Description

Certification Systems and Programs

[0001] The present disclosure relates to an authentication system and a program.

[0002] Patent Document 1 discloses a construction management system for a building. The construction management system includes a server. The server aggregates information related to the construction work, such as contractual agreements and images of the construction site. Construction management can be carried out smoothly by accessing the information stored in the server from the client's terminal device, the manager's terminal device, and the contractor's terminal device.

[0003] Japanese Patent Application Publication No. 2009-134685

[0004] However, in the construction management system described in Patent Document 1, information about various construction sites is aggregated on a server. For example, if information about construction work that is not related to the client can be accessed from the client's terminal device, a problem in information management will arise. One possible solution to this problem is to set a unique password or the like for each construction site. However, in this case, it becomes necessary to distribute the unique password or the like to all parties involved at the construction site. This hinders smooth information sharing.

[0005] The present disclosure has been made to solve the above-mentioned problems, and an object of the present disclosure is to provide an authentication system and a program that can release security using a simple method.

[0006] The authentication system according to the present disclosure includes a first display unit that displays a first map that includes an authentication location, shows an authentication icon indicating the authentication location, and has a scale larger than a specified boundary threshold; a second display unit that displays a second map that has a scale equal to or smaller than the boundary threshold and does not show the authentication icon when the first map is enlarged or when the authentication icon shown on the first map is selected; and a release unit that releases security when a location on the second map that has been designated and accepted is within an authentication distance from the authentication location.

[0007] The program according to the present disclosure causes a computer to execute a first display step of displaying a first map that includes an authentication location, displays an authentication icon indicating the authentication location, and has a scale larger than a specified boundary threshold; a second display step of displaying a second map that has a scale equal to or smaller than the boundary threshold and does not display the authentication icon when the first map is enlarged or the authentication icon shown on the first map is selected after the first display step; and a deactivation step of deactivating security when the location specified on the second map is within an authentication distance from the authentication location after the second display step.

[0008] According to the present disclosure, security can be released using a simple method.

[0010] The embodiments of the present disclosure will be described with reference to the accompanying drawings. In each drawing, the same or corresponding parts are designated by the same reference numerals. Duplicate descriptions of these parts will be appropriately simplified or omitted.

[0011] Embodiment 1. Fig. 1 is a schematic diagram of a management system in embodiment 1. Fig. 2 is a schematic diagram of an imaging unit of the management system in embodiment 1.

[0012] The management system 1 is applied to a construction site. In particular, as shown in Fig. 1 , the management system 1 is applied to a construction site of an elevator device 200. Hereinafter, as an example, an example in which the management system 1 is applied to a construction site of the elevator device 200, in particular, a modernization site which is a renewal and renovation work for the elevator device 200, will be described.

[0013] Elevator device 200 is provided in building 300. Hoistway 201 of elevator device 200 passes through each floor of building 300. Machine room 202 is provided directly above hoistway 201. Hoistway 201 and machine room 202 are separated by truss 203. Truss 203 forms the ceiling of hoistway 201 and also forms the floor of machine room 202. Although not shown, truss 203 has one or more through holes connecting hoistway 201 and machine room 202. Pit 204 is the lowest part of hoistway 201. A buffer, etc., not shown, is provided in pit 204.

[0014] Rails 205 are provided inside hoistway 201. Rails 205 are provided from truss 203 to pit 204 with their longitudinal direction oriented vertically. Note that management system 1 may be applied to elevator apparatus 200 in a state where rails 205 are not installed or in a state where only a portion of rails 205 is installed in hoistway 201.

[0015] Cage 206 is provided inside hoistway 201. Cage 206 can move up and down inside hoistway 201 while being guided by rails 205. Cage 206 has a cab room 207 inside. The upper side of the ceiling of cab room 207 is the upper surface of car 206, where workers and the like can stand. For example, a car fence 208 is provided on the upper surface of car 206. Note that management system 1 may be applied to elevator apparatus 200 in a state where car 206 is not installed or in a state where only a portion of car 206 is installed in hoistway 201.

[0016] The management system 1 comprises an imaging unit 2, a management server 3, and a viewing terminal 4. The imaging unit 2 is a group of devices installed at a construction site and used to capture an image or a video sequence of images. The management server 3 is composed of devices that enable viewing of the captured image or video of the construction site.

[0017] The viewing terminal 4 is a terminal for viewing images or videos managed by the management server 3. The viewing terminal 4 may be a terminal carried by a worker, a terminal operated by a site agent who supervises the construction site, or a terminal operated by a safety and health instructor who provides guidance on safety and health management at the construction site. The viewing terminal 4 has a screen for displaying information and an input means for accepting input of information. The viewing terminal 4 may be any terminal such as a smartphone, a personal computer, or a tablet.

