Description

The present invention provides a field server group arranged for collecting production history information such as environment, growth, preservation state, processing, etc. and identification / specific information of agricultural products at each point where agricultural products are produced, processed, moved, and stored. The present invention relates to an agricultural product tracking system that collects information and tracks agricultural products from the production site of agricultural products to the end user and verifies and confirms the identity of agricultural products produced at the point.

In the conventional individual authentication technology, an identifier such as an RF-ID is assigned to a target article or person, and the identity is authenticated by combining it with a method such as encryption. There was a problem that it would not work if replaced. Biometrics authentication methods that use fingerprints for identification are less likely to be modified, but are vulnerable if modifications are made to devices that read fingerprints,
In addition, there is a possibility of being misrepresented by artificially creating a simulated object having the same pattern as a fingerprint.

  The conventional traceability system is a system that realizes retrospective possibility to quickly investigate the cause of occurrence when there is any defect in products such as agricultural products and foods (hereinafter referred to as “product”). When producers, distributors or retailers skillfully tried to misrepresent the quality of the product or replaced only the contents of the packaging, it was difficult to see it. In order to ensure that the product delivered to the consumer has the quality and production history as indicated on the quality label, the user should keep an eye on for a moment from the start of the production process to the consumer. However, it was difficult to achieve this.

  In addition, when the contents are replaced with a skillfully made fake, it is difficult to accurately determine the content by image recognition technology such as pattern matching. If you are going to do it, you need to see and appraise with the eyes of an expert like a jewel. However, it was virtually impossible for experts to appraise large quantities and inexpensive products such as agricultural products.

  In order to provide consumers with a sense of security by indicating that the pesticide-free vegetables were truly pesticide-free cultivation or that the cultivated agricultural products were produced in the field of the farm, the farm should always be kept in weather and environmental conditions. Need to monitor the information and show it to consumers without wrapping up the information. In addition, knowing that such monitoring is being done allows the consumer to trust the producer. Such an outdoor monitoring system is composed of a large number of measuring devices and communication devices, and it is difficult to install them outdoors and in the distribution process in terms of weather resistance and cost, and such a complicated system is actually used. It was difficult to operate.

  The field server is a device provided with a plurality of environmental measurement sensors and communication means such as a wireless LAN, and can acquire environmental information at the production site in real time. However, the conventional field server has not provided a means for acquiring information about agricultural products and tracking the movement from the production site to the end user.

  Further, after the agricultural products are produced and harvested in the above-mentioned field, it is necessary to prevent impersonation such as replacement in the movement / conveyance route. A system capable of dealing with such problems has not been considered. In addition, devices equipped with various types of monitoring used in conventional farms and communication networks for such information have not been considered for dealing with the following problems.

Measurements related to weather, organisms, agricultural products, and foods require measurements related to crops, sensors such as soil moisture, plant moisture, and leaf wetness. In addition, regarding weather and environment, temperature, humidity, wind speed / wind direction meter, solar radiation sensor, etc. are also required.
Furthermore, many kinds of measuring devices such as a camera, a communication device, and a GPS for obtaining an image in real time are required as an on-site monitoring system. Conventionally, in order to obtain on-site information, such devices are individually installed.

In the conventional method, in order to install such an apparatus, a large apparatus and a large area for installing the apparatus are required, and the number of man-hours for installation becomes enormous. The field server has a major feature in that it reduces the manufacturing cost and installation cost by combining such things into one module, but it also has a significant cost reduction effect by incorporating functions related to agricultural traceability and authentication, and the field server. A synergistic effect is produced by a combination with the above-mentioned functions of the device, and a new function that cannot be realized when each device is used alone can be realized.
A new function to be realized by the present invention is an agricultural product tracking system that realizes information acquisition and disclosure method of individual authenticity for prevention of substitution and fraud that cannot be realized by a conventional traceability system.

Patent Document 1 discloses a method for providing agricultural product identification information to an agricultural product as an agricultural product traceability system.
As a specific identifier in this case, generally, an RF-ID or a barcode is used. However, it is necessary to install an RF-ID reading / writing device or a barcode reader in the field.

  Especially on farms, the installation of precision equipment is waterproof, dustproof, and heat-resistant, and the installation of equipment is an obstacle to farm work. In addition, the cost required for wiring between devices is large, and there is a problem that the surrounding scenery is damaged when the equipment becomes large.

