Description

  The present invention relates to an improvement in a security system comprising an electronically controlled locking device, a portable portable communication terminal, and an indoor communication device.

  For example, Patent Document 1 discloses a crime prevention system including an electronically controlled locking device, a portable portable communication terminal, and an indoor installation type information communication device.

  The collective housing security system disclosed in Patent Document 1 receives a call when a visitor visits a resident's house by calling a resident's landline or mobile phone from the vicinity of the resident's house. The resident decides whether to enter the room, the resident calls the manager's telephone device again, determines whether this call is from the resident, and determines whether the phone is from the resident. The door is opened only in the case of a telephone. At this time, the determination process in the management-side telephone device uses the caller ID notification service (number display) to confirm the telephone number of the caller, and this telephone number is registered in the storage means of the management-side telephone device. It is automatically done by searching whether or not.

  Therefore, when a resident who is away from home returns home and opens the door, the resident should go out by bringing his / her mobile phone and call the management phone from the vicinity of the resident's home. Can be opened automatically.

  However, when using a mobile phone, it is common to register in advance the telephone number of the contact (phone number of the management-side telephone device), and the information registered in the mobile phone (the telephone number of the contact) Mobile phone-specific locking systems that restrict the use of mobile phones are rarely used for the convenience of the owner, so if the mobile phone is lost or stolen, The possibility that the three parties use the mobile phone to open the door of the resident's house without permission cannot be denied.

  In addition, when a legitimate user of the mobile phone calls the management-side telephone device by an operation, there is a disadvantage that the door remains open.

JP 2004-248273 A (paragraph numbers 0041 and 0042)

  An object of the present invention is to improve the inconvenience of the prior art, and when a portable mobile communication terminal such as a mobile phone constituting a part of the crime prevention system is lost, further, portable mobile communication such as a mobile phone. An object of the present invention is to provide a crime prevention system in which security can be guaranteed even when a legitimate user performs an erroneous operation on a terminal.

The crime prevention system of the present invention is a crime prevention system comprising an electronically controlled locking device installed on a door, a portable portable communication terminal, and an indoor installation type information communication device having a function of communicating with the portable communication terminal. In order to achieve the above-mentioned problem,
In the locking device,
A reception permission signal for allowing the information communication device to accept identification information unique to the mobile communication terminal transmitted in response to a transmission operation using the mobile communication terminal as a candidate for an unlock operation acceptance permission signal; A reception permission signal transmitting means for transmitting to the information communication device;
A reception permission signal transmission switch for operating the reception permission signal transmission means;
An unlock operation acceptance start signal receiving means for receiving an unlock operation acceptance start signal transmitted from the information communication device;
Only when the unlocking operation acceptance start signal receiving means has received the unlocking operation acceptance start signal, after the unlocking operation acceptance start signal receiving means has received the unlocking operation acceptance start signal, Release operation permission means for allowing acceptance of a lock release operation performed on the operation unit of the locking device in a range ;
Suitability determination means for detecting the unlocking operation performed on the operation unit and determining the propriety of the unlocking operation;
A door lock unit that is unlocked when the suitability determining unit determines that the unlocking operation performed on the operation unit is appropriate; and
In the information communication device,
Storage means for storing identification information allowing acceptance of an unlocking operation performed on the operation unit;
A reception permission signal receiving means for receiving a reception permission signal from the reception permission signal transmitting means;
Only when the reception permission signal receiving means has received the reception permission signal, after the reception permission signal receiving means has received the reception permission signal, the identification information is unlocked within a preset time range. Identification information standby means for receiving as candidates,
It is determined whether or not the identification information received by the identification information standby means matches the identification information stored in the storage means, and the lock release operation acceptance start signal receiving means is unlocked only when they match. An unlock operation acceptance start signal transmission means for transmitting an operation acceptance start signal is provided.

