Description

[Technical field]

[0001] The present invention relates to an installation work support system and an installation work support method for supporting the installation work of a product. [Background technology]

[0002] In a system for supporting on-site work, it is necessary to extract desired data from a huge amount of data by trial and error, and therefore the technology described in Patent Document 1 has been proposed. Patent Document 1 states that "the on-site work support system includes a design database in which design information related to construction or inspection is managed, a work information database that stores work items individually extracted from this design information, the criteria for each work item, and information on the order in which these work items are performed, a mobile terminal that downloads and displays on the screen a work procedure in which the work items are arranged based on the order information and inputs measured values ​​for each work item, a site information database that uploads the measured values ​​input by the mobile terminal in association with the date of implementation, and a report generation unit that generates a report in a specified format by associating at least the work items, the criteria for determination, the measured values, and the date of implementation." [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2015-18499 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the system described in Patent Document 1 only associates measurements taken on-site with the criteria, and does not consider the case where the measurements are outside the criteria. Therefore, when the measurements are outside the criteria, for example, a method of dealing with an error between the building and the drawing must be considered for each site, which requires a lot of time during on-site installation work.

[0005] In view of the above circumstances, there has been a demand for a method to improve the efficiency of on-site installation work. [Means for solving the problem]

[0006] In order to solve the above problems, an installation work support system according to one aspect of the present invention includes a worker terminal used by a worker who installs a product, a site information database in which design information of the site where the product installation work is performed is stored for each site, a work information database in which information on the product installation work is managed, and a control unit that receives information input to the worker terminal that can identify the product and the site and measurement value information on the product installation measured at the site, extracts the corresponding site design information from the site information database and the corresponding product installation work information from the work information database, calculates an installation work method for the site based on the extracted site design information and product installation work information, and presents information on the installation work method to the worker terminal. The site information database, the work information database, and the control unit are stored in the worker terminal 20. Effect of the Invention

[0007] According to at least one aspect of the present invention, information on an appropriate installation method for each site is presented to the worker terminal using information input to the worker terminal that can identify the product and the site, and measurement value information related to the installation of the product measured at the site, thereby improving the efficiency of the installation work at the site. Furthermore, even if the worker terminal is in an offline environment where it cannot receive radio waves, the worker terminal can obtain information necessary for supporting the installation work and present information on the installation work method. Problems, configurations and effects other than those described above will become apparent from the following description of the embodiments. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an example of a mode for carrying out the present invention (hereinafter referred to as an "embodiment") will be described with reference to the attached drawings. In this specification and the attached drawings, identical or similar components are given the same reference numerals, and duplicate explanations may be omitted, or only differences may be described. Furthermore, when there are multiple identical or similar components, they may be described with different subscripts added to the same reference numerals. Note that when it is not necessary to distinguish between these multiple components, the subscripts may be omitted in the description. The number of each component may be singular or plural, unless otherwise specified.

[0010] An installation work support system according to one embodiment of the present invention will be described. In this embodiment, the work content will be described by taking the work content related to the installation work of an elevator as an example. Generally, in the installation work of an elevator, since the car rises and falls vertically, there are strict restrictions on the error between the building (site) and the drawing, and it takes time to consider whether the product will fit into the building at each site.

[0011] However, the present invention is not limited to work related to elevator installation work, but can be applied to work at various sites, such as construction and installation. In addition, in this specification, the term "product" is not limited to final deliverables such as elevators, but may also include the main product of the final deliverable (e.g., a car, etc.), products other than the main product that are provided in association with the final deliverable, and parts that constitute or are related to each product. In this specification, the terms "installation" and "mounting" have the same meaning in that they are the work of installing a product at a site, but if one were to make a distinction, "installation" is the concept of installing a relatively large product, and "mounting" is the concept of installing a relatively small product.

[0012] [Overall configuration of the installation work support system and internal configuration of the management server] The overall configuration of an installation work support system and the internal configuration of a management server according to an embodiment of the present invention will be described with reference to FIG.

[0013] Fig. 1 is a block diagram showing an example of the overall configuration of an installation work support system according to one embodiment of the present invention and an example of the internal configuration of a management server. As shown in Fig. 1, an installation work support system 1 according to one embodiment includes a management server 10 and worker terminals 20A to 20C that are connected to each other via a communication network N. The installation work support system 1 supports installation work at the site by using installation work auxiliary tools (for example, see Figs. 7 to 12 described later).

[0014] (Management Server) 1 is an information processing device managed by, for example, a customer department that manages customer information for an elevator installation site, and a work management department that manages design information and work methods. The management server 10 includes a site information DB (Data Base) 30, a work information DB 40, a control unit 50, and a communication unit 55. In this way, the management server 10 has the site information DB 30 and the work information DB 40 as databases for the work management department.

[0015] -Site information DB- The site information DB30 is a database that mainly manages design information (site information) related to work sites, and stores and manages site information for each site where a product is to be installed. FIG. 1 shows an example in which site information 31A to 31C for installation sites A, B, and C are stored in the site information DB30. In the following explanation, the target site is site A, and the control unit 50 accesses the site information 31A for site A. Similarly, the worker terminal 20A is used by a site worker at site A. Site information 31B for site B and site information 31C for site C are similar to site information 31A for site A, and therefore explanations thereof will be omitted.

[0016] In this specification, when there is no need to distinguish between the site information 31A to 31C of the sites A to C, they will be referred to as "site information 31." Also, when there is no need to distinguish between the worker terminals A to C used by the field workers at the sites A to C, they will be referred to as "worker terminal 20."

[0017] As shown in FIG. 1, site information 31A for site A includes construction specification information 32, site design information 33, and product arrangement information .

[0018] The construction specification information 32 is information on the specifications of the construction (installation work) of the product to be installed. In this embodiment, the construction specifications for site A are the specifications for elevator construction. For example, in the case of elevator installation work, the construction specifications include information on optional equipment. For example, in the case of an elevator, information on optional equipment includes the presence or absence of an air conditioner, the capacity, the opening size, and the type of jamb.