In Patent Document 2, data is obtained by continuously observing the installation environment of a large number of objects, and the data is concentrated in a short time at a low cost, so that a large number of objects at a small number of monitoring positions can be collected. An installation environment observation device that enables monitoring efficiently, an installation environment monitoring device, and a system that transmits information via a communication network are disclosed.

  In this invention, the data observed by the continuous observation means of the installed environment observation device is subjected to statistical analysis processing at regular time intervals, and an e-mail including the observed statistical data in the text is sent to the communication network, which is provided at a remote location. It was received and monitored by the installed environment observation equipment.

  However, the signal from the observation device provided in the continuous observation unit is connected to the A / D converter of the installation environment observation device, and it is necessary to install a large number of devices. In addition, processing such as data statistical processing was necessary.

That is, in order to solve the above-mentioned problem, the agricultural product tracking system of the present invention first copes with a method for preventing authentication fraud by the following method.
An identifier such as an RF-ID is assigned to a target article or person, and the biological information of the target is used as a pair of information for authentication. Furthermore, by utilizing the fact that biological information changes little by little with time, the change record is accumulated as time-series information and used as information for detecting misrepresentation. For example, scratches, colors and textures on the surface of agricultural products change little by little by growth and ripening. In the case of humans, the entire wound on the surface of the finger also changes little by little due to the occurrence of a new wound and the recovery of the wound. Therefore, when a person who intends to cheat presents a past hard copy, it may be discovered that it is not the present but the past by comparing with the accumulated past data. By showing this possibility, misrepresentation can be suppressed.

  In the case of agricultural products, even simple information such as the weight of agricultural products functions sufficiently as biological information. For example, the weight of fruits harvested in the field is slightly reduced by respiration and transpiration. Therefore, it cannot increase or decrease rapidly. Therefore, when the weight increases at a certain point in time at harvest, at the time of selection, at the time of retail, at home, etc., it can be determined that there is a high possibility that a change has occurred immediately before that point. However, misrepresentation is easy with weight alone. Therefore, in addition to weight, it is necessary to use a combination of size, shape, surface color, scratches, texture, and the like. Furthermore, by recording information on environmental conditions at the same time, it is possible to detect misrepresentation. For example, agricultural products stored in a low temperature and high humidity environment are less susceptible to wilting and weight loss than agricultural products stored in a high temperature and low humidity environment. Therefore, when there is a significant change in the texture of the surface of agricultural products stored in a low temperature and high humidity environment, there is a high possibility of misrepresentation. That is, the environmental information can be used as information that complements the biological information.

In addition, the agricultural product tracking system using the field server of the present invention collects at least weather observation data, cultivation environment data, and growth status image data at a plurality of points in the agricultural product cultivation field every predetermined time, and displays the cultivation status at each point.

There is an identifier such as an RF-ID or a two-dimensional barcode on the surface or packaging of the mandarin orange. From this identifier information, consumers can obtain detailed information such as the producer's name, face photo, production history, etc. via the Internet. . From the image information of the field server set up in the farm field, this producer learned that the citrus was grown in pesticide-free and organic cultivation. This is what a conventional traceability system can do.

  However, a consumer who heard the rumor that "Koshihikari from Uonuma has much more counterfeit than its production" is said to have been replaced by another orange on the way. I will have suspicion.

  At this time, the present invention functions as follows, and the consumer's anxiety can be resolved. In other words, the mandarin orange at hand is matched with the image taken when the producer packs it, looking for a piece with the exact same shape, and if there is no replacement, you can obtain a sense of security . If there is absolutely no identical shape, there is a possibility that a replacement has occurred, and it is confirmed with a photographed image in the middle of the distribution channel. In addition, it is possible to find out the person who has performed the replacement from information such as whether or not the person is approaching carelessly.

  Field server cameras can also record fine crop information. For this reason, the melon mesh, the mandarin oranges, the mottled pattern and sesame pattern on the surface of the apple, and the fine scratches, which are the individual identification information, are recorded together with the agricultural product identification information in real time. In addition, according to high-resolution imaging, it is possible to record RF-ID pasted information and high-resolution images up to the worker's face, clothes folds, and work machines (tractors, etc.), and the record can be stored in a remote server. Records can be stored safely in a state that cannot be tampered with.

