The control system 200 transmits information to the entrance / exit management system 400 via the linking processing unit 220 requesting permission for an operator to pass through a building entrance / exit and / or door if a malfunction of the elevator 121 is detected and it becomes necessary to dispatch the operator to the building. This allows the operator to pass through the doors such as the entrance and quickly reach the elevator 121.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] The present invention relates to an elevator management system and an elevator management method. [Background technology]

[0002] Conventionally, when an elevator installed in a building breaks down, workers from a maintenance company contracted by the building go to the site and carry out repairs to fix the breakdown. For example, if an elevator breaks down and a report of the breakdown is sent to the control center monitoring that elevator, the control center dispatches a worker in charge of elevators in the relevant area to the local building and has the worker carry out work to restore the elevator.

[0003] Incidentally, in recent years, an increasing number of office buildings and apartment complexes equipped with elevators have begun to lock the entrances to the building and require users or residents of the building to go through an authentication process using a security card or other means before the entrances can be unlocked and people can enter the premises.

[0004] In the case of buildings that require security procedures when entering, if an elevator in the building breaks down, workers dispatched from the elevator maintenance company must contact the building manager or other person to unlock the entrance. However, depending on the building, the manager is often not present, and there are cases where it takes time for the workers to enter the building.

[0005] Patent Document 1 describes a technology in which, when a maintenance request is sent to a monitoring and maintenance center due to a breakdown in facility equipment such as a production device in a factory, access right information and a logical key required to carry out the work on-site are generated and sent to the mobile terminal of a worker. This enables a worker who has gone to the site to log in to the control terminal of the facility equipment where the breakdown has occurred using the access right information. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2004-38440 A Summary of the Invention [Problem to be solved by the invention]

[0007] Security management for the building's entrances and each room is carried out by a dedicated security system, which is operated by a completely separate system from the control system for the building's equipment, such as elevators. The access right information described in Patent Document 1 is access right information to a control device of facility equipment such as elevators. Since the control center that manages facility equipment such as elevators does not have information for unlocking the entrances to the building, it is impossible for the control center to send information for unlocking the entrances to the workers who are working to restore the elevators.

[0008] As a result, workers performing work on elevators had to contact the building manager or other relevant person and complete the necessary procedures to enter the building, which made entering the building a time-consuming and cumbersome process. For example, in the case of an elevator breakdown, since people's movement within the building is restricted during the breakdown, workers are expected to start the restoration work of the affected elevator as soon as possible. Therefore, taking time and effort to enter the building is undesirable as it will delay the completion of restoration. In particular, if someone is trapped in the elevator due to the breakdown, workers are in a situation where they cannot take the time and effort to enter the building, since a quick rescue operation is required.

[0009] In view of the above, an object of the present invention is to provide an elevator management system and an elevator management method that allow elevator workers to quickly enter a building on-site. [Means for solving the problem]

[0010] In order to solve the above problems, for example, the configurations described in the claims are adopted. The present application includes multiple means for solving the above problems, and one example is an elevator management system that is applied to manage elevators installed in a building where building entrances and / or door passage is controlled by an access control system, and the elevator management system comprises an elevator control unit that controls the elevators, and a control system that is connected to the elevator control unit via a network and remotely monitors the elevators, and the control system has a coordination processing unit that exchanges information with the building's access control system. Here, when the control system detects an elevator malfunction and it becomes necessary to dispatch workers to the building, it sends information to the access control system via the coordination processing unit requesting permission for the workers to pass through the building entrance / exit and / or door. Effect of the Invention

[0011] According to the present invention, authentication information that allows passage through a building can be transmitted to a worker's terminal, etc., based on a request from the control system. Therefore, the travel time from the worker's arrival on-site to the corresponding location can be shortened, which leads to ensuring the quality and time of work that requires urgency, and it is possible to provide high-quality maintenance services. Problems, configurations and effects other than those described above will become apparent from the following description of the embodiments. [Brief description of the drawings]

[Figure 4] FIG. 2 is a diagram showing an example of a display screen on a terminal of the building monitoring system according to the embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] An elevator management system and an elevator management method according to one embodiment of the present invention (hereinafter referred to as "this example") will be described below with reference to the accompanying drawings.

