Description

The present invention relates to a device identification system, and is suitable for application to, for example, a device identification system that specifies a device inquired by an inquirer.

Conventionally, when an elevator breaks down, a customer calls a call center to request consultation and restoration work. In that case, in order to identify the elevator, the power receiving side needs to identify the elevator to be inquired by asking some questions to the customer.

In recent years, a method for identifying an elevator has been proposed by attaching a two-dimensional code for identifying the elevator in addition to the contact information to the call center in the car (see Patent Document 1).

JP-A-2007-106520

However, in the technique described in Patent Document 1, it is necessary to prepare and manage two-dimensional codes for the number of maintenance units, which requires a very complicated operation.

The present invention has been made in consideration of the above points, and an object of the present invention is to propose a device identification system capable of identifying a device to be inquired without preparing two-dimensional codes for the number of maintenance units.

In order to solve such a problem, in the present invention, the device identification system for specifying the device inquired by the inquirer, and the interface unit provides information related to the position of the device from the terminal of the inquirer who inquires about the device. It is specified by the first narrowing-down unit, which is acquired through the device and identifies the devices around the position, the feature information indicating the characteristics of the managed device stored in the storage unit, and the first narrowing-down unit. A second narrowing-down unit for specifying a device that matches the feature information of the device and an output section for outputting information related to the device specified by the second narrowing-down unit are provided.

According to the above configuration, the device to be inquired is specified from the position information that can be acquired from the terminal possessed by the inquirer and the feature information of the device used in the existing operation. Therefore, for example, a two-dimensional code unique to the device is specified. The device to be inquired can be specified without providing.

According to the present invention, the device to be inquired can be appropriately specified.

(1) First Embodiment In FIG. 1, 100 indicates a device identification system according to the first embodiment as a whole.

FIG. 1 is a diagram showing an example of a configuration related to the device identification system 100.

The device identification system 100 includes a web server 110, a narrowing unit 120, a storage unit 130, a monitoring server 140, and a wide area disaster system 150, and includes an inquirer 160, a local 170, a call center 180, and a local worker. It is connected so that it can communicate with the outside such as 190.

For example, the device identification system 100 is communicably connected to the terminal 161 of the inquirer 160 via the network (communication line) 101. The inquirer 160 is a person who makes an inquiry about the device 171 such as an elevator or an escalator installed in the local 170, and may be, for example, a person (administrator) who manages the device 171 or uses the device 171. It may be a person (user) who does. The terminal 161 is a mobile phone, a smartphone, a tablet terminal, a laptop computer, or the like. For example, when an abnormality or failure occurs in the device 171 the inquirer 160 makes an inquiry using the terminal 161 that can be connected to the device identification system 100.

Further, for example, the device identification system 100 is communicably connected to the monitoring device 172 provided at the site 170 via the network 102. The site 170 is provided with equipment 171 (for example, an elevator such as an elevator or an escalator) and a monitoring device 172 for monitoring the state of the equipment 171. For example, when a failure (abnormality) occurs in the device 171, the failure information of the device 171 is transmitted from the monitoring device 172 to the monitoring server 140.

Further, for example, the device identification system 100 is communicably connected to the call center 180. The call center 180 is provided with a terminal 181 that the operator uses to respond to inquiries. The terminal 181 is a telephone, a personal computer, a tablet terminal, a laptop computer, or the like.

Further, for example, the device identification system 100 is communicably connected to the terminal 191 of the local worker 190 via the network 103. The terminal 191 is a mobile phone, a smartphone, a tablet terminal, a laptop computer, or the like.

The web server 110 of the device identification system 100 receives an inquiry from the inquirer 160.

The web server 110 is a control device such as a CPU (Central Processing Unit), a storage device such as a RAM (Random Access Memory), a ROM (Read Only Memory), an HDD (Hard Disk Drive), and communication such as a NIC (Network Interface Card). A computer that includes a device. The web server 110 is, for example, a web server that provides display information of objects such as HTML (Hyper Text Markup Language) and images to a web browser of client software provided in the terminal 161 of the inquirer 160. The web server 110 provides a service to the inquirer 160, performs input / output processing for identifying the device 171 and the like.

