Description

{School meal management system using smart box}

The present invention relates to a school meal management system, and more particularly, to a school meal management system using a smart box having an RFID tag embedded therein.

In addition, the school meals management system which promotes the public health by providing sanitary food such as university hospital / hotel / company / land, air force army and so on so that it can be managed in a batch and real time by the convergence technology of IT and BT will be.

In general, the food supplier is the method of checking offline on the basis of the paper documents after the electronic bidding.

And, the food is composed of the steps of production - purchasing - logistics - inspection - preparation (manufacturing) - food (product), and if the final food is defective, it leads directly to food poisoning.

In addition, the term "meals" refers to the provision of meals to students, employees, patients, etc. at schools, factories, hospitals, etc., or to provide a meal for a certain user on a non-profit basis at a certain place outside the home. By feeding nutritionally balanced foods, it is possible to improve the physical and mental development of school meals, to improve the work force of the worker's employees, to prepare food considering the prevention of occupational diseases, to improve the treatment effect of the inpatients, There are various types of group meals, such as hospital meals that provide meals, and military meals to improve the health of soldiers in the land and air.

Here, school meals are a major foodservice type in that they provide a balanced impact on growing children and improve physical fitness, so that the child's mind and body develops and the food that helps improve the community and the national diet is selected. , And the recent school meals rate is almost 100%.

This kind of school meals, unlike the meals in the home, is a large-scale meals with many defects due to problems such as diet, food expenses, time and labor, facilities and facilities, and sanitation problems. There is no change or poor taste. In the summer, if hygiene control and the distribution period of food ingredients are not thoroughly performed, there is a risk of causing food poisoning.

On the other hand, a dietitian should prepare a diet considering the nutrition, economy, cooking, and working side of the most important foodservice management, but the cycle of the diet is not provided with the same food on a given day.

In addition, since one or two dieticians conducts the management of the current meals, not only the setting of the menu of the meal is difficult, but also the cooking process is different according to the school foodservice.

In addition, the nutritional and caloric value of the food is converted to the nutritional and nutritional management of Korean nutrients, which is not scientific and systematic.

In the case of school meals, information on the cultivation and distribution of foodstuffs, food storage and cooking processes is provided by RFID / USN technology to improve the health of students through balanced nutrition and to provide a stable supply of innocuous foodstuffs. It enables to manage in batch and real time, and when supplying foodstuffs such as agricultural products, aquatic products, etc. to consumers, it is possible to check the production history information and raw materials of ingredients by using unique information of electronic tag and food materials attached to food It should be possible to improve the reliability of food ingredients, establish early warning systems for infectious diseases, and promptly manage new infectious diseases.

In the Food Sanitation Act of Korea, HACCP (Hazard Analysis Critical Control Point), which is the "Critical Control Point for Food Hazard Factors", is established. It is a scientific, cost effective and preventive method , And the importance of international trade is emphasized. Therefore, it is expected that Korea will be able to apply this system through the Food Sanitation Act , And it is demanding that developed countries around the world require the same level of safety for food produced in their own country and imported food, and apply the HACCP as an effective means of this.

On the other hand, due to the recent rapid development of information and communication environment, ubiquitous, which is a communication environment capable of connecting to a network regardless of time and place, has been attracting attention. In the information communication field, And various mobile communication devices have been introduced with products that emphasize portability and convenience. They can turn on and off boilers at home by phone or Internet, and control machines at overseas factories at their places. Ubiquitous Means an information technology environment that easily puts a computer into a device or object and facilitates communication with the user.

In addition, RFID (Radio Frequency Identification) that enables information to be exchanged and processed in real time with existing IT systems by recognizing the surrounding situation by attaching RFID tags to objects is emerging as a next generation recognition technology. In the past, it has been widely recognized as a next-generation technology to replace the barcode used for product management in a distribution field. RFID is composed of a reader that reads and decodes data and a tag that provides information so that the tag attached to the product stores information on all processes of production, distribution, storage, and consumption, To read this information, and to integrate it with the information system in connection with satellite or mobile communication network. .

Ubiquitous Sensor Network (USN), which is a network configured to wirelessly collect information sensed by various sensors, is also receiving attention as an infrastructure for achieving ubiquitous computing. (WPAN) technology and ultra-small network device technology, the sensor network technology is very active. In this paper, we propose a wireless sensor network In USA, this technology is applied to home automation, ecological monitoring, etc., and it will be widely used in the fields of social infrastructure safety monitoring, forest fire monitoring, industrial facility monitoring, and defense. Is the reliability of delivering accurate information quickly, Power consumption is also very important, and USN technology, which can be used for several years with one battery, has been developed in Korea.

