Security system and security method

Abstract

To efficiently set and release an operation mode including a home presence mode.SOLUTION: When an inhabitant enters a residence through a main entrance, an authentication device 20 acquires a terminal ID of a portable terminal 30 (S1). The authentication device 20 uses this terminal ID to authenticate the portable terminal 30 and sends a release mode setting request to a control device 10 (S2). When an operation mode is a "security mode", the control device 10 sets the operation mode to a "release mode" (S3) and sends a message display request to the authentication device 20 (S4). When receiving the message display request, the authentication device 20 displays the release of the security mode (S5). When the operation mode is a "home presence mode", the control device 10 continues the "home presence mode" (S6) and sends a message display request to the authentication device 20 (S7). When receiving the message display request, the authentication device 20 displays the continuation of the home presence mode (S8).SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] The present invention relates to a security system and a security method that can efficiently set and release operation modes, including a stay-at-home mode. [Background technology]

[0002] Conventionally, in a security system installed in a house, dwelling unit or office (hereinafter referred to as a "house, etc.") to be monitored, when the operation mode is set to security mode and a person is detected entering the house, if the person's biometric information or identification information such as a card carried by the person has been registered in advance, a technology is known in which the system determines that the person, i.e., a legitimate resident, has returned to the house, etc., and automatically sets the operation mode to deactivation mode.

[0003] For example, Patent Document 1 discloses a technology in which a security control device cancels the alert mode of a security device (security sensor) when an outside home passage detection device detects a person entering a house or the like and an identification code received by an interrogator is compared with and matches a pre-registered identification code. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2006-350862 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the above-mentioned Patent Document 1 only cancels the security mode of the security device, that is, it only controls the switching of the operation mode of the security system from a security mode that provides security when no resident is present in the house to a cancellation mode that does not provide security, and does not take into consideration an at-home mode that provides security even when a resident is present in the house. Therefore, if the operation mode of the security system has been set to the at-home mode by a resident who has already returned home, the at-home mode will be cancelled and set to the cancellation mode when another resident returns home. As a result, there is a problem in that the operation mode of the security system must be set to the at-home mode again.

[0006] The present invention has been made to solve the problems (issues) of the prior art described above, and aims to provide a security system and security method that can efficiently set and cancel operating modes, including home mode. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention is a security system for guarding a monitored object, comprising an authentication means for authenticating whether a person positioned at an entrance / exit of the monitored object has the authority to change the operation mode of the security system, and a control means for controlling the operation mode to be maintained as the home mode when the authentication means authenticates that the person has the authority to change the operation mode of the security system and the current operation mode is a home mode.

[0008] In addition, in the above invention, the present invention further includes a reading means installed at the entrance / exit of the monitored object, and a storage means for storing registered identification information registered as a portable terminal carried by a legitimate user of the monitored object, and the authentication means compares the identification information of the portable terminal read by the reading means with the registered identification information stored in the storage means, and authenticates whether the person has the authority to change the operating mode of the security system of the monitored object.

[0009] In addition, the present invention is characterized in that, in the above invention, it has a detection means for detecting whether or not a person is present at an entrance / exit of the monitored object, and when the person is detected by the detection means, the identification information is read by the reading means.

[0010] In addition, the present invention is characterized in that, in the above invention, the authentication means authenticates that the person has the authority to change the operation mode of the security system and when the current operation mode is the home mode, the invention further includes a second notification means for notifying that the current operation mode is the home mode.

[0011] In addition, in the above invention, the control means controls the operation mode to a release mode when the person is authenticated by the authentication means as a person with authority to change the operation mode of the security system and the current operation mode is a security mode.

[0012] The present invention also provides a security method executed in a security system that provides security for a monitored object, comprising an authentication step of authenticating whether a person positioned at an entrance / exit of the monitored object has the authority to change the operation mode of the security system, and a control step of controlling the operation mode to be maintained as the home mode when the person is authenticated as a person with the authority to change the operation mode of the security system by the authentication step and the current operation mode is a home mode. Effect of the Invention

[0013] According to the present invention, it is possible for a resident to efficiently set and cancel operation modes, including at-home mode, while realizing the convenience of being able to set the security system's operation mode to the deactivation mode without performing any operations when returning home.

[0015] The security system and the security method according to the present invention will be described in detail below with reference to the drawings. Here, the case where a house is the object of monitoring and the security system is installed in the house will be described as an example, but the present invention is not limited to this and may be installed in an office or the like. The security system according to the present invention has at least "security mode", "release mode" and "home mode" as operation modes. The "security mode" is an operation mode set when no resident is present in the house, etc., in which an intrusion detection sensor installed in the house detects a person, and if it is determined that the detected person is an intruder, an alarm is sent to the resident's mobile terminal or a pre-set notification destination such as a monitoring center of a security company (hereinafter referred to as "monitoring center of the security company, etc.") to notify the occurrence of an abnormality. The "release mode" is an operation mode set when a resident is present in the house, etc., in which even if the intrusion monitoring sensor detects a person, it is not determined that an abnormality occurs and an alarm is not sent. The "home mode" is an operation mode set when a resident is present in the house, etc., like the release mode, but in which an intrusion monitoring sensor installed in an entry point from the outside such as a window or door or in an area designated by the resident detects a person, and if it is determined that the detected person is an intruder, an alarm is sent to a monitoring center of a security company, etc. to notify the occurrence of an abnormality. Each operation mode can be set by operating the control device 10, or can be set using the authentication device 20.

