Description

Technical Field

[0001] The present invention relates to a security device that detects the occurrence of abnormal events such as the intrusion of a suspicious person and notifies thereof.

Background Art

[0002] In many cases, so-called security devices are provided in offices, schools, commercial facilities, etc. where there are no users at night or on holidays. In addition, security devices are also being used in ordinary houses in order to ensure safety at night when residents are often absent due to going out or when they cannot see due to going to bed. For example, as shown in FIG. 14, a security device 10 disposed in various security target facilities 1 is connected to various abnormality detection sensors such as a fire sensor SX1 and an intrusion sensor SX2.

[0003] The fire sensor SX1 includes a smoke sensor that detects smoke, a heat sensor that detects heat, and the like. The intrusion sensor SX2 includes a human presence sensor that uses infrared rays, ultrasonic waves, visible light, etc. to sense the presence of a person, an opening / closing sensor that uses magnetism or acceleration to detect the opening and closing of doors and windows, an impact sensor that detects an impact when windows, doors, etc. are damaged, and the like. These various abnormality detection sensors are connected to the sensor input circuit unit 11 of the security device 10. When the sensor input circuit unit 11 of the security device 10 monitors the output signals from each abnormality detection sensor SX1, SX2,... and detects the occurrence of an abnormality, it makes a notification to, for example, the security company 3's security target accommodation device 30, which is a predetermined notification destination, through the wide area network 2.

[0004] The wide area network 2 is a communication network such as a general public telephone network, a mobile phone network, or the Internet. In the security company 3, when the security target accommodation device 30 receives a notification from the security device 10 of the security target facility 1, it notifies the monitor 40 by, for example, sounding the received message. The monitor 40 operates the security target accommodation device 30 to identify the notification source and instructs the security guard 50 to dispatch to the notification source. As a result, it becomes possible for the security guard to quickly dispatch to the security target facility 1 where an abnormality has occurred and take appropriate measures.

[0005] It is necessary to perform a state switching operation to switch the security device between the security state (monitoring state) and the non-security state (non-monitoring state). In the security state, the output signal from the abnormality detection sensor is monitored, and a notification is made when an abnormality is detected. In the non-security state, the output signal from the abnormality detection sensor is not monitored, and no notification is made. Therefore, through the operation panel connected to the security device, switch from the non-security state to the security state when leaving work or going out, and switch from the security state to the non-security state when going to work or returning home.

[0006] Patent Document 1 described later discloses an invention in which a call is made from a mobile phone terminal to a management center device, and the start / end of the mechanical security of a predetermined security device (security state / non-security state of the security device) is switched according to the sub-address number of the called party of the management center device. In the case of the invention disclosed in Patent Document 1, it is not necessary to provide an operation panel on the security device, and the security state / non-security state of the security device can be switched from an appropriate position. Thereby, it is expected to simplify the configuration of the security device and improve the convenience for the users of the security device.

Summary of the Invention

Problems to be Solved by the Invention

[0008] While the invention disclosed in Patent Document 1 has advantages, it also has the disadvantage that if a failure occurs in the network connecting the management center device and the mobile phone terminal, it is not possible to switch the security device between security and non-security states. Also, if the mobile phone terminal is forgotten or dropped and is no longer available, it is not possible to switch the security device between security and non-security states. For this reason, it is necessary to provide the security device with an operation terminal (operation panel) that enables switching between security and non-security states.

[0009] However, when switching between the security state and non-security state of a security device through an operation terminal, the user must enter the facility to be secured and operate the operation terminal. As a result, the user is detected as an intruder, an alarm buzzer sounds, and the user becomes the subject of a report (alert) to a designated reporting destination such as a security company. In order to prevent unnecessary reports (alerts) from being made in such cases, security start guard sensor functions and security release guard sensor functions have been provided as functions of security devices that switch between the security state and non-security state through an operation terminal.

[0010] The security start guard sensor function prevents an alarm from being issued when the intrusion sensor detects a user (facility personnel) as an intruder as soon as the security start operation on the operating terminal switches to security mode. Specifically, this function prevents an alarm from being issued if the intrusion sensor stops responding between the security start operation and the elapse of a predetermined alarm grace period. If the intrusion sensor responds after the alarm grace period has elapsed, an alarm is issued because there is a high possibility that this is an abnormal intrusion (an intrusion by someone other than a legitimate user). When the security start operation is performed, a response is taken through the operating terminal on which the operation was performed to encourage the user to leave the room (leave), using sounds such as a buzzer or a display. This response ends after the alarm grace period has elapsed.

[0011] The guard release sensor function avoids an alarm being triggered when a user (facility staff) is detected as an intruder by the intrusion sensor before a guard release operation is performed to switch to a non-guarded state. Specifically, if a guard release operation is performed on the operation terminal within a predetermined alarm delay time after the intrusion sensor detects the occurrence of an intrusion, the function will not trigger an alarm. If the guard release operation is not performed before the alarm delay time elapses, an alarm will be triggered because there is a high possibility of an abnormal intrusion. When the intrusion sensor detects the occurrence of an intrusion, for example, through the operation terminal where the operation is performed, measures are taken to prompt the user to perform a guard release operation, such as making a sound like a buzzer or displaying a message. This measure will end if a guard release operation is performed within the alarm delay time.

[0012] However, the buzzer or the like that sounds during the guard release sensor function has a larger volume because, unlike the buzzer or the like during the guard start sensor function, it also serves as a threatening sound to intruders. Therefore, for legitimate users (facility staff), during the guard release operation, a loud threatening sound is always emitted, which may cause surprise even if they are aware, or make them anxious about the guard release operation, resulting in annoyance.

[0013] In view of the above, the object of this invention is to eliminate the annoyance caused by the emission of an alarm sound (threatening sound) that notifies the occurrence of an intruder during the guard release operation in a guard device that performs a guard release operation through an operation terminal to transition to a non-guarded state.

Means for Solving the Problem

[0014] To solve the above problem, the guard device of the invention described in claim 1 sensor detection means for detecting the occurrence of an intrusion based on an output signal from an intrusion sensor that detects the occurrence of an intrusion by a person or the like, notification control means for controlling to notify the occurrence of an intrusion when the sensor detection means detects the occurrence of an intrusion, An operation state switching means for switching between a security state in which notification is made when an intrusion occurs and a non-security state in which no notification is made, in response to an instruction input from a user, Instruction input receiving means for receiving the instruction input including authentication information indicating that the user is a legitimate user; Base station communication means for enabling communication with the wireless communication terminal through a base station that enables connection of a wireless communication terminal that has been authenticated by performing wireless communication, comprising The notification control means is in the security state when the own device and when the occurrence of intrusion is detected by the sensor detection means, when there is no wireless communication terminal that can communicate through the base station communication means, immediately start notifying the occurrence of intrusion by a warning sound that is not a loud sound, and if the instruction input for switching to the non-alarm state is not received through the instruction input receiving means within a predetermined time, start emitting a threatening sound at a high volume; When the base station has authenticated and there is a wireless communication terminal that can communicate through the base station communication means, a notification of the occurrence of an intrusion is deter, and if the instruction input for switching to the non-alarm state is not received through the instruction input receiving means within a predetermined time, start emitting a threatening sound at a high volume characterized in that

[0015] According to the security device of the invention described in claim 1, the operation state switching means enables switching between the security state and the non-security state. Also, the base station communication means enables communication with the authenticated wireless communication terminal through a base station that enables connection of a wireless communication terminal that has been authenticated by performing wireless communication. When switched to the security state, when there is a wireless communication terminal that has been authenticated by the base station and can communicate through the base station communication means, the notification control means controls not to notify of the occurrence of an intrusion.