[0019] The site design information 33 is design information about the relationship between the installation site and the product. In this embodiment, it is information indicating the design dimensions of the elevator (e.g., car, jamb, etc.) to be installed at the site A, and the dimensions between the building structure and the elevator at the design stage.

[0020] The product arrangement information 34 is information on the arranged product and related parts. In this embodiment, it is information on the model (type) of the elevator to be installed at the site A and the parts to be provided in association with the elevator. For example, the information on the parts includes the type, quantity, size, etc. of the parts.

[0021] -Work information DB- As shown in FIG. 1, the work information DB 40 is a database for managing information related to work at a work site, and stores work procedure information 41, installation reference value information 42, and work caution information 43.

[0022] The work procedure information 41 is information showing the work flow (work procedure) and the work method, and in this embodiment, it is associated with the construction specifications of each elevator. For example, the work procedure information 41 is a database that contains information on the method of on-site processing of parts according to the error of the building structure and the countermeasure method. The work procedure information can be said to be the work manual of the target product.

[0023] The installation reference value information 42 is information on the installation reference values ​​of products and parts, and is a database having information on the installation reference values ​​of products and each part that differ for each construction specification. The installation reference value information may be only an upper limit or a lower limit, or a range determined by an upper limit and a lower limit. For example, the installation reference value information is information such as, when a product is installed in an interior wall of a building (hoistway), the distance from the interior wall of the building to the car must be at least a certain number of centimeters, or the distance between a reference position described below and the product must be within a certain range of centimeters.

[0024] The work caution information 43 is information on precautions to prevent quality deterioration and rework, and is a database that contains precautions according to each specification and building structure. For example, since the precautions for work may differ depending on the dimensional error of the building, it may be possible to extract work caution information according to each dimensional error.

[0025] -Control Unit- The control unit 50 executes necessary calculation processing to support the work of on-site workers in the installation work, and transmits information on the installation work method based on the calculation results to the worker terminal 20. As shown in FIG. 1, the control unit 50 includes a design information extraction unit 51, a criterion extraction unit 52, a calculation processing unit 53, and an installation work method extraction unit 54.

[0026] The design information extraction unit 51 receives an extraction request from the worker terminal 20, extracts design information that is the extraction condition specified in the extraction request from the site information DB 30, and returns the extracted design information to the request source as response information.

[0027] The judgment criteria extraction unit 52 receives an extraction request from the worker terminal 20, extracts judgment criteria that match the extraction conditions specified in the extraction request from the work information DB 40, and returns the extracted judgment criteria to the request source as response information. The judgment criteria are reference values ​​for determining whether the position of a product (e.g., an elevator car) to be installed in a building or the like is appropriate according to the design. The installation reference value information 42 in the work information DB 40 can be used as the judgment criterion. However, depending on the conditions at the site where the installation work is performed, the installation reference value may not be used as the judgment criterion as is. In such cases, the judgment criterion is calculated from the installation reference value and the information on the on-site measurement value. For example, if the installation reference value is 10±5 mm (5 to 15 mm), the judgment criterion is set to 11 to 13 mm, taking into account the conditions at the site.

[0028] The calculation processing unit 53 receives a calculation request from the worker terminal 20 and executes calculations according to a predetermined algorithm using information (e.g., on-site measurement values) transmitted together with the calculation request. In the calculation processing unit 53, algorithms required for each installation work, such as product fit consideration, are constructed. As an example, the calculation processing unit 53 calculates the installation dimensions of the product at the site. The installation dimensions of the product are within the product installation reference values ​​and are installation dimensions recommended at the site. Depending on the structure of the site, there may be installation dimensions (installation positions) at which the product cannot be installed even if they are within the product installation reference values. Therefore, it is necessary to calculate the installation dimensions of the product according to the structure of the site.

[0029] The installation work method extraction unit 54 receives an extraction request from the worker terminal 20, extracts the installation work method, which is the extraction condition specified in the extraction request, from the calculation results of the calculation processing unit 53 and the work information DB 40, and returns the extracted installation work method to the request source as response information. For example, information on the installation work method includes information such as the mounting dimensions of the product, work procedures, and work content of each work procedure. Note that the installation work method extraction unit 54 may also function as the calculation processing unit 53.

[0030] In addition to the above-mentioned functional units, the control unit 50 can receive, process, and respond to various requests from the worker terminal 20, but illustration and detailed description are omitted. As an example, the control unit 50 has a functional unit that receives an acquisition request from the worker terminal 20, searches for information stored in the site information DB 30 and the work information DB 40, and returns the search results to the request source as response information. This allows the worker terminal 20 to search for and acquire the necessary information via the management server 10, and display it.

[0031] When the communication unit 55 receives a request (e.g., a request to obtain information) from the worker terminal 20 via the communication network N, it passes the request to the control unit 50. Furthermore, when the communication unit 55 receives response information (e.g., screen information) from the control unit 50, it returns the response information to the worker terminal 20 that sent the request via the communication network N. However, in the following description of the processing of each functional unit of the control unit 50, the processing of the communication unit 55 will be omitted, and each functional unit will be described as transmitting and receiving various information and data to and from the worker terminal 20.

[0032] The worker terminal 20 is an example of an information processing terminal operated by a worker at a site where an elevator or the like is being installed. As the worker terminal 20, a mobile terminal such as a mobile phone, a smartphone, a tablet type mobile terminal, or a laptop type personal computer is used. On-site workers can easily operate the worker terminal 20 at the site. The on-site workers then perform various operations, such as inputting the serial number of a product (e.g., an elevator) and inputting on-site measurement values ​​for the day, through application software installed on the worker terminal 20.

