Description

  The present invention provides a wireless communication medium processing system capable of preventing a reading error and reliably confirming in a system such as automatic inspection or automatic checkout of articles using a wireless communication medium such as a non-contact IC card or an IC tag. The purpose is to provide.

  A wireless communication medium having an ID code, such as an IC card or an IC tag, and a wireless communication medium processing apparatus for performing ID code authentication of the wireless communication medium are used for authentication, baggage destination distribution, and the like. It is increasing. When the communication mounted medium exists in the communication range of the communication mounted medium processing apparatus, an induced voltage is generated in the antenna of the wireless communication medium by electromagnetic waves from the antenna, and this voltage is rectified to supply power and transmission data. In a wireless communication medium to which power is supplied, according to data read from the mounted memory, for example, in a modulation circuit composed of a load resistor and a switch connected to an antenna, according to data 1 and 0 The switch is turned on and off. With this on / off, a load variation occurs on the antenna of the wireless communication medium, and this load variation is transmitted as a signal to the antenna on the communication medium processing apparatus side. The transmitted signal is demodulated and its ID code authentication is performed (see, for example, Patent Document 1).

In this way, processing such as attaching low-cost IC tags or other wireless communication media to goods or packages and performing simple inspections at airport customs clearance or clearing a large number of goods at a store etc. Development of a system is underway (see, for example, Patent Document 2). These are performed using acquisition of an ID code from a wireless communication medium.
JP 2000-163523 A JP 2001-289705 A

  However, when the products with the wireless communication medium are collectively cleared, there is a problem in the reliability not only that the reading mistake does not occur. Alternatively, in the inspection at customs clearance, securing reliability due to the possibility of reading errors has been a problem.

  If there is no efficient and simple means to prevent these reading mistakes or check the reading mistakes, even if a wireless communication medium such as an IC tag is attached to a product, etc., management and settlement will be performed collectively. It cannot be automated and the utilization of wireless communication media is insufficient. This is because, as long as there is a possibility of reading errors, it is necessary to perform an inefficient operation of checking each product by human means. If it is not known that a reading error has occurred at this time, there is also a problem that an unbearable situation such as re-inspecting all items and re-checking occurs after a large amount of processing is completed.

  In (Patent Document 2), in order to solve these problems, an ID code and weight information are stored in an IC tag, and at the same time, these are read by a reader / writer, and at the same time, a weight is physically measured, By comparing these, the presence or absence of unread is checked.

However, when all of the ID code and weight information are stored in the IC tag and read, it is necessary to first perform a procedure in which the reader / writer reads the ID code from the IC tag. Next, it is necessary to write a command for outputting weight information to each IC tag according to the ID code. Next, a procedure of at least three steps of reading weight information from the IC tag is required between the IC tag and the reader / writer.

  This is because the start position and end position of a bit stream used for reading a normal IC tag or the like are not clear, and the same bit stream is repeatedly responded to the reader / writer. This is because a plurality of types of data (for example, two of ID code and weight information) cannot be acquired. If this is realized, it is necessary to store the bit stream output from the IC tag or the like in a very complicated configuration and store a plurality of types of data in one bit stream. It is necessary to greatly complicate the procedure of interaction with the. Error correction is also required, the circuit load becomes large, power is given by the magnetic field originally generated by the reader / writer, and data is sent back by mutual inductance with the IC tag etc. Therefore, it is not suitable for wireless communication medium processing considering the spread by reducing its cost.

  For example, in the case of developing not only weight information but also various information such as price and product characteristics to automatic settlement and automatic inspection, an extra procedure is required, and a low-cost wireless communication medium and its processing are required. There is a problem that the apparatus and the processing system cannot be configured.

  In addition, since the ID code is rarely changed, the weight information and price information may be changed. Therefore, in a system that needs to store all of them in a wireless communication medium, every time the ID code is changed. It is necessary to rewrite the memory of the wireless communication medium, which is troublesome and may cause a processing error.