[0016] <Security system overview> Fig. 1 is an explanatory diagram for explaining an overview of the security system. As shown in Fig. 1, when the authentication device 20 detects that a resident carrying a mobile terminal 30 has entered the house through the front door, the authentication device 20 acquires the terminal ID of the mobile terminal 30 (S1). The authentication device 20 authenticates the mobile terminal 30 using this terminal ID and a terminal ID of the mobile terminal 30 carried by the resident that has been registered in advance (corresponding to "registered identification information" described in the claims), and transmits a release mode setting request to the control device 10 (S2).

[0017] When the control device 10 receives the release mode setting request, if the operation mode is "security mode", it sets the operation mode to "release mode" (S3) and transmits a message output instruction to the authentication device 20 to notify the resident who has returned home that the operation mode has been set to the release mode (S4). When the authentication device 20 receives the message output instruction, it notifies the resident that the operation mode has been set to the release mode by text, voice, etc. (S5). For example, it displays "security has been released".

[0018] If the operation mode is "home mode" when the control device 10 receives the cancellation mode setting request, it does not change the operation mode and continues the "home mode" (S6), and transmits a message output instruction to the authentication device 20 to notify the resident who has returned home that the current operation mode is set to home mode (S7). When the authentication device 20 receives the message output instruction, it outputs to the resident who has returned home by text, voice, or the like, that the current operation mode is set to home mode. For example, it displays "Home security is on duty."

[0019] If the operation mode is "release mode" when the control device 10 receives the release mode setting request, it notifies the authentication device 20 that the operation mode is already "release mode" (S9). When the authentication device 20 receives the notification that the operation mode is "release mode", it displays the detected terminal ID information and the security button (S10). When the displayed security button is operated (S11), the authentication device 20 transmits a security mode setting request to the control device 10 (S12). When the control device receives the security mode setting request, it sets the operation mode to "security mode" after a predetermined time (S13).

[0020] In this way, the security system of the present invention is configured so that when a pre-registered mobile terminal is authenticated, a new operating mode is set or the current operating mode is continued depending on the operating mode setting status. This prevents the home mode from being cancelled when the resident returns home, and enables the setting and cancellation of operating modes including the home mode to be performed efficiently.

[0021] <Configuration of the control device 10> Next, a description will be given of the configuration of the control device 10. Fig. 2 is a functional block diagram showing the configuration of the control device 10 shown in Fig. 1. As shown in Fig. 2, the control device 10 has an input unit 11, a timer 12, a transmission / reception unit 17, a storage unit 18, and a control unit 19.

[0022] The input unit 11 is an input device including a touch panel display, buttons, a microphone, and the like, and outputs to the control unit 19 signals corresponding to operations by an operator, voice input, and the like.

[0023] The timer 12 is a device that measures time in response to instructions from the control unit 19, and includes an entrance timer, an exit timer, and a delay timer. The entrance timer measures the time to wait before sending an alarm when, for example, a sensor installed on the front door detects the door being opened. The exit timer measures the time to ignore detection signals from sensors whose detection areas include the path from the installation position of the control device 10 to an entrance such as the front door, after the security mode setting operation. The delay timer measures the time to wait before sending an alarm when a detection signal is input from a sensor at the monitored object during the at-home mode.

[0024] The transmitting / receiving unit 17 is an interface unit for transmitting and receiving signals between the sensor and the authentication device 20, and for transmitting an alarm to a monitoring center of a security company or the like. When a signal is input from the control unit 19, the transmitting / receiving unit 17 transmits the signal to the authentication device 20, and when a detection signal from the sensor or a signal from the authentication device 20 is received, the transmitting / receiving unit 17 outputs the received signal to the control unit 19. Furthermore, when an alarm is input from the control unit 19, the transmitting / receiving unit 17 transmits the alarm to a monitoring center of a security company or the like.

[0025] The storage unit 18 is a storage device formed of a non-volatile memory or a hard disk drive, and stores sensor data 18a, monitored sensor data 18b, and operation mode data 18c.

[0026] The sensor data 18a is data indicating information about sensors installed in the home to be monitored. The monitored sensor data 18b is data indicating sensors to be monitored during the at-home mode. The operation mode data 18c is data indicating the setting status of the operation mode.

[0027] The control unit 19 is a control unit that performs overall control of the control device 10, and includes a monitoring target setting unit 19a, a detection signal processing unit 19b, an operation mode control unit 19c, and an alarm transmission unit 19d. In practice, these programs are loaded into a CPU (Central Processing Unit) and executed, causing the monitoring target setting unit 19a, the detection signal processing unit 19b, the operation mode control unit 19c, and the alarm transmission unit 19d to execute their respective corresponding processes.

[0028] The monitoring target setting unit 19a is a processing unit that manages the monitoring target sensor data 18b. When information on a sensor to be monitored is input from the input unit 11 in a home mode setting operation by a resident, the monitoring target setting unit 19a stores the information on the sensor in the monitoring target sensor data 18b and updates it.

[0029] The detection signal processing unit 19b is a processing unit that performs a predetermined process based on the detection signal received from the sensor. When the detection signal processing unit 19b receives a detection signal from the sensor, it uses the detection signal and the sensor data 18a stored in the memory unit 18 to determine the type and installation location of the sensor. When the detection signal processing unit 19b determines that the sensor that transmitted the detection signal is a sensor that detects fire or gas leakage, it passes an alarm transmission instruction to the alarm transmission unit 19d. When the detection signal processing unit 19b determines that the sensor that transmitted the detection signal is a sensor that detects intrusion, it checks the current operation mode stored in the operation mode data 18c. When the current operation mode is "security mode" or "home mode", the detection signal processing unit 19b determines whether the sensor that transmitted the detection signal is a sensor installed at an entrance such as a front door.

[0030] If the detection signal processing unit 19b determines that the sensor that sent the detection signal is a sensor installed at an entrance or exit such as the front door, the detected intruder is likely to be a resident returning home or a legitimate office user, so it outputs a start signal for the entrance timer to the timer 12.