In the above configuration, when the reception permission signal transmission switch of the electronically controlled locking device installed in the door is operated by the user's hand, first, the reception permission signal transmission means of the locking device is activated, and the locking device A reception permission signal is transmitted to the indoor communication device.
When this reception permission signal is received by the reception permission signal receiving means of the indoor installation type information communication device, the identification information standby means of the information communication device starts to operate. Then, the identification information standby means receives the identification information transmitted in response to the transmission operation using the mobile communication terminal as a candidate for the unlock operation acceptance permission signal.
Here, when a user performs a transmission operation on an indoor communication device using a portable mobile communication terminal owned by the user, identification information unique to the mobile communication device is stored in the indoor communication device. The information communication device receives the identification information as a candidate for an unlock operation acceptance permission signal.
Next, the unlocking operation acceptance start signal transmission means of the information communication device is activated, and the identification information received by the identification information waiting means is an identification permitting acceptance of the unlocking operation performed on the operation unit of the locking device. It is determined whether or not it matches the identification information stored in the storage means as information, and only when they match, the lock release operation reception start signal is transmitted to the lock release operation reception start signal reception means of the locking device (match) Otherwise, the unlock operation acceptance start signal is not transmitted).
Then, when the unlocking operation acceptance start signal receiving means of the locking device receives the unlocking operation acceptance start signal, the unlocking operation permission means of the locking device accepts the unlocking operation performed on the operation unit of the locking device. Allow.
The operation unit of the locking device accepts the unlocking operation only when the unlocking operation permitting unit allows the unlocking operation to be accepted, and the propriety determining unit of the locking device detects the unlocking operation performed on the operating unit. Thus, it is determined whether or not the unlocking operation is appropriate, and the door lock unit is unlocked only when the appropriateness determining unit determines that the unlocking operation is appropriate.
As described above, acceptance of the unlocking operation performed on the operation unit of the locking device is permitted because the reception permission signal transmission switch of the locking device installed in the door is operated and the locking device A portable communication terminal having identification information preliminarily stored in the storage means as an object for accepting an unlocking operation performed on the operation unit, that is, a portable possessed by a user who has the authority to unlock the door locking means. Only when a transmission operation is performed from the communication terminal, and the door lock means is actually unlocked when an appropriate unlocking operation is performed on the operation unit of the locking device. Limited.
In other words, if a user who has the authority to unlock the door lock means loses his / her own mobile communication terminal or is stolen, the third party who acquired this mobile communication terminal can lock the device. Although it is permissible until the unlocking operation is attempted on the operation unit of this device, it is actually difficult for this third party to perform an appropriate unlocking operation. The risk of inadvertently releasing the locking means is greatly reduced.
In addition, if a user who has the authority to unlock the door lock means misoperates his / her own mobile communication terminal, identification information unique to the mobile communication terminal is transmitted to the indoor communication device. However, unless the reception permission signal is transmitted to the information communication device by the operation of the reception permission signal transmission switch of the locking device installed in the door, the identification information standby means of the information communication device However, since it is not accepted as a candidate for the unlocking operation acceptance permission signal, the operation unit of the locking device accepts an unlocking operation by a third party due to an inadvertent misoperation of the mobile communication terminal, and the door locking means The risk of being released is greatly reduced.

  As described above, when a user who has the authority to release the locked state of the door lock unit mistakenly operates his / her own mobile communication terminal, the identification information unique to this mobile communication terminal is the indoor-installed information communication device. However, there is a possibility that a third party has operated the reception permission signal transmission switch of the locking device before this erroneous operation is performed. It has the authority to release the lock state of the door lock means by limiting the time for the identification information waiting means to receive the identification information as a candidate for the lock release operation acceptance permission signal, starting from the operation point of the reception permission signal transmission switch. Risk that the unlocking operation acceptance start signal transmitting means inadvertently transmits the unlocking operation acceptance start signal based on the identification information transmitted when the user misoperates the mobile communication terminal owned by the user, that is, The risk that a third party operates an operation unit that is permitted to accept the unlocking operation can be greatly reduced.

  By limiting the time during which the unlocking operation can be accepted, the risk of a third party releasing the door lock means can be further reduced.

The crime prevention system of the present invention transmits a reception permission signal to an indoor communication device by operating a reception permission signal transmission switch provided in an electronically controlled locking device installed in a door, and this reception permission The identification information standby means is allowed to receive unique identification information transmitted in response to a transmission operation using a portable portable communication terminal by a signal as identification information that is a candidate for an unlock operation acceptance permission signal. During this time, only when the identification information received from the mobile communication terminal matches the proper identification information stored in advance in the storage means of the information communication device, the lock release device accepting start signal is transmitted to the locking device, and the operation of the locking device is performed. If the unlocking operation is performed on the operation unit of the locking device, the lock operation performed on the operation unit is permitted. Since the door lock means is unlocked only when the release operation is appropriate and the release operation is appropriate, the lock release operation performed on the operation unit of the locking device can be accepted. Permitted is that the reception permission signal transmission switch of the locking device installed in the door is operated, and is stored in advance in the storage means as an object to receive the unlocking operation performed on the operation unit of the locking device. Only when a transmission operation is performed from a portable communication terminal having identification information, that is, a portable communication terminal owned by a user having the authority to release the lock state of the door lock means, and actually locking the door lock means The state is released only when an appropriate unlocking operation is performed on the operation unit of the locking device.
Therefore, a mobile communication terminal owned by a user who has the authority to release the lock state of the door lock means is acquired by a third party, and this third party tries to perform an unlock operation on the operation unit of the locking device. Even if it becomes possible, there is no worry that the locked state of the door lock means is immediately released, and the risk that the door lock means is inadvertently released due to loss or theft of the mobile communication terminal can be reduced.
When a user who has the authority to release the lock state of the door lock means erroneously operates a mobile communication terminal owned by the user, identification information unique to the mobile communication terminal is transmitted to an indoor communication device. This is inevitable, but unless the reception permission signal is transmitted to the information communication device by the operation of the reception permission signal transmission switch of the locking device installed in the door, the identification information standby means of the information communication device is appropriate identification information. However, since this is not accepted as a candidate for the unlocking operation acceptance permission signal, the possibility of a third party releasing the door lock means by using an inadvertent misoperation of the mobile communication terminal is reduced. be able to.

