Description

{Method for distributing fresh product with IOT base and big data algorithm analysis technique}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of circulating fresh products, and more particularly, to a technique of clearly grasping a current state of a fresh product by monitoring various environmental conditions such as a temperature during a fresh product transportation in real time.

Generally, the food distribution process consists of a process in which a producer produces food, a consumer distributes the food through a distributor, and then a consumer purchases necessary food.

In the food distribution process, the foodstuffs to be distributed must be delivered fresh and stable. In the case of processed and natural foodstuffs, orders ordered by the consumer are returned by about 15% to 25% of the order quantity, The cost is also wasted as much as the sum of domestic and export quantities in the whole country (Korea Consumer Agency: saving 2,200 billion won a year in 5% reduction of processed food waste).

In addition, since the consumer can not maintain the freshness of the ordered food, the dispute between the producers, the distributors and the consumers has not ceased. In consideration of the waste of social expenses due to the environmental pollution of food waste disposal and the national food economy, Improvement of distribution management system is needed.

Since the distribution process of food takes several steps, the distribution time is prolonged, and in this process, due to the nature of the food, it may be altered by factors such as temperature. Accordingly, techniques for distributing food in a fresh state are being attempted.

These techniques are being tried in various forms, an example of which is shown in Patent Application No. 10-2013-54125 (titled: Individual Cargo Monitoring Method in a Container).

This prior art can be provided with tag information for the individual cargo loaded using the relay device mounted on the container and can be used for security and position tracking of the individual cargo loaded in the container until the container reaches the destination Can be managed. At this time, the information reported in the container is the unique adherence, temperature, and humidity.

However, in the related art, the related information is transmitted by attaching a wireless tag such as a temperature sensor and a wireless sensor tag to the container. Such a sensor is mounted on the container to transmit temperature information about the entire space inside the container It is difficult to grasp the individual temperature information for each cargo loaded in the container.

In particular, each cargo loaded in a container is various kinds such as foods and industrial products, and the temperature standards required for freshness are different for each type of food such as fish, vegetables, and fruits.

Therefore, it is possible to monitor the internal temperature of the whole container when sensing temperature information of the entire inner space of the container as in the prior art, but it is difficult to identify the temperature of each container, There is a problem in grasping the responsible place.

In other words, if the temperature inside the container is about 20 degrees and the temperature is suitable for fruits and so on, but the temperature may not be suitable for the fish, the carrier claims that it is not responsible for maintaining the temperature of 20 degrees. You can ask for responsibility by claiming.

Further, in order to solve such a problem, there is a problem that it is difficult to collect the sensor and the tag when the temperature sensor and the wireless tag are integrally mounted on the package case of each cargo.

That is, the reason for the difficulty in recovering is that the temperature sensor and the tag are disposed inside the packaging container. Once the container is opened and the consumer opens the packaging container and collects the sensor and the tag, It is difficult.

Most of the time, when the consumer is absent, it is delivered to the security room or storage box, and the sender can not arbitrarily damage the packaging container.

In this case, since the packaging container of the cargo is difficult to be recovered again after the transportation, the sensor and the tag attached to the packaging container are often discarded as they are. In this case, the manufacturing cost of the sensor and the tag increases the logistics cost .

In addition, there is a problem in that producers and distribution distributors are damaged due to information disseminated without clear reason through the SNS regarding satisfaction / dissatisfaction with the products received by the consumers in the food distribution process.

Patent Application No. 10-2013-54125 (Name: Individual Cargo Monitoring Method in Container)

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to improve the temperature sensor and the tag in a detachable manner so that a temperature sensor is disposed inside the packaging container, When the cargo is delivered to the cargo container, only the outer tag is collected and the inner temperature sensor is discarded, thereby increasing the collection rate of the tag, thereby reducing the logistics cost.

In addition, SNS information on consumers' complaints is developed and applied to the Big Data algorithm analysis technique to prevent the waste of the national budget by reducing the national food safety cost caused by the food waste of the producer / distributor .

In order to accomplish the above object, an embodiment of the present invention provides a method of distributing a fresh product,

A third step (S120) of measuring the temperature and humidity in the packaging container (2) and storing the current position data in the wireless sensor tag (7);

A fourth step S130 of the wireless sensor tag 7 transmitting the measured data to the reader 8;

The reader 8 transmits the data to the management host 6 through the communication unit 10 in a fifth step S140;

A sixth step (S150) of presenting the temperature data of the goods to the consumer (C); And

And a seventh step (S160) of analyzing the measured temperature data by an analysis algorithm of the big data and calculating an appropriate temperature for each product.

