The present invention relates to an operation state detecting device for a control machine using an IC tag, a rotary switch mechanism, and a detection adapter, and more particularly to a state in which an IC tag is used to identify a state of an operation switch or a switch position using a non-contact type. The way to control the operating state of the machine.

In a control machine equipped with a mechanical switch, a switch, an operating lever, etc., in order to maintain their operating state, for example, in an industrial power supply system, it is necessary to stably maintain a large power supply/opening switch (also In the switch state of the plurality of switches, there is a cam-operated switch mechanism as a mechanical means (see Non-Patent Document 1).

Patent Document 1 discloses an IC tag communication technique in which a small IC tag is erected on a metal surface and a metal surface is used. Patent Document 2 discloses a technique in which a small IC tag that is erected is placed in a state of being closely gathered or side by side on a mounting surface, and when one of the target IC tags is to be communicated, a half wavelength is disposed near the IC tag. A metal rod of a size that is electromagnetically coupled to the IC tag directly below it, thereby forming a dipole antenna so that it can communicate with an IC tag that cannot be responded to when it is alone. In this technique, a dipole antenna that can be transmitted to a distant type of electromagnetic wave has a central portion that becomes a maximum point of a high-frequency current that resonates with a communication electromagnetic wave, and a magnetic line that is proportional to its size is high. Frequency current The direction is orthogonal, and the ring is wound in accordance with the right-hand rule, and the annular magnetic line is electromagnetically coupled to the closest IC tag, thereby making the IC tag that cannot be responded alone become an active state that can be communicated. Therefore, the IC tag disposed at a distance that cannot be electromagnetically coupled to the dipole antenna becomes a separate state and becomes an inactive state (resting state) that cannot be responded to.

Conventional control devices such as operation switches or control switches, etc., while reading the values of the operation knobs or knobs, visually recognize various misreadings, and the possibility of causing human error is a problem. Examples of misreading are misunderstandings of the values indicated by the handles or knobs, misrepresentation of characters and marks that are easily mistaken, and misreading due to peeling or blurring of values. In addition, in order to prevent misoperation, the handle or knob may be removed as a safety measure, but the handle or knob may be incorrectly installed and misread. Moreover, when the treatment of removing the handle or the knob is applied, there is also a problem of difficulty in reading.

In the invention described in Patent Document 1 or Patent Document 2, an IC tag can be installed or assembled on a metal surface, but it is not fully considered in a control device including a mechanical switch or a switch such as a cam switch. How to confirm the operating state; in other words, whether the operated switch is in the state of being put in or off, or which position is the operating state of the switch position when the cam switch is operated by the handle, and cannot be confirmed in a non-contact manner.

According to the invention of Patent Document 3, the IC tag is provided or assembled to a metal surface or the like, and in a control device including a mechanical switch or a switch such as a cam switch, the operation state can be confirmed in a non-contact manner. However, since the small IC tag is erected on the metal surface by the erecting method, the device structure for assembling the IC tag is limited in size. Moreover, since the IC tag is erected on the metal surface, When the reader/writer is approaching, the built-in antenna of the reader/writer is activated, and the magnetic lines of force are electromagnetically coupled directly through the IC tag, so that even the IC tag in the resting state becomes Active state, and the possibility of false detection of mis-communication.

That is to say, an IC tag having a ring-shaped internal antenna and being difficult to respond alone, when it is erected on the mounting surface, the mounting surface must be a metal surface or a conductor surface, the conductor surface must have a sufficient size compared to the wavelength, or It must be at the time of communication to promote the reflection or resonance of the communication. If the mounting surface is non-metallic or insulator, then the effect of the communication will disappear and it will not be easy to communicate. When the IC tag is placed upright on the metal surface, the protruding height from the mounting surface becomes large, which hinders the smoothness of assembly, and is a problem. Further, when the IC tag which is difficult to respond alone is disposed in parallel on the metal surface, that is, when the ring surface of the loop antenna inside the IC tag is disposed in parallel on the metal surface of the mounting surface, the protruding portion on the mounting surface is reduced. However, it is a problem that the reverse high-frequency current flows in the metal surface and the electromagnetic waves used for communication cancel each other and become uncommunicable.

Further, in the invention of Patent Document 3, it is configured such that an IC tag which is difficult to respond alone and which is smaller than a half-wavelength size is closely gathered or arranged, and only one target IC tag is selected therefrom. Therefore, when the dipole antenna rod to be detected is placed directly above the target IC tag and electromagnetically coupled thereto, it is necessary to arrange the IC tag outside the target away from the dipole antenna bar and outside the electromagnetic coupling range. That is to say, when the target IC tag is indicated and selected by the dipole antenna rod, there must be an IC tag space for inserting one IC tag directly under the bar, and the device structure of the non-contact detecting portion It is a problem that cannot be miniaturized.

An object of the present invention is to provide an operation state detecting device for a control device using an IC tag, a rotary switch mechanism, and a detection adapter that intersects with an IC tag indicated and selected by a detecting portion of the detecting adapter It will not be inadvertently electromagnetically coupled with other IC tags, and can reliably perform 1-to-1 communication.

According to a typical example of the present invention, an operation state detecting device for a control device using an IC tag includes a plurality of IC tags, and the control device is associated with an operation state of the control device and is mounted on the same mounting surface. And a detecting adapter, the relative positional relationship with the plurality of IC tags changes according to the operating state of the control device; the plurality of IC tags, the torus of each of the IC tags are arranged in parallel In the mounting surface, the detecting adapter is configured to detect the loop antenna of the IC tag and the radiating antenna system connected to the loop antenna, and the toroid of the loop antenna of the detecting adapter In response to the respective operating states of the control device, the toroidal surfaces of the corresponding one of the IC tags are aligned in parallel with each other, and the magnetic lines formed by the radiation antenna of the detecting adapter are configured not to Through the torus of each of the aforementioned IC tags.

According to the present invention, it is possible to provide a method of detecting adapters The IC tag instructed and selected by the detection unit performs communication, and does not inadvertently electromagnetically couple with other IC tags, and performs one-to-one communication reliably. By detecting the IC tag, the installation is known in a non-contact manner. The state of the device or appliance.

