Description

  The present invention relates to a mobile phone use prevention device, and more particularly, to prevent a so-called “transfer fraud” from occurring in a predetermined area where an automatic teller machine (hereinafter referred to as ATM) is installed. The present invention relates to a mobile phone use prevention device for preventing use.

  In recent years, so-called “transfer fraud”, in which expensive cash is transferred using a mobile phone, has been rapidly increasing. As an example of such a “transfer fraud” technique, victims with poor mechanical knowledge (especially many elderly people) operate ATMs while talking on their mobile phones, and call themselves as traffic accident bills. There is a thing that transfers a large amount of cash to an account. Each financial institution puts a warning paper around the ATM, but it is difficult to say that a sufficient prevention effect has been obtained.

  Therefore, in Patent Document 1 below, a surveillance camera is installed in the ATM, and based on the behavior of the ATM user photographed by the surveillance camera, it is determined whether the user is likely to be scammed or not. An apparatus is described. If this device detects that ATM users have taken a picture of an ATM user with a camera, and the user has been operating the ATM for a long time while holding the mobile phone, it will be a victim of “transfer fraud”. It is determined that there is a high possibility of encounter.

  However, the device described in Patent Document 1 determines the presence or absence of damage by image processing. However, depending on the height of the ATM user or how to hold the mobile phone, a mobile phone is installed in the surveillance camera. There is a possibility that a situation such as not being photographed may occur, or there is a possibility that all of mobile phones having many shapes cannot be recognized as mobile phones reliably. That is, it is not reliable to determine whether or not a mobile phone is used by image processing, and there has been a problem that “transfer fraud” due to use of the mobile phone during ATM operation cannot be reliably prevented.

  The problem to be solved by the present invention is to ensure the use of a mobile phone in a predetermined area where the ATM is provided in order to prevent the occurrence of “transfer fraud” by operating the ATM while using the mobile phone. It is an object of the present invention to provide a mobile phone use prevention device that prevents the above-mentioned problem.

  In order to solve the above-described problems, the present invention provides a mobile phone use prevention apparatus for preventing use of a mobile phone in a predetermined area where an automatic teller machine is installed, and receiving radio waves in the predetermined area. And a determination means for determining whether or not the radio wave received by the reception means is a radio wave of a mobile phone, and when the determination means determines that the radio wave of the mobile phone has been received, The gist of the present invention is to further include at least one of warning generating means for prompting a warning to be sent to a monitoring person who monitors use of the mobile phone in the predetermined area.

  In this case, it is preferable that the receiving means has a plurality of receiving devices corresponding to radio waves having different frequency bands transmitted from various mobile phones in the predetermined area.

  In addition, the warning generation unit is configured to display a warning sound generation device that generates a warning sound, a lamp lighting device that lights a lamp, and a display that indicates that the use of a mobile phone is prohibited to a mobile phone user in the predetermined area. It suffices to have at least one of the devices.

  Furthermore, it is only necessary to further include area adjusting means for adjusting the size of the predetermined area by adjusting the receiving sensitivity of the receiving means.

  Moreover, it is only necessary to further include a call unit that enables a call between the mobile phone user and the supervisor in the predetermined area when the determination unit determines that the radio wave of the mobile phone has been received.

  Then, when the determination unit determines that the radio wave of the mobile phone has been received, it may further include a shooting unit that takes a picture of the mobile phone user in the predetermined area.

  According to the mobile phone use preventing apparatus according to the present invention, the mobile phone in the predetermined area where the ATM is installed is used by the receiving means and the discriminating means for discriminating whether the radio wave is from the mobile phone. Whether or not there is a person can be detected with certainty, and after the detection, the mobile phone user is warned, or for example, is notified to a monitor such as a security company. Use of the mobile phone in the area is prevented. In other words, it is prevented to operate the ATM while making a call on the mobile phone, so that the occurrence of a “transfer fraud” that makes the ATM skillfully operate while making a call on the mobile phone and transfers the cash to its own account. Is prevented.

  In addition, since the frequency band of the radio wave used differs depending on the telecommunications carrier providing the mobile phone service, all types of mobile phones can be provided with a receiving device that can receive radio waves of each frequency band. The use of the telephone can be surely prevented.