[0031] If the detection signal processing unit 19b determines that the sensor that transmitted the detection signal is not a sensor installed at an entrance such as the front door, the detection signal processing unit 19b performs the following process. If the current operation mode stored in the operation mode data 18c is the "security mode", the detection signal processing unit 19b passes an alarm transmission instruction to the alarm transmitting unit 19d. If the current operation mode stored in the operation mode data 18c is the "home mode", the detection signal processing unit 19b determines whether the sensor that transmitted the detection signal is a sensor to be monitored that is stored in the monitored sensor data 18b. If the detection signal processing unit 19b determines that the sensor is a sensor to be monitored, the detection signal processing unit 19b outputs a start signal for a delay timer to the timer 12.

[0032] When a detection signal is input from the sensor or when a release mode setting request or a security mode setting request is received from the authentication device 20, the detection signal processing unit 19b transmits a message output instruction corresponding to the current operation mode stored in the operation mode data 18c to the authentication device 20 via the transmission / reception unit 17. When the current operation mode stored in the operation mode data 18c is the "release mode", the detection signal processing unit 19b does not monitor intruders into the house to be monitored, and therefore ignores the detection signal related to intrusion even if it is received.

[0033] The operation mode control unit 19c is a processing unit that performs control related to the setting of the operation mode. When the operation mode control unit 19c receives a release mode setting request from the authentication device 20 via the transmission / reception unit 17, the operation mode control unit 19c performs the following process. If the current operation mode stored in the operation mode data 18c is the "security mode", the operation mode is set to the "release mode", and the "release mode" that is the set operation mode is stored in the operation mode data 18c of the storage unit 18 as a new operation mode. Then, a message output instruction including a message ID "MSG03" for notifying a resident who has returned home that the operation mode has been set to the "release mode" is transmitted to the authentication device 20 via the transmission / reception unit 17. Also, if the current operation mode stored in the operation mode data 18c is the "home mode", a message output instruction including a message ID "MSG05" for notifying a resident who has returned home that the operation mode is the "home mode" is transmitted to the authentication device 20 via the transmission / reception unit 17. When the current operation mode stored in the operation mode data 18c is the "release mode", the operation mode setting process is not performed, and a notification is given that the operation mode is already the release mode.

[0034] If the entrance timer or delay timer times out before the operation mode control unit 19c receives a release mode setting request from the authentication device 20 via the transceiver unit 17, the detection signal processing unit 19b passes an alarm transmission instruction to the alarm transmission unit 19d.

[0035] When the operation mode control unit 19c receives a security mode setting request from the authentication device 20 via the transmission / reception unit 17, it outputs a start signal for the exit timer to the timer 12. It also transmits a message output instruction including the message ID "MSG06" to the authentication device 20 via the transmission / reception unit 17, notifying that the operation mode is to be set to "security mode" to prompt the user to exit from the monitored area. Then, when the exit timer times out, it sets the operation mode to "security mode" and stores the set operation mode, "security mode", in the operation mode data 18c of the storage unit 18 as a new operation mode.

[0036] The alarm transmitting unit 19d is a processing unit that transmits an alarm When the alarm transmitting unit 19d receives an instruction to transmit an alarm from the detection signal processing unit 19b, the alarm transmitting unit 19d transmits an alarm to a monitoring center of a security company or the like.

[0037] Next, a description will be given of a specific example of data stored in the storage unit 18 of the control device 10 shown in Fig. 2. Fig. 3 is a diagram showing an example of the sensor data 18a, the monitored sensor data 18b, and the operation mode data 18c shown in Fig. 2.

[0038] The sensor data 18a shown in Fig. 3(a) stores a sensor ID given to each sensor, a type of event detected by the sensor, and an installation location of the sensor in association with each other. In the example shown in Fig. 3(a), a state in which the type is "intrusion" and the installation location is "entrance" is associated with the sensor ID "001", a state in which the type is "intrusion" and the installation location is "corridor" is associated with the sensor ID "002", a state in which the type is "intrusion" and the installation location is "window" is associated with the sensor ID "003", a state in which the type is "fire" and the installation location is "kitchen" is associated with the sensor ID "004", a state in which the type is "gas leak" and the installation location is "kitchen" is associated with the sensor ID "005", and a state in which the type is "emergency" and the installation location is "living room" is associated with the sensor ID "006".

[0039] The monitored sensor data 18b shown in Fig. 3(b) stores the sensor IDs of the sensors to be monitored when the at-home mode is set as the operation mode. The example shown in Fig. 3(b) shows a state in which the sensor IDs "001, 003" are stored as the monitored sensors. The operation mode data 18c shown in Fig. 3(c) stores the current operation mode. The example shown in Fig. 3(c) shows a state in which the "at-home mode" is stored as the operation mode.

[0040] <Configuration of authentication device 20> Next, the configuration of the authentication device 20 will be described. Fig. 4 is a functional block diagram showing the configuration of the authentication device 20 shown in Fig. 1. As shown in Fig. 4, the authentication device 20 has an input / output unit 21, a human detection unit 22, a reading unit 23, a transmission / reception unit 27, a storage unit 28, and a control unit 29. The authentication device 20 is installed near an entrance such as a front door inside a house.

[0041] The input / output unit 21 is an input / output device consisting of a touch panel display, buttons, a microphone, a speaker, etc., and displays various information output from the control unit 29 as characters, figures, etc., or outputs it as sound, etc., and outputs signals to the control unit 29 in response to operations by the operator, sound input, etc.