More specifically, the web server 110 includes an interface unit 111, a position information control unit 112, and a narrowing information control unit 113.

The interface unit 111 is an interface with the terminal 161 and receives (inputs) information from the terminal 161 and transmits (outputs) information to the terminal 161 via the network 101. The interface unit 111 may be, for example, an automatic conversation program (so-called chatbot) that communicates in real time.

The position information control unit 112 controls for inputting the position information. For example, the position information control unit 112 analyzes the position information input from the interface unit 111 and processes it into data that can be compared with the position information of the device 171 managed by the device identification system 100. The position information input by the inquirer 160 is basically the position information of GPS (Global Positioning System) that can be acquired by the terminal 161. However, if the GPS position information cannot be acquired, if there is no function to acquire the GPS position information, or if the inquirer 160 does not allow the transmission of the GPS position information to the device identification system 100, the surroundings will be described later. Location information is estimated from the building name, address, etc.

The narrowing down information control unit 113 controls the narrowing down of the inquiry device 171. For example, the narrowing down information control unit 113 converts the feature information received via the interface unit 111 into a data format that can be processed by the second narrowing down unit 122.

The functions of the web server 110 (interface unit 111, position information control unit 112, narrowing information control unit 113, etc.) are realized, for example, by the CPU reading the program stored in the ROM into the RAM and executing it (software). It may be realized by hardware such as a dedicated circuit, or it may be realized by combining software and hardware. Further, a part of the function of the web server 110 may be realized by another computer capable of communicating with the web server 110.

The narrowing-down unit 120 is a computer including a control device such as a CPU, a storage device such as a RAM, a ROM, and an HDD, and a communication device such as a NIC.

The narrowing section 120 includes a first narrowing section 121, a second narrowing section 122, and an output section 123. The narrowing-down unit 120 narrows down using the position information related to the inquiry device 171 received by the web server 110 and various information stored in the storage unit 130.

For example, the first narrowing-down unit 121 acquires information relating to the position of the device 171 from the terminal 161 possessed by the inquirer 160 via the interface unit 111, and identifies the device 171 around the position.

In the second narrowing-down unit 122, for example, the feature information indicating the characteristics of the device 171 to be managed stored in the storage unit 130 and the feature information of the device 171 specified by the first narrowing-down unit 121 match. Identify device 171. The feature information indicating the features of the device 171 is information useful for distinguishing the device 171 from another device 171. The feature information includes specification information indicating the specifications of the device 171, failure information indicating whether or not the device 171 is out of order, state information indicating the state of the device 171 and the like.

The output unit 123 outputs output information. The output information is, for example, information (narrowing information) related to the device 171 narrowed down by the second narrowing unit 122. More specifically, the output unit 123 generates output information by associating the device 171 narrowed down by the second narrowing-down unit 122 with the status indicating the current status of the device 171 and is related to the device 171. Output information is transmitted to the system (terminal 161, terminal 181, terminal 191 and the like).

The function of the narrowing-down unit 120 (first narrowing-down unit 121, second narrowing-down unit 122, output unit 123, etc.) is realized, for example, by the CPU reading a program stored in the ROM into the RAM and executing it (software). It may be realized by hardware such as a dedicated circuit, or it may be realized by combining software and hardware. Further, a part of the function of the narrowing unit 120 may be realized by another computer capable of communicating with the narrowing unit 120.

The storage unit 130 is an external storage device such as a database server, a storage device, or an HDD connected to the narrowing-down unit 120.

The storage unit 130 contains the position information of the device 171 (FIG. 2), the specification information of the device 171 (FIG. 3), the failure information of the device 171 acquired from the monitoring server 140 (FIG. 4), and the device 171 acquired from the monitoring server 140. State information (Fig. 5), wide area disaster information acquired from the wide area disaster system 150 (Fig. 6), specific information generated from feature information (specification information and / or state information) (Fig. 7), etc. are stored. ..