  Further, the warning means may actually use a mobile phone by alerting the user with a warning sound or a lamp, displaying a message that the mobile phone is prohibited on the display device, or using a combination thereof. It is possible to stop the use of the mobile phone by those who have been scammed.

  Furthermore, if an area adjusting means for adjusting the size of the predetermined area for preventing the use of the mobile phone is further provided, the use of the mobile phone can be prevented depending on the number of ATM users and the installation environment of the ATM. The size of the area to be performed can be set freely, and erroneous detection and the like are prevented.

  In addition, when the determining means determines that the radio wave of the mobile phone has been received, a calling means for enabling a call between the mobile phone user and the supervisor and a photographing means for photographing the state of the mobile phone user are provided. This makes it easy to make a call with the mobile phone user or to determine whether the mobile phone user is suffering from a “transfer fraud” from the state of the mobile phone user.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Here, FIG. 1 is an external perspective view of the mobile phone use preventing apparatus 1 according to the embodiment of the present invention, and FIG. 2 is a block diagram for explaining the configuration of the mobile phone use preventing apparatus 1.

  The mobile phone use prevention device 1 according to the present embodiment is a device for preventing the use of a mobile phone in a predetermined area where an ATM is installed, and receives and detects radio waves in the predetermined area. Means 10 for determining whether the radio wave received by the receiving means 10 is a radio wave of a mobile phone, and the mobile phone when the discrimination means determines that the received radio wave is a radio wave of the mobile phone Warning generating means 30 for prompting the user to make a warning, and a supervisor who monitors the use of the mobile phone in a predetermined area where the ATM is installed (for example, from a financial institution in which this ATM is installed or such a financial institution) And a reporting means 40 for reporting to a security company entrusted with security.

  In the present embodiment, the receiving means 10 includes three receiving devices 11 to 13 as shown in FIG. Receiving devices 11 to 13 receive signals from antennas 11a to 13a that capture radio waves from a mobile phone, first filters 11b to 13b and second filters 11c to 13c that shield radio waves in a predetermined frequency band, respectively. There are first amplifiers 11d to 13d and second amplifiers 11e to 13e to be amplified, and detectors 11f to 13f for detecting a signal that has passed through the second filter.

  The mobile phone use prevention device 1 according to the present embodiment includes the plurality of receiving devices 11 to 13 as described above. The communication carriers that provide the mobile phone service have different frequency bands (for example, 800 MHz band, This is because signals of 1500 MHz band and 2000 MHz band are used. That is, each of the receiving devices 11 to 13 is assigned a frequency band used by one communication carrier, and among radio waves captured by the antennas 11a to 13a, radio waves of frequencies other than the assigned frequency band are It is configured to be excluded by the first filters 11b to 13b and the second filters 11c to 13c. With such a configuration, the mobile phone use prevention apparatus 1 according to the present embodiment can prevent the use of mobile phones by all communication carriers.

  Here, in the present embodiment, after the radio waves captured by the antennas 11a to 13a are passed through the first filters 11b to 13b, they are amplified by the first amplifiers 11d to 13d, and again the second filters 11c to 11c. 13c is passed and amplified by the second amplifiers 11e to 13e. The double filter is used to reduce the intensity of radio waves generated from various devices in the surrounding area by passing the double filter and generate from the mobile phone. This is because the transmission radio wave of the mobile phone can be reliably detected by widening the difference from the intensity of the transmission radio wave to be transmitted.

  Note that the number of receiving devices included in the receiving unit 10 configured in this way can be changed as appropriate according to an increase or decrease in the number of communication carriers, a change in frequency band used by the communication carriers, and the like. .

  The signals that pass through the first filters 11b to 13b and the second filters 11c to 13c, are amplified by the first amplifiers 11d to 13d and the second amplifiers 11e to 13e, and are detected by the detectors 11f to 13f, A micro control unit (MCU) 20 serving as a discrimination means determines whether or not the radio wave is from a mobile phone.

  When it is determined that the radio wave received by the micro control unit 20 is from a mobile phone, that is, when the use of the mobile phone is confirmed within a predetermined area where the ATM is installed, the use of the mobile phone In order to stop the operation, the warning generating means 30 and the calling means 40 are activated. These specific operations will be described in the operation flow of the mobile phone use preventing apparatus 1 below.