According to a representative embodiment of the present invention, the loop antenna surface of the detecting portion of the adapter is detected to be parallel to the shape of the torus of the IC tag to be detected. The annular inner antenna annulus of the IC tag to be inspected is disposed in parallel with respect to the mounting surface, so that the protruding portion of the protruding mounting surface is reduced. The transmission portion of the detecting adapter is composed of a parallel two-wire transmission line made of a hard conductor, and is connected to the detecting portion, and tries to prevent the high-frequency current flowing through the transmitting portion from being generated in the discontinuous portion. The required reflection is performed, and the target IC tag can be surely subjected to a one-to-one non-shake instruction operation. The radiation antenna portion connected thereto is a dipole-based antenna that maximizes resonance at a half wavelength, and the maximum point of the high-frequency current at the center portion is connected to the transmission line. Further, the radiation antenna portion is covered with a strong dielectric body, and the antenna portion connected to the reader/writer device is attached by means of a single operation, such as a devil's felt. The IC tags are arranged in parallel. When the loop antenna surface of the detecting portion is parallel to the IC tag, a strong electromagnetic coupling relationship is established. On the other hand, the IC tag other than the IC tag electromagnetically coupled to the detecting unit is excited by the high-frequency current flowing through the dipole antenna even if it enters the dipole antenna of the radiation antenna portion of the detecting adapter, for example. The magnetic field lines extend to the IC tag directly below the dipole antenna Since the IC tags are arranged in parallel, they do not penetrate the loop antenna inside the IC tag, but become parallel in parallel, and cannot be electromagnetically coupled. That is to say, it is possible to provide a method of detecting the adapter and the IC tag and its setting method, and communicating with the IC tag indicated and selected by the detecting portion of the detecting adapter, without inadvertently and other The IC tag is electromagnetically coupled to perform a one-to-one communication, and the state of the installed device or appliance is known in a non-contact manner by detecting the IC tag.

According to a representative embodiment of the present invention, the detecting adapter is connected to a rotating shaft of the switch, the detecting adapter is a dipole antenna as a supplementary antenna, and a transmitting portion connected thereto, and a transmitting portion The loop antenna connected to the detecting portion is integrally formed; and the small IC tag for detecting the position of the switch by detecting the detecting portion 152 of the adapter 15 is provided on the same circumference around the axis of the rotating shaft. . That is to say, the small IC tag is sequentially rotated to directly below the detecting portion of the detecting adapter that rotates in conjunction with the rotation of the switch. The IC tag has an inner ring shape or a ring-like configuration, and the ring faces of the loop antenna are arranged in parallel or substantially parallel in an insulated state (referred to as parallel arrangement in the present specification) on a metal mounting surface. By doing so, the detecting adapter can communicate with the small tag 1 to 1 directly below the detecting portion of the detecting adapter rotating around the rotating shaft. By means of the communication, the IC tag reader obtains the information of the IC tag (pre-set different information for each configured IC tag), and from the acquired information, the operating position of the switch can be recognized.

In addition, as an IC tag having a ring shape or a ring-like structure inside the IC tag, other methods of mounting on the mounting surface are still standing upright. The setting of the mounting surface (referred to as the upright setting in this booklet). In a representative embodiment of the present invention, a specific small IC tag that is disposed in parallel on a metal mounting surface is characterized by a one-to-one communication with the rotating detection adapter.

Further, in the present invention, the frequency band of the radio wave used for communication is a UHF band or a microwave band.

Specific embodiments of the invention are described below.

[Example 1]

First, a first embodiment of the present invention will be described with reference to the drawings.

1 is a schematic cross-sectional view showing a configuration of a cam switch as a rotary switch mechanism (hereinafter, a rotary switch mechanism is referred to as a cam switch), which is suitable for realizing an operation state detecting device of a control machine using the IC tag of the present invention. . 2A is a schematic perspective exploded view of the cam switch of FIG. 1. 2B is a schematic rear view of the IC label holding panel of FIG. 1. The operating state detecting device of this embodiment is configured to detect an operating state of the electrical switch, that is, the cam switch 1. The cam switch 1 includes a cam switch main body portion 12, and a handle 17 is attached to the switch shaft 11 so as to drive a switch mechanism provided therein by a rotary motion through a switch shaft (rotary shaft) 11 (refer to Patent Document 1). O-O' of Fig. 2A indicates the central axis of rotation of the switch shaft 11. The operation state of the cam switch main body 12 is visually recognized by a scale or a representation (not shown) imprinted on the non-metal visual panel 20. The spacer 16 for position adjustment is interposed on the back surface of the visual panel 20 to detect the mating The auxiliary device (auxiliary antenna) 15 is attached to the shaft 11 extending from the cam switch main body portion 12. That is to say, the detecting adapter 15 is mounted in the cam switch and rotates simultaneously with the shaft 11, and is a built-in detecting adapter. In the example shown in Fig. 1, a dipole antenna is used as the detecting adapter 15. Further, the detecting adapter 15 is electromagnetically insulated from the shaft 11 in order to operate as a dipole antenna.

The built-in type detecting adapter 15 includes a radiation antenna 151, a detecting unit 152, a resin-made insulating base material 153 that coats the radiation antenna, and a transmission line 154 that connects the radiation antenna 151 and the detecting portion 152. The planar shape is slightly T type. Further, a hole 150 is provided in the insulating base member 153 for fixing the detecting adapter 15 to the shaft 11.

The radiation antenna 151 is a dipole-based antenna such as a folded dipole or a half-wave butterfly. If the length is L, then L = λ / (2 ). Where λ is the wavelength of the electromagnetic wave to be communicated with the IC tag, and ε is the relative dielectric constant of the insulating substrate 153. When a radio wave of a UHF band is used, a material having a high relative dielectric constant is used. For example, when ε is 10, L=5 cm is reserved. When a radio wave of a microwave wave band is used, a material having a low relative dielectric constant such as a foamed resin is used. For example, when ε is 1.4, L=5 cm is predetermined. The detecting unit 152 has the same size as the internal loop antenna of the small IC tag, and is configured, for example, by a loop coil having an outer diameter of about 5 mm. The toroidal surface of the toroidal coil is parallel to the mounting surface of the small IC tag 10, and in this embodiment is parallel to the metal surface, that is, the surface of the backing plate 13; in other words, it is at a right angle with respect to the central axis of rotation of the shaft 11. Further, the dipole base antenna of the radiation antenna 151 is also parallel to the face of the back plate 13. However, it is preferable that the toroidal coil surface of the detecting portion 152 is located as close as possible to the small IC tag 10 in a range that does not come into contact with the small IC tag 10 when the axial direction is rotated, for example, a distance of 1 mm or less. On the other hand, when the mounting surface of the small IC tag 10 is a metal surface, the dipole base antenna of the radiation antenna 151 is preferably as far as possible in the axial direction, for example, about 2 mm to 5 mm. Therefore, the built-in type detecting adapter 15 can also be seen from the cross-sectional view of FIG. 1 in that the transmission line 154 that connects the radiation antenna 151 and the detecting portion 152 has a curved portion or a step portion; the detecting portion 152 It is rotated at a position closer to the side of the small IC tag 10 than the dipole base antenna.

