularly, to a line tracer transportation robot using RFID, in which a cargo loaded along a designated route is transported using a line tracer in accordance with an operation signal of an RFID card reader in a workshop, And more particularly, to a line tracer transportation robot using RFID for positioning a cargo at a destination.

RFID is a technology that enables identification (IDentification) of objects such as objects or people using radio frequency (RF). RFID stores information in an RFID tag composed of an antenna and a chip, attaches the RFID tag to a target, and then uses the RFID reader as a method of recognizing information.

RFID is used in a similar way to reading conventional barcodes. Unlike bar codes, however, data can be recognized without touching objects directly or using any line of sight. It is also possible to recognize or modify multiple pieces of information at the same time, or to recognize information even when there is an obstacle between the tag and the reader.

RFID allows a larger amount of data than bar codes. However, the speed of reading data is also very fast and the reliability of the data is also high. It is also possible to record data repeatedly according to the type of the RFID tag, and it can be used semi-permanently as long as there is no physical damage.

The RFID system consists of an RFID tag that combines a semiconductor chip with an antenna around it, an RFID reader that is connected to the antenna and an antenna to communicate with the tag, and a host that controls the system and processes the received data.

The RFID system thus configured operates in the following manner. First, the RFID tag composed of chips and antennas is input to the target and then attached to the target. Second, the reader attached to the gate, the counter, and the toll gate transmits a radio signal toward the RFID tag through the antenna. Third, In response, the data stored in the tag is transmitted. Fourth, the antenna that receives the signal from the tag modulates the received data into a digital signal and transmits it to the reader. The reader decrypts the data and transfers it to the host computer.

RFID is already widely used in our everyday lives. The daily traffic card is one of the typical RFID tags, and the high pass of the expressway also uses RFID technology. Books borrowed from libraries, clothes sold at clothing stores, and wines sold at discount stores are also used with RFID tags.

In addition to this, it is used to check the movement, import and export information of products in the distribution / logistics / transportation field to reduce labor costs and to reduce the management cost. It is also used as means for controlling the attendance of employees and controlling access do. It is also used for the purpose of preventing the forgery and falsification of history and management of agricultural products such as Korean beef and ginseng.

RFID allows the computer system to automatically identify things that had to be individually verified through manual work by the employee. Therefore, the processing speed and the error are reduced for the production and management of the product. In addition, it enables easy identification of where the product is located, thus helping to effectively manage inventory and production.

The line tracer is a robot that moves along a white or black line formed on the floor, and is used for an unmanned robot in a factory. The sensor, which is the most important part of the line tracer, can be divided into two parts. A light emitting sensor for emitting light and a light receiving sensor for detecting reflected light. When the light sensor of the line tracer lights up, the light sensor detects the reflected light and can tell which part is white and black. In this way, the sensor senses different paths of color and moves.

As shown in FIG. 9, the present invention relates to an unmanned freight transfer system using an unmanned freight transfer robot, which receives an operation signal through a wireless communication network and, based on the received operation signal, A QR camera for photographing images of a plurality of QR landmarks arranged on a moving route, image processing the image information of the QR landmark image input from the QR camera, An unmanned cargo transfer robot for reading information and correcting the current position data of the transfer robot based on the read position information to establish a work plan of the transfer robot and an operation signal to the unmanned cargo transfer robot through the wireless communication network An unmanned freight transport system including a host terminal for transmitting a user's freight transport instruction .

However, the QR camera system is more economical than the RFID card system. In general, rather than the line tracer system, the positioning process is complicated and it may be difficult to move to the exact destination.