A part or all of the information stored in the storage unit 130 may be stored in the storage device of the narrowing unit 120.

The monitoring server 140 manages failure information transmitted from the monitoring device 172. The monitoring server 140 manages the status of each device 171 and the current recovery status. For example, when a failure occurs in a certain device 171, the monitoring server 140 changes the response status (current status) such as whether the local worker 190 is responding or moving, and the current status of the device 171. The status information shown is managed.

The wide area disaster system 150 manages information on wide area disasters such as flooding caused by earthquakes and tsunamis.

The output information 800 is information related to the device 171 corresponding to the inquiry of the inquirer 160. For example, the output information 800 includes information such as the device ID 801 and the current status 802, and the failure content 803.

FIG. 9 is a diagram showing an example of a flowchart relating to a process for specifying the device 171 of the inquiry (device identification process). The device identification process is started when the terminal 161 accesses a website (inquiry site) for making an inquiry in response to an operation of the inquirer 160 (step S901).

Here, the inquiry site may be accessed by inputting the information of the access destination (for example, URL (Uniform Resource Locator)), or via the website of the company that maintains the device 171. You may. The access destination information may be information posted on the device 171 (for example, in the car), or may be a two-dimensional code having the access destination information.

In step S902, the interface unit 111 inputs the position information indicating the current position of the terminal 161 from the terminal 161. For example, the interface unit 111 receives the position information acquired by the GPS function of the terminal 161. At this time, the interface unit 111 may display a screen such as "May I send the location information for the inquiry" on the terminal 161 and accept the input of whether or not the location information can be transmitted from the inquirer 160. .. The interface unit 111 notifies the position information control unit 112 of the received position information, and the position information control unit 112 can process the received position information in the first narrowing unit 121 (for example, the same as the position information 200). Data format).

In step S903, the first narrowing-down unit 121 identifies the device 171 around the input position (extracts the peripheral device 171) based on the input position information. For example, the first narrowing-down unit 121 refers to the position information 200 and extracts the device ID 201 of the device 171 within a predetermined distance from the position of the input position information.

When a question regarding the position of the device 171 described later (for example, "Please tell me your current address") is asked, the first narrowing-down unit 121 may refer to the position-specific information described later, for example, as an interface unit. The position (for example, (211,111)) associated with the answer (for example, “Kanda Awajicho, Chiyoda-ku, Tokyo”) of the answer information received in 111 is specified as the position related to the inquiry device 171. For example, the location identification information includes information for asking a question about the location of the device 171 (current address, building name, information posted in the car, station name around the site, surrounding building name, customer number, etc.) and location. Information is linked and stored.

In step S904, the first narrowing-down unit 121 determines whether or not the device 171 can be extracted. When the first narrowing-down unit 121 determines that the device 171 can be extracted, the process is transferred to step S908, and when it is determined that the device 171 cannot be extracted, the process is transferred to step S905.

In step S905, the first narrowing section 121 determines whether or not there is a question regarding the position of the device 171. When the first narrowing-down unit 121 determines that there is a question regarding the position of the device 171, the process shifts to step S906, and when it is determined that there is no question regarding the position of the device 171, the device identification process ends. Here, when the first narrowing-down unit 121 determines that there is a question regarding the position of the device 171, the question regarding the position of the device 171 includes the current address, the building name, the bulletin board information in the car, the station name around the site, and the surroundings. Generate question information for questions that confirm one or more of the building name and customer number.

When all the questions regarding the position of the device 171 were asked by the first narrowing-down unit 121 (when it was determined that there was no question regarding the position of the device 171), the position could not be specified via the interface unit 111. The fact may be transmitted to the terminal 161.

In step S906, the narrowing down information control unit 113 transmits the question information generated by the first narrowing down unit 121 to the terminal 161 via the interface unit 111. In other words, the interface unit 111 requests the terminal 161 to input the position information. The interface unit 111 may respond in a conversational format such as a chatbot, or may display a display screen (for example, a check box) in a format for selecting an answer. ..