  In view of the above problems, the present invention can easily cope with various future changes while ensuring a low-cost and simple processing procedure, and prevents reading errors or promptly detects reading errors. It is an object of the present invention to provide a wireless communication medium processing system that realizes automatic settlement of a large number of articles and automatic inspection.

  According to the configuration of the present invention, by acquiring only ID codes from a wireless communication medium such as an IC tag and separately storing weight information and price information corresponding to these ID codes in a storage table, Information can be recognized without placing an extra burden on a wireless communication medium, a read / write unit, or the like. For this reason, since a low-cost and highly reliable processing system using a low-cost wireless communication medium or a read / write unit can be constructed, it can be easily spread.

  In addition, even when various information needs to be changed or updated later, it is not necessary to rewrite the memory of the wireless communication medium individually, and only a batch update of the information table is required, so that the work load is reduced, and the wireless communication medium The amount of memory can be reduced, and the cost can be reduced. Furthermore, it is possible to construct a user-friendly system with high maintainability.

Also, the ID code is read from the wireless communication medium, the weight information corresponding to the ID code is obtained from the information table, the weight of the article (total weight) is calculated, and the physically measured weight (total By comparing (weight), it is possible to immediately detect reading errors and unreading of the wireless communication media attached to the items being read, so it is possible to automatically inspect many items at once. It becomes. These are realized by a simple configuration without adding new hardware and software to the wireless communication medium and its read / write unit.

  Also, by storing the price information corresponding to the ID code in the information table, it is possible to automatically liquidate a large number of products. Furthermore, by storing the product information, It is also possible to automatically check the inventory, and even in such a case, an unread or read error can be immediately detected on the spot, so that a highly reliable system can be constructed. Of course, it is possible to avoid inefficient work such as searching for a reading mistake after the fact.

  In addition, a user-friendly system can be realized by notifying the user of the presence or absence of abnormality.

  In addition, when a reading error is detected, automatic re-reading does not require an extra effort for the operator, and automatic inspection and automatic check-out are surely executed to the end.

  Furthermore, by using a structure in which an antenna is arranged inside a box shape or a shelf shape, and checking an article with a wireless communication medium attached thereto, for example, a shopping basket at a cash register in a store It is possible to realize an automatic settlement system with no reading mistakes by simply placing it.

A command unit, 19 is a price clearing unit, 20 is a price display unit, and 21 is a cash register device.

  First, details of each part will be described.

  The wireless communication medium 1 is a medium that communicates with the read / write unit 5 in a non-contact manner, such as an IC tag, an IC card, an ID tag, an identification label, and an RF-ID tag. Yes. The wireless communication medium 1 is equipped with a memory, and an ID code uniquely assigned to each type of article is stored in the memory. The read / write unit 5 communicates with the wireless communication medium 1. Thus, the ID code can be read out.

Further, the wireless communication medium 1 is equipped with a built-in antenna in addition to a memory, an IC, and the like. When a magnetic field generated from the antenna 3 is received, induced power is generated in the built-in antenna and is incorporated into the wireless communication medium 1. Electric power is supplied to the ICs and the like. In the wireless communication medium to which power is supplied, a load fluctuation occurs in a modulation circuit including a switch and a load circuit according to data from the mounted memory, and this load fluctuation is transmitted to the antenna 3 by mutual inductance. The antenna 3 receives this load variation as a signal and transmits it as a received signal to the read / write unit 5. The read / write unit 5 demodulates this signal, performs error detection as necessary, analyzes the signal from the wireless communication medium 1, and reads the ID code 6.

  The antenna 3 has a role of giving a magnetic field to the wireless communication medium 1 and can apply a magnetic field to all the wireless communication media 1 attached to the article 2 mounted on the weight measuring unit 4. Has communication range.

  The weight measuring unit 4 measures the total weight of the article 2. A normal weighing scale or the like is used, and an antenna 3 capable of applying a magnetic field to the wireless communication medium 1 is disposed at a site where the article 2 is mounted. In addition, the measurement result of the weight measurement unit 4 is output to the host 9 from the display unit that is displayed so as to be visible to the user, and the measured weight result is output from the measurement result output unit 7. The weight result output to the host 9 is temporarily held in the host 9 as a measured weight result and displayed on a display unit or the like as necessary.

