Description

Liquid crystal nozzle management system using RFID {SYSTEM FOR MANAGING AN EXCLUSIVE LIQUID CRYSTAL NOZZLE USING THE RFID}

The present invention relates to a system for managing a liquid crystal nozzle, and more specifically, liquid crystal nozzle management using RFID that can be managed in association with the device combined with each component constituting the liquid crystal nozzle using the RFID technology. It's about the system.

In general, RFID (Radio Frequency Identification) technology is a technology that obtains information by communication between the terminal and the integrated IC chip (Integrated Circuit Chip) or terminal of the object using radio waves.

The system adopting the RFID technology basically comprises an electronic tag having an IC chip, a reader that reads or writes information therefrom, and an antenna that transmits and receives radio waves between the electronic tag and the reader. It is. The electronic tag is known as a sender and attached to an object to be tracked and stores data related to the object. The electronic tag is classified into an active type and a passive type according to a power source.

Passive tags derive the power needed to transmit the data stored in the tags from radio signals sent by the data readers. Active tags derive their power from the on-board battery. Type tags have a wider area of reading and writing than passive types.

In addition, according to the data memory format, it is divided into read-only format and read-write format. The read-only format tag stores object information in memory when a tag is attached, and once stored information is modified or added. This is not possible, and tags in a read / write format can be changed and stored in memory several times via radio frequency signals.

On the other hand, the interrogator or reader constituting the RFID system has a radio frequency unit that enables communication with the tag using RF energy. This function reads the tag's unique data from the tag in a form that can be carried by hand or fixedly installed. When using a tag that is read / write, the reader can enter new information into the tag. Most readers that make up an RFID system communicate with the host computer using standard communication methods, and can also network with other readers or host computers between one or more facilities.

In addition, the antenna constituting the RFID system is connected to the data collector to send a radio signal or to receive a signal from the tag. The reading range of the antenna associated with the tag depends on the frequency of use and the output used. Some active tags can be read from hundreds of meters from the reader or reader, while passive tags Reading is only possible at relatively close distances of tens of meters. Active tags are applied to various management fields such as mail tracking, transportation supply chain management, inventory management of goods, management of arrangement and arrival and departure of transport vehicles, and access control area management.

For example, an article management system using an RFID tag is disclosed in an article management system (Fine Information Communication Research Institute, Inc.) (Document 1) using an RFID tag of Korean Patent Publication No. 10-0235915. In the system, an RFID tag is arranged for each item location in a store or a warehouse, and the name and unit price of the RFID tag may be displayed on the display panel, and the name of the manufacturer and the number of items handled may be displayed on the display panel. Therefore, the information per item is managed by the host computer by the database server, and if a change in unit price, a quantity change of the item, or a change in the management item occurs, the change data is stored in the database server by the host computer. At the same time, the changed information is transmitted to the corresponding tag in real time and updated to the existing information, so that information management on accurate goods is performed.

On the other hand, the liquid crystal nozzle is composed of a plurality of components, such as a liquid crystal connection bracket, a first connection nozzle, an intermediate connection bracket, a second connection nozzle, a facility connection bracket, as shown in FIG. Therefore, the liquid crystal nozzle is received in each component state upon receipt, and is used in the form of one device by combining them. However, in order for a worker to manage the history or the expiration date for each part, a lot of manual work of a person is required and work efficiency is inferior. In addition, in order to clean the combined liquid crystal nozzles, each component needs to be disassembled and washed again and then recombined. have. In addition, when combining the liquid crystal nozzle with the liquid crystal bottle, it is difficult to know whether or not mutual compatibility, there is a problem that can be incorrectly combined.

Therefore, there is a demand for a method for facilitating and effectively managing the components of the liquid crystal nozzles.
