Description

TECHNICAL MANAGEMENT SYSTEM AND METHOD WHICH HAS A COMMODITY PAST RECORD GUARANTEE FUNCTION}

The present invention relates to an article management system having a product history guarantee function and a method thereof, and more particularly, to manage information on a production subject of a management subject (eg, articles, goods, agricultural and livestock products, livestock products, etc.) by actual coordinates. This provides a clear basis for the history of the country of origin and enables real-time monitoring of production, distribution, and sales of goods.

Barcodes are letters, numbers, and symbols that are easily read by a combination of thin bars (black bars) and spaces (white bars). This enables expression of information, collection and decryption of information. Barcodes are used for rapid and accurate processing of large amounts of data, such as hospitals, libraries, railways, passengers and cargo management, factory automation and office automation, as well as distribution operations such as sales and inventory management.

Radio identification (RFID) systems, on the other hand, incorporate the use of electromagnetic or electrostatic coupling within the radio frequency of the electromagnetic spectrum portion to identify certain objects in the field of distribution and logistics. This RFID system is a technology that can replace the barcode, which is less likely to be damaged than the barcode, and can read multiple tags at the same time at high speed. Even if an obstacle exists, it can be read, read and written, and reused. In addition, a low frequency RFID system (30KHz ~ 500KHz) is used in a short transmission area of about 1.8m or less, and a high frequency RFID system (850MHz ~ 950MHz and 2.4GHz ~ 2.5GHz) is used in a transmission area of a long distance of 27m or more. Inventory management, container / pallet / box management, automatic inspection, incoming / outgoing management, automatic sorting, rental goods management, counterfeit goods identification, anti-theft, cargo and goods tracking management. For example, an RFID system includes an RFID tag attached to a predetermined article and storing information on the article, an antenna for transmitting and receiving the RFID tag and predetermined data, and an RFID tag communicating with the RFID tag through the antenna. An RFID reader for controlling the operation of the tag, and a host computer for collecting and managing data of the RFID tag provided by the RFID reader.

In other words, the RFID system includes a chip on the product that contains information about the entire process of production, distribution, storage and consumption, or a reader to read the information and integrate it with the information system. It is used.

As described above, the construction of a system using bar codes and RFID has been progressed in various fields. For example, agricultural products such as rice go through the cultivation and production process consisting of selection, seeding, sowing, handing over, harvesting, and harvesting of rice (rice) performed in the producing farm, and finally through milling and processing. It is delivered to and consumed by the consumer. However, there is not only a reliable history system of the information on the cultivation and production process of the rice, but also a number of problems frequently occur at the producer and the road, the intermediate distribution process and the transition to the consumer. The same is true of vegetables and fruits as well as rice. Currently, the food labeling system and the labeling system of origin for agricultural products are implemented, but it is not easy to distinguish between exact varieties, so cheap imported products are sold as domestic products in the cultivation and production process, and there is a lot of confusion between food brands. Recently, consumer anxiety about agricultural products is being accelerated in connection with scientific problems such as genetic manipulation, but there is no way to track the cause and place of occurrence when such problems occur.

This problem is similarly occurred not only in agricultural products, but also in livestock products, aquatic products, and industrial products (articles). In particular, even if the country of origin is labeled as false, the authenticity of the consumer is difficult.

It is an object of the present invention to provide an article management system and method capable of presenting a clear basis for a history of origin and the like by managing information on a production subject of a managed subject by actual coordinates.

It is another object of the present invention to provide an article management system and method capable of real-time monitoring of production, distribution, sale, etc. of articles having a guaranteed history of origin.

According to one aspect of the present invention, an article management system and method having a history guarantee function capable of presenting a clear basis for a history of origin and the like is disclosed. According to the present invention, a device-specific reference coordinate is set for each radio ID (RFID) writer, and the maximum allowable distance from the reference coordinate is set. When the tag information is recorded, when the separation distance between the current coordinates of the RFID writer and the reference coordinate is within the maximum separation distance, the RFID router records the tag information in the RFID tag.