The transmission line 154 may be constituted by any one of a balanced two-wire, or a twisted pair, or a coaxial line or a coaxial tube. 2A is transmitted in a balanced double line, and the length of the transmission line 154 is preferably 0 to less than λ/4, or slightly an integral multiple of λ/2, and avoids the λ/4 length. The transmission line 154 is made of, for example, stainless steel wire, the line thickness is 1.0 mm, and the interval between the double lines is 1.0 mm; when the radio frequency of the UHF band is 953 MHz, the length is between 1 cm and 5 cm to avoid λ/4. When the frequency of the microwave wave band is 2.45 GHz, to avoid the λ/4 length, it is about 1 cm to 2 cm, which is the length that can be assembled in two cases.

The detecting adapter 15 is rotated in a circular space 141 excavated in the IC label holding panel 14, and a plurality of small IC tags 10 for detecting the position of the detecting adapter 15 are formed in the concave portion 142 on the back side thereof. The system is disposed on the same circumference centered on the axis of the shaft 11. That is, as shown in FIG. 2B, on the back side of the IC label holding panel 14, sandwiched between the mounting surfaces (metal back sheets) 13 for accommodating and holding a plurality of small The plurality of recesses 142 of the IC tag 10 are disposed at equal intervals on the same circumference. Each of the small IC tags 10 is insulated and fixed to the surface of the metal back plate 13 at the position of the concave portion 142 by an adhesive or the like. The cam switch main body portion 12, the IC tag holding panel 14, and the handle 17 are made of an insulating material such as a resin material. Further, in the actual device, the panel (not shown) of the switchboard is located between the metal back plate 13 and the cam switch body portion 12. In order to prevent malfunction, the handle 17 may be removed before the next driving operation once the driving operation.

Further, the reason why the back plate 13 of the mounting surface is made of metal is to make the small IC tag's resting state more reliable, and to provide a function of shielding electromagnetic waves. Therefore, if the shielding function is achieved by a switchboard panel or other insulating material or the like, the backing plate 13 of the mounting surface may also be a resin plate. In this case, in connection with the radiation line 151 and the transmission line 154 of the detecting portion 152, miniaturization can be prioritized, and the bending portion or the step portion can be made smaller, but in order to avoid direct connection between the radiation antenna 151 and the IC tag Electromagnetic coupling, how many distances are ideal.

As shown in FIG. 1, the metal back plate 13, the IC tag holding panel 14, and the visual panel 20 each have a hole in the center, and these members are in a state where the small IC tag 10 and the detecting adapter 15 are located at a predetermined position. Next, their outer peripheral portions are fixed to the cam switch body portion 12 with bolts 23. In other words, each of the small IC tags 10 is sandwiched between the IC tag holding panel 14 and the metal back plate 13, and is fixedly held at the predetermined position. On the other hand, the detecting adapter 15 is fixed to the shaft 11 while being held to be rotatable in the space 141 of the IC label holding panel 14. 18 is The antenna unit and 22 of the IC tag reader 19 are state recognition processing units, and are processing units for hardware or software that process the detected IC tag information and recognize the state thereof. The IC tag reader 19 and the state recognition processing unit 22 are communicable via a communication cable or wirelessly.

Fig. 3 discloses an example of a small tag 10 disposed on a metal surface (backing plate 13 in this embodiment). The small tag 10 is composed of a planar toroidal coil 102 that is connected to the IC wafer 101, an insulating base material 103, and the like. 3(a) shows that the toroidal coil 102 is wound one turn, and (b) that the toroidal coil 102 is wound in a plurality of turns. The annular inner antenna annulus of the IC tag to be inspected is disposed in parallel with respect to the mounting surface, so that the protruding portion of the protruding mounting surface is reduced.

Further, the configuration of the small-sized tag 10 is not limited to this example. For example, it is also possible to implement a ring-shaped integrated circuit formed of a dipole antenna or the like in place of the toroidal coil. In this case as well, the toroidal surface of the IC tag formed by the loop-integrated circuit is disposed in parallel with respect to the mounting surface.

The small tag 10 is disposed on the side opposite to the IC wafer 101 (the lower side in FIG. 3) and is in contact with the metal back plate 13. The size D of the small tag 10 is roughly 1/10 or less of the wavelength of the electromagnetic wave used for the IC tag at the time of communication. For example, in an IC tag using a microwave band having a frequency of 2.45 GHz, it will be a size of 12 cm or less. The small tag in this state does not have sufficient sensitivity when it is alone, and usually cannot directly communicate with the IC tag reader.

4A is an IC tag reader, a built-in type detection adapter, and an IC The relationship diagram of the label. The IC tag 10 having the ID code communicates with the IC tag reader 19 through the detecting adapter 15. The IC tag 10 has no built-in power source, that is, a passive tag, and the electromagnetic wave received from the IC tag reader 19 via the antenna 102 is temporarily converted into a DC power source by the rectifier 1012 of the IC chip 101 to operate as an energy source. In response to the ID code held by the signal processing unit 1015, the electromagnetic wave modulated by the modulator 1011 is reflected from the antenna 102 to be transmitted. In the IC tag reader 19, the transmitter 191 and the receiver 192 are connected to the antenna 18 via a circulator 193.

Here, when the antenna unit 18 of the IC tag reader 19 radiates the electromagnetic wave 21 to the cam switch 1 and performs communication, only the signal from the IC tag 10 can be obtained, and the IC tag 10 is located at the detection adapter 15 The position of the detecting unit 152 is opposite to each other. The signal here is mainly sent to the state recognition processing unit 22 by the signal received by the IC tag 18, and the state recognition processing unit 22 is connected to the IC tag reader 19 in a hardware or software manner. In the state recognition processing unit 22, the demodulation/decoder 22A converts the high frequency into information such as a unique ID code for each original IC tag. The information is sent to the ID code mapping information comparator 22B. In the ID code mapping information comparator 22B, the mapping information is preset, and the mapping information is combined with a plurality of cam switches (1a~) disposed on the switchboard (or in the factory where the switchboard is installed). In 1n), the ID code of each IC tag and the IC tag having the ID code belong to which one, and which position of the cam switch to be mounted, and which position is the cam switch. By comparing with the mapping information In contrast, when the ID code is successfully received, the cam switch is determined to be able to recognize the operating state of the cam switch.

In the state memory unit 22C, the ID code of the cam switch and the operation state of the cam switch are stored in accordance with the respective cam switches. In the setting target value memory unit 22D, the operation state of each cam switch in the case where the setting is correctly set is set in advance. The state determining unit 22E compares the content of the state memory unit 22C with the content of the set target value memory unit 22D, and as a result, determines whether the state of each cam switch is correct. The result is output by the interface unit 22F such as a display.

