Description

[Technical Field]

[0001] The present invention relates to a security system, a mobile terminal, a program, and a display method that can process information related to security for a security target such as a business or residence. [Background technology]

[0002] Conventionally, there have been known systems that allow a user to remotely switch security modes using a mobile terminal from a location away from the target of security, such as a home. For example, Patent Document 1 below discloses that a security device can be remotely set / released from a mobile terminal via a homepage provided by a web server, and the security device notifies the web server of the mode switching result, thereby updating the current mode display on the homepage. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-86947 Summary of the Invention [Problem to be solved by the invention]

[0004] However, with the technology of Patent Document 1, although users can grasp the current security mode via the homepage, if there are multiple security areas, such as each floor or room, in a business establishment, the security mode is displayed for each security area, so it is not possible to grasp the security mode for each security area at once.

[0005] In view of the above circumstances, the object of the present invention is to provide a security system, a mobile terminal, a security device, a program, and a display method that enable a user to easily recognize information regarding switching security modes in multiple security areas that constitute the security target. [Means for solving the problem]

[0006] To achieve the above object, one embodiment of the present invention provides a mobile terminal that communicates with a security device that can set a security mode for each of multiple security areas that constitute a security target and that can display a history of changes to the security mode made by users of the security target, and that includes display control means and communication means. When the security device receives a switching request signal from the mobile terminal, it switches the security mode and transmits a mode switching signal indicating the switching result to the mobile terminal. The display control means switchably displays an operation screen that accepts the security mode switching operation from the user, a chat screen that chronologically displays a group of area messages that includes at least a security mode switching message that is switched based on the switching operation for each security area, and a list screen that displays a list of display fields corresponding to the security areas and displays, in each display field, information indicating the current security mode of each security area. The communication means transmits the security mode switching request signal to the security device in response to the user's switching operation on the operation screen. Furthermore, the display control means switches the operation screen to the chat screen in response to the switching operation, and additionally displays, on the chat screen, a mode switching message in response to the mode switching signal received from the security device as the latest message.

[0007] This allows the mobile device to easily allow the user to recognize information regarding the switch on both the list screen and the chat screen when the user switches the security mode for multiple security areas that make up the security target via the operation screen.

[0008] The security mode may include at least an alert mode for monitoring an intrusion abnormality in the security area. In this case, the display control means may switch the chat screen to the list screen when the switching result indicated by the mode switching signal is the alert mode.

[0009] As a result, when a user switches the security mode of a security area to alert mode, the mobile terminal switches the chat screen to a list screen, since it is unlikely that any operations will occur in that security area for a while, and thereby allows the user to see on the list screen whether or not each security area is set to alert mode.

[0010] The security area may include a common area including an entrance / exit of the security target, and individual areas other than the common area. In this case, when the switching result indicated by the mode switching signal is the alert mode and the security modes of all the individual areas have been switched to the alert mode as a result of the switching, the display control means may switch the operation screen to the list screen without via the chat screen, and when the security mode of any individual area is still other than the alert mode as a result of the switching, the display control means may switch the operation screen to the list screen via the chat screen.

[0011] This allows the mobile device to switch the security mode of the shared area to alert mode when the security mode of all individual areas has been switched to alert mode (allowing for the final setting of security targets), and immediately display a list screen to let the user know this, and if there are any individual areas remaining that are not in alert mode, the user can confirm the switching result on the chat screen of the security area being operated, and then understand the security mode status of each individual area on the list screen.

[0012] When the security mode of all the individual areas is switched to the alert mode, the display control means may highlight the display column corresponding to the shared area among the display columns of the list screen switched from the operation screen.

[0013] This allows the mobile device to prompt the user to switch the security mode of the shared area to the alert mode based on the fact that the security mode of all security areas has been switched to the alert mode. Highlighting is, for example, displaying a frame around the display field, changing the text in the display field to bold or other conspicuous text, or coloring the entire display field.

[0014] The mobile terminal may further include location information acquiring means for acquiring location information of the mobile terminal. In this case, when the switching operation is an operation for switching to the alert mode and the security modes of all the individual areas are switched to the alert mode as a result of the switching, and the acquired location information is not near the location information of the security target, the display control means may switch the operation screen or the list screen switched from the operation screen to the chat screen, and additionally display on the chat screen a message urging the user to move into the security target.

[0015] As a result, if the user's switching operation to alert mode is a switching operation that leads to the completion of switching to alert mode for all individual areas, which is a prerequisite for switching to alert mode for the shared area, the mobile device will perform a switching operation to alert mode for the shared area (final setting operation for the guarded object) following the switching operation.However, since performing this final setting remotely from the guarded object should not be permitted for security reasons, if the user is remote, the user can be moved near the guarded object before performing the final setting operation.

[0016] The security mode may include at least an alert mode for monitoring the security area for intrusion abnormalities and an alert release mode for canceling the monitoring. In this case, the display control means may switch the operation screen to the chat screen when the switching result indicated by the mode switching signal is the alert release mode. Furthermore, the display control means may switch the operation screen to the list screen when the switching result indicated by the mode switching signal is the alert mode.

[0017] As a result, when the user switches the security mode of a security area to the disarmed mode, the mobile device can switch to the chat screen for that security area and allow the user to immediately check the chat screen, since there is a possibility that the user will perform some operation to monitor that security area. Also, when the user switches the security mode of a security area to the alerted mode, it is unlikely that any operation will be performed for that security area for some time, so the operation screen can be switched to the list screen, allowing the user to grasp the setting status of the alert mode for each security area on the list screen, including the security area that is the target of operation.

