1.7 Summary
As described above, the portable reader / writer 20 transmits an access request command using three types of carrier waves in the same time zone, and the wireless IC tag 10 transmits its frequency band type and communication protocol type. Further, the portable reader / writer 20 writes information to the wireless IC tag 10 or reads information from the wireless IC tag 10 using the received frequency band type and communication protocol type.
[0085]
Thus, even when the frequency band that can be received by the wireless IC tag 10 is different, the portable reader / writer 20 can communicate with the wireless IC tag 10.
Standards are inconsistent due to application examples such as wireless IC tags attached to or embedded in "things" such as parts and members, or wireless IC cards used for entry / exit of people or tickets Even when a mixture of communication frequency, modulation / demodulation method, protocol, data format, security method, encryption method, etc. is used, as described above, between the reader / writer and the wireless IC tag You can communicate with.
[0086]
In the above embodiment, the tag type may further include a modulation / demodulation method, a data format, a security method, or an encryption method.
1.8 Modification of portable reader / writer 20 (1)
The portable reader / writer 20 may be configured as follows.
As shown in the flowchart of FIG. 24, the portable reader / writer 20 generates an access request command in the 125 KHz band (Step S201), and outputs an access request command in the 125 KHz band (Step S202).
[0087]
The portable reader / writer 20 waits for reception of the tag type in the 125 KHz band (step S203), and if there is reception of the tag type (step S204), performs access processing with the wireless IC tag 10 in the 125KHz band (step S204). S205).
If no tag type is received within the predetermined time (step S204), the portable reader / writer 20 then generates an access request command in the 13 MHz band (step S206), and outputs an access request command in the 13 MHz band. (Step S207).
[0088]
The portable reader / writer 20 waits for reception of the tag type in the 13 MHz band (step S208). If there is reception of the tag type (step S209), the portable reader / writer 20 performs access processing with the wireless IC tag 10 in the 13 MHz band (step S209). S210).
If no tag type is received within the predetermined time (step S209), the portable reader / writer 20 then generates an access request command in the 2.4 GHz band (step S211), and accesses in the 2.4 GHz band. A request command is output (step S212). The wireless IC tag 10 reads the tag type (step S213) and outputs it (step S214).
[0089]
The portable reader / writer 20 waits for reception of the tag type in the 2.4 GHz band (step S215). If there is reception of the tag type (step S216), the portable reader / writer 20 performs access processing with the wireless IC tag 10 in the 2.4 GHz band. Is performed (step S217).
As a result, the portable reader / writer 20 can communicate with the wireless IC tag 10 even if the wireless IC tag 10 has various specifications with different frequency bands that can be received.
1.9 Modification of portable reader / writer 20 (2)
The portable reader / writer 20 may be configured as follows.
[0090]
The portable reader / writer 20 has a frequency band type history table 251 as shown in FIG. 25 as an example.
The frequency band type history table 251 stores ten frequency band types of wireless IC tags accessed in the last past.
26, the portable reader / writer 20 reads all frequency band types from the frequency band type history table 251 and generates the frequency of occurrence for each type of frequency band type included in the frequency band type history table 251. (Step S221), the most frequent frequency band as the first output frequency band (step S222), the next most frequent frequency band as the second output frequency band (step S223), and the least frequent frequency The band is set as the third output frequency band (step S224). In this way, the output order according to the frequency band is determined in the order of the first output frequency band, the second output frequency band, and the third output frequency band.
[0091]
Next, in the above modification (1), an access request instruction is output in this order. Specifically, the first output frequency band is used in steps S201 to S202 of the flowchart shown in FIG. 24, the second output frequency band is used in steps S206 to S207, and the third output frequency band is used in steps S211 to S213. Is used.
[0092]
When the communication with the wireless IC tag is completed in this way, the portable reader / writer 20 newly writes the frequency band type used for communication with the wireless IC tag in the frequency band type history table 251, and the frequency band written first is written. The type is deleted from the frequency band type history table 251.
In this way, the priority of the frequency band type to be used next is determined using the frequency of the frequency band type used for communication in the past, and the access request command is transmitted in the order of the frequency band according to the determined priority. To do. As a result, even if the wireless IC tag 10 has various specifications with different frequency bands that can be received, the portable reader / writer 20 can communicate with the wireless IC tag 10 and can communicate with the wireless IC tag 10. The frequency band that can be used in is statistically quickly determined.
