Description

  The present invention includes a detection unit that detects an abnormality in the security target area, an alarm device that issues an alarm when the detection unit detects an abnormality, and a support center that supports a user of the alarm device. Further, the present invention relates to a security system provided with a personal identification number receiving means for receiving a personal identification number and an alarm stopping means for stopping an alarm when the personal identification number is received by the personal identification number receiving means.

  Conventionally, in order to prevent an intruder from easily stopping an alarm, this type of security system is configured so that the alarm cannot be stopped unless a predetermined password is input. However, in such a configuration, when the user of the alarm device forgets the personal identification number, the alarm cannot be stopped and there is a possibility that the neighborhood will be disturbed by continuing to sound for a long time.

  In order to cope with such a problem, Patent Document 1 discloses that a warning code (so-called master code) is stored in advance in the alarm device separately from a normal password, and a master code is used as necessary. The structure which can stop the alarm of an alarm device is disclosed. However, in such a configuration, the master code cannot be transmitted to the user in advance to prevent the master code from leaking. For this reason, it was necessary for the business operator to go to the place where the alarm device was provided and stop the alarm using the master code. In this case, there is a problem that it takes time until the alarm is stopped, and the neighborhood is troubled during that time.

  In response to such a problem, in Patent Document 1, when using an alarm device that is communicably connected to a center provided on the operator side, the operator sets the master code of the alarm device via a communication line. It is disclosed to change appropriately.

JP 2005-216051 A

  However, the technology disclosed in the above-described prior art cannot be employed in an alarm device that is not connected to a communication line and is not configured to be communicable with a business center. In other words, in the alarm device that is not configured to be able to communicate with the center of the operator side, if the user forgets the normal password, it takes time to stop the alarm, and in the meantime, the neighborhood is inconvenienced. There are challenges.

  The present invention has been made in view of the above-mentioned problems, and its purpose is to promptly by a user when a user forgets a normal password in an alarm device that is not configured to communicate with the center. It is to provide a security system capable of stopping an alarm.

  The security system according to the present invention is characterized by detection means for detecting an abnormality in the security target area, an alarm device for issuing an alarm when the detection means detects an abnormality, and support for a user of the alarm device A security system comprising: a support center that performs a security code, and a security code receiving unit that accepts a security code, and an alarm stop unit that stops a warning when the security code is received by the security code reception unit, The alarm device has a key issuing operation accepting unit for accepting a code number key issuing operation for requesting issuance of a predetermined code number key, and the key issuing operation accepting unit has accepted the predetermined code number key issuing operation. A key generating means for generating a key at the time, a key output means for outputting the key generated by the key generating means to the outside, and a password from the key by a specific algorithm A device-side password generating unit that generates a password corresponding to the key generated by the key-generating unit, and receiving the specific password generated by the device-side password generating unit by the password-receiving unit. The alarm stop means is configured to stop the alarm, and the support center generates a password that is the same as the key input means for inputting a key, and the apparatus-side password generation means provided in the alarm device. Center-side password generation means for generating a specific password from the key by an algorithm, and the center-side password generation means generates a specific password for the key input to the key input means. , In the point to output.

According to the above characteristic configuration, the alarm device user can issue a password number key issuing operation, and the alarm device alarm can be stopped by the device-side code number generation means corresponding to the key in the alarm device. A new password is newly generated and can be used. In addition, since the security code corresponding to the security code key can be generated at the support center, the user of the alarm device notifies the support center of the security code key acquired by the security code key issuing operation. You can get a PIN that can stop the alarm. Then, when the user inputs the personal identification number transmitted from the support center to the alarm device, the alarm device generates the personal identification number previously generated corresponding to the input personal identification number and the key. Compare the number, confirm the match, and stop the alarm.
With such a configuration, in an alarm device that is not configured to be communicable with the support center, it is possible to provide a security system that can quickly stop an alarm by the user when the user forgets the normal password. Moreover, since it is necessary to once interact with the support center in order to issue the password of the alarm device, it is possible to prevent the alarm from being easily stopped by an intruder.

