Abstract

The wireless IC tag chip 12 storing the identification number (1) 18 is attached to the cable terminal, and the IC chip 21 storing the identification number (2) 26 is also attached to the terminal block terminal. When the cable is coupled to the terminal block, the wireless IC tag chip 12 is coupled simultaneously with the IC chip 21. Further, when the cable is separated from the terminal block, the wireless IC tag chip 12 is simultaneously separated from the IC chip 21. The selected wireless IC tag chip 12 transmits the recognition number (1) 18 and the recognition number (2) 26 to the reader by electromagnetic waves from the reader. By transmitting a different identification number depending on whether the wireless IC tag chip 12 and the IC chip 21 are coupled or separated, the reader can automatically recognize the cable status. Accordingly, normality when the cable is coupled to and separated from the terminal block can be realized economically and efficiently, and damage due to erroneous operation of coupling and separation of the cable can be reduced.

(Embodiment 1)
FIG. 1 shows one embodiment of the present invention. This figure shows the structure of an IC tag having terminals for connecting to other IC chips. The antenna 11 is connected to the IC tag chip 12, and the identification number (1) 18 is stored in the IC tag chip 12. This identification number (1) is an identification number indicating the terminal of the cable. A power terminal 13, a clock terminal 14, a data terminal 15, and a ground terminal 16 are connected to the IC tag chip 12 through a connection line 17.

  The recognition number (1) 18 can be read by a reader (reading device) using electromagnetic waves. The signal levels of the power supply terminal 13, the clock terminal 14, the data terminal 15, and the ground terminal 16 can be manipulated according to the presence or absence of electromagnetic waves applied to the IC tag chip 12 from the reader or a modulation signal. However, when each terminal is not connected, the operation of reading the identification number (1) is not affected. In the embodiment of the present invention, these signal terminals will be described as examples.

  Regarding the effects and technical embodiments obtained by connecting the IC tag chip 12 and other IC chips, there are other methods including the number of signals, the signal level, and the coupling method as well as the realization of the present embodiment alone. In the present invention, a technological advance is claimed not only in this embodiment but also in a form of connection with another IC chip or an IC tag chip by providing a connection terminal on the IC tag chip as required.

  FIG. 2 shows one embodiment of the present invention. This figure shows the structure of an IC chip having terminals for connecting to other IC tags. The IC chip 21 is connected to a power terminal 22, a clock terminal 23, a data terminal 24, and a ground terminal 25 on the IC chip side via a connection line 27. Further, the identification number (2) 26 is stored in the IC chip 21.

  FIG. 3 shows one embodiment of the present invention. This figure shows that an IC tag and an IC chip are connected. The power supply terminal 13, the clock terminal 14, the data terminal 15, and the ground terminal 16 on the IC tag chip 12 side, and the power supply terminal 22, the clock terminal 23, the data terminal 24, and the ground terminal 25 on the IC chip 21 side are connected to each other. Yes. The antenna 11 is irradiated with electromagnetic waves from a reader, and the identification number (1) 18 in the IC tag chip 12 and the identification number (2) 26 in the IC chip 21 are sequentially read by a modulation signal from the reader. The voltage at the power terminals 13 and 22 rises when electromagnetic waves are applied to the antenna 11 of the IC tag chip 12. At the clock terminals 14 and 23, the clock signal from the reader is demodulated to generate a signal level clock signal. When this clock signal is sent from the IC tag chip 12 to the IC chip 21, the IC chip 21 serially outputs the internal identification number (2) to the data terminal 24, and sends the data signal from the IC chip 21 to the IC tag chip 12. send. The IC tag chip 12 transmits this data signal to the reader via the antenna.

  FIG. 4 shows one embodiment of the present invention. This figure is an internal drawing of the IC tag chip 12 having a structure having an antenna and a connection terminal. The antenna 11 connected to the IC tag chip 12 is connected to a rectifier circuit 41. The rectifier circuit 41 has a role of converting AC energy from the reader into a DC power supply voltage. A signal from the rectifier circuit 41 is connected to the clock extraction circuit 42. The clock extraction circuit 42 demodulates the clock signal from the output signal of the rectifier circuit 41. The clock signal from the clock extraction circuit 42 is input to the counter circuit 44. The counter circuit 44 drives the memory circuit 17a in which the identification number (1) 18 is stored, and the memory circuit 17a has the identification number (1). Data is sequentially sent to the AND circuit 46b. At this time, the counter circuit 44 is counted up by the clock signal, and the count value of the counter circuit 44 corresponds to the memory address of the memory circuit 17a. The data of the identification number (1) from the memory circuit 17a is output to the transmission circuit 43 via the AND circuit 46b and the OR circuit 47.

