[0002]

2. Description of the Related Art There are many cases in which guards are patrolling to guard buildings and company facilities. The guards patrol the specified patrol points at regular intervals, etc.
Check and check if there are any abnormalities. The person who manages the guard is
It is necessary to confirm when the guards go around the patrol points and whether the patrols are performed normally. In the conventional management system, it is determined whether or not the patrol is normally performed based on the patrol report submitted by the guard after the patrol. In some large-scale companies, a centralized management system has been introduced.In this case, the door key at the patrol point is linked to the centralized management system, and the security guard unlocks and enters the room. The centralized management system is notified of this and manages the successful patrol. Recently, a system has been studied in which a sticker or the like representing the location data in a bar code is attached to each patrol location, and the guards patrol with a bar code reader and check by reading the bar code. There is. In addition, JP-A-9-147276
In the bulletin, at each patrol place, a display device that displays the time, place, etc. data in a bar code is installed, and the guards patrol with a bar code reader to read the data of each display device. The system to check is described.

[0003]

However, in the method using the patrol report submitted by the guard, there is a problem that the guard does not understand even if he / she writes a false report in the patrol report. In the method of linking, the centralized management system is expensive and can be introduced in a large company, but it cannot be introduced in a small company. In addition, in the method using the bar code seal, the bar code is vulnerable to dirt and cannot be read when the surface is dirtied by dust or the like. Also, the sticker may peel off, making it difficult to use in places with poor environment such as outdoors. Moreover, the barcode can be duplicated by copying, etc., and the barcode at the patrol point can be duplicated,
There was a problem in that it was possible to make an illegal move by scanning the duplicated barcode at an office or the like instead of making a patrol point and deciding to make a patrol. In addition, JP-A-9-14727
The method according to 6 has an advantage over the method according to the barcode sticking method in that the content of the barcode is a random number, but there is an advantage that fraud can be prevented. However, since the place and time are displayed on the display device displaying the barcode, However, there is a problem that the control device is required.

BEST MODE FOR CARRYING OUT THE INVENTION Regarding one embodiment of the present invention,
This will be described with reference to FIGS. 1, 2, 3, 4, and 5. 1 is a system configuration diagram of a security guard management system according to an embodiment of the present invention, FIG. 2 is an internal configuration diagram of a tag reader, FIG. 3 is an operation flow diagram of a security guard, and FIG. 4 is data in a memory inside the tag reader. FIG. 5 is an explanatory diagram of a management screen on the headquarters server. As shown in FIG. 1, a non-contact IC is attached to one or a plurality of patrol points patroled by a security guard.
The tag 6 is set by pasting or embedding. The non-contact IC tag is a tag having an IC chip built therein, and can be read in a non-contact manner using a radio wave signal by a tag reader which is a non-contact type reader. Each non-contact IC tag has a unique tag number stored therein, and this tag number is read by the tag reader. The tag number of the tag installed at each patrol point should be clarified in advance.

As shown in FIG. 2, the tag reader is CP
U11 and antenna 1 for reading non-contact IC tags
2, a tag information reading unit 13 that processes a signal received by the antenna, an internal clock 14, a memory 15 that stores the read signal and time data, and an infrared communication unit 16 for communicating with the management personal computer 3. Operation key 1
7 and 7.

The non-contact IC tag is generally an RFID tag (Radio frequency Identity).
What is referred to as an “application TAG” can be used. There are two types of non-contact IC tags of this type, which have a battery as a power supply device inside, and ones which operate by electric power transmitted by electromagnetic waves from a tag reader.
The latter is commonly used from the viewpoint of maintainability and downsizing.

FIG. 9 is a circuit block diagram of a non-contact IC tag composed of an RFID tag. The non-contact IC tag 40 is C
A PU 41, a transmission / reception circuit 42, a rewritable non-volatile memory 43, a power storage capacitor 44, and an antenna coil 45 are provided, and the parts other than the antenna coil 45 are contained in an IC chip 46 indicated by a chain double-dashed line.

A control sequence is programmed in the tag reader in advance, and when a read command is issued, an electromagnetic wave for power transmission is first output from the antenna 12, and the electromagnetic wave is received by the antenna coil 45 of the non-contact IC tag 40. The data is stored in the capacitor 44 via the transmission / reception circuit 42, and the CPU 41 and the like are driven. Next, an electromagnetic wave for reading is output from the antenna 12, which causes C
The PU 41 transmits the unique code stored in the memory 43 from the antenna coil 45 to the antenna 12 via the transmission / reception circuit 42. As a result, the tag reader is contactless I
The unique code of the C tag can be read. Note that this series of operations is completed almost instantly.