[0018] A security system according to another embodiment of the present invention includes a security device capable of setting a security mode for each of a plurality of security zones constituting a security target, and a portable terminal capable of communicating with the security device and displaying a history of changes to the security mode made by a user of the security target. When the security device receives a switching request signal from the portable terminal, it switches the security mode and transmits a mode switching signal indicating the switching result to the portable terminal. The portable terminal includes display control means and communication means. The display control means switchably displays an operation screen for accepting a security mode switching operation from a user, a chat screen for chronologically displaying a group of zone messages including at least a security mode switching message for switching based on the switching operation for each security zone, and a list screen for displaying a list of display fields corresponding to the security zones, each display field displaying information indicating the current security mode for each security zone. The communication means transmits the security mode switching request signal to the security device in response to the user's switching operation on the operation screen. Furthermore, the display control means switches the operation screen to the chat screen in response to the switching operation, and additionally displays, on the chat screen, a mode switching message in response to the mode switching signal received from the security device as the latest message.

[0019] A program according to another aspect of the present invention is a program that communicates with a security device that can set a security mode for each of a plurality of security zones that constitute a security object, and is executed by a mobile terminal that can display a history of changes to the security mode made by users of the security object. When the security device receives a switching request signal from the mobile terminal, it switches the security mode and transmits a mode switching signal indicating the switching result to the mobile terminal. The program instructs the mobile terminal to: a step of switchably displaying an operation screen that accepts a security mode switching operation from a user, a chat screen that chronologically displays a group of area messages including at least a security mode switching message that is switched based on the switching operation for each security area, and a list screen that displays a list of display fields corresponding to the security areas and displays, in each display field, information indicating the current security mode of each security area corresponding to the display field; transmitting the security mode switching request signal to the security device in response to a switching operation by the user on the operation screen; The control unit executes a step of switching the operation screen to the chat screen in response to the switching operation, and additionally displaying a mode switching message in response to the mode switching signal received from the security device as the latest message on the chat screen.

[0020] A display method according to another aspect of the present invention is a display method using a mobile terminal that communicates with a security device that can set a security mode for each of a plurality of security zones that constitute a security object, and can display a history of changes to the security mode made by users of the security object. When the security device receives a switching request signal from the mobile terminal, it switches the security mode and transmits a mode switching signal indicating the switching result to the mobile terminal. The display method includes the following steps: an operation screen that accepts a security mode switching operation from a user; a chat screen that displays, in chronological order, a group of area messages that includes at least a security mode switching message that is switched based on the switching operation for each security area; and a list screen that displays a list of display fields corresponding to the security areas and displays, in each display field, information indicating the current security mode of each security area corresponding to that display field; transmitting the security mode switching request signal to the security device in response to a switching operation by the user on the operation screen; The method includes switching the operation screen to the chat screen in response to the switching operation, and additionally displaying a mode switching message in response to the mode switching signal received from the security device as the latest message on the chat screen. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0023] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0024] [System Configuration] FIG. 1 is a diagram showing the configuration of a security system according to this embodiment.

[0025] As shown in the figure, the security system includes a security device 100, a user terminal 200, and a center server 300 in a security center.

[0026] The security device 100 is installed in a building (security target T), such as a corporate tenant building, monitors the security target T for abnormalities, and reports any detected abnormalities to a security center. As will be described in detail later, the security device 100 guards the security target T using a number of security modes (e.g., alert mode, alert cancellation mode, presence set mode, etc.).

[0027] The user terminal 200 is, for example, a terminal carried by an employee of a company located in the building of the security target T, and is, for example, a portable computer such as a smartphone, a mobile phone, or a tablet PC (Personal Computer). The user terminal 200 is connectable to a mobile network such as LTE (Long Term Evolution), 3G, or Wi-Fi.

[0028] The user terminal 200 can switch the security mode remotely from the security target T by communicating with the security device 100, and can display the change history of the security mode. The security mode switching operation is input on an application (hereinafter referred to as the "security application") that is installed on the user terminal 200 and provides security mode information and other security information.

[0029] The security device 100 also has an operation unit (such as an operation panel) installed on the wall of each area within the building of the security target T, and when the user is within the building, the user can also use the operation unit to switch the security mode. Depending on the object to be operated by the operation unit, an authentication process may be required, for example, by inserting an authentication card assigned to each user into the operation unit. In this embodiment, the operation unit may also be referred to as the "main unit operation unit" in contrast to the user terminal 200 that can be remotely operated.

[0030] The center server 300 is a server installed in a security center operated by a security company, and is capable of communicating with the security device 100 and the user terminal 200 via the Internet. A controller is stationed at the security center, and when an abnormality report is received from the security device 100, the controller takes necessary measures such as dispatching a security guard to the object being guarded by the security device 100.

[0031] The center server 300 also stores information such as the location of the security object T, and information about users (companies, etc.) who are occupying the security object and have a security contract. For example, the center server 300 pairs the user terminals 200 and security devices 100 of each company occupying the security object T, and stores information that groups these for each security object T for authentication purposes. The center server 300 also stores information about the authentication cards that have been paired and grouped in the same way as the user terminals 200.

[0032] The security mode switching is performed according to the flow shown in (1) to (8) in the figure. That is, (1) the user terminal 200 requests the center server 300 to switch the security mode via the mobile network, (2) the center server 300 authenticates the user terminal 200 (the company to which the user terminal 200 belongs), and if the authentication is successful, transfers the security mode switching request to the security device 100, (3) requesting the security device 100 to switch the security mode. Then, (4) the security device 100 switches the security mode in response to the security mode switching request, and (5) notifies the center server 300 that the security mode switching has been completed.

[0033] Then, (6) the center server 300 receives the notification and requests an API for push notifications on the Internet (for example, Apple Push Notification Service (APNS) or Firebase Cloud Messaging (FCM)) to send a push notification of the completion of the mode switch. (7) Upon receiving the request, the API sends a push notification of the completion of the mode switch to the user terminal 200. (8) The user terminal 200 receives the push notification and displays the completion of the mode switch on its display unit.