  The counter circuit 44 has a carry detection circuit 45, which detects that the counter circuit 44 has finished a predetermined count. When this end is detected, subsequent transmission of the identification number (1) is prohibited by the inverter 48, the AND circuit 46b, and the OR circuit 47. Note that the transmission signal of the data of the identification number (1) is transmitted to the reader via the transmission circuit 43 and the antenna 11.

  On the other hand, when the carry detection circuit 45 detects that the counter circuit 44 has finished the predetermined count, the clock signal from the clock extraction circuit 42 is sent to the clock terminal 14 by the AND gate 46a. At the same time, the signal from carry detection circuit 45 controls the gate of AND circuit 46 c and sends the data signal from data terminal 15 to transmission circuit 43 via OR circuit 47. The data signal from the data terminal 15 can be transmitted to the reader by the antenna 11. The reader can receive the data from the data terminal 15 together with the identification number (1) 18 in the memory circuit 17a.

  FIG. 5 shows one embodiment of the present invention. This figure shows the internal structure of the IC chip 21 having terminals for connecting to other IC tags. The voltage from the power supply terminal 22 is supplied to the counter circuit 51 and the memory circuit 26a. A recognition number (2) 26 is stored in the memory circuit 26a. A clock signal from the clock terminal 23 is supplied to the counter circuit 51. The counter circuit 51 drives the memory circuit 26a in which the identification number (2) 26 is stored, and the memory circuit 26a sequentially transmits the data of the identification number (2). At this time, the counter circuit 51 is counted up by the clock signal, and the count value of the counter circuit 51 corresponds to the memory address of the memory circuit 26a. Data from the memory circuit 26 a is sent to the data terminal 24. The ground 52 is connected to the ground terminal 25. By connecting the power terminal 22, clock terminal 23, data terminal 24, and ground terminal 25 of the IC chip 21 to the power terminal 13, clock terminal 14, data terminal 15, and ground terminal 16 of the IC tag chip 12, the IC chip 21. The data of the identification number (2) 26 can be transmitted to the reader via the IC tag chip 12.

  The IC tag chip 12 is attached to a cable terminal of a nuclear power plant or the like, and the IC chip 21 is attached to a terminal block. At the same time as a cable terminal of a nuclear power plant or the like is coupled to the terminal block, the affixed IC tag chip 12 and the affixed IC chip 21 are coupled. Further, at the same time when the nuclear cable terminal is separated from the terminal block, the attached IC tag chip 12 and the attached IC chip 21 are separated.

  When the affixed IC tag chip 12 and the affixed IC chip 21 are combined, when the reader performs a reading operation, the reader first reads the identification number (1) present in the IC tag chip 12, and then continuously. Thus, it becomes possible to read the identification number (2) existing in the coupled IC chip 21.

  If the reader performs a reading operation when the attached IC tag chip 12 and the attached IC chip 21 are separated, the reader first reads the identification number (1) existing in the IC tag chip 12, and then continuously. The identification number (2) existing in the coupled IC chip 21 is read, but since the IC tag chip 12 and the IC chip 21 are separated, the identification number (2) existing in the IC chip 21 is separated. ) Cannot be read by the reader.

  FIG. 6 shows one embodiment of the present invention. This figure shows a read bit format. FIG. 6A shows a bit format of data read by the reader when the attached IC tag chip 12 and the attached IC chip 21 are separated. FIG. 6B shows a bit format of data read by the reader when the attached IC tag chip 12 and the attached IC chip 21 are combined.

  The number of bits of the identification number (1) and the identification number (2) is arbitrary, but the number of bits such as 32 bits, 64 bits, 128 bits, etc. is selected. In the case of a 128-bit example, in FIG. 6A, the 128-bit identification number (1) is read first, and then the reader tries to read the 128-bit identification number (2), but is pasted. When the IC tag chip 12 and the attached IC chip 21 are separated, the identification number (2) is not transmitted from the IC tag chip 12, so the reader recognizes that all 128 bits are “0” (all 0). Thus, the reader can automatically recognize that the IC tag chip 12 is separated from the IC chip 21. In FIG. 6B, the 128-bit identification number (1) is read first, and then the reader reads the 128-bit identification number (2).

