Description

The present invention relates to a self-sounding product antitheft system with a wireless communication function, and more particularly, a wireless communication function capable of monitoring antitheft from a remote location by a method for further enhancing the antitheft function of the product. It relates to a self-sounding product anti-theft system.

In general, an alarm generation device (theft prevention device) used for theft prevention refers to a device that attaches a theft prevention tag to a relatively expensive item and sounds an alarm sound when passing an unauthorized search platform. Say. This is mainly configured to sound an alarm using an electromagnetic induction phenomenon, and the electromagnetic induction phenomenon means that if a magnetic field changes inside the solenoid (coil), a current is generated in the solenoid.

  When you try to carry out a product from a store such as a distribution store (large supermarket), a library, or a sound board, you will be forced to pass through a search table with a sensor. Even a slight change in the magnetic field generated in the magnetic field region can be detected.

For this reason, if an anti-theft tag with a magnetic field property is attached to a book or article, and it is carried out without losing the magnetic field sensing property, an electromagnetic induction phenomenon is received and received as a signal, and an alarm is sounded from the search platform. .

On the other hand, recently developed RFID technology is a technology for automatically recognizing information contents of various things using a wireless recognition technology in a ubiquitous network environment.

The RFID system basically includes a tag card, a reader, and a host computer (or application). The tag includes a radio frequency (RF) function, a memory, and an antenna or a power source, and interfaces ID / information on the tag memory using the radio frequency.

Various applications of the RFID system have been developed and commercialized according to the target to which the ID / information on the tag memory and the radio frequency interface are applied, the method of use, and the given environment.

However, since various existing anti-theft devices employ a method in which an alarm bell is sounded only in the sensing area (mainly in and out of the area) if the tag attached to the product simply passes the sensor. When removing a tag from a product, there is a big problem that it cannot cope with theft at all.

  In addition, it is not a method of recognizing the tag state and tag attachment / non-attachment status using wireless communication between the tag and the sensing device, but physical characteristics such as magnetic characteristics in the sensing region depending on the presence / absence of the tag in the sensing region of the sensor. Because it uses only a method to detect changes in characteristics, it is exposed to a risk factor that reduces the possibility that the administrator will recognize theft situation in real time when the sales floor is large or the sales floor is crowded Since the common tag is applied to all products and sales floors, it is impossible to achieve an independent or systematic security level for each sales floor. As a result, there is a drawback in that the security level for preventing goods theft at the sales floor is lowered.

  In order to provide an anti-theft function in the sales floor, a device related to the production of a self-sounding tag utilizing an existing RF type EAS main device has been proposed (see, for example, Patent Document 1 below), but only from a terminal. Since the alarm does not sound, it is very weak to the removal of the alarm sound by the non-applied person and the disabling of the terminal alarm function in the shaded area in the sales floor.

Moreover, although the function which distinguishes a multiple gate by issuing a separate LF signal is proposed (for example, refer to the following patent document 2), in this case, an alarm sounds only from a terminal.

  Furthermore, a self-sounding anti-theft system using an existing RF type EAS main device has been proposed (see, for example, Patent Document 3 below), which discloses a low power method for the main device. However, similarly, since the alarm sounds only from the terminal, there is a problem that the security strength is significantly reduced.

Furthermore, although a technique related to a self-sounding tag has been proposed (see, for example, Patent Document 4 below), similarly, since an alarm sounds only from a terminal, an alarm sound by a non-applied person in a shaded area in a sales floor There is a disadvantage that it is very weak to the removal of the terminal and the disabling of the terminal alarm function.