  The weight result display unit may be shared with the display unit of the host 9, may be displayed on the weight measurement unit 4, or may be displayed on the display unit of the peripheral device of the host 9. .

  Further, the measurement result output unit 7 may output the measured weight to the host 9 as an electric signal, or may be output by other means.

  The read / write unit 5 communicates with the wireless communication medium 1 via the antenna 3. As described above, the read / write unit 5 supplies current to the antenna 3, and a magnetic field is generated from the antenna 3 to which the current is supplied. The read / write unit 5 demodulates the signal received from the wireless communication medium 1. Demodulation is performed on a signal modulated by a modulation method such as frequency modulation, phase modulation, and amplitude modulation. If necessary, error detection such as cyclic code check (hereinafter referred to as “CRC”), Reed-Solomon Error correction by Viterbi decoding or the like is performed. As a result, the ID code 6 is demodulated, and the demodulated ID code is transmitted to the host 9 via the relay station 8.

  The relay station 8 multiplexes the weight result in the weight measuring unit 4 and the ID code 6 in the read / write unit 5 and transmits the multiplexed result to the host 9.

  The host internal 10 includes an information table 11, an information extraction unit 12, a weight comparison unit 13, and a notification unit 14, which may be configured by hardware such as a dedicated device or circuit, or by software. It may be configured. Moreover, it may be mixed so that a part is hardware and the rest is software. In addition, there is an advantage that high-speed processing is possible by configuring with a dedicated LSI or the like. The information table 11 is also preferably stored in an external memory such as a so-called CD-ROM or DVD-ROM in preparation for a subsequent update.

  The information table 11 stores an ID code and weight information for each article corresponding to the ID code. Further, as described later, it is also preferable to store price information, and product information such as product type, expiration date, and production location. By storing a variety of these pieces of information, various automatic article management processes can be performed.

  The information extraction unit 12 extracts weight information and the like corresponding to the ID code from the information table 11.

  Further, the weight information extracted by the information extraction unit 12 is calculated for the article 2 and output through the extraction result output unit 12b. The output calculation result is temporarily held in the host 9 and stored together with the output from the measurement result output unit 7 in the host 9. Of course, it may be stored in an external storage medium. In addition, since the calculation result is processed and output inside the host 9, it is displayed on the display unit of the host 9. Or you may display on the display part of peripheral devices other than this.

  As described above, first, the weight measurement unit 4 outputs the measurement result through the measurement result output unit 7, and the weight calculation result extracted and calculated from the information table 11 through the ID code is output through the extraction result output unit 12b. . For example, weight values are displayed side by side on the display. Thereby, the user can easily recognize the weight, and can recognize the difference, difference, or coincidence of the weight by visual recognition. This may be a visual display or an audio display. For this reason, if it is a simple system, the comparison of a weight etc. can be performed by human work, without requiring the comparison means etc. which are mentioned later. Of course, it is also possible to approximate the difference in weight, and it is possible to confirm that a reading error or the like has occurred when there is a mismatch. Of course, by making all automatic by the weight comparison unit 13 and the notification means 14 described below, it is possible to save labor and to construct a lower-cost system.

  The weight comparing unit 13 compares the weight of the article physically measured by the weight measuring unit 4 with the total calculated value of the weight corresponding to the ID code extracted from the information table 11. As a result of the comparison, the weights match and the mismatches are transmitted to the notification means 14. The notification means 14 notifies the user of the result in accordance with the match or mismatch. For example, a blue LED emits light when they match, and a red LED emits light when they do not match. Alternatively, the user can be notified of whether a match or mismatch is immediately identified by various means such as voice and image display.

  Moreover, the range as a judgment criterion for coincidence may be set as appropriate depending on the type of the target article 2. For example, one having a very small weight needs to increase the accuracy range. If the weight of the key is large, such as 1 KG, an error of about several tens of grams may be included in the range of coincidence recognition.