[0033] In this embodiment, the worker terminal 20 is characterized by having terminal data 60 that stores information equivalent to the information managed by the management server 10. The terminal data 60 stores information for supporting the work of on-site workers at a specific site. The worker terminal 20 is capable of displaying information required for installation work on the display unit 21 even in an environment in which communication with the management server 10 is not possible.

[0034] (Worker terminal) Here, the internal configuration of the worker terminal 20 will be described with reference to FIG. 2 is a block diagram showing an example of the internal configuration of worker terminal 20A. Since worker terminals 20A to 20C have the same basic configuration except for the information stored therein, worker terminal 20A used by a field worker at site A will be described as a representative example.

[0035] 2, the worker terminal 20A includes a display unit 21 that displays various information, an input unit 22 that receives information input by a field worker, a control unit 23, a communication unit 27, and terminal data 60. The worker terminal 20A has the same functions as a general mobile terminal. For example, the worker terminal 20A has a calling function and a function of displaying information acquired from the management server 10 via the communication network N on the display unit 21.

[0036] The control unit 23 has a function of comprehensively controlling the worker terminal 20. The control unit 23 also has a site information input processing unit 24, a site measurement value input processing unit 25, and an installation work method display processing unit 26. Each functional block indicates a function of an installation work support tool (application software) not shown.

[0037] The site information input processing unit 24 allows the site worker to input information (e.g., a product serial number) that can identify the installation work to be performed at the target site as site information via the input unit 22. In this embodiment, the serial number is linked to information such as the site name and the product name and model (see Figs. 7 and 8 described later).

[0038] The on-site measurement value input processing unit 25 allows a site worker to input, as on-site measurement values, measurement values ​​(actual measurements) of various dimensions related to the installation of the product at the target site via the input unit 22. The on-site measurement values ​​indicate, for example, actual measurements of the interior of a building to which the elevator will be delivered, and / or actual measurements from a reference position (described below) to an interior wall of the building according to the position of the product (e.g., a car). The dimension from the reference position to an object such as the interior wall of the building represents the relative position from the current product to the on-site object.

[0039] The control unit 23 transmits an extraction request to the management server 10 using the input serial number and on-site measurement values ​​as extraction conditions, and ultimately receives the extracted installation work method from the management server 10. The transmission of the extraction request and the reception of the installation work method may be performed by any of the site information input processing unit 24, the site measurement value input processing unit 25, and the installation work method display processing unit 26. Alternatively, the transmission of the extraction request may be performed by the site information input processing unit 24 or the site measurement value input processing unit 25, and the reception of the installation work method may be performed by the installation work method display processing unit 26. Alternatively, the control unit 23 may include an extraction request unit (not shown), and the extraction request unit may transmit the extraction request and receive the installation work method.

[0040] The installation work method display processing unit 26 displays the extracted installation work method on the display unit 21 of the worker terminal 20A.

[0041] Furthermore, the worker terminal 20A can receive the results of the calculation process and the data of the judgment criteria from the management server 10. For example, the control unit 23 of the worker terminal 20A can display on the display unit 21 the calculation results such as the difference between the site design information 33 and the site measurement values ​​(actual measurement values) and information on whether the calculation results satisfy the judgment criteria.

[0042] When the communication unit 27 receives request information (e.g., a request to extract information) from the control unit 23, it transmits the request information together with the provision information to the management server 10, which is the destination of the request, via the communication network N. In addition, when the communication unit 27 receives response information (e.g., an installation work method) from the management server 10 via the communication network N, it passes the response information to the control unit 23.

[0043] The data in terminal 60 includes information (data) equivalent to the information in the site information DB 30, the work information DB 40, and the control unit 50 managed by the management server 10. Fig. 2 shows that the data in terminal 60 includes a specific site information DB 70, a specific work information DB 80, and the control unit 50. Before work at a specific site begins (for example, at night), a process is performed to import site information, etc. into the data in terminal 60 of the worker terminal 20. Then, the field worker enters the site with the necessary information (and functions) downloaded to the worker terminal 20.

[0044] The specific site information DB70 is a database that manages specific site information among the current status information stored in the site information DB30 of the management server 10. The specific site information DB70 of the worker terminal 20A stores site information 31A of site A. As shown in Fig. 1, the site information 31A of site A includes construction specification information 32, site design information 33, and product arrangement information 34.

[0045] The specific work information DB 80 is a database that manages specific work information among the work information stored in the work information DB 40 of the management server 10. The specific work information DB 80 of the worker terminal 20A stores work information of site A. The work information DB 80 of site A includes construction specification information 82, site design information 83, and product arrangement information 84. Usually, information about work at a work site is often the same regardless of the site if the product is the same. Therefore, when the management server 10 manages a work information DB 40 common to all sites, the specific work information DB 80 in the worker terminals 20A to 20C is the same as the work information DB 40. However, when using an installation work support tool, it is desirable to confirm at the work site that the specific work information DB 80 and the work information DB 40 in the management server 10 are consistent.

[0046] The control unit 50 of the data in terminal 60 has the same functions as the control unit 50 in the management server 10. That is, the control unit 50 of the data in terminal 60 executes necessary calculation processing to support the work of the on-site worker in the installation work, and outputs information on the installation work method to the display unit 21 based on the calculation result. As shown in FIG. 1, the control unit 50 includes a design information extraction unit 51, a judgment criterion extraction unit 52, a calculation processing unit 53, and an installation work method extraction unit 54. By importing the processing that has been performed on the communication network N via the management server 10 into the control unit 50 (application) in the worker terminal 20, it is possible to realize high-speed processing and offline operation.

[0047] Although it has been explained that this control unit 50 is the same as the control unit 50 in the management server 10, some functions of the control unit 50 in the management server 10 may be changed. Specifically, this corresponds to a case where the version of the control unit 50, which is an application, is updated. This may result in, for example, a change in the extraction rule of the judgment criteria in the judgment criteria extraction unit 52. Therefore, when using the installation work support tool, it is desirable to confirm at the work site that the control unit 50 of the worker terminal 20 and the control unit 50 in the management server 10 are consistent.