  FIG. 12 is a diagram illustrating an example of a waveform of a signal between the IC tag chip 12 and the IC chip 21. The signals at the clock terminals in FIG. 12 are signals at the clock terminals 14 and 23 from the coupled IC tag chip 12 to the IC chip 21. Further, the signal at the data terminal in FIG. 12 is a signal at the data terminals 24 and 15 from the coupled IC chip 21 to the IC tag chip 12. FIG. 12 shows an example in which “0”, “1”, “0”, “1”, “0” are transmitted in synchronization with the signal at the clock terminal.

  FIG. 7 shows one embodiment of the present invention. This figure shows the configuration of a management system (wireless IC tag system) comprising a database, reader, IC tag, and the like. Cables for nuclear power plants and the like are coupled to the terminal block at high density. For this reason, it is impossible to individually irradiate electromagnetic waves in order to identify individual cables. In this embodiment, by irradiating a plurality of cables, the situation of the cables is recognized efficiently at the same time.

  In the database 71, logical connection states of all cables are registered. For example, the connection state is recorded in association with each ID (recognition number) of the IC tag attached to the cable. The reader 72 and the database 71 communicate with each other by wire or wireless. The reader 72 has a reader antenna 73 and has a function of irradiating the IC tag chip with electromagnetic waves. FIG. 7 shows a state where three cables 74a to 74c are coupled to the terminal block. In practice, the number of connection points between the cable and the terminal block may reach 100,000 or more in a set of nuclear power plant equipment.

  An IC tag 75a is affixed to the cable 74a, and an IC chip 76a is affixed to the terminal block 77a. When the cable 74a is coupled to the terminal block 77a, the affixed IC tag 75a and the affixed IC chip 76a are coupled. An IC tag 75b is attached to the cable 74b, and an IC chip 76b is attached to the terminal block 77b. When the cable 74b is coupled to the terminal block 77b, the affixed IC tag 75b and the affixed IC chip 76b are coupled. An IC tag 75c is affixed to the cable 74c, and an IC chip 76c is affixed to the terminal block 77c. When the cable 74c is coupled to the terminal block 77c, the affixed IC tag 75c and the affixed IC chip 76c are coupled. Note that the IC tag and the IC chip attached to the cable and the terminal block may be reversed. That is, an IC chip may be attached to the cable, and an IC tag may be attached to the terminal block.

  For example, the three cables 74a, 74b, and 74c are simultaneously irradiated with electromagnetic waves from the reader antenna 73. When the cables 74a, 74b, and 74c are selected one by one according to a predetermined congestion control algorithm, the combination of the IC tag 75a and the IC chip 76a attached to the three cables according to the format according to FIG. Data of the combination of the tag 75b and the IC chip 76b and the combination of the IC tag 75c and the IC chip 76c can be read. These data are compared with information in the database 71. If it is different from the compared data, it is recognized that the combination is incorrect. If the cable is separated from the terminal block, it is read in the format of FIG. 6A, so that it can be recognized that it is instantaneously separated. Also, for example, in a certain control circuit, when it is recognized that a specific item is separated on the database even though the cable is connected to the terminal block, among all the IC tag chips and IC chips, It can be determined that this particular chip is faulty.

  FIG. 8 shows one embodiment of the present invention. This figure shows an operation flow of a management system (wireless IC tag system) for confirming separation and coupling of cable connections. In this management system, the reader 72 reads a 256-bit identification number in accordance with the format of FIG. 6 in order to see the status of the cables 74a to 74c by predetermined congestion control. At this time, if the latter 128 bits are all “0”, it is recognized that the cables 74a to 74c and the terminal blocks 77a to 77c are separated, and if the latter 128 bits are not “0”, the cables 74a to 74c. It is recognized that the terminal blocks 77a to 77c are coupled.