FIG. 10A is a schematic view of a non-contact IC tag 40 having a disk-shaped antenna coil. The antenna coil 45 is composed of a circular air-core coil, and both ends of its winding are connected to the transmitting / receiving circuit 42 of the IC chip 46.

FIG. 10B is a diagram for explaining the relationship between the antenna coil 45 and electromagnetic waves. Generally, an electromagnetic wave can be represented by an electric field and a magnetic field propagating in an alternating manner with a phase difference of 90 degrees, and the magnetic field H and the antenna coil 45 are linked to each other to transmit / receive using a current (high frequency current) flowing in the coil. Is done. The magnetic flux used for transmission and reception draws a loop in the direction of penetrating the inside of the circular air-core coil.

FIG. 11 shows a cylindrical antenna coil 45.
It is a schematic diagram of a non-contact IC tag 40 having. The antenna coil 45 has a rod-shaped core 47 made of a magnetic material and a conducting wire 48 wound around the rod-shaped core 47, and an IC chip 46 is attached to a part thereof. The magnetic flux used for transmission / reception of the cylindrical antenna coil 45 draws a loop that exits from one core end and enters the other end as shown in the drawing, and this loop switches alternately in forward and reverse directions according to the frequency.

As a transmission / reception (communication) method of the non-contact IC tag 40, for example, a frequency shift keying method (FSK: Frequency) using two waves of 125 kHz and 117 kHz is used.
Cyshift Keying) and an amplitude shift keying method (ASK: Amplitude Sh) that uses only one wave.
There are two types (ift Keying), but non-contact IC
It is desirable to use the ASK method that can relatively stably transmit and receive with the tag reader even if a conductive member such as a metal is present near the tag 40.

During the patrol, the security guard travels around the patrol points with a tag reader. The operation flow of the security guard at this time is shown in FIG. When the guard arrives at the first patrol point, the tag reader reads the contactless tag installed at the patrol point. Next, using the operation keys of the tag reader, the security guard number defined for each security guard and the patrol result indicating whether or not there is an abnormality are input to the tag reader. At this time, the memory 1 of the tag reader
5, as shown in FIG. 4, the read tag number, the read time acquired from the internal clock, the input guard number,
The patrol results are recorded. If there is a next patrol point, head to the next patrol point, and after arriving at the patrol point, read tag information in the same way, enter the guard number,
Repeat the patrol result input. At the end of the patrol, the security guard returns to the office or the like and transfers the memory contents of the tag reader to the management personal computer 3 using the infrared communication unit 16 by operating the tag reader operation key. The memory contents of the tag reader are transferred from the management personal computer 3 to the headquarter server 1 via the public line 2. The headquarters server 1 displays a management screen as shown in FIG. 5 according to the transferred data. The name of the traveling point on this screen is registered in advance in combination with the tag number, and it is determined from the tag number in the transferred data. The tag number is the tag number in the data, the patrol time is the reading time in the data, and the patrol result is the reading result in the data. The security guard name is registered in advance as a combination of security guard numbers, and is discriminated from the security guard number in the data. The administrator can confirm whether or not the guards have normally made a patrol from this management screen. Next, an embodiment of the present invention will be described with reference to FIGS. 6, 7 and 8. FIG. 6 is a system configuration diagram of a security guard management system according to one embodiment of the present invention (when connected to a mobile phone), and FIG. 7 is an internal configuration diagram of a tag reader (when connected to a mobile phone).
FIG. 8 is an operation flow diagram of the security guard (in the case of mobile phone connection). As shown in FIG. 6, the non-contact IC tag 6 is attached or embedded at one or a plurality of patrol points on which the guard patrols as in the case of the previous example. The non-contact IC tag is the same as the preceding example. As shown in FIG. 7, in addition to the tag reader shown in FIG.
Has been added. At the time of patrol, the guard takes a tag reader and patrols the patrol points. The operation flow of the security guard at this time is shown in FIG. When the guard arrives at the first patrol point, the tag reader reads the contactless tag installed at the patrol point. Next, using the operation keys of the tag reader, the security guard number defined for each security guard and the patrol result indicating whether or not there is an abnormality are input to the tag reader. At this time, as shown in FIG. 4, the read tag number, the read time acquired from the internal clock, the input guard number, and the patrol result are recorded in the memory 35 of the tag reader. This information is transferred in real time to the headquarters server using the connected mobile phone 23. If there is a next patrol point, head to the next patrol point, and after arriving at the patrol point, similarly read tag information, enter guard number, and enter patrol result. At this time, similarly, the information is transferred to the headquarters server in real time using the mobile phone. The headquarters server 21 displays a management screen similar to that shown in FIG. 5 according to the transferred data. The administrator can confirm in real time that the guards have made a proper patrol on this management screen. If a management PC 3 is prepared in the same way as in FIG. 1, even if the mobile phone cannot be used due to bad radio wave conditions, the memory contents of the tag reader are managed by the management PC by the management server as in the previous example. Can be transferred to.

