  FIG. 1 shows that the end user is connected to the external Internet network 5 through a communication carrier in order to enjoy the Internet service and the like. That is, the end user area 7 is connected to the communication control server 1 through the communication line 6 of the communication carrier, and is connected to the external Internet network 5 through the gateway 4.

  More specifically, the end user communicates with the communication control server via the communication method conversion unit 10 and the connection unit 8 through the communication line 11 in which the electronic device 12 and the wireless communication electronic device 15 in the end user area 7 have different media. 1 side is connected. Note that the wireless electronic device 15 whose communication method is a wireless medium is connected to the communication line 11 via the wireless access point 13.

In such an environment, the location search of the device is performed as follows.
Upon receiving a request from the manufacturer or seller, the telecommunications carrier sends device identification information, which is individual identification information for device identification, to the communication control server 1 owned or borrowed by the telecommunications carrier through the input / output device 2. The storage unit 1 a in the communication control server 1 stores the part in the data management unit 3 of the communication control server 1.

  Then, the location search command means 1c of the communication control server 1 issues a location search command for the device based on the input device identification information by an operation through the input / output device 2 of the communication carrier. The device location search command issued by the location search command means 1 c is sent to the connection unit 8 in the end user area 7 and the connection unit 9 of other end users through the communication line 6.

  The case where the command is acquired at the connection unit 8 in the end user area 7 will be described. The location search command of the device received by the connection unit 8 is transmitted from the communication system conversion unit 10 to the communication line 6 as a signal of the command. Are converted to correspond to the communication line 11 having different values, and reach the electronic device 12 through the communication line 11. Further, this command reaches the wireless access point 13 through the communication line 11 and reaches the wireless electronic device 15 through the wireless communication path 14.

  In the electronic device 12, the transmitted location search command is received by the transmission / reception unit 12a, and the control unit 12c matches the device identification information based on the command with its own device identification information stored in advance through the storage unit 12b. Determine whether. If the control unit 12c determines that they match, the match information is transmitted to the communication control server 1 side as response information via the transmission / reception means 12a.

  That is, the response information from each electronic device 12 is sent to the communication control server 1 through the communication line 11 via the communication line 11 via the communication method conversion unit 10 and the connection unit 8. At this time, the connection unit 8 in the end user area 7 performs processing for adding user information for identifying the end user in the end user area 7 to the response information. This user information includes end user location information.

  Then, the communication control server 1 acquires the response information to which the user information is added by the communication unit 1b, so that the response information is displayed on the input / output device 2, and the information on whether the information matches or does not match is notified to the communication carrier. Is done. Along with this notification, the storage means 1 a in the communication control server 1 creates and stores a corresponding list of end users based on the device identification information in the data management unit 3.

  In the above-described embodiment, whether the device matches or does not match by the control unit 12c is transmitted to the communication control server 1 as response information even in both cases. The present invention also includes embodiments that are not transmitted in some cases. In this case, the input / output device 2 of the communication control server 1 displays device matching information and user information including user information.

  According to the embodiment as described above, based on the input device specifying information, it is possible to appropriately notify the location information of each device possessed by the end user to the communication carrier.

[2. Second Embodiment]
In the first embodiment of the present invention, responses from end users are concentrated at the same time, and there is a possibility that the communication line is congested. Therefore, the second embodiment proposed to solve such a problem. A form is demonstrated below with reference to FIG.

  As shown in FIG. 4, the communication control server 1 includes a delay time setting means 1d for setting a delay time of a response to the communication control server 1 with respect to the device for each end user in order to prevent concentration of responses from the end user. I have. The delay time set by the delay time setting means 1d is that communication is generally placed on a loading platform (packet or payload) on the time axis that is a communication frame, so the timing for sending the communication frame is adjusted time. Is shown.

  Here, the delay time setting unit 1d in the present embodiment adjusts the timing of sending the communication frame using a unique address that identifies the end user or a random number generated by the random number generation unit 1e.