The method for circulating a fresh product according to an embodiment of the present invention has the following advantages.

First, by improving the temperature sensor and the wireless sensor tag into a separate structure, the temperature sensor can be disposed inside the packaging container of the food, and the wireless sensor tag can be disposed outside, so that the temperature sensor at the time of delivery leaves the wireless sensor tag It is possible to recover the wireless sensor tag even in the absence of the consumer, thereby reducing the logistics cost.

Second, an ON signal is generated and transmitted to the management host when one pin among a plurality of pins formed at the terminal of the temperature sensor and one pin groove of the plurality of pin grooves formed at the port of the wireless sensor tag are coupled to each other The management host has the advantage of accurately monitoring the start of delivery of the food and monitoring it.

Third, IOT element technology and Big Data algorithm analysis method of food distribution analyze consumers' tendency / trends to understand consumer tendency and emotion index, and send the result to producers, so that advanced scientific food distribution management system And this information enables the producer / distributor to improve the complaints of consumers by reflecting the system of processing, distribution and delivery of food to the production line and distribution / delivery line.

Fourth, it monitors the whole process of food distribution including information about temperature and quality of real-time food, operation information of delivery / transportation vehicles, maintains fresh food system, and conveys information on temperature and humidity of food distribution process to consumers. And can contribute to economic development by preventing waste of national budget caused by food waste.

The present invention relates to a system and a method for transporting a product in a fresh state by grasping the temperature, humidity, etc. of the product in real time, and the object product includes not only food but also cosmetics, vaccines, , Hereinafter referred to as food.

As shown in FIGS. 1 to 5, a method of distributing a product proposed by the present invention includes a first step S100 of attaching a detachable sensor 3 to a wireless sensor tag 7 and attaching the detachable sensor 3 to a food container; A second step S110 of transmitting an ON signal to the management host when the terminal of the removable sensor 3 is coupled to the port of the wireless sensor tag 7; A third step (S120) of measuring the temperature and humidity in the packaging container (2) and storing the current position data in the wireless sensor tag (7); A fourth step S130 of the wireless sensor tag 7 transmitting the measured data to the reader 8; The reader 8 transmits the data to the management host 6 through the communication unit 10 in a fifth step S140; A sixth step (S150) of presenting the temperature data of the goods to the consumer (C); And a seventh step (S160) of analyzing the measured temperature data by an analysis algorithm of the big data and calculating an appropriate temperature for each product.

Such a fresh product distribution method is performed by a product distribution system, and will be described in detail as follows.

That is, the fresh product distribution system comprises a detachable sensor 3 for measuring the internal temperature of the food packaging container 2 loaded on the container of the vehicle 1 and outputting the measured value; A wireless sensor tag (7) detachably coupled to the detachable sensor (3) and storing and outputting measurement data input from the detachable sensor (3); A reader (8) for reading the information of the wireless sensor tag (7) and outputting the result; A communication unit (10) for reading information of the wireless sensor tag (7) and transmitting the information through a network; And a management host 6 that receives information transmitted from the communication unit 10 and grasps the current status of the fresh product in real time.

In this fresh product distribution management system, the detachable sensor 3 is equipped with a temperature sensor or a humidity sensor on one side and a terminal 11 coupled to the wireless sensor tag 7 on the other side.

The temperature sensor 9 includes various types of sensors such as a thermistor and is disposed inside the packaging container 2. [ Therefore, it is possible to measure the inner temperature of the container in which the fresh food is packaged.

A plurality of pins 12 protrude from the terminal 11 and are coupled to a port 13 of a wireless sensor tag 7 to be described later.

The plurality of pins 12 may be variously arranged according to the standard. For example, protocols such as RS422, RS485, LAN, LIN, CAN and LVDS are used. RX) 2-pin or the like. At this time, by assigning one of the pins 12 to transmit the On signal when the terminal 11 of the temperature sensor 9 is coupled to the port 13 of the wireless sensor tag 7 It can be recognized that the temperature sensor 9 and the wireless sensor tag 7 are coupled to the packaging container 2 at the start of delivery at the management host 6. [

Accordingly, the wireless sensor tag 7 can obtain temperature data by transmitting / receiving signals to / from the temperature sensor 9 through the plurality of pins 12. [

The humidity sensor includes a method using a change in electric resistance or capacitance caused by the absorption of moisture by porous ceramics or a polymer membrane, a method using a change in the resonance frequency of the vibrator due to a change in the weight of the absorbing material provided on the vibrator . Such a humidity sensor can also be disposed inside the packaging container 2 to measure the humidity.

