Description

Fresh product distribution system and method through IOT based and big data algorithm analysis

The present invention relates to a fresh goods distribution system and method, and more particularly to a technology that can clearly grasp the current state of the fresh goods by monitoring the various environmental conditions such as the temperature when shipping fresh goods.

In general, the food distribution process consists of a process in which a producer produces a food, and then a consumer purchases the necessary food after being distributed through a distributor.

In this food distribution process, the food to be distributed must be delivered freshly and stably. In the case of processed and natural foods, the goods ordered by the consumer are returned to be disposed of in an order quantity of about 15% to 25%. In addition, the total cost of domestic and exports is wasted in the country as a whole. (Korea Consumer Resources: 2 trillion 200 billion annual savings when saving 5% of processed food waste)

In addition, since the freshness of the food ordered by consumers is not maintained, disputes between "producers, distributors, and consumers" have not ceased, and fresh foods considering social waste and national food economy security due to environmental pollution of food waste disposal. The distribution management system needs to be improved.

Since the food distribution process goes through several stages, the distribution time is long, and in this process, the food may be deteriorated due to factors such as temperature. Therefore, techniques have been attempted to distribute food in a fresh state.

These techniques are being tried in various forms, an example of which is given in patent application 10-2013-54125 (name: individual cargo monitoring method inside the container).

This prior art can be provided with tag information for individual cargo loaded using a relay mounted on the container, and the management device can track the security and location of the individual cargo loaded into the container until the container reaches its destination. Can manage At this time, the information reported in the container is a unique address, temperature, humidity and the like.

However, the prior art is a method of transmitting a corresponding information by mounting a wireless tag such as a temperature sensor and a wireless sensor tag on the container, such a sensor is mounted on the container to transmit the temperature information about the entire space inside the container As a technology, it is difficult to grasp individual temperature information for each cargo loaded in a container.

In particular, each cargo loaded in the container is a variety of foods, industrial products, and various kinds, and even in foods, fish, vegetables, fruits, etc., each species is different in temperature requirements for freshness.

Therefore, when sensing and transmitting the temperature information of the entire interior of the container as in the prior art, it is possible to monitor the internal temperature of the entire container, but it is difficult to grasp the temperature for each cargo, the food deteriorated after transportation If there is a problem, there is a problem in determining responsibility.

In other words, if the temperature inside the container is about 20 degrees, which is suitable for fruits, etc., but this temperature may not be suitable for fish, the carrier insists that it is not responsible for maintaining the temperature of 20 degrees. Can be held accountable.

In addition, in order to solve such a problem, when the temperature sensor and the wireless tag are integrally mounted on the packaging case of each cargo, it is difficult to recover the sensor and the tag.

In other words, the recovery is difficult because the temperature sensor and the tag is placed in the interior of the packaging container. Once placed inside, the shipper may open the packaging container arbitrarily before the consumer opens the packaging container and recovers the sensor and the tag. Because it is difficult.

This is because most of them are delivered to the guard room or storage box when they are absent, and the shipper cannot arbitrarily damage the packing container.

As such, since packaging containers of cargo are difficult to recover after transportation, the sensors and tags mounted on the packaging containers are often discarded as they are. In this case, logistics costs increase due to the manufacturing cost of the sensors and tags. .

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

Therefore, the present invention has been proposed to solve the above problems, an object of the present invention is to improve the temperature sensor and the tag in a separate type by placing the temperature sensor on the inside of the packaging container and the tag on the outside, the delivery person is a consumer When delivering the goods to the cargo to recover only the tag on the outside and the inner temperature sensor to provide a technology that can reduce the logistics cost by increasing the recovery rate of the tag.

In addition, by developing and applying big data algorithm analysis technique to consumer's complaints, the technology to prevent waste of national budget by reducing national food safety cost due to food waste of producer / distributor (shipper). To provide.

In addition, when transporting the packaging container, it is to provide a technology that can prevent the deformation of the packaging container having a flexibility, such as crushed by the external force when combining the detachable sensor and the wireless sensor tag.

The present invention relates to a system and method for transporting a product in a fresh state by grasping the temperature and humidity of the product in real time. The target product includes not only food but also cosmetics, vaccines, refrigerated meat and dairy products requiring temperature control. It demonstrates with the following food.