Further, when the visual panel 20 is formed as a transparent plate, the detection adapter 15 on the inner side can be used as a built-in pointer, and the position of the switch can be easily known from the position of the built-in pointer, that is, Notch position. In this way, even if the handle or the knob is removed, the structure in which the built-in pointer is difficult to remove can be added as a means for knowing the position of the notch from the outside. Since the built-in pointer is connected to the shaft that operates the switch or the switch, even if the handle or the knob is removed, the built-in pointer can function as a structure for indicating the position of the notch.

In addition, when the detecting adapter 15 that performs the dipole antenna operation is rotated so that the IC tag is not present directly below it, no communication is established with any of the IC tags. Therefore, the IC tag must be placed at one of the positions positioned by the notch mechanism of the cam switcher 12. However, when the detecting adapter 15 that performs the dipole antenna operation is rotated, it should be configured such that only one IC tag is located directly below it.

Next, how to identify the switch position of the rotary switch, and How to assemble an IC tag to a rotary switch.

FIG. 4B is an explanatory diagram showing the relationship between the small IC tag in which the loop antenna ring surface inside the IC tag is arranged in parallel on the mounting surface, and the detecting adapter. In addition, FIG. 5 is an explanatory diagram of the positional relationship between the detecting adapter and the small IC tag in FIG. 4B.

The IC tag 10 has a short receiving distance and cannot communicate with the IC tag reader 19. However, when the detecting portion 152 of the detecting adapter 15 is directly above, the opposing IC tag 10 is electromagnetically coupled to the detecting portion 152 of the detecting adapter 15 by electromagnetic induction, thereby achieving a high sensitivity state. Sufficient to communicate. The IC tag arranged in parallel on the circumference of the mounting surface is electromagnetically coupled to the loop coil 152 of the detecting portion, but is connected to the radiation antenna 151 of the detecting adapter, for example, composed of a dipole antenna, due to magnetic lines of force. The toroidal surfaces of the IC tags are arranged in parallel such that the magnetic lines of force passing through the toroidal coil 102 are absent or less than substantially negligible, so that they cannot interact and substantially electromagnetically couple. In addition, when the toroidal coil 102 is in an approximate position with respect to the mounting surface and is not parallel, that is, inclined, the toroidal surface of the IC tag and the dipole antenna may be electromagnetically coupled. In order to surely exclude such a situation, as described above, a bending portion or a step portion is provided on the transmission line 154 contacting the radiation antenna 151 and the detecting portion 152, so that the radiation antenna 151 is as far as possible from the toroidal surface of the IC tag, so that the electromagnetics of the two are made. The coupling is small enough to be negligible.

Therefore, corresponding to the operation of the rotary switch, only the IC tag indicated by the detecting portion is selected, and electromagnetically coupled to the loop coil 152 of the detecting portion, and one-to-one communication can be performed.

That is, as shown in FIG. 5(a), the IC tag 10 is disposed in parallel on the metal mounting surface 13, and the ring surface 158 of the loop antenna of the detecting portion 152 is parallel to the IC tag 10, which is strong. Electromagnetic coupling relationship. According to electromagnetics, the magnetic force line Φ1 radiated from the detecting unit 152 of the detecting adapter 15 is electromagnetically coupled to the toroidal surface 108 formed by the loop coil 102 of the IC tag 10, and is communicable.

On the other hand, as shown in FIG. 5(b), the magnetic field line Φ2 excited by the IC tag flow electromagnetically coupled by the detecting unit 152 extends to the IC tag 10 directly below the radiation antenna 151, but the IC tag 10 is attached. Since the magnetic lines Φ2 are parallel to the toroidal coil 102A inside the IC tag 10, they are not electromagnetically coupled. That is to say, only the IC tag instructed and selected by the detecting unit 152 of the detecting adapter is communicated, and the situation in which the IC tag other than the IC tag is inadvertently electromagnetically coupled is prevented.

In this way, one-to-one communication can be surely performed between the detection adapter and the plurality of IC tags. By providing such an IC tag to the cam switch, the state of the attached cam switch device or appliance can be accurately known without contact and without erroneous detection.

As a comparative example, as shown in FIG. 6, when the annular antenna ring surface inside the IC tag 30 is erected on the mounting surface (ie, the surface of the back plate 13), the detection of the small IC tag 30 and the detecting adapter 15 is performed. The relationship between the coil and the radiating antenna. In this installation method, as shown in FIG. 6(a), a part of the magnetic flux Φ1 radiated from the detecting coil of the detecting portion 152 of the detecting adapter 15 partially penetrates the loop coil of the IC tag 30. In the torus, the detection coil of the detecting adapter 15 and the IC tag 30 are weakly electromagnetically coupled to be able to communicate.

However, as shown in FIG. 6(b), once the magnetic line Φ2 from the radiation antenna 151 of the detecting adapter 15 extends, it penetrates the annulus 102B of the IC tag 30 directly below the radiation antenna 151, and detects the adapter 15 and The IC tag 30 is electromagnetically coupled and has a risk of communicating with an IC tag other than the IC tag indicated by the detecting unit 152 of the detecting adapter. This example corresponds to, for example, the configuration of the first embodiment of Patent Document 1. In such a conventional technique, the distance h between the detecting adapter and each IC tag is enlarged (the length of the axial direction of the adapter portion in the cam switch 1 is increased), or the reading is lowered. The electromagnetic wave output of the device/writer to reduce the risk of such false detection. According to the present invention, the risk of such erroneous detection can be completely eliminated even if the distance h between the detecting adapter and the IC tag is short (the axial length of the adapter portion of the cam switch 1 is configured to be shorter), It is still possible to correctly perform one-to-one communication with only the IC tag indicated by the detecting unit.

According to the present embodiment, it is possible to provide an operation state detecting device that does not need to touch the handle or the case when the device is controlled to be patrolled or inspected for maintenance or the like even if the switch or the control switch of the control machine is assembled in the control system. Knobs can be used to identify their switch position or representation in a non-contact manner by electromagnetic waves, which has a great effect on reducing human error caused by visual observation and the like.

In particular, according to the present embodiment, it is possible to provide a method of communicating with an IC tag indicated and selected by the detecting portion of the detecting adapter. It is not inadvertently electromagnetically coupled with other IC tags, and the one-to-one communication is surely performed, and the state of the installed device or appliance is known in a non-contact manner by detecting the IC tag.

Further, the annular inner antenna annulus of the IC tag to be detected is disposed in parallel with respect to the mounting surface, so that the protruding portion of the protruding mounting surface is reduced, and smooth mounting can be provided.