[0014] [Overall configuration of elevator management system] FIG. 1 shows the overall configuration of an elevator management system according to this embodiment. In the elevator management system of this example, an elevator (elevator) 121 is installed in a building 100, and an elevator control unit 120 controls the ascent and descent of the elevator 121. That is, the elevator control unit 120 monitors the operation status of the elevator 121. Also, cameras 122 are installed at the landing and inside the car of the elevator 121. The elevator control unit 120 is capable of communicating with a control system (control center) 200 via a communication device 110 connected to a closed network 500, and when an abnormality occurs in the elevator 121, the elevator control unit 120 notifies the control system 200 of the abnormality. The closed network 500 is a dedicated line or a telephone line that connects the location where the control system 200 is installed with the building 100.

[0015] In addition, an electric lock 141 is installed at an entrance door 142 in the building 100, and an entrance / exit control unit 140 controls the locking and unlocking of the electric lock 141. Here, the entrance door 142 includes a plurality of doors, such as the door at the entrance of the building 100, a door installed in the middle of a corridor, and a door installed in each room. The entrance / exit control unit 140 performs authentication processing based on information read by a card reader (not shown) installed near the door 142 at the entrance / exit of the building 100. Then, the entrance / exit control unit 140 performs processing to unlock the electric lock 141 when it reads the information of a person with passage permission. In addition, in the elevator management system of this example, the areas of the building 100 through which each permitted person can pass are individually set, and based on the information on the areas through which each person can pass, it is individually set whether or not to perform the process of unlocking the electric locks 141 of each door 142 inside the building 100.

[0016] Note that performing authentication processing using a card reader is just one example, and the entrance / exit control unit 140 can apply various authentication processing methods, such as inputting a number for unlocking or face recognition. A camera 143 is installed near the entrance door 142, and the entrance / exit control unit 140 records an image of the vicinity of the door 142 taken by the camera 143.

[0017] The entrance / exit control unit 140 that controls the electric lock 141 is capable of communicating with the building monitoring system 300 and the entrance / exit control system 400 via a communication device 130 that is connected to a wide area network 502 . A management terminal 150 is also installed in the manager's room of the building 100. The display unit 151 of the management terminal 150 is configured to display the status of the building 100, such as the occupancy status of each room, the air conditioning status, and the security status. These displays are based on information received from the building monitoring system 300 and the entrance / exit management system 400 via the wide area network 502.

[0018] The control system 200 monitors the elevators 121 installed in the building 100, and when an abnormality is reported from the elevator control unit 120, dispatches workers to carry out recovery work depending on the situation. Although Fig. 1 shows an example in which the control system 200 is connected to one building 100 via a closed network 500, in reality the control system 200 is a system that monitors elevators in multiple buildings. The control system 200 includes a control processing unit 210 , a cooperation processing unit 220 , a communication processing unit 230 , and a storage device 240 .

[0019] The control processing unit 210 communicates with the elevator control unit 120 in the building 100 via the communication processing unit 230 connected to the closed network 500, and receives abnormality reports and the like from the elevator control unit 120. The control processing unit 210 also enables an operator operating the control processing unit 210 to talk to passengers in the elevator 121 through an intercom installed in the elevator 121. Furthermore, the control processing unit 210 can obtain images captured by the camera 122 and display the situation when an abnormality occurs on a display unit (not shown).

[0020] The storage device 240 of the control system 200 stores images captured by the camera 122, information on the operation status of the elevator 121, and the like. The storage device 240 also stores information about workers who can perform work in each building 100. This worker information includes information such as a worker code, an email address of the worker, and an authentication card (security card) held by the worker.