[0034] As explained above, in the security mode switching process, the center server 300 only mediates (and authenticates) the communication between the security device 100 and the user terminal 200, and therefore in this embodiment, the communication actually mediated by the center server 300 may be described as communication between the security device 100 and the user terminal 200, with the mediation process intentionally omitted. Note that the security device 100 may be configured to have some of the functions of the center server 300, so that communication between the security device 100 and the user terminal 200 can occur without the center server 300 acting as an intermediary.

[0035] In this embodiment, the user terminal 200 can accept a remote security mode switching operation using the security application, and can display the security mode switching operation and the mode switching result by the security device 100 in response to the mode switching operation as a message on a chat screen. Furthermore, the user terminal 200 can also display information corresponding to the message on a list screen that is a list of display columns for multiple security areas within the security object T. Details of these display processes will be described later.

[0036] [Security device configuration] 2 is a block diagram showing the configuration of the security device 100. As shown in the figure, the security device 100 is made up of a main device 101, various sensors 10 and 12, and the like.

[0037] The intrusion monitoring sensors 10 are sensors for detecting intruders, such as sensors that detect the opening and closing of doors and windows, sensors that detect heat emitted by the human body as a heat source, and sensors that detect when infrared rays are blocked by the human body. These intrusion monitoring sensors are broadly divided into those installed in the outer perimeter area of ​​the security object T and those installed in other areas. Furthermore, the intrusion monitoring sensors installed in the outer perimeter area of ​​the security object T are divided into those installed in entrance and exit areas and those installed in other areas. The fire sensor 12 is a sensor that detects heat and smoke associated with the outbreak of a fire.

[0038] The main unit 101 is composed of a control unit 110, a notification unit 130, a notification unit 140, a display unit 150, an operation unit 160, and a communication interface (I / F) 170.

[0039] If an abnormality occurs, the reporting unit 130 reports it to a security center (not shown) via a communication line. The alarm unit 140 generates various alarm sounds. The display unit 150 is composed of an LED (Light Emitting Diode), a liquid crystal display, etc., and displays various information on and off the main device.

[0040] The communication I / F 170 is an interface for wired or wireless communication with various sensors, etc. The communication I / F 170 also functions as an interface for wireless communication with the user terminal 200, which serves as a remote control unit for switching security modes.

[0041] The operation unit 160 is configured with, for example, operation buttons, a touch panel, etc., and accepts user operations such as switching the security mode, etc. When the operation unit 160 is a touch panel, the operation unit 160 can be integrated with the display unit 150.

[0042] The operation unit 160 also has buttons that can be used for purposes other than switching between security modes, such as an emergency call button that can be operated when the user is attacked by an intruder or feels something is wrong with their body, and a cancel operation button that can be used to cancel an abnormality if the user accidentally causes one.

[0043] The control unit 110 is composed of a processor, memory, etc., and controls the operation of the security device. Functionally, it implements a mode storage means 112, a monitoring and control information storage means 114, an intrusion monitoring sensor detection processing means 116, a mode setting means 118, etc. The mode storage means 112 stores each security mode along with its identification information and stores information about the currently set security mode, for example, as a flag. The monitoring and control information storage means 114 stores the installation area and address codes of various sensors, and stores the correspondence between security modes and various sensors in a monitoring state. When an intrusion monitoring sensor detects an intrusion, the intrusion monitoring sensor detection processing means 116 performs processes such as determining an abnormality and outputting an abnormality signal or determining and outputting an alarm sound based on the current security mode stored in the mode storage means 112 and the contents stored in the monitoring and control information storage means 114. The mode setting means 118 sets (switches) the security mode based on a mode switching operation by the user via the operation unit 160 and the user terminal 200. When the security mode is changed, the mode setting means 118 stores the switched-to security mode in the mode storage means 112 as the current security mode.

[0044] Although not shown, the main device 101 also stores group setting information regarding multiple user terminals 200 and the above-mentioned authentication cards that are paired with the security device 100 and grouped, as well as the identification information of each user (user name, user ID, etc.).

[0045] [User device configuration] 3 is a diagram showing the configuration of the user terminal 200. As shown in the figure, the user terminal 200 includes a CPU (Central Processing Unit) 21, a ROM (Read Only Memory) 22, a RAM (Random Access Memory) 23, an input / output interface 25, and a bus 24 connecting these elements to one another.

[0046] The CPU 21 accesses the RAM 23 etc. as needed, and performs various arithmetic processing while controlling all of the blocks of the user terminal 200. The ROM 22 is a non-volatile memory that permanently stores firmware such as the OS, programs, and various parameters to be executed by the CPU 21. The RAM 23 is used as a working area for the CPU 21, and temporarily stores the OS, various applications currently being executed, and various data currently being processed.

[0047] The input / output interface 25 is connected to a display unit 26, an operation reception unit 27, a storage unit 28, a communication unit 29, and the like.

[0048] The display unit 26 is a display device that uses, for example, an LCD (Liquid Crystal Display), an OLED (Organic ElectroLuminescence Display), a CRT (Cathode Ray Tube), or the like.

[0049] The operation reception unit 27 is, for example, a touch panel, a button, a key, or another input device. When the operation reception unit 27 is a touch panel, the touch panel can be integrated with the display unit 26.

[0050] The storage unit 28 is, for example, a flash memory (SSD; Solid State Drive) or other solid-state memory, or a non-volatile memory such as an HDD (Hard Disk Drive). The storage unit 28 stores the OS, various applications, and various data.

[0051] In particular, in this embodiment, the storage unit 28 stores the security application and other programs that allow the user terminal 200 to execute security mode switching processing in conjunction with the security device 100. The security application also includes data (text information and image information) necessary for displaying an operation screen that accepts security mode switching operations, a chat screen that displays the switching results, and a list screen. The CPU 21 functions as display control means that controls the display switching processing of the operation screen, list screen, and chat screen, and the display processing of messages. The security application also stores the current security mode for each security area set in the security device 100. The security application also stores a message correspondence table that associates security mode switching operations and switching processing with messages to be displayed on the chat screen.

