Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a monitoring device for preventing theft of objects such as works of art and jewelry.

[Conventional technology and its problems]

2. Description of the Related Art Conventionally, as a system for preventing theft of displayed works of art, jewelry, etc., there is a system in which infrared sensors, ultrasonic sensors, etc. are placed around the objects, and the movement of the objects is monitored by detection by the sensors.

However, although the above system can monitor whether the item is in a designated location, it cannot detect if the item is somehow replaced with another item (for example, a counterfeit item). , which has the disadvantage of lacking credibility.

On the other hand, there is a method of placing television cameras at the display area of goods and monitoring the theft of individual goods by watching the TV screen displayed, but this method requires constant monitoring of the screen. The disadvantage is that it places an extremely heavy burden on people, and since it relies on human supervision, it is difficult to obtain complete reliability.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a monitoring device that can independently identify and monitor each article and has high reliability and accuracy.

[Means to solve the problem]

In order to solve the above problems, the present invention attaches an identification member having information that distinguishes the item from other items to items arranged at a predetermined position, and reads the information on the identification member while facing the item. A reading means is provided, and a control device is connected to the reading means, which compares the read information with previously stored information and outputs a signal to a display device if the results do not match.

Note that in the above structure, the identification member can be a storage element that can read information by electromagnetic induction.

[Effect]

In the above structure, the control device compares the information read by the reading means with the information stored in advance at all times or at predetermined intervals.

In this case, if the item is not in the specified position or the item is different from the target item, the reading information and storage information will not match, so a signal will be output from the control device to the display device to notify you of this fact. be able to.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

FIG. 1 is a block diagram showing the basic structure for monitoring one article.

In the figure, 1 is a displayed article such as a work of art, 2 is a wall facing the article 1, and an identification member 3 containing information unique to the article 1 is attached to the article 1. 2 is provided with a reading means 4 that faces the identification member 3 and reads information on the identification member 3.

Further, a control section W5 consisting of a microcomputer or the like is connected to the reading means 4, and a display device 6 serving as a means for transmitting information to the outside is connected to this control device 5.

Information for identifying goods may include a group of numbers that are a combination of multiple digits (e.g. 000001') or a group of symbols that are a combination of multiple alphabetic symbols (&l1-) (e.g. AB
CDEF), or a combination of the above group of numbers and symbols with a secret code only for the user can be used.

On the other hand, as shown in FIG. 2, the identification member 3 includes an EFRO
It is possible to use a memory element 3' that includes a memory 3a such as M or the like, an electromagnetic coil 3b that transmits information in the memory as radio waves, and transmits information in a non-contact manner, a barcode sheet, or the like.

In this case, the non-contact storage element 3', which can exchange information using magnetism or radio waves, does not have a mechanical contact structure, so it is highly durable, has excellent waterproof and dustproof properties, and is suitable for art. It has excellent characteristics when used as an identification member for monitoring products, etc. In addition, recent contactless memories mentioned above include
There are devices that can read from a distance of up to 100 cII + and have a reading speed of less than 100 m9 seconds, which has sufficient reception ability and responsiveness for use in monitoring goods. It has reached this point.

In addition, as the reading means 4, when a non-contact type storage element 3' is used as the identification member, as shown in FIG. 2, an antenna 7 that converts information stored in the storage element into radio waves and reads it; A system comprising a controller 8 that identifies the radio waves read by the antenna 7 and sends the information signals to the control device 5 is used. In addition, the controller 8 has
In addition to the radio wave processing section 8a, an interface 8b that can be connected to external equipment is provided.

On the other hand, when a barcode sheet is used as the identification member 3, a reading device for optically reading the barcode is used as the reading means 4.

On the other hand, the control device 5 includes a memory section 9 and a comparison control section 10.
The same content as the identification information stored in the identification member 3 is registered in advance in the memory section 9 in association with each identification member 3.

Further, when the information signal is input from the reading means 4, the comparison control section 10 extracts registered information corresponding to the manually inputted information from the memory section S, compares this registered information with the input information, and compares the registered information with the input information. The configuration is such that a signal is output to the display device 6 when the display device 6 is connected. In addition, the case of inconsistency mentioned here is
In addition to the case where there is a difference in a part of the information, it is also determined that there is a mismatch with the registered information when the article 1 is not in a predetermined position and there is no read information. That is, only when the contents of the read information and the registered information completely match, it is determined that the information matches, and no signal is output to the display device 6.

The above information comparison of the control device 5 is carried out at all times or at predetermined intervals.

The display device 6 is used to notify related parties such as security guards when the control device 5 determines that there is a discrepancy in information, and includes an alarm, a display that displays the abnormal item and its location,
Or a combination of both can be used.

In the above monitoring structure, if the article 1 is moved from a predetermined display position without prior notice, there will be a mismatch between the information output from the reading means 4 and the registered information stored in the control device 5. Stakeholders will be informed.

Furthermore, since the information on the identification member 3 and the registered information correspond one-to-one, if an item is replaced with a fake item, it can be detected at that point.

FIG. 3 shows an embodiment in which the monitoring device of the present invention is used to monitor a large number of articles.

In the figure, 11 is a memory element attached to each article, 1
Reference numeral 2 denotes a reading antenna provided opposite to each memory element 11, and 13 a controller for identifying the signal of each reading antenna 12. A corresponding pair of reading antenna 12 and controller 13 constitute a reading means.

Further, a plurality of sets consisting of the memory element 11, antenna 12, and controller 13 are assembled to form one loop, and each loop is connected to a connecting device 1.
It is connected to the host computer 15 via 4. Further, a display device 16 is connected to this host computer 15.

In the monitoring structure in which the monitoring network is configured as described above, each storage element 11 is written with a unique identification code that is different from other storage elements, and the host computer 15
A code corresponding to the identification code is stored in the memory device, and the antenna 12 continues to read information from each memory element 11, and the computer 15 identifies which controller 13 has read the information and detects any discrepancies. confirm. This makes it possible to centrally manage article monitoring for multiple reading locations at the same time.

In addition, when the display position of the article is changed in the above structure, the content of the registered information is changed in the host computer 15 in accordance with the change in the display position.

〔Effect of the invention〕

As described above, according to the present invention, unique information is added to articles using an identification member, and the articles are monitored based on the information, so that each article itself can be identified and monitored. Therefore, it is possible to reliably monitor whether a given item is in a predetermined position, and it is also possible to immediately detect if it has been replaced with another item.
It is possible to perform article monitoring with extremely high reliability.

Furthermore, since there is a one-to-one correspondence between items and information, it can be used to determine whether an item is genuine or fake.