1 to 5, the fresh goods distribution system proposed by the present invention measures the internal temperature of the food packaging container 2 loaded in the container of the vehicle 1, and outputs a measured value sensor (3); A detachable sensor 3 is detachably coupled to the wireless sensor tag 7 in which measurement data input from the detachable sensor 3 is stored and output; A reader 8 for reading information of the wireless sensor tag 7 and outputting a result; A communication unit 10 for reading the information of the wireless sensor tag 7 and transmitting it through a network; And a management host 6 which receives the information transmitted from the communication unit 10 and grasps the current state of the fresh goods in real time.

In the 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, the inside temperature of the container in which the fresh food is packaged can be measured.

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

The plurality of pins 12 may be arranged in various ways according to a standard, for example, using protocols such as RS422, RS485, LAN, LIN, CAN, LVDS, and the like. RX) may be arranged in two pins or the like. At this time, by assigning one of the plurality of pins 12 to transmit an 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 appreciated 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 may obtain temperature data by transmitting and receiving a signal with the temperature sensor 9 through the plurality of pins 12.

The humidity sensor includes a method of using a change in electrical resistance or capacitance caused by moisture absorption into porous ceramics or a polymer membrane, a method of using a change in resonant frequency of the vibrator due to a change in weight of an absorbing material installed in the vibrator, and the like. . Such a humidity sensor may also be disposed inside the packaging container 2 to measure humidity.

The humidity sensor may be installed integrally with the temperature sensor 9 or may be separately installed. Alternatively, 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 includes 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. The wireless sensor tag 7 is divided into a place and a purpose used for each frequency band.

For example, the UHF method uses frequencies of 433, 9100 MHz, and 2.45 GHz microwave bands, and a data transmission / reception distance between the reader and the RFID tag is within a range of 5 m to 10 m. 430 MHz is primarily used for active tags, and 910 MHz is used for passive tags.

In addition, the HF method uses a frequency of 13.56Mhz band, and the data transmission / reception distance between the reader and the RFID tag is within a range of 1 cm to 3 cm. This HF method is mainly used for transportation and credit cards for security and safety reasons.

Dual tag type (Dual Tag) is a method of applying the UHF tag and the tag of the HF method at the same time. That is, as described above, the UHF method and the HF method have differences in use and performance. Thus, the two types of tags 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.

LF uses a frequency of 123 kHz.

In addition, the port 13 has a plurality of pin grooves 14 formed therein, and a plurality of pins 12 protruding from the terminal 11 are coupled to the pin grooves 14 so that data can be transmitted and received from a temperature and humidity sensor. have.

At this time, the port 13 can be arranged in various ways according to the standard as in the case of the terminal 11, for example, using a protocol such as RS422, RS485, LAN, LIN, CAN, LVDS, It may be arranged as a transmit (TX) 2-pin groove, a receive (RX) 2-pin groove.

At this time, by assigning one pin groove of the plurality of pin grooves 14 to transmit the On (On) signal when the terminal 11 of the temperature sensor 9 is coupled to the packaging container at the start of delivery in the management host (6) It can be appreciated that the temperature sensor 9 and the wireless sensor tag 7 are combined with each other in 2).

The analog block (A) is a voltage multiplier for generating a driving power of the wireless sensor tag (7) by a radio frequency signal applied from an antenna, a voltage limiter for limiting the magnitude of the voltage and outputting it to the click generation unit, and digital A modulator for modulating the response signal applied from the block and transmitting the modulated signal to the antenna, and a demodulator for detecting an operation command signal among frequency signals 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, interprets the signal, generates control signals, and processes signals, and outputs a response signal to the analog block. In addition, addresses (Address), input and output of temperature and humidity data, and control signals are output 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. The memory 19 may be a memory 19 of various methods, for example, a USER memory in which user data is stored, a TID memory in which manufacturing information of a tag is stored, an EPC memory in which information of a tag is stored, It consists of a reserved memory where passwords are stored.

On the other hand, the detachable sensor 3 and the wireless sensor tag (7) is attached to a packaging container used in the field of transportation, such as courier, such a packaging container is also a rigid container, but also made of paper material flexible packaging have.

In the case of a flexible packaging container, when the detachable sensor 3 is coupled to the wireless sensor tag 7, the packaging container may be deformed by an external force.