Further, the present invention is not limited to the cam switch described above. For example, if the cam switch of the first embodiment is replaced with the rotation state of the locking mechanism of the detecting door, it can be used to detect the operating state of the locking mechanism of the door.

In the first embodiment, the detecting adapter is an inner type detecting adapter fixed to the rotating shaft of the cam switch, but it is also possible to integrate only the components necessary for detecting the function of the adapter to be integrated. Portable inspection adapter for the operator to operate by hand.

Fig. 7 is a schematic perspective view showing a configuration example of a portable type detecting device for a portable type of a portable type detecting adapter according to a second embodiment of the present invention. Here, the plurality of IC tags of the detection object are disposed on a metal or non-metal mounting surface 13, and the mounting surface 13 is rotated or linearly moved; in the case disclosed in FIG. 7, one of the plurality of IC tags The target IC tag is placed on the mounting surface 13 and detected. The detecting adapter 155 includes a radiation antenna unit 151 and a detecting unit 152, and a transmitting unit 154 that connects them. The detecting unit 152 has a loop antenna. pass The feeding portion 154 may be any of a coaxial wire, a balanced double wire, a strip line, a waveguide, and a dielectric rod as long as it is a hard conductor. In the example of Fig. 7, a balanced two-wire transmission line composed of a hard conductor is provided, and the transmission line is configured to be connected to the loop antenna of the detecting portion. In this manner, the transfer portion 154 of the present embodiment is adjusted to have a higher rigidity so as to be able to perform a one-to-one instruction operation with the target IC tag 10 without shaking, and to avoid the high frequency flowing through the transfer portion. The current produces unwanted reflections in the discontinuities. The radiation antenna unit 151 is a dipole base antenna that maximizes resonance at a half wavelength, and the maximum point of the high-frequency current in the center portion is connected to the transmission line of the transmission unit 15. The radiation antenna unit 151 is an antenna that is covered by a strong insulating base material (dielectric body) 153 and can be attached or detached by one operation, such as a devil felt or the like, to be connected to the antenna of the reader/writer device. Connection face 192 of the part. When the toroidal surface of the loop antenna of the detecting portion 152 faces the IC tag on the mounting surface 13 in parallel, even if the mounting surface 13 is made of metal, a strong electromagnetic coupling relationship is established.

That is, when the toroidal surface formed by the loop coil of the detecting portion 152 is parallel to the annular coil annulus of the IC tag 10, the magnetic flux Φ1 is transmitted, and the coil 152 of the detecting portion 152 and the loop coil of the IC tag 10 are electromagnetically coupled. And become a tradable.

On the other hand, in a state where the radiation antenna portion 151 is assembled to the antenna portion of the reader/writer device, the magnetic field line Φ2 excited by the electromagnetic wave around the radiation antenna portion 151 is caused to be in contact with the reader. The radiation antenna 18 inside the writer is electromagnetically coupled without being electromagnetically coupled to the toroidal coil 102 of the IC tag 10 provided on the metal mounting surface 13. therefore, It is sufficiently ensured that the length of the transmission line 154 is ideal, for example, a length of about λ/2 wavelength, or that the magnetic force line Φ2 does not penetrate the loop coil 102 of the IC tag 10, but passes in parallel. That is, it is configured that the magnetic force line Φ1 excited by the detecting portion 152 is only electromagnetically coupled to the IC tag 10, and the magnetic force line Φ2 excited at the radiation antenna portion 151 is only associated with the reader/writer device 19 The internal antenna 18 is electromagnetically coupled.

Next, consider a case where one of the plurality of IC tags arranged on the circumference is detected on the metal mounting surface 13 by using the portable type detecting adapter, for example, for detecting the rotation state. IC tag 10. First, the operator assembles the attachment/detachment means 156 for detecting the adapter to the connection surface 192 of the antenna portion of the reader/writer device 19. As a result, the radiation antenna 151 of the detecting adapter 15 is electromagnetically coupled to the radiation antenna 18 inside the reader/writer 19 via the magnetic force line Φ2. Next, while holding the reader/writer device 19, the position of the detecting adapter is set so that the IC tag 10 to be inspected on the mounting surface 13 and the detecting portion 152 of the adapter are ring-shaped. The coil is such that the antenna ring surface of the detecting portion 152 faces the toroidal loop surface of the IC tag in parallel and electromagnetically couples the two. Since the transmission unit 154 has a structure having high rigidity, the operator can select the target IC tag 10 and perform a one-to-one instruction operation without shaking. In this way, only the IC tag to be detected is selected, and the portable type detecting adapter is electromagnetically coupled with the reader/writer 19 to perform 1-to-1 communication. The interval between the adjacent IC tags 10 is set to a predetermined size, and the magnetic field line Φ1 excited between the loop antenna of the detecting portion 152 of the detecting adapter and the IC tag 10 is micro. By being small, the risk of communication with an IC tag other than the IC tag indicated by the detecting unit 152 can be completely eliminated. Further, the rigid transmission portion 154 ensures a sufficient length between the radiation antenna 151 and the loop antenna of the detection portion 152, so that erroneous detection does not occur. Further, the small IC tag 10 whose sensitivity is too small to be directly detected can be eliminated, whereby the radiation antenna 151 can eliminate the risk of erroneous detection. That is, since the IC tag 10 is disposed in parallel to the metal mounting surface 13, there is no risk that the magnetic force line Φ2 from the radiation antenna 151 of the detecting adapter 15 extends, which penetrates the ring of one of the IC tags 10. On the surface, the detecting adapter 155 is electromagnetically coupled to the IC tag, and communicates with an IC tag other than the IC tag indicated by the detecting unit 152 of the detecting adapter.

As described above, the portable type detecting adapter of the present embodiment is used by being assembled to a reader/writer, whereby various control devices for a plurality of IC tags for position detection are rotated or straight. When exercising, it can be widely used for state quantity detection of operational motion.

[Example 3]

Next, a fifth embodiment of the present invention will be described with reference to Figs. 8 to 12, which is applied to an operation state detecting device of a control device having a disconnecting switch group.

Fig. 8 (a) is a view showing the overall configuration of a system in which an operation state detecting device for controlling a machine of the present embodiment is incorporated. This embodiment is, for example, related to an operation state detecting device of a control machine employed in a circuit breaker system group of a high voltage machine.