The humidity sensor may be provided integrally with the temperature sensor 9 or may be installed separately. Or only the temperature sensor 9 may be mounted on the packaging container 2. [

The temperature sensor 9 or the humidity sensor is detachably connected to the wireless sensor tag 7 to transmit the measured temperature and humidity data.

The wireless sensor tag 7 comprises a substrate 15; A port (13) disposed on one side of the substrate (15) and to which the terminal (11) of the detachable sensor (3) is detachably coupled; An RF transceiver 21 for outputting temperature and humidity data input through the port 13; A memory (19) for storing temperature and humidity data; An analog block 22; A digital block 24; And a power supply unit 26.

The wireless sensor tag 7 having such a structure uses a wireless communication method, for example, an RFID method can be used. In addition, the wireless sensor tag 7 is divided into a place and an application for each frequency band.

For example, the UHF system uses frequencies of 433, 9100 MHz, and microwave 2.45 GHz, and the data transmission / reception distance between the reader and the RFID tag is within the range of 5 m to 10 m. 430MHz is mainly used for active tags, and 910MHz is used for passive tags. This UHF method is mainly applied to the logistics system due to the long data reading distance.

The HF method uses a frequency of 13.56 Mhz, and the data transmission / reception distance between the reader and the RFID tag is within a range of 1 cm to 3 cm. These HF methods are mainly used for traffic cards and credit cards for security and safety reasons.

The dual tag method is a method of simultaneously applying the UHF tag and the HF tag. That is, since the UHF scheme and the HF scheme are different in use and performance as described above, the tags of the two schemes are arranged in parallel and used. For example, the UHF method is used for logistics and the HF method is used for product-specific information recognition.

The LF method (Low Frequency) uses a frequency of 123 kHz.

A plurality of pins 14 are formed in the port 13 and a plurality of pins 12 protruding from the terminal 11 are coupled to the pin groove 14 so that data can be transmitted and received from the temperature and humidity sensors. have.

The ports 13 may be variously arranged according to the standard as in the case of the terminal 11. For example, protocols such as RS422, RS485, LAN, LIN, CAN, and LVDS are used. A transmit (TX) 2-pin groove, a receive (RX) 2-pin groove, and the like.

At this time, by assigning one of the plurality of pin grooves 14 to transmit the ON signal when the terminal 11 of the temperature sensor 9 is coupled, the management host 6 can control the packaging container 2 that the temperature sensor 9 and the wireless sensor tag 7 are coupled to each other.

The analog block A includes a voltage multiplier for generating driving power of the wireless sensor tag 7 by a radio frequency signal applied from the antenna, a voltage limiter for limiting the magnitude of the voltage and outputting it to the click generation unit, A modulator for modulating the response signal applied from the block and transmitting the modulated response signal to the antenna, and a demodulator for detecting an operation command signal from the frequency signal applied from the antenna and outputting the command signal to the digital block.

The digital block D receives a power supply voltage, a reset signal, a clock, and a command signal from the analog block A, analyzes the signal, generates a control signal and a processing signal, and outputs a response signal to the analog block. Further, it outputs the address (Addres), the input and output of the temperature and humidity data, and the control signal to the memory 19.

This digital block D stores or retrieves data in the memory 19. [

The memory 19 automatically stores data input from the temperature sensor 9 or the humidity sensor. For example, the memory 19 may be a memory such as a USER memory in which user data is stored, a TID memory in which manufacturing information of the tag is stored, an EPC memory in which information of the tag is stored, And a reserved memory in which a password is stored.

On the other hand, the reader 8 reads data such as temperature and humidity stored in the wireless sensor tag 7, and then transmits the data to the management host 6 via the communication unit 10.

The reader 8 is mounted on the goods transporting vehicle 1 and can be used separately from the vehicle 1 when necessary.

The reader 8 normally supports three modes, and supports a single reader mode, a multi reader mode, and a dense reader mode.

The reader 8 has a general structure, namely, an input unit 23, a processor core and a controller 27, a memory 29, an output unit 25, a system bus, And a printer (printer) 31 for outputting data to the paper, and reads data stored in the wireless sensor tag 7 by applying various frequency bands.

The reader 8 receives data of the wireless sensor tag 7 located within the recognition range through the antenna and performs a function of reading the data. Then, the read data is transferred to the management host 6. Alternatively, the data may be transmitted to a user-carried cradle.

On the other hand, the food can also be delivered to the distribution center T, and the gate G is disposed at the entrance of the distribution center T to detect the entry / exit of the food transportation vehicle 1.

Such a gate G is installed in a dock of a distribution center T or the like and has various types of gates G such as a portal type or a tunnel type. The gate G is equipped with an antenna, a check reader, and a controller.