  If the replacement of the agricultural product is suspected, the consumer himself or a specialist of a third-party certification organization such as NGO / NPO can check whether the replacement has been made based on the data of this image. Expert surveys can be conducted remotely over the Internet. This investigation can be carried out to prevent the replacement action.

  In addition, a two-dimensional bar code or code in which each URL address is recorded is attached to the field server, and the mobile phone that can decode the URL address is connected to the field server via the Internet, and the database in the field server is browsed. can do. In particular, if the field server places an unmanned agricultural product sales office under its management, a user of the unmanned sales office can make a purchase with such a mobile phone. In addition, it is possible to monitor unauthorized take-out by non-users and perform management to prevent theft.

According to the present invention, the following effects can be obtained. That is, in the conventional technology, it is very expensive to install a camera, a non-contact type tag (RF-ID) reader, a plurality of sensors and a communication system individually at each place, and an inexpensive product such as an agricultural product. It was difficult to apply. In addition, because the system becomes complex, breakdowns and inadequacy of maintenance are likely to occur, and it is difficult to distinguish from malicious acts such as damage to the system or sabotage by malicious persons, allowing easy destruction. become. In contrast, in the present invention, since all these functions are integrated in the field server, the number of man-hours required for installation can be greatly reduced. Moreover, since the apparatus is standardized and suitable for mass production and mass production, the cost of the apparatus can be greatly reduced.

  Furthermore, since it is only necessary to install a large number of identical field servers, the system can be quickly restored by simply replacing it in the event of a failure. Even if a malicious person makes an unauthorized modification to the field server device itself, it is easy to discover the action.

  Specifically, a plurality of field server groups each incorporating at least a non-contact RF-ID reading / writing unit and a wireless LAN transmitter / receiver are arranged in any field in a field by a field server network arranged at each point of an agricultural product cultivation field. Even if the agricultural product is harvested from the place, the agricultural product cultivation data and the enlarged image of the agricultural product, particularly the image that is characteristic of the agricultural product, are imaged and recorded and stored in the field server closest to the harvesting location. The record is transferred to the adjacent field server. Further, by attaching the RF-ID to the produce, the identification information in the RF-ID is also read by the first field server, and the RF-ID data is sequentially read by the adjacent recording means. , Since it is transferred to all other field servers, the recorded data and RF- It is possible to prevent the falsification of D data.

  The record data is automatically recorded every time when it passes through the transmission / reception distance range of the non-contact RF-ID reading / writing means of each field server after the agricultural products are first harvested by the field server group arranged at each point. And the RF-ID data is automatically compared and verified by the CPU of the field server, and if the probability of being rewritten is high, a warning is displayed and further written in the RF-ID. At that time, it is possible to investigate the presence or absence of replacement with an enlarged image including the shape and pattern of the agricultural product, and thus an efficient tracking system that minimizes manual work can be constructed.

  In addition, even if the field server network is outside the hotspot range, the agricultural product purchaser's mobile phone or a personal computer with a web browser is connected to the web server in the field server via the Internet, and various data relating to the agricultural product is obtained. And the image data can be read to easily confirm that the produce has not been “replaced” with the original data.

  Since the RF-ID read / write means incorporated in the field server disposed at each point forming the field server network can be configured as a single-purpose programmable module having a general purpose. The field server in can be set to a function corresponding to the point and can be effectively arranged.

  Moreover, if the RF-ID reading / writing means of a plurality of programmable modules are used, it becomes possible to simultaneously process a large number of agricultural products or transported items to which RF-IDs are attached at the same time.

  The field servers arranged at each point are classified into functions and stored in storage cases, and further, the storage cases are vertically mounted as necessary. Therefore, it is possible to easily install and maintain the field server. Further, by adopting a structure in which these storage cases are attached to a single support bar, the arrangement area can be minimized and installation work can be facilitated.

  Furthermore, the URL address is affixed to each field server using a two-dimensional bar code or code, and the database in the field server is browsed or managed by an unmanned sales office via the Internet using a mobile phone that can decode the address. Management can be performed.

  An embodiment of an agricultural product tracking system using the field server of the present invention will be described below in detail with reference to the drawings.

  FIG. 1 is a schematic diagram showing a network of field servers. In FIG. 1, reference numeral 10 denotes a field server having a standard configuration, and FIG. 2 is a schematic diagram showing the configuration of the field server 10 and the relationship with the RF-IDs 1, 2, and 3. Hereinafter, a description will be given with reference to FIGS. (The difference between RF-ID1 and RF-ID3 is shown in FIG.