In the circuit breaker system group, one base 210 and one movable body 230 constitute one set of switch units 200, and the complex array switch unit is at right angles to the moving direction of the movable body 230 (Z-axis direction in the figure). Directions (Y-axis direction in the figure) are arranged in a row and at the same height to form a circuit breaker group (200-1~200-n) of the circuit breaker system; circuit terminals of the control machine of each switch unit (400, 600) The switch circuit 500 is configured to switch between the relay circuit 500 and the control circuit (controller) 300, and the relay circuit 500 controls the high voltage power supply of the main circuit 700 (1~n) of each specific controlled machine of the switch system. And so on. The base 210 is provided with an IC tag 10A that is configured to be associated with a switch operating state of the control device, that is, the controller 300 or the relay 500 connected to the circuit terminals 400 and 600, for example, is electrically connected, or In an open state. On the other hand, the movable body 230 is provided with one IC tag 10B which is disposed in association with the "state in which the IC tag 10A does not occur simultaneously" with respect to the switching operation state of the control device. For example, the IC tag (first IC tag) 10A of the base 210 is in a closed state, and the IC tag (second IC tag) 10B of the movable body 230 is in an open state.

The IC tag 10A on the base 210 or the IC tag 10B on the movable body 230 and the detecting adapter 155 are configured to be selectable in a one-to-one manner so as to correspond to the respective operating states of the movable body 230, that is, the control is to be used. The main circuit 700 of the controlled machine functions (ON) or disables it (OFF); for example, the movable body 230 is pulled up to cut off the circuit terminals 400 and 600, that is, the main circuit 700 is inactive (OFF) State, or The movable body 230 is pressed into a state in which the circuit terminals 400 and 600 are connected, that is, the main circuit 700 is in an active (ON) state. That is, as in the first embodiment, the position of the IC tags 10A, 10B is detected by the reader/writer 19 and the detecting adapter 155, whereby the contents of the switch units 200 can be read. Operating status.

In this example, the state in which the IC tag does not occur at the same time means that the pull-up identification IC tag 10B appears when the switch is in the pulled-up state, and is detectable. In this state, the IC tag 10A in the pressed state is hidden, so it cannot be detected. On the other hand, in the press-fitting state of the switch, the press-in identification IC tag 10A appears and is detectable. In this state, the IC tag 10B in the pulled-up state is hidden, so it cannot be detected. As such, it is constructed such that only the IC tag that is pulled up and pressed into one of the states will appear, and the other will be hidden. Further, regarding the specific mounting position of the IC tag 10A with respect to the base 210 and the mounting position of the IC tag 10B with respect to the movable body 230, an example will be described later. Further, the configurations of the IC tags 10A and 10B are the same as those of the first embodiment, and are the same as those shown in FIG.

In addition, there are many types of controlled devices, and the number of open circuit breaker groups (200-1 to 200-m) for controlling the power supply of the main circuit 700 thereof is also increased, and the operability is considered, and most of the open circuit switching is performed. The entire system is compactly integrated into a narrow space.

In Figure 8(a), almost all of the switcher units of the open circuit breaker group are located at the lowest position (first position), which corresponds to the closed state of the circuit terminals of the control machine, that is, in the pressed state, the circuit terminal 400 and 600 The switch state 200-m is in the open state of the circuit terminal of the control machine, that is, in the pulled-up state, the cut-off state of the circuit terminals 400 and 600 (second position, = completely open or disassembled state). In addition, the switch unit can also be held at an intermediate position (third position) of the first and second positions.

The operation state of such a switch unit can be grasped to some extent by visual inspection by confirming the height or disassembly of each switch unit. However, when the number of switch units increases, the control content is diversified, and the switches of the switch unit are also different, it is necessary to grasp the operation state more correctly and ensure the safety of the operation.

In this embodiment, a pair of IC tags are assembled in each switch unit, and the positions of the plurality of IC tags disposed in a narrow space are not detected by mistake; by adopting such a configuration, the switch is not located. Exclusion of the situation in the middle position, and the position of each switch unit, or even the correct information of the operating state, can be identified in a non-contact manner by electromagnetic waves. In this way, it is possible to provide an operation state detecting device which has a great effect on reducing human errors caused by visual observation or the like. In addition, as a means of detecting the operation state, a thin planar IC tag is used, whereby it can be smoothly mounted.

Alternatively, a pen reader/writer integrated with a reader/writer and a detection adapter may be used instead of the above-described portable reader/writer 19 and detection adapter 155. .

Fig. 8 (b) is a view showing an example of a pen type reader/writer 19 which can be used in the operation state detecting device for controlling the machine of the present embodiment. Pen reader / The writer 19 includes a control unit and a power supply unit provided inside the main body, and a display unit and an operation unit (not shown) provided on the surface of the main body, including the operation lamp number. The control unit is composed of a computer and a program, and further includes a communication unit that communicates with the outside and a small antenna 152 that corresponds to the loop antenna of the detection unit. The first IC tag (closed state) and the second IC tag (on state) are detected by the small antenna 152 at the tip end of the reader/writer 19, and the result is the reader/writer. The internal computer processes it or sends it to the communication status recognition processing unit 22 via the communication unit for external processing. The communication department is compatible with wireless communication such as cable or Bluetooth (registered trademark).

Next, the configuration of the switch unit 200 will be described in further detail with reference to FIGS. 9 and 10.

Fig. 9(A) is a front view of the base 210, and Fig. 9(B) is a side view of the base. 10(A) is a front view of the movable body 230, and FIG. 10(B) is a side view of the movable body.

As shown in FIG. 9, the base 210 has a resin-made mounting board portion 211 and a back plate portion 212, and is integrally provided to protrude from the back plate portion, and slides the movable body 230 in the vertical line (A-A') direction. Guide portion 213. Further, the inner side of the guiding portion 213 constitutes a guiding groove 214 having the same height as the back plate portion, and a horizontally extending stopper 223 is provided at a central portion of the guiding groove 214, and extends upward from the stopper 223. The upper end surface of the resin-made protrusion 215 is provided with one IC tag 10A which is associated with the closed state of the circuit terminals 400 and 600 of the control device. That is, in the present embodiment, the upper end surface of the protrusion 215 is the IC tag 10A. Mounting surface. In addition, the IC tag 10A is used to detect whether the switch unit is in the closed state of the circuit terminal of the control device, and is also in the pressed state, so that the mounting surface of the protrusion 215 can be set in parallel as long as the IC tag 10A can be placed in parallel. The IC tag 10A can be exposed.

Further, the movable body 230 is fitted into the guide portion 213 of the base 210 from the lateral direction (the front view in FIG. 9(A), the left side view in FIG. 9(B) is the left side), and can be guided along the guide. The portion 213 moves up and down.