In step S907, the interface unit 111 inputs the position information (answer information) which is the answer to the question of the question information from the terminal 161 and shifts the process to step S903. For example, the interface unit 111 notifies the position information control unit 112 of the received position information, and the position information control unit 112 converts the received position information into a data format that can be processed by the first narrowing unit 121.

In step S908, the second narrowing-down unit 122 determines whether or not the specified device 171 is a device in a wide-area disaster area (whether or not it is in a wide-area disaster area). When the second narrowing-down unit 122 determines that it is in the wide area disaster area, it shifts the process to step S916, and when it determines that it is not in the wide area disaster area, it shifts the process to step S909.

For example, the second narrowing-down unit 122 acquires the wide-area disaster information 600 from the wide-area disaster system 150 and stores it in the storage unit 130, and among the devices 171 specified by the first narrowing-down unit 121, the device IDs match. If there is information in the wide area disaster area 602 that is "YES", it is determined that the information is in the wide area disaster area.

In step S909, the second narrowing-down unit 122 associates the device 171 identified by the first narrowing-down unit 121 with the presence or absence of a failure. For example, the second narrowing-down unit 122 acquires the failure information 400 from the monitoring server 140 and stores it in the storage unit 130, and for each device 171 identified by the first narrowing-down unit 121, there is a failure in which the device IDs match. The 402 is specified, and the device 171 is associated with the information "yes" or "no" of the failure presence / absence 402.

In step S910, the second narrowing-down unit 122 determines whether or not there is a malfunctioning device 171. When the second narrowing-down unit 122 determines that there is a failed device 171, the process is transferred to step S911, and when it is determined that there is no failed device 171, the process is transferred to step S916.

In step S911, the second narrowing-down unit 122 generates the specific information 700. For example, the second narrowing-down unit 122 excludes the non-failing device 171 from the specific target among the devices 171 specified by the first narrowing-down unit 121. Then, the second narrowing-down unit 122 reads the specification information 300 from the storage unit 130 for the specific target device 171 using the device ID of the specific target device 171 as a key, and acquires the state information 500 from the monitoring server 140. Generates specific information 700. The specific information 700 may be created by including other information such as contract information.

In step S912, the second narrowing-down unit 122 determines whether or not the inquiry device 171 can be specified (whether or not the specific target has been narrowed down to one). When the narrowing-down unit 120 determines that the device 171 can be specified, the process is transferred to step S916, and when it is determined that the device 171 cannot be specified, the process is transferred to step S913.

When a question (for example, is the device inquired about an elevator or an escalator?) Regarding the features (for example, "product type") described later is asked, for example, the second narrowing-down unit 122 is an interface unit. The feature information (for example, "escalator") indicating the feature included in the answer of the answer information received in 111 (for example, "the escalator") and the feature of the device 171 to be managed (for example, "the escalator") of the specific information 700. By comparing with the feature information (for example, "escalator", "elevator") indicating the feature information (for example, "escalator", "elevator"), the device (for example, the device 171 with the device ID "X0000010") whose feature information matches is specified.

In step S913, the second narrowing section 122 determines whether or not there is a question regarding the features of the device 171. When the second narrowing-down unit 122 determines that there is a question regarding the feature of the device 171, the process is transferred to step S914, and when it is determined that there is no question regarding the feature of the device 171, the process is transferred to step S918.

Here, when the second narrowing-down unit 122 determines that there is a question regarding the feature of the device 171, it confirms any one or more of the features (items) of the specific information 700 as a question regarding the feature of the device 171. Generate question information for a question. For example, the second narrowing-down unit 122 refers to the generated specific information 700, extracts different features (differences) between the devices 171 that cannot be specified, and serves as question information for asking the extracted features. Generate question information to confirm one or more of product type, maximum floor, ascending or descending, and current status.

When all the questions regarding the features of the device 171 are asked by the second narrowing-down unit 122 (when it is determined that there are no questions regarding the features of the device 171), the device 171 cannot be specified via the interface unit 111. The fact may be transmitted to the terminal 161.