  The field server 10 includes various sensors 10a for measuring production environment data, a meteorological observation instrument 10d, a video recording camera unit 10b with a 360 degree direction image mechanism (camera driving mechanism and video recording camera), and illumination with an electronic control switch. RF- consisting of an IC chip including a non-contact type carrier frequency microwave band resonance circuit affixed to a container 10c, a wireless LAN transmission / reception unit 10f capable of communicating with an adjacent field server, a Web server 10l connected thereto, an agricultural product or its storage case The RF-ID reading / writing means 10i capable of communicating with the ID, the data from the observation instrument 10d and the various sensors 10a are stored and controlled, and the camera unit 10b, the illumination unit 10c, and the RF-ID reading / writing means 10i are controlled. Information recording means server 10g and their data and agricultural product management program A hard disk drive which manages various databases group consisting beam and (HDD) (also hereinafter database subjecting a storage device the same sign) storage device 10j such as, at least consisting of those of the power supply circuit unit 10h. The power supply circuit unit 10h is connected to any of a solar panel, a 100V AC power supply, and a 12V battery.

  The information recording unit server 10g includes at least an RF-ID reading / writing unit, an update data adjacent transfer unit, and an RF-ID collating unit. The function of each means will be described below.

  The RF-ID read / write means is provided in the application server 10g of each field server 10, and causes the RF-ID read / write means 10i to transmit a communication carrier wave, which is affixed to the produce or its storage case. When the RF-ID 3 enters the communicable distance range, the RF-ID 3 data is immediately read and recorded in the database 10j, and if necessary, the data is written into the RF-ID 3.

  The update data adjacent transfer means automatically transfers the measurement data, the image data, and the RF-ID data to the adjacent field server every time data recorded in the database 10j is updated, and the adjacent field server database 10j. Is a means for recording.

  The RF-ID collating means reads the RF-ID data from the first field server when the farm product on which the RF-ID is pasted and the recorded data is transported / moved. The transfer-recorded RF-ID identification information is searched, and the RF-ID data and image data are collated on the working memory. If they match, the identification data is “no replacement”. Is recorded in the database 10j and written in the RF-ID, and when there is a discrepancy, a warning of “with replacement” is displayed on the display unit of the field server 10 and / or a warning sound is emitted.

  This RF-ID collating means includes the harvested and collected agricultural products or the RF-ID3 attached to the storage case within the communicable distance range of the RF-ID (shown as a dotted circle in FIG. 1). At this time, the record of the first field server that has read the data is sequentially recorded in the database 10j of all the field servers 10 in the network 100 by the update data adjacent transfer means, so that collation is possible. .

Further, the application server 10g can further store an enlarged image of agricultural products around the site or an image obtained by the electronic control camera 10p with a microscope added via the HUB or the like and store it in the database 10j.

  A field server 10-1 in FIGS. 1 and 2 is a field server installed in, for example, a greenhouse or a greenhouse, which is blocked from outside air by a protective sheet or the like. Such a field server may have a different power source and meteorological observation equipment configuration from a standard field server installed outdoors. Moreover, you may put a camera part in the same storage case as an illuminator.

  The field server 10-2 indicates a field server installed at a high place such as on a hill, a mountain peak, or a balloon. The field server installed under such conditions may be provided with only the wireless LAN transmission / reception unit 10f to perform only the wireless relay function. As the power supply unit 10h, a combination of a solar cell and a battery is desirable.

  The field server 10-3 is a field server provided with a broadband line connection unit including a modem connected to the Internet and the communication line network 150. This field server has a function of reading agricultural product data, image data, and RF-ID data from the database 10j and transmitting them to the computer system 200 in response to access from the computer system 200 of the central management office via the Internet. . That is, according to this field server 10-3, it is possible to collect data by controlling each field server at the central management office.

  In FIG. 1 and FIG. 2, a broken line indicates a wireless relay line using a wireless LAN. The circles in FIG. 1 indicate the arrangement positions of the field servers 10, 10-1, 10-2, and 10-3, and the solid circles shown on the outside of the circle indicate the ranges in which each field server performs agricultural product cultivation management (hot Spot).

