Description

[Technical Field]

[0001] The present invention relates to a security device, a security system, and a program. [Background technology]

[0002] Recently, there is a technology known that detects a fall by a wearable device such as a smartwatch based on acceleration and other data measured by the device, and prompts the wearer to contact emergency services such as 119. This technology can respond to injuries and loss of consciousness caused by a fall, leading to the saving of lives.

[0003] As a technology for detecting and notifying such falls, a technology has been disclosed in which an impact is detected, and a first motion characteristic before the impact and a second motion characteristic after the impact are determined, thereby determining that the user has fallen and notifying the user that the user has fallen (for example, Patent Document 1).

[0004] In addition, in the past, when a security device such as a home security system is installed inside a facility, a technology has been known in which an exit timer is activated to delay the security set for a predetermined period of time after the security set operation is performed on the security device, so as to prevent false alarms from occurring until the person leaving the facility has completely left.

[0005] Furthermore, in the past, when a security device such as a home security system is installed inside a facility, a technology has been known in which the security device guarding the facility activates an entry timer that delays the transmission of an alarm by a sensor installed at the entrance / exit for a predetermined period of time after detecting an entrant using a sensor installed at the entrance / exit, so as to prevent false alarms from occurring between the time the entrant performs the operation to deactivate the security system.

[0006] [Patent Document 1] Special Publication No. 2020-531110 Summary of the Invention [Problem to be solved by the invention]

[0007] However, if, for example, a person leaving the facility falls at the entrance of the facility while the exit timer is running and is unable to leave, causing the timer to run out, there is a risk of a false alarm being issued.

[0008] Furthermore, for example, if a visitor falls at the entrance to the facility while the entrance timer is running and is unable to deactivate the security, causing the entrance timer to time out, there is a risk of a false alarm being issued.

[0009] The present invention has been made in consideration of the above, and aims to suppress false alarms when a person leaving the building falls while the exit timer is operating and is unable to leave, and when a person entering the building falls while the entry timer is operating and is unable to release the security. [Means for solving the problem]

[0010] In order to solve the above-mentioned problems and achieve the object, the present invention provides a security device that starts security after timing a predetermined time for starting security when it receives a command input from a user to start security, and that is equipped with a security cancellation unit that cancels the start of security by stopping timing of the predetermined time for starting security when it detects a fall of the user based on a fall detection signal received from a mobile terminal carried by the user after it receives a command input from the user to start security but before the predetermined time for starting security has elapsed.

[0011] In addition, in order to solve the above-mentioned problems and achieve the object, the present invention provides a timer unit that, when a user's entry into a facility is detected while security has been initiated, times a predetermined time for accepting an instruction to deactivate security from the user, and deactivates security if the instruction is accepted from the user before the predetermined time has elapsed; and if the timer unit detects a fall by the user based on a fall detection signal received from a mobile terminal carried by the user before the predetermined time has elapsed, it extends the predetermined time. [Effects of the Invention]

[0012] According to the present invention, it is possible to suppress false alarms when a person leaving the building falls while the exit timer is operating and is unable to leave, and when a person entering the building falls while the entry timer is operating and is unable to release the security.

[0014] Below, with reference to the drawings, embodiments of a security device, a security system, and a program according to the present invention will be described in detail. Furthermore, the present invention is not limited to the following embodiments, and the components in the following embodiments include those that would be easily conceived by a person skilled in the art, those that are substantially the same, and those that are within the scope of what is called equivalents. Furthermore, various omissions, substitutions, modifications, and combinations of the components can be made without departing from the spirit of the following embodiments.

[0015] (First embodiment) (Overall configuration of security system) 1 is a diagram showing an example of the overall configuration of a security system 1 according to the first embodiment. The overall configuration of the security system 1 according to the present embodiment will be described with reference to FIG.

[0016] 1, the security system 1 includes a security device 10, a wearable device 11 which is a mobile terminal, a monitoring device 20, and a mobile phone 30. The security device 10 is installed at the location to be guarded, and the monitoring device 20 is installed in a monitoring center.

[0017] The security device 10, the monitoring device 20, and the mobile phone 30 can communicate data via a network N1. The network N1 is configured by the Internet, a LAN (Local Area Network), or a combination of these, and may include either a wired network or a wireless network.

[0018] The security device 10 detects an intruder into a monitored area of ​​a security location and transmits an intrusion alarm to the monitoring device 20. The security device 10 also detects when a user 40 falls.

[0019] The security device 10 includes sensors 50a to 50n, which are a plurality of intrusion detection means installed in a monitored area, and an operating device 60.

[0020] The sensors 50a to 50n are various sensors that detect people who may be intruders into the monitored area (hereinafter simply referred to as "intruders"), such as infrared sensors that detect people based on changes in the amount of received infrared light, blocking sensors that detect people when infrared light or the like is blocked, presence sensors that detect people by disturbances in electromagnetic waves, magnet sensors that detect the opening and closing of doors using magnets, and image sensors that detect people or their suspicious behavior by image recognition of images captured by a camera. Each sensor transmits a detection signal to the security device 10.