[0018] Next, the imaging unit 2 will be described with reference to Fig. 2 in addition to Fig. 1. The imaging unit 2 includes a communication device 10, four cameras 20, a network hub 30, a repeater 40, a holder 50, and a power supply 60. The communication device 10, the network hub 30, the repeater 40, the holder 50, and the power supply 60 function as a communication unit for realizing communication between the cameras 20 and a management server 3. The management server 3 stores information for identifying the imaging unit 2. The management server 3 also stores information for identifying each of a plurality of other imaging units 2 (not shown).

[0019] The communication device 10 can communicate with the management server 3 via an external network N1. For example, the communication device 10 can communicate with the management server 3 using wireless communication radio waves. The communication device 10 is also included in a network N2 configured by the imaging unit 2.

[0020] As an example, the communication device 10 has a main body 11 and an installation stand 12. The main body 11 is a portable wireless communication terminal capable of communicating with the network N1. The installation stand 12 is also called a cradle and is a stand that can be electrically connected to the main body 11. The installation stand 12 is an interface that supplies power to the main body 11 and connects the main body 11 to a communication cable.

[0021] The network hub 30 constitutes part of the network N2. The network hub 30 is electrically connected to the installation stand 12 of the communication device 10 via a communication cable 31. The network hub 30 can be considered to be included in the configuration of the communication device 10. In this case, the network hub 30, which is the communication device 10, can be supplied with power via the communication cable.

[0022] The repeater 40 constitutes part of the network N2. The repeater 40 is electrically connected to the network hub 30 via a communication cable 32 that allows signal communication. The repeater 40 receives power from the network hub 30 via the communication cable 32.

[0023] The repeater 40 is placed inside the elevator shaft 201 by a holder 50. The repeater 40 is capable of transmitting and receiving radio waves for communication. Specifically, for example, the repeater 40 is capable of wireless communication using radio waves conforming to the Wi-Fi (registered trademark) standard. The repeater 40 has an antenna surface 41 that transmits directional radio waves. For example, the repeater 40 transmits directional radio waves in the normal direction of the antenna surface 41. The receiving sensitivity of the repeater 40 is designed to be higher on the antenna surface 41 than on other surfaces.

[0024] Generally, wireless radio waves from outside reach the interior of the hoistway 201 with difficulty. For this reason, wireless communication is difficult between the communication device 10 installed in the machine room 202 and the equipment inside the hoistway 201. Furthermore, due to the presence of obstacles such as the car 206 inside the hoistway 201, wireless communication is difficult between the equipment installed at the top and bottom. The repeater 40 relays communication between the communication device 10 and the equipment installed in the hoistway 201 by radio waves. In this case, the repeater 40 maintains a good environment for wireless communication with the equipment installed in the hoistway 201 by transmitting radio waves that are directional in the longitudinal direction of the hoistway 201.

[0025] The power supply 60 is connected to an external power supply (not shown) and supplies power from the external power supply to the communication device 10 and the network hub 30. The power supply 60 has a USB standard terminal that can supply power.

[0026] The four cameras 20 each have the same configuration. The cameras 20 are capable of capturing images or video. The following description will be given of the case where the cameras 20 capture video, but video may be interpreted as images as appropriate. The cameras 20 are capable of recording audio along with video. The cameras 20 perform various functions by appropriately executing stored applications. The cameras 20 constitute part of the network N2. The cameras 20 can communicate with the communication device 10 directly or via the repeater 40. The cameras 20 can communicate with the management server 3 via the network N1 via the communication device 10. The four cameras 20 and the communication device 10 constitute one group. For example, the communication device 10 may be a device that acts as an intermediary with the network N1 and can communicate only with the four cameras 20. The four cameras 20 may be a device that communicates with the network N1 and can communicate only with the communication device 10.

[0027] As an example, the camera 20 has a rechargeable battery and can capture images without receiving an external power supply. For example, the camera 20 is connected to the terminals of the power supply 60 and charged. The camera 20 can be installed in any location using a magnet. Alternatively, the camera 20 may be installed by being mechanically fixed using a mounting fixture.

[0028] The camera 20 has a function of identifying its own location using a GPS (Global Positioning System). After being started up, the camera 20 identifies its own location, generates location information, and transmits the location information to the management server 3.