  A circle indicated by a dotted line is a read distance range of RF-ID 1 or 3 by the non-contact RF-ID read / write means 10 i. The circuit of RF-ID3 includes an integrated resonance circuit in the microwave band, and there are many IC circuits whose carrier frequency is designed in the microwave band.

  If the agricultural product or the storage case to which the RF-ID 3 is attached passes through the circle indicated by the dotted line, the field server 10 at the center of the agricultural product or the storage case is automatically assigned to the RF-ID 3 by the RF-ID reading / writing means. Next, each field server 10 compares with the first RF-ID data in the database 10j by the RF-ID collating means, records the comparison result, and the data is sent by the update data adjacent transferring means. Transfer to nearby field servers.

  When the end user purchases agricultural products harvested in the field server network outside the range of the field server network 100, the consumer uses the Internet 150 from his / her mobile phone 300 or a personal computer 400 equipped with a Web browser. To the field server 10-3, and the RF-ID data accumulated therein can be collated with the agricultural products currently purchased by the user. Moreover, it can collate from RF-ID2 provided with the web browser.

  When the collation is performed, the video recording camera unit 10b of the field server 10 may further include an electronic control camera 10p including a microscope lens that acquires an enlarged image, and may record a digital image of a fine structure.

  The application server 10g of each field server 10 causes the RF-ID read / write means 10i to execute the RF-ID read / write means, and in addition, immediately after the execution (a time immediately after the agricultural product cannot be “replaced”) (In), if the shape of the agricultural product and the enlarged image including the pattern by the electronic control camera 10p are recorded at a predetermined enlargement ratio (enlarged image recording means), and the collation by the RF-ID collating means is matched, Next, the image is compared with the enlarged image of the agricultural product, and if there is a difference, the image is identified as “enlarged image replacement” and displayed on the display unit, and the image collating means for recording the data in the database 10j; Enlarged image adjacent recording means for transferring in the same manner as the update data adjacent transfer means.

  That is, the identification data indicating whether or not the enlarged image is replaced is also transferred to the field server of the entire network 100 by the above means.

It is to be noted that, in the image matching means, the identity determination between the enlarged image at the field server at each point and the enlarged image data acquired at the field server at the first harvest point is automatically performed by a predetermined pattern recognition program. A determination unit and a display data unit thereof;
Only when the pattern matching rate by the program is lower than a predetermined rate, a display image that is determined to be determined with the naked eye is output to the display unit, and automatic determination is performed efficiently, and automatic determination is difficult Only ask for a naked eye check and perform efficient operation of judgment work.

  As shown in FIG. 2, if RF-ID 2 is an IC circuit having at least a Web browser and a transmission button to the field server, the field server 10-is connected via the Internet 150 from the RF-ID 2 attached to the agricultural product. It is possible to directly collate with the data of the agricultural products in 3.

  In FIG. 3, the non-contact RF-ID reading / writing means 10i provided as standard in the field server 10 is a programmable module 80 of a single device.

  The programmable module 80 is provided with a transmission / reception circuit that communicates with the RF-ID 3 attached to the agricultural product. In response to the command signal from the application server 10g, the carrier wave modulated by the signal is transmitted from the antenna i.

  On the other hand, if the RF-ID 3 falls within the reception distance range of the carrier wave, the carrier frequency resonates with the resonance circuit in the RF-ID 3 IC circuit, that is, the RF-ID 3 receives the modulated carrier wave. Then, it demodulates and reads the data of the application server 10g and receives the command signal. Data in the RF-ID 3 is returned based on the command signal.

  Next, the configuration of the programmable module 80 will be described with reference to FIG. Corresponding to the use conditions of RF-ID3, the versatile single-device programmable module 80 is composed of the following four circuit elements.

  That is, (1) a digital synthesizer 81 that outputs a frequency composite waveform signal wave by a first program input, (2) a multiplier 82 that inputs two input voltages and outputs the product of them as a voltage, and (3) an operational amplifier FPAA (Field Programmable Analog Array) 83 comprising a plurality of electronic circuit basic elements including at least resistors and capacitors, and elements whose constants and connection selection can be changed by a second program input.

  (4) The computer section 84a for controlling the whole including the digital synthesizer 81, the multiplier 82, and the FPAA (field programmable analog array) 83, the DA converter 84x, and the first and second programs are digitalized. It comprises an FPGA (Field Programmable Gate Array) 84 having programmable equipment that outputs command signals via buses 84p and 84q.