  A further feature is that the password number key issuing operation is a long press operation.

  According to the above characteristic configuration, since the password issuing operation takes a long time, it is possible to further prevent the intruder from stopping the alarm more easily.

  Another feature is that the alarm device includes a generation number storage unit that stores the number of times the key generation unit has generated the key, and the key generation unit corresponds to the number of times stored in the generation number storage unit. And is configured to generate different keys.

  According to the above characteristic configuration, each time a user of the alarm device generates a password key, the password that can be used by the alarm device is different. For this reason, it can suppress that the alarm of an alarm device stops by the intruder etc., for example because the PIN number once made available leaks. That is, in the alarm device that is not configured to be communicable with the support center, it is possible to provide a security system that can quickly stop the alarm by the user when the user forgets the normal password.

  Further, another feature is that the alarm device includes a time limit setting unit that sets a validity period of the personal identification number when the personal identification number is generated by the device-side personal identification number generation unit, and the alarm stop unit includes the time limit The alarm is stopped only when the personal identification number for which the validity period is set is received by the personal identification number receiving means within the validity period set by the setting means.

  According to the above characteristic configuration, when the user of the alarm device generates the code number key, an expiration date is set for the code number that can be used by the alarm device. That is, a so-called one-time password can be set in the alarm device. For this reason, in the alarm device that is not configured to be communicable with the support center, it is possible to provide a security system that can stop the alarm promptly by the user when the user forgets the normal password.

  The features of another security system according to the present invention include detection means for detecting an abnormality in the security target area, an alarm device that issues an alarm when the detection means detects an abnormality, and a user of the alarm device A security system comprising a support center that provides support, and an alarm device that includes a PIN number receiving means for inputting a PIN number and an alarm stopping means for stopping an alarm when the PIN number is received by the PIN number receiving means. The alarm device is a value unique to the alarm device, and includes a patch on which a device unique value for issuing a password is described, and a device for generating a password using a specific algorithm using the device unique value A side code number generating means, corresponding to the device specific value, and when the specific code number generated by the apparatus side code number generating means is received by the code number receiving means, An alarm stop means is configured to stop the alarm, and the support center specifies a specific value input means for inputting a device specific value, and a specific code number generation algorithm that is the same as that of the device-side password generation means. A center-side password generating means for generating a password, and the center-side password generating means generates and outputs a specific password corresponding to the device unique value input to the unique value input means. is there.

According to the above-described characteristic configuration, the “device unique value” described in the sticker is used as a key in the sequence of “key number key issuing operation → key generation → external output” described above. The movement after the user knows the “apparatus unique value” is the same as the previous example.
As a result, even in this configuration, according to the above-described characteristic configuration, in the alarm device that is not configured to be able to communicate with the support center, when the user forgets the normal password, the user immediately stops the alarm A possible security system can be provided. Moreover, since it is necessary to once interact with the support center in order to issue the password of the alarm device, it is possible to prevent the alarm from being easily stopped by an intruder. Furthermore, with this configuration, it is only necessary to add a sticker to the existing alarm device as hardware, and if the user forgets the normal password, the user can quickly stop the alarm. A security system can be provided inexpensively using existing alarm devices.

  Furthermore, another feature is that the alarm device stores the number of times the device-side password generation unit has generated a password, and the number of times stored in the generation number storage by a predetermined operation. A number-of-times display means that can be displayed externally, wherein the device-side password generation means is configured to generate a different password according to the number of times of input, and the number of times stored in the number-of-generations storage means The support center is configured to be input to the device-side password generation unit, and the support center includes a number-of-times input unit that inputs a predetermined number of times, and the number of times input to the number-of-times input unit includes the support center. The input to the center-side password generation means.

  According to the above characteristic configuration, each time the user of the alarm device performs a predetermined operation, the personal identification number that can be used by the alarm device is different. For this reason, it can suppress that the alarm of an alarm device stops by the intruder etc., for example because the PIN number once made available leaks. In addition, since the number of times that a predetermined operation has been performed is communicated to the support center, the number of times that the security code is generated on the alarm device side and the number of times the security code is generated on the support center side can always be matched. Therefore, it is possible to prevent a password that can be used from being generated by the support center. Specifically, for example, when the user of the alarm device performs a predetermined operation, but then remembers the normal password and does not use the password generated in the alarm device, the predetermined operation is performed next time. It is possible to prevent the number of times that a predetermined operation has been performed in the past between the alarm device and the support center from being different.