  When using a unique address for identifying a user, the delay time setting unit 1d sets a delay time based on the address, which is user information stored in the data management unit 3 through the storage unit 1a. The address is determined in advance based on a contract between each end user and the communication carrier.

  When using random numbers, the communication control server 1 is provided with random number generating means 1e using a PN code (pseudo noise code), and the delay time setting means 1d uses the random numbers generated by the random number generating means 1e. Set the delay time. The random number generating means 1e is composed of N stages of shift registers, and is composed of M feedback circuits and L adders / subtracters. It is possible to select the number of shift registers of the random number generating means 1e and the configuration of the feedback circuit according to the number of random numbers required and the type of random number.

  According to the embodiment as described above, by setting the delay time for each end user, it is possible to avoid simultaneous concentration of responses from the end user and to prevent congestion occurring in the communication line.

  For example, in the case of mass-produced products, there are many 100,000 units per lot, and if 100,000 communications occur at a time in response to a search, the amount of information reaches about 1 Gbit even if the amount of information is 1 kbyte. End up. Therefore, if each response is processed at a transmission rate of 1 Mbps, 1000 lines are required, and congestion occurs for 1 second. Therefore, as in the present embodiment, a delay time is set for each end user, and for example, by distributing such information amount over 10 seconds, processing with 100 lines becomes possible, and the surplus lines are congested. To prevent.

  In addition, the delay time setting means 1d can use not only a unique address that is user information but also a random number generated by the random number generation means. It can also be avoided. Furthermore, by using the random number information attached to each end user for the waiting time setting of the CSMA / CA (CarrierSense Multiple Access with Collision Avoidance) method used for the wireless LAN, it is possible to further avoid simultaneous concentration of information and appropriately prevent congestion. It becomes possible.

[3. Third Embodiment]

For example, manufacturers and sellers need lot management that is promptly adapted to the timing of product shipment or sales. As a result, it is necessary to rewrite a part of product identification information even in a packaged state. However, unpacking to rewrite the identification information and connecting the writing tool to the electronic circuit is a heavy burden and also costs for re-purchasing packing materials and the like.
The device search system according to the third embodiment is proposed in order to solve such a problem.

[3.1. Constitution]
First, a configuration example of a device search system based on individual identification information of a device having a communication unit according to the third embodiment will be shown.

  As shown in FIG. 5, reference numeral 21 denotes an electronic device 12 or a wireless electronic device 15 having communication means held by an end user provided in the end user area 7, which is a search target of the present invention shown in FIG. 1. . Reference numeral 22 denotes a communication line from the device 21 connected to the communication line 11.

  23 is a means similar to the transmission / reception means 12a in the electronic device 12 shown in FIG. 3 for performing communication with the communication line 22, and 24 is the device 21 corresponding to the control unit 12c shown in FIG. It is a control unit. Reference numeral 25 denotes a wireless tag element in which device identification information of the device 21 possessed by the end user is written. Reference numeral 26 denotes a communication path for the control unit 24 to communicate and control the wireless tag element 25. .

  Here, the RFID tag element 25 to be used may be either a passive type or an active type, but the passive type is adopted in the device 21 in which the power supply may be interrupted for a long time. In the case of the passive type, the communication path 26 between the passive type wireless tag element 25 and the control unit 24 may be any of wireless, electrostatic coupling type, electromagnetic induction type non-wired system. .

  Reference numeral 27 denotes a control device having wireless communication means for writing information to the wireless tag element 25 and reading information from the wireless tag element 25. 28 is a communication path between the RFID tag element 25 and the control device 27 provided in the device 21, and 29 is device identification information for writing to the RFID tag element 25 via the control device 27. It is a storage device.

[3.2. Effect]
Next, the operation of the device search system of the third embodiment having the above configuration will be described in detail below.

  When the device 21 is shipped or sold, the control device 27 reads device type information for specifying the device 21 and device specifying information such as a manufacturing number from the storage device 29 according to instructions from the manufacturer or seller. This information is written into the wireless tag element 25 via the communication path 28 by means such as radio waves. Whether the data has been correctly written in the wireless tag element 25 is determined by the control device 27 by reading the information written in the wireless tag element 25 and comparing it with the information stored in the storage device 29.