[0029] Each of the four cameras 20 has unique camera identification information. The four cameras 20 consist of a first camera 20a, a second camera 20b, a third camera 20c, and a fourth camera 20d. The first camera 20a is disposed inside the machine room 202 so as to be able to capture images of the interior of the machine room 202. The second camera 20b is disposed inside the car 206 so as to be able to capture images of the interior of the car 206.

[0030] The third camera 20c is disposed on the upper surface of the car 206 so as to be able to capture an image of at least one of the upper surface of the car 206 and the middle portion of the hoistway 201. For example, the third camera 20c is attached to the car fence 208 of the car 206. The third camera 20c may be attached to the rail 205 or another device in the middle portion of the hoistway 201. The middle portion of the hoistway 201 is the portion between the upper end and the lower end of the hoistway 201. When attached to the upper surface of the car 206, the third camera 20c can be considered to be attached to the middle portion of the hoistway 201.

[0031] The fourth camera 20d is disposed inside the pit 204 at the bottom end of the elevator shaft 201 so as to be able to capture images of the inside of the pit 204.

[0032] Note that a maximum of four cameras 20 included in the imaging unit 2 is sufficient. Because the equipment configuration of the elevator apparatus 200 is concentrated vertically, the number of locations where work can be performed simultaneously during construction of the elevator apparatus 200 is limited. Specifically, from a safety standpoint, although work and the like may be performed in four locations: the machine room 202, the pit 204, the inside of the car 206, and the middle portion of the hoistway 201 above the car 206, it is unlikely that work will be performed in more locations than this simultaneously. For this reason, the imaging unit 2 is designed so that cameras 20 can be installed in a maximum of the four locations described above.

[0033] Next, the camera 20 will be described with reference to Figures 3 and 4. Figure 3 is a front view of the camera of the management system in embodiment 1. Figure 4 is a table showing the status of the camera of the management system in embodiment 1.

[0034] 3, camera 20 has an imaging lens 21 on the front. Camera 20 has a light 22, a power light 23, a first function light 24, and a second function light 25. Camera 20 has a first function button 26 and a second function button 27 on the top surface. Camera 20 is turned on or off by pressing the power button (not shown).

[0035] The light 22 emits light as a flash when taking a picture. The light intensity of the light 22 is relatively strong enough to be noticed by people around the camera 20. The power light 23 is an LED that emits light in a single color. The power light 23 emits light when the camera 20 is turned on. The first function light 24 and the second function light 25 are LEDs that can emit light in any of three or more colors. The first function light 24 and the second function light 25 indicate the current status of the camera 20 by whether or not they emit light and the combination of their colors. Pressing at least one of the first function button 26 and the second function button 27 changes the shooting status and sound recording status of the camera 20. For example, if the first function button 26 is pressed when the camera 20 is waiting to start shooting, the camera 20 starts shooting.

[0036] 4 shows the relationship between the light emission combinations of the first function light 24 and the second function light 25 and the state of the camera 20. Each of the first function light 24 and the second function light 25 is in one of the following states: off O, emitting green G, emitting red R, or emitting yellow Y. The second column of the table shows the state of the first function light 24, and the third column shows the state of the second function light 25. The first column shows the state of the camera 20 corresponding to the combination of the second and third columns.

[0037] For example, when the power of the camera 20 is off, both the first function light 24 and the second function light 25 are off. After the power of the camera 20 is turned on, when an application (camera app) for the camera 20 to transmit video is running, the first function light 24 emits green light and the second function light 25 is off. When the camera 20 is ready to distribute, that is, when it is ready to start capturing video when the first function button 26 is pressed, the first function light 24 emits yellow light and the second function light 25 is off. When the camera 20 is capturing video and simultaneously recording audio, the first function light 24 emits red light and the second function light 25 emits green light.

[0038] Next, the configuration of the management server 3 will be described with reference to Figures 5 and 6. Figure 5 is a diagram showing the equipment configuration of the main parts of the management system in embodiment 1. Figure 6 is a functional block diagram of the main parts of the management system in embodiment 1. Although not shown, the management system 1 includes multiple imaging units 2 installed at multiple construction sites.

[0039] As shown in Figure 5, the management server 3 includes an intermediate server 110 and an information server 120. The intermediate server 110 and the information server 120 are installed in different locations and are separated into different sections on the network. Note that the management server 3 may be configured as an integrated server as long as it includes the functions of the intermediate server 110 and the information server 120. For example, some of the functions described below as functions of the information server 120 may be realized as functions of the intermediate server 110 rather than the information server 120.