According to an embodiment of the present invention, the server registers the tag information read from the RFID tag through the RFID reader in the DB, collects the surrounding environment data of the managed object to which the RFID tag is attached or mounted, and integrates the tag information together with the tag information. Manage and monitor

According to the present invention, the information on the place of origin of the managed object is managed by actual coordinates to provide a clear basis for managing the history of origin, and the current state of the managed object is monitored in real time to increase the efficiency of management and Even at the time of shipment, by providing the current coordinates of the person in charge of shipping, there is an advantage that can improve the reliability of the shipment of goods. Through this series of processes, it is possible to efficiently manage a series of logistics systems from the production stage to the distribution and sales stages, thereby increasing work efficiency, reducing related costs, and increasing customer satisfaction.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, in the following description, when there is a risk of unnecessarily obscuring the gist of the present invention, a detailed description of well-known functions and configurations will be omitted.

The difference between RFID and barcode is as follows.

Barcodes can also be duplicated when copying industrial products. However, when RFID is applied, the information in the tag is encrypted and uses the proprietary system of the applying company, so the industrial product itself cannot be copied even though the RFID itself can be copied. In other words, products distributed by barcodes cannot be distinguished from cloned industrial products and barcodes, but industrial products embedded with RFID information are identified as duplicated industrial products if there is no reaction when scanning them with a recognition device, for example, an RFID reader. Even if another RFID tag is put in the product, the unique ID cannot be scanned because the unique system in the chip is encrypted. In addition, since the recognition device, for example, the scanning device, the RFID tag, and the communication protocol are 1: 1, the unique information cannot be read even if the unique system encryption on the chip memory is solved.

In bar code, it is difficult to manage individual parts because of the high labor cost and slow reading speed because the items must be identified 1: 1 when managing inventory and receipt. However, when the RFID tag is used, multiple readings of 1: N are possible, thereby facilitating inventory and receipt and departure management. In addition, in the case of using the RFID tag, it is possible to read from a long distance, it is possible to manage the history of the article by reading the article within a long distance, for example, 5m.

Since RFID can store a certain memory, it is possible to embed production information, distribution information, etc. of individual products, and when reading an RFID tag anytime and anywhere, the production information, distribution information, and sales information can be known. However, since the barcode represents only a simple serial number, other information cannot be displayed by itself, and no information can be viewed unless a database (DB) associated with the serial number is established.

Barcodes cannot be read when they are physically erased or modified, but RFID has a solid external shape, so there is no problem of erasing or deformation, and thermal, chemical and physical specifications can be presented through external environmental data.

If an external material or object is present between the barcode and the scanner, it is impossible to read. However, RFID has a penetrating power of radio waves, so it can be read through the external material or object. Therefore, in the case of industrial products it can be managed by embedding the RFID tag in the invisible inside of the article.

Thus, in the preferred embodiment of the present invention will be described taking the RFID as an example.

1 is a view schematically showing the configuration of an article management system according to the present invention.

The article management system performs an RF communication with the RFID tag 11 attached to the article 10 (e.g., agricultural products, industrial products, etc.) and the RFID tag 11, and particularly tags the article 10 at the production stage. Performs RF wireless communication and / or RS-232 wired communication with the RFID reader / writer 20 that records information (coordinate information, ID number, time information, etc.) and the RFID reader / writer 20. Control device 30 for processing and managing information about the article 10, and wireless communication (e.g., CDMA mobile communication, etc.) or wired communication (e.g., RS-232 wired communication, etc.) with the control device 30 And the main server 40 which comprehensively manages the information on the goods 10 for each client (to perform overall monitoring of the production, distribution, and sales of the goods), and the production of the goods 10 for each client. And a DB 50 for storing distribution and sales information.

Here, the RFID reader / writer 20 and the control device 30 are installed for each client, and can be configured in one piece or in a separate type. In addition, in the case of the detachable type, at least one or more RFID readers / writers 20 may be connected to one control device 30 (in this case, the RFID readers / writers 20 may be a secret house, a production / processing factory, a warehouse). Can be installed in each vehicle, vehicle, and place of sale]. In addition, the main server 40 is installed at a remote location, and comprehensively manages the article 10 for each client.