[0021] The controller 60 is equipped with an LCD screen and operation buttons for displaying various setting screens, etc., and is a security mode switching means that displays an initial setting screen and a security mode setting screen on the LCD screen and allows the user 40 to input initial settings for the security device 10 and various security mode settings for the security device 10. The controller 60 transmits instructions to the security device 10 according to the received input. Here, the security mode is a mode that determines the operation of the security device 10, such as whether to report the detection of an intruder to a reporting destination such as the monitoring device 20 at the monitoring center when an intruder is detected in the monitored area. Specifically, there are a security status mode and a security status mode. The controller 60 may be built into the security device 10 or installed externally to the security device 10.

[0022] The security mode is a state in which, when sensors 50a to 50n detect an intruder and transmit a detection signal, the security device 10 that receives the detection signal sends an intrusion alarm to the monitoring device 20 in the monitoring center to notify that an intruder has been detected.

[0023] The security-off state mode is a security mode in which, when sensors 50a to 50n detect an intruder and transmit a detection signal, even if the security device 10 receives the detection signal, it does not report it to the monitoring device 20 in the monitoring center.

[0024] Each of these states is set by the user 40 operating the operation device 60.

[0025] When the operator 60 receives an operation by the user 40 to switch from the security release mode to the security mode (an operation to set security; an input command to start security) while the security device 10 is in the security release mode, the security device 10 activates an exit timer that delays the security setting for a predetermined time so as to prevent false alarms from occurring until the user 40 has completely left the premises. After the predetermined time has elapsed, the security device 10 switches from the security release mode to the security mode and transmits a security start signal to the monitoring device 20 together with a security device ID for identifying itself. When the monitoring device 20 receives the security start signal together with the security device ID from the security device 10, it begins monitoring the monitoring area of ​​the security device 10 corresponding to the security device ID, and waits to receive various alarms from the security device 10, including a report that an intruder has been detected.

[0026] Here, the security device 10 may be configured to immediately activate an exit timer when the operator 60 accepts an operation by the user 40 to set security, but the wearable device 11 or any other mobile terminal carried by the user 40 may hold identification information that identifies itself (the wearable device 11 or mobile terminal) or the user 40 himself, and transmit the identification information to the security device 10 or the operator 60 via short-range wireless communication standards such as Bluetooth or UWB (Ultra Wide Band), and the security device 10 or the operator 60 may receive and authenticate the identification information, and instead of the above-mentioned operation to set security, the security device 10 may start the exit timer if authentication based on the identification information received by the security device 10 or the operator 60 is successful after the operator 60 accepts an operation by the user 40 to set security.

[0027] Furthermore, when the security device 10 receives a detection signal from a sensor 50n installed at the entrance / exit of the facility in the security mode indicating that a user 40 has been detected entering the facility, the security device 10 activates an entry timer that delays the transmission of an alarm in response to the detection signal for a predetermined time until the operator 60 receives an operation by the user 40 to switch the security mode to the security release mode (an operation to release security). If the operator 60 receives an operation by the user 40 to switch the security mode to the security release mode (an operation to release security; an input of an instruction to release security) within that predetermined time, the security device 10 switches from the security mode to the security release mode and transmits a security release signal together with the security device ID to the monitoring device 20. When the monitoring device 20 receives the security release signal together with the security device ID from the security device 10, it ends monitoring of the monitoring area of ​​the security device 10 corresponding to the security device ID.

[0028] Here, the security device 10 may be configured to switch from the security status mode to the security disengagement status mode after the entry timer is activated and the operating device 60 receives an operation from the user 40 to deactivate the security, but the wearable device 11 or any other mobile terminal carried by the user 40 may hold identification information that identifies itself (the wearable device 11 or mobile terminal) or the user 40 himself, and transmit the identification information to the security device 10 or the operating device 60 via short-range wireless communication standards such as Bluetooth or UWB (Ultra Wide Band), and the security device 10 or the operating device 60 may receive the identification information, and instead of the aforementioned operation to deactivate the security, the security device 10 may be configured to switch from the security status mode to the security disengagement status mode after the security device 10 activates the entry timer and if authentication based on the identification information received by the security device 10 or the operating device 60 is successful.

[0029] Furthermore, when the sensors 50a to 50n detect an intruder, the security device 10, provided that the security device is in security mode, transmits an intrusion alarm to the monitoring device 20 from the other sensors immediately after a predetermined time has elapsed on the entrance timer if the sensor 50n installed at the entrance detects an intruder. More specifically, the security device 10 transmits its own identification information, the security device ID, to the monitoring device 20 along with the intrusion alarm.