The same information as the card information) is stored and compared with the personal identification number or magnetic card or IC card information input by the unlocking operation.

  FIG. 4 is a conceptual diagram showing the hardware of the facsimile machine 5 in a simplified manner, and FIG. 5 is a functional block diagram showing an outline of the configuration of the facsimile machine 5.

As shown in FIG. 4, the facsimile machine 5 is used to store a CPU 19 for arithmetic processing, a ROM 20 that stores a control program for the CPU 19, a RAM 21 that is used for temporary storage of data, and transmission / reception data. A non-volatile memory 22 is provided.
Further, the input / output circuit 23 of the CPU 19 is connected to a facsimile control unit 24 for driving and controlling basic elements of the facsimile apparatus 5 such as a scanner and a printer (not shown), and is connected to a public telephone line or a dedicated line for facsimile data. A data transmission / reception circuit 25 for transmitting / receiving and a transmission / reception circuit 26 for communicating with the transmission / reception circuit 16 of the locking device 3 are connected.
The display device 27 and the operation panel 28 including a liquid crystal display or the like are well-known elements for realizing the basic functions of the facsimile apparatus 5, as with the facsimile control unit 24.

  The transmission / reception circuit 26 is based on the Bluetooth wireless communication standard, and functions as a reception permission signal receiving unit 26a that receives a reception permission signal transmitted from the locking device 3, as shown in FIG. Further, the data transmission / reception circuit 25 connected to the public telephone line or the dedicated line is transmitted to the mobile phone 4 in response to the transmission operation only when the reception permission signal receiving unit 26a receives the reception permission signal. It functions as identification information waiting means 25a that receives identification information as a candidate for an unlock operation acceptance permission signal.

  The non-volatile memory 22 functions as a storage unit 22 a for storing identification information that allows acceptance of an unlocking operation performed on the operation unit 15 of the locking device 3, and the transmission / reception circuit 26 is configured by the locking device 3. A part of the unlocking operation acceptance start signal transmitting means 26b for transmitting the unlocking operation acceptance start signal is configured.

  Then, the CPU 19 determines whether or not the identification information received by the other part of the unlocking operation acceptance start signal transmission unit 26b, that is, the identification information waiting unit 25a matches the identification information stored in the storage unit 22a. However, it functions as a determination unit that permits transmission of the unlock operation acceptance start signal only when they match.

  Since the configuration of the mobile phone 4 is the same as the conventional one, the description thereof is omitted. In this embodiment, the phone number of the mobile phone 4 is used as identification information unique to the mobile phone 4, and this phone number can be received by using a known caller number notification service (number display). Are displayed on the display 27. This telephone number is identification information unique to the mobile phone 4 transmitted in response to a transmission operation using the mobile phone 4.

  In the nonvolatile memory 22 functioning as the storage means 22a, a user who has the authority to release the lock state of the locking device 3 by manual input operation from the operation panel 28, for example, the telephone number of the mobile phone 4 owned by the family Remember (multiple).

  6 is a flowchart showing an outline of processing executed by the CPU 8 of the locking device 3. FIG. 7 is a security system except for basic functions such as facsimile transmission / reception among the processing executed by the CPU 19 of the facsimile device 5. 2 is a flowchart showing an outline of processing directly related to operation of No. 1;

  Next, the overall processing operation of the crime prevention system 1 of the present embodiment will be specifically described with reference to these drawings.

  The CPU 8 of the locking device 3 initializes the value of the state storage flag F1 to 0 in the initialization process at power-on (step a1), and then determines whether or not the value of the state storage flag F1 is held at 0 (step step 1). a2) and waiting for the user to operate the reception permission signal transmission switch 18 of the locking device 3 while repeatedly executing the determination process of whether or not the reception permission signal transmission switch 18 is operated (step a3). To do.

  Here, when the user operates the reception permission signal transmission switch 18, the CPU 8 detects this operation in the determination process of step a3, operates the transmission / reception circuit 16 functioning as the reception permission signal transmission means 16a, and operates the facsimile machine 5. (Step a4), an allowable value is set in the timer T0 that defines the allowable operation time after the operation of the reception permission signal transmission switch 18, and time measurement is started (step a5), and the state storage flag F1 Is set to 1, it stores that the reception permission signal transmission switch 18 has been operated (step a6).

  Next, the CPU 8 determines whether or not the time measured by the timer T0 has reached the allowable operation time (step a7). At this time, the time measured by the timer T0 does not reach the allowable operation time. The process proceeds to the determination process of step a2, and it is determined whether or not the value of the state storage flag F1 is held at zero.

  Since 1 is already set in the state storage flag F1, the determination result in step a2 is false, and then the CPU 8 determines whether or not the value of the state storage flag F1 is 1 (step a8).

  In this case, since the value of the state storage flag F1 is 1, the CPU 8 further determines whether or not a lock release operation acceptance start signal is transmitted from the facsimile machine 5 (step a9).