[0040] The intermediate server 110 is capable of communicating with the imaging unit 2 and the information server 120 via the network N1. The information server 120 is capable of communicating with the imaging unit 2 via the intermediate server 110 via the network N1. For example, when information is transmitted from the imaging unit 2 to the intermediate server 110, the intermediate server 110 notifies the information server 120 that the information has been transmitted. Note that the information server 120 may be capable of communicating with the imaging unit without going through the intermediate server 110. The intermediate server 110 mainly stores image or video information.

[0041] Information server 120 constitutes part of network N3. Network N3 is managed by the company that owns information server 120 and is an intranet that includes information server 120 and some of the viewing terminals 4. The viewing terminals 4 included in network N3 are included in the internal network of the company that manages information server 120. Viewing terminals 4 that are not included in network N3 but have completed the required security authentication can access network N3 from an external network. Information server 120 mainly manages image or video information stored in intermediate server 110 and provides a management interface for viewing the images or videos on viewing terminals 4. Information server 120 displays the images or videos on the screen of viewing terminal 4 via the management interface. Owners of viewing terminals 4 can view the images or videos.

[0042] 6, the intermediate server 110 includes, as its functions, a first storage unit 111 and a date and time management unit 112. The first storage unit 111 stores information about images or videos transmitted from the camera 20.

[0043] The date and time management unit 112 manages date and time information, which is a combination of a date and a time at a certain point in time. The date and time indicated in the date and time information is used throughout the management system 1. When a startup notification indicating that a camera 20 has started up is received, the date and time management unit 112 transmits the date and time information to the camera 20.

[0044] The information server 120 includes, as its functions, a second storage unit 121, a location management unit 122, a video management unit 123, a screen display unit 124, a first authentication unit 125, and a second authentication unit 126.

[0045] The second storage unit 121 stores various information for managing the devices and security included in the management server 3. Specifically, the second storage unit 121 stores identification information for each of the multiple imaging units 2. For example, the identification information for the multiple imaging units 2 is distinguished by an individual identifier assigned to each communication device 10. The second storage unit 121 stores site information for multiple construction sites managed by the company that owns the management server 3. The site information includes, in association with each other, information on the building that is the construction site, the location of the building that is the construction site, the construction content at the construction site, the construction company involved in the construction site, and the like.

[0046] The position management unit 122 manages the current position information of the imaging unit 2. The position information of the imaging unit 2 is determined by the position information transmitted from the camera 20 of the imaging unit 2. Specifically, consider a case where first position information is first received from an earlier camera 20 of the multiple cameras 20 included in the imaging unit 2, and then second position information is received from a later camera 20 of the multiple cameras 20. When the position management unit 122 receives the first position information from the earlier camera 20, it identifies the imaging unit 2 and determines the position indicated in the first position information as the position information of the imaging unit 2. When the position management unit 122 subsequently receives the second position information, it recognizes that position information for the imaging unit 2 already exists and does not reflect the second position information in the position information of the imaging unit 2. In other words, the position management unit 122 manages the position of the later camera 20 using the first position information rather than the second position information.

[0047] If the second position information received from the subsequent camera 20 is farther away than the specified determination distance from the current position information of the imaging unit 2, the position management unit 122 reflects the second position information in the position information of the imaging unit 2. That is, in this case, the position management unit 122 manages the second position information, rather than the first position information, as the current position information of the imaging unit 2.

[0048] When all the cameras 20 included in a certain imaging unit 2 are powered off, the position management unit 122 may reset the position information of the imaging unit 2 and not manage the position information.

[0049] If the position of the imaging unit 2 is within a determination distance from the position of the construction site indicated in the site information, the video management unit 123 associates the imaging unit 2 with the site information. In other words, it identifies the construction site where the imaging unit 2 is located.

[0050] Furthermore, the video management unit 123 adds information to be managed to the image or video information received from the camera 20 and stores the image or video information in the first storage unit 111. Specifically, when the video management unit 123 receives image or video information from the camera 20, the video management unit 123 associates the identification information of the camera 20, the identification information of the imaging unit 2 including the camera 20, the position information of the imaging unit 2, and the position information of the construction site, and stores the associated information in the first storage unit 111. Here, since the camera 20 captures the image or video information in association with date and time information, the image or video information includes date and time information. Note that if the imaging unit 2 is not associated with the site information because the position of the imaging unit 2 does not correspond to the position of the construction site or because position information has not been received from the camera 20, the video management unit 123 may store the image or video information in the first storage unit 111 without associating it with the position of the construction site.

[0051] The screen display unit 124 provides a management interface for viewing images or videos, and manages the display content of the screen in the management interface.