  Here, whether the wireless communication medium 1 is read or not read is determined based on the match or mismatch of the weights. For example, if there are 10 articles and the total weight of the 10 pieces is 100 g as a result of measurement by the weight measuring unit 4 and the total calculated value of the weight information extracted from the 10 ID codes is 100 g. All the wireless communication media 1 of the articles existing there are read by the read / write unit 5. In this case, it is determined that no reading mistake or unread has occurred.

  On the other hand, when the weight measured by the weight measuring unit 4 is 100 g but the total value extracted from the information table 11 based on the ID code and calculated is 90 g, unread wireless communication Either the medium 1 exists or there is a reading error. For this reason, in such a case, it is necessary to perform reading again.

  It should be noted that a part for performing each processing in the host internal 10 may be included in another device or device other than the host 9, may be processed by a dedicated device or a dedicated circuit, or processed by software in the host 9. May be. The host 9 may be an electronic device such as a single computer, but may be a group of devices that are distributed over a plurality of devices via a network. The processing unit, the display unit, and the like may be physically dispersed and arranged.

  In FIG. 1, the antenna 3 and the read / write unit 5 are configured separately, and the antenna 3 is disposed on the article mounting unit of the weight measuring unit 4. However, as illustrated in FIG. 2, the internal space and the external space are separated. A case in which an antenna 3 and a read / write unit 5 are arranged inside a structure such as a box-like body or a shelf-like body having an opening to be connected will be described with reference to FIG.

  The structure 15 is a box-like body or a shelf-like body, and has an opening in a part thereof. Further, there is an internal space inside, and the article 2 with the wireless communication medium 1 is placed in this internal space for processing. The antenna 3 is disposed in the structure 15 and exerts a magnetic field on all of the X axis, the Y axis, and the Z axis that are orthogonal to each other in the internal space, and the magnetic field is applied to all the wireless communication media 1 existing in the internal space. Is being able to be granted.

  In this way, a magnetic field is applied to all of the wireless communication media 1 existing in the internal space, and the weight is measured using the structure 15 that is capable of communication, and at the same time, reading and writing with the wireless communication media 1 are performed. Thus, it is possible to confirm occurrence of reading mistakes or non-reading by weight comparison. In addition, by using the structure 15 that can communicate with all of the wireless communication media 1 existing in the internal space, the structure 15 is applied as an article box or the like, thereby making it possible to easily manage products automatically and automatically. It can be carried out. For example, with the structure 15 as a product basket, the products with the wireless communication medium 1 are put together in the product basket, and the physical weight of the product is compared with the calculated weight from the ID code. This prevents reading errors and ultimately realizes automatic inventory management and automatic price calculation.

  The read / write unit 5 may be integrated with the structure 15 or may be separate.

  FIG. 3 shows such a structure 15. The antenna 3 may be embedded inside the wall material of the structure 15 or may be disposed inside. It is also preferable to shield the outer surface of the structure 15 to prevent electromagnetic wave leakage. Further, the structure 15 may be any of a polygonal shape in addition to a rectangular parallelepiped shape and a cubic shape.

  Here, when the antenna 3 is stored in the structure 15, in order to apply a magnetic field to all the wireless communication media 1 existing in the internal space of the structure 15, the X axis and Y axis orthogonal to each other are provided. An antenna that generates a magnetic field with respect to all of the axes and the Z-axis is preferable.

  4 and 5 show the antenna 3 housed in the structure 15.

  The conductor 16 of the antenna 3 is formed along all of the X-axis, Y-axis, and Z-axis, and a magnetic field is generated in each of these conductors. As a result, the magnetic field HX and Y-axis along the X-axis All of the magnetic field HY along and the magnetic field HZ along the Z axis are generated. As a result, a magnetic field is applied regardless of the position and orientation of the wireless communication medium 1 existing in the internal space.

  Next, a processing procedure for detecting a reading error or non-reading of the wireless communication medium 1 based on the above weight comparison will be described with reference to a processing flowchart of FIG.