Therefore, when the fresh merchandise transport vehicle 1 enters the gate G, the gate G recognizes the vehicle 1 by the check reader of the gate G. [ At this time, the recognized information includes the type of the vehicle 1, the date and time of entering and leaving the vehicle, and the like.

The input information is transmitted to the management host 6 through the check reader so that the management host 6 can grasp in real time that the vehicle 1 arrived or departed to the distribution center T. [

On the other hand, the management host 6 is connected to the communication unit 10 and the gate G via a network such as the Internet. At this time, the network includes a wired and wireless network, and includes a serial interface, an Ethernet interface, and the like.

Therefore, information such as the temperature, humidity and current position of the fresh food transferred from the reader 8 can be input to the management host 6. [

The management host 6 preferably includes a data base, a web server (Wep server), an APP host, and a local computer.

The database stores information such as the temperature and humidity of the fresh food.

The web server is a server for providing a web page (HTML file), and a web server program capable of providing a web page is installed. Therefore, users of the producer P or the like connected to the management host 6 can easily confirm necessary information through the homepage.

Also, the APP host (Application Server) is a server for building an application program. That is, the server stores the application program for processing the temperature and humidity data of the fresh food over time.

Accordingly, the manager can access the management host 6 through the local computer, and can perform processes such as history management of temperature or humidity of fresh foods, system management, data transmission / reception, and the like.

In particular, it is possible to grasp in real time whether the current state of the fresh food is normal by comparing the temperature or humidity value of the fresh food sent from the wireless sensor tag 7 with the reference value.

The management host 6 is connected to the fresh food delivery vehicle 1, the user's computer system, and the management system of the distribution center T via the network.

Therefore, the temperature or humidity information of the fresh food sent by the reader 8 and the communication unit 10 of the fresh food conveying vehicle 1 can be shared with the management host 6 and the user via the network.

That is, the fresh food distributor can determine the current position of the fresh food conveying vehicle 1, the departure and arrival of the distribution center T, the temperature or humidity of each fresh food stored in the container, .

The management host 6 can transmit or receive temperature or humidity information to a portable terminal such as a smart phone through an access point (AP).

In addition, an individual user can access the management host 6 through a network by a personal computer. Therefore, the current position, temperature, and humidity information of the ordered fresh food can be confirmed in real time on the homepage.

Hereinafter, a method for managing distribution of fresh food according to an embodiment of the present invention will be described in detail.

As shown in the figure, the method for managing the distribution of fresh products proposed by the present invention includes a first step (S100) of attaching the detachable sensor (3) to a wireless sensor tag (7) A second step S110 of transmitting an ON signal to the management host when the terminal of the removable sensor 3 is coupled to the port of the wireless sensor tag 7; A third step (S120) of measuring the temperature and humidity in the packaging container (2) and storing the current position data in the wireless sensor tag (7); A fourth step S130 of the wireless sensor tag 7 transmitting the measured data to the reader 8; The reader 8 transmits the data to the management host 6 through the communication unit 10 in a fifth step S140; A sixth step (S150) of presenting the temperature data of the goods to the consumer (C); And a seventh step (S160) of analyzing the measured temperature data by an analysis algorithm of the big data and calculating an appropriate temperature for each product.

In the method for managing the distribution of fresh foods, in the first step (S100), the detachable sensor (3) and the wireless sensor tag (7) are attached to a container packed with fresh food. That is, the terminal 11 attached to one end of the temperature sensor 9 is connected to the port 13 of the wireless sensor tag 7 and the temperature sensor 9 is disposed inside the packaging container 2.

Thus, the temperature sensor 9 measures the internal temperature of the packaging container 2, and the measured temperature is transmitted to the wireless sensor tag 7. [

At this time, both the temperature sensor 9 and the wireless sensor tag 7 may be mounted inside the packaging container 2, or only the temperature sensor 9 may be mounted inside the packaging container 2.

A plurality of pins 12 protruding from the terminal 11 of the detachable sensor 3 are coupled to the plurality of pin grooves 14 formed in the port 13 of the wireless sensor tag 7 in the second step S110 A signal is transmitted to the management host 6 by the combination of the pin 12 and the pin groove 14 which are set to transmit an On signal. Therefore, the management host 6 can recognize that the temperature sensor 9 inside the packaging container 2 is connected to the wireless sensor tag 7 outside the packaging container 2, and from this point on, Management.

In the third step S120, the temperature data transmitted from the temperature sensor 9 is stored in the memory 19 of the wireless sensor tag 7. Various kinds of information are stored in the memory 19. For example, various kinds of information such as a type of fresh product, an order date, an orderer, a shipping date, a fresh product producing place, an appropriate temperature, Can be stored.