  Next, the data read by the reader 72 and the data in the database 71 are collated. As a result of this collation, if the connection state is recognized but does not coincide with the data in the database 71, it is recognized that the connection is different between the cable and the terminal block, and a correction work instruction is issued. This correction work instruction is performed by, for example, displaying the screen on a display screen of the management system. According to the correction work instruction, it is manually reworked. The database 71 may store work information in addition to the connection information between the cable and the terminal block, display the work information on the screen, and perform the work in accordance therewith. It is also possible to simply notify an alarm.

  The above operations and reading operations are repeated until the reading data of the reader matches all the information in the database.

  In the conventional case, since collation with the database is only key input or visual confirmation, erroneous confirmation occurs, which is inefficient. The present invention can significantly improve these confirmations.

  Next, an example of the congestion control algorithm will be described. Congestion control is control for reading a plurality of IC tags in the same radio wave area. In the following, although not limited to this, for the sake of easy understanding, a case where there are two IC tags will be described as an example.

  Congestion control methods include time slot, binary tree, binary search, frequency division multiplex reading, and the like.

  In the time slot, the IC tag A and the IC tag B take a time difference and transmit an identification number to the reader. A pseudo random number generation circuit is provided in the IC tag chip, and a command is retried upon collision.

  In the binary tree, an IC tag A or IC tag B is read independently by a reader specifying a classification of recognition numbers. A division comparison circuit is provided in the IC tag chip to receive a command and repeatedly transmit a recognition number.

  In the binary search, the identification numbers of the IC tag A and the IC tag B are read one bit at a time without overlapping. An overlap confirmation control circuit is provided in 1-bit units in the IC tag chip, and the identification number is transmitted in 1-bit units.

  In frequency division multiplex reading, IC tag A and IC tag B transmit identification numbers simultaneously in different frequency bands. A pseudo random number generation circuit is provided in the IC tag chip, and a command is retried upon collision.

  FIG. 25 shows a specific IC tag, a communication method in a reader, and a congestion control method. FIG. 25 shows a case where two IC tags A and B are present in the effective radio wave area. Further, in this embodiment, for the sake of easy understanding, the counter in each IC tag shows a case of 2 bits.

  When the clock pulse from the reader starts, the IC tag A and the IC tag B simultaneously set an initial value of a predetermined page number in the counter. This initial value is set in advance so as to be different between the IC tags. In this embodiment, the page number is “01” for the IC tag A and “11” for the IC tag B. The reader issues clock pulses at short intervals and tries to read the memory data of the IC tag. However, since the counter in each IC tag is not yet “00”, each IC tag does not transmit the memory data. Then, since the data does not come, the reader determines that there is no IC tag in operation, stops sending clock pulses at short intervals, and sends clock pulses at long intervals. Then, each IC tag counts up the page number by “+1” and becomes “10” for IC tag A and “00” for IC tag B. At this time, the IC tag B sets the operation switching flip-flop, and sends the memory data to the reader by the next short-interval clock pulse. When it ends normally, the reader also issues a long-interval clock pulse, and the IC tag A counter becomes “00”, and the IC tag A sends out the memory data.

  As shown in this example, IC tag A and IC tag B send memory data without overlapping, and the reader is performing an operation of turning pages at a high speed by a clock pulse with a long interval. The control reading time is shortened.

  When the initial values are accidentally overlapped, a plurality of values that can be set as initial values may be stored in advance. In this case, an initial value may be reset on the IC tag side when congestion occurs.

(Embodiment 2)
In the second embodiment, a modification of the IC chip 21 will be described. The IC chip 21 also functions as a wireless IC tag chip.

  FIG. 9 shows one embodiment of the present invention. FIG. 9 is an internal drawing of an IC chip having an antenna and a connection terminal.

  Although the IC chip 21 shown in FIG. 5 is attached to the terminal block, the identification number (2) 26 existing inside the IC chip alone cannot be read. Therefore, FIG. 9 shows a configuration in the IC chip for when the identification number (2) 26 existing in the inside is to be read wirelessly by the IC chip alone.

  As shown in FIG. 9, the antenna 11 is connected to the rectifier circuit 41, the clock extraction circuit 42 demodulates the clock signal, and this clock signal enters the counter circuit 51 via the OR circuit 47. The counter circuit 51 drives the memory circuit 26 a, and the memory circuit 26 a sends the memory data (recognition number (2) 26) to the transmission circuit 43. The transmission circuit 43 transmits memory data to the reader via the antenna 11. The OR circuit 47 has a function of receiving a signal from the clock terminal 23.