As shown in FIG. 1, the security system 1 includes a detection unit 2 that detects an abnormality in a predetermined security target region R, an alarm device 3 that issues an alarm when the detection unit 2 detects an abnormality, A support center 4 for supporting the user U of the alarm device 3 is provided.

  As the detection means 2, an infrared sensor, a passive sensor, a magnet sensor that detects opening / closing of a window or a door, an audio sensor that detects a breaking sound of a window glass, or the like can be used. The detection means 2 is configured to be communicable with the alarm device 3 and configured to transmit a signal indicating that an abnormality has been detected to the alarm device 3 when an abnormality is detected.

  The alarm device 3 is configured to issue an alarm to the surroundings when an abnormality is detected in the security target region R. Specifically, it is composed of a microcomputer provided with an arithmetic unit and a storage area, and is configured to be able to receive a signal from the detection means 2. The alarm device 3 includes a speaker and is configured to issue an alarm.

  In the present embodiment, the alarm device 3 is not configured to be communicable with the outside such as the support center 4. That is, the alarm device 3 is configured to be able to communicate only with the detection means 2 and is not connected to an external communication line.

  As shown in FIG. 2, the alarm device 3 includes a personal identification number receiving unit 31 for accepting an input of a personal identification number by the user U. Specifically, the alarm device 3 includes ten push buttons corresponding to numbers from 0 to 9 as the personal identification number receiving means 31, and is configured so that the user U can input the personal identification number. In the present embodiment, a multi-digit number is used as the password.

  Further, the alarm device 3 is in a state where an alarm is issued, and when the password is received by the password receiving means 31 and the password is correct (a password generated separately in the alarm device 3). Alarm stop means 32 for stopping the alarm is provided. In the present embodiment, the alarm device 3 is used when the user U forgets the personal identification number A in addition to the personal identification number A set in advance as the personal identification number for stopping the alarm by the alarm stopping means 32. A password X for use in an emergency is automatically generated according to a predetermined sequence. The alarm stop unit 32 is configured to stop the alarm when the code number A or the code number X is received from the code number receiving unit 31. When a password other than the password A or the password X is accepted, the alarm is not stopped. However, the password issuing operation for a personal identification number, which will be described later, is configured to be known by the user.

  Here, the personal identification number A is a personal identification number used at normal times, and is usually informed to the user U when the alarm device 3 is installed or set by the user U. On the other hand, the personal identification number X is a personal identification number used in an emergency, and is usually not notified to the user U when the alarm device 3 is installed.

  The support center 4 is configured to provide a personal identification number X to the user U of the alarm device 3 through a telephone line or an internet line. Specifically, the support center 4 receives the inquiry q of the personal identification number X for stopping the alarm from the user U, for example, when the user U forgets the personal identification number A, and uses it in the form of answering it. The personal identification number X is transmitted to the person U.

  The security system 1 according to the present invention is characterized by a method of handling a password X in an emergency. Below, the structure and usage method of the security system 1 for safely exchanging the PIN number X will be described.

[First Embodiment]
1. Configuration of security system 1-1. Configuration of Alarm Device As shown in FIG. 2, the alarm device 3 includes a key issuing operation accepting unit 33 that accepts a code number key issuing operation i for requesting the issuance of a predetermined code number key k. The key issuing operation accepting means 33 is configured to accept the code number key issuing operation i only during alarming. Here, the code number key k means a specific numerical value used when the code number X is generated. Specifically, the key issuing operation accepting unit 33 is an emergency push button, and the code number key issuing operation i corresponds to a long press operation on the emergency push button. Specifically, in order to make the operation by an intruder difficult, it is preferable to perform a long press operation of several tens of seconds to several minutes.