[0016] Thereby, when switching from the security state to the non-security state, if the wireless communication terminal possessed by a legitimate user becomes communicable with the security device, the notification process when an intruder is detected is suppressed. Therefore, a legitimate user can be made to be able to perform an operation of instructing to switch the security device from the security state to the non-security state with confidence.

Effect of the Invention

[0017] According to the present invention, in a security device that performs a security release operation through an operation terminal to transition to a non-security state, it is possible to suppress the emission of a threatening sound that notifies the occurrence of an intruder during the security release operation, and eliminate the annoyance of the user when switching to the non-security state.

[0019] Hereinafter, embodiments of the security device according to the present invention will be described with reference to the drawings. The security device described below is provided in various security target facilities such as offices, schools, commercial facilities, and ordinary houses. The security device detects the occurrence of an intrusion by a suspicious person or the like, emits a warning sound (threatening sound), and automatically reports to a predetermined reporting destination such as a security company. The security device described below can notify the surroundings or report to a predetermined reporting destination when it detects the occurrence of a fire, the occurrence of an intrusion by a person or the like, or a state where a door or window is broken and a person or the like can intrude.

[0020] However, what becomes a problem in the security device of the embodiment described below is the emission of a warning sound when a legitimate user releases the security state. Therefore, in the security device of the embodiment described below, when switching from the security state to the non-security state, the case where human intrusion is detected by a so-called human sensor or a door or window opening / closing sensor and notification to the surroundings is made will be described as an example.

[0021] [Configuration Example of Security System] FIG. 1 is a diagram for explaining a configuration example of a security system configured by using the security device 100 of this embodiment. As shown in FIG. 1, the security device 100 is connected to a security destination accommodation device 30 of a predetermined security company via a wide area network 2. The wide area network 2 is a communication network such as a public telephone network, a mobile phone network, or the Internet. When the security destination accommodation device 30 receives a notification from the security device 100, it identifies the notification source, emits a notification message, displays a map on the display screen, and indicates the location of the notification source, so that a supervisor can instruct a security guard to go out.

[0022] The security device 100 is an application of the embodiment of the security device according to the present invention and is installed in a safe place indoors of the security target facility. An operation terminal 200 and a plurality of intrusion sensors SS1, SS2,... are connected to the security device 100. The operation terminal 200 is indoors of the security target facility, but is installed in an appropriate place such as near an entrance / exit, and has functions such as receiving an operation input for switching between a security state and a non-security state, and emitting a notification sound. The notification sound includes a buzzer sound used as a threatening sound.

[0023] The intrusion sensors SS1, SS2,... detect the occurrence of an intrusion by a person or the like and supply an output signal to the security device. The intrusion sensors SS1, SS2,... use infrared rays, ultrasonic waves, visible light, etc., and are human sensors that sense the presence of a human, or opening / closing sensors that use magnetism or acceleration to detect the opening and closing of doors and windows. The intrusion sensors SS1, SS2,... are installed at places where a person or the like can intrude, such as entrances, exits, and windows. The reason for including a person or the like is that if an animal other than a person intrudes, it can be detected as an abnormality.

[0024] In this embodiment, the "security state" means a state in which the output signals from the intrusion sensors SS1, SS2, ... are monitored, and a notification can be made when an intrusion is detected. The "non-security state" means a state in which the output signals from the intrusion detection sensors are not monitored and no notification is made. Therefore, when the user of the security device 100 leaves work or goes out, the user can switch the security device 100 from the non-security state to the security state through the operation terminal 200 so that a notification can be automatically made when an intrusion is detected. Also, when the user of the security device 100 arrives at work or returns home (when returning from going out), the user can switch the security device 100 from the security state to the non-security state through the operation terminal 200 so that no notification is automatically made.

[0025] In addition, an access point (denoted as AP in the figure and abbreviated as AP hereinafter) 300 that functions as a so-called base station is connected to the security device 100 through a LAN (Local Area Network). In this embodiment, AP 300 complies with the Wi-Fi (registered trademark) standard. AP 300 performs wireless communication with wireless communication terminals existing in the vicinity and performs authentication processing using the ESSID (Extended Service Set Identifier) and password assigned to itself. Through the authentication processing, AP 300 enables connection to the security device 100 via itself for wireless communication terminals that have passed the authentication.

[0026] The wireless communication terminal 400 is a general-purpose terminal such as a smartphone or tablet PC (Personal Computer), has a wireless LAN interface conforming to the Wi-Fi (registered trademark) standard, and can connect to a LAN via a nearby AP (Access Point). In this embodiment, the wireless communication terminal 400 is possessed by a legitimate user of the security device 100, and is preset with an ESSID and a password assigned to the AP300 connected to the security device 100. Therefore, the wireless communication terminal 400 can be connected to the security device 100 via a LAN by wirelessly communicating with the AP300 and obtaining authentication.

[0027] The security device 100 also has a security start guard sensor function and a security release guard sensor function. That is, immediately after switching from the non-security state to the security state, the security start guard sensor function works. In this case, an alarm sound is emitted to encourage people to leave, and even if an intrusion is detected through the intrusion sensors SS1, SS2, etc., no notification (alert) is issued if the intrusion sensor response ceases within a specified grace period for alarm.

[0028] Furthermore, when switching from a security state to a non-security state, the security release guard sensor function is activated. In this case, when a legitimate user enters the security facility to switch to the non-security state, the intrusion sensor detects the intrusion and emits an alarm sound. In this case, the alarm sound also serves as a warning sound for suspicious intruders, so a loud alarm sound (threatening sound) is emitted. However, if the operation to switch from the security state to the non-security state is performed within the specified alarm grace period, no notification (alarm) is issued.

[0029] Furthermore, even when the security release guard sensor function is activated in the security device 100, if the wireless communication terminal 400 possessed by a legitimate user is connected to the security device 100 through the AP 300, no alarm sound (warning sound) is emitted. As a result, when a legitimate user who possesses the wireless communication terminal 400 enters the facility to be secured and operates the operation terminal 200 to switch the security device 100 from the security state to the non-security state, no warning sound is emitted. Therefore, the legitimate user can calmly perform the operation of switching to the non-security state without being startled or flustered by the warning sound.

[0030] In the following, a configuration example of the security device 100, the operation terminal 200, and the wireless communication terminal 400 will be described, and the details of the processing performed by the security device 100 will be described. Regarding the AP 300, since a commercially available general configuration and function access point (device) can basically be used, the description of the details of its configuration and the like will be omitted.

[0031] [Configuration Example of Security Device 100] FIG. 2 is a block diagram for explaining a configuration example of the security device 100. The connection terminal 101T constitutes a connection end portion with the wide area network 2. The communication I / F (Interface) 101 performs communication processing through the wide area network 2. That is, the communication I / F 101 converts a signal addressed to itself transmitted through the wide area network 2 into a signal in a form that can be processed by itself and captures this signal. Further, the communication I / F 101 converts a signal to be transmitted from itself to a target destination into a signal in a transmission form and sends this signal to the wide area network 2 for transmission to the destination.

[0032] The control unit 102 is a microprocessor equipped with a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), non-volatile memory, etc. (not shown), and controls each part of the security device 100. The storage device 103 is a device unit composed of a recording medium such as an SSD (Solid State Drive) and its driver, and performs recording, reading, changing, deleting, etc. of various data. The storage device 103 stores and holds necessary data and programs, and is also used as a work area for temporarily storing intermediate data generated in various processes.

