Description

The present invention relates to an elevator position specifying system and an elevator position specifying method.

Elevators and other elevators are monitored by a monitoring center operated by a maintenance company, and when any abnormality or failure occurs, maintenance personnel are dispatched according to instructions from the monitoring center.
One of the measures to be taken when an elevator is abnormal is to rescue passengers when they are trapped in the elevator car. That is, in the event of a disaster such as an earthquake, or in the event of an elevator failure or control system abnormality, passengers may be trapped in the elevator car. However, there are many cases in which it is not easy for the monitoring center or building manager to confirm that passengers are trapped in the elevator car.

As a technology to deal with the problem of confining passengers in the elevator car, a system has been proposed that makes it possible to check the image of the camera installed in the elevator car at the elevator landing and notify the concerned parties when an elevator abnormality occurs. (See, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2009-51641

Conventionally, if an abnormality occurs in which the elevator car door does not open and the building manager or the like contacts the monitoring center by telephone, etc., there is a possibility that passengers are trapped inside the elevator car. , The monitoring center dispatches maintenance personnel to the relevant elevator.

That is, the monitoring center that has been contacted asks the contact person for the name of the building where the elevator in which the abnormality has occurred is installed, and identifies the site. However, depending on the building, a large number of elevators may be installed, and there is a problem that it is difficult to accurately inform which unit has an abnormality when a telephone call is made.

Specifically, in many cases, a tag with an identification number for identifying the unit is posted in the elevator car, and when the monitoring center is contacted by the intercom in the car. Can identify the machine with the abnormality by asking for the identification number.
On the other hand, there is usually no tag with such an identification number on the landing side of the elevator, and when contacting from the building side, it is possible to know at which unit the passengers may be trapped. There are many cases where it is difficult to identify at the monitoring center.

If the unit in which the abnormality occurred cannot be identified, the monitoring center will take time and effort to identify the unit in which the abnormality has occurred, and problems such as delay in dispatching maintenance personnel will occur. It ends up. In addition, if the unit in which the abnormality occurred cannot be identified accurately, the building will send maintenance personnel to the elevator due to the automatic abnormality detection function provided by the control device installed in the elevator. It is possible that another maintenance worker will be dispatched by contact.

It is an object of the present invention to provide an elevator position specifying system and an elevator position specifying method capable of reliably specifying the reporting position when reporting an elevator such as an elevator.

In order to solve the above problems, for example, the configuration described in the claims is adopted.
The present application includes a plurality of means for solving the above problems. For example, the elevator position specifying system of the present invention has a communication unit that receives a report from a customer terminal and a landing for an elevator that monitors. Site estimation to specify the position of the target elevator by comparing the landing image storage unit that stores the images of the above, the image added to the report received by the communication unit, and the landing image accumulated by the landing image storage unit. It is provided with a unit and a monitoring information generation unit that generates monitoring information of an elevator whose position is specified by a site estimation unit and transmits it to a terminal of a monitoring center or a terminal of a worker.

According to the present invention, when a report is made from the elevator landing using a customer terminal, the position of the failed elevator can be specified by using the image of the landing added to the report, and the monitoring center side can identify the position of the failed elevator. It will be possible to quickly and accurately identify the elevator in which a failure has occurred. Therefore, according to the present invention, it becomes possible to promptly instruct measures such as dispatching workers.
Issues, configurations and effects other than those described above will be clarified by the description of the following embodiments.

Hereinafter, an example of an embodiment of the present invention (hereinafter referred to as “this example”) will be described with reference to the accompanying drawings.

[System configuration example]
FIG. 1 shows the overall configuration of the elevator position specifying system of this example.
The elevator position identification system of this example is applied to a monitoring system (hereinafter, also referred to as "monitoring system" of this example) that remotely and comprehensively monitors an elevator (here, an elevator) installed in a building or the like. be. That is, as shown in FIG. 1, a monitoring system 100 is installed, and the monitoring system 100 communicates with a monitoring device 220 that directly monitors the elevator 210 via a communication network 91 to monitor the state of the elevator 210. do. Here, the place where the elevator 210 and the monitoring device 220 are installed is referred to as a field work unit 200. Further, although only one elevator 210 is shown in FIG. 1 for the sake of simplicity, the monitoring system 100 actually monitors a large number of elevators via the communication network 91.

A monitoring terminal 410 included in the monitoring center 400 is connected to the monitoring system 100. The monitoring terminal 410 displays the status of each elevator 210 and the like. Further, when calling from the intercom installed in the car of the elevator 210, the operator (observer) can make a call using the monitoring terminal 410. Further, the monitoring terminal 410 can also make a call with the customer terminal 310 described later of the customer 300.