[0030] Additionally, the security device 10 detects a fall of the user 40 based on a signal received from the wearable device 11. The security device 10 detects a fall of the user 40 by receiving a fall-related information signal (fall detection signal) including information related to the fall of the user 40, which is transmitted by the wearable device 11. After detecting a fall of the user 40, if the security device 10 confirms that something abnormal has occurred with the user 40, it transmits an alert to the monitoring device 20 in the monitoring center via the network N1.

[0031] Wearable device 11 is a device that is worn on the body of user 40 and can detect a fall of user 40. When wearable device 11 detects a fall of user 40, it transmits (outputs) a fall-related information signal indicating that a fall of user 40 has been detected to security device 10 via wireless communication. Wearable device 11 also detects acceleration information using, for example, an acceleration sensor, or angular velocity information using a gyro sensor, or detects vital data, which is biological information of user 40, such as body temperature, heart rate, or electrocardiogram, and outputs the acceleration information, angular velocity information, or vital data as a fall-related information signal. Wearable device 11 may be, for example, a so-called smart watch that can detect the acceleration information, angular velocity information, or vital data described above, or may be a vital sensor or the like that can detect the vital data described above.

[0032] In addition, the wearable device 11 may output a signal directly indicating that a fall by the user 40 has been detected as a fall-related information signal, or may output acceleration information or angular velocity information or vital data indicating the state of the user 40 as a fall-related information signal, and the security device 10 may detect a fall by the user 40 by analyzing the contents of the fall-related information signal.

[0033] Furthermore, the wearable device 11 may transmit a fall-related information signal to an information terminal such as a smartphone on which a predetermined app is installed via short-range wireless communication such as Bluetooth (registered trademark), and the information terminal may then transmit the fall-related information signal to the security device 10 via the network N1. Furthermore, the information terminal may detect a fall of the user 40 by analyzing the fall-related information signal received from the wearable device 11, and transmit a signal directly indicating that a fall of the user 40 has been detected to the security device 10 as the fall-related information signal. Furthermore, the information terminal may be carried by the user 40 together with the wearable device 11.

[0034] The monitoring device 20 is an information processing system for executing predetermined measures in response to an alarm received from the security device 10. For example, when the monitoring device 20 receives an intrusion alarm from the security device 10, it transmits a message via the network N1 to a mobile phone 30 carried by a member of the team in charge of managing and overseeing the above-mentioned monitored area, instructing them to rush to the monitored area. The monitoring device 20 also notifies relevant organizations such as the police and fire department as necessary.

[0035] When the monitoring device 20 receives an alarm, it is not limited to sending a message to the mobile phone 30 of the team member who manages and is in charge of the monitored area, but may also send a message to the mobile phone of, for example, a close relative such as a family member or relative of the user 40, or a person who has been notified in advance. In this case, if the mobile phone of the close relative or person who has been notified in advance cannot be contacted, a message instructing the team member who manages and is in charge of the monitored area to rush to the monitored area may be sent via the network N1 to the mobile phone 30 carried by the team member.

[0036] The mobile phone 30 is a mobile phone such as a smartphone carried by a member of the team who manages and is in charge of the monitoring area of ​​the user 40 described above.

[0037] (Hardware configuration of security device 10) 2 is a diagram showing an example of the hardware configuration of the security device 10. With reference to FIG. 2, the hardware configuration of the security device 10 according to the present embodiment will be described.

[0038] As shown in Figure 2, the security device 10 includes a CPU (Central Processing Unit) 501, a ROM (Read Only Memory) 502, a RAM (Random Access Memory) 503, a storage device 504, a wireless communication circuit 511 (receiving unit), an antenna 511a, a communication circuit 512, an operator 60, and a sensor input circuit 513.

[0039] The CPU 501 is a computing device that controls the overall operation of the security device 10. The ROM 502 is a non-volatile storage device that stores programs used to drive the CPU 501. The RAM 503 is a volatile storage device that is used as a work area for the CPU 501.

[0040] The storage device 504 is a non-volatile storage device such as an EEPROM (Electrically Erasable Programmable Read Only Memory) or a flash memory that stores programs and various data.

[0041] The wireless communication circuit 511 is a communication circuit that performs wireless communication with other devices such as the monitoring device 20 via the antenna 511a and the network N1 in accordance with standards such as Wi-Fi, 4G, or 5G.

[0042] The communication circuit 512 is a communication circuit for performing data communication with the wearable device 11 in accordance with standards such as NFC (Near Field Communication), Bluetooth, or UWB (Ultra Wide Band). Note that when the communication circuit 512 performs data communication with the wearable device 11, it is not limited to wireless communication and may also use wired communication.

[0043] The controller 60 includes a speaker, which is a built-in audio device that converts electrical signals into physical vibrations and outputs sounds such as music or voice. The controller 60 includes a display unit such as various indicator lamps, LEDs (Light Emitting Diodes), or a display. The controller 60 includes an operation unit such as various buttons or a touch panel for operation by users including the user 40. The controller 60 may be built into the security device 10 or may be installed externally to the security device 10.