  The FPAA 83 has output / input terminals 83a and 83b for outputting a transmission signal to the RF-ID 3 to be read / written via an antenna and receiving and inputting a response signal from the RF-ID 3 via the antenna. Prepare.

  As the antenna i for transmission / reception, a conventional technique for separating an electromagnetic wave input or output from the antenna with a directional coupler or the like can be used.

  The computer unit 84a of the FPGA 84 includes recombination means for recombining the selection for activating the wiring between the four circuit elements 81 to 84 by the third program via the digital buses 84p and 84q.

  The four circuit elements 81 to 84 are connected to the DC power supply of the DC-DC converter 85, respectively.

  The non-contact RF-ID reading / writing means 10i (programmable module 80) having the above configuration receives the communication start signal command with the RF-ID from the agricultural product management application server 10g shown in FIG. Thus, an electromagnetic wave is emitted from the output terminal 83a to the periphery via the antenna i.

  First, the computer unit 84a activates the wirings 86, 87, 87a, 88 between the four circuit elements 81 to 84 so as to meet the conditions for enabling the communication with the RF-ID 3 by starting the third program. To do.

  Next, the computer unit 84a activates the first program and communicates with the RF-ID 3, so that a voltage wave for a carrier wave corresponding to the resonance frequency band of the RF-ID is generated by the digital synthesizer 81 and wired. Output to 86.

  Next, the command signal data of the computer unit 84 a of the FPGA 84 is input as a modulated voltage wave by the DA converter 84 x to the multiplier 82 via the wiring 87, and a product with the digital synthesizer 81 is generated and the FPAA 83 is generated via the wiring 88. Output to.

  When the computer unit 84a receives a signal via the digital bus 84q that the FPAA 83 has received the modulated carrier voltage from the wiring 88, the computer unit 84a starts the second program.

  The second program determines the connection and element constant of each element of the FPAA 83 so as to correspond to the modulation carrier transmission circuit and the reception circuit for detecting the reception carrier, and emits the modulation carrier from the antenna.

  Next, if RF-ID3 is within the reception distance range of the carrier wave (usually a microwave band), RF-ID3 responds to the carrier wave and transmits an electromagnetic wave modulated by data in the RF-ID internal memory. Receive by antenna i. The received carrier wave is detected by the receiving circuit in the FPAA 83, and the detected output enters the AD converter 84y via the wiring 87a, is converted into a digital signal, and is read into the hand computer unit 84a.

  If necessary, the programmable module 80 (10i) can perform a writing process in response to a command according to a predetermined program procedure in the application server 10g.

  As described above, a plurality of RF-ID reading / writing means 10i of the programmable module 80 of a single device whose configuration has been described are connected via a LAN, a HUB, etc., and a plurality of RF-IDs 3 in an integrated storage container or a transport vehicle are connected. A group may be read and written by simultaneous parallel processing. As a result, even when a large number of agricultural products to which RF-IDs are affixed are stacked, it is possible to provide a system capable of sequentially reading and writing in the loaded state in a short time.

  Next, the application server 10g that explains the operation of the application server 10g of the field server 10 transmits a modulated carrier wave so that each of the programmable modules 80 under control can communicate with one of the RF-ID groups. Let

  Each module 80 communicates with the RF-ID 3 that has first entered the transmission / reception range, and sends the read result data to the application server 10 g. The application server 10 g stores and records the data for each RF-ID in the database. .

  In response to a command from the application server 10g, the module 80 receives the received signal from the RF-ID 3 that is next within the transmittable / receivable range, performs the same processing, and receives another RF-ID 3 during the receiving processing of the module 80. Selection means not accepting.

  A plurality of modules 80 can sequentially process a large number of RF-ID3 reading and writing processes simultaneously. That is, it is possible to provide a system having a feature that allows efficient reading in a short time.

  FIG. 4 is a schematic diagram showing the structure of the field server according to one embodiment of the present invention, and shows the structure of the field server stacked in the vertical direction on the ground. In this embodiment, the installation area is small, the maintenance is easy, and the configuration can be easily recombined.