Further, the monitoring system 100 of this example can respond to inquiries from the customer terminal 310 possessed by the customer 300. The customer 300 here indicates either the case of a manager of a building or facility in which the elevator 210 is installed, or the case of a general user of the elevator 210.
The customer terminal 310 communicates with the monitoring system 100 via the communication network 92.
In the case of this example, when the manager of the building or facility or the user of the elevator discovers the failure of the elevator outside the car (landing), the occurrence of the failure can be reported by using the customer terminal 310. It has become like.

Further, the monitoring system 100 can instruct the worker terminal 510 possessed by the local worker 500 via the communication network 93 to perform maintenance work on the elevator.
In the configuration shown in FIG. 1, the communication networks 91, 92, and 93 are separate networks, but as these communication networks 91, 92, and 93, a common communication network such as a public telephone line is used. May be good.

Next, the configuration of the monitoring system 100 will be described.
The monitoring system 100 includes a failure monitoring server 110, a WEB server 120, a wide area disaster system 130, a site estimation unit 140, a monitoring information generation unit 150, an image analysis unit 160, a site information storage unit 170, and an image information storage unit 180.

The failure monitoring server 110 communicates with the monitoring device 220 of the on-site work unit 200, acquires failure information when the elevator 210 fails, and manages the acquired failure information. This failure information also includes information on a state in which the elevator 210 cannot be operated due to factors other than the failure. Further, the management of the failure information in the failure monitoring server 110 is performed independently of the processing in the WEB server 120 described below.

The WEB server 120 includes a position information control unit 121, an image information control unit 122, and a communication unit 123. When the WEB (web) page prepared by the WEB server 120 is accessed from the customer terminal 310 via the Internet, the communication unit 123 performs communication processing with the customer terminal 310 and performs communication processing with the customer terminal 310, such as information input to the WEB page. Is obtained from the customer terminal 310. The information acquired here includes the position information of the customer terminal 310 itself and the image information taken by the camera built in the customer terminal 310.

It is conceivable that the access destination information such as the address of the WEB page accessed by the customer terminal 310 may be indicated by the information posted in the car, the QR code having the connection destination information, or the like. Alternatively, the corresponding WEB page may be accessed via the site of the company that operates the monitoring system 100. On the WEB page, the customer 300 inputs necessary information while checking the display on the WEB page. The input request at this time may be, for example, a conversational response system such as a chatbot, or one that allows the user to select from items prepared in advance.

The position information control unit 121 acquires the position information included in the information acquired by the communication unit 123 from the customer terminal 310.
The image information control unit 122 acquires image information included in the information acquired by the communication unit 123 from the customer terminal 310.
The position information acquired by the position information control unit 121 and the image information acquired by the image information control unit 122 are sent to the site estimation unit 140.

When the WEB server 120 accesses a predetermined WEB page from the customer terminal 310 via the communication unit 123, the WEB server 120 displays a guide screen on the screen of the customer terminal 310 that has been accessed. Then, the customer 300 is urged to input the information necessary for specifying the position of the elevator 210 on the screen of the customer terminal 310.

The wide area disaster system 130 acquires information on wide area disasters such as flooding caused by an earthquake or tsunami via the Internet or the like.
The site estimation unit 140 identifies the position (site position) of the elevator 210 informed by the customer terminal 310 using the position information and the image information (site estimation process). At this time, the site estimation unit 140 reads out the site information stored in the site information storage unit 170 and the image information stored in the image information storage unit 180, and estimates the site position.

The site information storage unit 170 holds a position information database that stores position information about all elevators 210 monitored by the monitoring system 100. The location information stored in the location information database includes the absolute coordinate position indicating the location where each elevator is installed and the detailed address, as well as the names of the buildings and facilities installed, nearby stations and intersections. , Keywords that can be used when specifying the location such as the name of a building that becomes a landmark in the neighborhood are also included.

Then, the site estimation unit 140 compares the position information stored in the position information database with the position information acquired by the position information control unit 121, and estimates the position of the site where the customer terminal 310 has reported.
The image information storage unit 180 holds an image information database that stores image information of all the elevators 210 that are monitored by the monitoring system 100 (image storage process). Here, the image information of the landing is an image (still image) of the door of the landing, and is, for example, an image of the door of the representative floor such as the landing on the first floor and its surroundings. Alternatively, the images of the landings on all the stop floors may be used as the image information of the landings.