[0033] The connection terminal 104T constitutes a connection end with the operation terminal 200. The operation terminal communication unit 104 functions as an interface unit with the operation terminal 200 and is a part that transmits and receives information with the operation terminal 200. That is, the operation terminal communication unit 104 receives information from the operation terminal 200, converts it into information in a format that can be processed by its own device, and supplies it to the control unit 102, etc. Also, the information to be sent from its own device is converted into a format for sending and supplied to the operation terminal 200.

[0034] The connection terminals 105T1, 105T2,... constitute connection ends with the intrusion sensors SS1, SS2,.... The sensor detection unit 105 monitors the output signals from the intrusion sensors SS1, SS2,..., and when it detects the occurrence of an intrusion, it notifies the control unit 102. Also, the sensor detection unit 105 can determine which intrusion sensor detected the occurrence of the intrusion and notify the control unit 102.

[0035] The connection terminal 106T constitutes the connection end with the AP300. The IP (Internet Protocol) communication control unit 106 enables communication with the AP300 through the LAN, and enables communication with a wireless communication terminal authenticated by the AP300 through the AP300 and the LAN. That is, the IP communication control unit 106 enables communication with a wireless communication terminal 400 etc. authenticated by the AP300 through the LAN and the AP300 through which communication is performed using the IP (Internet Protocol).

[0036] When the occurrence of an intrusion is detected through the intrusion sensors SS1, SS2,... under the control of the control unit 102, the notification processing unit 107 forms notification data for notifying the occurrence of the intrusion, and performs a process of transmitting this to the security company's security destination storage device 30. In this case, the notification data formed by the notification processing unit 107 is sent to the wide area network 2 through the communication I / F 101 and the connection terminal 101T, and is transmitted to the security destination storage device 30.

[0037] Under the control of the control unit 102, the buzzer sounding control unit 108 forms a buzzer sounding instruction and transmits it to the operation terminal 200 through the operation terminal communication unit 104 and the connection terminal 104T to sound the buzzer provided in the operation terminal 200. Also, under the control of the control unit 102, the buzzer sounding control unit 108 also performs a process of supplying voice data for emitting a buzzer sound etc. to the voice processing unit 109 so as to emit it from the speaker 110.

[0038] The voice processing unit 109 receives the supply of voice data for emitting guidance messages, buzzer sounds, etc. under the control of the control unit 102 and the buzzer sounding control unit 108, forms an analog voice signal, and supplies this to the speaker 110. The speaker 110 receives the supply of the analog voice signal from the voice processing unit 109 and emits a voice corresponding to the analog voice signal. Note that the voice processing unit 109 can adjust the volume under the control of the control unit 102 and the buzzer sounding control unit 108. Thereby, for example, during the security start guard sensor function, a message prompting departure can be emitted at an appropriate volume. Also, when an intrusion is detected through the intrusion sensors SS1, SS2, … including during the security release guard sensor function, a notification sound (intimidating sound) can be emitted at a high volume.

[0039] The AP communication unit 111 realizes the function of communicating with the AP 300 through the IP communication control unit 106, the connection terminal 106T, and further through the LAN. Therefore, the control unit 102 of the security device 100 can appropriately grasp whether there is a wireless communication terminal 400 that has been authenticated in the AP 300 and can be connected to the security device 100 by communicating with the AP 300 through the AP communication unit 111.

[0040] In the security device 100 having such a configuration, although described later, the security state and the non-security state can be switched through the operation terminal 200. That is, the control unit 102 receives a security start instruction through the connection terminal 104T and the operation terminal communication unit 104, and switches the operation state of its own device from the non-security state to the security state or from the security state to the non-security state. Note that when the control unit 102 switches the operation state of its own device from the non-security state to the security state, it operates the above-described security start guard sensor function. Also, when the operation state of its own device is in the security state and the intrusion sensor SS1, SS2, … detects the occurrence of an intrusion from the sensor detection unit 105, it operates the above-described security release guard sensor function.

[0041] Further, when the operation state of the own device is in the security state and the sensor detection unit 105 detects the occurrence of an intrusion, the control unit 102 checks whether there is a wireless communication terminal 400 that has been authenticated at the AP 300 and is connected to the own device through the AP communication unit 111. In this check, if it is confirmed that there is a wireless communication terminal 400 connected to the own device, the emission of a warning sound is suppressed. That is, the control unit 102 does not instruct the operation terminal 200 or the voice processing unit 109 to emit a warning sound through the buzzer operation control unit 108.

[0042] In addition, the control unit 102 checks whether there is a wireless communication terminal 400 connected to the own device through the AP 300. If there is no wireless communication terminal 400 connected to the own device, the control unit 102 normally controls the buzzer operation control unit 108 to execute the emission of a warning sound. In this case, when the time elapsed since the detection of the occurrence of the intrusion has passed a predetermined reporting grace period, the control unit 102 controls the reporting processing unit 107 to report to the security destination accommodation device 30 of a predetermined security company.

[0043] [Configuration example of the operation terminal 200] FIG. 3 is a block diagram for explaining a configuration example of the operation terminal 200 connected to the security device 100. The connection terminal 201T constitutes a connection end portion with the security device 100. The I / F (Interface) 201 performs communication processing with the security device 100. That is, the I / F 201 converts a signal from the security device 100 into a signal in a form that can be processed by the own device and captures it. Further, the I / F 201 converts a signal transmitted from the own device to the security device 100 into a signal in a transmission form and transmits it to the security device 100.

[0044] The control unit 202 is a microprocessor equipped with a CPU, ROM, RAM, non-volatile memory, etc. (not shown), and controls each unit of the operation terminal 200. The storage unit 203 is a device unit consisting of a recording medium such as a non-volatile memory and its driver, and records, reads, changes, deletes, etc. various data. The storage unit 203 stores and holds necessary data and programs, and is also used as a working area for temporarily storing intermediate data generated in various processes.

[0045] The operation unit 204 includes operation keys such as several function keys and numeric keys, receives operation input from the user, converts information corresponding to the received operation input into an electrical signal, and notifies the control unit 202. Therefore, by the user performing operation input through the operation unit 204, the security device 100 can be switched from a non-security state to a security state, or from a security state to a non-security state. The display unit 205 is configured, for example, with an LCD (Liquid Crystal Display), and displays various guidance messages. Specifically, the display unit 205 displays operation guidance, warning messages, messages indicating the status of the security device, and the like.

[0046] Under the control of the control unit 202, the audio processing unit 206 receives audio data for emitting a guidance message, a buzzer sound, etc., forms an analog audio signal, and supplies this to the speaker 207. The speaker 207 receives the analog audio signal from the audio processing unit 206 and emits a sound corresponding to the analog audio signal. The audio processing unit 206 is capable of adjusting the volume under the control of the control unit 202. This allows the audio processing unit 206 to emit a message encouraging the user to leave at an appropriate volume in response to an instruction from the security device 100 when the security start guard sensor function is in operation. Also, in response to an instruction from the security device 100, when an intrusion is detected through the intrusion sensors SS1, SS2, ..., including when the security release guard sensor function is in operation, an alarm sound (threatening sound) can be emitted at a high volume.