In step S914, the narrowing down information control unit 113 transmits the question information generated by the second narrowing down unit 122 to the terminal 161 via the interface unit 111. In other words, the interface unit 111 requests the terminal 161 to input the feature information. The interface unit 111 may be a chatbot that responds in a conversational manner (narrows down in sequence), or displays a check box (display screen) prepared in advance (narrows down at once). It may be. An example of the chatbot format will be described later with reference to FIG.

In step S915, the interface unit 111 inputs the feature information (answer information) which is the answer to the question of the question information from the terminal 161 and shifts the process to step S912. For example, the interface unit 111 notifies the narrowing down information control unit 113 of the received feature information, and the narrowing down information control unit 113 converts the received feature information into a data format that can be processed by the second narrowing down unit 122.

In step S916, the output unit 123 generates output information.

For example, when the output unit 123 is determined to be a wide area disaster area in step S908, it indicates that it is a wide area disaster (for example, "Customer, are you okay? The elevator is stopped for a while due to the earthquake that occurred at what time and minute." The worker is heading there .... ") is generated as output information.

Further, for example, when it is determined in step S910 that there is no device 171 that is out of order, the output unit 123 cannot identify the device 171 (for example, "The device inquired could not be specified. To the call center." Do you want to connect? ... ") is generated as output information. When connecting to the call center 180, information (for example, device ID) related to the device 171 narrowed down by the first narrowing section 121 may be transmitted to the terminal 181 of the call center 180.

Further, for example, when the device 171 can be specified in step S912, the output unit 123 generates output information such as the current response status and the situation occurring in the field. More specifically, the output unit 123 acquires the current status from the monitoring server 140, and uses the device ID of the specified device 171, the acquired current status, and the failure content 403 of the failure information 400 as output information. Generate. By using such output information, for example, the local worker 190 has already been dispatched, and the time until the local worker 190 arrives is notified to the inquirer 160, the user who uses the device 171 together with the inquirer 160, and the like. You will be able to feel relieved. Further, for example, by communicating the output information to the call center 180 and the local worker 190, it is possible to quickly perform work on the target device 171 at the site.

In step S917, the output unit 123 transmits the output information to at least one of the terminal 161 of the inquirer 160, the terminal 181 of the call center 180, the terminal 191 of the local worker 190, and the specified device 171 to perform the device identification process. finish.

In step S918, the interface unit 111 confirms with the inquirer 160 whether or not to connect to the call center 180. When the interface unit 111 determines that it is connected to the call center 180, it shifts the process to step S919, and when it determines that it is not connected to the call center 180, it ends the device identification process.

In step S919, the output unit 123 generates narrowing information (an example of output information). For example, the output unit 123 generates the device ID of the device 171 narrowed down by the second narrowing-down unit 122 and the failure content as the narrowing down information.

In step S920, the output unit 123 transmits the narrowing down information to the terminal 181 of the call center 180, and ends the device identification process. According to the narrowing down information, for example, the operator of the call center 180 can respond by voice in consideration of the narrowing down information, and it is not necessary to specify the device 171 from the beginning as in the conventional case, and the operator can respond more quickly. You will be able to do it.

FIG. 10 is a diagram showing an example of a screen displayed on the terminal 161 (display screen 1000).

Here, a case where both the elevator and the escalator existing at almost the same position are extracted from the position information of the inquirer 160 will be described as an example. In this case, it is possible to identify which is the case by additionally confirming the product type.

Therefore, on the display screen 1000, the question information of question 1001 "Is the device you are inquiring about an elevator or an escalator?" Is displayed. Then, the inquirer 160 inputs the answer 1002 "It is an elevator" to the question 1001, and the answer information of the answer 1002 is displayed on the display screen 1000.

Although not shown, if you can narrow down to multiple escalators, use questions such as "Are you going up or down?" Or "What floor is your destination?" Further narrowing down will be done.

According to this embodiment, the device to be inquired can be appropriately specified.

In addition, the present invention has, for example, the following characteristic configurations.