When a plurality of units are installed in one building, images of the landings on the representative floors or all floors of each unit are stored in the image information storage unit 180. In the landing where the brightness and the like change depending on the time zone, the conditions are different (the shooting time and the like are different) in one landing, so that a plurality of images may be accumulated according to the time zone.

The image information stored in the image information storage unit 180 is read out by the image analysis unit 160, and is compared with the image information transmitted from the customer terminal 310 by the image analysis unit 160. Based on the comparison result in the image analysis unit 160, the site estimation unit 140 determines at which location the image transmitted from the customer terminal 310 is the landing image. When the site estimation unit 140 estimates the site from an image or the like, it also refers to the information of the elevator 210 in which the failure occurred acquired by the failure monitoring server 110 and the information of the disaster occurrence area acquired by the wide area disaster system 130. Will be done.

When the position of the elevator 210 notified from the customer terminal 310 is specified by the site estimation unit 140, the site estimation unit 140 sends information on the specified position to the monitoring information generation unit 150.
The monitoring information generation unit 150 acquires failure information and disaster occurrence information regarding the elevator 210 at the specified position from the failure monitoring server 110 and the wide area disaster system 130, and monitors monitoring information showing details such as the failure status of the corresponding elevator 210. To generate. Then, the monitoring information generation unit 150 sends the generated monitoring information to the monitoring terminal 410 of the monitoring center 400 and displays it on the monitoring terminal 410.
If there is a local worker 500 in the vicinity of the elevator 210 whose position is specified, the monitoring information generated by the monitoring information generation unit 150 is sent to the worker terminal 510 of the local worker 500, and the local worker 500 is sent. Instruct the restoration work by.

[Hardware configuration example]
FIG. 2 shows an example of hardware configuration when each part of the monitoring system 100 shown in FIG. 1 is configured by a computer device.
The computer device 10 shown in FIG. 2 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, and a RAM (Random Access Memory) 13, respectively, connected to the bus. Further, the computer device 10 includes a non-volatile storage 14, a network interface 15, an input device 16, and a display device 17.

The CPU 11 is an arithmetic processing unit that reads out from the ROM 12 the program code of the software that realizes each processing unit 110 to 160 included in the monitoring system 100 and executes it.
Variables, parameters, and the like generated during the arithmetic processing are temporarily written in the RAM 13.

For the input device 16, for example, a keyboard, a mouse, or the like is used.
The display device 17 is, for example, a liquid crystal display monitor, and the display device 17 displays the result of calculation processing executed by the computer device.

For the non-volatile storage 14, for example, a large-capacity information storage medium such as an HDD (Hard Disk Drive) or SSD (Solid State Drive) is used. A program that executes a processing function of each part of the monitoring system 100 is recorded in the non-volatile storage 14. The non-volatile storage 14 is also used as the site information storage unit 170 and the image information storage unit 180, and the location information database and the image information database are recorded.

For the network interface 15, for example, a NIC (Network Interface Card) or the like is used. The network interface 15 transmits and receives various information to and from the outside via a LAN (Local Area Network), a dedicated line, and the like.

It should be noted that each processing unit of the monitoring system 100 is configured by the computer device shown in FIG. 2 as an example, and may be configured by other arithmetic processing devices other than the computer. For example, a part or all of the functions performed by the monitoring system 100 may be realized by hardware such as FPGA (Field Programmable Gate Array) or ASIC (Application Specific Integrated Circuit).

[Process flow when accessing from customer terminal]
FIG. 3 is a flowchart showing a processing flow in the monitoring system 100 when there is an access from the customer terminal 310.
First, the customer terminal 310 accesses the site (WEB page) of the registered address (step S11). Instead of accessing the WEB page, an application program for accessing the WEB server 120 may be prepared and the application program may be implemented in the customer terminal 310 in advance.

The customer terminal 310 that has accessed the WEB page executes the input of the location information based on the instruction on the screen on the WEB page (step S12). The position information is input by a position positioning function such as GPS (Global Positioning System) built in the customer terminal 310, and if the current position can be detected, the detected position information is used as it is. If the current position cannot be determined, the address, building name, etc. are input on the WEB page. Even if the current position cannot be determined and the input of location information such as an address is not completed, the process proceeds to the next step.

Then, on the WEB page displayed on the customer terminal 310, a reference image showing how to take the landing image transmitted from the WEB server 120 is displayed (step S13).
FIG. 4 shows an example of a reference image showing a shooting guide, which is a method of shooting a landing image, which is displayed when the customer terminal 310 accesses the WEB server 120.
In the reference image shown in FIG. 4, the door of the elevator landing is shown almost in front, and various guidance indicator lights and a car call button on or beside the door are included.