[0052] An authentication system is configured by first authentication unit 125 and second authentication unit 126. First authentication unit 125 manages access from outside network N3 to the inside of network N3. For example, first authentication unit 125 may manage access to the management interface of a browsing terminal 4 that is not included in network N3. First authentication unit 125 may manage authentication for a browsing terminal 4 that is not included in network N3 to be included in network N3. Note that first authentication unit 125 may manage access to the management interface by a browsing terminal 4 that is included in network N3.

[0053] The second authentication unit 126 manages access for viewing image or video information by a viewing terminal 4 that has been granted access by the first authentication unit 125. That is, the second authentication unit 126 imposes further access authentication on a viewing terminal 4 that can access the network N3. The second authentication unit 126 performs access authentication on the management interface. The functions of the second authentication unit 126 include a first display unit 127, a second display unit 128, and a release unit 129.

[0054] First display unit 127 displays a first map including the authentication location and an authentication icon indicating the authentication location. Second display unit 128 displays a second map including the authentication location but not the authentication icon. Release unit 129 releases security on viewing terminal 4 when the access authentication conditions are met on the second map. In this case, viewing terminal 4 becomes able to access image or video information.

[0055] Next, the process performed by the camera 20 and the management server 3 when the camera 20 is started will be described with reference to Fig. 7. Fig. 7 is a flowchart showing the process performed by part of the management system according to the first embodiment.

[0056] The flowchart of FIG. 7 begins when one of the cameras 20 is activated.

[0057] In step S01, the activated camera 20 transmits a startup notification indicating that it has been activated to the management server 3 via the communication device 10. The following flowcharts will explain the processing of the activated camera 20. At this time, the camera 20 starts, in parallel, a process of identifying its own location using technology such as GPS, a process of activating an image capture application, and the like.

[0058] Then, in step S02, the intermediate server 110 and the information server 120 of the management server 3 receive the startup notification. The date and time management unit 112 of the intermediate server 110 sends the current date and time information to the camera 20.

[0059] Then, in step S03, the camera 20 receives the date and time information and sets the current date and time based on the date and time information.

[0060] Thereafter, in step S04, the camera 20 identifies its current position and determines whether or not it has acquired its own position information.

[0061] If the position information is not acquired in step S04, the operation of step S05 is performed. In step S05, the camera 20 determines whether or not the time during which the position information has not been acquired has exceeded a specified suspension time.

[0062] If it is determined in step S05 that the time during which no position information has been acquired does not exceed the suspension time, the operations from step S04 onwards are repeated.

[0063] If the time during which no position information has been acquired exceeds the suspension time in step S05, the operation of step S06 is performed. In step S06, the camera 20 determines whether or not the preparation of the image capture application is complete. If the preparation of the image capture application is not complete in step S06, the operation of step S06 is repeated.

[0064] If the preparation of the image capture application is complete in step S06, the operation of step S07 is performed. In step S07, the camera 20 is ready to capture images. For example, if the first function button 26 is operated in this state, the camera 20 starts capturing images in association with the date and time information. Then, the operation of the flowchart ends.

[0065] If the location information has been acquired in step S04, the operation of step S08 is performed. In step S08, the camera 20 transmits the acquired location information to the management server 3 via the communication device 10.

[0066] Then, in step S09, the management server 3 receives the position information of the camera 20. The position management unit 122 of the information server 120 determines whether the position information of the camera 20 is the initial position information transmitted from the corresponding imaging unit 2. Whether the position information is the initial position information can be determined by several methods.

[0067] For example, if the position information of the imaging unit 2 is determined within a specified determination time, the position management section 122 may determine that the position information received in step S09 is not the initial position information.

[0068] For example, the location management unit 122 may reset and erase the location information of the imaging unit 2 at a specified time or every time. In this case, when the location information of the imaging unit 2 has not been determined, the location management unit 122 may determine that the location information received in step S09 is the initial location information. When the location information of the imaging unit 2 has been determined, the location management unit 122 may determine that the location information received in step S09 is not the initial location information.

[0069] For example, if the position information of the imaging unit 2 and the position information received in step S09 are farther apart than the judgment distance, the position management unit 122 may determine that the position information received in step S09 is the initial position information.

[0070] If it is determined in step S09 that the received position information is the initial position information, the operation of step S10 is performed. In step S10, the position management unit 122 determines the position of the imaging unit 2 including the camera 20 to be the position indicated in the received position information. That is, the position management unit 122 sets the position information of the imaging unit 2.

[0071] Then, the operation of step S11 is performed. In step S11, the video management unit 123 of the information server 120 associates one of the construction sites with the imaging unit 2 based on the position information of the imaging unit 2 and the site information. At this time, the video management unit 123 may associate the position of the construction site instead of the construction site. Then, the operation from step S06 onwards is performed.