International Patent Application No. PCT / JP99 / 06498 Japanese Patent Laid-Open No. 04-242892 International Patent Publication No. WO2010 / 127293 JP-A-11-353562

  In order to solve the above-mentioned problems, the present invention uses the operation of LED lamps and beeps when the tag attached to the product is damaged without permission or when it is attempted to be removed from the product. In the existing system that notifies the theft of the product by sounding the alarm and reporting the sound to the management staff, there is a problem that the alarm sound of the tag is not audible when the sales floor is wide or the sales floor is crowded. In order to solve the problem that the risk of product theft increases when the sound generation circuit of the product breaks down, when the theft of the product is detected, the status is accurately communicated to the administrator in real time. The purpose is to provide an anti-theft system capable of minimizing theft of merchandise.

Another object of the present invention is to suppress the occurrence of false alarms by distinguishing alarms of other sales floors when trying to apply the same security system to many sales floors with different brands and management systems in the same space. In addition, the present invention is to provide an anti-theft system capable of reducing the management labor cost by centrally managing alarms of a large number of sales floors in a plurality of areas having the same management system.

  In order to achieve the above-described object, the present invention is provided in a product corresponding to an anti-theft object in an anti-theft system, and designated as a sensing unit that senses the presence or absence of the theft by a wire or a switch structure.

And a remote alarm receiver having a display unit that outputs a stored identification code corresponding to information to the tag unit.

  Preferably, the anti-theft system is configured such that an authorized user can easily generate an identification code to be stored in the storage unit of the tag unit and transmit the generated identification code to the first signal receiving unit. And a code signal generator for providing an identification code signal as a wireless signal to be stored in the unit.

  Further preferably, the tag unit further includes an alarm display unit for realizing lamp output or sound output.

  Further, preferably, the tag unit is arbitrarily added with an identification code when the tag is generated and stored, or is received via the code signal generator and stored in the storage unit.

Further preferably, the first receiving unit receives any one of an EM signal, an RF signal, an AM signal, and an LF signal when receiving a signal from an external signal device.

  Further preferably, the remote alarm receiver further includes a storage unit that stores an identification code included in an arbitrary tag unit, and a reception signal is generated from the tag unit corresponding to the identification code stored in the storage unit. Configured to output an alarm signal.

Further preferably, the remote alarm receiver further includes a storage unit that stores an identification code included in an arbitrary tag unit, and a reception signal is generated from the tag unit corresponding to the identification code stored in the storage unit. Configured to output an alarm signal.

Further preferably, the remote alarm receiver further includes an external device communication unit connected to the external terminal by wire or wirelessly, and provides a signal received via the external device communication unit to the external terminal.

Further, preferably, the tag unit stores the unique identification code stored in the storage unit as a fixed type identification code and a movable type identification code, respectively. The movable type identification code is further inputted by the code signal generator after the fixed type identification code has already been inputted. And each can be identified separately.

The self-sounding merchandise theft prevention system with a wireless communication function according to the present invention having the above-described configuration has a feature that merchandise theft can be monitored from a remote place. That is, the self-sounding merchandise anti-theft system with wireless communication function according to the present invention applies the communication technology between the two (terminal and remote information receiver) to a single monitoring system that relies on tag alarms to prevent theft.

A is a block diagram of the tag unit in the self-sounding merchandise anti-theft system with wireless communication function according to the present invention, and B is a detailed diagram of the storage unit of the tag unit according to the present invention. It is a block diagram which shows the example of the remote alarm receiver in the self-sound type goods antitheft system with a wireless communication function which concerns on this invention. It is a block diagram which shows the example of the remote alarm receiver with an alarm reception setting function in the self-sounding merchandise antitheft system with a wireless communication function according to the present invention. The block diagram which shows the example of the remote alarm receiver with a wired / wireless communication function with the external apparatus in the self-sounding goods antitheft system with a wireless communication function which concerns on this invention.

Hereinafter, a preferred embodiment of a self-sounding merchandise antitheft system with a wireless communication function according to the present invention will be described in detail with reference to the accompanying drawings.