[0052] The communication unit 29 is a module for wireless communication such as LTE or Wi-Fi, and is responsible for communication processing between the security device 100 and the center server 300 via a mobile network and the Internet.

[0053] [Security area] Next, the multiple security areas of the security object T in this embodiment will be described. Fig. 4 is a diagram illustrating the security areas of the security object T. Fig. 4A is a partially see-through view of the exterior of the security object T, and Fig. 4B is a plan view of the floor on which the security object T is located.

[0054] As shown in the figure, the security object T is, for example, a tenant building made up of multiple floors, and has a common area As and multiple individual areas Ai as security objects.

[0055] The common area As is an area that includes, for example, the entrance and exit of the security object T and is shared by employees of the tenant company. The common area As is usually located on the first floor of the security object T, but may also be located on the second floor or higher.

[0056] The individual area Ai is an area used individually by each employee of the tenant company, and may be, for example, an office, a conference room, a laboratory, etc. To enter the individual area Ai, the employee must pass through the common area As.

[0057] The security device 100 can switch the security mode for each individual area Ai individually. To set the security mode for the common area As to alert mode, all individual areas Ai must be set to alert mode. When a user of an individual area Ai sets the security mode for his / her own individual area Ai to alert mode, if all other individual areas Ai are set to alert mode, the user, as the last person to leave the building, performs an operation to set the security mode for the common area As (the entire security target) to alert mode.

[0058] If multiple tenant companies occupy a single security target T, each of the multiple tenant companies will use one or more individual areas Ai and share the common area As. In this case, users of each tenant company cannot switch the security mode for individual areas Ai occupied by other tenant companies, and if the security mode for all of their own individual areas Ai and all individual areas Ai of other tenant companies is set to alert mode, the security mode for the common area As will be set to alert mode.

[0059] In this embodiment, as described below, the user terminal 200 displays a list screen that lists display fields that display information about the security mode for each individual area Ai, and is capable of switching between the list screen, a chat screen that displays messages regarding switching the security mode for each individual area Ai, and an operation screen for switching the security mode.

[0060] [Security mode type] Here, we will explain the types of security modes that the security device 100 has. In this embodiment, the security device 100 has an alert mode, a presence alert mode, and an alert release (presence) mode as security modes for each individual area Ai. The security device 100 also has an alert mode and an alert release mode as security modes for the common area As.

[0061] The monitoring and emergency notification by the fire sensor 12 are performed regardless of the security mode. Any abnormality caused by these is reported by a different alarm sound. On the other hand, the monitoring by the intrusion monitoring sensor 10 differs depending on the security mode.

[0062] The alert mode is a mode that is set when all users in an individual area Ai of the security object T leave (exit) the individual area Ai, and when all users in all individual areas Ai leave (exit) the security object T. In this mode, monitoring by the intrusion monitoring sensors 10 is performed by all the intrusion monitoring sensors 10 installed in the individual area Ai and the common area As.

[0063] The presence alert mode is a mode used when a user is present in an individual area Ai and it is desired to monitor for intrusion from outside. In this mode, monitoring by the intrusion monitoring sensors 10 is performed only by the intrusion monitoring sensors 10 installed in the outer periphery of the individual area Ai, such as windows and doors, out of all the intrusion monitoring sensors 10.

[0064] The disarm mode is used when a user of the individual area Ai is present. In this mode, monitoring is not performed by the intrusion monitoring sensor 10. When a user switches the security mode of an individual area Ai to the disarm mode, if the security modes of all individual areas Ai of the security target T are set to the alarm mode, the common area As is also set to the alarm mode, and the user must first switch the security mode of the common area As to the disarm mode, and then switch the security mode of the individual area Ai to the disarm mode.

[0065] [List screen, chat screen and operation screen] As described above, in this embodiment, the security application of the user terminal 200 switchably displays a list screen that displays a list of information regarding the security mode for each individual area Ai, a chat screen that displays messages regarding the security mode for each individual area Ai in a chronological order in an interactive format, and an operation screen that accepts the user's operation to switch the security mode.

[0066] FIG. 5 is a diagram showing an example of the list screen together with the appearance of the guard target T in FIG. 4A.

[0067] As shown in the figure, the list screen 70 displays a list of display fields 71 ​​corresponding to the shared area As and the individual area Ai. In the example of the figure, the display field 71 corresponding to the shared area As is displayed at the top, and the display field 71 corresponding to the individual area Ai is displayed below it. Note that if the security object T does not have a shared area As, a list of only the individual area Ai is displayed.

[0068] As the display fields 71 ​​corresponding to individual areas Ai, in addition to the display fields 71 ​​corresponding to individual areas Ai for which the user of the individual area Ai has the authority to switch the security mode, display fields 71 ​​corresponding to individual areas Ai for which the user of the individual area Ai does not have the authority to switch the security mode (for example, of other tenant companies) are also displayed, for example at the bottom. However, the display fields for security areas for which the user does not have the authority to operate are not displayed for each security area, but rather, if there are multiple security areas, a single display field 71 is displayed, and in this display field 71, a message is displayed indicating whether all of the security areas for which the user does not have the authority to operate are in alert mode. The user cannot operate this display field 71.

[0069] Each display field 71 displays information such as an area name 72 indicating the name of each security area, a security mode icon 73 that identifies the current security mode status of each security area by color (for example, blue for alert mode and black for disarmed mode), the latest message 74 regarding the security mode that is displayed on the chat screen corresponding to each security area, and the reception time 75 of the latest message 74. Note that even for a display field 71 that displays multiple security areas for which the user does not have the authority to switch the security mode, the latest message 74 regarding the security mode (for example, if all multiple security areas are switched to alert mode, a message saying "Set") and the reception time 75 of the latest message 74 may be displayed.

[0070] As will be described later, the latest security mode messages 74 displayed in each display field 71 include messages indicating the current (switched) security mode for each security area, as well as messages indicating changes to security hours.