  At this time, since the lock release operation acceptance start signal has not been received yet, the determination result of step a9 is false, and hereinafter, the CPU 8 performs the steps a2 and a8 on the condition that the timer T0 has not reached the operation allowable time. , Steps a9 and a7 are repeatedly executed to wait for the unlocking operation acceptance start signal to be transmitted from the facsimile apparatus 5.

  On the other hand, the CPU 19 of the facsimile apparatus 5 initializes the value of the state storage flag F2 to 0 in the initialization process at power-on (step b1), and determines whether or not the value of the state storage flag F2 is held at 0 (step b1). b2), while waiting for the reception permission signal to be transmitted from the locking device 3 while repeatedly executing the determination process of whether or not the reception permission signal has been transmitted from the locking device 3 (step b3), The reception permission signal transmitted from the locking device 3 as described above is detected by the CPU 19 through the transmission / reception circuit 26 functioning as the reception permission signal receiving means 26a in the determination process of step b3.

  The CPU 19 that has detected the reception permission signal sets an allowable value to the timer T2 that defines the operating time of the identification information waiting unit 25a after the reception permission signal receiving unit 26a receives the reception permission signal, and starts measuring time. (Step b4) By setting 1 to the state storage flag F2, it is stored that the operation of the identification information waiting means 25a is started (Step b5).

  Next, the CPU 19 determines whether or not the time count of the timer T2 has reached the allowable operation time (step b6). At this time, the time count of the timer T2 does not reach the allowable operation time. The process proceeds to the determination process of step b2, and it is determined whether or not the value of the state storage flag F2 is held at zero.

  Since 1 is already set in the state storage flag F2, the determination result in step b2 is false, and then the CPU 19 determines whether there is an incoming call from the mobile phone 4 (step b7). On the condition that the time count of T2 has not reached the allowable operation time, the determination process of step b2, step b7, and step b6 is repeatedly executed to wait for an incoming call from the mobile phone 4.

  The user who has operated the reception permission signal transmission switch 18 of the locking device 3 as described above repeats the waiting time, that is, the CPU 8 of the locking device 3 repeats the determination processing of step a2, step a8, step a9, and step a7. The mobile phone 4 is operated using the standby time to be executed and the standby time in which the CPU 19 of the facsimile apparatus 5 repeatedly executes the determination processing in step b2, step b7, and step b6, and a call is made to the facsimile apparatus 5. At this time, a telephone number which is identification information unique to the mobile phone 4 is transmitted to the facsimile machine 5 using a caller ID notification service (number display).

  In this way, the identification information transmitted from the mobile phone 4 before the time measured by the timer T2 reaches the allowable operating time of the identification information waiting means 25a, that is, the telephone number unique to the mobile phone 4, is determined by the determination process in step b7. Then, the data is detected by the CPU 19 of the facsimile apparatus 5 via the data transmission / reception circuit 25 functioning as the identification information waiting means 25a.

  The CPU 19 that has received the telephone number that is a candidate for the unlocking operation acceptance permission signal once initializes the value of the telephone number search index i to 0 (step b8), and then increments the value of the index i by 1 again. (Step b9) Based on the current value of the telephone number search index i, the i-th telephone number stored in the non-volatile memory 22 functioning as the storage means 22a is read (Step b10). It is determined whether or not the telephone number received in the process of b7 matches (step b11). If not, the current value of the telephone number search index i is stored in the nonvolatile memory 22 It is determined whether or not the total number n has been reached (step b12).

  If the current value of the telephone number search index i has not reached the total number n of telephone numbers, the CPU 19 functioning as a determination unit in the unlocking operation acceptance start signal transmission unit 26b determines that the current value of the index i is the total number n of telephone numbers. If not, step b9 to step b12 are repeatedly executed in the same manner as described above.

  Here, when the determination result of step b11 is true, the telephone number that matches the telephone number received in the process of step b7 is stored in the nonvolatile memory 22, that is, the locking device 3 This means that the user who has operated the mobile phone 4 before and performed the transmission operation is a user who has the authority to release the lock state of the locking device 3, such as a member of the family. After the transmission / reception circuit 26 constituting the main part of the release operation acceptance start signal transmitting means 26b is operated to transmit the lock release operation acceptance start signal to the locking device 3 (step b13), the value of the state storage flag F2 is initialized to 0. (Step b1) and return to the initial standby state.

  On the other hand, if the determination result in step b12 is true, even if all the telephone numbers stored in the nonvolatile memory 22 are searched, the telephone that matches the telephone number received in the process in step b7 That the number is not stored, that is, the user who has operated the mobile phone 4 in front of the locking device 3 to perform the transmission operation is not a user who has the authority to unlock the locking device 3, or This means that the incoming call by the normal facsimile transmission operation has been confirmed, so the CPU 19 determines again whether or not the time of the timer T2 has reached the allowable operation time of the identification information waiting means 25a (step b6) If the time measured by the timer T2 has not reached the allowable operation time of the identification information standby unit 25a, the process returns to the process of step b2 again, and the operation of the identification information standby unit 25a is permitted. It waits for new incoming call time range (step b2, Step b7, step b6).