[0048] [Hardware configuration of each device in the installation support system] Here, the hardware configuration of the control system of each device constituting the installation work support system 1 will be described with reference to Fig. 3. Here, the hardware configuration of the control system of the management server 10 will be described.

[0049] Fig. 3 is a diagram showing an example of the hardware configuration of a control system of the management server 10. A calculator 300 shown in Fig. 3 is an example of hardware used as a computer. The management server 10 according to this embodiment realizes installation work support performed by the respective functional blocks shown in Fig. 1 in cooperation with each other by the calculator 300 (computer) executing a program.

[0050] The computer 300 includes a central processing unit (CPU) 301, a read only memory (ROM) 302, and a random access memory (RAM) 303, all of which are connected to a system bus. The computer 300 further includes a non-volatile storage 304 and a communication interface 305.

[0051] The CPU 301 reads out program code of software for realizing each function according to this embodiment from the ROM 302, loads it into the RAM 303, and executes it. Variables, parameters, etc. generated during the arithmetic processing of the CPU 301 are temporarily written into the RAM 303, and these variables, parameters, etc. are read out as appropriate by the CPU 301. The function of the control unit 50 of the management server 10 is realized by the CPU 301 executing the program code read out from the ROM 302. However, other processors such as an MPU (Micro Processing Unit) may be used instead of the CPU 301.

[0052] The non-volatile storage 304 is an example of a recording medium, and is capable of storing data used by a program, data obtained by executing a program, and the like. The site information DB 30 and the work information DB 40 of the management server 10 described above are configured using the non-volatile storage 304. An operating system (OS) and programs executed by the CPU 301 may also be recorded in the non-volatile storage 304. As the non-volatile storage 304, a hard disk drive (HDD), a solid state drive (SSD), a disk medium using light or magnetism, a semiconductor memory card, or the like is used.

[0053] A communication device such as a network interface card (NIC) is used for the communication interface 305. The communication interface 305 is configured to be capable of transmitting and receiving various data to and from an external device via a communication network such as a LAN or the Internet to which a terminal is connected, or a dedicated line, etc. The function of the communication unit 55 of the management server 10 described above is realized by using the communication interface 305.

[0054] Similarly, the hardware of the control system of the worker terminal 20 can use the configuration of the computer 300. The terminal internal data 60 is configured using the non-volatile storage 304. The functions of the control unit 23 and the control unit 50 of the worker terminal 20 are realized by the CPU 301 executing the program code read from the ROM 302 or the non-volatile storage 304. The worker terminal 20 may have two processors instead of one processor (CPU 301). One processor realizes the functions of the control unit 23, and the other processor realizes the functions of the control unit 50. The communication unit 27 is configured by a communication interface 305.

[0055] A display device and an input device (not shown) are connected to the calculator 300 of the worker terminal 20. The display device is a monitor such as a liquid crystal display, and displays a GUI screen and the results of arithmetic processing performed by the CPU 301. The input device generates an input signal according to a user's operation and outputs it to the CPU 301. The input device may be, for example, a mouse, a keyboard, or a touch sensor, and the user can operate the input device to input information and instructions. The display device and the input device may be integrated into a touch panel. The display unit 21 of the worker terminal 20 can be configured using such a display device. Also, the input unit 22 of the worker terminal 20 can be configured using such an input device. Note that the display device and the input device may be connected to the computer 300 of the management server 10.

[0056] [Installation work support system processing] Next, the process (installation work support method) performed by the management server 10 and the worker terminal 20 of the installation work support system 1 will be described with reference to FIGS.

[0057] (Processing using information and control unit in the management server) 4 is a sequence diagram showing an example of processing by the management server 10 and the worker terminal 20. The processing shown in FIG. 4 is an example of processing using information in the management server 10 (site information DB 30, work information DB 40) and the control unit 50.

[0058] It is assumed that application software (installation work support tool) installed in the worker terminal 20 is running. First, in a field information input process, the field information input processing unit 24 of the worker terminal 20 displays a screen that prompts the field worker to input the serial number of the target product via the input unit 22 of the worker terminal 20 (S1).

[0059] Then, the serial number input by the field worker is transmitted by the control unit 23 from the worker terminal 20 to the management server 10 via the communication network N (S2). As will be described later with reference to Fig. 7, the field worker specifies the work item (work name) to be performed. Therefore, in step S2, it can be considered that the work item (work name) is also transmitted to the management server 10 in addition to the serial number.

[0060] Next, in the design information extraction process, the design information extraction unit 51 of the management server 10 refers to the site information DB 30, which is one of the databases, and extracts the construction specification information 32, site design information 33, and product arrangement information 34 corresponding to the inputted manufacturing number (S3).

[0061] Next, in a criterion extraction step, the criterion extraction unit 52 of the management server 10 refers to the work information DB 40, which is one of the databases, and extracts the mounting reference value information 42 as the criterion corresponding to the input serial number (S4).

[0062] Then, the construction specifications, design dimensions, and judgment criteria extracted in the design information extraction process of step S3 and the judgment criterion extraction process of step S4 are transmitted by the control unit 50 from the management server 10 to the worker terminal 20 via the communication network N (S5).

[0063] Next, in a field measurement value input step, the field measurement value input processing unit 25 of the worker terminal 20 inputs the field measurement value to the field measurement value input processing unit 25 of the worker terminal 20 via the input unit 22 of the worker terminal 20 (S6).

[0064] Then, the input results of the on-site measurement values ​​are transmitted by the control unit 23 from the worker terminal 20 to the management server 10 via the communication network N (S7).

[0065] Next, in the calculation processing step, the calculation processing unit 53 of the management server 10 calculates the installation dimensions, etc. of the target product using the construction specification information 32, site design information 33, product arrangement information 34, and installation reference value information 42 extracted in steps S3 and S4, and the on-site measurement values ​​input in step S6 (S8).