The process is started from the start (ST1), and the article 2 attached with the wireless communication medium 1 is mounted on the weight measuring unit 4 (ST2). Next, the total weight of the article 2 mounted by the weight measuring unit 4 is measured, and the measurement result is notified to the host 9 (ST3). Next, in the read / write unit 5, communication with the wireless communication medium 1 is executed, and the ID code 6 of the wireless communication medium 1 is recognized and notified to the host 9 (ST4). Based on the notified ID code 6, weight information is extracted from the information table 11, and the total weight is calculated (ST5). In response, the physically measured weight and the calculated weight are compared (ST6).
If the result of 4 is not coincident with the coincidence, the user is informed of the disagreement (ST7). If there is a mismatch, a message to the effect of the mismatch is transmitted to the inside of the process (ST8), and reading / writing and weight measurement of the wireless communication medium 1 are performed again as necessary. If everything is finished, it is finished (ST9).

  As described above, the weight is physically measured, and the ID code is recognized by communication with the wireless communication medium 1 attached to the article, and compared with the calculated weight from the information table. It is possible to immediately determine whether the communication medium is read or not read.

  Further, unlike the conventional method, since only the ID code is stored in the wireless communication medium 1, no extra storage area is required, and information such as weight, product number, and price that can be changed frequently other than the ID code. This update is simple and efficient by simply updating the information table included in the host. Further, it is not necessary to exchange with the wireless communication medium 1 many times, and it is not necessary to set extra circuits and program processing in the read / write unit 5 and the wireless communication medium 1. There is also an advantage that it is not necessary to change the bit stream configuration of the wireless communication medium 1. For this reason, the cost reduction effect is also great.

  Next, a method for starting processing in response to a change in the weight measuring unit 4 and a method for re-execution when there is a difference between the calculated values will be described with reference to FIGS.

  In FIG. 7, the weight change detection means 17 is connected to the weight measurement unit 4 and the read / write unit 5. The weight change detection means 17 detects a change in weight when the article 2 is mounted on the weight measuring unit 4 or a change in weight due to removal of the mounted article 2. Change detection is detected when the weight measured in a certain cycle is monitored and the weight is different before and after the monitoring cycle. When a change in weight is detected, the result is notified to the read / write unit 5.

  The read / write unit 5 starts communication with the wireless communication medium 1 via the antenna 3 only after receiving the notification. For example, when a weight change notification is received, a signal current is supplied from the read / write unit 5 to the antenna 3 or the power supply of the read / write unit 5 is normally turned off. Communication with the communication medium 1 is started.

  As described above, communication with the wireless communication medium 1 is performed only when a weight change occurs in the weight change detection unit 17, thereby reducing standby power and reducing electromagnetic wave leakage around the apparatus. It is.

  As described above, since the change in weight is detected whether it is an increase or a decrease, when the article 2 is newly mounted on or added to the weight measuring unit 4, or In any case, such as when it is removed, the operation is started only after these changes are detected, which is very effective in automatic checkout of goods or automatic inspection.

  FIG. 8 shows a case where the re-execution instruction unit 18 is attached.

  The re-execution command unit 18 is connected to the weight comparison unit 13 and the read / write unit 5. The re-execution command unit 18 is notified of the result when the physical measurement weight in the weight measurement unit 4 and the calculated weight based on the ID code 6 do not match in the weight comparison unit 13. When there is this notification, the re-execution command unit 18 instructs the read / write unit 5 to read and execute the ID code 6 from the wireless communication medium 1 again. Receiving this command, the read / write unit 5 communicates with the wireless communication medium 1 again, and is repeated until the comparison result in the next weight comparison unit 13 matches. This ensures that the process is continued until correct reading is possible.

Thus, the presence of the re-execution command unit 18 allows a final result to be obtained without bothering the user, so that the process is efficiently executed. Moreover, it is preferable to use the weight change detecting means 17 described in FIG. 7 together with this, because it is possible to achieve a balance between power reduction and reliable execution completion.

  Next, the case where it applies to an automatic liquidation is demonstrated using FIGS. 9-13.

  The price clearing unit 19 is connected to the weight comparison unit 13, and the price display unit 20 is connected to the price clearing unit 19.