  That is, even when an incoming phone number that is not stored in the non-volatile memory 22 is confirmed, the operation of the identification information waiting means 25a is not immediately prohibited, but within the allowable operating time range. This means that all incoming calls are recognized as candidates for the unlock operation acceptance permission signal, and this prevents the operation of the identification information waiting unit 25a from being caused by a normal facsimile transmission operation, that is, an incoming call that does not match the identification information. The occurrence of harmful effects such as

  On the other hand, if the time of the timer T2 reaches the allowable operation time of the identification information waiting means 25a without retrieving the telephone number that matches the telephone number received in the process of step b7 from the nonvolatile memory 22, in short, If the determination result of step b6 is true without the determination result of step b11 being true, the reception permission signal is transmitted by mischief to the reception permission signal transmission switch 18 of the locking device 3, and the identification information waiting means This means that the operation of 25a has been started or a user who is not authorized to release the lock state of the locking device 3 is going to perform a door lock release operation, and thus functions as the identification information waiting means 25a. The CPU 19 stops the operation of recognizing the incoming telephone number as a candidate for the unlock operation acceptance permission signal, and initializes the value of the state storage flag F2 to 0. And (step b1), to return to the initial standby state. In this case, the unlock operation acceptance start signal is not transmitted.

  Here, when the user who operates the mobile phone 4 in front of the locking device 3 and performs the transmission operation is a user who has the authority to release the locked state of the locking device 3, that is, locks from the facsimile device 5. When the release operation acceptance start signal is transmitted, the lock release operation is performed in the determination process of step a9 by the CPU 8 of the locking device 3 that repeatedly executes the determination processes of step a2, step a8, step a9, and step a7. A reception start signal is detected.

  The CPU 8 that has detected the unlock operation acceptance start signal defines the operation time of the release operation permission means 8a after the transmission / reception circuit 16 functioning as the unlock operation acceptance start signal receiving means 16b receives the unlock operation acceptance start signal. The timer T1 is set to a permissible value to start measuring time (step a10), and the state storage flag F1 is set to 2 to store that the operation of the release operation permitting means 8a is started (step a11). Then, the user is informed by the lighting of the alarm lamp 17 that the acceptance of the unlocking operation for the operation unit 15 is permitted (step a12).

  Then, in the same manner as described above, it is determined whether or not the time measured by the timer T0 has reached the allowable operation time (step a7). If the time measured by the timer T0 has not reached the allowable operation time, the processing of step a2 is performed again. Return.

  In this case, since the value of the state storage flag F1 is 2, the determination results of step a2 and step a8 are both false, and the CPU 8 further operates the timer T1 that defines the operation time of the release operation permission means 8a. It is determined whether or not the permissible time has been reached (step a13). If the permissible operation time has not been reached, it is determined whether or not the unlocking operation has been performed on the operation unit 15 (step a14).

  If the unlocking operation is not performed, the timer T0 does not reach the allowable operation time, and the timer T1 does not reach the allowable operation time of the unlocking operation permitting means 8a. Steps a2, step a8, step a13, step a14, and step a7 are repeatedly executed to wait for a lock release operation to be performed on the operation unit 15.

  The allowable operation time set in the timer T0 is longer than the allowable operation time of the release operation permission means 8a set in the timer T1, and is set in the timer T2 that defines the operation time of the identification information waiting means 25a. The allowable operation time is shorter than the allowable operation time set in the timer T1, and has a relationship of T2 <T1 <T0.

  In this way, while the determination process of step a2, step a8, step a13, step a14, and step a7 is repeatedly executed, the unlocking operation for the operation unit 15, that is, the password input operation using the numeric keypad or the card When the authentication information input operation using the reader is performed, the CPU 8 functioning as the suitability determination means 8b detects this in the determination process of step a14, and the password stored in the nonvolatile memory 11 or the authentication code is detected. The information is read out and compared with the personal identification number and authentication information input in the process of step a14, and it is determined whether or not they match (step a15).

  If both match and the determination result in step a15 is true, that is, if it is determined that an appropriate unlocking operation has been performed on the operation unit 15, the function determination unit 8b functions. The CPU 8 outputs an unlock command to the lock control circuit 14, and the lock control circuit 14 switches the door lock means 13 from the locked state to the unlocked state to unlock the door 2 (step a16). Then, the CPU 8 turns off the alarm lamp 17 (step a17), initializes the state storage flag F1 to 0 (step a1), and returns to the initial standby state.

  On the other hand, if the determination result in step a15 is false and it is clear that an improper unlocking operation has been performed, or the time measured by the timer T1 reaches the allowable operation time of the releasing operation permission means 8a, and the step If the determination result of a13 is true, in other words, if it is clear that an abnormal time is required for the password input operation, the CPU 8 sets the door lock means 13 to the unlocked state. Then, the alarm lamp 17 is turned off (step a17), the state storage flag F1 is initialized to 0 (step a1), and the initial standby state is restored.