In general, a non-contact IC tag is difficult to read when it is attached or embedded on the surface of a conductive member such as metal. That is, when the magnetic flux used for transmission / reception interlinks with the conductive member, an eddy current is generated in the conductive member, whereby a magnetic flux in the direction of canceling the transmission / reception magnetic flux is generated. As a result, the magnetic flux available for transmission and reception is significantly reduced, making communication difficult. However, the present inventors have found that by adopting a special configuration or system, it is possible to perform transmission / reception relatively easily with high communication sensitivity and certainty.

Therefore, a non-contact IC at the traveling point
When the object to which the tag is attached is a metal such as a safe, or to prevent damage from the outside, the non-contact IC tag is placed inside a protective body or container made of a conductive material such as metal with high mechanical strength. In the case of housing, it is desirable to use the non-contact IC tag having such a configuration.

FIG. 12 is a sectional view showing an example in which the non-contact IC tag 40 is housed in a protective body made of a metal material. The non-contact IC tag 40 has a disk-shaped antenna coil 45, and is molded in a resin container 49 together with an IC chip 46 fixed to a part thereof to form a thin disk shape as a whole. The container 49 is further housed in a protective body 50 made of a metal material such as aluminum. The protector 50 is composed of an upper plate 51, a lower plate 52, and a side plate 53 interposed therebetween, and the upper plate 51 and the lower plate 52 are fixed to the side plate 53 with an adhesive or the like. The adhesive layer forms a gap around the metal boundary portion, and the gap forms the magnetic flux leakage path 54.

[0033] On the other hand, one side of the disk-shaped antenna coil 45
From the magnetic flux leakage path 54 to the first sheet-shaped magnetic body 5
5 is extended and the magnetic flux from the opposite side to the opposite side from the above
The second sheet-shaped magnetic body 56 extends toward the leakage path 54.
To be done. Then, the first sheet-shaped magnetic body 55 and the second sheet-shaped magnetic body 55
The magnetic material 56 is continuous with the antenna coil 45.
Form a unique magnetic flux path.

Each of the first sheet-shaped magnetic body 55 and the second sheet-shaped magnetic body 56 is formed by cutting a sheet-shaped magnetic body having a thickness of about 10 μm to 50 μm into a rectangular shape. The first sheet-shaped magnetic body 55 is the antenna coil 4
Along the upper surface of 5, the central part is extended from the left side to the outer side in the right direction, and a part thereof is fixed to the upper surface side of the antenna coil 45 by adhesion or the like. In addition, the second sheet-shaped magnetic body 5
Reference numeral 6 extends along the lower surface of the antenna coil 45 from the center slightly right side to the outside in the left direction, and a part thereof is fixed to the lower surface side of the antenna coil 2 by adhesion or the like.

[0035] As a result, the central part of the antenna coil 2
The first sheet-shaped magnetic body 55 and the second sheet-shaped magnet located
The ends of the body 56 are partially overlapped with each other (Oh
I am wrapping). And at least part of the magnetic flux H
In this case, the first
The sheet-like magnetic body 11 and the second sheet-like magnetic body 12
As each shows, it is shown by the dotted line through the antenna coil 45.
Form a flat and enlarged magnetic flux path (flux loop)
It

Both sides of the antenna coil 45 are provided with a container 51.
Since the first sheet-shaped magnetic body 55 and the second sheet-shaped magnetic body 56 are accurately arranged via the resin layer, the first sheet-shaped magnetic body 55 and the second sheet-shaped magnetic body 56 are directly contacted with each other without the resin layer. There is not much difference in operation from the case of making it. Although the amount of clearance depends on the desired amount of magnetic flux leakage, it is several hundred μm to several m for normal communication.
It is sufficient to set it in the range of about m.

The first sheet-shaped magnetic body 55 and the second sheet-shaped magnetic body 56 have the function of suppressing the attenuation of the magnetic flux used for transmission and reception and the function of enhancing the directivity of communication. The sheet with higher non-permeability becomes larger. Therefore, the first sheet-shaped magnetic body 55 and the second sheet-shaped magnetic body 5
6 is preferably a magnetic body having a relative magnetic permeability of at least 10,000 or more. As a magnetic material having such a high relative magnetic permeability, a sheet-shaped amorphous magnetic material can be mentioned.

