Description

The refrigerator substance confirmation system uses LCD display and support the Reader}

The present invention relates to a refrigerator contents checking device using an LCD using a reader, and more particularly, a barcode reader or an RFID chip reader to which a unique recognition code is assigned to manage existing refrigerator contents in a home or a store is embedded in a small LCD monitor. Thus, the present invention relates to a system that enables real-time checking of the validity period of contents and the like by a non-contact method of a barcode or an RFID chip.

In general, household refrigerators have a device that can confirm whether the food is damaged or the expiration date due to neglect of the management of the contents, and the cases of discarding or not knowing the expired foods are increasing. In this conventional case, the refrigerator door is frequently opened and closed in order to check the contents of the refrigerator, which causes problems in power consumption.

The present invention was created to solve the above-mentioned problems, and includes a barcode or RFID reader with a unique identification code in the LCD monitor product of the present invention and attaches a barcode or RFID chip to a refrigerator. It reads in a non-contact manner and displays the expiration date and product type on the LCD monitor in real time, effectively reducing the power consumption caused by neglected management of refrigerated products or the wasteful elements that are expired. The purpose is to manage the

In order to achieve the above object, the contents confirmation system of the refrigerator using the reader of the present invention is composed of an input unit, a central processing unit, and an output unit, and the input unit is a barcode reader or RFID reader capable of recognizing information without contact, and a central processing unit. It consists of a central processing unit that separates the product type, expiration date, and current time by reading the information, and a memory device that stores the processed data.The output part is an LCD monitor device that displays the stored information. Including audio device, LED lighting device to inform.

Here, the input unit with the reader may be a barcode.

Alternatively, the input unit with the reader may be an RFID chip.

On the other hand, if the identification code of the reader recorded in the input unit is a barcode may be a predetermined identification code with a unique value, if the identification code is not confirmed by the consumer, automatically separated and input based on the current date and time To be possible.

Alternatively, if the reader's identification code recorded in the input unit is an RFID chip, the identification code may be a predetermined identification code. If the identification code cannot be confirmed by the consumer, the identification code is automatically separated based on the current date and time. Allow input

Meanwhile, the central processing unit may process information through the reader of the input unit in the step of processing the recognition information transmitted from the input unit, but may receive and process the input signal through the LCD touch panel of the output unit to recognize the input signal recognition error. Deleted data can be deleted and initialized.

The input unit may include a function of adding a USB memory data input device to store a picture in a memory device of the central processing unit and then displaying the picture through an LCD monitor of the output unit.

Refrigerator contents confirmation system by the LCD using the reader according to the present invention has the following effects.

First, it is a system that can recognize barcodes or RFIDs with unique identification codes. It is designed to be attached and used for easy attachment to refrigerators in general homes, and it is designed to be convenient for use without opening the doors of refrigerators. It is easy to check the contents of the refrigerator in real time from the outside.

Second, since the contents of the refrigerator can be viewed at a glance, the refrigerator door is not opened frequently, which reduces the power consumption and reduces the waste of the expiration date when the contents of the refrigerator are left for a certain period of time.

 Third, it can be provided to enjoy the picture by mounting the normal electronic picture frame function.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms or words used in the present specification and claims should not be construed as being limited to the common or dictionary meanings, and the inventors should properly explain the concept of terms in order to best explain their own inventions. Based on the principle that it can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical ideas of the present invention, various modifications that can be substituted for them at the time of the present application It should be understood that there may be balances and variations.

As shown in FIGS. 1 and 2, a refrigerator content checking system 100 using an LCD according to an embodiment of the present invention includes an input unit 101, a central processing unit 102, and an output unit 107. do.

The input unit 101 is configured as a reader that recognizes all products with a unique identification code. Here, the reader may read a barcode and may read an RFID chip.

Both barcodes and RFID chips are standards for non-contact tags. Barcodes tend to be cheaper but have shorter recognition distances using light. In addition, RFID has a long recognition distance and can be equipped with a memory to provide various information. However, since an antenna and a memory must be provided, the configuration is complicated and the price tends to be relatively expensive. Is being used.

Meanwhile, the central processing unit 102 processes the identification code received from the reader 101 and processes the information such as product type, expiration date, and production date, which are information recognized from the reader 101, and outputs the output unit 107. ) Is displayed on the LCD 108 screen. The MEMORY 105 is used as a device for storing information and contents read by the reader 101 as a memory device, and the EEPROM 104 is used as a device for storing initial system driving data as a memory device. The D / A CONVERTOR 106 processes the valid period or the current date from the MCU 103 device with respect to the information recognized by the reader 101, automatically generates a predetermined signal after the valid period passes, and then converts it into a voice signal for output. The SPEAKER 109 of the unit 107 generates a predetermined signal to confirm the valid period.

In addition, the output unit 107 is an LCD 108 for displaying the information processed by the central processing unit 102 on the screen, SPEAKER 109 for sounding a voice signal after the valid period, the central processing unit 102 after the valid period Receives a pulse signal from the blinking LED 110 is configured.

On the other hand, the LCD 108 of the output unit 107 is equipped with an LCD PANNEL 111 to delete or modify the information recognized from the reader of the input unit 101 through the MCU 103 of the central processing unit 102 by touch. To help. In addition, the LED 110 of the output unit 107 is configured such that the red LED 110 can be turned on for the product of the validity period of the signal processed by the central processing unit 102.