  Further, when the timer T0 counts the allowable operation time and the determination result of step a7 becomes true, that is, the operation since the operation of the reception permission signal transmission switch 18 which is the first operation for the locking device 3 is performed. If the time is abnormally long, the CPU 8 assumes that the reception permission signal transmission switch 18 has been operated by mischief or the like and the state storage flag F1 is set to 1, and sets the door lock means 13 to the unlocked state. First, the alarm lamp 17 is turned off (step a17), the state storage flag F1 is initialized to 0 (step a1), and the initial standby state is restored.

As described above, the reception of the unlocking operation performed on the operation unit 15 of the locking device 3 is permitted by operating the reception permission signal transmission switch 18 of the locking device 3 installed in the door 2, And it has the authority which cancels | releases the state of the door lock in short, the mobile telephone 4 which has the telephone number beforehand memorize | stored in the memory | storage means 22a as a reception object of the unlocking operation performed with respect to the operation part 15 of the locking device 3 Only when a transmission operation is performed from the mobile phone 4 owned by the user, the door is actually unlocked by performing an appropriate unlocking operation on the operation unit 15 of the locking device 3. Limited to
That is, when a user who has the authority to release the door lock loses his / her own mobile phone 4 or is stolen, the third party who acquires the mobile phone 4 can operate the operation unit of the locking device 3. However, it is actually difficult for this third party to perform an appropriate unlocking operation using a numeric keypad, magnetic card, IC card, or the like. The risk that the door lock is inadvertently released due to loss or theft of 4 will be greatly reduced.
Further, when a user having the authority to release the door lock erroneously operates the mobile phone 4 owned by the user, a telephone number unique to the mobile phone 4 is transmitted to the facsimile apparatus 5 as identification information. However, unless the reception permission signal is transmitted to the facsimile apparatus 5 by the operation of the reception permission signal transmission switch 18 of the locking device 3 installed in the door 2, the identification information waiting means 25a of the facsimile apparatus 5 is an appropriate telephone number. Even if it exists, this is not accepted as a candidate for the unlocking operation acceptance permission signal, so that the operation unit 15 of the locking device 3 accepts an unlocking operation by a third party due to an inadvertent operation of the mobile phone 4 and the door lock is activated. The risk of being released is greatly reduced.

  As described above, when a user who has the authority to unlock the door erroneously operates the mobile phone 4 owned by the user, a telephone number unique to the mobile phone 4 is transmitted to the facsimile machine 5. As a possibility, there may be a case where a third party operated the reception permission signal transmission switch 18 of the locking device 3 to activate the identification information waiting means 25a of the facsimile device 5 before this erroneous operation was performed. In the present embodiment, the time when the identification information waiting unit 25a receives the telephone number as a candidate for the unlocking operation reception permission signal is set to the operation time of the reception permission signal transmission switch 18 (the reception permission signal of the reception permission signal reception unit 26a By restricting to T2 starting from the reception point), the unlocking operation acceptance start signal is based on the telephone number transmitted when the user having the authority to unlock the door erroneously operates the mobile phone 4 owned by the user. There is a danger that the transmission means 26b will inadvertently transmit the unlocking operation acceptance start signal, that is, the operation unit 15 is moved to the third state in a state where acceptance of the unlocking operation by the operation unit 15 of the locking device 3 is inadvertently permitted. It is possible to greatly reduce the risk of operation by a person.

  Furthermore, the release operation permission means 8a allows the lock release operation to the operation unit 15 within a preset time T1 after the lock release operation reception start signal receiving means 16b receives the lock release operation reception start signal. Therefore, it is possible to reduce the risk of a third party releasing the door lock by a random operation of the numeric keypad.

  FIG. 8 is a flowchart showing another embodiment of the process executed by the CPU 19 of the facsimile machine 5, and the lock release operation acceptance start signal transmission means 26 b of the facsimile machine 5 does not exceed the preset number m. This is different from the above-described embodiment in that the lock release operation acceptance start signal is transmitted only when the coincidence determination is performed for the preset number m (set value).

  Since the operation of the CPU 8 on the locking device 3 side is the same as that in the above-described embodiment, the description thereof will be omitted, and the processing operation of the CPU 19 in this embodiment will be briefly described with reference to FIG.

  The CPU 19 of the facsimile apparatus 5 initializes the value of the state storage flag F2 to 0 (step c1) and holds the value of the state storage flag F2 at 0 in the initialization process at the time of power-on, as in the case of the above-described embodiment. The reception permission signal is transmitted from the locking device 3 while repeatedly executing the determination process of whether or not the reception permission signal is transmitted from the locking device 3 (step c2). The reception permission signal transmitted from the locking device 3 is detected by the CPU 19 through the transmission / reception circuit 26 functioning as the reception permission signal receiving means 26a in the determination process of step c3.

  The CPU 19 that has detected the reception permission signal sets a permissible value to the timer T3 that defines the operating time of the identification information waiting means 25a after the reception permission signal receiving means 26a receives the reception permission signal, and starts measuring time. (Step c4), the fact that the operation of the identification information waiting means 25a has been started is set by setting the state storage flag F2 to 1 (Step c5), and the value of the counter C for counting the number of coincidence of the determination results Is initialized to 0 (step c6).