  The alarm device 3 includes key generation means 34 that generates a code number key k. The key generation means 34 is configured to generate a personal identification number key k when the key issuing operation reception means 33 accepts a predetermined personal identification number key issuing operation i.

  In the present embodiment, the alarm device 3 includes a generation number storage unit 35 that stores the number n of times the key number k is generated by the key generation unit 34, and the key generation unit 34 stores the generation number storage unit 35. A different code number key k is generated according to the number of times n. Specifically, when the key generation unit 34 generates the code number key k, the generation number storage unit 35 is notified that the code number key k is to be generated. The number-of-generations storage means 35 counts the number of times the notification has been received, and stores the number of integrations counted so far as the number n of times the key has been generated.

  Further, upon receiving the notification from the key generation unit 34, the generation number storage unit 35 counts the number of times the notification is received and then sends the stored number n to the key generation unit 34. After that, the key generation means 34 generates a password number key k using the received number n. In the present embodiment, the number n of times the key is generated is used as the personal identification number key k.

  The alarm device 3 includes a key output unit 39 that outputs the personal identification number key k generated by the key generation unit 34 to the outside so as to convey it to the user U. As the key output means 39, an output means by sound such as a speaker or an output means by light such as an LED can be used. Specifically, for example, when using sound output means, it is preferable to output a “beep” sound for the value of the code number key k. (For example, if the code number key k is “3”, a beep sound is output). For example, when using an output means using light, it is preferable that the light is blinked by the value of the code number key k. In this way, it is possible to notify the user U of the code number key k generated by the key generation means 34.

  The alarm device 3 includes device-side password generation means 36 for generating a password X with a specific algorithm f (k) from the input password key k. That is, the alarm device 3 is configured such that the personal identification number key k generated by the key generation unit 34 is output by the key output unit 39 and also input to the device side personal identification number generation unit 36. The device-side personal identification number generation means 36 generates a personal identification number X based on the input personal identification number key k. As the algorithm f (k) used at this time, it is preferable to employ an algorithm in which the correlation between the number n of key generations and the personal identification number X is difficult to guess, but a simple algorithm may be used. . Specifically, for example, as the algorithm f (k), a simple mechanism of adding the value of the code number key k to a predetermined value may be used.

  Further, the alarm device 3 includes a time limit setting unit 37 that sets an expiration date lim of the personal identification number X when the personal identification number X is generated by the device-side personal identification number generation unit 36. Here, the expiration date “lim” means a period during which the alarm of the alarm device 3 can be stopped by the password X. Specifically, for example, the expiration date setting means 37 indicates the expiration date lim, a predetermined period after the device-side password generation unit 36 generates the password X, or until the alarm of the alarm device 3 is stopped. Can be set.

  The alarm device 3 corresponds to the personal identification number key k generated by the key generation unit 34, and when the specific personal identification number X generated by the device side personal identification number generation unit 36 is received by the personal identification number reception unit 31, The alarm stop means 32 is configured to stop the alarm. Specifically, after the password number X is generated by the device-side password number generation means 36, when the password number Y is input to the password number receiving means 31 by the user U, the password number check means 38 determines the password number X. It is determined whether or not the input password Y is the same. If the input password Y is the same as the password X, the password check means 38 sends a command to the alarm stop means 32 to stop the alarm of the alarm device 3.

  In the present embodiment, the alarm stop unit 32 only receives the password X in which the expiration date lim is set by the password receiving unit 31 within the expiration date lim set by the time limit setting unit 37. Configured to stop the alarm. Specifically, when the password number Y input to the password number receiving means 31 is input, it is determined whether the password number Y and the password number X input by the password number check means 38 are the same. If they are the same, the alarm is stopped by the alarm stop means 32. On the other hand, if the entered password number Y and the password number X are different, the alarm is not stopped.

  With the above configuration, when the user U of the alarm device 3 forgets the personal identification number A, the personal identification number key issuance operation i is performed to obtain the personal identification number key k, and then is exchanged for the personal identification number key k. The alarm can be stopped by acquiring the code number X. A flow in which the user U obtains the personal identification number X in exchange for the personal identification number key k will be described later.