[0021] The linking processor 220 of the control system 200 exchanges information with the building monitoring system 300 and the entrance / exit control system 400 via a closed network 501. The closed network 501 is a dedicated line that connects the control system 200, the building monitoring system 300, and the entrance / exit control system 400. This closed network 501 may use a closed network 500 or a wide area network 502 instead of a dedicated line. Details of information exchange using the linking processor 220 will be described later.

[0022] The control processing unit 210 of the control system 200 can be configured, for example, by a computer. That is, the control processing unit 210 is configured by a computer including a CPU (Central Processing Unit) 211 that controls arithmetic processing for various control processes, and a memory 212 having a work area that executes a program under the control of the CPU 211. Similarly, the control processing unit 310 of the building monitoring system 300 and the control processing unit 410 of the entrance / exit control system 400 described below can also be configured by a computer.

[0023] The building monitoring system 300 is a system that comprehensively monitors the status of the building 100, such as the occupancy status of each room, the air conditioning status, the on / off status of the lights, the power consumption, the security status, etc. Fig. 1 shows an example in which the building monitoring system 300 is connected to one building 100 via a wide area network 502, but in reality the building monitoring system 300 is a system that monitors a plurality of buildings.

[0024] The building monitoring system 300 includes a control processing unit 310 , a cooperation processing unit 320 , a communication processing unit 330 , and a storage device 340 . The control processing unit 310 communicates with a management terminal 150 installed in a manager's room or the like of the building 100 and various sensors (not shown) installed in the building 100 via a communication processing unit 330 connected to the wide area network 502. The control processing unit 310 also communicates with the entrance / exit management system 400 via the communication processing unit 330.

[0025] The control processing unit 310 determines the status of the building 100, such as the occupancy status of each room, the air conditioning status, the on / off status of the lights, the power consumption, the security status, etc., and stores the determined status of the building 100 in the storage device 340. In addition, the status of the building 100 determined by the control processing unit 310 is transmitted to the management terminal 150. The status of the building 100 received by the management terminal 150 is displayed on the display unit 151 of the management terminal 150. The cooperation processor 320 communicates with the cooperation processor 220 of the control system 200 via a closed network 501. Details of information exchange using the cooperation processor 320 will be described later.

[0026] The entrance / exit control system 400 generates authentication information required to control the locking and unlocking of the electric lock 141 of the building 100, and sends the generated authentication information to the entrance / exit control unit 140 of the building 100. The entrance / exit control unit 140 controls the locking and unlocking of the electric lock 141 based on the received authentication information. While Fig. 1 shows an example in which the entrance / exit control system 400 is connected to one building 100 via a wide area network 502, in reality the entrance / exit control system 400 is a system that monitors multiple buildings.

[0027] The entrance / exit control system 400 includes a control processing unit 410 , a cooperation processing unit 420 , a communication processing unit 430 , and a storage device 440 . The control processing unit 410 stores information about people permitted to enter the building 100 and identification information given to those permitted to enter in the storage device 440. Then, the control processing unit 410 transmits the identification information stored in the storage device 440 to the entrance / exit control unit 140 of the building 100 via the communication processing unit 430. The entrance / exit control unit 140 stores the received identification information in a storage unit (not shown), and performs processing to unlock the electric lock 141 when the stored identification information matches identification information read by a card reader or the like. The cooperation processor 420 communicates with the cooperation processor 220 of the control system 200 via a closed network 501. Details of information exchange using the cooperation processor 420 will be described later.