  Next, the CPU 19 determines whether or not the time count of the timer T3 has reached the allowable operation time (step c7). At this time, the time count of the timer T3 does not reach the allowable operation time, so the CPU 19 again Shifting to the determination process of step c2, it is determined whether or not the value of the state storage flag F2 is held at zero.

  Since 1 is already set in the state storage flag F2, the determination result in step c2 is false, the determination result in step c8 is true, and then the CPU 19 determines whether there is an incoming call from the mobile phone 4 ( Step c9) If there is no incoming call, the determination process of Step c2, Step c8, Step c9 and Step c7 is repeatedly executed on condition that the time count of the timer T3 has not reached the allowable operation time. Wait for incoming call.

  The user operates the cellular phone 4 using this waiting time and makes a call to the facsimile machine 5. However, in this embodiment, the lock release operation acceptance start signal transmission unit 26b of the facsimile apparatus 5 cannot be operated unless m transmission operations, which are a preset number of times, are continuously performed.

  The telephone number transmitted from the mobile phone 4 before the time measured by the timer T3 reaches the allowable operation time of the identification information standby unit 25a is the data transmission / reception circuit 25 that functions as the identification information standby unit 25a in the determination process of step c9. This is detected by the CPU 19 of the facsimile apparatus 5 via.

  Then, the CPU 19 that has received the telephone number that is a candidate for the unlocking operation acceptance permission signal once initializes the value of the telephone number search index i to 0 (step c10), and then increments the value of the index i by 1 again. (Step c11) Based on the current value of the telephone number search index i, the i-th telephone number stored in the non-volatile memory 22 functioning as the storage means 22a is read (Step c12). It is determined whether or not the telephone number received in the process of c9 matches (step c13). If not, the current value of the telephone number search index i is stored in the nonvolatile memory 22 It is determined whether or not the total number n has been reached (step c14).

  If the current value of the telephone number search index i has not reached the total number n of telephone numbers, the CPU 19 functioning as a determination unit in the unlocking operation acceptance start signal transmission unit 26b determines that the current value of the index i is the total number n of telephone numbers. If not, step c11 to step c14 are repeatedly executed in the same manner as described above.

  Here, when the determination result of step c13 is true, it means that the telephone number that matches the telephone number received in the process of step c9 is stored in the nonvolatile memory 22, so the CPU 19 Then, by incrementing the value of the counter C by 1, the number of coincidence determinations by the unlocking operation acceptance start signal transmitting unit 26b is updated and stored (step c15), and whether the number of coincidence determinations C has reached the set number m. It is determined whether or not (step c16).

  If the coincidence determination count C has not reached the set count m, the CPU 19 determines again whether or not the timer T3 has reached the allowable operating time of the identification information waiting means 25a (step c7), and the timer T3. If the measured time has not reached the allowable operation time of the identification information waiting means 25a, the process returns to step c2 again, and a new incoming call is waited within the allowable operation time of the identification information waiting means 25a (step c2). , Step c8, Step c9, Step c7) Each time an incoming call from the mobile phone 4 is confirmed (Step c9), it is determined whether or not a telephone number that matches the telephone number is stored in the nonvolatile memory 22 Only when the value is stored, the value of the counter C is incremented by 1 (step c10 to step c16).

  When it is confirmed in the determination process of step c16 that the number of coincidence determination C has reached the set number m during repeated execution of such processing, the CPU 19 sets the coincidence determination number C to be set. The timer T4 that defines the waiting time after reaching the value m is set to start timing (step c17), and the state storage flag F2 is set to 2 to thereby release the lock release operation acceptance start signal of the facsimile apparatus 5 It is stored that the coincidence determination of the number m set in advance by 26b has been performed (step c18).

  Next, the CPU 19 determines whether or not the time measured by the timer T3 has reached the allowable operation time (step c7). If the allowable time has not been reached, the CPU 19 proceeds to the determination process of step c2 again, and the state storage flag It is determined whether or not the value of F2 is held at 0.

  At this time, since the state storage flag F2 is set to 2, both the determination results of step c2 and step c8 are false, and the CPU 19 further determines whether or not the timer T4 has been timed (step c19) If the timing has not been completed, it is determined again whether or not there is an incoming call from the mobile phone 4 (step c20). If there is no incoming call, it is confirmed that the timers T3 and T4 have not reached the allowable operating time. As conditions, the determination process of step c2, step c8, step c19, step c20, and step c7 is repeatedly executed to check whether there is an incoming call from the mobile phone 4.

  If the determination result in step c19 is true and the completion of time measurement by the timer T4 is confirmed during the repeated execution of such processing, the unlocking operation acceptance start signal transmitting means 26b of the facsimile machine 5 is confirmed. The new number of incoming calls has not been confirmed even after the time T4 has elapsed since the predetermined number of times m has been determined in advance, that is, the transmission operation from the mobile phone 4 has exceeded the set number of times m. This means that it has been executed only m times, so the CPU 19 knows the number of transmission operations of the mobile phone 4 required to operate the unlocking operation acceptance start signal transmission means 26b. Appropriate user, that is, a user who has the authority to unlock the door is operating the mobile phone 4, and sends an unlock operation acceptance start signal After operating the transmission / reception circuit 26 constituting the main part of the stage 26b and transmitting the unlocking operation acceptance start signal to the locking device 3 (step c21), the value of the state storage flag F2 is initialized to 0 (step c1). Return to the initial standby state.