[0071] Fig. 6 is a diagram showing an example of the list screen 70 and a chat screen that can be switched from the list screen 70. Fig. 7 is a diagram showing a more detailed example of the chat screen.

[0072] 6, when the user selects any of the display fields 71 ​​on the list screen 70 by tapping or the like, the screen switches to a chat screen for the individual area Ai or the shared area As corresponding to the selected display field 71. The chat screen 80 displays a group of area messages in chronological order, including a switching message corresponding to the switching of the security mode for each security area.

[0073] As shown in Figures 6 and 7, on the chat screen 80, switching messages are displayed in chronological order in an interactive format, separated into different areas (for example, the former on the right and the latter on the left) as switching messages, including a message indicating a mode switching operation by the user (mode operation message 83) and a message indicating the mode switching result by the security device 100 in response to the mode switching operation (mode switching message 84).

[0074] In FIG. 6, the latest message 74 displayed in the display field 71 of the list screen 70 corresponds to the mode switching message 84 displayed at the bottom of the chat screen 80.

[0075] 7, chat screen 80 has a time axis that extends from top to bottom, with older (earlier received) messages being displayed at the top and newer (later received) messages being displayed at the bottom. The most recent message is always added and displayed at the bottom, and older messages that do not fit within the display range of the message display area can be scrolled to the bottom and displayed by the user flicking or swiping the message display area, for example, vertically.

[0076] Each mode operation message 83 and each mode switching message 84 includes, in addition to the message body enclosed in a rectangular frame, operator information, operation tools, and reception time (operation time) information in an adjacent position (e.g., above it).

[0077] In the example of Figure 7, in response to an alert release operation by Taro, the user of user terminal 200, a mode operation message 83 indicating the operation and a mode switching message 84 indicating the result of switching to alert release mode in response to the operation are displayed.

[0078] Furthermore, on the chat screen 80, ordinary messages can be exchanged between multiple users in the security area corresponding to the chat screen 80, and these messages are displayed as messages 86.

[0079] Although not shown in the figure, when a user double-tap on the chat screen 80, a character selection area such as a character input box and keyboard for the user to create a message is displayed, for example, at the bottom, allowing the user to enter a message.

[0080] Furthermore, notification messages from the security device 100 or the security system other than the switching of security modes by the security device 100 may also be displayed on the chat screen 80. Notification messages include, for example, messages 86 (such as a notification that an object has been detected) regarding equipment (temperature, doors, etc.) and sensors (safes, windows, etc.) in the security area corresponding to the chat screen 80 in the disarmed mode, as well as notices regarding crime prevention and disaster prevention information, but are not limited to these.

[0081] Furthermore, when a preset event occurs (for example, when the alert mode is switched to the alert cancellation mode), an image 87 taken by a surveillance camera relating to the event is received from the security device 100 and is additionally displayed on the chat screen 80.

[0082] For example, when a user inputs an operation to cancel the security mode of an individual area Ai, in order to make it possible to confirm whether the user who performed the cancellation operation is the same person as the user who entered the room, video (images or videos) captured by a surveillance camera is transmitted to the user terminal 200 and displayed on the chat screen 80. Furthermore, when a sensor on a safe or window detects something, an image from the surveillance camera around the safe or window may be transmitted to the user terminal 200 and displayed on the chat screen 80, or a message indicating the detection may be additionally displayed.

[0083] Also, for example, at the bottom of the chat screen 80, an operation menu button 81 and a setting menu button 82 are displayed.

[0084] The operation menu button 81 is a button for switching between the operation screen and the chat screen 80. The setting menu button 82 is a button used when changing various settings related to user information and the like.

[0085] Also, for example, in the upper left corner of the chat screen 80, a security mode display icon 85 is displayed which indicates the current security mode of the security area corresponding to the chat screen 80. For example, the security mode display icon 85 is displayed in blue if the security area is in alert mode, and in black if not. Furthermore, on the chat screen 80, the security mode display icon 85 also functions as a list screen return button for switching the chat screen 80 to the list screen 70 when tapped by the user.

[0086] FIG. 8 is a diagram showing an example of the operation screen.

[0087] As shown in the figure, when the user taps an operation menu button 81 on the chat screen 80, the operation screen 90 is displayed so as to overlap the chat screen 80, for example.

[0088] The operation screen 90 is configured as a user interface using, for example, a touch panel, and in addition to the operation menu button 81 and setting menu button 82 that are provided in common with the chat screen 80, has an in-zone area selection button 91, a status check button 92, an alert mode setting button 93, an alert cancellation mode setting button 94, a presence alert mode setting button 95, and a security time change button 96. Each button is displayed on the screen as a button icon, and when the user taps on the corresponding button icon area, it is recognized as a selection operation of that button.

[0089] The in-zone area selection button 91 is a button for selecting an area as a target for a security mode switching operation when an individual zone Ai is further divided into a plurality of areas and guarded.

[0090] The status confirmation button 92 is a button for confirming the current security mode status of the individual area Ai.

[0091] The alert mode setting button 93 is a button that accepts a tap operation for switching from alert release mode to alert mode, and the alert release button 94 is a button that accepts a tap operation for switching from alert mode to alert release mode.

[0092] The presence alarm mode setting button 95 is a button that accepts a tap operation for switching the current security mode to the presence alarm mode.

[0093] The security time change button 96 is a button that accepts an operation to change (extend, etc.) the set time in relation to a function that automatically switches the individual area Ai to security mode or makes a phone call to the user from the security center if the security mode for the individual area Ai has not been set even at the time that the user has previously set. When the security time change button 96 is tapped, a screen for inputting the changed set time is displayed, and the user can change the time on that screen.

[0094] 9 is a diagram showing an example of how the chat screen 80 is displayed when a security guard time change operation is input using the security guard time change button 96. As shown in the figure, in response to the tap operation, a security guard time operation message 88 indicating the operation and a security guard time change message 89 indicating the changed security guard time are displayed.