  In the price clearing unit 19, based on the ID code 6 read from the wireless communication medium 1 by the read / write unit 5, the total amount of each article 2 read out from the information table 11 in which price information is stored in addition to the weight information. Is calculated. The calculated price is displayed on the price display unit 20.

  The price clearing unit 19 may calculate including tax or separately. Further, the price clearing unit 19 may calculate all of the unit price, the quantity, and the total amount for each type of the article 2 and display them on the price display unit 20 based on the result. Further, the price display unit 20 is composed of a liquid crystal, an LED, or the like.

  Further, FIG. 9 shows the case where the price clearing unit 19 or the like is stored in or integrated with the host 9, but only the price clearing unit 19 or the like is different from the register device 21 or the like as shown in FIG. 10. It may be incorporated in the apparatus.

  In FIG. 10, the cash register 21 is configured separately from the host 9, and the result of the weight comparison unit 13 stored in the host 9 is notified to the price clearing unit 19 inside the cash register 21, and the price is displayed. Is called.

  Price settlement is executed in the weight comparison unit 13 only when the physical measurement result in the weight measurement unit 4 matches the calculation result. If they do not match, the settlement result is different from the original, so the settlement is not executed or an error is displayed.

  Next, FIG. 11 shows a case where a re-execution command unit 18 is added. If the weight comparison unit 13 does not match as described with reference to FIG. On the other hand, if the communication with the wireless communication medium 1 is instructed again, and the re-reading results in a match in the weight comparison unit 13, price calculation is performed in the price clearing unit 19 from that point.

  As described above, the addition of the re-execution instruction unit 18 has an advantage that the price settlement is surely completed.

  If the result of the re-execution in the weight comparison unit 13 does not give a coincidence result, it is considered that there is a device failure or other failure, so that the re-execution command in the re-execution command unit 18 is issued. It is also preferable to stop and notify and display a warning or the like by the notification means 14 or the like. By such processing, it is possible to prevent the execution processing from being delayed unnecessarily by repeating the routine.

  Next, FIG. 12 shows a case where a shopping basket is placed on the weight measuring unit 4 and automatic price settlement is performed.

  By placing the shopping basket 22 within the communication range of the antenna 3 and allowing the antenna 3 to apply a magnetic field inside the shopping basket 22, for example, the articles 2 put in the shopping basket 22 at the time of shopping are automatically collected together. There is merit that can be liquidated.

  In addition, an extra antenna 3 is placed on the weight measuring unit 4 by using a shopping basket 22 having a box-shaped bag with an antenna already installed, such as the structure 15 shown in FIG. Automatic settlement and the like can be executed more easily. It is the form shown by FIG. Further automation is promoted by using, for example, a shopping basket or a product box as the structure 15 in which the antenna 3 is incorporated in advance and communication with the wireless communication medium 1 existing inside is possible. .

  These are preferably applied to, for example, a centralized cash register in a supermarket, or to automatic inspection at a warehouse or a distribution base.

  The above automatic settlement will be described with reference to the processing flowchart in FIG.

  First, after starting (ST11), an article is placed on the weight measuring unit 4 (ST12). At this time, the case may be used as usual, the shopping basket 22 may be used, or the box-shaped structure 15 may be used. Next, the weight measurement result in the weight measuring unit 4 is notified to the host (ST13). Next, the ID code 6 read by the read / write unit 5 is notified to the host (ST14), and weight calculation and price calculation are performed according to the information from the information table 11 (ST15). Next, the measurement result and the calculation result are compared in the weight comparison unit 13 (ST16). If they do not match, the notification means 14 notifies that and the re-execution is instructed (ST17). After that is output (ST18), the total amount is notified and settlement is processed (ST19). As a result, a series of processing ends (ST20).

  As described above, the weight physically measured by the weight measuring unit 4 is compared with the calculated weight based on the ID code 6 read from the wireless communication medium 1 by the read / write unit 5. Therefore, without adding an extra circuit or extra procedure to the wireless communication medium 1 or the read / write unit 5, it is possible to immediately detect a reading error or an unread and to provide a highly reliable automatic liquidation and automatic inspection system. It becomes possible to construct. As a result, a system capable of automatic processing at high speed processing is constructed.