[0042] The human detection unit 22 is a sensor that detects the presence of a person, and outputs a detection signal to the control unit 29 when the human presence is detected near an entrance or exit such as the front door of a house, which is the detection area of ​​this sensor.

[0043] The reading unit 23 is an input / output device that transmits and receives signals to and from the mobile terminal 30. When an activation signal is input from the control unit 29, the reading unit 23 transmits an interrogation signal. Then, when a response signal is received from the mobile terminal 30, the reading unit 23 outputs the response signal to the control unit 29.

[0044] The transmitting / receiving unit 27 is an interface unit for transmitting and receiving signals to and from the control device 10. When a signal is input from the control unit 29, the transmitting / receiving unit 27 transmits the signal to the control device 10, and when a signal is received from the control device 10, the transmitting / receiving unit 27 outputs the received signal to the control unit 29.

[0045] The storage unit 28 is a storage device formed of a non-volatile memory or a hard disk device, and stores message data 28a and terminal data 28b. The message data 28a is data representing text data and voice data output from the input / output unit 21. The terminal data 28b is data representing terminal information of the mobile terminal 30 of a resident that has been registered in advance.

[0046] The control unit 29 is a control unit that performs overall control of the authentication device 20, and has a terminal registration unit 29a, a human detection processing unit 29b, a reading processing unit 29c, a terminal authentication unit 29d, a terminal information display unit 29e, a security operation reception unit 29f, and an alarm unit 29g. In practice, by loading these programs into a CPU and executing them, the terminal registration unit 29a, the human detection processing unit 29b, the reading processing unit 29c, the terminal authentication unit 29d, the terminal information display unit 29e, the security operation reception unit 29f, and the alarm unit 29g are caused to execute processes corresponding thereto.

[0047] The terminal registration unit 29a is a processing unit that manages the terminal data 28b. When terminal information related to the mobile terminal 30 is input from the input / output unit 21, the terminal registration unit 29a stores the input terminal information in the terminal data 28b. The terminal information related to the mobile terminal 30 includes a terminal ID, a display name, and authority to change the operation mode.

[0048] The human detection processing unit 29b is a processing unit that judges whether or not there is a person near the authentication device 20 based on the input of a detection signal from the human body detection unit 22. If the human detection processing unit 29b judges that a detection signal is input from the human detection unit 22, that is, that there is a person near the authentication device 20, it outputs an activation signal to the reading unit 23.

[0049] The reading processing unit 29c is a processing unit that identifies the terminal ID from the response signal of the portable terminal 30 received by the reading unit 23. When the reading processing unit 29c receives a response signal from the portable terminal 30 via the reading unit 23, it identifies the terminal ID of the portable terminal 30 from the response signal and passes it to the terminal authentication unit 29d and the terminal information display unit 29e.

[0050] If the reading processing unit 29c does not receive a response signal from the mobile terminal 30 within a predetermined time after the human detection processing unit 29b outputs an activation signal to the reading unit 23, the reading processing unit 29c passes the message ID "MSG02" to the notification unit 29g.

[0051] The terminal authentication unit 29d is a processing unit that authenticates that the terminal ID of the portable terminal 30 received from the reading processing unit 29c has the authority to change the operation mode. The terminal authentication unit 29d determines whether the received terminal ID is a terminal ID of the portable terminal 30 that has been registered in advance, using the terminal ID received from the reading processing unit 29c and the terminal data 28b stored in the storage unit 28. If it is determined that the received terminal ID is a terminal ID that has been registered in advance, the terminal authentication unit 29d authenticates that this terminal ID has the authority to change the operation mode.

[0052] If the terminal ID determined to be pre-registered has authority to change the operation mode, the terminal authentication unit 29d transmits a release mode setting request including this terminal ID to the control device 10 via the transmission / reception unit 27. Thereafter, when the terminal authentication unit 29d receives a notification from the control device 10 via the transmission / reception unit 27 that the operation mode is already the release mode, it passes a security operation reception instruction to the security operation reception unit 29f and passes the terminal ID to the terminal information display unit 29e.

[0053] If the terminal ID determined to be pre-registered does not have the authority to change the operation mode or is not registered in the terminal data 28b, the terminal authentication unit 29d passes the message ID "MSG02" to the notification unit 29g.

[0054] The terminal information display unit 29e is a processing unit that displays terminal information of the mobile terminal 30. When the terminal information display unit 29e receives a terminal ID from the terminal authentication unit 29d, the terminal information display unit 29e extracts terminal information related to the terminal ID from the terminal data 28b and outputs the extracted terminal information to the input / output unit 21.

[0055] If the terminal ID of the mobile terminal 30 received from the reading processing unit 29c is a terminal ID that has been registered in advance but does not have the authority to change the operation mode, the terminal authentication unit 29d may not pass the security operation reception instruction to the security operation reception unit 29f, but may pass the terminal ID to the terminal information display unit 29e. In this case, when the human body detection unit 22 detects the presence of a person near an entrance such as a front door, the terminal information of the mobile terminal 30 that received the response signal is displayed by the reading unit 23, but a security setting screen for receiving security operations, which will be described later, is not displayed. This makes it possible to notify the resident near the entrance of the possession of the mobile terminal 30.

[0056] The security operation receiving unit 29f is a processing unit that receives an operation for setting the operation mode to the security mode (hereinafter referred to as a "security operation"). When the security operation receiving unit 29f receives a security operation reception instruction from the terminal authentication unit 29d, it outputs a security setting screen to the input / output unit 21. Then, the input / output unit 21 determines whether or not the security operation has been received.

[0057] When the security operation receiving section 29f receives a security operation at the input / output section 21, it outputs a security mode setting request to the transmitting / receiving section 27 and transmits it to the control device 10 via the transmitting / receiving section 27.