[0072] If it is determined in step S09 that the position information is not the first one, the operation of step S12 is performed. In step S12, the position management unit 122 does not update the position information of the imaging unit 2 that has already been set. In other words, the position management unit 122 manages the position information of the imaging unit 2 based on the position of the camera 20 for which position information was previously received. Then, the operation from step S06 onwards is performed.

[0073] If the location information is not acquired in step S04, the operations from step S06 onward may be performed without making the determination in step S05. In this case, the camera 20 may continue the process of acquiring the location information independently of the image capture application.

[0074] Next, the screens displayed on the management interface will be described with reference to Figs. 8 to 15. Fig. 8 is an authentication screen displayed on the management interface of the management system in embodiment 1. Fig. 9 is a screen of the first map displayed on the management interface of the management system in embodiment 1. Fig. 10 is a screen of the second map displayed on the management interface of the management system in embodiment 1. Fig. 11 is a screen of the second map displayed on the management interface of the management system in embodiment 1. Fig. 12 is a thumbnail screen displayed on the management interface of the management system in embodiment 1. Fig. 13 is a timeline screen displayed on the management interface of the management system in embodiment 1. Fig. 14 is a screen of video display displayed on the management interface of the management system in embodiment 1. Fig. 15 is a screen of video display displayed on the management interface of the management system in embodiment 1.

[0075] 8 shows a login screen on which security authentication is performed by first authentication unit 125. The login screen is displayed on viewing terminal 4 and is a screen to which a user can transition in the management interface. The viewing terminal 4 is a terminal whose access to network N3 has not been released. The login screen includes form F for accepting input of registered password authentication, password authentication for two-step authentication, etc.

[0076] First authentication unit 125 determines whether the authentication conditions for the first authentication are met based on the input information, etc. If the authentication conditions are met, first authentication unit 125 releases the security of viewing terminal 4 so that viewing terminal 4 can access network N3. Note that if viewing terminal 4 is included in network N3, first authentication unit 125 may deem the authentication conditions to be met and release the security of viewing terminal 4.

[0077] 9 to 11 show screens on which security authentication is performed by second authentication unit 126. Fig. 9 shows a screen on which the first map is displayed. First display unit 127 displays the first map on a viewing terminal 4 for which security has been released by first authentication unit 125. Furthermore, first display unit 127 does not display the first map on a viewing terminal 4 for which security has not been released by first authentication unit 125 and which is not able to access network N3.

[0078] The first map is a map with a scale larger than a specified boundary threshold. For example, the first map is a map of Japan that includes most of Honshu, one of the Japanese islands. The first map includes one or more authentication locations. The second authentication unit 126 performs security authentication using location information that can be known only to those who are supposed to view the video of the construction site. The authentication location is a location used by the second authentication unit 126 for security authentication. For example, the authentication location is the location of the construction site. In particular, the authentication location is the location of the modernization site of the elevator device 200.

[0079] The first map shows one or more authentication icons I. The authentication icons I are icons corresponding to authentication locations and indicate the authentication locations. On the first map of the management interface, the authentication icons I can be selected by clicking a mouse, touching a touch panel, or the like.

[0080] A person who wants to view a video of a construction site selects an authentication icon I corresponding to the construction site that the person wants to view on the first map, or enlarges the first map to reduce the scale so that the authentication icon I is included.

[0081] 10 is then displayed on the management interface. Specifically, when a certain authentication icon I is selected on the first map, the second display unit 128 displays on the screen a second map whose scale is equal to a specified boundary threshold and which includes an authentication position corresponding to the selected authentication icon I. Alternatively, when the first map is enlarged to include a certain authentication icon I and the scale becomes equal to or smaller than the specified boundary threshold, the second display unit 128 displays on the screen a second map whose scale is equal to the specified boundary threshold.

[0082] In the example shown in Fig. 10, a second map including Tokyo is shown. The second map is a map whose scale is equal to or smaller than the boundary threshold. That is, the second map includes maps whose scale is smaller than the boundary threshold. The second map includes the authentication location. However, it is not essential that the authentication location be included in the second map. The authentication icon I is not shown on the second map.

[0083] 11 shows the second map, which is enlarged and has a smaller scale than that of FIG. 10. On the second map of the management interface, any position on the map can be specified by clicking a mouse, touching a touch panel, etc. If the position specified on the second map is within a specified authentication distance from the authentication position, the release unit 129 releases the security for viewing images or videos of the construction site corresponding to the authentication position.