[0044] The sensor input circuit 513 is a circuit for receiving input of detection signals from the sensors 50a to 50n. Note that when the sensor input circuit 513 communicates data with the sensors 50a to 50n, it is not limited to wireless communication, and wired communication may also be used.

[0045] The above-mentioned CPU 501, ROM 502, RAM 503, storage device 504, wireless communication circuit 511, communication circuit 512, controller 60, and sensor input circuit 513 are communicably connected to one another via a bus 510 such as an address bus and a data bus.

[0046] The hardware configuration of the security device 10 shown in FIG. 2 is an example, and it is not necessary for all of the components to be included, and other components may also be included.

[0047] The program executed by the security device 10 of this embodiment is provided as a file in an installable or executable format recorded on a computer-readable recording medium such as a CD-ROM, a flexible disk (FD), a CD-R, or a DVD (Digital Versatile Disc).

[0048] The program executed by the security device 10 of this embodiment may be stored on a computer connected to a network such as the Internet and provided by being downloaded via the network. The program executed by the security device 10 of this embodiment may be provided or distributed via a network such as the Internet.

[0049] The program executed by the security device 10 of this embodiment may be provided by being pre-installed in a ROM or the like.

[0050] (Problems with conventional security systems) Here, we will explain the problems that arise in conventional security systems when a user 40 leaving the building switches from security-off mode to security-on mode (an operation to set security), and when a user 40 entering the building switches from security-on mode to security-off mode (an operation to release security).

[0051] A user 40 leaving the facility uses the operating device 60 to switch from security-off mode to security-on mode (to set security), but if the security device 10 is installed inside the facility and immediately switches to security mode after this operation, the sensors 50a-50n will detect the user 40 and a false intrusion alarm will be sent to the monitoring device 20. Therefore, to prevent a false alarm from occurring until the user 40 has completely left the monitored area, when the security device 10 receives the operation to set security, it activates an exit timer that delays the security setting for a predetermined period of time.

[0052] Here, a situation may occur in which the user 40 leaving the facility falls while leaving the monitored area within the predetermined time period during which the exit timer is activated.

[0053] However, once the predetermined time has elapsed, the security device 10 starts guarding and notifies the monitoring device 20 of this.

[0054] Furthermore, it is possible that the user 40 who has fallen may stand up and try to leave the monitored area after a predetermined time has passed. In this case, the sensors 50a to 50n will detect the user 40, and the security device 10 will send a false intrusion alarm to the monitoring device 20.

[0055] Meanwhile, the user 40 entering the facility will use the operating device 60 to switch from the security mode to the security release mode (to release the security), but if the security device 10 is installed inside the facility, the sensor 50n installed at the entrance will detect the entering user 40 before this operation, and a false intrusion alarm will be sent to the monitoring device 20. Therefore, in conventional security systems, in the security mode, the security device 10 will operate an entry timer that delays the transmission of the intrusion alarm detected by the sensor installed at the entrance for a predetermined time, so as to prevent a false alarm from occurring until the entering user 40 has completed the operation to release the security.

[0056] Here, a situation may occur in which a user 40 entering the facility falls within the monitored area before completing the operation to release the security within the predetermined time period while the entrance timer is running.

[0057] However, once the predetermined time has elapsed, the security device 10 issues an intrusion alarm to the monitoring device 20.

[0058] Furthermore, the fallen user 40 may stand up after a predetermined time has passed and attempt to cancel the security. In this case, the sensors 50a to 50n may detect the user 40, and the security device 10 may send a false intrusion alarm to the monitoring device 20.

[0059] As described above, this embodiment is designed to suppress false alarms that would occur in conventional security systems if a user 40 leaving the building falls while the exit timer is running and is unable to leave, or if a user 40 entering the building falls while the entry timer is running and is unable to complete the operation to release the security.

[0060] Next, among the various types of arithmetic processing that the CPU 501 of the security device 10 executes in accordance with a program, the function of realizing the monitoring processing, which is a characteristic processing of this embodiment, will be described below.

[0061] Fig. 3 is a block diagram showing an example of functions related to the monitoring process of the security device 10. As shown in Fig. 3, the security device 10 includes a security cancellation unit 31 and an entry timer extension unit 34. The security cancellation unit 31 cancels the start of security if it receives a fall-related information signal from the wearable device 11 carried by the user, indicating that the user has fallen, after receiving a command input from the user to start security and before the predetermined time (exit timer) has elapsed. In security mode, the entry timer extension unit 34 extends the predetermined time (entry timer) after the entry timer has been activated and if it receives a fall-related information signal from the wearable device 11 carried by the user, indicating that the user 40 has fallen, before the predetermined time (entry timer) has elapsed.