In particular, the tag information written to the RFID tag 11 in the production stage is based on the reference coordinates of the RFID reader / writer 20 according to the type of the article 10 (for example, agricultural products and industrial products). The distance (separation distance) of the current coordinates can be different or not recorded based on this. For example, agricultural products can record tag information even when the separation distance is 100 to 200 m, and the industrial product is the separation distance. The tag information can be restricted to record only when there is no. At this time, the reference coordinate is a device-specific latitude and longitude coordinate value stored in advance in the hardlock device by the responsible administrator, and the current coordinate is a latitude and longitude coordinate value measured in real time based on the GPS receiver 21. to be.

However, regardless of the separation distance according to the type of article 10, it should be noted that the RFID reader / writer 20 and the control device 30 can be fixed or detachable. Meanwhile, depending on the number of RFID readers / writers 20 and the recognition range of the RFID tags 10 of the RFID readers / writers 20, the RFID readers / writers 20 and the control device 30 may be integrated or separated. . However, in the case of the detachable configuration, the RFID reader / writer 20 is movable and the control device 30 is preferably fixed. In the case of the integrated configuration, the RFID reader / writer 20 and the control device 30 are Both mobile and stationary are possible. However, even when configured as a separate type, each of the RFID reader / writer 20 and the control device 30 can be configured as a fixed type.

Hereinafter, referring to FIG. 2, a separate configuration of the RFID reader / writer 20 and the control device 30 will be described as an example. In this case, the RFID reader / writer 20 may be configured to be mobile or fixed, and the control device 30 may be configured to be fixed.

The RFID reader / writer 20 performs RF wireless communication with the RFID tag 11 and transmits data to the control device 30 through wired or wireless communication (eg, RF wireless communication, RS-232 wired communication, etc.). The control device 30 allows data management.

The RFID reader / writer 20 is an apparatus for reading data from the RFID tag 11 and recording tag information (coordinate information, article identification number (ID), time information, etc.) on the RFID tag 11 by using wireless. An antenna 201, a reader 202, a recording unit 203, a control unit 204, a GPS receiver 21, a storage unit 205, and the like are provided.

The antenna 201 wirelessly transmits and receives data with the RFID tag 11 based on a data read request from the reader 202 and a data write request from the recorder 203.

The reading unit 202 is a processing unit which transmits a data reading request to the RFID tag 11 and receives data requested from the RFID tag 11. Specifically, the reading unit 202 is provided with tag information (coordinate information, article unique number (ID), Time information, etc.), a storage address of the data, and a data length are designated to request reading of the data. The process of the RFID reader / writer 20 reading RFID data from the RFID tag 11 follows a known technique.

The recording unit 203 is a processing unit which transmits a data recording request together with the data recorded on the RFID tag 11, specifically, tag information (coordinate information, article identification number (ID), time information, etc.), storage address of data. And specifying data to request recording of the data. The process of the RFID reader / writer 20 writing RFID data to the RFID tag 11 follows a known technique. However, in the present invention, the recording unit 203 may or may not record the tag information in the RFID tag 11 according to the distance (separation distance) of the reference coordinate and the current coordinate of the RFID reader / writer 20 in the production stage. In this way, the data recorded in the RFID tag 11 by the recording unit 203 is read out later by the reading unit 202.

In particular, the control unit 204 receives the reference coordinates (latitude and longitude values) stored inside the hardlock device (which becomes the storage unit 205) and the GPS receiver 21 in advance by the responsible manager in the production stage. The distance (separation distance) of the present current coordinates (latitude and longitude values), and the RFID tag of the article 10 only if the separation distance is less than the maximum separation distance (for example, 200 m for agricultural products, 30 cm for industrial products, etc.). 11), the recording unit 203 is controlled to record tag information (coordinate information, article unique number (ID), time information, and the like). However, when the separation distance exceeds the maximum separation distance, the tag information is controlled not to be recorded in the RFID tag 11 of the article 10. This is to increase the reliability of the article 10 by clarifying the origin of the article 10 in the production stage.