[0047] The LED unit 208 is equipped with an LED (Light Emitting Diode), and under the control of the control unit 202, displays the status of the security device 100 by turning the LED on, off, blinking, etc. That is, in response to a status notification from the security device 100, for example, when the LED is off, it indicates that the security device 10 is in a non-security status, and when the LED is on, it indicates that the security device 100 is in a security status. Also, when the security device 100 is operating a security start guard sensor function or a security release guard sensor function, it notifies the status by blinking the LED. It is also possible to provide multiple LEDs of the same color or multiple LEDs of different colors in the LED unit 208 so as to notify various statuses of the security device 100 in detail.

[0048] [Example of configuration of wireless communication terminal 400] FIG. 4 is a block diagram for explaining a configuration example of a wireless communication terminal 400 that can be connected to the security device 100 via the AP 300. The transmitting / receiving antenna 401A and the wireless communication unit 401 are parts that enable communication through a mobile phone network. The control unit 402 is a microprocessor equipped with a CPU, ROM, RAM, non-volatile memory, etc. (not shown), and controls each part of the wireless communication terminal 400. The storage unit 403 is a device unit consisting of a recording medium such as a semiconductor memory and its driver, and records, reads, changes, deletes, etc. various data. The storage unit 403 stores and holds necessary data and programs, and is also used as a working area for temporarily storing intermediate data generated in various processes.

[0049] The operation unit 404 is a part configured with a power on / off key and several function keys. The IP communication control unit 405 communicates with a neighboring AP through the short-range wireless unit 412 and the transmission / reception antenna 412A described later, and when authentication is successful, it can be connected to the LAN to which the AP is connected via the AP. The short-range wireless unit 412 and the transmission / reception antenna 412A perform wireless communication with a neighboring AP (access point) such as the AP 300 using a communication method compliant with the Wi-Fi standard under the control of the IP communication control unit 405 to obtain authentication. As a result, it becomes possible to connect to the authenticated AP and perform wireless communication.

[0050] When the wireless communication unit 401 connects a call line through the mobile phone network, the call processing unit 406 forms an analog voice signal from the voice data transmitted from the other party and supplies it to the receiver (speaker) 407 to play the voice of the other party. Also, the call processing unit 406 converts the voice (analog voice signal) of the user of the own device collected through the microphone 408 into a digital signal, and transmits this through the call line connected by the wireless communication unit 401 via the mobile phone network to the other party. In this way, the call processing unit 406 cooperates with the receiver 407 and the microphone 408 to enable a call with the other party to whom the call line is connected. The touch panel 409 is composed of, for example, a display unit 410 configured using an LCD or the like, and a touch sensor 411 provided on the display screen of the display unit 410. It provides display information to the user and receives an instruction input from the user and supplies it to the control unit 402. That is, the touch panel functions as a user interface.

[0051] In this way, the wireless communication terminal 400 can access the mobile phone network via the wireless communication unit 401 and the transceiver antenna 401A, connect a call line, and make a call. Furthermore, the wireless communication terminal 400 can communicate with a neighboring AP through the short-range wireless unit 412 and the transceiver antenna 412A, and when authentication is successful, it can connect to the LAN to which the AP is connected via the AP. In this case, the wireless communication terminal 400 can communicate with devices connected to the LAN or connect to the Internet via devices connected to the LAN to browse information and so on.

[0052] [Cooperation among the security device 100, the operation terminal 200, the AP 300, and the wireless communication terminal 400] The cooperation among the security device 100, the operation terminal 200, the wireless communication terminal 400, and the AP 300 described with reference to FIGS. 2 to 4 will be described. The switching of the security device 100 from the non-security state to the security state and the switching from the security state to the non-security state are performed through the operation terminal 200. The operation terminal 200 has a display function and an audio output function (sounding function), and can provide guidance and various notifications through display output and audio output. Therefore, even when the occurrence of an intrusion is detected through the intrusion sensors SS1, SS2, …, the sounding function of the operation terminal 200 is used to sound a warning sound (threatening sound) in response to the control from the security device 100.

[0053] The AP 300 has a general commercially available configuration and functions as described above. However, in this example, the transmission output of the AP 300 is adjusted, for example, so that communication can be performed within a range of about 5 m (meters) centered on the AP 300. The AP 300 sends out the ESSID at a predetermined timing, and performs connection authentication processing when there is a connection request in response to this. As described above, the ESSID and password of the AP 300 are set in advance in the wireless communication terminal 400. For this reason, when the wireless communication terminal 400 receives the ESSID from the AP 300 through the transceiver antenna 412A and the short-range wireless unit 412, the IP communication control unit 405 functions to send a connection request to the AP 300.

[0054] Accordingly, the AP300 requests the provision of a password for authentication. If the authentication is successful, the AP300 and the wireless communication terminal 400 communicate regularly to maintain the connection state. Such a state is grasped through the IP communication control unit 106 and the AP communication unit 111 of the security device 100. Through the AP300, the wireless communication terminal 400 is in a state of being wirelessly connected to the security device 100.

[0055] If the regular communication between the AP300 and the wireless communication terminal 400 becomes impossible, the connection state is released and re-authentication is required. In this way, when the wireless communication terminal 400 held by a legitimate user of the security device 100 approaches within a distance where wireless communication with the AP300 is possible, it is authenticated by the AP300 and automatically connected to the security device 100 via the AP300.

[0056] In the security device 100, by utilizing the cooperation with the above-mentioned various devices, when switching from the security state to the non-security state, it is possible to suppress the emission of unnecessary warning sounds (threatening sounds). Next, in the security device 100 of the security system shown in FIG. 1 configured by using the security device 100, the operation terminal 200, the wireless communication terminal 400, and the AP300 described with reference to FIGS. 2 to 4, the processing when switching from the security state to the non-security state will be specifically described.

[0057] [Processing when switching from the security state to the non-security state in the security device 100] [Example of operating the buzzer sound suppression function before detecting an intrusion] FIG. 5 is a flowchart for explaining the processing when switching from the security state to the non-security state in the security device 100, and is an example of operating the buzzer sound suppression function that suppresses the emission of the buzzer sound as a threatening sound before detecting the intrusion of the user. The processing shown in FIG. 5 is the processing during security execution executed by the control unit 102 of the security device 100 when switching from the non-security state to the security state through the operation terminal 200.

[0058] When the process shown in FIG. 5 is executed, the control unit 102 checks the state of the AP communication unit 111 and determines whether a wireless communication terminal 400 held by a legitimate user is connected through the AP 300 (step S101). In the determination process of step S101, if it is determined that the wireless communication terminal 400 is connected (there is an AP connection), the control unit 102 suppresses the buzzer sound by not instructing the buzzer sound control unit 108 (step S102). The process of step S102 is such that even if an intrusion is detected through the intrusion sensors SS1, SS2,... and the sensor detection unit 105, no instruction is given to the buzzer sound control unit 108 to prevent the emission of a warning sound (threatening sound).

[0059] Thereafter, the control unit 102 accepts a security release operation by a legitimate user through the operation terminal 200 via the connection terminal 104T and the operation terminal communication unit 104 (step S103). In step S103, for example, only a security release operation by a legitimate user is accepted by requesting the input of a password or performing fingerprint authentication through a fingerprint authentication mechanism provided in the operation terminal 200 (not shown).

[0060] Next, the control unit 102 determines whether a security release operation has been accepted through the operation terminal 200 (step S104). When it is determined in step S104 that a security release operation has been accepted, the control unit 102 controls the relevant units and transitions (switches) the operating state of the own device to a non-security state (step S105). Thereafter, the process shown in FIG. 5 is terminated.