In the case of school meals, students are encouraged to improve their health by balanced nutrition and to provide information on the cultivation and breeding of food ingredients, logistics delivery, food storage and cooking processes in order to provide a stable supply of innocuous foodstuffs. And to provide food such as livestock, agricultural products, and aquatic products to consumers by using unique DNA information of electronic tags attached to food ingredients and raw materials of ingredients, The need for a system to monitor food ingredients using ubiquitous technology so as to improve the reliability of foodstuffs, establish an early warning system for infectious diseases, and promptly manage and treat new infectious diseases. Is emerging.

However, the present foodservice system has a drawback in that it takes much time to inspect the origin and items of the product, and also can not obtain accurate information of the product, because the method of inspecting the food station on the off-line is based on the paper document prepared by the supplier.

In addition, school meal materials should be distributed in a dedicated container for efficient distribution management, and a system for confirming whether school meal materials are safely transported and processed is being implemented.

That is, the transportation / processing information of the school feeding material is transferred to the system through the electronic tag and the electronic tag reader attached to the discharge exclusive container and managed. In such a conventional system, the RFID tag is attached to the dedicated container, RFID tags are used to identify dedicated containers.

However, since the RFID tag used in the conventional system can recognize only one band, there is a problem in that it is divided into a remote RFID tag or a near-by RFID tag.

4 is an exemplary view of a smart box having an RFID tag embedded therein.

Referring to FIG. 4, one RFID tag is made to respond to both the NFC and UHF bands, so that it is more economical and easier to manage when two tags are used.

That is, the smart box of the present invention is manufactured by inserting an RFID tag having a unique identification number.

At this time, the RFID tag is configured to use both of the two bands including the HF multi-band RF ID tag antenna.

That is, the RFID tag can be configured to simultaneously support the ISO 15693 protocol and the UHF band including the 900 MHz band, and can simultaneously support the UHF band including the ISO 14443A protocol and the 900 MHz band, It may be configured to simultaneously support the ISO 14443A protocol and the ISO 15693 protocol.

In general, ISO 14443 has a communication range of about 10 cm in proximity communication, and ISO 15693 has a communication range of 1 m in peripheral type communication.

Hereinafter, the configuration of the RFID tag used in the present invention will be described in detail.

When a signal of about 1 W is transmitted from the reader / writer using a radio signal of UHF band (860 to 960 MHz) and a response signal is sent back to the reader / writer side when the signal is received from the tag (tag) side, Is read by a reader / writer is known as an RFID (Radio Frequency Identification) system.

The communication distance varies depending on the gain of the tag-side antenna, the operating voltage of the IC (integrated circuit) chip in the tag, and the surrounding environment, but is about 3 m.

An RFID tag is generally composed of an antenna having a thickness of about 10 to 30 μm and an IC chip connected to an antenna feed point. This IC chip is generally equivalently represented by a parallel connection of a resistance Rc (for example, 1200?) And a capacitance Cc (for example, 0.58 pF), and the antenna has a resistance Ra (e.g., 1000?), (La) (for example, 48 nH). When these two elements are connected in parallel, the equivalent circuit is as shown in Fig.

Here, the resonance frequency (f ₀ ) expressed by the following equation (1) where the capacitance Cc and the inductance La resonate is matched. Therefore, when the signal of the resonance frequency is received by the antenna, Power is sufficiently supplied to the IC chip.

[Equation 1]

As a basic antenna used for a tag antenna, for example, a folded dipole antenna having a total length of about 150 mm and a width of about 15 mm as shown in Fig. 6 is used. The gain of this antenna is about 2dBi. This total length is half of the wavelength of f = 953 MHz (about 300 mm) and resonates at that frequency by having a current distribution of? / 2. In this resonance frequency, since the imaginary component (inductance and capacitance component) of the admittance of the folded dipole antenna becomes zero, the inductance portion La is connected in parallel to the folded dipole antenna as in Fig. 6, .

Such a general tag antenna operates only in one band of the HF band or the UHF band. When an article to which an RFID tag is attached is made of metal, if an antenna is bonded to a metal surface, unnecessary high- , A phenomenon that the resonance frequency is shifted or the antenna gain is lowered may occur, and communication with the reader / writer may become impossible.