[0058] The notification unit 29g is a processing unit that outputs a message by characters or voice. When the notification unit 29g receives a message ID from the reading processing unit 29c or the terminal authentication unit 29d, the notification unit 29g extracts text data and voice data corresponding to the message ID from the message data 28a and outputs the extracted text data and voice data to the input / output unit 21.

[0059] When the notification unit 29g receives a message output instruction from the control device 10 via the transmission / reception unit 27, it extracts the text data and audio data corresponding to the message ID from the message data 28a based on the message ID included in the received message output instruction, and outputs each of them to the input / output unit 21.

[0060] Next, a specific example of data stored in the storage unit 28 of the authentication device 20 shown in Fig. 4 will be described. Fig. 5 is a diagram showing an example of the message data 28a and the terminal data 28b shown in Fig. 4.

[0061] Message data 28a shown in Figure 5 (a) associates a state in which the text is "Security is in effect. Please deactivate security" and the audio is "MSG01.mp3" with message ID "MSG01", a state in which the text is "Authentication failed" and the audio is "MSG02.mp3" with message ID "MSG02", and a state in which the text is "Security has been deactivated" and the audio is "MSG03.mp3" with message ID "MSG03".

[0062] In addition, message data 28a associates a state in which the text is "Home security guard in progress. Please end security guard duties" and the audio is "MSG04.mp3" with message ID "MSG04", a state in which the text is "Home security guard duties will continue" and the audio is "MSG05.mp3" with message ID "MSG05", and a state in which the text is "Security guard duties will begin" and the audio is "MSG06.mp3" with message ID "MSG06".

[0063] The terminal data 28b shown in Figure 5 (b) associates the display name "Dad's smartphone" and a state in which the authority is "Yes" with the terminal ID "QWERT", the display name "Mom's smartphone" and a state in which the authority is "Yes" with the terminal ID "ASDFG", the display name "Work smartphone" and a state in which the authority is "No" with the terminal ID "ZXCVB", and the display name "Monitoring tag" and a state in which the authority is "No" with the terminal ID "POIUY".

[0064] <Example of display on authentication device 20> Next, an example of the display in the authentication device 20 will be described. FIG. 6 is a diagram showing an example of the display in the authentication device 20. When the authentication device 20 detects a registered mobile terminal 30, it displays the display name of the detected mobile terminal 30. At this time, the display arrangement and the character size are changed according to the number of detected mobile terminals 30. In addition, if the detected mobile terminals 30 include a mobile terminal 30 registered as having the authority to change the operation mode, a security button for accepting a security operation, which is an operation for setting the operation mode to a security mode, is displayed. Note that if a mobile terminal 30 registered as having the authority to change the operation mode is not included, unnecessary information can be omitted by not displaying the security button.

[0065] As shown in Fig. 6(a), when only one mobile terminal 30 is detected, the display size is set to "large". Specifically, "Mobile terminal detected" and "Dad's smartphone" are displayed, with the former and latter displayed in "large" font size. The mobile terminal 30 with the display name "Dad's smartphone" is registered as having the authority to change the operation mode, so the security button is displayed.

[0066] As shown in Fig. 6(b), when three mobile terminals 30 are detected, the display size is set to "large". Specifically, "Mobile terminal detected" and "Dad's smartphone, Mom's smartphone, Work smartphone" are displayed, with the former and latter displayed in "large" font size. Then, for each of the mobile terminals 30 with the display name "Dad's smartphone" and "Mom's smartphone", both are registered as having the authority to change the operation mode, so a security button is displayed.

[0067] As shown in Fig. 6(c), when four mobile terminals 30 are detected, the display size of the characters is divided and displayed. Specifically, "Mobile terminal detected" is displayed in "large" character size, and "Dad's smartphone, Mom's smartphone, Work smartphone, Monitoring tag" are displayed in "small" character size and in two columns. Then, for each of the mobile terminals 30 with the display name "Dad's smartphone" and "Mom's smartphone", the security button is displayed because both are registered as having the authority to change the operation mode.

[0068] 6(d) shows an example in which two mobile terminals 30 are detected and the display names of the mobile terminals 30 are "Work Smartphone, Monitoring Tag". For each of the mobile terminals 30 with the display names "Work Smartphone" and "Monitoring Tag", the security button is not displayed because neither of them is registered as having the authority to change the operation mode.

[0069] In this embodiment, an example will be described in which the name of the owner is displayed as the display name, but this is not limited to this, and as long as the user can recognize which mobile device he or she is referring to, the display name may be the mobile device's telephone number, a figure, a symbol, color coding, etc.

[0070] In addition, in this embodiment, a person is authenticated using the terminal ID of the mobile terminal 30, but this is not limited to this, and a person may be authenticated using biometric information (face, iris, voice, etc.) acquired by a camera or microphone.

[0071] <Processing procedure during security mode> Next, the processing procedure in the security mode will be described with reference to the flowchart of FIG 7.

[0072] 7, when a sensor installed at an entrance or window such as the front door detects the opening or closing of a door or window, or when an intrusion detection sensor installed in a hallway or the like detects a person, the sensor that detected the detection transmits a detection signal to the control device 10. The control unit 19 of the control device 10 waits for a detection signal from the sensor (step S101; No), and upon receiving a detection signal (step S101; Yes), determines that there is a possibility of an intruder, and uses this detection signal and the sensor data 18a stored in the memory unit 18 to determine whether or not the sensor that transmitted the detection signal is a sensor installed at an entrance or exit such as the front door (step S102).