Therefore, it is important to quickly couple the detachable sensor 3 to the wireless sensor tag 7 with little force, as shown in FIG. 5.

That is, the first magnetic M1 is mounted on the tip of the plurality of pins 12 protruding from the terminal 11 of the detachable sensor 3, and the pin magnetic portion 14 of the corresponding wireless sensor tag 7 is mounted inside the pin groove 14. Mount the second magnetic (M2).

Therefore, when the plurality of pins 12 are inserted into the inlet of the pin groove 14, the pin 12 is quickly pressed by a small force inside the pin groove 14 by the magnetic force of the first and second magnetic (M1, M2). Can be combined.

Of course, the magnetic may be mounted on both the front end of the pin 12 or the inside of the pin groove 14, it may be mounted only on one side.

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

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

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

The reader 8 has a conventional structure, that is, the input unit 23, the processor core and the processor (Process Core; 27), the memory 29, the output unit 25, the system bus (System Bus), data It is composed of a printer (Printer) 31 and the like to output to the paper, by applying various frequency bands to read the data stored in the wireless sensor tag (7).

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

On the other hand, the distribution center (T) can deliver the food, the gate (G) is disposed at the entrance and exit of the distribution center (T) detects the entry and exit of the vehicle for food transport (1).

Such a gate (G) is installed in a dock, such as a distribution center (T), and there are 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.

Accordingly, when the fresh commodity transport vehicle 1 enters the gate G, the check reader of the gate G recognizes the vehicle 1. In this case, the recognized information includes the type of the vehicle 1, the date and time of entry and exit of the vehicle, and the like.

The inputted 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 has arrived or departed from the distribution center T. FIG.

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

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

This management host 6 preferably comprises a database, a web server, an APP host, and a local computer.

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

The web server is a server providing a web page (HTML file), and a web server program capable of providing a web page is installed. Therefore, users such as the producers P who are connected to the management host 6 can easily check the necessary information through the homepage.

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

Therefore, the manager can access the management host 6 via a local computer, and can proceed with processes such as history management, system management, and data transmission and reception of the temperature or humidity of the fresh food.

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

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

Therefore, the temperature or humidity information of the fresh food transmitted by the reader 8 and the communication unit 10 of the fresh food conveying vehicle 1 may be shared by the management host 6 and the user through a network.

In other words, the fresh food distributor through the management host (6) in real time to determine the current location of the fresh food transport vehicle (1), the departure and arrival of the distribution center (T), the temperature or humidity of each fresh food loaded in the container, etc. You can figure it out.

In addition, the management host 6 may transmit and receive temperature or humidity information to a portable terminal such as a smartphone through an access point (AP).

In addition, individual users can also access the management host 6 via a personal computer. Therefore, the current location, temperature, humidity information of the fresh food ordered can be confirmed in real time through the homepage.

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

As shown, the distribution management method of the fresh goods proposed by the present invention, the first step (S100) for attaching the detachable sensor (3) to the wireless sensor tag (7) mounted on the food container; A second step S110 of transmitting an on-signal to the management host when the terminal of the detachable sensor 3 is coupled to the port of the wireless sensor tag 7; A third step (S120) of the detachable sensor 3 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 transmitting the measured data from the wireless sensor tag 7 to the reader 8; The reader 8 includes a fifth step S140 of transmitting data to the management host 6 through the communication unit 10; A sixth step S150 of presenting temperature data of the product to the consumer C; And a seventh step S160 of calculating the appropriate temperature for each product by analyzing the measured temperature data by an analysis algorithm of big data.

In the distribution management method of the fresh food, in the first step (S100), the detachable sensor 3 and the wireless sensor tag 7 are mounted in a container in which the fresh food is packaged. That is, the terminal 11 mounted at one end of the temperature sensor 9 is coupled 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.

In this case, 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.

In the second step S110, a plurality of pins 12 protruding from the terminal 11 of the detachable sensor 3 may be coupled to the plurality of pin grooves 14 formed in the port 13 of the wireless sensor tag 7. At this time, the signal is transmitted to the management host 6 by the combination of the pin 12 and the pin groove 14 set to transmit the 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, the temperature and humidity data can be recognized. Manage.