[0061] Also, assume that it is determined in the determination process of step S104 that the security release operation has not been accepted. In this case, the control unit 102 determines whether or not a predetermined time has passed since the buzzer sound was suppressed in step S102 (whether or not a timeout has occurred) (step S106). In the security device 100 of this embodiment, if the security release operation is not performed within, for example, 30 seconds after the buzzer sound was suppressed in step S102, it is determined that a timeout has occurred.

[0062] If it is determined in the determination process of step S106 that the timeout has not occurred, the process from step S103 is repeated. If it is determined in the determination process of step S106 that the timeout has occurred, the control unit 102 determines whether the buzzer is sounding. Release suppression (Step S107), and the process from Step S101 is repeated. That is, the guard state is maintained.

[0063] Furthermore, if it is determined in the determination process of step S101 that the wireless communication terminal 400 is not connected (no AP connection), the control unit 102 determines whether or not an intrusion has been detected based on the output signal from the sensor detection unit 105 (step S108). If it is determined in the determination process of step S108 that an intrusion has not been detected, the process from step S101 is repeated. If it is determined in the determination process of step S108 that an intrusion has been detected, an intrusion response process described below is executed, and the process shown in FIG. 5 is terminated.

[0064] Fig. 6 is a flow chart for explaining the intrusion response process executed in step S109 in Fig. 5. When the intrusion response process in Fig. 6 is executed, the control unit 102 of the security device 100 first controls the buzzer sound control unit 108 to start sounding the buzzer as an alarm sound (threatening sound) (step S201). Specifically, the control unit 102 controls the buzzer sound control unit 108 to issue an instruction to the operation terminal 200 through the operation terminal communication unit 104 and the connection terminal 104T to sound the buzzer as a threatening sound. The control unit 102 also controls the buzzer sound control unit 108 to emit a buzzer sound as a threatening sound through the audio processing unit 109 and the speaker 110. This makes it possible to notify the surroundings of the occurrence of an intrusion.

[0065] Thereafter, the control unit 102 accepts a security deactivation operation by a legitimate user through the operation terminal 200 (step S202). The process of step S202 is similar to the process of step S103 in Fig. 5, and takes into consideration the case where a legitimate user who does not possess the wireless communication terminal 400 performs a security deactivation operation through the operation terminal 200. Thereafter, the control unit 102 determines whether or not a security deactivation operation has been performed by a legitimate user (step S203).

[0066] When it is determined in the determination process of step S203 that a security release operation has been performed by a legitimate user, the control unit 102 transitions the operation state of the device to a non-security state (step S204). Specifically, the process of step S204 controls the buzzer sound control unit 108 to stop the sound of the buzzer that is being emitted as an alarm sound and a threatening sound, and then switches the operation state of the device to the non-security state.

[0067] Also, assume that in the determination process of step S203, it is determined that the security release operation has not been performed by a legitimate user. In this case, in step S201, the control unit 102 determines whether or not a predetermined time has elapsed since the buzzer started sounding (whether or not a timeout has occurred) (step S205). In the determination process of this step S205, if the security release operation has not been performed within, for example, 30 seconds since the buzzer started sounding, it is determined that a timeout has occurred.

[0068] In the determination process of step S206, if it is determined that a timeout has not occurred, the process from step S202 is repeated. Also, in the determination process of step S206, if it is determined that a timeout has occurred, it is highly likely that a truly abnormal intrusion (an intrusion by someone other than a legitimate user) has occurred. In this case, the control unit 102 continues the buzzer sounding and controls the notification processing unit 107 to execute a notification process of sending a notification to a predetermined notification destination (step S206).

[0069] After transitioning to the non-security state by the process of step S204 and after performing the notification process by the process of step S206, the process of this FIG. 6 ends. Note that when the notification process is performed by the process of step S206, the buzzer sound continues to sound, but the buzzer sound can be stopped by performing a predetermined release operation by a legitimate user or a security guard.

[0070] As described above, by the process described using the flowcharts of FIGS. 5 and 6, in the security device 100, even if a legitimate user approaches the AP300 before being detected through the intrusion sensors SS1, SS2,..., the buzzer sounding is suppressed. Therefore, even if a legitimate user enters the security target facility to perform a security release operation through the operation terminal 200 and is detected through the intrusion sensors SS1, SS2,..., the warning sound (intimidating sound) is not emitted. For this reason, a legitimate user can calmly perform a security release operation through the operation terminal 200 without being startled by the emission of the warning sound (intimidating sound).

[0071] However, when a legitimate user approaches the AP300 and the buzzer sound is suppressed, if the security release operation is not performed within a certain time, the suppression of the buzzer sound is released and the security state is maintained. As a result, the security state is not released just because the legitimate user approaches the AP300, so the security function of the security device 100 is not reduced. Also, even if the user is a legitimate user, if he or she does not have the wireless communication terminal 400, a warning sound is emitted as a threatening sound as in the conventional case when the user is detected through the intrusion sensors SS1, SS2, .... Of course, if a person who does not have the wireless communication terminal 400 intrudes, a warning sound is emitted as a threatening sound as in the conventional case, and a security company is notified after a predetermined time has passed since the sound was emitted, so that the same security function as in the conventional case can be realized.

[0072] Also, if it is determined that a timeout has occurred in the determination process of step S106 in Fig. 5, there is a possibility that some kind of trouble has occurred. For this reason, if it is determined that a timeout has occurred in the determination process of step S106 in Fig. 5, it may be determined whether or not an intrusion has been detected, and if an intrusion has been detected, the intrusion response process described using Fig. 6 may be executed. Note that if it is determined that a timeout has occurred in the determination process of step S106, and an intrusion has not been detected, the process from step S101 may be repeated.

[0073] <Example of when the buzzer suppression function is activated after an intrusion is detected> The process described with reference to the flowchart of FIG. 5 is configured such that the buzzer sound suppression function operates before detecting the intrusion of a user. For this reason, when a legitimate user who possesses the wireless communication terminal 400 approaches the AP 300, the buzzer sound suppression function may be activated unnecessarily, as the buzzer sound suppression function will operate just by the user getting close. Therefore, in order to switch the operating state of the security device 100 from the security state to the non-security state, when a legitimate user enters (enters the premises) the facility to be secured and the occurrence of an intrusion is detected through the intrusion sensors SS1, SS2, …, it is considered to operate the buzzer sound suppression function.

[0074] FIG. 7 is a flowchart for explaining another example of the process when switching from the security state to the non-security state in the security device according to the embodiment, and is an example of the case where the buzzer sound suppression function is operated after detecting the intrusion of a user. The process shown in FIG. 7 is a process during security execution that is executed by the control unit 102 of the security device 100 when it is switched from the non-security state to the security state through the operation terminal 200.

[0075] When the process shown in FIG. 7 is executed, the control unit 102 determines whether or not the occurrence of an intrusion has been detected through the intrusion sensors SS1, SS2, … and the sensor detection unit 105 (step S301). If it is determined in the determination process of step S301 that the occurrence of an intrusion has not been detected, the control unit 102 repeats the process from step S301. If it is determined in the determination process of step S301 that the occurrence of an intrusion has been detected, the control unit 102 checks the state of the AP communication unit 111 and determines whether or not the wireless communication terminal 400 possessed by a legitimate user is connected through the AP 300 (step S302).

[0076] In the determination process of step S302, when it is determined that the wireless communication terminal 400 is connected (AP connected), the control unit 102 controls the buzzer sound control unit 108 to suppress the buzzer sound (step S303). The process of step S303 is such that even if an intrusion is detected through the intrusion sensors SS1, SS2, ..., an instruction is not issued to the buzzer sound control unit 108 so that a notification sound (threatening sound) is not emitted. In addition, in the determination process of step S302, when it is determined that the wireless communication terminal 400 is not connected (no AP connection), the control unit 102 controls the buzzer sound control unit 108 to sound a buzzer (step S304). In this case, since an intrusion has already been detected, a notification sound as a threatening sound is emitted at a high volume.