[0095] As described above, the latest messages 74 regarding security modes displayed in each display column 71 on the list screen 70 include not only messages indicating the current (switched) security mode for each security area, but also messages indicating changes to the security time.

[0096] In other words, if the latest message added to and displayed on the chat screen 80 is a mode switching message 84 or a security time change message 89, the latest message 74 corresponding to that message will be displayed in the display field 71 corresponding to the chat screen 80 on the list screen 70.

[0097] On the other hand, if the latest message added and displayed on the chat screen 80 is not a mode switching message 84 or a security time change message 89 but a regular message 86 from a user or the system, the message 86 will not be displayed in the display field 71 of the list screen 70, and the display of the latest message among the messages corresponding to the mode switching message 84 or security time change message 89 on the chat screen 80 will be maintained as the latest message 74.

[0098] When the user operates any of the above buttons, the user terminal 200 transmits to the security device 100 a signal requesting switching to the corresponding security mode.

[0099] The operation screen 90 can be switched to the chat screen 80 by operating the operation menu button 81, and can also be switched to the chat screen 80 by operating the close button provided in the upper right corner, for example.

[0100] When the security application is started or when switching to the operation screen 90, a pop-up prompting the user to enter a passcode for user authentication is displayed, and operation of each mode setting button is enabled when the user correctly enters the passcode. Biometric authentication such as a fingerprint can be used as a user authentication method instead of a passcode. User authentication may also be performed when each mode setting button is pressed on the operation screen 90.

[0101] Furthermore, if the security target T is made up of multiple buildings, the above-mentioned list screen 70 is prepared for each building, and above the list screen 70 for each building, a list screen 70 for selecting a building is provided, as shown in Figure 10.

[0102] The top list screen 70 has a display field 76 for each building, and the display field 76 has a building name 77 that indicates the name of the building, a security mode display icon 79 that indicates the current security mode for the entire building, and a radio button 78 for selecting the list screen 70 corresponding to the building. The security mode display icon 85 is displayed in blue if all security areas of the building are in alert mode, for example, and in black if not.

[0103] Furthermore, if multiple buildings as security targets T are divided into areas, a list screen for selecting an area may be provided above the list screen 70 corresponding to the buildings.

[0104] [Security system in operation] Next, the operation of the security system configured as described above will be explained. This operation is performed by the cooperation of hardware such as the CPU and communication unit of the security device 100 and the user terminal 200, and software stored in the storage unit. For convenience, in the following explanation, the control unit 110 of the security device 100 and the security application or CPU 21 of the user terminal 200 are considered to be the main operating entities.

[0105] Fig. 11 is a flowchart showing the flow of the screen switching process in the security system, and Fig. 12 is a diagram showing an example of the transition of the screen on the user terminal 200 when the security mode is switched.

[0106] 11, first, the CPU 21 of the user terminal 200 starts the security application based on a user operation (step 111). When the security application starts, it displays the list screen 70 as a main screen (step 112).

[0107] Next, the security application determines whether or not the user has pressed any of the display fields 71 ​​on the list screen 70 (step 113).

[0108] If it is determined that any of the display fields 71 ​​has been pressed (Yes), the security application switches the list screen 70 to the chat screen 80 corresponding to the pressed display field 71 (step 114).

[0109] Next, the security application determines whether the user has pressed the operation menu button 81 on the chat screen 80 (step 115).

[0110] If it is determined that the operation menu button 81 has been pressed (Yes), the security application displays the operation screen 90 superimposed on the chat screen 80 (step 116).

[0111] Next, the security application determines whether or not an operation to switch the security mode has been input on the operation screen 90 (step 117).

[0112] If it is determined that a security mode switching operation has been input on the operation screen 90 (Yes), the security application transmits a switching request signal corresponding to the switching operation (step 118). The switching request signal includes user identification information of the user who is the operator of the user terminal 200, mode identification information indicating the security mode after switching, and information identifying the individual area Ai to which the security mode is to be switched.

[0113] In addition, upon input of the switching operation, the security application switches the operation screen 90 to the chat screen 80 and additionally displays a mode operation message 83 corresponding to the input mode switching operation (see the leftmost and second from the left diagrams in Figure 12).

[0114] Upon receiving the switching request signal, the security device 100 switches the security mode based on the mode identification information included in the switching request signal (step 119). At this time, when switching to the alert mode, the security device 100 checks the detection status of each intrusion monitoring sensor 10, and switches to the alert mode only if none of the sensors are detecting anything and are in a normal state.

[0115] Next, the security device 100 determines whether or not this security mode switch has set all individual areas Ai to security mode and it has become necessary to set the common area As to security mode (final setting) (step 120).

[0116] If it is determined that a final set is necessary (Yes), the security device 100 generates a mode switching signal including information about the final set (step 121). In addition to the information about the final set, the mode switching signal includes mode identification information that identifies the security mode after switching, user identification information that identifies the operator who switched the security mode and is included in the switching request signal, and information that identifies the individual area Ai that is the target of the security mode switching.

[0117] If it is determined that the final set is not necessary (No), the security device 100 generates a mode switching signal that does not include information regarding the final set (step 122).

[0118] The security device 100 then transmits the generated mode switching signal to the user terminal 200 (step 123).

[0119] The security application of the user terminal 200 that has received the mode switching signal determines whether the final setting is necessary based on the mode switching signal (step 124).

[0120] If it is determined that a final setting is necessary (Yes), the security application identifies the individual area Ai to which the security mode has been switched, the security mode after the switch, and the operator from the mode switching signal (step 125).

[0121] Next, the security application switches the chat screen 80 to the list screen 70 (step 126) and updates the display of the security mode icon 73 and the latest message 74 in the display field 71 corresponding to the individual area Ai to which the security mode has been switched (step 127) (see the diagram on the right side of Figure 12).