(Embodiment 2)
In the second embodiment, a system in an airport security gate, automatic inspection in a warehouse, or the like will be described.

  15 and 16 are configuration diagrams of the wireless communication medium processing system according to the second embodiment of the present invention, and FIG. 17 is a perspective view of the gate antenna according to the second embodiment of the present invention.

  Reference numeral 23 denotes a package and the wireless communication medium 1 is attached. Reference numeral 24 denotes a gate antenna. Reference numeral 25 denotes a transport path. Reference numeral 26 denotes a feeding antenna. Reference numeral 27 denotes a non-feeding antenna. Reference numeral 28 denotes a resonance circuit. Reference numeral 30 denotes a terminating resistor. Components having the same reference numerals as those in FIG. 1 and the like are portions that perform the same operation.

  The load 23 attached with the wireless communication medium 1 is automatically placed on a transport path 25 such as a belt conveyor. The weight measuring unit 4 and the gate antenna 24 are installed at an arbitrary place on the transport path 25. When the load 23 reaches this place, the weight is measured by the weight measuring unit 4, and the communication of the gate antenna 24 is performed. Communication with the wireless communication medium 1 is executed by entering the range. For example, it is also preferable that the weight measuring unit 4 automatically stops the transport path 25 and performs processing. In this case, for example, it is also preferable to set the condition for stopping the transport path 25 to be a change in mutual inductance due to application of a magnetic field for communication with the wireless communication medium 1 by the gate antenna 24, for example.

  The weight measuring unit 4 physically measures the weight of the load 23, and the gate antenna 24 applies a magnetic field to the wireless communication medium 1. An induced electromotive force is generated in the wireless communication medium 1 subjected to the magnetic field, and the ID code 6 stored in the internal memory changes the mutual inductance, and this change is transmitted to the read / write unit 5 as a signal. . The read / write unit 5 demodulates this signal, reads the ID code 6, and notifies the host 9. The host 9 extracts the weight information according to the ID code 6 from the information table 11 and calculates the weight of the load 23.

  In addition, a measurement result output unit 7 that outputs a measurement result measured by the weight measurement unit 4 to the host 9 and an extraction result that notifies the host 9 of a calculation result calculated from the weight information extracted from the information table 11 An output unit 12b is provided, and the output contents thereof are displayed on the display unit of the host 9 or the like, and are easily viewed and confirmed by the user. For this reason, if it is a simple system, the comparison of a weight etc. can be performed by human work, without requiring the comparison means etc. which are mentioned later. Of course, it is also possible to approximate the difference in weight, and it is possible to confirm that a reading error or the like has occurred when there is a mismatch. Of course, by making all automatic by the weight comparison unit 13 and the notification means 14 described below, it is possible to save labor and to construct a lower-cost system.

  In the important comparison unit, when the physically measured weight and the calculated weight are compared and coincident with each other, it is determined that there is no reading error or unreading of the wireless communication medium 1, and that is notified by the notification unit 14. The user is notified, and if there is a mismatch, it is notified that there is a reading mistake or the like.

  This may be a single package or a plurality of packages 23, and since the exchange with the wireless communication medium 1 is performed at a very high speed, the processing is actually performed one after another without stopping the transport path 25. It is executed continuously. As a result, it is widely applied to, for example, airport security gates.

  At this time, if there is a discrepancy in weight, the load 23 may be removed, returned to the beginning of the transport path 25, and reinspected. Alternatively, the transport path 25 may be reversely transported once so that the same baggage 23 passes through the gate antenna 24 again, or the transport path 25 is stopped and communication with the wireless communication medium 1 is performed again. It may be re-executed. Alternatively, if there is a suspicious point in the baggage 23, a measure such as a detailed content survey may be separately performed. By doing in this way, the automatic inspection etc. which are used suitably for inspection, security, etc., and have greatly reduced human labor can be performed with high accuracy.