[0077] After the processing of step S303 or step S304, the control unit 102 accepts a security release operation by a legitimate user through the operation terminal 200 via the connection terminal 104T and the operation terminal communication unit 104 (step S305). In step S305, similar to the processing of step S103 shown in Fig. 5, a password is requested to be entered or fingerprint authentication is performed, and only a security release operation by a legitimate user is accepted.

[0078] Next, the control unit 102 determines whether or not a security release operation has been received through the operation terminal 200 (step S306). If it is determined in step S306 that a security release operation has been received, the control unit 102 controls each related unit to transition (switch) the operating state of the device to a non-security state (step S307). Note that in step S307, if a buzzer has started sounding, a process to stop the sounding is also performed. After this, the process shown in FIG. 7 ends.

[0079] Also, assume that it is determined in the determination process of step S306 that a security release operation has not been accepted. In this case, the control unit 102 determines whether a predetermined time has elapsed (whether a timeout has occurred) since the buzzer sound was suppressed in step S303 or since the buzzer sound was started in step S304 (step S308). In this example as well, the predetermined time for determining whether a timeout has occurred is, for example, 30 seconds, and if a security release operation is not performed within 30 seconds from the start of the timeout, it is determined that a timeout has occurred.

[0080] If it is determined in the determination process of step S308 that the timeout has not occurred, the process from step S305 is repeated to accept the security release operation. If it is determined in the determination process of step S308 that the timeout has occurred, in this case, the control unit 102 determines whether the buzzer has already started sounding (step S309), and if it is determined that the buzzer has not started sounding, it controls the buzzer sounding control unit 108 to start sounding the buzzer (step S310).

[0081] After step S310 and when it is determined in the determination process of step S309 that the buzzer has started to sound, a reporting process is executed (step S311). In this case, since it is highly likely that a truly abnormal intrusion has occurred, the control unit 102 continues the buzzer to sound and controls the reporting process unit 107 to execute a reporting process to report to a predetermined reporting destination. After this, the process of FIG. 7 is terminated.

[0082] Thus, in the case of the process described using the flowchart of FIG. 7, when an intrusion is detected, it becomes possible to determine whether to suppress or start the buzzer sound. This prevents the buzzer sound suppression function from operating unnecessarily. Also, if a legitimate user has the wireless communication terminal 400, the buzzer sound can be prevented from sounding and the security state can be released to a non-security state. Of course, even if a legitimate user does not have the wireless communication terminal 400, the buzzer sound is started as before, but the security state can be released to a non-security state.

[0083] <Example of the case of performing authentication of the wireless communication terminal through the AP300 after detecting an intrusion> In the process described using the flowchart of FIG. 7, the AP300 always transmits its own ESSID and accepts connection requests from neighboring wireless communication terminals, so that authentication processing can be performed at any time with the wireless communication terminal possessed by a legitimate user. However, the AP300 needs to authenticate with the wireless communication terminal 400 possessed by a legitimate user when the legitimate user enters the security target facility and switches the security device in the security state to the non-security state.

[0084] Therefore, in this example, when an intrusion is detected through the intrusion sensors SS1, SS2,... and the sensor detection unit 105, an instruction is issued from the security device 100 to the AP300 to execute an authentication process to authenticate with the wireless communication terminal 400. If authentication is successful through this authentication process, the buzzer sound suppression function is operated. Of course, if authentication fails, the buzzer sound is not suppressed and normal countermeasures are taken. In the case of this example, since the AP300 only needs to function when an intrusion is detected, the AP300 does not need to always send out the ESSID and prepare for authentication processing, and does not perform unnecessary authentication processing, which can contribute to improving the reliability of the security system.

[0085] FIG. 8 is a flowchart for explaining another example of the process when switching from the security state to the non-security state in the security device according to the embodiment, and is an example when authentication of the wireless communication terminal is taken through the AP 300 after detecting an intrusion. In the flowchart of FIG. 8, steps in which the same processing as in the flowchart of FIG. 7 is performed are denoted by the same reference numerals, and detailed description of those steps is omitted. As can be seen by comparing the flowchart of FIG. 8 with the flowchart of FIG. 7, in the case of the processing shown in the flowchart of FIG. 8, the processing of step S401 is increased.

[0086] That is, when the process shown in FIG. 8 is executed, the control unit 102 determines whether or not an intrusion has occurred through the intrusion sensors SS1, SS2,... and the sensor detection unit 105 (step S301). In the determination process of step S301, if it is determined that an intrusion has not occurred, the control unit 102 repeats the process from step S301. In the determination process of step S301, if it is determined that an intrusion has occurred, the control unit 102 controls the AP communication unit 111 and instructs the AP 300 to execute an authentication process through the IP communication control unit 106 and the connection terminal 106T (step S401).

[0087] Thereby, the AP 300 sends out the ESSID, requests the wireless communication terminal that has sent a connection request to provide a password, and if the password is provided from the wireless communication terminal and the password is correct, authenticates the connection of the wireless communication terminal. Thereby, the wireless communication terminal is made to connect to the security device 100 through the AP 300. After the processing of step S401, the same processing as the processing described using the flowchart of FIG. 7 is performed (steps S302 to S311).

[0088] As described above, in the case of the processing shown in the flowchart of FIG. 8, after detecting the occurrence of an intrusion, an instruction to execute an authentication process is given to the AP 300, so that the AP 300 does not execute an unnecessary authentication process. Thereby, the reliability of the security system configured using the security device 100 can be improved.

[0089] Of course, in the case of the process shown in FIG. 8, as in the case of the process shown in FIG. 7, when the occurrence of an intrusion is detected, it becomes possible to determine whether to suppress or start the buzzer sound. This prevents the buzzer sound suppression function from operating unnecessarily. Also, if a legitimate user possesses the wireless communication terminal 400, the buzzer sound can be prevented from occurring and the security state can be released to a non-security state. Of course, if a legitimate user does not possess the wireless communication terminal 400, the buzzer sound will be started as before, but the security state can be released to a non-security state.

[0090] <Enhancement of the security strength of the authentication process for connectable wireless communication terminals> The process described with reference to the flowcharts of FIGS. 5 to 8 enables the wireless communication terminal 400 that has been authenticated using the authentication function of the AP 300 to be connected to the security device 100 through the AP 300. However, because the authentication function of the AP 300 is used, the connection of the wireless communication terminal 400 is enabled only by a general-purpose authentication process using the ESSID and password set in the AP 300. For this reason, it is also conceivable to increase the security strength. The example described below is one in which the security strength of the authentication process for connectable wireless communication terminals is made higher. For this reason, some configuration changes occur to the security device 100 and the wireless communication terminal 400 described above.

[0091] <<Configuration example of security device 100A (another example of security device)>> FIG. 9 is a block diagram for explaining another configuration example of the security device, and is a block diagram for explaining a configuration example of the security device 100A having a configuration for increasing the security strength of the authentication process for connectable wireless communication terminals. In FIG. 9, parts having the same configuration as the security device 100 shown in FIG. 2 are given the same reference numerals, and detailed descriptions of those parts are omitted because they are repetitive.