[0073] If the sensor that sent the detection signal was a sensor installed at an entrance such as the front door (step S102; Yes), the detected person may be a resident returning home or a legitimate office user, so the control unit 19 of the control device 10 outputs a start signal to the timer 12 to start the entrance timer that suspends the transmission of an alarm (step S103). Then, to inform the detected person that the current operation mode of the security system is "security mode", a message output instruction including the message ID "MSG01" is sent to the authentication device 20 via the transmission / reception unit 17 (step S104).

[0074] When the control unit 29 of the authentication device 20 receives a message output instruction from the control device 10 via the transmitting / receiving unit 27, it judges whether or not a detection signal has been input from the human detection unit 22, that is, whether or not a person is near the authentication device 20 (step S105). When it is judged that a detection signal has been input from the human detection unit 22, that is, that a person is near the authentication device 20 (step S105; Yes), it outputs an activation signal to the reading unit 23.

[0075] The reader 23 to which the activation signal has been input transmits an interrogation signal. Then, when a response signal is received from the mobile terminal 30, the reader 23 outputs the response signal to the controller 29. When the controller 29 receives the response signal, the controller 29 identifies the terminal ID of the mobile terminal 30 from the response signal, and uses the terminal ID and the terminal data 28b stored in the memory 28 to authenticate that the identified terminal ID has the authority to change the operation mode (step S107).

[0076] At this time, the control unit 29 of the authentication device 20 measures the distance and direction to the mobile terminal 30 based on the radio wave strength of the response signal, etc., to identify the position of the mobile terminal 30, and if the mobile terminal 30 is not in a predetermined area (for example, within a predetermined distance in front of the authentication device 20, or within a predetermined distance inside the entrance from the door, etc.), the control unit 29 may not identify the terminal ID of the mobile terminal 30, or may not allow the operation mode change process to be performed even if the terminal ID of the mobile terminal 30 has the authority to change the operation mode, that is, may not perform authentication. This makes it possible to prevent unintended authentication process from being performed when the person carrying the mobile terminal 30 is near the outside of the door.

[0077] In step S107, if the identified terminal ID has the authority to change the operating mode and authentication is performed (step S107; Yes), a release mode setting request including this terminal ID is transmitted to the control device 10 via the transceiver 27 (step S109).

[0078] When the control unit 19 of the control device 10 receives a request to set the release mode from the authentication device 20 via the transmission / reception unit 17 (step S110; Yes), it sets the operation mode to the "release mode" (step S111) and stores the set operation mode, that is, the "release mode", as a new operation mode in the operation mode data 18c of the memory unit 18.

[0079] The control unit 19 of the control device 10 transmits a message output instruction including the message ID "MSG03" to the authentication device 20 via the transmission / reception unit 17 to notify that the operation mode has been switched to the "release mode" (step S112).

[0080] When the control unit 29 of the authentication device 20 receives a message output instruction from the control device 10 via the transmission / reception unit 27, it extracts text data and voice data corresponding to the message ID "MSG03" from the message data 28a stored in the storage unit 28 based on the message ID "MSG03" included in the message output instruction, and outputs the data to the input / output unit 21. The input / output unit 21 outputs text and voice to notify that the operation mode has been switched to the "release mode" based on the text data and voice data from the control unit 29 (step S113), and ends the process. This allows the resident who has returned home to know that the security of the security system has been released.

[0081] In addition, if the control unit 29 of the authentication device 20 determines in step S105 that no detection signal has been input from the human detection unit 22, i.e., that there is no person near the authentication device 20 (step S105; No), it extracts from the memory unit 28 the text data and audio data corresponding to the message ID "MSG01" included in the message output instruction received from the control device 10, and outputs a message in text or audio form to notify the person detected by the input / output unit 21 that the current operating mode is "security mode" (step S106), and returns to step S105.

[0082] Furthermore, if the control unit 29 of the authentication device 20 determines in step S107 that the terminal ID does not have the authority to change the operating mode or if it cannot receive a response signal from a mobile terminal 30 that has the authority to change the operating mode (step S107; No), it extracts the text data and voice data corresponding to the message ID "MSG02" from the memory unit 28, outputs a message in text or voice notifying the input / output unit 21 that authentication is not possible (step S108), and returns to step S105.

[0083] Furthermore, in step S110, if the control unit 19 of the control device 10 has not received a release mode setting request from the authentication device 20 via the transmitting / receiving unit 17 (step S110; No), it judges whether the entrance timer has timed out, that is, whether a predetermined time has elapsed since the sensor installed at the entrance / exit detected a person (step S114). If the entrance timer has not timed out (step S114; No), the process returns to step S110. If the entrance timer has timed out (step S114; Yes), it judges that the person detected by the sensor is an unauthorized intruder, transmits an alarm to a security company's monitoring center or the like (step S115), and ends the process.

[0084] Furthermore, if the sensor that transmitted the detection signal in step S102 is not a sensor installed at an entrance such as the front door (step S102; No), the control unit 19 of the control device 10 determines that the sensor has detected an unauthorized intruder, transmits an alarm to a security company's monitoring center or the like (step S115), and terminates the process.

[0085] <Processing procedure in home mode> Next, the processing procedure in the at-home mode will be described with reference to the flowchart of FIG 8.

[0086] As shown in FIG. 8, the control unit 19 of the control device 10 waits for a detection signal from a sensor (step S201; No). When the control unit 19 receives a detection signal (step S201; Yes), it determines that there is a possibility of an intruder, and uses the detection signal and the sensor data 18a stored in the memory unit 18 to determine whether the sensor that sent the detection signal is a sensor installed at an entrance or exit such as the front door (step S202).

[0087] If the sensor that sent the detection signal was a sensor installed at an entrance such as the front door (step S202; Yes), the detected intruder may be a resident who has returned home or a legitimate user of the office, so the control unit 19 of the control device 10 outputs a start signal to the timer 12 to start the entrance timer that suspends the transmission of an alarm (step S203). Then, to notify the detected person that the current operation mode of the security system is "home mode", a message output instruction including the message ID "MSG04" is sent to the authentication device 20 via the transmission / reception unit 17 (step S205).