The field server 10 is accommodated in a storage case as the following five classifications.
(1) Meteorological observation instrument 10a
(2) Video recording camera 10b with 360 ° ambient image mechanism
(3) Electronically controlled ON / OFF lighting fixture 10c
(4) Various sensors 10d, Web server 10e, wireless LAN transceiver 10f,
Application server 10g, RF-ID reading / writing means 10i, storage device 10j such as HDD
(5) Power supply unit 10h

  Said (1)-(5) is accommodated in the five storage cases to each store, and each unit of (1)-(5) is made into one assembly basic unit.

  Further, the units (1) to (5) are stacked in a direction perpendicular to the ground.

  The field server 10 freely selects a storage case for each assembly unit according to the required specifications, and sets it as a field server having a necessary function.

  The storage case of each assembly basic unit of (1) to (5) has a structure in which the structure of the joint portion between the upper surface and the lower surface is a coupling mechanism using the same shape, size, or screw to facilitate assembly.

  In addition, the storage case of each assembly basic unit is provided with a hole through the hollow bar at the center or sandwiching the hollow bar, and the selected storage cases are embedded from the ground into the ground in any order. Easy to insert into a single pole hollow rod and fix and stack. Therefore, removal and replacement can be easily performed, and the installation area can be reduced.

  In FIG. 4, the solar cell power supply unit 10 h (5) is mounted on the hollow pole 12 on a frame fixed from below, and then the camera unit 10 b (2) made of a transparent cylindrical member is mounted on the fixed frame. To do. The inside of the hollow portion of the hollow pole 12 can be used as an installation space for power supply wiring.

  Next, the observing device 10a (1) housed in the net is mounted with the frame fixed thereon. Furthermore, a gantry is fixed on it, and the illuminator 10c (3) accommodated in the transparent cylindrical member is mounted.

  A base is fixed to the hollow pole 12 on the upper side, and various sensors 10d, a Web server 10e, a wireless LAN 10f, an application server 10g, an RF-ID reading / writing means 10i, a database device 10j (4), etc. are accommodated and mounted in a transparent cylinder. To do. Further, an uppermost lid 11 is provided thereon, and various sensors 10d are arranged.

  Next, referring to FIG. 1, the tracking of harvested agricultural products will be described. Also, so-called anti-falsification tracking where agricultural products harvested at a certain place in the field are “replaced” with other agricultural products in the process of moving from the production site to the store where they are sold. The specific operation of the system will be described.

  Suppose that agricultural products are harvested at any of the hot spots (indicated by a hatched circular range centering on the field server in FIG. 1) that is the agricultural product cultivation management range of the field server 10 shown in FIG. Let that place be the first point.

  At the first point, RF-ID3 is affixed to the harvested agricultural product or its harvesting container. Next, the farm products or storage containers are accumulated within the RF-ID readable distance range (indicated by a circular broken line in FIG. 1) of the field server 10 that manages the first point, and communication with the RF-ID 3 is performed. To start.

  That is, the application 10g of the field server 10 instructs the RF-ID read / write means 10i to communicate with the RF-ID3, and the RF-ID read / write means 10i transmits a carrier wave from the antenna i at predetermined time intervals. When the RF-ID 3 enters the readable range, it immediately receives the response carrier wave and starts communication, reads the RF-ID 3 data and writes the data related to the harvested agricultural products. Recorded in the database 10j of the application server 10g as the first harvested agricultural product data at one point. (RF-ID reading / writing means)

  The first harvested agricultural product data at the first point is automatically recorded sequentially in the database 10j of all field servers 10 in the network 10. (Update data adjacent transfer means)

  On the other hand, when the agricultural product with the RF-ID 3 attached or the storage case thereof is transported and transported for sale, the field server is automatically in the center whenever the RF-ID 3 passes through the dotted circle in FIG. 10, the data related to the RF-ID 3 is updated, and the verification result data is written in the database 10 j and the RF-ID 3 each time. (RF-ID verification means)

  Therefore, a consumer of agricultural products can confirm whether the agricultural products have been replaced from the mobile phone 300, the personal computer 400, and the RF-ID 2 having the Web browser not only within the network 100 but also outside the network 100. it can.

  The present invention, which can detect the change by using the combination of the unique information by the enlarged image of the agricultural product and the identification information by the RF-ID through the Internet, is a kind of agricultural product that is made of biological materials such as leather tortoiseshell products Can be managed as For example, suppose there is a luxury brand handbag that is given an identifier such as an RF-ID or serial number along with the brand name. When an identifier peeled off from a used route or a waste product is affixed to a fake handbag and put on the market, it is identified as genuine by a conventional traceability system. However, in the present invention, an image of a part or the whole of the handbag is stored in a remote server at an enlargement rate that allows fine wrinkles to be identified, and is distinguished from such a fake by matching with this image. I can do it.