[0084] 11 schematically shows a position P whose designation has been accepted, and a circle E of an authentication range whose radius is the authentication distance and whose center is the position P. For example, the authentication distance is 50 m. If the authentication position is located inside the circle E, the distance between the authentication position and the position P whose designation has been accepted is within the authentication distance, so the release unit 129 releases the security. Furthermore, if the position whose designation has been accepted on the second map is farther away from the authentication position than the specified authentication distance, the release unit 129 does not release the security for viewing images or videos of the construction site corresponding to the authentication position.

[0085] In addition, if the location for which the designation is accepted is within the authentication distance corresponding to each of multiple authentication locations, the cancellation unit 129 may display information on the management interface for selecting one of multiple construction sites corresponding to the multiple authentication locations.

[0086] Next, screens for viewing images or videos will be described with reference to Figures 12 to 15. Note that the following description will be given assuming that the videos are stored in the management server 3.

[0087] When the security is released by the release unit 129, the management interface transitions to a screen for selecting a video of the corresponding construction site. The screen display unit 124 displays a screen for selecting a video before the screen for displaying the video.

[0088] 12 shows a first example of a screen for selecting video. In the first example, the screen display unit 124 displays a thumbnail list screen for video. On the thumbnail list screen, videos captured by the cameras 20 of the same imaging unit 2 are displayed in association with each other. On the thumbnail list screen, a date and time are displayed in association with a thumbnail S, which is a portion of the video captured on that date and time. The thumbnail S may also be displayed in association with a portion of the corresponding site information. When a thumbnail S is selected on the thumbnail list screen, the screen display unit 124 transitions the management interface to a screen that displays the video of the selected thumbnail and videos captured by the same imaging unit 2 at the same date and time.

[0089] 13 shows a second example of a screen for selecting video. In the second example, the screen display unit 124 displays a video timeline screen. On the timeline screen, videos captured by the cameras 20 of the same imaging unit 2 are displayed in association with each other. The timeline screen displays a date and time and a bar indicating the date and time when the video was captured. The bar is placed at a corresponding position on the date and time. The multiple bars indicating videos captured by the multiple cameras 20 of the imaging unit 2 are arranged so that the capture times are aligned. When a bar is selected on the timeline screen, the screen display unit 124 transitions the management interface to a screen that displays the video of the selected bar and videos captured by the same imaging unit 2 at the same date and time.

[0090] 14 shows an example of a screen for viewing videos. The screen display unit 124 displays a plurality of captured videos on the management interface screen so that the videos are played back with their dates and times synchronized.

[0091] For example, if, on a certain date and time, first camera 20a, second camera 20b, third camera 20c, and fourth camera 20d included in imaging unit 2 are all capturing images, the four images are associated and stored in first storage unit 111. Since all four images were captured with date and time information reflected, the dates and times shown in the images match each other.

[0092] The screen display unit 124 simultaneously displays the four videos on the same display screen and plays them simultaneously. At this time, the screen display unit 124 synchronizes the dates and times of all the videos when playing them. For example, when an arbitrary playback position is specified with the seek bar B1 of one video, the screen display unit 124 moves the seek bars B1 of the other three videos to the date and time positions corresponding to the specified playback position.

[0093] The screen display unit 124 displays an alert button B2 at a position corresponding to the video. The alert button B2 is a selectable button. When four videos are displayed, four alert buttons B2 corresponding to the four videos are displayed. The four alert buttons B2 correspond to the four cameras 20, respectively.

[0094] When the alert button B2 corresponding to a certain camera 20 is selected by clicking, touching, or the like, the light 22 of that camera 20 flashes. For example, when a site supervisor checking the video from the viewing terminal 4 wants to alert a worker captured on a certain camera 20, he or she selects the alert button B2 corresponding to that camera 20. In this case, the light of that camera 20 flashes, making the worker aware of the alert.

[0095] 15, the screen display unit 124 can also display only one of a plurality of images. An alert button B2 corresponding to the image is also displayed on this screen.

[0096] Next, an example of hardware constituting the information server 120 will be described with reference to Fig. 16. Fig. 16 is a hardware configuration diagram of the information server of the management system according to the first embodiment.

[0097] Each function of the information server 120 may be realized by a processing circuit. For example, the processing circuit may include at least one processor 1000a and at least one memory 1000b. For example, the processing circuit may include at least one dedicated hardware 2000.