  Hereinafter, the operation flow of the mobile phone use prevention apparatus 1 will be described with reference to the flowchart of FIG. 3 in addition to FIG. 1 and FIG.

  First, when the mobile phone use prevention apparatus 1 is turned on, the apparatus is initialized (S1). Next, the intensity of average RF (Radio Frequency) radio waves in the installation environment of the apparatus is measured (S2).

  Next, various initial settings are performed by the user operating the operation buttons. As shown in FIG. 1, this setting is performed with the MODE button 3, the UP button 4, the DOWN button 5, and the SET button 6 provided on the case body 2 of the mobile phone use prevention apparatus 1 (S3 to 6). Here, a detection range for prohibiting the use of the mobile phone, a warning method by a warning generation unit 30 described later, and a telephone number of a notification destination by the notification unit 40 are set.

  For example, the mobile phone use prevention apparatus 1 according to the present embodiment can freely set the reception sensitivity of the reception means 10 (reception apparatuses 11 to 13) by the micro control unit 20 that is the determination means and the area adjustment means. It is possible to do. In other words, the size of a predetermined area for preventing the use of a mobile phone can be freely adjusted by the operation of the operation buttons according to the number of ATM users and the installation environment of the ATM (for example, prevention of use of the mobile phone) Since it can be adjusted within a radius of 1 m to 20 m from the installation position of the apparatus 1, it is possible to prevent erroneous detection such as capturing radio waves of a passer's mobile phone. Since ATMs have recently been installed in many convenience stores and the like, such a function can prevent reception of radio waves generated from mobile phones of convenience store users who do not use ATMs. is there.

  Then, the measurement of the radio wave in the installation environment is actually started, and the radio wave intensity received by the receiving means 10 (receiving devices 11 to 13) is set to a predetermined threshold value (the average RF radio wave intensity measured in S2 and the predetermined predetermined value set). The threshold value becomes smaller as the predetermined area becomes larger.) It is judged by the micro-control unit 20 (discriminating means) that the radio wave is larger than the predetermined area. In the case (S7 “YES”), the process proceeds to S8, and measures are taken to stop the use of the mobile phone.

  In the present embodiment, a warning is first issued by the warning generation means 30 (S8 “Alarm”). The warning generating means 30 includes a warning sound transmitting unit 32 (warning sound generating device), an LED (lamp lighting device) 34, and a display device (LCD) 36. When the use of the mobile phone is confirmed, the micro control unit 20 (discriminating means) sounds a buzzer (warning sound) from the warning sound transmitting unit 32, turns on the LED 34, or causes the display device 36 to carry the mobile phone near the ATM. By displaying that the use of the telephone is prohibited (S9), the mobile phone user is alerted.

  This warning method is an example, and can be changed as appropriate. For example, any one of the above warnings may be performed, or all the above warnings may be performed.

  When a warning is issued by the warning generation means 30, a notification is made to the supervisor by a notification means 40 comprising a DTMF (Dual Tone Multiple Frequency) transmitter 42, a DTMF receiver 44, and a voice IC 46 (S9 "Telephone") ). Specifically, when any of the above warnings is issued by the warning generating means 30 for the first time after the initial setting of the mobile phone use preventing apparatus 1 (S10 “YES”), the initial setting is performed by the DTMF transmitter 42. A call is made to the telephone number of the supervisor set in (S11).

  On the other hand, when the warning by the warning generation means 30 is the second time or later (S10 “NO”), it is determined whether or not one minute or more has elapsed since the previous warning (S12). By providing such a determination, according to the present embodiment, when the radio wave of the mobile phone is detected a plurality of times in a short time and the warning is generated by the warning generating means 30 a plurality of times, the user of the mobile phone is the same person In spite of this, it is prevented that the notification is repeated every time a warning is issued. That is, when one minute or more has not yet passed since the previous warning (“NO” in S12), only the radio wave from the mobile phone used by the same person has been received again, and the first warning has occurred. It is determined that the report has already been sent to the observer at that time, and the report is not sent again.