  On the other hand, if the determination result in step c20 is true, the lock release operation acceptance start signal transmission unit 26b performs m coincidence determinations, and then another incoming call is received within the time T4. That is, that is, a user who does not know the number of transmissions of the mobile phone 4 required for operating the unlocking operation acceptance start signal transmitting means 26b acquires the appropriate user's mobile phone 4 and outputs The CPU 19 that functions as the identification information waiting unit 25a stops the operation of recognizing the incoming telephone number as a candidate for the unlocking operation acceptance permission signal, The value of the storage flag F2 is initialized to 0 (step c1), and the initial standby state is restored. In this case, the unlock operation acceptance start signal is not transmitted.

  In addition, when the time measured by the timer T3 reaches the allowable operation time of the identification information waiting means 25a, in short, the determination result of step c7 becomes true without the determination result of step c19 and the determination result of step c20 being true. In such a case, a user who does not know the number of transmission operations of the mobile phone 4 required for operating the unlocking operation acceptance start signal transmitting means 26b acquires the appropriate user's mobile phone 4 and makes an output. The reception permission signal is transmitted due to a mischief with respect to the reception permission signal transmission switch 18 of the locking device 3 and the identification information waiting means 25a Since the operation may be started, the CPU 19 functioning as the identification information waiting unit 25a may receive an incoming telephone number as a sign of an unlock operation acceptance permission signal. Stop work recognized as the value of the condition storage flag F2 is initialized to 0 (step c1), it returns to the initial standby state. Also in this case, the unlock operation acceptance start signal is not transmitted.

  In this embodiment, the allowable time set in the timer T0 that regulates the allowable operation time after the operation of the reception permission signal transmission switch 18 is described above because it is necessary to receive the mobile phone 4 a plurality of times. In this embodiment, it is longer than the allowable operation time set in the timer T0. For the same reason, the allowable operation time set in the timer T3 that defines the operation time of the identification information standby unit 25a is longer than the allowable operation time set in the timer T2 in the above-described embodiment. . The set time of the timer T4 for determining the presence or absence of continuous incoming calls exceeding m times is set slightly longer than the time required for performing retransmission using the mobile phone 4. Has been.

  That is, the allowable operation time set in the timer T0 is longer than the allowable operation time of the release operation permission means 8a set in the timer T1, and is set in the timer T3 that defines the operation time of the identification information waiting means 25a. The allowable operation time is shorter than the allowable operation time set in the timer T1, and has a relationship of T3 <T1 <T0. The set time of the timer T3 sets the mobile phone 4 to m for transmission of a telephone number as identification information. That is, it is set to be slightly longer than a value obtained by adding the set time of the timer T4 to the time required to perform the rotation operation.

In the embodiment to which the processing of FIG. 8 is applied, even when a telephone number serving as identification information is transmitted from an appropriate mobile phone 4, the facsimile machine 5 is set a predetermined number of times (m times). Since the lock release operation acceptance start signal is not transmitted unless it is received by the identification information waiting means 25a, the third party who has acquired the mobile phone 4 of the user who has the authority to release the door lock operates the operation unit 15 of the locking device 3. The possibility of attempting a lock release operation can be greatly reduced, and as a result, the risk of the door lock being released is further reduced.
In addition, when the transmission operation of the mobile phone 4 is performed more times than the preset number m, this is detected and the transmission of the unlocking operation acceptance start signal is prohibited. The problem that the lock release operation acceptance start signal is transmitted from the facsimile apparatus 5 in the 4th transmission operation is also prevented.

In the above embodiment, a mobile phone is used as a portable mobile communication terminal and a facsimile device is used as an indoor communication device. However, as a portable mobile communication terminal, other than a mobile phone can be used. PDA (Personal
Digital Assistance) and PHS (Personal
Handyphone System) or the like can be used, and a personal computer or the like can be used in addition to a facsimile machine as an indoor information communication device. Furthermore, it is also possible to use a fixed telephone with the functions of the storage means 22a, the reception permission signal receiving means 26a, the identification information waiting means 25a, and the lock release operation acceptance start signal transmitting means 26b. .
In any case, countermeasures against crime prevention can be strengthened by managing whether or not the unlocking operation to the operation unit 15 of the locking device 3 can be managed from the room by using an indoor communication device.

  In addition, as identification information, it is most convenient to use a telephone number provided by a caller ID notification service (number display), and it is advantageous in that no actual call charge is charged. Even if an e-mail address or e-mail header identification information (prepared in advance and registered in the mobile phone or storage means 22a) is sent from the mobile phone to an information communication device such as a facsimile machine. A processing operation similar to that described above can be applied.