[0028] [Example of what to do when an elevator malfunction occurs] FIG. 2 is a state transition diagram showing an example of processing when an elevator malfunctions. First, when an abnormality (event occurrence) occurs in the elevator 121 of the building 100, the elevator control unit 120 detects the abnormality occurrence (step S11). Here, it is assumed that an event occurs in which a passenger is trapped in the car of the elevator 121. At this time, the elevator control unit 120 notifies the management system 200 of an abnormality report indicating the occurrence of the trapping (step S12). The control processing unit 210 of the control system 200, which has acquired this abnormality report, performs a process of detecting an abnormality (entrapment) in the elevator 121 of the building 100 based on the information on the abnormality report. When detecting an abnormality in the elevator 121, the control processing unit 210 selects a worker to perform recovery work in the building 100, and transmits an email requesting rescue work in the building 100 to a terminal (such as a smartphone) carried by the selected worker (step S13).

[0029] Furthermore, the control processing unit 210 of the management system 200 judges whether or not the building 100 that has sent the abnormality alert is a building in which the building monitoring system 300 and the entrance / exit management system 400 are installed. This judgment is made from information stored in the storage device 240 of the management system 200, but the control processing unit 210 may also inquire of the building monitoring system 300 and the entrance / exit management system 400 via the cooperation processing unit 220.

[0030] Here, when the building where the abnormality report was issued is a building in which the building monitoring system 300 and the entrance / exit management system 400 are installed, the control processing unit 210 reads out the relevant building information, the target elevator information, and the information of the worker selected in step S13 from the storage device 240 (step S14). Then, the control processing unit 210 transmits the read out building 100 information (building code), target elevator information (elevator code), and worker information (worker code) as transmission format information to the cooperation processing unit 420 of the entrance / exit management system 400 via the cooperation processing unit 220 (step S15). Note that when multiple workers (two, for example) are selected, the information of each worker is transmitted.

[0031] When the collaboration processing unit 420 of the entrance / exit management system 400 receives this information, the control processing unit 410 of the entrance / exit management system 400 extracts a route (traffic pattern) to reach the elevator 121 from the entrance / exit of the building 100 based on the acquired building code and information on the target equipment (elevator) (step S16). The control processing unit 410 also extracts information on the authentication card (the authentication card held by the worker) assigned to the worker with the acquired worker code (step S17). The information on the authentication card assigned to the worker is information acquired from the control system 200, but may be stored in the storage device 440 of the entrance / exit management system 400.

[0032] Then, the control processing unit 410 sets all the doors 142 existing in the passage pattern determined in step S16 as "passage permitted" for the authentication card extracted in step S17. Furthermore, the control processing unit 410 transmits the information of the authentication card set as "passage permitted" and the information of the doors to the entrance / exit control unit 140 of the building 100, and causes the "passage permitted" information of the worker's authentication card to be registered (step S18). The above processing is performed until the worker arrives at the building 100.

[0033] Then, when the worker who received the email in step S13 arrives at the building 100, the authentication card carried by the worker is read by a card reader located near the door 142 at the entrance (step S19). At this time, since the corresponding authentication card has already been registered as "permitted to pass," the entry / exit control unit 140 determines in the authentication process that passage is permitted, and unlocks the electric lock 141 (step S20). Here, when the entry / exit control unit 140 unlocks the door using the worker's authentication card, it records images (moving or still images) taken by a camera 143 near the authentication location (the unlocked door 142) before and after unlocking. The images recorded here may be images of the worker passing through all unlocked doors 142, or may only be images of the entrance door 142.

[0034] When the electric lock 141 is unlocked and an image is recorded in step S20, the entry / exit control unit 140 transmits the entry / exit record based on the worker's authentication card to the control processing unit 410 of the entry / exit management system 400 (step S21). At this time, images recorded before and after unlocking are also transmitted. The control processing unit 410 of the entrance / exit management system 400 transmits the images before and after unlocking received in step S21 from the cooperation processing unit 420 to the cooperation processing unit 320 of the building monitoring system 300 (step S22). Images received by the collaboration processing unit 320 of the building monitoring system 300 are recorded in the storage device 340 of the building monitoring system 300 and can be displayed, for example, on the display unit 151 of the management terminal 150 connected to the building monitoring system 300.