1-2. Configuration of Support Center FIG. 3 shows a support terminal 5 provided in the support center 4. The support terminal 5 is used as a pair with the alarm device 3 in the present invention. The support terminal 5 of the support center 4 includes a key input unit 51 for inputting a code number key k and a code number using the same code number generation algorithm f (k) as the device side code number generating unit 36 provided in the alarm device 3. And a center side code number generating means 52 for generating a specific code number X from the key k.

  Specifically, the support terminal 5 is composed of a microcomputer provided with an arithmetic device and a storage area. As the key input means 51, for example, a keyboard can be used.

  Further, the personal identification number generation means 52 generates a specific personal identification number X for the personal identification number key k input to the key input means 51 and outputs it to the outside by the personal identification number output means 53. Yes. Specifically, for example, a display can be used as the password number output means 53. With such a configuration, the user of the support terminal 5 can obtain the personal identification number X corresponding to the specific personal identification number key k.

2. Operation and Usage Method of Security System A usage method of the security system 1 (the alarm device 3 and the support terminal 5) according to the present embodiment will be described with reference to FIG. In the following, when the alarm device 3 issues an alarm, in the situation where the user U has forgotten the password A for stopping the alarm, the flow until the password X is obtained from the support center 4 and the alarm is stopped. Will be explained.

  The user U of the alarm device 3 first performs a code number key issuing operation i. In response to the code number key issuing operation i, the alarm device 3 generates the code number key k by the key generation means 34 and outputs the code number key k by the key output means 39. The user U informs the support center 4 of the personal identification number key k output to the key output means 39 by the personal identification number key issuing operation i. Here, the transmission of the password key k from the user U to the window C of the support center 4 can be performed verbally using a telephone line or by e-mail using an Internet line (the latter example is shown in FIG. 1).

  The contact C of the support center 4 inputs the code number key k transmitted from the user U into the key input means 51 of the support terminal 5. The support terminal 5 generates the code number X by the center-side code number generation means 52 and outputs it to the code number output means 53. The window C informs the user U of the alarm device 3 of the password number X output to the password number output means 53.

  The user U of the alarm device 3 who has acquired the password number X from the window C inputs the password number X to the password number receiving means 31 and stops the alarm by the alarm stop means 32. As described above, in a situation where the user U has forgotten the personal identification number A, the user U can acquire the personal identification number X from the support center 4 and stop the alarm.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to the drawings. In the second embodiment, the configurations of the alarm device 3 and the support center 4 are different, and in particular, the algorithm f (SN) for generating the password X is different from that in the first embodiment. In the following description, the same parts as those in the first embodiment are omitted as appropriate.

1. Configuration of security system 1-1. Configuration of Alarm Device As shown in FIG. 5, the alarm device 3 includes a patch 61 that is a value unique to the alarm device 3 and has a device unique value SN for issuing a personal identification number. Specifically, the alarm device 3 includes, for example, a sticker on which a QR code (registered trademark) including a device unique value SN or a barcode is printed as the sticking object 61. In the present embodiment, the device specific value SN is a numerical value of a plurality of digits.

  In the present embodiment, the alarm device 3 includes a generation number storage unit 35 that stores the number n of generations of the password by the device-side password generation unit 62. A number display means 63 capable of displaying the number n stored in the generation number storage means 35 by a predetermined number display operation c to the outside. Here, the number display operation c can be, for example, an operation of pressing and holding a predetermined button.

  Specifically, when the user U performs the number-of-times display operation c on the number-of-times display operation accepting unit 64, the alarm device 3 notifies the generation number storage unit 35 to that effect. The generation number storage means 35 stores the number of times the notification is received as the number n of generation of the password. Thereafter, the number n stored in the generation number storage unit 35 is notified to the number display unit 63, and the number display unit 63 displays the number n outside. Here, as the number-of-times display means 63, for example, an LED can be used. In this case, the number display means 63 can display the number n outside by a method such as blinking the number n.