In addition, in the reference image, the characters are used as a shooting guide to announce points to be noted when shooting. Specifically, along with the arrow indicating the width at the time of shooting, "1. Adjust the width so that the hole button can be inserted from the end of the car. * The hole button may be on the left side." Is displayed.
Also, along with the arrow indicating the vertical width at the time of shooting, "2. Adjust the height so that it fits from the destination floor display at the top of the car to the bottom of the car. * If there is no destination display, from the top of the car Please adjust up to the bottom edge. "Is displayed.
Furthermore, along with the arrow indicating the diagonal line at the time of shooting, "3. Adjust so that the entire car is as large as possible." Is displayed.

After confirming the display of these shooting guides on the customer terminal 310, the customer 300 uses the camera function of the customer terminal 310 to shoot the landing of the elevator 210 in which the failure has occurred, and inputs the shot image on the WEB page. (Step S14).
The information input from the customer terminal 310 is transmitted to the WEB server 120 and extracted by the WEB server 120 (step S15). That is, the position information control unit 121 acquires the position information, and the image information control unit 122 acquires the image information.

When the position information and the image information are acquired by the position information control unit 121 and the image information control unit 122, the site estimation unit 140 performs a process of identifying the elevator at the information site using the position information and the image. Here, the site estimation unit 140 performs a process of narrowing down the candidate elevators based on, for example, the position information, and the landing image of the narrowed down candidate elevators is read out from the image information storage unit 180. Then, the image analysis unit 160 compares the candidate landing image with the landing image taken by the customer terminal 310, and identifies the elevator of the candidate landing image having the highest degree of matching as the on-site elevator 210 (). Image analysis processing).
When the site elevator 210 is specified by the site estimation unit 140, the information of the specified elevator 210 is sent to the monitoring information generation unit 150.

Returning to the description of the flowchart of FIG. 3, the monitoring information generation unit 150 determines whether or not the elevator 210 notified by the customer terminal 310 can be identified from the position information and the image information (step S16). If it is determined in step S16 that the elevator 210 can be specified (YES in step S16), the monitoring information generation unit 150 provides information about the current state of the elevator 210 at the specified site to the failure monitoring server. Obtained from 110 and the wide area disaster system 130 (step S17). Then, from the current state information of the elevator 210 at the specified site, the monitoring information generation unit 150 determines whether or not a failure or passenger confinement has occurred in the corresponding elevator 210 (step S18).

When it is determined in step S18 that a failure has occurred or passengers have been confined (YES in step S18), the monitoring information generation unit 150 is the monitoring terminal 410 of the monitoring center 400, and the intercom in the corresponding car. It is determined whether or not the call in is received (step S19).
If it is determined in step S19 that the call on the intercom has been received (YES in step S19), the monitoring information generation unit 150 creates status data for the failure of the corresponding elevator 210 (step S20). Then, the monitoring information generation unit 150 sends the created status data to the WEB server 120, and displays information on the failure acceptance status and the confinement occurrence status on the screen of the customer terminal 310 (step S21).

Further, when it is determined in step S18 that no failure has occurred and no passengers have been confined (NO in step S18), the monitoring information generation unit 150 determines the on-site response status and the current status. Create status data that shows the status (step S23). Then, the monitoring information generation unit 150 displays the status based on the created status data on the customer terminal 310, displays the status on the monitoring terminal 410 of the monitoring center 400, and further dispatches the local worker 500. If so, the status is also displayed on the worker terminal 510 (step S24).

Further, when it is determined in step S16 that the elevator 210 notified by the customer terminal 310 cannot be identified from the position information and the image information, the monitoring information generation unit 150 has already performed the position and the like twice on the customer terminal 310. It is determined whether or not the input has been made (step S25). When it is determined in step S25 that the position and the like have not been input twice (NO in step S25), the WEB server 120 generates a question useful for identifying the site and generates a customer. The generated question text is displayed on the screen of the terminal 310 (step S26). The generation of this question is performed by an instruction from the monitoring information generation unit 150.

The questions here are, for example, "What floor is the current floor?", "What is the name of the building?", "What is the name of the station around the site?", "What is the name of the surrounding building?", ""What is the name of the tenant in the building?", "Please send me a photo from another angle" and so on.
These questions are prepared in advance by, for example, the monitoring information generation unit 150, and one of the questions is selected according to the estimation situation in the site estimation unit 140. Alternatively, these questions may be sent to the customer terminal 310 in a list, and the customer 300 may select and input one of the items.