[0035] The worker then unlocks the door 142 by using the authentication card he carries, and arrives at the location where the elevator 121 that requires rescue work is installed. The worker then opens the hatch door (landing door for rescue) of the elevator 121 in question, and starts the rescue work and recovery work (step S23). Here, when the elevator control unit 120 detects that the worker has started work, it records an image from the camera 122 installed in the work location, such as the landing of the elevator 121 (step S24).

[0036] The image recorded in step S24 is transmitted to the cooperation processing unit 320 of the building monitoring system 300 via the control system 200 (step S25). The image transmitted to the building monitoring system 300 is recorded in the storage device 340 and can be displayed, for example, on the display unit 151 of the management terminal 150 connected to the building monitoring system 300.

[0037] [Example of how to process elevator restoration] FIG. 3 is a state transition diagram showing an example of processing when rescue and recovery work for the elevator 121 by workers is completed. First, assume that rescue and recovery work is completed using the elevator 121 of the building 100 (step S31). Upon completion of this work, the worker closes the hatch door that was open for the work (step S32). When the elevator control unit 120 detects that the hatch door has been closed, it records the image captured by the camera 122 at the landing where the relevant hatch door is installed (step S33). The image recorded in step S33 is transmitted to the cooperative processing unit 320 of the building monitoring system 300 via the control system 200 (step S34).

[0038] Furthermore, the elevator control unit 120 notifies the management system 200 of the confinement recovery of the elevator 121 (step S35). The control processing unit 210 of the management system 200 that has received this information on the confinement recovery determines whether or not the building 100 in which the recovered elevator 121 is installed is the building in which the building monitoring system 300 and the entrance / exit management system 400 are installed. If the building is one in which the building monitoring system 300 and the entrance / exit management system 400 are installed, the control system 200 reads out information about the worker who performed the corresponding recovery work from the storage device 240 (step S36).Then, the control system 200 transmits the read information about the building 100 (building code), information about the target elevator (elevator code), and worker information (worker code) as transmission format information to the cooperation processing unit 420 of the entrance / exit management system 400 via the cooperation processing unit 220 (step S37).

[0039] When the collaboration processing unit 420 of the entrance / exit management system 400 receives this information, the control processing unit 410 extracts a route (traffic pattern) to reach the elevator 121 from the entrance / exit of the building 100 based on the acquired building code and information on the target equipment (elevator) (step S38). Furthermore, the control processing unit 410 extracts information on the authentication card (the authentication card possessed by the worker) assigned to the worker with the acquired worker code (step S39).

[0040] Then, the control processing unit 410 changes all doors 142 present in the passage pattern determined in step S38 from "passable" to "non-passable" for the authentication card extracted in step S39, and transmits information about the authentication card and the doors that have been marked "non-passable" to the entry / exit control unit 140 of the building 100 (step S40). The entry / exit control unit 140 of the building 100 may change the corresponding authentication card to be unpassable, for example, after a certain time has elapsed since the recovery in step S31, so as to ensure time for the worker to leave the building 100. Alternatively, if unlocking of the locked door 142 is not required when leaving the building 100, the card may be immediately registered as unpassable.

[0041] [Example of display on building management terminal] The building monitoring system 300 is configured to record an image when a worker unlocks the entrance door 142 with an authentication card and passes through the door. The recorded image at this time can be displayed on the display unit 151 of the management terminal 150 installed in the building 100, for example. 4, the display unit 151 displays an image (a still image or a video of about a few seconds) of when the worker passes through the door 142 and the date and time of passage. This allows the manager of the building 100 to confirm that the worker has passed through the door 142 that has been locked by security processing. Here, an image is displayed when a worker passes through the locked door 142, but the control system 200 may also send recorded images of the elevator 121 during recovery work to the building monitoring system 300 and display them on the display unit 151 of the management terminal 150.