[0088] When the control unit 29 of the authentication device 20 receives the message output instruction from the control device 10 via the transmitting / receiving unit 27, it judges whether or not a detection signal is input from the human detection unit 22 (step S206). When it judges that a detection signal is input from the human detection unit 22 (step S206; Yes), it outputs an activation signal to the reading unit 23.

[0089] The reader 23 to which the activation signal has been input transmits an interrogation signal. Then, when a response signal is received from the mobile terminal 30, the reader 23 outputs the response signal to the controller 29. When the controller 29 receives the response signal, the controller 29 identifies the terminal ID of the mobile terminal 30 from the response signal, and uses the terminal ID and the terminal data 28b stored in the memory 28 to authenticate that the identified terminal ID has the authority to change the operation mode (step S208).

[0090] If the authenticated terminal ID has the authority to change the operation mode (step S208; Yes), a release mode setting request including this terminal ID is transmitted to the control device 10 via the transmission / reception unit 27 (step S210).

[0091] When the control unit 19 of the control device 10 receives a release mode setting request from the authentication device 20 via the transmission / reception unit 17 (step S211; Yes), it transmits a message output instruction including the message ID "MSG05" to the authentication device 20 via the transmission / reception unit 17 to notify that the current operating mode is the home mode and that the home mode will be continued (step S212).

[0092] When the control unit 29 of the authentication device 20 receives a message output instruction from the control device 10 via the transmission / reception unit 27, it extracts text data and voice data corresponding to the message ID "MSG05" from the message data 28a stored in the storage unit 28 based on the message ID "MSG05" included in the message output instruction, and outputs the data to the input / output unit 21. The input / output unit 21 outputs text and voice to notify that the current operation mode is "home mode" based on the text data and voice data from the control unit 29 (step S213), and ends the process. This allows a resident or the like who has returned home to recognize that the monitored subject is in home mode.

[0093] In addition, if the control unit 29 of the authentication device 20 does not receive a detection signal from the human detection unit 22 in step S206 (step S206; No), it extracts from the memory unit 28 the text data and voice data corresponding to the message ID "MSG04" included in the message output instruction received from the control device 10, notifies the person detected by the input / output unit 21 that the current operation mode is "home mode", and outputs a message in text and voice prompting the user to switch the operation mode to "cancellation mode" (step S207), and returns to step S206.

[0094] Furthermore, if the control unit 29 of the authentication device 20 determines in step S208 that the terminal ID does not have the authority to change the operating mode or if it cannot receive a response signal from a mobile terminal 30 that has the authority to change the operating mode (step S208; No), it extracts the text data and voice data corresponding to the message ID "MSG02" from the memory unit 28, and outputs a message in text or voice notifying the input / output unit 21 that authentication is not possible (step S209), and returns to step S206.

[0095] Furthermore, if the control unit 19 of the control device 10 detects in step S202 that the sensor that transmitted the detection signal was not a sensor installed at an entrance such as the front door (step S202; No), there is a possibility that the signal was a false alarm, such as when a legitimate resident or office user opened a window for ventilation, and so the control unit 19 outputs a start signal to the timer to start a delay timer that suspends the transmission of the alarm (step S204), and proceeds to step S205.

[0096] Furthermore, if the control unit 19 of the control device 10 has not received a release mode setting request from the authentication device 20 via the transceiver unit 17 in step S211 (step S211; No), it determines whether the entrance timer or delay timer has timed out, i.e., whether a predetermined time has elapsed since receiving a detection signal from a sensor installed at the entrance / exit or a sensor set as a monitored object (step S214).

[0097] If the entrance timer or the delay timer has not timed out (step S214; No), the process returns to step S211. If the entrance timer or the delay timer has timed out (step S214; Yes), the sensor determines that it has detected an unauthorized intruder, transmits an alarm to a security company's monitoring center or the like (step S215), and ends the process.

[0098] <Processing procedure in release mode> Next, the processing procedure in the security mode will be described with reference to the flowchart of FIG 9, which shows the processing procedure in the release mode.

[0099] When the control unit 19 of the control device 10 receives a detection signal from a sensor via the transmission / reception unit 17 during the release mode, if the type of event detected by the sensor that sent the received detection signal is a "fire," "gas leak," "emergency call," etc., it will send an alarm or report it to a security company, police, fire department, etc., but if it is an "intrusion," it will ignore it and will not send an alarm, etc.

[0100] 9, when a resident or the like comes to an entrance such as the front door to go out and enters the detection area of ​​the human detection unit 22 of the authentication device 20, a detection signal is output from the human detection unit 22 to the control unit 29. When the control unit 29 of the authentication device 20 receives the detection signal from the human detection unit 22 (step S301; Yes), it outputs an activation signal to the reading unit 23. When the activation signal from the control unit 29 of the authentication device 20 is input, the reading unit 23 transmits a question signal, and when a response signal is received from the mobile terminal 30, it outputs the response signal to the control unit 29.

[0101] When the control unit 29 of the authentication device 20 receives a response signal from the mobile terminal 30 via the reading unit 23, it identifies the terminal ID of the mobile terminal 30 from the response signal, and uses this terminal ID and the terminal data 28b stored in the memory unit 28 to determine whether the detected terminal ID is a terminal that has been registered in advance (step S302).

[0102] If the detected terminal ID is a terminal that has been registered in advance (step S302; Yes), the display name of this terminal is read from the terminal data 28b, the read display name is output to the input / output unit 21, and the detected terminal is output by characters, voice, or the like (step S303). This allows a person who is about to go out to recognize that he or she is not carrying a mobile terminal 30 such as a smartphone.