[0062] 4-1 and 4-2 are flowcharts showing the flow of the monitoring process of each part in the security system 1, and FIG. 5 is a diagram showing an example of the operation of the monitoring process of each part in the security system 1. In FIG.

[0063] As shown in FIG. 4-1, the operating device 60 receives an operation to switch from the security-off state mode to the security-on state mode (an operation to set security) by the user 40 who is leaving the building (step S1).

[0064] When the security device 10 receives a request to switch to the security mode, it activates an exit timer that delays the switch to the security mode for a predetermined time so that a false alarm does not occur until the user 40 has completely exited the monitored area (step S11).

[0065] Here, as shown in FIG. 5, a case will be described in which wearable device 11 detects a fall of user 40 before a predetermined time expires.

[0066] As shown in FIG. 4-1, when the wearable device 11 detects that the user 40 has fallen, the wearable device 11 transmits a signal indicating that the wearable device 11 has detected the fall of the user 40 to the security device 10 (step S31).

[0067] After the exit timer is started (step S11), if the security cancellation unit 31 of the security device 10 receives a signal from the wearable device 11 indicating that a fall by the user 40 has been detected (step S12: Yes) before the specified time expires (step S13: No), the security cancellation unit 31 stops the exit timer (step S14) and cancels the start of security.

[0068] Thereafter, if the fallen user 40 stands up, the process returns to step S1, and an operation by the user 40 from the operating device 60 to switch from the security-off state mode to the security-on state mode (an operation to set security) is accepted again.

[0069] On the other hand, after starting the exit timer (step S11), if the security device 10 does not receive a signal from the wearable device 11 indicating that a fall by the user 40 has been detected (No in step S12) and the predetermined time has expired (Yes in step S13), it executes a process to switch from the security-off state mode to the security-on state mode (set security) and notifies the monitoring device 20 of this (step S15).

[0070] As described above, according to this embodiment, it is possible to prevent false alarms from being issued when a user who is leaving the facility falls while the exit timer is running and is unable to leave.

[0071] Next, a case where the user 40 enters a facility where security by the security device 10 has started will be described.

[0072] As shown in Figure 4-2, when the security device 10 is in security mode, it waits for a detection signal (No in step S111), and the sensor 50n installed at the entrance / exit detects a user 40 entering the building (step S161).When the security device 10 receives a detection signal from the sensor 50n (Yes in step S111), it activates an entry timer (step S112) that delays the transmission of an intrusion alarm to the monitoring device 20 for a predetermined time until the user 40 completes the switching from security mode to security-disabled mode (security-disabled operation).

[0073] Here, as shown in FIG. 5, a case will be described in which wearable device 11 detects a fall of user 40 who has entered the building before user 40 completes the security release operation.

[0074] When the wearable device 11 detects that the user 40 has fallen, the wearable device 11 transmits a fall-related information signal indicating that the wearable device 11 has detected the fall of the user 40 to the security device 10 (step S131).

[0075] After starting the entrance timer in step S112, the security device 10 waits for the predetermined time to expire (No in step S117), and if a fall-related information signal is received from the wearable device 11 during that time (Yes in step S113), the entrance timer extension unit 34 extends the predetermined time of the entrance timer (step S114).

[0076] Thereafter, if the fallen user 40 stands up within the predetermined time of the extended entry timer, the operating device 60 accepts an operation by the user 40 to switch the security mode to the security release mode (an operation to release security) (step S101), and the operating device 60 transmits a request to switch to the security release mode to the security device 10. The security device 10 waits to receive a request to switch to the security release mode (No in step S115), and if it receives the request (Yes in step S115), it switches the security device 10 to the security release mode and releases security (step S116).

[0077] On the other hand, after starting the entry timer in step S112, if the security device 10 does not receive a fall-related information signal from the wearable device 11 (No in step S113) and the predetermined time has expired (Yes in step S117), it will notify the monitoring device 20 of an intrusion alarm (step S118).

[0078] In this way, according to this embodiment, it is possible to prevent false alarms from being issued in the event that a user entering the facility falls while the entrance timer is running and is unable to complete the operation to release the security.

[0079] In the present embodiment, wearable device 11 detects a fall of user 40 by detecting acceleration information or angular velocity information using, for example, an acceleration sensor or a gyro sensor, but the present invention is not limited to this and may also detect a fall of user 40 by image recognition or sound recognition. Also, any of sensors 50a to 50n may be capable of detecting a fall of user 40. For example, any of sensors 50a to 50n may be an image sensor that detects a person or a person's suspicious behavior by image recognition of an image captured by a camera and detects a fall of a monitored person.

[0080] Furthermore, in this embodiment, the system detects a user falling over while the entrance / exit timer is running, but this is not limiting and the system may respond to other abnormal conditions that can be detected by a sensor, etc. For example, the system may respond to abnormal conditions that can be detected by wearable device 11 or any of sensors 50a to 50n, such as crouching due to temporary dizziness or palpitations.