The RFID tag 11 is a wireless IC tag that stores information about the article 10 for each article. The RFID tag 11 includes an antenna 114, a transmitter 112, a receiver 113, a storage 111, and the like. The RFID tag 11 follows a known technique. However, in the present invention, the RFID tag 11 records the tag information only within the maximum separation distance (threshold) according to the distance (separation distance) between the reference coordinate and the current coordinate of the RFID reader / writer 20 in the production stage.

The antenna 114 is a processor that wirelessly transmits and receives data with the RFID reader / writer 20, and transmits data from the transmitter 112 and transmits the received data to the receiver 113.

The transmitter 112 transmits data recorded in the storage 111 to the RFID reader / writer 20 through the antenna 114 in response to a data read request from the RFID reader / writer 20.

In particular, the receiving unit 113 stores data received from the RFID reader / writer 20 via the antenna 114 (in particular, tag information at the production stage) in response to a data recording request from the RFID reader / writer 20. Stored in the unit 111.

In addition to the tag information (coordinate information, ID number, time information, etc.) recorded at the production stage, the storage unit 111 stores time information stored in the ordinary RFID tag 11 (eg, manufacturing of fish food). Time information), place information (e.g., manufacturing place information of fish food), storage place information (e.g., wearing information indicating the time of receipt into a frozen warehouse), and the like. The coordinate information among the tag information is the current coordinate (latitude and longitude value) received through the GPS receiver 21 of the RFID reader / writer 20 at first, and then the position of the article 10 is changed (for example, In this case, the current coordinate is updated with the latest value (in this case, the history of the coordinate information remains). When the tag information is recorded in the RFID tag 11, it is stored and managed for each client in the DB 50 of the main server 40, and the temperature / humidity data around the article 10 and the current coordinates (updated current coordinates). And integrated management).

In the present invention, the RFID tag 11 and the RFID reader / writer 20 for wireless identification thereof are based on a known technique. In particular, in the production stage, the distance (separation distance) between the reference coordinate and the current coordinate is a threshold value (maximum separation distance). The tag information (coordinate information, ID number, time information, etc.) is recorded in the article 10 only when it is less than one, so that the origin of the article 10 to be managed is made clear. It can increase the reliability.

The control device 30 performs RF wireless communication or / and RS-232 wired communication with the RFID reader / writer 20, processes and manages the information on the article 10, and transmits and receives the wired / wireless communication to the main server 40. For example, the data is transmitted through CDMA mobile communication, RS-232 wired communication, etc., so that the main server 40 can collectively manage data for the article 10 for each client. In addition, the control device 30 measures and measures the temperature and humidity (eg, temperature and humidity of a secret house, a freezer, etc.) at a predetermined time interval using the temperature sensor 302 and the humidity sensor 303 ( For example, temperature and humidity data) is transmitted to the main server 40 so that the main server 40 can be integrated and managed together with the RFID information (including tag information) of the article 10. In addition, the control device 30 includes a GPS receiver 309 for tracking and managing the position of the article 10, and when the position of the registered article 10 is changed (e.g., made in a factory and stored in a warehouse). Etc.), the current coordinates received through the GPS receiver 309 are transmitted to the main server 40, and the main server 40 is integrated with the tag information and the temperature / humidity data around the article 10. To manage it. In addition, when the shipment request of the article 10, the control device 30 transmits the position coordinates received through the GPS receiver 309 to the main server 40, the main server 40 based on this article 10 To control the shipment.

As shown in the figure, the control device 30 is a transceiver (e.g., an antenna, a CDMA wireless communication module, an RS-232 wired communication module, etc.) 301 and 307 corresponding to a general PC, PDA, mobile communication terminal, etc. 304, a user input unit 305, a display unit 306, a storage unit 308, and the like.