[0103] Furthermore, the control unit 29 of the authentication device 20 uses the identified terminal ID and the terminal data 28b stored in the storage unit 28 to authenticate that this terminal ID has the authority to change the operation mode (step S304). If this terminal ID has the authority to change the operation mode (step S304; Yes), a security button is displayed to accept a security operation, which is an operation to set the operation mode to the security mode. Thereafter, the control unit 29 determines whether or not a security operation to operate the security button has been accepted in the input / output unit 21 (step S305).

[0104] If the input / output unit 21 accepts a security operation (step S305; Yes), a security mode setting request including the identified terminal ID is output to the transceiver unit 27 and transmitted to the control device 10 via the transceiver unit 27 (step S307).

[0105] In step S302, if the identified terminal ID is a terminal that has been registered in advance, the control unit 29 of the authentication device 20 notifies the name of the detected terminal in step S303. However, instead of notifying at this timing, it may be configured to determine in step S304 that the identified terminal ID has the authority to change the operation mode, transmit a release mode setting request via the transmission / reception unit 27, and then notify the detected terminal when a notification is received from the control unit 19 of the control device 10 that the current operation mode is already the release mode (operation switching process has failed). In this way, since the display is performed only when the operation mode is the release mode, unnecessary notifications are not made during security mode or at-home mode, and a person who should have the mobile terminal 30 with the authority to set the operation mode can check whether or not the mobile terminal 30 is in his / her possession by checking the notification content when leaving the house.

[0106] When the control unit 19 of the control device 10 receives a security mode setting request from the authentication device 20 via the transceiver unit 17 (step S308; Yes), it outputs a start signal to the timer and starts an exit timer that measures the time during which no alarm is sent based on a detection signal from a sensor installed at a position through which a resident or other person (hereinafter referred to as an "exiting person") who is about to go out exits through an entrance such as the front door (step S309).

[0107] The control unit 19 of the control device 10 transmits a message output instruction including the message ID "MSG06" to the authentication device 20 via the transmission / reception unit 17 to prompt the exiting person to exit from the monitoring target (step S310).

[0108] When the control unit 29 of the authentication device 20 receives a message output instruction from the control device 10 via the transmission / reception unit 27, it extracts text data and voice data corresponding to the message ID "MSG06" from the message data 28a stored in the storage unit 28 based on the message ID "MSG06" included in the message output instruction, and outputs the data to the input / output unit 21. Based on the text data and voice data from the control unit 29, the input / output unit 21 outputs a message in text or voice urging the user to leave the monitored area because the mode will soon be switched to security mode (step S313). This allows a resident or the like who is about to go out to recognize that the process of switching to security mode has been performed correctly.

[0109] When the exit timer expires (step S311; Yes), the control unit 19 of the control device 10 sets the operation mode to "security mode" (step S312), outputs the set operation mode, "security mode," to the memory unit 18 as the new operation mode, stores it in the operation mode data 18c, and terminates the process.

[0110] In addition, the control unit 29 of the authentication device 20 returns to step S301 if no detection signal is input from the human detection unit 22 in step S301 (step S301; No), if no terminal ID is detected in step S302 or the detected terminal ID is not a pre-registered terminal ID (step S302; No), or if the terminal ID does not have the authority to change the operating mode in step S304 (step S304; No).

[0111] Furthermore, if the control unit 29 of the authentication device 20 does not accept any operation on the display input unit 21 at step S305 (step S305; No), it outputs an unlock mode setting request including the identified terminal ID to the transceiver unit 27 and transmits it to the control device 10 via the transceiver unit 27 (step S306).

[0112] When the control unit 19 of the control device 10 receives the release mode setting request from the authentication device 20 via the transmission / reception unit 17 (step S308; No), it checks the operation mode of the operation mode data 18c stored in the storage unit 18. At this time, since the operation mode is already the "release mode", it does not perform the operation mode switching process and ends the process as it is.

[0113] Furthermore, in step S311, if the exit timer has not timed out (step S311; No), the control unit 19 of the control device 10 waits until the exit timer times out.

[0114] In addition, the control device 10 stores the sensors to be monitored during the at-home mode in the monitored sensor data 18b of the storage unit 18 in advance, and when a resident or the like performs a setting operation to the "at-home mode" via the input unit 11, the control device 10 sets the operation mode to the "at-home mode" with the sensors stored in the monitored sensor data 18b as the monitored objects, and stores the set operation mode, "at-home mode", in the operation mode data 18c of the storage unit 28 as a new operation mode. At this time, the resident or the like may specify the sensor to be monitored via the input unit 11. In this case, the control unit 19 of the control device 10 stores the operation mode as the "at-home mode" and stores the sensor specified via the input unit 11 as the sensor to be monitored. Here, an example in which the "at-home mode" is set by operating the input unit 11 provided in the control device 10 has been described, but the present invention is not limited to this, and the setting operation may be performed via an operating device provided separately from the control device 10 or a mobile terminal 30 such as a smartphone. In this case, the control device 10 does not need to be provided with the input unit 11.

[0115] As described above, the security system is configured to authenticate pre-registered mobile terminals and then reset or continue the operation mode depending on the setting status of the operation mode, so that operation modes including home mode can be efficiently set and released.

[0116] Note that the configurations illustrated in the above embodiments are merely functional schematics and do not necessarily have to be physically configured as illustrated. In other words, the form of distribution and integration of each device is not limited to that illustrated, and all or part of the devices can be functionally or physically distributed and integrated in any unit according to various loads, usage conditions, etc. [Industrial Applicability]