  Further, the alarm device 3 includes a device-side password generation unit 62 that generates a password X with a specific algorithm f (SN) using the device unique value SN. In the present embodiment, the device-side password generation unit 62 is configured to generate a different password X in accordance with the input number n. Specifically, the device-side password generation unit 62 inputs the device-specific value SN stored in advance in the alarm device 3 and the number of times stored in the generation number storage unit 35 to the device-side password generation unit 62. It is configured as follows. With this configuration, the device-side password generation unit 62 generates the password number X based on the device unique value SN and the number of times n. At this time, as f (SN), it is preferable to employ the one whose correlation between the number n and the personal identification number X is difficult to guess, but a simple algorithm may be used. Specifically, for example, as the algorithm f (SN), a simple mechanism in which the value of the device specific value SN and the number n are added to a predetermined value may be used.

  Further, the alarm device 3 includes a personal identification number receiving means 31, and when the personal identification number X corresponding to the apparatus unique value SN and generated by the apparatus-side personal identification number generation means 62 is received by the personal identification number reception means 31, the alarm is stopped. The means 32 is configured to stop the alarm. Specifically, after the password number X is generated by the device-side password generation means 62, when the password U is input to the password number receiving means 31 by the user U, the password number check means 38 determines the password number X. It is determined whether or not the input password Y is the same. If the input password Y is the same as the password X, the password check means 38 sends a command to the alarm stop means 32 to stop the alarm of the alarm device 3, and the alarm stop means 32 Stop the alarm.

1-2. Configuration of Support Center FIG. 6 shows the configuration of the support terminal 5 provided in the support center 4. The support terminal 5 of the support center 4 includes a specific password input means 71 for inputting the device unique value SN, and a specific password X from the device unique value SN using the same password generation algorithm f (SN) as the device-side password generating means 62. And a center-side password generation means 72 for generating the password. Further, in the present embodiment, the support terminal 5 includes a number-of-times input unit 73 that inputs a predetermined number of times n. As the eigenvalue input means 71 and the number input means 73, for example, a keyboard can be used.

  In the support terminal 5, in response to the device unique value SN input to the unique value input means 71, the center-side personal identification number generation means 72 generates a specific personal identification number X. In the present embodiment, in addition to the device specific value SN, the number n inputted to the number input means 73 is inputted to the center side code number generating means 72 provided in the support center. The center side code number generating unit 72 generates the code number X based on the device unique value SN and the number of times n, similarly to the device side code number generating unit 62.

  Thereafter, the support terminal 5 externally outputs the personal identification number X generated by the center personal identification number generation means 72 by the personal identification number output means 53.

2. Operation and Usage Method of Security System A usage method of the security system 1 according to the present embodiment will be described with reference to FIG. First, the user U of the alarm device 3 transmits the device specific value SN described in the paste 61 to the window C of the support center 4. At this time, the user U may obtain the device unique value SN by reading the device unique value SN described in the patch 61 using, for example, a bar code reader provided in a mobile phone or the like. In the present embodiment, when the device specific value SN is transmitted to the window C, the user U of the alarm device 3 also transmits the number n displayed by the number display means 63. That is, the number display operation c is performed, and the number n displayed by the number display means 63 is acquired. The transmission of the device specific value SN and the number of times n can be performed verbally using a telephone line or by mail using an Internet line.

Next, the window C of the support center 4 inputs the device unique value SN and the number of times n transmitted from the user U to the unique value input means 71 of the support terminal 5. In the present embodiment, the support center window C inputs the transmitted device unique value SN to the unique value input means 71 and inputs the transmitted number of times n to the number input means 73. The support terminal 5 generates the password X by the center-side password generation means 72 and displays it on the password output means 53. The window C informs the user U of the alarm device 3 of the password number X output to the password number output means 53.

  The user U of the alarm device 3 who has acquired the personal identification number X from the window C inputs the personal identification number X into the personal identification number receiving means 31 and the alarm stopping means 32 stops the alarm. As described above, in a situation where the user U has forgotten the personal identification number A, the user U can acquire the personal identification number X from the support center 4 and stop the alarm.