A self-sounding product antitheft system with a wireless communication function according to the present invention is provided in a product corresponding to an antitheft object in the antitheft system, and includes a sensing unit that detects the presence or absence of theft by a wire or a switch structure. A detection unit including a storage unit that stores a specified identification code, a first signal reception unit that receives a radio signal to store the identification code, and a signal detected by the commodity theft detection unit; A tag unit 100 having a first signal transmission unit that transmits to the outside, a second signal reception unit that receives a signal transmitted from the first signal transmission unit provided in the tag unit, and the second signal reception unit And a remote alarm receiver 300 having a display unit for outputting a stored identification code corresponding to information to the tag unit received via the remote control unit.

The self-sounding merchandise anti-theft system with wireless communication function according to the present invention is provided in a product corresponding to an anti-theft object, and includes a wire breakage detection unit 110 that senses whether the theft is detected by a wire or a switch structure. A detection signal including a signal detected by the storage unit 130 for storing the specified identification code, the first signal receiving unit 140 for receiving a wireless signal to store the identification code, and the merchandise theft detection unit; The tag unit 100 having the first signal transmission unit 150 that transmits to the outside, and the identification code to be stored in the storage unit of the tag unit is generated and transmitted to the first signal reception unit to store the identification code A code signal generator 200 that provides an identification code signal as a radio signal, and a signal transmitted from a radio transmission unit provided in the tag unit It comprises a remote alarm receiver 300 having a display unit for outputting the stored identification code corresponding to the second signal receiving unit and the information on the tag section which is received via the second signal receiving unit.

The self-sounding tag provided in the anti-theft system according to the present invention has its own unique identification code (each unique ID), and if a signal is transmitted from each tag itself, the remote alarm receiver is removed from the tag. The main technical point of view is that a system that can receive the signal and output an alarm signal can be separately recognized through a unique identification code.

In particular, the tag can be classified by the administrator by selectively inputting individual unique identification codes, such as product types and sales floor types, and a grouping function can be added using the identification codes. This can be used to classify the signals together. That is, since each tag can be managed and detected separately, a system optimized for an individual anti-theft system for goods is realized.

  On the other hand, the anti-theft system according to the present invention can prevent an error that the tag information registered in another sales floor is recognized or displayed on the receiving device provided in the monitoring range by using the information of the identification code. Since the alarm signal can be distinguished according to the theft type of the product with the active tag, there is an advantage that the efficiency of the theft information management can be maximized.

An electronic article surveillance system (EAS) equivalent to the anti-theft tag system is a passive EAS in which a tag (for attachment to a product) has no battery, and an active EAS in which a battery is contained in the tag. It is divided into. Passive type EAS can be classified into RF type EAS, AM type EAS, and EM type EAS according to the signal generation technology. In the case of the active type EAS, an alarm is generated from the tag. Therefore, it is usually referred to as a “self-sounding anti-theft system”.

The tag unit 100 according to the present invention can input a unique identification code of each tag unit via a code signal generator 200 that provides an identification code by a non-contact wireless method. The first signal transmission unit 150 stores the generated code and sends an alarm generated from the tag to the remote receiving device. The remote alarm receiver 300 according to the present invention receives and displays an alarm signal transmitted by the tag unit 100, and informs an administrator using sound, light, or remote communication, and an alarm generation unit. 330 is provided.

FIG. 1 is a block diagram of a code signal generator in a self-sounding merchandise antitheft system with a wireless communication function according to the present invention.

The code signal generator 200 according to the present invention corresponds to a device that generates an arbitrary identification code and inputs the identification code to the tag unit 100 attached to the product by a wireless method. The identification code is a unique code (unique ID) for each sales floor that is given so that an alarm can be managed for each sales floor when there are many sales floors in the same place.

When a specific code number (usually 1 to 2 bytes) is set in the code signal generator 200, a signal corresponding to an arbitrarily set number (corresponding to a unique identification code) is generated. At this time, by placing the tag provided at the sales floor close to the signal transmission range of the code signal generator, a code for each sales floor is set in the tag by a non-contact method. The code signal generator includes a code setting unit 240, which is preferably configured to be easily changed by an administrator using, for example, a DIP switch corresponding to a passive switch element. The code signal generation unit 100 periodically transmits a signal suitable for the set code number based on a predefined protocol as a magnetic field signal (LF) or a radio signal (RF).