In the above, the case in which the control device 30 includes temperature and humidity sensors 302 and 303 to record and manage temperature and humidity data together with RFID information (tag information, etc.) of the article 10 is described. The RFID reader / writer 20, which can be attached to a storage warehouse, a freezer, a transport vehicle, or the like, has an independent temperature and humidity sensor or works in conjunction with a separate temperature and humidity sensor provided near the article 10, thereby providing an RFID reader. Measure the temperature and humidity data directly from the / writer 20 and transmits it to the main server 40 through the control device 30, integrated with the tag information of the article 10 in the main server 40 management Make it possible. In addition, the RFID reader / writer 20 transmits the current coordinates to the main server 40 when the location of the registered article 10 is changed (for example, when it is made in a factory and stored in a warehouse). In the main server 40, the tag information and the temperature / humidity data around the article 10 may be integrated and managed.

The control device 30 can inquire information of the relevant agricultural products, industrial products, etc. from the production stage (including RFID production, management, shipping) to the distribution and sales stages, and users can control the control device 30 or other Through wired or wireless connection to the main server 40 via a communication device (mobile communication terminal, PDA, PC, laptop, etc.), the information about the own item 10 registered in the DB 50 can be inquired. have.

Thus, the control unit 304 of the control device 30, the sensor data input and output communication port, GPS data input port, CDMA communication port, Zigbee communication port, RS-232 communication port, button input and display as shown in FIG. An output port and the like.

The main server 40 may monitor the number of tag information recorded in the RFID tag 11 in the production stage and inform the manager of this. For example, if the manager knows that there are 10 items 10 produced in one day, and 11 pieces of malicious tag information are added, 11, the main server 40 receives the total daily output ( 11) to the manager (notification via e-mail, SMS, MMS, etc.), and upon confirmation of the manager (in this case, the manager will not accept the confirmation of the total output per day). again be informed to the administrator, the administrator can be prevented from cheating by ever final confirmation (e.g., employee misconduct, etc.) [RFID production. In addition, the main server 40 stores and manages the current coordinates of the article 10, so that if the article 10 is out of a certain range (for example, outside the factory, outside the farmland, etc.), the main server 40 can notify the manager and take action. [Management] . In addition, the main server 40 stores and manages temperature and humidity data, so if an item affected by temperature and humidity, such as a vegetable, is out of a predetermined temperature and humidity, the administrator can notify the administrator and take action. [Management] . In addition, the main server 40 tracks and manages the location of the requestor when the shipment of the article 10 is requested. Thus, the current coordinates (coordinate information recorded as tag information) and the position coordinates of the article 10 may be controlled by the control device. 30) location information obtained by the GPS receiver 309 in] matches or controls ever shipped to the article 10 only when present within the predetermined range [shipment. In this case, the main server 40 may compare the last year's shipments with the current year's shipments and inform the manager of statistics and analysis information (increase or decrease the shipments since the shipments are xx). In addition, the main server 40 collectively manages and monitors not only the production stage (RFID production, management, shipment) of the article 10 but also the distribution and sales stage.

Here, the process from RFID production, management, and shipping is the 'production stage', which will be described below. The distribution and sales steps after the production step follow known techniques.

Hereinafter, the overall process of the article management method will be described with reference to FIG. 4 and the detailed process will be described with reference to FIGS. 5 to 8.

First, a target (RFID tag) existing in a predetermined range is selected from the reference coordinates set in the RFID reader / writer 20 and the necessary information (tag information) is recorded (RFID initialization process) (401). That is, the tag information is recorded or not recorded in the RFID tag 11 according to the distance (separation distance) of the reference coordinate and the current coordinate of the RFID reader / writer 20 in the production stage. For example, a distance between a reference coordinate (latitude and longitude value) stored inside a hardlock device (which becomes the storage unit 205) and a current coordinate (latitude and longitude value) received through the GPS receiver 21. When the separation distance is less than the maximum separation distance (for example, 200m agricultural products, 30cm industrial products, etc.), the tag information (coordinate information, article identification number) on the RFID tag 11 of the article 10 , Time information, etc.), and when the separation distance exceeds the maximum separation distance, tag information is not recorded on the RFID tag 11 of the article 10.

