Description

Food waste collection device with fingerprint sensor based on information and communication technology and control method thereof

The present invention relates to a food waste collection device having a fingerprint recognition sensor based on information and communication technology and a control method thereof, according to an aspect of the present invention, when a user approaches, user identification information is acquired from a smart tag carried by the user Through the reader, the user automatically receives user identification information and authenticates the user identification information without tagging the RFID reader, and when authentication of the user identification information is completed, an inlet for injecting food waste is automatically When the user does not have a short-range wireless communication means, the food is provided with a fingerprint recognition sensor based on information and communication technology, characterized in that by opening the inlet by identifying the user by recognizing the registered fingerprint through the fingerprint sensor It relates to a waste collection device and a control method thereof.

Food waste generated during the sale and distribution process of restaurants and agricultural and marine products, as well as ordinary households, requires a different treatment method from general waste. Therefore, there is a need to separate food waste from general waste and reduce the amount of food waste generated. Korea is pursuing a pre-reduction policy to reduce food waste.

The food waste collection method currently being implemented nationwide includes a door-to-door collection method using a food waste collection container, a pay-as-you-go system through payment verification, and in the case of a single-family house, the discharger puts the food waste in a special collection container on a designated day of the week When placed in front of the house, the collection methods used by the collection workers at dawn the next day are used.

In the case of apartments such as apartments, integrated collection methods are used by using multiple food waste collection / processing devices. In order to use a food waste collection / processing device operated in a prepaid or postpaid pay-as-you-go system, identification means for identifying a user, for example, RFID, are used. In detail, the user collects / disposes food waste.

When tagging RFID on the RFID reader installed in the device, the input port is opened after user identification. After food waste is established, food waste is moved to the collection box. The food waste collection / processing device transmits user identification information and account information to the food waste management system through a communication network. Subsequently, billing for each user is made.

However, Korea has a food culture that mainly consumes watery food, so the food waste that is discharged also contains a lot of water. For this reason, when the user takes the RFID out of the pocket or the like and tags it, food, garbage, or the like is frequently placed on the hand, clothes, or RFID. Also, in order to take the RFID out of the pocket, a container or bag containing food waste.

When the tow is placed on the food waste collection / processing device, dirt remains in the collection / processing device, and odor is generated in the surroundings.

As a related prior document, Korean Patent Registration No. 10-1401037, Announcement Date 2014. 05. 29. (hereinafter referred to as [Patent Document 1]), disclosed a food waste management system. In [Patent Document 1], the user ID is derived by tagging the user's NFC card or RFID card to open the food waste inlet, and the weight of food waste generated by measuring the weight of food waste thrown into the user A food waste management system that provides billing information by sending it to local government servers along with IDs is being released.

In addition, as related related documents, Korean Registered Patent Publication No. 10-1427138, Announcement Date 2014. 08. 07. (hereinafter referred to as [Patent Document 2]), disclosed food waste collection and weight measurement systems for each region of a single-family house. In the above [Patent Document 2], in the food waste collection and weight measurement system for each region of a single-family house, the food waste container for exclusive use of an RFID tag is attached, an RFID reader and an RFID tag and a local food waste collection container and an RFID reader. By including food waste collection and weighing vehicles equipped with a measurement module and a storage module, it is possible to collect accurate discharge data of food waste emissions by region in a single-family home area, and to address the problem of excessive billing of waste disposal costs by collection service companies. It can be solved, and it is disclosed that it is possible to collect and utilize food waste weight information by region in real time by installing a communication module in the food waste collection and weight measurement vehicle and configuring the server to communicate food waste weight information by region. .

In addition, as related related documents, Korean Registered Patent Publication No. 10-1877385, Announcement Date 2018.07.11 (hereinafter referred to as [Patent Document 3]), discloses a food waste disposal device for apartment houses using an RFID meter. In the above [Patent Document 3], by applying the individual improvement equipment (RFID method) to apartments such as apartments, it is possible to reduce the amount of food waste generated by households, and the cost of food waste disposal is reduced, reducing the amount of food waste discharged. In response to this, it is releasing a device for disposing of food wastes in apartment houses using an RFID metering device that can respond and provide an economical alternative to the metering system.

However, in the [Patent Documents 1] to [Patent Documents 3], food waste can be discharged only by tagging the RFID directly to the RFID reader, so when the user takes the RFID out of the pocket or the like and tags the hand, clothes or RFID, food waste Occasionally. In addition, when a container or bag containing food waste is placed on the food waste collection device in order to take the RFID out of the pocket, the problem that the odor is generated around the collection device is not solved, and it is difficult to discharge without RFID. There was a problem.

The specific structures or functions of the present invention described below are merely exemplified to describe embodiments according to the concept of the present invention, and the embodiments according to the present invention may be implemented in various forms, and the embodiments described herein It should not be construed as being limited to examples.

First, RFID refers to a technology that enables identification of an object such as an object or a person using radio frequency (RF). RFID is used as a method of recognizing information through an RFID reader after storing information in an RFID tag composed of an antenna and a chip and attaching it to an application target.

RFID is used in a similar way to reading a conventional barcode. However, unlike barcodes, data can be recognized without touching the object directly or using any aiming line. In addition, it is possible to recognize or correct multiple information at the same time, and it is possible to recognize information even if there is an obstacle between the tag and the reader.

RFID allows a large amount of data compared to barcodes. Nevertheless, the speed of reading data is very fast and the reliability of data is also high. It is also possible to record data repeatedly depending on the type of RFID tag, and can be used semi-permanently as long as there is no physical damage.

RFID tags can be divided into active type (Active type) that requires power depending on the presence or absence of power supply, and passive type (Passive type) operated by the electromagnetic field of the reader without supplying power directly from inside or outside. The active type has the advantage of reducing the required power of the reader and increasing the recognition distance from the reader. The passive type is very light compared to the active type, and has an advantage that it can be used semi-permanently while being inexpensive.

In the present invention, the active tagging method is called a smart tag, and the passive tagging method is called an RFID tag.