The code signal generator 200 not only has a function of giving a code number to a tag, but also has a control function of setting / releasing tag mode information (boundary mode setting, alarm release, etc.) as necessary. .

Meanwhile, the code signal generator includes a state display unit 220, a storage unit 230, and a control unit (MCU) 250. The state display unit 220 outputs an operation state of the device. For example, the state display unit 220 has a display window and displays information such as normal input and error when a signal is input to the tag due to generation of a code. The storage unit 230 corresponds to a memory element and stores each unique identification code so that the information can be converted into data.

The code signal generator described above corresponds to a further adding device for adding an identification code to the tag unit 100. Of course, a large number of tag units can be easily managed (addition of an identification code) using the code signal generator, but a large number of tag units are not always managed using only the code signal generator. For example, the unique code can be managed so that the code number determined at the time of delivery is permanently used during the generation of the tag portion.

FIG. 2A is a block diagram of the tag unit in the self-sounding merchandise anti-theft system with wireless communication function according to the present invention, and FIG. 2B is a detailed diagram of the storage unit of the tag unit.

The self-sounding tag unit 100 according to the present invention has an alarm output function by itself and transmits the signal to a remote alarm receiver 300 described later when an alarm occurs.

The tag unit 100 stores a wire disconnection detection unit 110 that detects whether a product is stolen by using a wire or a switch structure, a control unit (MCU) 160 that controls signal processing and information processing based on detection of theft prevention, and stores a unique identification code. The storage unit 130, the sensitive device first signal receiving unit 140 that receives the signal from the store entrance / exit sensitive device and the code signal generator, and the product theft sensing information and the sensitive device signal reception information detected by the tag at the remote location. And a first signal transmission unit 150 that transmits to the apparatus. The tag unit 100 further includes an alarm display unit 120 that outputs an alarm sound or an alarm when an alarm signal is generated in the tag unit itself.

At this time, as described above, the unique identification code stored in the tag unit 100 may be specified and programmed when the tag unit is generated and stored in the storage unit, and is generated by the code signal generator 200. May be received and stored in the storage unit 130. Preferably, however, an administrator can provide individual identification based on management rules in the field applied to the anti-theft system using the code signal generator. It is preferable to input the unique identification code it has. Thereby, it is possible to ensure manageability (ease of managing the identification code of the manager in the area).

In addition, the tag unit 100 realizes operations in the order of wireless transmission, sound (beep), and lamp (LED) in order to suppress power consumption as much as possible. At this time, the control unit 160 controls the wireless transmission procedure so that the interval between the functions uses the minimum time required for charging and discharging the battery.

In addition, the control unit 160 is a low-power device that cuts off the power supply of the first signal receiving unit 140 in order to prevent battery crossing due to continuous sensing device signals during wireless transmission and battery exhaustion due to redundant duplication alarm processing. Implement communication functions.

On the other hand, the unique identification code stored in the storage unit for individual identification of the tag unit includes a fixed type identification code 131 storage region and a movable type identification code 132 storage region.

The fixed type identification code 131 and the movable type identification code are for adding the efficiency of identification information of the tag, the fixed type identification code is designated as a high-level concept identification code, and the movable type identification code is an auxiliary type. It is determined as an identification code.

For example, in the case of a fixed type identification code, the identification code of the local area is provided when leaving the factory, and an identification code that is input as a non-volatile structure and can be distinguished in a higher concept is provided.

On the other hand, the movable type identification code is an identification code that can be easily changed by the administrator via the code signal generator. For example, the fixed type identification code + the movable type identification code is input to the sales floor itself. It is input as an identification code of a subordinate concept.