[0081] (Second embodiment) Next, a second embodiment will be described.

[0082] The second embodiment differs from the first embodiment in that a fall-related information signal is transmitted to the monitoring device 20. In the following description of the second embodiment, the same parts as in the first embodiment will be omitted, and only the differences from the first embodiment will be described.

[0083] Fig. 6 is a diagram showing an example of the overall configuration of a security system 1 according to the second embodiment. As shown in Fig. 6, the wearable device 11 of the security system 1 of this embodiment has a function of connecting to and communicating with an external network such as the Internet, instead of a function of communicating with the security device 10, and transmits a fall-related information signal to the monitoring device 20 via the network N2.

[0084] The network N2 is configured by the Internet, a LAN (Local Area Network), or a combination of these, and may include either a wired network or a wireless network.

[0085] In this case, when the monitoring device 20 receives the fall-related information signal transmitted from the wearable device 11, it transmits a fall-related information reception notification indicating that the fall-related information signal has been received to the security device 10. The security device 10 receives the fall-related information reception notification from the monitoring device 20.

[0086] Therefore, the security cancellation unit 31 of the security device 10 of this embodiment cancels the start of security if it receives a notification of fall-related information from the monitoring device 20 after receiving an instruction to start security from the user 40 and before a predetermined time (exit timer) has elapsed.

[0087] In addition, in the security mode, if the security device 10 of this embodiment receives a detection signal from the sensor 50n installed at the entrance / exit and starts the entry timer, and then receives a notification of receipt of fall-related information from the monitoring device 20 before a predetermined time (entry timer) has elapsed, the entry timer extension unit 34 will extend the predetermined time of the entry timer.

[0088] 7-1 and 7-2 are flowcharts showing the flow of the monitoring process of each part in the security system 1, and FIG. 8 is a diagram showing an example of the operation of the monitoring process of each part in the security system 1. In FIG.

[0089] As shown in FIG. 7-1, the operating device 60 receives an operation to switch from the security-off state mode to the security-on state mode (an operation to set security) by the user 40 who is leaving the building (step S1).

[0090] When the security device 10 receives a request to switch to the security mode, it activates an exit timer that delays the switch to the security mode for a predetermined time so that a false alarm does not occur until the user 40 has completely exited the monitored area (step S11).

[0091] Here, as shown in FIG. 8, a case will be described in which wearable device 11 detects a fall of user 40 before the predetermined time expires.

[0092] As shown in FIG. 7-1, when wearable device 11 detects that user 40 has fallen, it transmits a fall-related information signal indicating that a fall of user 40 has been detected to monitoring device 20 (step S32).

[0093] When the monitoring device 20 receives a fall-related information signal of the user 40 from the wearable device 11, the monitoring device 20 transmits a fall-related information reception notification to the security device 10 indicating that the fall-related information signal has been received.

[0094] After the exit timer is started (step S11), if the security cancellation unit 31 of the security device 10 receives a fall-related information reception notification, which is a signal to stop the exit timer, from the monitoring device 20 before the specified time expires (No in step S13), the security cancellation unit 31 stops the exit timer (step S14) and cancels the start of security.

[0095] Thereafter, if the fallen user 40 stands up, the process returns to step S1, and an operation by the user 40 from the operating device 60 to switch from the security-off state mode to the security-on state mode (an operation to set security) is accepted again.

[0096] On the other hand, after starting the exit timer (step S11), if the security device 10 does not receive a fall-related information reception notification, which is a signal to stop the exit timer, from the monitoring device 20 (No in step S16), and the predetermined time has expired (Yes in step S13), it executes a process to switch from security-off mode to security-on mode (set security) and notifies the monitoring device 20 of this (step S15).

[0097] As described above, according to this embodiment, it is possible to prevent false alarms from being issued when a user who is leaving the facility falls while the exit timer is running and is unable to leave.

[0098] Next, a case where the user 40 enters a facility where security by the security device 10 has started will be described.

[0099] As shown in Figure 7-2, when the security device 10 is in security mode, it waits for a detection signal (No in step S111), and the sensor 50n installed at the entrance / exit detects a user 40 entering the building (step S161).When the security device 10 receives a detection signal from the sensor 50n (Yes in step S111), it activates an entry timer (step S112) that delays the transmission of an intrusion alarm to the monitoring device 20 for a predetermined time until the user 40 completes the switching from security mode to security-disabled mode (security-disabled operation).

[0100] Here, as shown in FIG. 8, a case will be described in which wearable device 11 detects a fall of user 40 who has entered the building before user 40 completes the security release operation.

[0101] When the wearable device 11 detects that the user 40 has fallen, the wearable device 11 transmits a fall-related information signal indicating that the wearable device 11 has detected the fall of the user 40 to the monitoring device 20 (step S132).