The customer 300 who confirmed the question notified in step S26 inputs additional information so as to answer the question text on the customer terminal 310 (step S27), and the site estimation unit after adding the additional information. The position specifying process in 140 is performed, and the process returns to the determination in step S16. By inputting the additional information, the site candidates can be narrowed down by using the input information (keywords such as the building name) at the time of the position specifying process in the site estimation unit 140.

If it is determined in step S25 that the second input has already been performed (YES in step S25), the WEB server 120 connects the customer terminal 310 to the monitoring terminal 410 of the monitoring center 400 (step S22).
Further, even when the call from the intercom is not received in step S19 (NO in step S19), the WEB server 120 connects the customer terminal 310 to the monitoring terminal 410 of the monitoring center 400 (step S22). By connecting the customer terminal 310 and the monitoring terminal 410 in step S22, the operator of the monitoring center 400 and the customer 300 can directly talk to each other.

As described above, according to the monitoring system 100 of this example, when the customer 300 finds a failure of the elevator 210, the customer terminal 310 is used to access the WEB server 120 and operate according to the guidance display for monitoring. The site can be specified on the system 100 side. That is, on the monitoring system 100 side, the landing images of all the elevators that are being managed are saved, and the landing image of which elevator is specified by image analysis by comparison with the landing image transmitted from the customer terminal 310. become able to. Therefore, even if the elevator identification number written in the car cannot be confirmed due to a situation such as the car door not opening, the customer terminal 310 will definitely fail. Elevator 210 can be identified. Since the failure site of the elevator can be identified, it is possible to promptly contact the local worker 500.

Further, when the site estimation unit 140 estimates the site, it becomes a candidate by using the position information of the customer terminal 310 and keywords (address, building name, neighboring building name, etc.) necessary for determining the position. Since the elevator is squeezed, the burden during image analysis can be reduced. In particular, when the site cannot be specified by the information regarding the position initially input, the customer terminal 310 is made to input additional information, so that the candidates can be narrowed down satisfactorily.

In addition, the customer terminal 310 only needs to take a picture of the landing based on the instructions on the WEB screen or input additional information for specifying the position, and it is reliable even if the exact address is not remembered. You will be able to report about the malfunctioning elevator 210.
Furthermore, if the site cannot be identified by the landing image or additional information, the operator of the monitoring center 400 is connected to make a call, so that even if the monitoring center 400 cannot identify the site by image analysis, it can be dealt with accurately. It will be like.

In addition, the customer terminal 310 that reports a failure or the like only needs to access a specific WEB page, and simply posts the connection destination information such as a QR code (registered trademark) on the Internet such as a smartphone. Anyone with a connectable terminal will be able to make a report.
Alternatively, the specific WEB page for reporting a failure or the like may be migrated from the top page of the home page of the company (elevator manufacturing company) that operates the monitoring system 100. By doing so, the customer 300 can confirm the company name of the elevator, easily reach the corresponding WEB page by searching for the company name, and make a report.

[Modification example]
The present invention is not limited to the above-described embodiment, and includes various modifications. For example, the above-described embodiment has been described in detail in order to explain the present invention in an easy-to-understand manner, and is not necessarily limited to the one including all the described configurations.

For example, in the process shown in the flowchart of FIG. 3, the customer is made to input the additional information up to twice, and after that, the operator of the monitoring center is connected, but the number of times the additional information is input is twice. It is an example, and may be another number of times.

Further, when the image analysis unit 160 selects a candidate image, keywords such as location information, a building name, and an address are used, but the candidate image may be selected from other information. For example, based on the information from the failure monitoring server 110, the monitoring information generation unit 150 acquires the information of the elevator in failure at the time of receiving a report, and preferentially visits the site from the landing image of the elevator in failure. You may try to find it.

Further, in the above-described embodiment, an example applied to an elevator is used as an example of an elevator. On the other hand, the present invention can be applied to other elevators (cargo lifts, escalators, etc.). That is, it can be applied to specify each site by accumulating the landing image (image of the installation location) of each elevator and comparing it with the image transmitted from the customer terminal.

Further, in the configuration diagram of FIG. 1, only the control lines and information lines considered to be necessary for explanation are shown, and not all the control lines and information lines are necessarily shown in the product. In practice, it can be considered that almost all configurations are interconnected.
Further, the order of processing shown in the flowchart shown in FIG. 3 is also shown as an example, and the order of each step may be changed or a plurality of steps may be executed at the same time as long as the processing result does not change. May be good.

Further, the configuration described in the embodiment may be realized by software by the processor interpreting and executing a program that realizes each function. Information such as a program that realizes each function can be placed in a memory, a hard disk, a recording device such as an SSD (Solid State Drive), or a recording medium such as an IC card, an SD card, or an optical disk.