Therefore, the identification code stored in the storage unit of the tag unit is composed of a fixed type identification code and a movable type identification code, and the two identification code areas are determined as volatile / non-volatile. In view of this, the expandability of the identification area can be ensured.

Each identification code area is determined in various ways depending on the system design method. In the case of a fixed identification code, it may be configured to be input when the tag portion is generated, or fixed. Both the mold and the movable mold are set so as to be systematically designed and determined so as to be controlled via a code signal generator or controlled by security management.

FIG. 3 is a block diagram showing an example of a remote alarm receiver in the self-sounding merchandise theft prevention system with wireless communication function according to the present invention, and FIG. 4 is a self-sounding merchandise theft with wireless communication function according to the present invention. FIG. 5 is a block diagram showing an example of a remote alarm receiver in the self-sounding merchandise anti-theft system with a wireless communication function according to the present invention.

The remote alarm receiver 300 receives a signal directly via wireless communication based on an alarm signal generated in the tag unit and outputs an alarm, and is in the area where the antitheft system is provided. The alarm signal received from the tag unit is output and monitored from a remote location.

The remote alarm receiver 300 includes a second signal receiver 310 that receives a radio signal output from a tag unit, a control unit (MCU) 360 that classifies received information and controls the entire remote alarm receiver, , The received data display unit 320 for outputting the classified information (unique number of each tag or arbitrary data information matched with the unique number) by itself such as text output, and an alarm signal based on the received signal And an alarm generation unit 330 for outputting.

Further, the remote alarm receiver 300 sets a code number via a DIP switch (similar to the code signal generator) or communication means so that a code number given for each sales floor can be designated. Is provided. The code setting unit 350 determines the reception available code of the remote alarm receiver. For example, the code setting unit 350 sets the operation range so that only the unique identification code is operated with the tag unit, and the assigned tag unit. The remote alarm receiver is set so as not to operate even if an alarm is activated on the remaining tag section (tag section having a non-region identification code).

As the code setting unit 350, an input unit such as a DIP switch is generally employed, but a method of directly programming the control unit (MCU) of the receiving apparatus can also be employed. It is recognized that the code number is set through the external input means.

If the code is set, the remote alarm receiver 300 processes only the tag information containing the code number set when the information received through the second signal receiving unit 310 is classified in the MCU. To. Through such a process, it becomes possible to select a burglar alarm at another sales floor. In other words, the alarm is generated in the receiver only when the alarm includes the same code number as the set code number.

  And the alarm setting part 331 is attached so that a user can set the alarm generation operation | movement of the receiver regarding the kind of alarm easily. Examples of alarm types include wire breakage or switch alarms, whole entrance / exit alarms, and alarms by exit / entry, and alarms are set by combining single or multiple alarms according to the type of alarm. Only in the MCU and output to the alarm generation unit.

For this reason, by using the alarm setting unit 331 to set an output alarm according to the type of alarm, it is possible to understand for what reason the alarm occurs.

As an additional function, the generated alarm information is sent to an external device such as a computer using separate communication (wired / wireless communication). For this purpose, the remote alarm receiver 300 is provided with an external device presence / wireless communication unit 370, and the attachment of the external device presence / wireless communication unit 370 enables the sales area manager's mobile phone, pager, mobile device. It is possible to provide a service that easily displays an alarm.

The self-sounding merchandise anti-theft system with a wireless communication function according to the present invention having such a configuration can output an alarm on the tag itself, and each tag portion is provided with an identification code. Since the identification code of the tag unit is recognized through a remote alarm receiver that receives the signal from the tag unit that generated the signal, there is an advantage that more systematic anti-theft management can be performed.

As mentioned above, although preferred embodiment for demonstrating the principle of this invention was described and illustrated, this invention is not limited to the as-is structure and action as illustrated and described in this way. Rather, those skilled in the art will recognize that many changes and modifications may be made to the present invention without departing from the spirit and scope of the appended claims. Accordingly, all such appropriate changes and modifications and equivalents should also be considered within the scope of the present invention.