[0092] As can be seen by comparing FIG. 9 and FIG. 2, the security device 100A in this example is different from the security device 100 shown in FIG. 2 in that it includes a general-purpose terminal communication unit 112. The general-purpose terminal communication unit 112 communicates with a wireless communication terminal that has been authenticated with the AP 300 and can be connected to the security device 100A under the control of the control unit 102, through the IP communication control unit 106 and the connection terminal 106T, and further through the AP 300.

[0093] Specifically, the general-purpose terminal communication unit 112 acquires predetermined authentication information previously set in the wireless communication terminal 400A, which is transmitted from the wireless communication terminal 400A wirelessly connected to the security device 100A through the AP 300. As a result, in the security device 100A, it becomes possible to determine whether the authentication information provided from the wireless communication terminal wirelessly connected through the AP 300 is appropriate authentication information set in advance. That is, the authentication information provided from the wireless communication terminal enables a final determination as to whether the wireless communication terminal can truly be connected to the security device 100A.

[0094] <<Configuration Example of Wireless Communication Terminal 400A (Another Example of Wireless Communication Terminal)>> FIG. 10 is a block diagram for explaining another configuration example of a wireless communication terminal, and is a block diagram for explaining a configuration example of a wireless communication terminal 400A having a configuration for increasing the security strength of the authentication process of a connectable wireless communication terminal. In FIG. 10, parts having the same configuration as the wireless communication terminal 400 shown in FIG. 4 are denoted by the same reference numerals, and detailed descriptions thereof are omitted because they are redundant.

[0095] As can be seen by comparing FIG. 10 and FIG. 4, the wireless communication terminal 400A in this example is different from the wireless communication terminal 400 shown in FIG. 4 in that it includes a security device communication unit 413. The security device communication unit 413 communicates with the security device 100A that has been authenticated with the AP 300 and can be connected under the control of the control unit 402, through the short-range wireless unit 412 and the transmission / reception antenna 412A, and further through the AP 300.

[0096] Specifically, when the security device communication unit 413 is authenticated through the AP300 and connected to the security device 100A through the AP300, it transmits predetermined authentication information that has been set in advance to the security device 100A. As described above, the authentication information is set in advance for the wireless communication terminal 400A held by a legitimate user of the security device 100A. The authentication information is transmitted to the security device 100A through the short-range wireless unit 412, the transmission / reception antenna, and further through the AP300.

[0097] <<Another example of the process when switching from the security state to the non-security state>> FIG. 11 is a flowchart for explaining the process when switching from the security state to the non-security state, which is executed in the security device 100A having the configuration shown in FIG. 9. In the flowchart of FIG. 11, steps where the same processing as in the flowchart of FIG. 7 is performed are assigned the same reference numerals, and detailed explanations of these steps are omitted. As can be seen by comparing the flowchart of FIG. 11 and the flowchart of FIG. 7, in the flowchart of FIG. 11, the processing of steps S501, S502, and S503 is increased, and the difference lies in the fact that security is enhanced using authentication information.

[0098] The processing of the flowchart shown in FIG. 11 is executed in the control unit 102 of the security device 100A. When the processing shown in FIG. 11 is executed, the control unit 102 determines whether an intrusion has occurred through the intrusion sensors SS1, SS2,... and the sensor detection unit 105 (step S301). In the determination process of step S301, if it is determined that an intrusion has not occurred, the control unit 102 repeats the processing from step S301.

[0099] In the determination process of step S301, when it is determined that the occurrence of an intrusion has been detected, the control unit 102 controls the AP communication unit 111 to instruct the AP 300 to execute an authentication process through the IP communication control unit 106 and the connection terminal 106T (step S501). As a result, the AP 300 sends out the ESSID, requests the provision of a password from the wireless communication terminal that has sent a connection request, and if the password is provided from the wireless communication terminal and the password is correct, authenticates the connection of the wireless communication terminal. As a result, the wireless communication terminal is made to connect to the security device 100A through the AP 300.

[0100] Next, the control unit 102 checks the state of the AP communication unit 111 and determines whether a wireless communication terminal 400 possessed by a legitimate user is connected through the AP 300 (step S302). Assume that in the determination process of step S302, it is determined that the wireless communication terminal 400 is connected (there is an AP connection). In this case, the general-purpose terminal communication unit 112 is controlled to acquire the authentication information transmitted from the wireless communication terminal 400A (step S502). In this example, as described above, the wireless communication terminal 400A that has been authenticated by the AP 300 and can be connected to the security device 100A through the AP 300 is configured to transmit preset predetermined authentication information to the security device 100A.

[0101] After that, the control unit 102 determines whether the authentication information can be acquired from the wireless communication terminal 400A in step S502 and whether the authentication information is legitimate (step S503). Assume that in the determination process of step S503, it is determined that legitimate authentication information has been acquired (authentication is OK). In this case, the control unit 102 controls the buzzer sounding control unit 108 to operate the buzzer sounding suppression function (step S303). The process of step S303 is to prevent the buzzer sounding control unit 108 from emitting a notification sound (scaring sound) even if an intrusion is detected through the intrusion sensors SS1, SS2,....

[0102] Also, in the determination process of step S302, if it is determined that the wireless communication terminal 400A is not connected (no AP connection), and in the determination process of step S503, if it is determined that the authentication is not OK, the buzzer is started to sound (step S304). In step S304, the control unit 102 controls the buzzer sound control unit 108 to start emitting a warning sound (threat sound) through the operation terminal 200, the audio processing unit 109, and the speaker 110 to notify the occurrence of an intrusion. The subsequent processing will be the same as the processing of steps S305 to S311 described with reference to FIG. 7.

[0103] In this way, in this example, not only the authentication process by the AP 300 but also whether the security device 100A and the wireless communication terminal 400A can directly communicate and obtain predetermined authentication information can determine the operation / non-operation of the buzzer sound function. As a result, only when it is detected that an intrusion has occurred in the security target facility, the authentication by the AP 300 is successful, and further, appropriate authentication information can be obtained from the wireless communication terminal 400A, the security device 100A can use the buzzer sound suppression function. Therefore, the security strength of the authentication process for connectable wireless communication terminals can be increased, and the buzzer sound suppression function can be used only when it is truly necessary.

[0104] <Summary of the processing performed in the security system> Next, the processing performed in the security system configured as shown in FIG. 1 using the security device 100A shown in FIG. 9, the wireless communication terminal 400A shown in FIG. 10, and the AP 300 will be summarized with reference to the sequences of FIGS. 12 and 13.

[0105] <<When the buzzer sound suppression function operates>> FIG. 12 is a sequence diagram for explaining the processing in a security system configured using the security device 100A shown in FIG. 9 and the wireless communication terminal 400A shown in FIG. 10, and is an example when the buzzer sound suppression function operates. For the security device 100A, as also shown in FIG. 9, the AP 300 is connected through the IP communication control unit 106 and the connection terminal 106T, and communication is possible with the AP 300 (step S0). When the intrusion sensor SS1 or the like senses (detects) the occurrence of an intrusion (step S1), the output signal from the intrusion sensor SS1 or the like is supplied to the sensor detection unit 105, so the occurrence of an intrusion is detected in the sensor detection unit 105 (step S2).

[0106] Since the sensor detection unit 105 notifies the control unit 102 of the occurrence of an intrusion, under the control of the control unit 102, the AP communication unit 111 functions to send an authentication request to the AP 300 (step S3). The authentication request is sent to the AP 300 through the IP communication control unit 106 (step S4). In response to the authentication request, the AP 300 sends necessary information such as the ESSID to the surrounding wireless communication terminals 400A to notify of its own presence (step S5). In response to this, the short-range wireless unit 412 of the wireless communication terminal 400A sends a connection request to the AP 300 under the control of the IP communication control unit 405, provides necessary information such as a password (described as PW in FIG. 12), etc. (step S6), and tries to receive authentication.