[0066] Next, in an installation work method extraction step, the installation work method extraction unit 54 of the management server 10 extracts an installation work method of the target product from the work information DB 40 (work procedure information 41, installation reference value information 42, and installation work caution information 43) in association with the calculation result in step S8 (S9). In this embodiment, the information on the installation work method includes the installation dimensions of the target product, the work procedures, and the work contents of each work procedure. The information on the installation work method may also include work procedure caution information.

[0067] The information on the installation work method includes at least one of the following: the installation dimensions of the product at the site, the work procedure, and the work content of each work procedure. For example, the installation dimensions of the product are basically included in the information on the installation work method, but there may be cases where accurate installation dimensions are not required depending on the product, and installation reference values ​​are not necessary.

[0068] Then, the extracted installation work method (work procedure information 41, installation reference value information 42, and work caution information 43 during installation work) is transmitted by the control unit 50 from the management server 10 to the worker terminal 20 via the communication network N (S10).

[0069] In an installation work method display step, the installation work method display processing unit 26 of the worker terminal 20 displays the installation work method transmitted from the management server 10 on the display unit 21 of the worker terminal 20 (S11).

[0070] By inputting site information (serial number) and site measurement values ​​to the worker terminal 20 through such installation work support processing, the management server 10 automatically calculates the installation work method (for example, product fit consideration and dimensions required for installation) based on this information. Then, by presenting the installation work method appropriate for each site thus calculated to the worker terminal, it is possible to streamline the consideration and calculation work that was previously carried out for each site.

[0071] (Processing using information captured on the worker's terminal and the control unit) Fig. 5 is a sequence diagram showing an example of processing by the management server 10, the worker terminal 20, and the in-terminal data 60. The processing shown in Fig. 5 is an example of processing using information (specific site information DB 70, specific work information DB 80) imported from the management server 10 into the worker terminal 20 and the control unit 50. As shown in Fig. 2, the in-terminal data 60 is provided in the worker terminal 20, but the worker terminal 20 and the in-terminal data 60 are shown separately to show that the control unit 23 and the control unit 50 in the in-terminal data 60 operate in cooperation with each other.

[0072] First, the field worker starts up the application software (installation work support tool) installed in the worker terminal 20. The control unit 23 of the worker terminal 20 executes a process of connecting to the management server 10 via the communication network N (S21). When the control unit 23 of the worker terminal 20 establishes a connection between the worker terminal 20 and the management server 10, the control unit 23 checks with the management server 10 via the communication network N whether various information in the intra-terminal data 60 of the worker terminal 20 is the latest. The various information in the intra-terminal data 60 is, for example, the specific site information DB 70 and information in the control unit 50. It may also include a specific work information DB 80.

[0073] Upon receiving a confirmation request from the worker terminal 20, the control unit 50 of the management server 10 transmits information representing the status of various information (site information DB 30, work information DB 40, control unit 50) managed by the management server 10 to the worker terminal 20 (S22). The information representing the state of each piece of information is information representing the age (newness) of each piece of information. For example, the information representing the state of each piece of information may be the last update date or version of each piece of information.

[0074] Next, the control unit 23 of the worker terminal 20 receives the information representing the state of the various information in the management server 10, and compares the information representing the state of the various information in the intra-terminal data 60 with the information representing the state of the various information in the management server 10. Then, based on the comparison result, the control unit 23 requests the management server 10 to transmit the differences between the various information in the intra-terminal data 60 and the various information in the management server 10 (S23). In this way, when the worker terminal 20 connects to the management server 10, the application software of the worker terminal 20 checks various information in the management server 10 to see whether the various information in the terminal data 60 is up to date.

[0075] Next, the control unit 50 of the management server 10 receives a request to transmit the differences in various information from the worker terminal 20, and extracts information corresponding to the specific site information DB 70 from the site information DB 30 (S24).

[0076] Furthermore, when the information in the control unit 50 is the target of the difference transmission request, the control unit 50 of the management server 10 extracts (S25) the information in the control unit 50. The information in the control unit 50 is information (programs, data, parameters, etc.) related to application software.

[0077] When the worker terminal 20 and the management server 10 are connected for the second or subsequent time, various information has already been stored in the terminal data 60 of the worker terminal 20. Therefore, when the worker terminal 20 is connected for the second or subsequent time, the control unit 50 of the management server 10 extracts only the difference between the site information of the specific site stored in the site information DB 30 and the information in the specific site information DB 70 of the terminal data 60. For example, in the case of site A, the difference between the site information 31A (FIG. 1) of site A in the site information DB 30 and the site information 31A (FIG. 2) of site A in the specific site information DB 70 is extracted. The same applies to the information in the control unit 50. Note that when there is a difference between the specific work information DB 80 of the terminal data 60 and the work information DB 40 of the management server 10, it becomes the subject of information extraction.

[0078] Next, the control unit 50 of the management server 10 transmits the extracted various information to the worker terminal 20. The control unit 23 of the worker terminal 20 imports the various information transmitted from the management server 10 into the terminal data 60, and updates the various information in the terminal data 60 (S26). At this time, the control unit 23 of the worker terminal 20 may display on the display unit 21 that various information within the terminal data 60 is being updated (S27).

[0079] Fig. 6 shows an example of a display indicating that various information in the terminal data 60 is being updated. Fig. 6 shows an example of a display screen W0 on which the installation work support tool displays the message "Information being updated...". A bar-shaped progress bar indicating the progress of the process or work is displayed on the display screen W0. This allows the field worker to recognize that the information related to the installation work support tool is being updated on the worker terminal 20, and that the information related to the installation work support tool will be the latest information after the update.