[0042] In addition, when the entrance / exit management system 400 sets a worker's authentication card to be passable, or when the corresponding authentication card is set to be passable, the management terminal 150 may display the respective settings on the display unit 151 or the like so that the building manager can check them.

[0043] As described above, according to the elevator management system of this example, when an event such as a trapped-in failure occurs in the elevator 121 and it becomes necessary to dispatch a worker, the entrance / exit management system 400 automatically registers the passability of the worker's authentication card in response to an instruction from the control system 200. This allows the worker to immediately enter the building 100 where the work is being carried out and arrive in front of the elevator 121 where the work will be carried out. This reduces the travel time from the worker's arrival at the site to the corresponding location, which leads to ensuring the quality and time of work that requires immediate attention, such as a trapped-in failure, and makes it possible to provide high-quality maintenance services.

[0044] Furthermore, according to the elevator management system of this example, after the recovery work is completed, the worker's authentication card is changed to an unpassable state, thereby preventing the door from being unlocked for purposes other than the recovery work, thereby ensuring proper security for the building 100.

[0045] In addition, in this example, when the door 142 is unlocked with the worker's authentication card, an image of the door 142 is recorded and can be displayed on the management terminal 150 or the like, so the manager of the building 100 can confirm from the recorded image that the worker has entered the building 100. Therefore, the manager of the building 100 can confirm that security processing is being performed appropriately.

[0046] [Variations] It should be noted that the embodiment examples described so far have been described in detail in order to explain the present invention in an easily understandable manner, and are not necessarily limited to those having all of the configurations described. For example, in the building 100, both the entrance and the hallway doors 142 are locked with electric locks 141, but the invention can also be applied to a case in which the entrance is not locked and only the door 142 in the middle of the hallway where the elevator 121 is installed or in a room is locked with an electric lock 141.

[0047] In addition, in the process of Figure 2, the entrance / exit management system 400 registers the passable information on the worker's authentication card in response to instructions from the elevator control system 200. At this time, the entrance / exit management system 400 may also send information requesting consent to the management terminal 150 of the building 100, and register the passable information on the worker's authentication card after consent from the management terminal 150. Alternatively, the entrance / exit management system 400 may automatically register the passage of elevator workers only in the case of buildings that have been set up in advance with the building 100 manager to allow their passage, and may not automatically register workers in buildings 100 that have been set up to not allow automatic registration of workers.

[0048] In the above embodiment, the countermeasure for the case where an elevator entrapment failure occurs has been described, but the same countermeasure is possible for the occurrence of other events such as elevator failure, etc. However, it is possible to register passable information on the authentication card of the worker only in the event of a highly urgent event such as an entrapment failure or a stop due to an earthquake, and not to perform the process of allowing the authentication card of the worker to pass in the event of an event that does not affect operation, such as a failure of some buttons in the elevator car.

[0049] Also, the use of an authentication card to unlock the electric lock 141 is one example, and for example, when a PIN code or the like is entered near the electric lock 141 to unlock it, the PIN code required for unlocking may be sent to a terminal carried by the worker instead of setting passable information. Alternatively, in a configuration in which the electric lock 141 is unlocked by facial recognition, a facial image of the worker may be registered in the entry / exit control unit 140.

[0050] Also, the building monitoring system 300 and the entrance / exit control system 400 are described as systems for managing multiple buildings, but each may be a system constructed individually for each building 100. Furthermore, the building monitoring system 300 and the entrance / exit control system 400 may be integrated into a single system.

[0051] 1 shows only the control lines and information lines that are considered necessary for explanation, and not all control lines and information lines are necessarily shown in the product. In reality, it may be considered that almost all components are connected to each other. Also, configuring the control processing units 210, 310, 410 of each system (control system 200, building monitoring system 300, entrance / exit control system 400) with a computer is just one example, and for example, part or all of the processing may be configured with hardware such as an FPGA (Field-Programmable Gate Array) or an ASIC (Application Specific Integrated Circuit).