Further, a pair of circuit terminals 216 and 218 are provided in the base 210. The circuit terminals 216 and 218 are fixed to the mounting substrate portion 211 of the base 210 via the bolts 217 and 219, and are electrically connected to the circuit terminals 400 and 600. The pair of circuit terminals 216 and 218 are electrically switched by the short-circuiting plate 234 of the movable body. The back plate portion 212 has a concavo-convex portion that engages with a back plate portion of the adjacent switch unit. 221 is a hole through which a bolt (not shown) is passed, and the bolt is used to fix a plurality of switcher units 200 to be integrated as one switch unit group. 222 is a seat portion provided on the mounting substrate portion 211. The pair of circuit terminals 400, 600 are electrically switched by the short circuit plate 234. Further, the protrusion 223 protruding in the lateral direction of the extension portion 220 extending upward from the back plate portion 212 prevents the movable body 230 from functioning as a stopper in the downward direction of the base body 210, and is adjacent to the back of the adjacent switch unit. The holes provided on the back of the plate are engaged and have the function of positioning. Further, each of the IC tag 10 and the protrusion 215 holding the same are integrally formed, for example, from the protrusion 223 of the base 210. As a result, the movable body 230 is disposed around the protruding portion 215 of the base 210 so as to surround the protruding portion 215, and there is a space for moving up and down.

On the other hand, as shown in FIG. 10, the movable body 230 is provided with a single IC tag 10B in the concave portion 232 on the side surface of the resin body 235, which is associated with the open state of the circuit terminals 400 and 600 of the control device. The stopper 223 of the base 210 is inserted into the groove 233 on the front surface of the movable body 230, and the upper and lower limits of the movable body 230 are determined by the stopper 223. That is, in the present embodiment, the concave portion on the side surface of the movable body 230 is the mounting surface of the IC tag 10B. In addition, the IC tag 10B is used to detect whether the switch unit is in the open state of the circuit terminal of the control device, and is also in the disassembled state. Therefore, as long as the mounting surface can be disposed in parallel with the IC tag 10B, it can be exposed only when disassembled. . The depth of the concave portion can be relatively shallow. Depending on the thickness of the IC tag 10B, the concave portion can be omitted and the side surface of the movable body 230 itself can be regarded as a mounting surface.

11 to 12 further disclose the relationship between the base 210 and the movable body 230, and the respective circuit terminals of the control device are closed and opened.

In the present embodiment, similarly, the detecting adapter 155 includes a radiation antenna unit 151 and a detecting unit 152, and a transmitting unit 154 that connects them. The detecting unit 152 has a loop antenna. The transmission unit has a parallel two-wire transmission line formed of a hard conductor, and the transmission line is connected to the loop antenna of the detection unit to be connected. The radiation antenna portion 151 is covered by a strong dielectric body, and is detachably attached or detached by a single operation, such as a devil's felt or the like, to attach a connection surface of the antenna portion connected to the reader/writer device. 192. When the loop antenna surface of the detecting portion 152 is parallel to the IC tag, a strong electromagnetic coupling relationship is established.

Figure 11 (a) corresponds to the closed state of the circuit terminal of the control device, switching The movable body 230 of the unit is located at the lowest position with respect to the base 210, and the pair of circuit terminals 400, 600 are electrically closed by the short-circuiting plate 234. At this time, as shown in FIG. 11(b), the operator sets the position of the detecting adapter 155 while holding the reader/writer device 19, so that one IC tag 10A to be detected and the detection match are provided. The loop coil of the detecting portion 152 of the connector is such that the loop antenna surface of the detecting portion 152 faces the toroidal loop surface of the IC tag 10A in parallel and electromagnetically couples the two. Since the transmission unit 154 has a structure having high rigidity, the operator can select the target IC tag 10A and perform a one-to-one instruction operation without shaking. In this way, only the IC tag to be detected is selected, and the portable type detecting adapter is electromagnetically coupled with the reader/writer 19 to perform 1-to-1 communication. The distance between the adjacent IC tags 10 is set to a predetermined size, and the magnetic field lines Φ1 excited between the loop antenna of the detecting portion 152 of the adapter and the IC tag 10 are separated from the detecting portion 152 by electromagnetics. Since the square of the square is inversely proportional to the cube, the operator becomes weak and weak, so that the operator can completely eliminate the danger of communicating with the IC tag other than the IC tag indicated by the detecting unit 152. Further, the rigid transmission portion 154 ensures a sufficient length between the radiation antenna 151 and the loop antenna of the detection portion 152, so that erroneous detection does not occur. Moreover, the small IC tag 10 is made to be so sensitive that it cannot be directly detected, thereby eliminating the risk of false detection.

Next, FIG. 11(c) discloses an example of detection by the pen type reader/writer 19. The operator holds the pen type reader/writer 19, and the IC tag 10A to be detected and the detecting portion 152 of the reader/writer 19 tip are used as antenna faces and IC tags of the small antenna. 10A The toroidal toroids are in parallel or substantially parallel to each other to hold the reader/writer 19 and to electromagnetically couple the two. In this way, the operator can eliminate the danger of communicating with the IC tag other than the IC tag indicated by the pen type reader/writer 19.

Further, Fig. 12 corresponds to a case where the circuit terminal of the control device is in a completely open state, the movable body 230 of the switch unit is located at the uppermost position with respect to the base 210, and the pair of circuit terminals 400, 600 are electrically disconnected away from the short-circuiting plate 234. status.

As shown in Fig. 12 (a), the operator sets the position of the detecting adapter 155 while holding the reader/writer device 19 to detect the IC tag 10B to be detected and the detecting adapter. The loop coil of the portion 152 is such that the loop antenna surface of the detecting portion 152 faces the loop coil surface of the IC tag 10B in parallel and electromagnetically couples the two. Since the transmission unit 154 has a structure having high rigidity, the operator can select the target IC tag 10B and perform a one-to-one instruction operation without shaking. In this way, only the IC tag to be detected is selected, and the portable type detecting adapter is electromagnetically coupled with the reader/writer 19 to perform 1-to-1 communication. The distance between the adjacent IC tags 10 is set to a predetermined size, and the magnetic field lines Φ1 excited between the loop antenna of the detecting portion 152 of the adapter and the IC tag 10 are separated from the detecting portion 152 by electromagnetics. Since the square of the square is inversely proportional to the cube, the operator becomes weak and weak, so that the operator can completely eliminate the danger of communicating with the IC tag other than the IC tag indicated by the detecting unit 152.

In addition, the rigid transmission portion 154 is attached to the radiation antenna 151 and Since the loop antennas of the detecting unit 152 are sufficiently long in length, no erroneous detection occurs. Moreover, the small IC tag 10 is made to be so sensitive that it cannot be directly detected, thereby eliminating the risk of false detection.