When the RFID initialization is completed, the information of the management object (article) is read by the RFID reader / writer 20, sent to the remote main server 40 through the control device 30, and registered as a new management object ( 402).

With respect to all registered management objects (articles), after obtaining RFID information (tag information, etc.) from the RFID reader / writer 20 (403), various sensors in the RFID reader / writer 20 or the control device 30 are obtained. (E.g., temperature / humidity sensor, etc.) and data (e.g., temperature and humidity data, current location coordinates, etc.) acquired through the GPS receivers 21 and 309 are transmitted to the remote main server 40 together with the item unique number (ID). (403, 404).

The main server 40 then updates and integrates the information of the article 10 with the latest information (406). That is, temperature / humidity data and current coordinates of the surroundings of the article 10 are mapped to the tag information of the management object (article) registered for each client and managed together. In addition, the main server 40 compares and analyzes RFID information (tag information, temperature / humidity data, etc.) of the DB 50 and performs real-time monitoring (407) to influence temperature and humidity, such as vegetables, for example. If a situation in which the received article 10 deviates from a predetermined temperature and humidity occurs, the manager is notified in advance so that precautions can be taken. As another example, when requesting the shipment of the goods (the location information of the shipment requester is transmitted together), the location of the shipment requester is tracked and managed so that the current coordinates (coordinate information recorded (or updated) as the tag information) and the location of the goods 10 are tracked. By controlling the shipment of the article 10 only when the coordinates (location information obtained through the GPS receiver 309 in the control device 30 at the time of shipment request) are within a predetermined range or the predetermined range, To block the shipment of goods at any place. Here, the position information (position coordinates) of the shipment requester is a latitude and longitude value measured by a GPS receiver mounted on the terminal requested by the shipment requester. In this case, the control device 30 is assumed, but may be other terminals. Care must be taken.

In addition, the main server 40 performs overall management not only in the production stage but also in the distribution and sales stage.

Referring to FIG. 5, the RFID initialization process 401 will be described in detail.

The RFID tag 11 is a tag attached to an actual management object (article), and stores necessary information therein (coordinate information of the article, product identification number (ID), visual information, etc.), and an RFID reader / writer ( RFID information is read and transmitted to the control device 30 via wireless communication. In this case, reference coordinates are set in advance in the RFID reader / writer 20 for initializing the RFID tag 11 (501), and a maximum separation distance at which the article 10 can be registered from the reference coordinates is set (502). In this case, the separation distance is a distance value between the current coordinate received through the GPS receiver 21 and the preset reference coordinate, and the maximum separation distance is a tag information recording threshold (that is, a threshold that permits / disallows recording of tag information).

Thereafter, the current coordinates are acquired through the GPS receiver 21 (503), and the tag information is RFID tag according to the distance (separation distance) between the current coordinates received through the GPS receiver 21 and a preset reference coordinate (504). (11) or do not record (506). For example, a distance between a reference coordinate (latitude and longitude value) stored inside a hardlock device (which becomes the storage unit 205) and a current coordinate (latitude and longitude value) received through the GPS receiver 21. Is less than the maximum separation distance (for example, 200m for agricultural products, 30cm for industrial products, etc.), the tag information (coordinate information, ID number, time information, etc.) is applied to the RFID tag 11 of the article 10. If the separation distance exceeds the maximum separation distance, the tag information is not recorded in the RFID tag 11 of the article 10.