1.10 Modification of access system
The wireless IC tag 10 and the portable reader / writer 20 may encrypt data to be communicated in order to ensure the security of communication between them. The wireless IC tag 10 and the portable reader / writer 20 store programs for encryption and corresponding decryption. One device encrypts and transmits data, and the other device encrypts data. The received data is received and decoded. An example of a cryptographic algorithm is a chaos cipher and a logistic map
X (t + 1) = 4X (t) {1-X (t)}
Is generated sequentially to generate a chaos block cipher.
1.11 Modification of access system
The access system may be configured as follows.
[0093]
The memory unit 210 includes a first area composed of a semiconductor memory capable of reading information a plurality of times and overwriting information a plurality of times, and a semiconductor memory capable of reading information a plurality of times and writing information only once 2nd area | region comprised from these. In FIG. 12, the non-protection part 231 and the protection part 232 are the first area, and the one-time 233 is the second area.
[0094]
The wireless IC tag determines whether to access the first area or the second area based on the received access command. Here, the determination is performed using a physical address included in the access command. That is, the determination is made based on whether the physical address indicates the first area or the second area. Next, the first area or the second area is accessed based on the determination result.
[0095]
An example of information stored in the second area is a warranty period and a warranty number of an article. An example of the access device is a sales management device that manages sales of an article to which the information storage medium is attached. The access device accepts a deposit operation from an operator, and when the deposit operation is accepted, generates an access request for requesting an access instruction indicating writing of warranty information indicating a warranty condition of the article to the second area To do. The information storage medium determines that the access is to the second area, and writes the guarantee information to the second area based on the determination result.
[0096]
As an application example at the point of sale, use the store by storing the warranty information such as the date of sale, the name of the store, the warranty period and the warranty conditions of the product in the wireless IC tag via the reader / writer. A wide range of services and maintenance is possible, such as handling problems at times, upgrades, and collection of quality problems. This eliminates the need for conventional warranty storage and misleading inquiry processing, which can be used to improve customer satisfaction.
[0097]
Another example of the information stored in the second area is manifest information at the time of collection of the article. An example of the access device is a collection management device that manages collection of an article to which the information storage medium is attached. The access device receives an operation from an operator, and when the operation is received, generates an access request for requesting an access instruction indicating writing of the manifest information of the article into the second area. The information storage medium determines that the access is to the second area, and writes the manifest information to the second area based on the determination result.
[0098]
The manifest method, which is currently being enacted, uses a slip of several sheets of paper. Household appliances (TV receivers, air conditioners, refrigerators, washing machines) are targeted, and the discharger brings them to the store, pays the processing fee, and receives the manifest slip as the processing registration slip. The company involved in the scrap of processing is a mechanism for storing this for 5 years. It is clarified in this slip that the processing is appropriate for the inquiry about the processing from the discharger. However, this mechanism is expected to cost a lot of paper, storage costs, and search checks. In order to solve this, in the process of collection / recycling, information recorded in a wireless IC tag embedded in the device is read by a reader / writer, stored in a host computer, and communication means such as the Internet as necessary. Emissions can be checked via In this way, a quick and low-cost collection system can be constructed.
[0099]
Furthermore, using the types and amounts of environmentally hazardous substances stored in advance in the wireless IC tag, the contents can be read and used as a collection record during collection and recycling. In calculating the recycling rate, the data (type and weight) of each member recorded in the tag at the time of manufacture can be read by a reader / writer, and can be written and used in the host computer as a record of separation and recycling amount. .
[0100]
Also, with regard to more complicated procedures and handling methods such as product disassembly information and environmentally hazardous substance extraction methods, it is impossible to store everything in this wireless IC tag because of memory capacity, price, etc. Only the identification code for search in this method is stored, and details of these methods are stored in the host computer. The identification code is read from the wireless IC tag by the reader / writer, and the corresponding method is read from the host computer using the identification code. The read method may be displayed and printed on a reader / writer or a personal computer.
[0101]
Another example of the information stored in the second area is environmental load substance information (for example, the type and amount of alternative chlorofluorocarbon) related to the environmental load substance constituting the article. An example of the access device is a manufacturing management device that manages manufacturing of an article to which the information storage medium is attached. The access device accepts an operation from an operator, and when the operation is accepted, the access device requests an access instruction indicating writing of the environmental load substance information indicating the environmental load substance included in the article into the second area. Generate a request. The storage information medium determines that the access is to the second area, and writes the environmental load substance information to the second area based on the determination result. Other examples other than the environmental load substance information include assembly condition, processing condition, inspection condition, production condition information at the time of production such as measurement values, lot number, production factory name, and production date. The above information can be read and used for service, collection and recycling, etc. at the time of recycling / recovery and service such as product repair. At the time of product repair and recovery, the manufacturing conditions may be read out, and the repaired, dismantled, and reused products may be performed using the read out manufacturing conditions.