[0080] When the updating of various information in the intra-terminal data 60 is completed, the control unit 23 of the worker terminal 20 and the control unit 50 in the intra-terminal data 60 execute the processes of steps S28 to S38. The processes of steps S28 to S38 are the same as the processes of steps S1 to S11 in FIG. However, the processing of steps S30 to S32 and S35 to S37 is mainly performed by the control unit 50 in the terminal data 60 of the worker terminal 20, not by the control unit 50 in the management server 11. The control unit 50 in the terminal data 60 uses a specific site information DB 70 and a specific work information DB 80, not the site information DB 30 and work information DB 40 (FIG. 1) of the management server 10.

[0081] As described above, the installation work assistance system 1 according to one embodiment has the following configuration. The installation work assistance system 1 includes a worker terminal 20 used by a worker who performs the installation work of a product, a site information database (specific site information DB70) in which design information of the site where the product installation work is performed is stored, and a work information database (specific work information DB80) in which information related to the product installation work is managed. The installation work assistance system 1 also includes a control unit (control unit 50) that receives information that can identify a product and a site and measurement value information related to the installation of a product measured at the site, which are input to the worker terminal 20, extracts the design information of the corresponding site from the site information database and information related to the installation work of the corresponding product from the work information database, calculates an installation work method for the site based on the extracted design information of the site and information related to the installation work of the product, and presents information on the installation work method to the worker terminal 20. In order to accommodate an offline environment, the site information database, the work information database, and the control unit are stored in the worker's terminal.

[0082] According to the present embodiment having the above configuration, the control unit 50 of the worker terminal 20 uses information input to the worker terminal 20 that can identify the product and the work site, and measurement value information related to the installation of the product measured at the work site, to present information on an appropriate installation work method for each work site to the worker terminal 20. This can improve the work efficiency of the installation work at the work site. Therefore, a highly convenient installation work support technology is provided at each work site. Furthermore, even in an offline environment where the worker terminal 20 cannot receive radio waves, the worker terminal 20 has information necessary for supporting the installation work, and can present information on the installation work method on the display unit 21. Therefore, the on-site worker can use the installation work support tool even in an offline environment. Furthermore, by operating the installation work support tool of the worker terminal 20 in an offline environment, the exchange of various information and calculations between the control unit 23 and the control unit 50 can be processed at high speed.

[0083] In the above-described embodiment, the site information database (specific site information DB70) and work information database (specific work information DB80) of the worker terminal 20 only need to have at least a portion of the information in the site information database (site information DB30) and work information database (work information DB40) of the management server 10.

[0084] In this embodiment configured as above, only the information necessary for the work to be performed at the site can be acquired from the management server 10 and stored in the worker terminal 20. Therefore, the resources and data processing amount of the worker terminal 20 can be reduced.

[0085] In the above-described embodiment, the worker terminal 20 includes an overall control unit (control unit 23) that performs overall control of the worker terminal 20. The overall control unit retrieves at least from the management server 10 the difference between the site information database (specific site information DB70) of the worker terminal 20 and the corresponding site information database (site information DB30) stored in the management server 10, and the difference between the control unit 50 of the worker terminal 20 and the control unit 50 stored in the management server 10, and updates the site information database and control unit 50 of the worker terminal 20 to the latest states.

[0086] In this embodiment configured as above, at least a part of the information and functions managed by management server 10 is downloaded to worker terminal 20, and at least a part of the information and functions managed by management server 10 is held in worker terminal 20. As a result, even if worker terminal 20 is in an offline environment where it cannot receive radio waves, worker terminal 20 can obtain information necessary for supporting the installation work and present information on the installation work method on display unit 21. Furthermore, by updating the information and functions held in the worker terminal 20 to the latest state, the on-site worker can accurately carry out the work using the installation work support tool.

[0087] In this embodiment, the worker terminal 20 uses the information and functions managed by the management server 10, so that the on-site worker can of course use the installation work support tool in an online environment.

[0088] [First example of user interface] Next, a first example of a user interface will be described in the worker terminal 20 of the installation work support system 1. In the first example, a display example of a screen related to site information and an input example will be described with reference to Figs. 7 and 8.

[0089] Fig. 7 is a diagram showing a display example of a site information input screen on the worker terminal 20. The site information input screen W1 shown in Fig. 7 is a user interface equipped with a function for a field worker to input information for identifying a product (for example, a serial number). The field worker starts an installation work support tool (application software) (not shown) installed in the worker terminal 20, and causes the display unit 21 to display the site information input screen W1 (titled "Automatic Calculation Tool").

[0090] Here, the site information input screen W1 in Fig. 7 is determined for what construction work. A menu screen (not shown) displays the contents for selecting the work item (work name) and the like, and an input screen corresponding to the work item selected by the site worker is displayed on the worker terminal 20.

[0091] In the example of Fig. 7, the site information input screen W1 has the following input or display fields: (1) serial number, (2) site name, (3) product name and model, (4) model code, (5) specifications, (6) rails, (7) options, (8) earthquake resistance, (9) travel, (10) frame specifications, (11) hoist position, and (12) counterweight position. (5) Specifications are the specifications for the construction of the elevator, etc., and this information allows the user to understand what optional equipment is available for the elevator. Note that the items in the input or display fields are not limited to the above example.

[0092] Then, the site worker operates the input unit 22 to input (1) the serial number on the site information input screen W1 and presses the enter key. Here, the serial number is input as "XXXXXX-XX." When the site information input processing unit 24 (FIG. 2) of the control unit 23 accepts the input of the serial number, it transmits the serial number to the management server 10. In an offline environment, the information is transmitted to the data 60 in the terminal.

[0093] Fig. 8 is a diagram showing an example of site information displayed on a site information input screen W1 in the worker terminal 20. As shown in Fig. 8, site information (e.g., construction specification information 32, site design information 33, and product arrangement information 34) received from the management server 10 (terminal data 60 in an offline environment) based on the serial number input by the field worker is displayed in various corresponding fields on the site information input screen W1. In other words, (1) the serial number is associated with each of the items (2) to (12).