This process is performed for the purpose of clarifying the origin of the article 10 to be managed, so as to improve the reliability when the subject (article) is commercialized. At this time, the setting of the reference coordinate is stored in the hardlock device mounted in the RFID reader / writer 20 in advance by the responsible administrator, thereby preventing arbitrary recording by the actual operator. In addition, the coordinate information (basic coordinates) of the management object (article) input through the above process is the current coordinate acquired from the GPS receiver 21 mounted on the RFID reader / writer 20 when the management object has mobility. It is used as data to calculate the separation distance from the first registered position by the relative distance calculation from [update of the current coordinate]. In the case of a managed object that is out of a certain range by such a function, it is determined whether a problem occurs through analysis of the cause, etc., and the administrator is always informed of the managed object that is finally identified as having a problem by providing an optimal management state. You can create a working environment to maintain.

Referring to FIG. 6, a process 402 of registering the information of the management object (article) of which RFID initialization is completed to the DB 50 of the main server 40 of the remote location will be described in detail.

When the RFID initialization is completed, the information of the management object (article) is read by the RFID reader / writer 20 (601) and then transmitted to the control device 30 via RF wireless communication (602), which is again remote The main server 40 is transmitted via CDMA wireless communication (or RS-232 wired communication) (603).

The main server 40 checks the integrity of the data (604) and registers as a new management object (605). In other words, tag information (coordinate information, article unique number (ID), time information, etc.) of the management object (article) is stored and managed in the DB 50 of the main server 40.

As such, after receiving the information (tag information) read through the RFID reader / writer 20 from the RFID tag 11 attached to the management object, it is registered in the DB 50 managed by the main server 40 of the remote place. do. Through this process, a newly registered management object is integrated in the DB 50 and monitored in real time when there are previously registered management objects of the same client.

Referring to FIG. 7, the main server 40 updates, integrates and manages the information of the article 10 with the latest information to compare, analyze and monitor RFID information (tag information, temperature / humidity data, etc.) in real time. The process (404 ~ 407) will be described in detail.

The manager sets conditions for the external environment (eg, temperature, humidity, moving range, etc.) of the management object (article) (701).

The RFID tag 11 attached to the control device 30 and the management object continues to exchange information by wireless communication through the RFID reader / writer 20. In this process, the information (tag information) in the RFID tag 11 and the GPS receiver 309 embedded in the control device 30 (or the GPS receiver 21 embedded in the RFID reader / writer 20) are acquired. The information (temperature and humidity data) acquired through the data (current position as GPS data) and various sensors (temperature sensor, humidity sensor, etc.) are integrated with each other and processed and processed into more useful information (702,703).

At this time, during the communication process between the RFID tag 11 and the control device 30, the management object that is out of a given condition is detected. For example, if an object affected by temperature and humidity, such as a vegetable, is selected as a management object, if a situation outside of a given condition (predetermined temperature and humidity) 701 occurs (704), the manager is notified and the cause analysis is performed. And to prepare to prepare a follow-up countermeasure (705). Particularly, in the present invention, when the RFID information (for example, coordinate information) attached to the registered management object is changed (702), it is classified as a special management object and notified to the main server 40 (707), It is possible to thoroughly filter out damage and intentional information change of the RFID tag (11).

The main server 40 updates and integrates the information of the article 10 with the latest information (708). In other words, the temperature / humidity data and the current coordinates around the article 10 are mapped to the tag information of the management object (article) registered for each client and managed together. [In this case, the coordinate information is updated from the initial registration. Manages the entire history up to the process]. The RFID information (tag information, temperature / humidity data, etc.) of the DB 50 is compared and analyzed and real-time monitoring is performed (709). In particular, we conduct ongoing location tracking and monitoring for special management targets, and report this situation to managers on an ongoing basis.

The shipment request control process 408 of the management object (article) will be described in detail with reference to FIG. 8.

The management object (article) registered in the DB 50 is managed in real time. If a managed item is to be shipped, the current requester's current location is provided to the main server 40 (801,802).

The main server 40 records the position coordinates acquired through the GPS receiver built in the requesting device of the shipment requester (eg, the control device 30) and the current coordinates (tag information) of the article 10 ( (Or updated) coordinate information], and compares (803) the approved article 10 to be shipped only when it is matched or within a predetermined range (804). This is to block the request for the shipment of goods at any place by any worker.