In a third step S120, the temperature data transmitted from the temperature sensor 9 is stored in the memory 19 of the wireless sensor tag 7. In this case, various types of information are stored in the memory 19, for example, a variety of information such as the type of fresh goods, the order date, the orderer, the date of shipment, the place where the fresh goods are produced, the proper temperature, the internal temperature of the packaging container 2, and the like. Can be stored.

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

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

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

That is, the fresh food transport 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 analyzes the received temperature, humidity, and current location data through a big data analysis algorithm, so that the temperature or humidity history of the fresh food can be grasped in real time.

The analyzed data is then sent to the reader 8 so that the fresh food transporter can present this data to the consumer C.

In the sixth step (S150), by delivering the fresh food to the consumer (C) and presenting data, such as temperature for the fresh food, it can be proved that the fresh food has been transported in an appropriate state.

At this time, the transporter may show the corresponding data on the screen of the reader 8 or output it through a printer to show it in the form of a paper.

Consumers (C) can verify these data to confirm that the fresh food has been shipped under appropriate temperature and humidity conditions.

Of course, the consumer C may check the current state of the fresh product being delivered by accessing the home page 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 big data to calculate an appropriate temperature for each fresh food, and the feedback is communicated through the Internet to feed back the inconvenience. By solving this problem, the distribution system can be improved.

In more detail, the analysis process may include an eighth step S170 of extracting data such as temperature and humidity obtained each time the fresh goods are transported; A ninth step (S180) of extracting data on the actual state of the delivered fresh goods; And a tenth step (S190) of combining the data extracted in the eighth step (S170) and the ninth step (S180) and calculating the most suitable transportation pattern for each fresh product by searching for and extracting an online message.

In the eighth step (S170), the data input when the consumer C orders the fresh food, that is, the data such as the variety, quantity, shipping address, etc. of the fresh food is extracted from the DB for analysis. For example, data is extracted from a DB depending on whether fresh food is vegetables, fish, meat, order weight, and whether the destination is remote or near.

In the ninth step (S180), data is extracted from the DB on the temperature, humidity, driving route, the location loaded in the container, and whether or not an abnormality has occurred for the fresh food delivered.

For example, when the fresh food is transported, what is the internal temperature and humidity of the packaging 2 of the fresh food, the driving route is extracted whether the highway, national road, city driving, coastal road, mountain road. And it extracts data on whether the fresh food is loaded on the upper side, the middle side, the lower side, and the inner side or the outer side of the container.

In addition, it extracts data on whether or not an abnormality occurred in the fresh food transportation process, in particular, extracts the data on the case of the same varieties, driving route, temperature, humidity.

In the tenth step (S190) by combining the above data to calculate the most suitable pattern for fresh food transportation.

At this time, in the method of calculating a suitable pattern, it is based on the condition data when the delivery is completed stably first.

For example, in the case of transporting vegetables, the temperature and humidity are degrees, and the position loaded in the container, and in what driving route, are calculated based on the standard data. That is, when the vegetables are loaded on the upper side of the container at 25 degrees and then delivered through the highway, the data when the vegetables are delivered in the freshest state is calculated as reference data.

The condition that abnormality can occur by combining the data in the case of abnormality in delivery to the reference data is excluded from the reference data.

For example, if the vegetable, which is the reference data, was delivered through a highway at 25 ° C, but there was an abnormality in the fresh food when loaded below the container, the same varieties as the fresh food were calculated when the fresh food pattern was calculated. Calculate not to load underneath.

Therefore, when transporting fresh foods of the same varieties patterned to be loaded on the upper or middle of the container, if the load later occurs in the middle of the container under the same conditions, if the abnormality occurs in the fresh food transport pattern is deleted.

Then, by applying the inconveniences retrieved online to the fresh food transport pattern, the inconveniences are applied to the reference data to improve them.

In this way, the reference data is first set, the second data is applied sequentially, and then sequentially removed, and the third is a method of calculating an optimal fresh food transportation pattern by feeding back the inconvenience.

The present invention can be used in the field of distribution of goods as a technology that can clearly monitor the current status of fresh goods by monitoring the real-time environmental conditions, such as the temperature when transporting fresh goods by mounting the temperature sensor in a separate type in the packaging container It is a skill.