Then, in the fourth step S130, the data stored in the wireless sensor tag 7 is transmitted to the reader 8. That is, the data stored in the memory 19 of the wireless sensor tag 7 is transmitted to the reader 8 through the transceiver 21 and the antenna.

At this time, the wireless sensor tag 7 may periodically transmit data to the reader 8, but the reader 8 may receive the stored data by transmitting a signal to the wireless sensor tag 7. That is, data can be transmitted and received in both directions.

In the fifth step S140, the temperature data received by the reader 8 is transmitted to the management host 6 via the communication unit 10 mounted on the transportation vehicle 1.

That is, the fresh food transportation vehicle 1 is equipped with a repeater such as a router, and the repeater outputs the data transmitted from the reader 8 to the management host 6.

The management host 6 can analyze the received temperature, humidity, and current position data through the Big Data Analysis Algorithm technique, so that the temperature and humidity history of the fresh food can be grasped in real time.

Then, the analyzed data is transmitted to the reader 8 so that the fresh food carrier can present the data to the consumer C.

In the sixth step S150, the fresh food is delivered to the consumer C, and data such as the temperature of the fresh food is presented to prove that the fresh food is transported in an appropriate state.

At this time, the carrier can display the corresponding data through the screen of the reader 8, or output it through the printer and display it in paper form.

Consumer (C) confirms this data to confirm that the fresh food has been transported under appropriate temperature and humidity conditions.

Of course, the consumer C may access the corresponding home page and check the current status of the fresh product being delivered before the fresh food arrives.

In the seventh step S160, the measured temperature data is accumulated, the accumulated data is analyzed by an analysis algorithm of the big data to calculate an appropriate temperature for each fresh food, and a message communicating on the Internet is fed back, It is possible to improve the distribution system.

More specifically, the analysis process includes an eighth step (S170) of extracting data such as temperature and humidity obtained each time fresh goods are transported; A ninth step (S180) of extracting data on the actual state of the delivered fresh product; (S190) of combining the data extracted in the eighth step (S170) and the ninth step (S180) and searching for and extracting a message on-line to calculate the most suitable transportation pattern for each fresh product.

In the eighth step (S170), the data inputted when the consumer C orders the fresh food, that is, the data such as the variety, quantity and destination of the fresh food, is extracted from the DB for analysis. For example, data is extracted from the DB depending on whether the fresh food is vegetable, whether it is fish, whether it is meat, order weight, distance to destination, and distance.

In the ninth step (S180), data on the delivered fresh food is extracted from the database, such as temperature, humidity, travel route, position of the container, and occurrence of abnormality.

For example, when the fresh food is transported, the inside temperature and the humidity of the packaging container (2) of the fresh food are ascertained, and the travel route is extracted as a highway, a national road, a city road, a coast road or a mountain road. And extracts data on whether the fresh food is loaded on the upper side of the container, middle side, lower side, inner side or outer side.

In addition, data on whether or not an abnormality has occurred in the fresh food transportation process is extracted, and in particular, data on the occurrence of an abnormality in the same kind, traveling route, temperature, and humidity are extracted.

In a tenth step (S190), the most suitable pattern is calculated at the time of fresh food transportation by combining the data with each other.

At this time, in the method of calculating an appropriate pattern, the condition data in the case where the delivery is completed stably is taken as a reference.

For example, in the case of transporting vegetables, the temperature and humidity are several degrees, and the reference data is used to calculate the position in the container and whether the delivery is completed stably when the traveling route is used. That is, when the vegetables are loaded on the upper side of the container at a temperature of 25 degrees and then delivered through the highway, the data of the case of being delivered in the freshest condition is calculated as reference data.

A condition in which an abnormality can occur by combining data in the case where abnormality occurs in the reference data with the reference data is excluded from the reference data.

For example, if the above-mentioned reference data was delivered through the expressway at a temperature of 25 ° C, but if the product was loaded on the lower side of the container, if the fresh food had an abnormality, So as not to be mounted on the lower side.

Accordingly, when fresh food of the same kind is transported, it is patterned so as to be loaded on the upper side or the middle of the container, and if the abnormality occurs when it is loaded in the middle of the container under the same conditions in the future, the intermediate load is deleted from the fresh food transportation pattern.

Also, by applying the discomfort items retrieved online on the fresh food transportation pattern, this inconvenience is applied in the reference data to improve.

In this way, the reference data is set in a primary way, the abnormal data is applied in a second order, and the third order is feedback of inconveniences to calculate the optimal fresh food transportation pattern.