Generally, the relative magnetic permeability of the amorphous magnetic material is in the range of tens of thousands to several millions, and the relative magnetic permeability is extremely high. For example, there is an Fe-Ni-Mo-BS system sheet-like amorphous magnetic material having a relative magnetic permeability of 800,000, which is commercially available from Allied Chemical Company of the United States, and a sheet having a similar composition and a higher relative magnetic permeability. Amorphous magnetic materials are commercially available from Hitachi Metals, Ltd. and any of them can be used in the present invention.

The protector 50 as shown in FIG. 12 is a so-called IC.
It has the same form as a card and can be fixed to the surface of an object such as a safe with an adhesive or a screw. Therefore, since there is substantially no portion that protrudes from the surface of the object, aesthetic problems do not occur, and there is no risk of damage due to mechanical shock from the outside.

Next, the transmitting / receiving operation of the non-contact IC tag 40 of FIG. 12 will be described. When an electromagnetic wave for calling is output from the tag reader, its magnetic flux H passes through the magnetic flux leakage path 54 and passes through the first sheet-shaped magnetic body 55-antenna coil 45-second sheet-shaped magnetic body 56 as a magnetic flux loop. Received by. And the CP embedded in the IC chip 46
U reads the unique code stored in the memory and transmits it from the antenna coil 45 to the outside. A similar magnetic flux loop H is formed in this transmission as well.

As the first sheet-shaped magnetic body 55 and the second sheet-shaped magnetic body 56, sheet-shaped amorphous magnetic bodies having a relative magnetic permeability of 800,000 manufactured by Allied Chemicals were used. Magnetic flux leakage path 5
4, a void having a thickness of several hundreds of μm was provided along the entire circumference. The protective container 50 had a horizontal length of 85 mm, a vertical length of 55 mm, and a thickness of 1 mm. The communication distance of a normal tag reader was about 300 mm. on the other hand,
First sheet-shaped magnetic body 55 and second sheet-shaped magnetic body 56
Without the provision, practical communication was not possible.

FIG. 13 shows an example in which a non-contact IC tag having a cylindrical antenna coil is housed in a container as a protector. The container 60 is a main body 61 having an opening at the top.
And a lid 62 that covers the opening of the lid, and a magnetic flux leakage path 63 is formed at least at the boundary between the main body 61 and the lid 62. The main body 61 has an accommodation space inside, and the non-contact IC tag 40 having a cylindrical antenna coil and an IC chip as shown in FIG. 11 is accommodated in the accommodation space. The non-contact IC tag 40 is stably held by a filling member 64 such as an adhesive filled around the non-contact IC tag 40, and the axial direction of the core thereof faces the magnetic flux leakage path 63.

The upper lid 62 is detachably fixed to the main body 61 by a plurality of screws 65, and a magnetic flux leakage path 63 is formed at the peripheral portion of the boundary portion. The gap of the magnetic flux leakage path 63 is set in the same range as in the case of FIG. 12, but its value is, for example, between the main body 61 and the upper lid 62, a non-conductive or non-magnetic material such as a fiber material or a resin material. It can be adjusted by interposing a packing sheet made from the above and selecting the thickness thereof.

In the case of a non-contact IC tag having such a cylindrical antenna coil, the magnetic flux used for transmission and reception passes from the core tip portion through the magnetic flux leakage path 63 and leaks in a loop as shown in the drawing. It is possible to send and receive with high communication sensitivity as it is by using.

FIG. 14 shows an example in which a non-contact IC tag having a cylindrical antenna coil is installed on a fixed installation member at a traveling point. In this case, the protector in the present invention, an installation groove portion provided in the fixed installation member,
It is formed by a metal lid that covers the installation groove and is fixed to the installation member. The installation member may be either metallic or non-metallic.

The non-contact IC tag 40 is installed with the cores parallel to each other. And the periphery thereof is a filling member 7 such as an adhesive.
It is stabilized at 4, and is further covered with a lid 75.
The lid 75 is fixed to the installation member 70 with a plurality of screws 76,
A magnetic flux leakage path 77 is formed at the boundary between the lid 75 and the installation member 70. The method of forming the magnetic flux leakage path 77 and adjusting the gap thereof is the same as in the case of FIG.

FIG. 15 shows another example in which a non-contact IC tag having a cylindrical antenna coil is installed on a fixed installation member at a traveling point. In this example, the installation member 70
The installation groove 72 having a step is formed on the bottom surface, the non-contact IC tag 40 is installed on the bottom surface 73, and the lid 75 is dropped in the step. This example is effective when it is not desired to have a protruding portion on the surface of the installation member 70. Since the other structure is the same as that of FIG. 14, its description is omitted.

When a communication experiment was conducted with the tag reader in the examples of FIGS. 13 to 15, it was possible to perform transmission / reception with good communication sensitivity as in the example of FIG.