[0098] When the processing circuit includes at least one processor 1000a and at least one memory 1000b, the functions of the information server 120 are implemented by software, firmware, or a combination of software and firmware. At least one of the software and firmware is written as a program. At least one of the software and firmware is stored in the at least one memory 1000b. The at least one processor 1000a implements the functions of the information server 120 by reading and executing the program stored in the at least one memory 1000b. The at least one processor 1000a is also referred to as a central processing unit, processing unit, arithmetic unit, microprocessor, microcomputer, or DSP. For example, the at least one memory 1000b may be a non-volatile or volatile semiconductor memory such as RAM, ROM, flash memory, EPROM, or EEPROM, a magnetic disk, a flexible disk, an optical disk, a compact disk, a minidisk, or a DVD.

[0099] When the processing circuit includes at least one dedicated hardware 2000, the processing circuit may be realized, for example, as a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination thereof. For example, each function of the information server 120 may be realized by a processing circuit. For example, each function of the information server 120 may be realized collectively by a processing circuit.

[0100] Some of the functions of the information server 120 may be realized by dedicated hardware 2000, and the remaining functions may be realized by software or firmware. For example, the function of the screen display unit 124 may be realized by a processing circuit as the dedicated hardware 2000, and functions other than the function of the screen display unit 124 may be realized by at least one processor 1000a reading and executing a program stored in at least one memory 1000b.

[0101] Thus, the processing circuitry implements the functions of the information server 120 using hardware 2000, software, firmware, or a combination thereof.

[0102] The information server 120 may be implemented on a cloud server. In this case, the processing circuit is configured by a plurality of partial circuits. The plurality of partial processing circuits are provided in each of the plurality of devices that constitute the cloud server. The plurality of devices that constitute the cloud server may each be provided in a different building.

[0103] Although not shown, the functions of the intermediate server 110 , the viewing terminal 4 , and the camera 20 are also realized by processing circuits equivalent to the processing circuits that realize the functions of the information server 120 .

[0104] According to the first embodiment described above, the authentication system included in the management server 3 includes a first display unit 127, a second display unit 128, and a deactivation unit 129, which are functions realized by a program. When a location specified on the second map is within the authentication distance from the authentication location, security is deactivated. Because no authentication icon is displayed on the second map, a person who can deactivate security is a person who can identify the authentication location on the map. Therefore, the authentication system allows a person who has access to specific information to deactivate security. Furthermore, since security can be deactivated simply by specifying a location on the second map, user convenience can be improved. For example, a safety and health instructor at a construction site is a person who knows the location of the construction site, which is the authentication location, based on other information. The safety and health instructor can deactivate security for accessing video information with simple, intuitive operations.

[0105] The authentication system further includes a first authentication unit 125. A first display unit 127 displays the first map on a viewing terminal 4 that has been enabled to access the inside of network N3 by first authentication unit 125. In this way, two levels of security are set, thereby improving the security of the authentication system.

[0106] In addition, the authentication distance is set to 50 m. Because the condition for deactivating security by the deactivation unit 129 is that a person specifies a location on a map, if the authentication distance is too narrow, it becomes difficult for the person to deactivate the security. On the other hand, if the authentication distance is too wide, security is reduced. By setting the authentication distance to 50 m, a person who knows the authentication location can easily specify the location, and it is possible to prevent a person who does not know the authentication location from erroneously specifying the location.

[0107] Furthermore, the authentication location is the construction site where the elevator is being constructed. Generally, an elevator construction site is indicated on a map as a specific point on a building. In this case, the authentication location directly corresponds to the elevator construction site. Therefore, the authentication location and the location on the map that a person who knows the information about the construction site recognizes as the location of the construction site match. As a result, the authentication location can be easily identified to a person who knows the specific information, such as the location of the elevator construction site.

[0108] Furthermore, when an authentication icon shown on the first map is selected, the second display unit 128 displays a second map whose scale is the boundary threshold value, so that a person who wants to release the security can easily display the second map including the authentication location.

[0109] Furthermore, when the first map is enlarged, the second display unit 128 displays a second map whose scale is equal to the boundary threshold. That is, even if the first map is enlarged so that the scale of the first map exceeds the boundary threshold, the second map whose scale is equal to the boundary threshold is displayed. This makes it less likely that a person will lose track of the authentication position due to excessive enlargement. Furthermore, it is possible to prevent a person from identifying the authentication position on the second map by enlarging the first map using the authentication icon on the first map as a landmark. As a result, security can be improved.

[0110] The management system 1 may also be applied to an elevator system that does not have a machine room and in which the hoisting machine and the like are provided at the bottom or top of the elevator shaft.

[0111] As described above, the authentication system according to the present disclosure can be used for security authentication of an interface for viewing construction footage.