[0122] Furthermore, the security application highlights the display field 71 corresponding to the shared area As on the list screen 70 (step 128). Highlighting includes, but is not limited to, surrounding the display field 71 with a color frame, changing the background color of the display field 71, coloring the area name, making the text larger or bolder, etc. In the example of FIG. 12 (the diagram on the right), the display field 71 for the shared area As is surrounded by a color frame.

[0123] This allows the security application to prompt the user to switch (finally set) the security mode of the shared area As to alert mode based on the fact that the security mode of all security areas has been switched to alert mode.

[0124] On the other hand, if it is determined in step 124 that a final setting is not necessary (No), the security application identifies the individual area Ai to which the security mode has been switched, the security mode after the switch, and the operator from the mode switching signal (step 129).

[0125] The security application then generates a mode switch message 84 from the identified information (step 130).

[0126] The security application then displays the generated mode switching message 84 on the chat screen 80 (step 131) (see the second diagram from the right in FIG. 12).

[0127] [summary] As described above, according to this embodiment, when a user switches the security mode in multiple security areas of the security object T via the operation screen 90, the user terminal 200 allows the user to easily recognize information regarding the switch on both the chat screen 80 and the list screen 70 (the chat screen 80 provides detailed information about each security area, and the list screen 70 provides an overview of the security mode for the entire security object T).

[0128] [Variations] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and scope of the present invention.

[0129] In the above-described embodiment, the chat screen 80 is switched to the list screen 70 only when the final setting is required, but this is not limited to this. For example, if the switching result of the mode switching signal is the alert release mode, the chat screen 80 may continue to be displayed, and if the switching result of the mode switching signal is the alert mode (a setting switching result of the alert mode for the individual area Ai that is not the final one), the chat screen 80 may be switched to the list screen 70.

[0130] Furthermore, in the above-described embodiment, when a mode switching operation is input on the operation screen 90, the security application switches the screen from the operation screen 90 to the chat screen 80. However, the security application may continue to display the operation screen 90 until a mode switching signal is received from the security device 100, and may change the screen to be switched from the operation screen 90 depending on the switching result indicated by the received mode switching signal. For example, when the switching result is the alert release mode (when the user's switching operation is the alert release operation), the operation screen 90 may be switched to the chat screen 80, whereas when the switching result is the alert mode (when the user's switching operation is the alert set operation), the operation screen 90 may be switched to the list screen 70 without switching to the chat screen 80.

[0131] As a result, when the user performs an alarm cancellation operation, the security application can switch to the chat screen 80 for that individual area Ai, allowing the user to immediately check that chat screen 80, since there is a possibility that some operation will be performed to monitor the individual area Ai.On the other hand, when the user performs an alarm set operation, since it is unlikely that any operation will be performed for that individual area Ai for some time, the security application can switch the operation screen 90 to the list screen 70, allowing the user to grasp the setting status of each individual area Ai, including the individual area Ai that is the target of the operation, on the list screen 70.

[0132] Furthermore, in the above-described embodiment, the security application switches the screen when it receives the switching result of the received mode switching signal, but the screen may also be switched when the user performs a mode switching operation. For example, if the user's security mode switching operation is a switching operation that requires a final setting (all individual areas Ai are set to alert mode), as shown in the leftmost and second from the left diagrams in FIG. 13, the operation screen 90 may be switched to the list screen 70 without going through the chat screen 80.

[0133] The subsequent operation is the same as in the case of Figure 12 above, in which the security mode icon 73 and latest message 74 in the display field 71 corresponding to the individual area Ai where the security mode has been switched are updated, and the display field 71 is highlighted (see the second figure from the right in Figure 13).

[0134] On the other hand, if the final setting is not required even after the switching operation (the security mode of any individual area Ai is other than the alert mode), the security application may switch the operation screen 90 to the list screen 70 via the chat screen 80 (after displaying the mode operation message 83 and the mode switching message 84 on the chat screen 80).

[0135] As a result, when the security mode of all individual areas Ai has been switched to alert mode, the security application can switch the security mode of the shared area As to alert mode (allowing for the final setting of security targets), and can immediately display the list screen 70 to let the user know this, and if there are any individual areas Ai remaining that are not in alert mode, the user can confirm the switching result on the chat screen 80 of the individual area Ai being operated, and then understand the security mode status of each individual area Ai on the list screen 70.

[0136] Furthermore, the security application may be configured so that when a mode switching operation that requires final setting is input, the switching operation cannot be performed remotely. That is, the security application may acquire location information (e.g., GPS (Global Positioning System) information, base station information, etc.) of the user terminal 200, and allow the user to perform the mode switching operation only when the location information indicates that the user is located inside the building of the security target T (or in the vicinity within a predetermined range). Alternatively, in this case, the security application may be controlled so that the final setting can only be performed from the main body operation unit of the security device 100.

[0137] Specifically, as shown in the second figure from the right in Figure 13, when the location information of the user terminal 200 is near the location information of the security target T, the security application updates the display of the security mode icon 73 and latest message 74 in the display field 71 corresponding to the individual area Ai where the security mode has been switched, and highlights the display field 71, as in the case of Figure 12 above.

[0138] On the other hand, as shown in the rightmost diagram of FIG. 13 , when the location information of the user terminal 200 is not near the location information of the security target T, the security application may switch the list screen 70, which has been switched from the operation screen 90, to a chat screen 80, and additionally display a message on the chat screen 80 urging the user to move into the security target T (e.g., "Please move inside the building before performing the set operation"). Alternatively, in this case, when the location information is not near the location information of the security target T, the security application may directly switch from the operation screen 90 to the chat screen 80. Note that the same control may also be performed for screen switching in accordance with the switching result of the received mode switching signal in the above-described embodiment. That is, when the operation screen is switched to the chat screen by the user's mode switching operation, and the received mode switching signal indicates that final setting is required and the location information of the user terminal 200 is near the location information of the security target T, the screen may be switched from the chat screen to the list screen, and when final setting is required and the location information of the user terminal 200 is not near the location information of the security target T, a message urging the user to move into the security target T may be additionally displayed.