[0107] In this example, the wireless communication terminal 400A is possessed by a legitimate user, and necessary Information information such as the ESSID and password of the AP 300 are preset. Therefore, since the wireless communication terminal 400A can provide necessary information such as the password to the AP 300, authentication is successful, and the AP 300 and the wireless communication terminal 400A are wirelessly connected. As a result, the wireless communication terminal 400A is connected to the security device 100A via the AP 300 (step S7). The security device 100A also grasps that the wireless communication terminal 400A is connected to itself through the AP communication unit 111.

[0108] Next, in the wireless communication terminal 400A connected to the security device 100A, the security device communication unit 413 functions to transmit predetermined authentication information set in advance to the security device 100A (step S8). The authentication information is transmitted to the security device 100A through the short-range wireless unit, the transmission / reception antenna 412A, and further the AP 300 under the control of the IP communication control unit 405 (step S9).

[0109] In the security device 100A, the connection terminal 106T, the IP communication control unit 106, and further the general-purpose terminal communication unit 112 function to receive and hold the authentication information from the wireless communication terminal 400A (step S10). The general-purpose terminal communication unit 112 determines whether the authentication information has been received or, if received, whether the authentication information is appropriate under the control of the control unit 102 (step S11). In the determination process of step S11, if it can be determined that the authentication information is appropriate predetermined authentication information, it is notified to the sensor detection unit 105 through the control unit 102 that the authentication is OK (step S12). As a result, the sensor detection unit 105 can, through the control unit 102, prevent the buzzer sound control unit 108 from giving a buzzer sound instruction. That is, the buzzer sound is suppressed (step S13).

[0110] <<When the buzzer sound suppression function operates>> FIG. 13 is a sequence diagram for explaining the processing in a security system configured using the security device shown in FIG. 9 and the wireless communication terminal shown in FIG. 10, and is an example when the buzzer sound suppression function does not operate. In FIG. 13, the same reference numerals are given to the sequences (steps) in which the same processing as in the sequence diagram shown in FIG. 12 is performed, and the detailed description of that part is omitted. As can be seen by comparing FIG. 13 and FIG. 12, the processing from step S0 to step S11 is performed in the same manner.

[0111] That is, even in the case of the process shown in the sequence diagram of FIG. 13, in the process of step S11, the general-purpose terminal communication unit 112 determines whether it has received authentication information or, if received, whether the authentication information is appropriate under the control of the control unit 102 (step S11). Suppose that in the determination process of step S11, it is determined that the authentication information has not been received or that the received authentication information is not appropriate. In this case, the general-purpose terminal communication unit 112 notifies the sensor detection unit 105 that the authentication has failed through the control unit 102 (step S21). As a result, the sensor detection unit 105 issues an instruction to the buzzer sounding control unit 108 through the control unit 102 to start buzzer sounding (step S22).

[0112] As a result, the buzzer sounding control unit 108 requests the operation terminal 200 to emit a notification sound (threat sound) for notifying the occurrence of an intrusion through the operation terminal communication unit 104 and the connection terminal 104T (step S23). At the same time, the buzzer sounding control unit 108 provides buzzer sound data to the audio processing unit 109 through the control unit 102 and controls it to emit a notification sound (threat sound) for notifying the occurrence of an intrusion (step S24). As a result, a notification sound (threat sound) for notifying the occurrence of an intrusion can be emitted from the operation terminal 200 and the speaker 110.

[0113] As described above, in the case of the example described with reference to FIGS. 9 to 13, in addition to the authentication process for normal Wi-Fi (registered trademark) connection in the AP 300, the security device 100A can perform an authentication process based on the authentication information from the wireless communication terminal 400A. Such two-stage authentication increases the security strength of the authentication process of the connectable wireless communication terminal, and the buzzer sound suppression function can be used only when it is truly necessary.

[0114] [Effects of the Embodiment] The security devices 100 and 100A of the above-described embodiment are such that legitimate users are Alarm state from Non-alarm stateWhen switching, an alarm sound (scaring sound) for notifying the occurrence of an intruder can be suppressed without much effort and without being noticed by legitimate users. As a result, legitimate users Alarm state from Non-alarm state When switching, an alarm sound (scaring sound) for notifying the occurrence of an intruder is not emitted. Therefore, the alarm sound can prevent people from being startled, the sound from being annoying and causing a psychological burden, or taking time to switch due to anxiety. Therefore, Alarm state from Non-alarm state When switching, it is possible to eliminate the nuisance caused by the emission of a high-volume alarm sound (scaring sound).

[0115] In addition, by combining the emission of the alarm sound when the sensor detects and authentication using general-purpose terminals (general-purpose devices) such as wireless communication terminals 400 and 400A, it is possible to improve the usability and reliability of the security system. That is, it is possible to prevent the emission of unnecessary scaring sounds and unnecessary notifications, so that it functions stably. When a truly abnormal intrusion occurs, an alarm sound (scaring sound) can be immediately emitted, so that a reliable security system can be constructed.

[0116] [Modification Example] In the above-described embodiment, when the occurrence of an intrusion is detected, an alarm sound (scaring sound) is immediately emitted. However, the present invention is not limited to this. For example, for a certain period of time after the detection of an intrusion, an alarm sound (warning sound) for notifying the occurrence of an intrusion, which is not a very loud sound, is notified, and after a certain period of time has elapsed, a high-volume alarm sound (scaring sound) can be notified. Even in this case, the present invention can be applied and the emission of the first alarm sound (warning sound) can be suppressed. Even in this case, legitimate users can perform the switching operation to the non-security state without being flustered.

[0117] In the above-described embodiment, operating the buzzer sound suppression function means not emitting the buzzer sound as an alarm sound (scaring sound). However, the present invention is not limited to this. For example, when the buzzer sound suppression function is operated, the volume of the buzzer sound can be lowered or at an appropriate volume Non-alarm stateIt is also possible to emit an audio message that prompts a switching operation.

[0118] Also, in the security devices 100 and 100A of the above-described embodiments, each unit is controlled via the control unit 102, but it is not limited to this. Thing For example, when the sensor detection unit 105 detects the occurrence of an intrusion, the sensor detection unit 105 can directly issue a sounding instruction to the buzzer sounding control unit 108.

[0119] Also, the communicable distance between the AP 300 and the wireless communication terminals 400 and 400A can be set to an appropriate distance by taking measures such as adjusting the transmission output of the AP 300.

[0120] [Others] As can be understood from the description of the above-described embodiments, the function of the sensor detection means in the claims is realized by the sensor detection unit 105 of the security devices 100 and 100A in the embodiments. Also, the function of the notification control means in the claims is mainly realized by the buzzer sounding control unit 108 of the security devices 100 and 100A. Also, the function of the operation state switching means in the claims is mainly realized by the control unit 102 of the security devices 100 and 100A. Also, the function of the base station communication means in the claims is realized by the cooperation of the AP communication unit 111 and the IP communication control unit 106 of the security devices 100 and 100A.

The function of the authentication information acquisition means in the claims is mainly realized by the general-purpose terminal communication unit 112 of the security devices 100 and 100A.

[0121] Also, the functions of the IP communication control unit 106, the buzzer sounding control unit 108, and the AP communication unit 111 of the security devices 100 and 100A can also be realized as functions of the control unit 102 by a program executed by the control unit 102.