  FIG. 5 is an explanatory diagram showing a method for reading RF-ID 3 corresponding to a wireless LAN from the mobile phone 300 via the Internet 150.

  If the wireless LAN compatible RF-ID3 is within the hot spot range formed by the field server 10, the data can be read and accessed via the Internet using a mobile phone, a personal computer, a PDA, or the like. That is, access is made to the wireless LAN-compatible RF-ID3 (IC card having a client function that can be connected to a wireless LAN access point) data in the hot spot, and the attribute information and history information of articles such as agricultural products are read or permitted. You can also write.

  FIG. 7 is an explanatory diagram showing a method of reading from the RF-ID. (1) is in the vicinity of the field server, (2) is a ring-shaped loop coil, and (3) is a tunnel-shaped loop coil. The case where is used is shown.

  FIG. 7 (1) shows the case of RF-ID3 compatible with wireless LAN, and the RF-ID3 data attached to the agricultural products and cases near the field server 10 by the non-contact RF-ID reading / writing device 10i of the field server 10. Is a way to access. The accessible range in this case depends on the electric field strength of a radio (for example, microwave band) carrier wave emitted from the antenna of the RF-ID reading / writing means 10i, but communication can be performed even naturally farther than the coil type shown below.

  FIG. 7 (2) shows that RF-ID1 is provided with a transmission line from the RF-ID reading / writing means 10i in the field server, and a ring-shaped loop coil is connected. In this method, data communication is performed by coupling an electromagnetic field and a coil in RF-ID1.

  In FIG. 7 (3), the coil is a tunnel-like loop coil. This is the same as the coupling method of FIG.

  FIG. 6 is an explanatory diagram of the agricultural product image, the flow of the data, and the collation process by visual observation. Based on FIG. 6, the flow of the image data of the agricultural products 4 and the related data and the process of collating those data with the personal computer 400 etc. via the Internet will be described.

  Here, reference numeral 200 denotes a database server that accumulates information of each field server 10 collected by the central office computer system. The server 200 stores all the images and data in the field server 10 that have passed when moving from the image data in the field server 10 from which the agricultural products 4 are harvested.

  The user can visually compare the agricultural product 4 that is currently purchased with the image recording content of the server 200 via the Internet using the personal computer 400.

  Of course, as described above, each field server 10 automatically collates a predetermined pattern item each time an image of the agricultural product 4 is imaged at the passing point, and the matching rate is determined based on a predetermined rate. The low image is displayed to that effect, and is processed efficiently by the automatic matching function. According to the present invention, visual observation is finally possible via the Internet at the site where the agricultural product is located or away from the site.

  Next, a description will be given of a case where a two-dimensional bar code or a two-dimensional graphic code in which a URL address is recorded is attached (pasted) in advance to each field server 10 on each surface, for example, the side surface of the hollow pole 12. To do.

  The application server 10g of each field server 10 includes the following program means.

  When an access by the URL address is received from a mobile phone having a program capable of decoding and decoding the URL address pattern of the two-dimensional barcode or code, the user ID number or password sent from the mobile phone and the database A user ID means or a password registered in advance is checked each time, and if they match, a user authentication means for authenticating the user,

  Data browsing permission means for granting permission to the authenticated user to browse measurement data related to various agricultural product management and a database storing image / RF-ID data.

  In addition, when there are unmanned agricultural product sales offices to be managed in the hot spots of the field servers 10, the application server 10g of the field server 10 indicates that the access request content from the authenticated user is the selection of the agricultural product purchase. In such a case, there is provided an agricultural product purchase billing means for allowing the purchase price and quantity to be selected, permitting the purchase, and recording the agricultural product transaction settlement information in the database.

  Further, the application server 10g does not execute the program of the user authentication means and the produce purchase billing means, and the RF-ID read / write device 10i is attached to the produce at the produce sales office. When the movement of ID3 is detected and the detection result is received by the application server 10g, an alarm for taking out without permission is displayed on the display device, an alarm sound is output, and a security company designated in advance via the Internet It is provided with an unauthorized agricultural product movement warning means to notify the notification destination.