A device identification system (for example, device identification system 100) that identifies a device (for example, device 171) inquired from an inquirer (for example, inquirer 160), and is a terminal (for example) owned by the inquirer who inquires about the device. , Terminal 161) identifies information related to the location of the above equipment (for example, GPS location information, input current address, building name, bulletin board information in the car, station name around the site, surrounding building name, customer number, etc. The position information to be obtained) is acquired via the interface unit (for example, the interface unit 111), and a predetermined position is centered on a device (for example, a GPS position or a position specified by input from the inquirer 160) around the above position. Feature information (for example, characteristic information indicating the characteristics of the device to be managed stored in the first narrowing section (first narrowing section 121) for identifying the device 171) within the distance and the storage section (for example, the storage section 130). For example, the specification information 300, the failure information 400, the state information 500) and the feature information of the device specified by the first narrowing down unit (for example, the presence / absence of a failure, the feature information input by the inquirer) match. An output unit (for example, output) that outputs information (for example, output information) related to the second narrowing unit (for example, the second narrowing unit 122) for specifying the device and the device specified by the second narrowing unit. Part 123) and.

In the above configuration, the device to be inquired is specified from the position information that can be acquired from the terminal possessed by the inquirer and the feature information of the device used in the existing operation. Therefore, for example, a two-dimensional code unique to the device is provided. The device to be inquired can be specified without any need.

When the position of the device cannot be specified from the information acquired from the terminal by the first narrowing-down unit, the interface unit transmits question information indicating the answer question to which the position is associated to the terminal, and the terminal unit sends the question information. The answer information indicating the answer to the question is received (see, for example, step S906 and step S907), and the first narrowing-down unit sets the position associated with the answer of the answer information received by the interface unit. It is characterized in that it is specified as a position related to the above-mentioned device (see, for example, step S903).

According to the above configuration, for example, when GPS position information cannot be acquired, when there is no function for acquiring GPS position information, when transmission of GPS position information to the device identification system 100 is not permitted by the inquirer 160, etc. Even so, the position information of the position related to the device 171 can be acquired.

The interface unit transmits question information indicating a question requesting an answer to the characteristics of the device specified by the first narrowing unit to the terminal, and receives answer information indicating an answer to the question from the terminal (for example). , Step S914 and step S915.), The second narrowing-down unit is a feature information indicating a feature included in the answer of the answer information received by the interface unit, and a feature showing the feature of the device to be managed. It is characterized in that the device is compared with the information and the device whose feature information matches is specified (see step S912).

In the above configuration, for example, the devices that are roughly narrowed down by the position information are narrowed down by the feature information, so that the devices can be quickly narrowed down.

The second narrowing section refers to failure information (for example, failure information 400) indicating whether or not the device has failed when the inquirer makes an inquiry, and is specified by the first narrowing section. It is characterized in that a malfunctioning device is identified among the devices, and a device in which the feature information of the device to be managed and the feature information of the device identified as failing match is identified.

According to the above configuration, for example, narrowing down is performed in advance depending on the presence or absence of a failure, and then narrowing down is performed by the second narrowing down portion, so that the equipment can be quickly narrowed down.

The output unit is information related to a device that cannot be specified by the second narrowing section among the devices specified by the first narrowing section (for example, device ID, device failure content, current status, etc.). Is transmitted to a terminal provided in the call center.

According to the above configuration, for example, the operator of the call center can grasp the information related to the equipment narrowed down to the middle stage, so that the operator can quickly respond to the inquiry.

The output unit refers to the feature information (for example, state information 500) indicating the state of the device to be managed, and the information indicating the state of the device specified by the second narrowing-down unit (for example, the current state). The status) is generated, and the generated information is transmitted to the above terminal.

According to the above configuration, for example, the current status is transmitted to the inquirer's terminal, and the inquirer can confirm the current status, so that the inquirer's anxiety can be reduced.

The second narrowing-down unit refers to wide-area disaster information (for example, wide-area disaster information 600) indicating a wide-area disaster, determines whether or not a wide-area disaster has occurred, and the output unit uses the second narrowing-down unit. When it is determined by the department that a wide-area disaster has occurred, information indicating that a wide-area disaster has occurred is transmitted to the above terminal.