In this embodiment, as described above, the positions of the plurality of IC tags that are mostly disposed in a narrow space are not erroneously detected; by adopting such a configuration, the position of each switch unit, or even the operation state is correct. Information can be identified in a non-contact manner by electromagnetic waves. For example, the size of one switch unit 200 is about 4.5 cm in width (X-axis), about 5.5 cm in height (Z-axis), and about 1.5 cm in depth (Y-axis), and the body 235 of the movable body 230. The height (Z axis) is about 3 cm. These switches are arranged in a plurality of Y-axis directions and are adjacent to each other at the same height. For example, in the case where the switch unit 200 group is constituted by 10 switch units, the depth thereof is about 15 cm. For example, two IC tags are housed in one switch unit, and the height is set to be approximately 3 cm.

According to the present embodiment, in one switch unit, the loop coils of the pair of IC tags 10 (10A, 10B) are several times larger than the diameter of the coil. For example, if the outer diameter of the detecting portion 152 is 5 mm of the outer diameter of the toroidal coil 102 of the IC tag, if the distance is 10 mm, the influence of electromagnetic induction is square to cubic with respect to the ring phase. In inverse proportion, it will be reduced to 1/100 to 1/1000. That is, in an independent relationship that can be ignored from each other, even if the height direction (Z direction) interval of each IC tag 10 is narrow as described above, even if the IC tag 10 of the switch unit adjacent to the position is in the lateral direction (Y direction) The interval is narrow and no false detection will occur.

Further, as shown in FIG. 12(c), in the case where the pen type reader/writer 19 is used, similarly, the operator holds the pen type reader/writer 19 while being to be detected. One IC tag 10B and the reader/writer 19 hold the reader/writer in such a manner that the antenna face of the small antenna and the toroidal coil face of the IC tag 10B face parallel or substantially parallel to each other. 19, and make the two electromagnetically coupled. In this way, the operator can eliminate the danger of communicating with the IC tag other than the IC tag indicated by the pen type reader/writer 19.

As described above, according to the present embodiment, it is possible to provide a method of communicating with an IC tag instructed and selected by the detecting portion of the detecting adapter, without inadvertently electromagnetically coupling with other IC tags, and surely performing one pair. 1 Communication, by detecting the IC tag, to know the state of the installed device or appliance in a non-contact manner.

Further, the annular inner antenna annulus of the IC tag to be detected is disposed in parallel with respect to the mounting surface, so that the protruding portion of the protruding mounting surface is reduced, and smooth mounting can be provided.

[Example 4]

Next, a fourth embodiment of the present invention will be described with reference to Figs. 13A to 14 and applied to an operation state detecting device of a control device having a disconnect switch group. This embodiment is, for example, related to an operation state detecting device of a control machine employed in a circuit breaker system group of a high voltage machine. Fig. 13A is a perspective view of the circuit breaker system of the present embodiment, and Fig. 13B is a cross-sectional view taken along line A-A' of Fig. 13A.

One set of switch units is constituted by one socket 310 and one plug 330, which corresponds to the switch unit 200 of the third embodiment. As in the third embodiment, the complex array switch unit is arranged in a row and at the same height in a direction perpendicular to the moving direction of the plug 330 (the Z-axis direction in the drawing) (the Y-axis direction in the drawing) to constitute a circuit breaker system. a circuit breaker group; the circuit terminals of the control devices of the switch units are configured to switch between the relay circuit and the control circuit, and the relay circuit controls the main circuit of each specific controlled machine of the switch system (1) ~n) High voltage power circuit breakers, etc. The plug 330 is provided with a first IC tag 10A, and the socket 310 is provided with a second IC tag 10B for integration, so as to be used in the socket 310 to detect a plurality of operating states of the control machine, that is, For example, the controller or the relay to which the circuit terminals 400 and 600 are connected is in an electrically connected state or in an open state. The positional relationship of the plug 330 with respect to the socket 310 is configured to be relatively changeable. Each IC tag is arranged such that the toroidal surface of the antenna is parallel to the mounting surface. The operation state of each switch unit can be read by the reader/writer 19 through the same detection adapter 155 shown in the third embodiment. That is, the state is detected by the combination of the detection of the first IC tag 10A and the second IC tag 10B so as to correspond to the respective operational states of the plug 330, that is, the control is to use the main circuit function of the controlled machine (ON) Or invalidate it (OFF); for example, pulling the plug 330 to cut off the circuit terminals 400 and 600, that is, the main circuit function is inactive (OFF) state, or pressing the plug 330 into the circuit The state in which the terminals 400 and 600 are wired; in other words, the states corresponding to the active (ON) state and the inactive (OFF) state of the main circuit. State In the detection, the first IC tag 10A and the second IC tag 10B are sequentially detected by the reader/writer 19 through the detecting adapter 155, or simultaneously detected, thereby identifying each state.

The socket 310 has a resin-made mounting substrate portion 311, holes 311, 312 for inserting the electrodes 331, 332 of the plug 330, and bolt holes 313 for locking the bolts 333 of the plug 330. A first IC tag 10A is attached to the side of each plug 330, which is associated with the unique information of the plug. On the other hand, on the inner side surface of the end portion 314 of the socket 310, a second IC tag 10B is fixed, which is associated with the unique information of the socket and faces the first IC tag 10A.

Fig. 14 illustrates a method of detecting the active (ON) state and the inactive (OFF) state of the main circuit using the detection adapter 155.

In the present embodiment, similarly, the detecting adapter 155 includes a radiation antenna unit 151 and a detecting unit 152, and a transmitting unit 154 that connects them. The detecting unit 152 has a loop antenna. The transmission unit has a parallel two-wire transmission line formed of a hard conductor, and the transmission line is connected to the loop antenna of the detection unit. The radiation antenna portion 151 is covered by a strong dielectric body, and is detachably attached or detached by a single operation, such as a devil's felt or the like, to attach a connection surface of the antenna portion connected to the reader/writer device. 192. When the loop antenna surface of the detecting portion 152 is parallel to the IC tag, a strong electromagnetic coupling relationship is established.

In Fig. 14(a), the plug 330 is coupled to the socket 310 to be in an active (ON) state for the main circuit. At this time, the loop antenna of the detecting unit 152 corresponds to the two IC labels of the first IC tag 10A and the second IC tag 10B. sign.

That is, the IC tag 10A is assembled at a specific portion of the plug 330, and when the plug is inserted into the socket 310, the toroidal coil faces of the two separately assembled IC tags 10A, 10B face in parallel, and the detecting portion of the detecting adapter 155 is used. A loop antenna of 152 detects the insertion state of the plug. In this manner, the detecting portion 152 of the detecting adapter 155 is placed on the coil faces of the parallel arrangement of the two IC tags 10A, 10B, and the loop antenna coil faces of the detecting portion 152 are parallel, and thus, as shown in Fig. 14 (b) As shown, electromagnetic coupling of three coil faces is generated, and the test adapter 155 can simultaneously communicate with the two IC tags 10A, 10B.