  On the other hand, when one minute or more has passed since the previous warning (“YES” in S12), a person who is different from the person who used the mobile phone at the time of the previous warning newly uses the mobile phone. The DTMF transmitter 42 makes a call to the telephone number of the supervisor set in the initial setting (S11).

  In this embodiment, the criterion for determining whether or not the radio wave is from a mobile phone used by the same person is whether or not one minute has passed since the previous warning occurred. Is possible. For example, this time may be set appropriately according to the number of ATM users.

  When a call is made in S11, the calling timer starts counting (S13). After the call, the monitor picks up the handset and the response sound is caught (S14 “YES”). From the voice IC 46, the voice guidance to the effect that the mobile phone user is present to the monitor, for example, “mobile in X bank ATM”. A pre-recorded voice message such as “There is a telephone user” is sent (S15). In the present embodiment, in order to ensure that the notification is made, the voice guidance is sent twice. That is, it is determined whether or not the voice guidance is the second time in S16, and if it is the second time (S16 “YES”), the calling timer stops counting (S17) and the notification ends (S18). . On the other hand, when the voice guidance is the first time (S16 “NO”), the process returns to S15 and the voice guidance is sent again.

  In S14, if for some reason the supervisor cannot answer the call and the response sound is not caught (S14 “NO”), when the call timer counts 50 seconds (S19 “YES”), the call timer Is stopped (S17), and the notification is terminated (S18). However, even in such a case, there is no problem because the report destination is recorded in the incoming call history of the telephone held by the supervisor. In other words, the call timer is provided in order to prevent the watcher from calling on endlessly even when the monitor is absent for some reason.

  Thus, according to the mobile phone use preventing apparatus 1 according to the present embodiment, the ATM is installed by the receiving unit 10 and the micro control unit 20 (discriminating unit) that discriminates whether or not the radio wave is from the mobile phone. It is possible to reliably detect whether or not there is a person using the mobile phone in a predetermined area. After the detection, a warning is issued to the mobile phone user by the warning generation means 30, for example, by the notification means 40. Since it is configured to notify a supervisor such as a security company, use of the mobile phone in the predetermined area is prevented. In other words, it is prevented to operate the ATM while making a call on the mobile phone, so that the occurrence of a “transfer fraud” that makes the ATM skillfully operate while making a call on the mobile phone and transfers the cash to its own account. Is prevented.

  As described above, the mobile phone use prevention device 1 prevents the use of the mobile phone in the vicinity of the ATM by the warning by the warning generation means 30 and the notification to the supervisor by the notification means 40, but further its use prevention effect In order to improve the above, it is possible to provide the following additional functions.

  For example, as shown in the block diagram of FIG. 4, the calling means 50 can be provided in the mobile phone use prevention apparatus 1. The call means 50 includes a speaker 52, a microphone 54, and an audio unit (A / D (analog / digital) converter) 56. By providing such a calling means 50, when it is confirmed that the mobile phone is used in a predetermined area around the ATM, the supervisor can talk to the mobile phone user through the speaker 52. In addition, since the voice of the mobile phone user is sent to the supervisor through the microphone 54, the supervisor knows what kind of conversation the mobile phone user is talking on the mobile phone. You can determine whether you are suffering damage. Further, after the mobile phone user stops using the mobile phone, the supervisor and the mobile phone user can talk through the speaker 52 and the microphone 54.

  Further, in addition to the calling means 50, a photographing means 60 (video camera) for photographing the state of the mobile phone user can be provided. When it is confirmed that the cellular phone is used in a predetermined area around the ATM, the photographing unit 60 is driven to photograph the state of the cellular phone user. The photographed video is transmitted to the supervisor by the micro control unit 20 as a transmission means. As a result, the supervisor can determine whether or not he / she is suffering from “transfer fraud” from the state of the mobile phone user. In addition, the supervisor can more reliably and promptly determine whether or not the “transfer fraud” has been damaged by considering the video and the voice of the mobile phone user that can be acquired by the calling means 50 together. .

  As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to the said embodiment at all, A various change is possible in the range which does not deviate from the summary of this invention. For example, in this embodiment, in order to prevent so-called “transfer fraud”, the use of a mobile phone in a predetermined area around an ATM is prevented. However, the use of a mobile phone in a hospital or train must be prevented. It can also be used in other places and facilities that must be used.