[0139] As a result, if the user's switching operation to alert mode is a switching operation that leads to the completion of switching all individual areas Ai to alert mode, which is a prerequisite for switching the shared area As to alert mode, the security application will perform a switching operation to alert mode for the shared area As (final set operation for the guarded object T) following the switching operation.However, since performing this final set remotely from the guarded object T should not be permitted for security reasons, if the user is remote, the user can be moved near the guarded object T and then the final set operation can be performed.

[0140] Furthermore, in the above-described embodiment, the security application may switch the chat screen 80 after the above switching operation to the list screen 70 (for example, after displaying the mode switching message 84) not only when the user's mode switching operation is the final setting operation, but also when the user operates to set the alert mode for a non-final individual area Ai. In this case, the chat screen 80 is switched to the list screen 70 by the user's operation to set the alert mode, and the chat screen 80 continues to be displayed by the user's operation to cancel the alert mode.

[0141] As a result, when the user switches the security mode of an individual area Ai to alert mode, since it is unlikely that any operations will occur in that individual area Ai for a while, the security application switches the chat screen 80 to the list screen 70 (after making the user aware of the mode switch with the mode switch message 84), thereby allowing the user to get an overview of the setting status of each individual area Ai on the list screen 70.

[0142] In the above embodiment, when the final set operation is input, the security application highlights the display field 71 corresponding to the shared area As on the list screen 70, but it is not necessary to highlight the display field 71. Furthermore, if there are many display fields 71 ​​on the list screen 70 and the user cannot see the display field 71 corresponding to the shared area As without scrolling, the security application may control the screen when transitioning to the list screen 70 so that the display field 71 corresponding to the shared area As is displayed in a prominent position, such as at the top of the screen.

[0143] In the above embodiment, the security application determined whether or not a final set was required by checking whether or not information regarding the final set was included in the switching request signal received from the security device 100, as shown in Fig. 11. However, the security application may determine whether or not a final set is required by checking the history of mode switching signals received from the security device 100 up to that point when it receives a mode switching operation from the user, without waiting for a switching request signal from the security device 100, and by checking whether or not setting an individual area Ai to the alert mode through the mode switching operation will result in all individual areas Ai being set to the alert mode.

[0144] In the above-described embodiment, the display position of each display column 71 on the list screen 70 may be dynamically changed. For example, the display column 71 corresponding to the individual area Ai where the security mode has been switched and a new message has been received may be positioned at the top. However, even in this case, the display column 71 corresponding to the shared area As may be fixed at the top, for example.

[0145] Furthermore, each display field 71 on the list screen 70 may be displayed in the form of a floor map so that the arrangement of each display field 71 corresponds to the position of the individual area Ai on each floor of the security object T consisting of multiple floors.

[0146] In the above-described embodiment, the latest message 74 displayed in each display field 71 on the list screen 70 is a message related to switching of the security mode and changing of the security time, but is not limited thereto, and the latest message on the chat screen 80 may be displayed as the latest message 74. Furthermore, the latest message 74 may be displayed in an abbreviated form.

[0147] In the above-described embodiment, each display column 71 of the list screen 70 displayed the reception time 75 of the latest message 74, but instead of the reception time, the time when the security area corresponding to the display column 71 switched to the current security mode (the reception time of the latest mode switching message 84 on the chat screen 80) may be displayed.

[0148] In the above-described embodiment, when there are multiple display fields 71 ​​on the list screen 70 corresponding to individual areas Ai for which the user does not have the authority to perform mode switching operations, they are displayed together, but they may also be displayed for each individual area Ai.

[0149] In the above-described embodiment, the content of the mode switching message 84 displayed on the chat screen 80 may be set to differ depending on whether the user of the user terminal 200 is the operator who performed the security mode switching operation or not. For example, if the user is the operator, the mode switching message 84 may be displayed with content such as "Go home in peace," informing the user that the security device 100 (security system) has recognized the user's mode switching operation, whereas if the user is not the operator, the mode switching message 84 may be displayed with content such as "Set," informing the user directly of the fact that the security mode has been switched.

[0150] In the above-described embodiment, on the list screen 70 and the chat screen 80, the security mode display icon (list screen return button) 85 indicated the current security mode by the color of the icon, but the current security mode may also be indicated by characters such as "alert" or "cancel" or by changing the icon design. For example, if an individual area Ai is further divided into multiple areas and guarded, an icon that can distinguish the security mode for each area may be displayed for each security area, and the icon design may be changed depending on the area or security area whose security mode has been switched.

[0151] In the above-described embodiment, if the individual area Ai is further divided into multiple areas, the mode switching message 84 displayed on the chat screen 80 may not be a message regarding the entire individual area Ai, such as "It's set," but may be a message that clearly indicates the area within the individual area Ai for which the security mode has been switched.

[0152] In the above-described embodiment, the operation screen 90 is displayed superimposed on the chat screen 80, but the operation screen 90 may be displayed independently of the chat screen 80. Furthermore, the operation screen 90 may be switchable not only from the chat screen 80 but also from the list screen 70. In this case, when the security mode icon 73 in each display field 71 of the list screen 70 is selected by tapping, the operation screen 90 related to the security area corresponding to that display field 71 may be displayed.

[0153] In the above-described embodiment, when switching to alert mode, if the security device is not in a normal state, it may send a signal to the user terminal containing a notification that the mode cannot be switched, and the security application may display a message to that effect on the chat screen.

[0154] Among the inventions described in the claims of this application, the invention described as a "display method" has each step automatically performed by at least one device such as a computer through information processing by software, and is not performed by a human using a device such as a computer. In other words, the "security method" is an information processing method using computer software, and is not a method in which a human operates a calculation tool called a computer.