[0094] Here, construction specification information 32 includes (2) the site name "Test Building," (3) product name and model number "AAA-6-C045," (4) model code "CC-CC," and (5) specification "Standard." In addition, as on-site design information 33, (7) OP "800", (9) stroke "60m or more", (11) hoist position "left", and (12) counterweight position "rear left" are displayed. Furthermore, (6) rail "DDDD▼", (8) earthquake resistance "earthquake resistance class F", and (10) three-sided frame specification "large frame▼" are displayed as product arrangement information 34. The "▼" display indicates that the display is in a drop-down list format.

[0095] It should be noted that which items of information are received from the management server 10 (inside terminal data 60 in an offline environment) or input as the site situation can be freely set as the items to be input. As for various input methods, for example, a drop-down list may be provided in each field and items may be selected from the drop-down list and entered, or items may be freely entered. Furthermore, since the contents to be input or displayed differ depending on the elevator serial number or model name (type), the candidates in the drop-down list can be changed depending on the model.

[0096] Next, a display example of an input screen relating to on-site measurement values ​​and an example of calculation results in the worker terminal 20 of the installation work support system 1 will be described with reference to FIG. 9 and FIG.

[0097] FIG. 9 is a diagram showing an example of a display of an input screen for on-site measurement values ​​on the operator terminal 20. As shown in FIG. Fig. 10 is a diagram showing an example of a calculation result (installation standard) by inputting on-site measurement values ​​in the worker terminal 20. Fig. 9 and Fig. 10 show an example of input of on-site measurement values ​​in the worker terminal 20 of the installation work support system 1, and a display example of an installation work method extracted from the input result.

[0098] The on-site measurement value input screen W2 shown in Fig. 9 is a user interface equipped with a function for on-site workers to input measurement values ​​at the work site. The on-site measurement value input screen W2 has a work site diagram display area 710 that displays a diagram of the work site, and a on-site measurement value input area 720 for inputting measurement values ​​at the work site. Fig. 9 shows an example in which a cross-sectional view of the top space of the elevator or the pit space, which is the space below, is displayed in the work site diagram display area 710.

[0099] The site worker measures the various dimensions indicated in the work site diagram display area 710 of the site measurement value input screen W2, and inputs the measurement results in the site measurement value input area 720. Here, the various dimensions A, B, C left dimension, and D right dimension of the top space of the elevator and the pit space where the elevator will be installed are input.

[0100] Each dimension A to D is an actual measurement of the distance between a reference position at the site and the inner wall of a building. The reference position is a reference position when a product is installed at the site. For example, in elevator reference centering work, it is the position of a piano wire hung at the site for installation work. For example, each dimension A to D is an actual measurement of the distance between the piano wire and four points on the inner wall of a building. However, the piano wire is not limited to one piece. Multiple piano wires may be used to set multiple reference positions. Furthermore, the measurement target of the dimension is not limited to the distance between the piano wire and the inner wall of a building. The reference position is not limited to the piano wire, and can also be set to a part of the site, such as an inner wall or floor of a building.

[0101] The method of inputting each dimension may be, for example, selecting from a drop-down list, or freely inputting the dimension. Since the input contents differ depending on the elevator serial number or model name, the candidates in the drop-down list may be changed depending on the model.

[0102] 10 is a user interface that displays the results of calculation processing by the control unit 50 of the management server 10 based on the serial number and on-site measurement values ​​entered by the on-site worker. In an offline environment, the control unit 50 in the terminal data 60 executes the calculation instead of the management server 10. The result confirmation screen W3 has a work site diagram display area 810, an attachment reference value display area 820 that displays the attachment reference value (effective judgment criterion), and a response method display area 830.

[0103] The diagram displayed in the work site diagram display area 810 may be the same as that displayed in the work site diagram display area 710 in Fig. 9, or may be a diagram created with a different expression. The countermeasure display area 830 is an area that displays, as an example of an installation work method, a countermeasure method when the on-site measurement value is not within the range of the installation reference value. In Fig. 10, an example is shown in which "move the reference position ● mm to the left when viewed from the hole" is displayed as a countermeasure method.

[0104] The result of the judgment (outside the standard or within the standard) of whether the on-site measurement value meets the judgment standard (installation standard value) may be displayed in the installation standard value display area 820. That is, the control unit 50 (the calculation processing unit 53 or the installation work method extraction unit 54) of the management server 10 transmits information on whether the on-site measurement value meets the judgment standard (installation standard value) to the worker terminal 20. In an offline environment, the control unit 50 in the terminal data 60 passes the information to the control unit 23.

[0105] If the current on-site measurement value is within the judgment criteria, the on-site worker may proceed with the installation work of the product with the current on-site measurement value. Conversely, if the current on-site measurement value is outside the judgment criteria, as shown in Fig. 10, the installation work method extraction unit 54 of the control unit 50 may calculate the amount of movement from the current position of the product so as to satisfy the installation reference value as an installation work method (countermeasure), and display it on the worker terminal 20.

[0106] The management server 10 performs calculation processing from the information inputted on the site information input screen W1 and the site measurement value input screen W2, and extracts the mounting reference value information 42 (FIG. 1) as a judgment criterion. On the result confirmation screen W3, the mounting reference value information 42 received from the management server 10 is displayed as a judgment criterion in the mounting reference value display area 820 of the result confirmation screen W3. The mounting reference value information 42 corresponds to the mounting reference value information 82 (FIG. 2) in an offline environment. The on-site worker checks the result confirmation screen W3 and performs the work in accordance with the elevator installation standards. In this manner, the installation work support system 1 can support the installation work in an appropriate manner for each installation work site.

[0107] As described above, in the installation work support system of this embodiment, when a control unit (for example, the control unit 50 in the management server 10 or in the terminal data 60) determines that the measurement value information of the product does not satisfy the product installation reference value contained in the information related to the installation work of the product, it calculates, as an installation work method, the amount of movement from the product's current position (the response method in the response method display area 830) so as to satisfy the installation reference value.