[0102] When the monitoring device 20 receives the fall-related information signal from the wearable device 11, the monitoring device 20 transmits a fall-related information reception notification to the security device 10 indicating that the fall-related information signal has been received.

[0103] After starting the entry timer in step S112, the security device 10 waits for the specified time to expire (No in step S117), and during that time, if the entry timer extension unit 34 of the security device 10 receives a fall-related information reception notification, which is a signal to extend the entry timer, from the monitoring device 20 (Yes in step S119), it extends the entry timer (step S114).

[0104] Thereafter, if the fallen user 40 stands up within the predetermined extended time of the entry timer, the operating device 60 accepts an operation by the user 40 to switch the security mode to the security release mode (an operation to release security), and the operating device 60 transmits a request to switch to the security release mode to the security device 10 (step S101). The security device 10 waits to receive a request to switch to the security release mode from the operating device 60 (No in step S115), and if it receives a request to switch to the security release mode from the operating device 60 (Yes in step S115) without receiving a fall-related information reception notification, which is a signal to extend the entry timer, from the monitoring device 20 (No in step S119), within the predetermined extended time of the entry timer (No in step S117), it switches the security device 10 to the security release mode and releases security (step S116).

[0105] On the other hand, after starting the entry timer in step S112, if the security device 10 does not receive a fall-related information reception notification, which is a signal to extend the entry timer, from the monitoring device 20 (No in step S119), does not receive a request to switch to security-off mode from the operating device 60 (No in step S115), and the predetermined time has expired (Yes in step S117), it will notify the monitoring device 20 of an intrusion alarm (step S118).

[0106] In this way, according to this embodiment, it is possible to prevent false alarms from being issued in the event that a user entering the facility falls while the entrance timer is running and is unable to complete the operation to release the security.

[0107] The wearable device 11 may transmit the fall-related information signal to an information terminal such as a smartphone on which a predetermined app is installed via short-range wireless communication such as Bluetooth, and the information terminal may then transmit the fall-related information signal to the monitoring device 20 via the network N2. In this case, the monitoring device 20 may receive the fall-related information signal transmitted from the information terminal and forward it to the security device 10, and the security device 10 may receive the fall-related information signal transmitted from the information terminal via the monitoring device 20.

[0108] (Third embodiment) Next, a third embodiment will be described.

[0109] The third embodiment differs from the first embodiment in that, after a user 40 falls as they leave the building, the security device 10 checks the safety of the fallen user 40 based on whether or not there is a response from the user 40, and resumes the security set process if there is a response from the user 40. In the following explanation of the third embodiment, explanations of the same parts as in the first embodiment will be omitted, and only differences from the first embodiment will be explained.

[0110] 9 is a block diagram showing an example of the functions related to the monitoring process of the security device 10 in the security system 1 according to the third embodiment, and FIG. 10 is a flowchart showing the flow of the monitoring process of each part in the security system 1.

[0111] As shown in FIG. 9, the security device 10 includes a security cancellation unit 31, a timekeeping restart unit 32, and a notification processing unit 33.

[0112] If the timing restart unit 32 receives a further restart instruction signal from the wearable device 11 that received the fall-related information signal before the security cancellation unit 31 cancels the start of security and before the specified time (restart timer) for restarting the exit timer is counted, the timing restart unit 32 restarts the exit timer.

[0113] If the notification processing unit 33 receives a further notification signal from the wearable device 11 that received the fall-related information signal after the security cancellation unit 31 cancels the start of security and before the specified time for restarting the exit timer is counted, the notification processing unit 33 performs notification processing.

[0114] As shown in Figure 10, when wearable device 11 detects a fall by user 40, it transmits a fall-related information signal indicating that a fall by user 40 has been detected to security device 10 (step S31), then activates a notification timer for notifying mobile phone 30 carried by the member in charge of managing and in charge of the monitored area and relevant agencies such as the police and fire department (step S41), displays a reception screen asking whether or not to notify mobile phone 30 carried by the member in charge of managing and in charge of the monitored area and relevant agencies such as the police and fire department (step S42), and receives the request for whether or not to notify mobile phone 30 carried by the member in charge of managing and in charge of the monitored area and relevant agencies such as the police and fire department (step S43).

[0115] 11 is a diagram showing an example of reception of a request for notification. As shown in Fig. 11, the wearable device 11 displays a notification button B1 for notifying the mobile phone 30 carried by the member in charge of managing and overseeing the monitoring area, and the relevant organizations such as the police and fire department.

[0116] Wearable device 11 waits until the time is up to receive the request regarding whether or not a report is required (No in step S43, No in step S44).

[0117] If the wearable device 11 receives a request as to whether or not a report is required (Yes in step S43), and if the report button B1 on the wearable device 11 is pressed to indicate that a report is required (Yes in step S45), the wearable device 11 sends a report instruction to the security device 10 (step S46).