  Here, the device search operation of the device search system shown in FIGS. 1 and 5 under the situation where the device identification information is written in the wireless tag element 25 as described above will be described below.

  Upon receiving a request from the manufacturer or seller, the telecommunications carrier inputs device identification information for device identification through the input / output device 2 to the communication control server 1 owned or borrowed by the telecommunications carrier, and the communication A part of the storage unit 1 a in the control server 1 stores the data in the data management unit 3 of the communication control server 1. Then, by the operation through the input / output device 2 of the communication carrier, the location search command means 1c of the communication control server 1 issues a location search command for the device based on the device identification information input. The device location search command issued by the location search command means 1 c is sent to the connection unit 8 in the end user area 7 and the connection unit 9 of other end users through the communication line 6.

  The case where the command is acquired in the connection unit 8 in the end user area 7 will be described. The device location search command received by the connection unit 8 is transmitted from the communication system conversion unit 10 so that the signal of the command is a medium different from the communication line 6. Are converted to correspond to the communication lines 11 having different values, and reach the device 21 (corresponding to the electronic device 12 and the wireless electronic device 15 in FIG. 1) through the communication line 11.

  In the device 21 of FIG. 5, the location search command sent from the communication control server 1 through the communication line 22 is received by the transmission / reception means 23, and the control unit 24 sends the wireless tag element 25 to the wireless tag element 25 via the communication path 26. Queries the device identification information written in the tag element 25. In response to this inquiry, the wireless tag element 25 transmits the written device identification information to the control unit 24 via the communication path 26.

  When receiving the device identification information from the wireless tag element 25, the control unit 24 determines whether the device identification information matches the device identification information based on the location search command. If the control unit 24 determines that they match, the match information is sent to the communication line 22 via the transmission / reception means 23 as response information, and the mismatch information is sent as response information to the communication control server 1 side. Send. Since the subsequent processing is the same as that of the first embodiment, description thereof is omitted.

  Note that when the information is written in the wireless tag element 25, the control unit 24 can also read the information immediately and store it in a storage unit possessed by the control unit 24. However, when power supply is interrupted for a long period of time, power supply to the storage unit of the control unit 24 becomes uncertain, so that it is more stable to use the information storage function of the passive RFID tag element 25. Can be secured. For this reason, manufacturers and sellers need to select an information storage method according to the usage situation.

  According to the embodiment as described above, a manufacturer or a seller writes device identification information such as device type information and a serial number in the wireless tag element 25 without energizing the device 21 at the time of shipment or sale. Can do. As a result, even when the power supply is disconnected or shipped in the manufacturing process, the device identification information can be written to the device 21. It is also possible to read and check with the control device 27.

  Currently, there are a plurality of (three) types of communication standards for power line communication internationally. Specifically, the internationally popular power line communication method is the HD-PLC (High Definition-Power Line Communication) standard or CEPCA (CE-Power line Communication Alliance), which uses Wavelet OFDM / PAM as a modulation method mainly in Japan. Standards, HomePlugPowerlineAlliance “HomePlugAV” standard that uses Windowed OFDM / QAM as a modulation system mainly in the United States, and UPA (Universal Powerline Association) standard that uses Windowed OFDM / QAM as a modulation system mainly in Spain. Raise.

  Here, when devices in one home or office use different standards, there arises a problem that signals of different modulation schemes simultaneously travel on the power line (electric light line) and cause interference. Note that the MAC system uses TDMA / CSMA / CA, TDMA / CSMA / CA, and token bus systems, respectively. Even if the modulation system is similar, there is a problem that interoperability is difficult because the MAC system is different. ing.

Currently, discussions are being held in search of a unified standard, but the situation is extremely difficult, and in order to make information transmission through power line communication a component, it is indispensable to realize a method that handles multiple methods It is in.