[0108] According to this embodiment, even if the on-site measurement information is not within the range of the product installation standard value, the amount of product movement required to meet the installation standard value is displayed on the worker's terminal, allowing the on-site worker to implement appropriate measures without delay.

[0109] Furthermore, in the installation work support system according to this embodiment, the screen (result confirmation screen W3) on the worker terminal that displays information on the installation work method includes an area for displaying a drawing of the site where the installation work will be performed (work site diagram display area 810), an area for displaying the product installation reference value (installation reference value display area 820), and an area for displaying the installation work method when it is determined that the product measurement value information does not satisfy the installation reference value (response method display area 830).

[0110] According to this embodiment, even if the on-site measurement information is not within the range of the product's installation standard values, the on-site worker can promptly confirm the installation work method (response method) to be used in the event that it is determined that the installation standard values ​​are not met.

[0111] [Second example of user interface] Next, a second example of a user interface in the worker terminal 20 of the installation work support system 1 will be described. In the second example, examples of work procedure information, installation reference value information linked to the contents thereof, and work caution information displayed on the worker terminal 20 of the installation work support system 1 will be described with reference to Fig. 11 and Fig. 12. Here, the work of installing a product in a hoistway or a car is assumed.

[0112] FIG. 11 is a diagram showing an example of a display of a table of contents of work procedure information on the worker terminal 20. As shown in FIG. 11, work procedure information received from the management server 10 (terminal internal data 60 in an offline environment) is displayed on the work procedure information display screen W4. Here, an example is shown in which the table of contents of the work procedure is displayed for the installation work of product A (title: [2] Product A installation), which is one of the work procedures of the installation work of elevator X. On the work procedure information display screen W4, items from "2.1 Product Overview" to "2.11 Work Procedure H" are displayed as the table of contents. "Product Overview" is information showing an overview of the target product (product A in this example). "Shipping Form" is information showing information on the form of packaging when shipping a product from a factory to a site, for example. "Procedure Overview" is information showing an overview of the entire plurality of work procedures shown below.

[0113] In the work procedure information display screen W4, a link is set for each displayed item, and when a site worker clicks on an icon with a link set, the screen transitions to a work procedure content display screen W5 (see FIG. 12 described later) where one or more pieces of work procedure information corresponding to that item are displayed. FIG. 11 shows an example in which "Link 1" to "Link 11" are set for the items in the table of contents from "2.1 Product Overview" to "2.11 Work Procedure H", respectively.

[0114] The order of the work procedures A to H on the work procedure information display screen W4 and / or the work content of each work procedure may change depending on the actual measured values ​​at the site. That is, in this embodiment, the work procedures and the work content of each work procedure are presented as an example of information on the installation work method suitable for the site according to the actual measured values ​​at the site. With this configuration, the site worker can carry out the installation work in accordance with the work procedure suitable for the site and the work content of each work procedure. The work content of each work procedure is displayed by the display screen shown in FIG. 12.

[0115] Fig. 12 is a diagram showing an example of the display of installation reference value information and work caution information linked to the contents of work procedure information on the worker terminal 20. Fig. 12 shows an example of a work procedure content display screen W5 when a link icon set for "2.10 Work Procedure G" is clicked among the items in the table of contents of the work procedure for the installation work of product A of elevator X. The work procedure content display screen W5 displays the specific work content of the selected work procedure G (adjustment of part a5), related installation reference value information, work caution information, etc.

[0116] The work procedure content display screen W5 displays an installation dimension adjustment diagram 1010 showing how to adjust the installation dimensions of part a5, a surface matching adjustment diagram 1020 showing how to adjust the surface matching of part a5, and a spring setting diagram 1030 showing how to set the spring that part a5 has.

[0117] The mounting dimension adjustment diagram 1010 displays mounting reference value information. This mounting dimension adjustment diagram 1010 is an area that displays a method for adjusting the mounting dimensions of a product when the mounting dimensions (position) of the product need to be adjusted (moved) as shown in FIG. 10. The surface matching adjustment diagram 1020 displays precautions for surface matching (an example of the work caution information 43, 83). In this way, the work procedure content display screen W5 displays, as the work content of the selected work procedure (adjustment of the target part), a method for adjusting the mounting dimensions of the part, a method for setting the springs of the part, and a method for setting the springs of the part.

[0118] In addition, a simple display of the work content of the selected work procedure and only the installation reference value information or work caution information linked to the work content may be displayed, and the details of the work procedure may be arranged as a separate link or as a link to a video. In Fig. 12, an example of a detailed procedure icon 1040 for confirming the details of the work content linked to the work procedure G selected by the on-site worker and a playback execution icon 1050 for instructing playback of a video explaining the work content linked to the work procedure G are shown. These data of the work procedure and the video are stored in the work procedure DB 40.

[0119] As described above, in the installation work support system according to this embodiment, the screen (work procedure information display screen W4) on the worker terminal that displays information on the installation work method displays a number of work procedures at the site (e.g., work procedures A to H) and icons (e.g., link 1 to link 11) that link to the work content for each of the multiple work procedures.

[0120] According to this embodiment, a plurality of work procedures are displayed based on the on-site information such as the serial number and the on-site measured values ​​input to the worker terminal, so that the on-site worker can check the procedures at any time. Also, by clicking an icon that links to the work content of the work procedure, the worker can select the work procedure and check the work content.

[0121] Furthermore, in the installation work support system according to this embodiment, a screen (work procedure content display screen W5) on a worker terminal that displays information on an installation work method includes an area for displaying the work content of a work procedure selected from a plurality of work procedures at the site (for example, an installation dimension adjustment diagram 1010, a surface alignment adjustment diagram 1020, and a spring set diagram 1030), and an area for displaying at least one of an icon for checking the details of the work content (detailed procedure icon 1040) and an icon for playing a video explaining the work content (playback execution icon 1050).