[0118] Similarly, if the wearable device 11 does not receive a request for a report (No in step S43) and the time is up (Yes in step S44), it determines that the fallen user 40 is unable to stand up and move, and sends a report instruction to the security device 10 (step S46).

[0119] On the other hand, if the wearable device 11 receives a request regarding whether or not a report is required (Yes in step S43) and if a report is not required (No in step S45), it sends a resume instruction to the security device 10 to resume the process of switching from the security-off state mode to the security-on state mode (setting security) (step S47).

[0120] Also, as shown in FIG. 10, when the security device 10 receives a fall-related information signal from the wearable device 11 indicating that a fall by the user 40 has been detected (Yes in step S12), it stops the exit timer (step S14), cancels the start of security, and then starts a restart timer to wait for a restart instruction to restart the process of switching from the security-off state mode to the security-on state mode (setting security) (step S21).

[0121] After starting the restart timer (step S21), the security device 10 waits until the timer expires to receive a restart instruction from the wearable device 11 or a reporting instruction from the wearable device 11 (No in step S22, No in step S23, No in step S24).

[0122] When the timekeeping restart unit 32 of the security device 10 receives a restart instruction from the wearable device 11 (Yes in step S22), it stops the restart timer (step S25) and returns to step S11.

[0123] On the other hand, when the reporting processing unit 33 of the security device 10 receives a reporting instruction from the wearable device 11 (Yes in step S23), it executes reporting processing to the mobile phone 30 carried by the personnel in charge of managing and overseeing the monitored area, and to relevant agencies such as the police and fire department (step S26).

[0124] Furthermore, after starting the restart timer (step S21), if the security device 10 does not receive a restart instruction from the wearable device 11 (No in step S22), does not receive a reporting instruction from the wearable device 11 (No in step S23), and the timer expires (Yes in step S24), the security device 10 terminates the processing.

[0125] As described above, according to this embodiment, it is possible to prevent false alarms from being issued when a user who is leaving the facility falls while the exit timer is running and is unable to leave.

[0126] (Fourth embodiment) Next, a fourth embodiment will be described.

[0127] The fourth embodiment differs from the second embodiment in that, after a user 40 falls as they leave the building, the security device 10 checks the safety of the fallen user 40 based on whether or not there is a response from the user 40, and resumes the security set process if there is a response from the user 40. In the following explanation of the fourth embodiment, explanations of the same parts as in the second embodiment will be omitted, and only differences from the second embodiment will be explained.

[0128] FIG. 12 is a flowchart showing the flow of the monitoring process of each unit in the security system 1 according to the fourth embodiment.

[0129] In addition, the timing restart unit 32 of the security device 10 in this embodiment will resume security if it receives a further restart instruction signal from the monitoring device 20 that has received a notification of receipt of fall-related information before the security cancellation unit 31 cancels the start of security and before it has timed the specified time (restart timer) for restarting the exit timer.

[0130] As shown in FIG. 12, if the wearable device 11 does not receive a request for notification (No in step S43) and the time is up (Yes in step S44), it determines that the fallen user 40 is unable to stand up and move, and sends a notification instruction to the monitoring device 20 (step S46).

[0131] On the other hand, if the wearable device 11 receives a request regarding whether or not a report is required (Yes in step S43) and if a report is not required (No in step S45), it sends a restart instruction to the monitoring device 20 to restart the process of switching from the security-off state mode to the security state mode (setting security) (step S47).

[0132] As shown in FIG. 12, monitoring apparatus 20 waits for reception of a restart instruction from wearable device 11 (step S51) and a notification instruction from wearable device 11 (step S52).

[0133] When the monitoring device 20 receives a resume instruction from the wearable device 11 (Yes in step S51), it sends a resume instruction to the security device 10 to resume the process of switching from the security-off state mode to the security-on state mode (setting security) (step S53).

[0134] On the other hand, when the monitoring device 20 receives a notification instruction from the wearable device 11 (Yes in step S52), it executes a notification process to the mobile phone 30 carried by the personnel in charge of managing and in charge of the monitoring area, and to relevant agencies such as the police and fire department (step S54).

[0135] Also, as shown in Figure 12, when the security device 10 receives a notification of receipt of fall-related information from the monitoring device 20 (Yes in step S16), it stops the exit timer (step S14), cancels the start of security, and then starts a restart timer (step S21) that waits for a restart instruction to restart the process of switching from security-off state mode to security-on state mode (setting security).

[0136] After starting the restart timer (step S21), the security device 10 waits for reception of a restart instruction from the monitoring device 20 until the timer expires (No in step S22, No in step S24).

[0137] When the timekeeping restart unit 32 of the security device 10 receives a restart instruction from the monitoring device 20 (Yes in step S22), it stops the restart timer (step S25) and returns to step S11.

[0138] As described above, according to this embodiment, it is possible to prevent false alarms from being issued when a user who is leaving the facility falls while the exit timer is running and is unable to leave. [Explanation of symbols]