  It should be noted that a range that is regarded as coincidence of coincidence determination may be determined according to the weight of the luggage 23. Those that are very heavy may have very large error ranges that are considered coincident.

  FIG. 16 shows a gate antenna composed of two loop-shaped antennas opposed to the gate antenna 24. In this case, there is a merit that communication with the wireless communication medium 1 is more reliable. Since the gate antenna 24 is composed of two loop-shaped antennas facing each other, in this facing region, the magnetic field surely reaches the wireless communication medium 1 and the luggage 23 passes through the facing region of the gate antenna 24 by the transport path 25. There is an advantage that the communication with the wireless communication medium 1 attached to is reliably performed and the reading accuracy is improved.

  At this time, it is also preferable that one of the gate antennas 24 is a feeding antenna 26 to which a signal current is fed and the other is a non-feeding antenna 27 to which a signal current is not fed.

  FIG. 17 shows a gate antenna. The feeding antenna 26 and the non-feeding antenna 27 face each other, and an induced electromotive force is generated in the non-feeding antenna 27 by a magnetic field generated from the feeding antenna 26, and a current is also generated in the non-feeding antenna 27. As a result, a magnetic field due to the induced current is also generated from the non-feed antenna 27 and operates as an antenna that applies a magnetic field to the wireless communication medium 1 existing around the non-feed antenna 27. Further, since the feeding antenna 26 operates by generating an induced current in the non-feeding antenna 27, there is no phase difference in the currents flowing through the respective antennas, and no mutual adverse effect occurs in communication with the wireless communication medium 1. There is. In addition, since one of them is naturally non-powered, the communication range can be expanded while reducing power consumption. For this reason, the width of the conveyance path 25 is very wide by the gate antenna 24 in which two loop-shaped antennas are opposed to each other, and the gate antenna 24 configured by a single antenna can communicate with the wireless communication medium 1. It is very effective when it is insufficient.

  In addition, by connecting the resonance circuit 28, the matching circuit 29, and the termination resistor 30 to the non-feed antenna 27, it is possible to realize resonance at a desired frequency and to ensure impedance matching, and to communicate with the wireless communication medium 1. Accuracy can be ensured.

  As described above, the gate antenna 24 is arranged on the transport path 25 such as a belt conveyor, the weight measuring unit 4 is installed at the position, and the apparatus connected to the host 9 is configured to perform physical measurement. By comparing the calculated weight with the calculated weight extracted based on the ID code 6 obtained from the wireless communication medium 1, it is possible to immediately detect whether the wireless communication medium 1 has not been read or read mistakes. Furthermore, when a reading error occurs, a reliable inspection and security check can be completed by automatically performing a re-inspection or switching the processing flow to a separate detailed investigation.

  Further, unlike the conventional method, since only the ID code 6 is stored in the wireless communication medium 1, no extra storage area is required, and the weight, product number, price, etc. that can be changed frequently other than the ID code 6 This information update is simple and efficient by only updating the information table included in the host. Furthermore, there is no need to repeatedly communicate with the wireless communication medium 1, and it is not necessary to set extra circuits and program processing in the read / write unit and the wireless communication medium. Another advantage is that there is no need to change the bit stream configuration of the wireless communication medium. For this reason, the cost reduction effect is also great.

  These can be effectively applied not only to airport gates, but also to warehouses such as logistics warehouses and supermarkets, rolling stocks, automatic inspections such as employee cafeterias, and automatic liquidation.

  The present invention relates to a wireless communication medium attached to an article, an antenna that communicates with the wireless communication medium, a weight measuring unit that measures the weight of the article, and an ID of the wireless communication medium from the wireless communication medium via the antenna. A read / write unit that reads the code, an information extraction unit that extracts the weight information of the article with the ID code read from the ID code read by the read / write unit, and a measurement result output unit that outputs the measurement result of the weight measurement unit Because the configuration having the extraction result output unit that outputs the calculation result of the weight extracted by the information extraction unit, it is possible to immediately detect reading errors and unreading of the wireless communication medium attached to the article to be read It can also be applied to applications that require automatic inspection of many items at once.
