(Example of extension function configuration by support tool)
Subsequently, with reference to FIG. 1, a configuration example of the extended function by the elevator examination support tool 300 will be described.

The storage unit 106 of the terminal device 100 stores a request case information database 306a, a geographic information database 306b, an environmental information database 306c, and a disaster prevention map database 306d.

The request case information database 306a stores request case information indicating a case of a request received from an elevator user in the past. The individual request case information is linked to the individual BIM parts that make up the elevator. For example, BIM parts for standard doors without rust prevention measures are linked to requests to improve rust on elevator doors in buildings within a predetermined distance from the sea. Further, for example, BIM parts of a car having a predetermined transportation volume and a request to eliminate congestion in the morning and evening of an elevator in a building having a predetermined floor area are linked. These requests are incorporated into the design standards established by the elevator manufacturer, and countermeasure parts that meet these requirements are prepared by the elevator manufacturer. Elevator maker design criteria include at least one of know-how, design procedures, items to be observed, prohibited items, etc. when designing an elevator.

The geographic information database 306b stores geographic information around the building to be designed. Specifically, the geographic information includes information that identifies the planned construction site of the building, such as the address and latitude / longitude of the planned construction site of the building. Geographic information may include information indicating altitude such as altitude and altitude of the planned construction site of the building, and information such as topography around the building represented by contour lines and the like.

The geographic information may be read from an external storage device (not shown), may be input via an input device 118, or may be acquired via a network 400. There may be. The above-mentioned geographic information is referred to when the operation of the integrated BIM model is analyzed by the control unit 102 described later.

The environmental information database 306c stores various environmental information that affects the environment of the building. For example, the environmental information is information that defines the environment inside and outside the building where the elevator is installed, and includes information such as various static environmental conditions and dynamic environmental conditions. In addition, the environmental information may include shape data and the like for constructing a three-dimensional model of an object that affects the environment inside and outside the building. Specifically, the environmental information includes, but is not limited to, at least one of information such as weather conditions, climatic conditions, sunshine conditions, wind speed conditions, humidity conditions, and salt damage conditions.

Human object information is information that defines a three-dimensional model that imitates a human who can move according to a predetermined condition. The predetermined condition can be, for example, at least one of the use and layout of the building. The human object information includes shape data for constructing a three-dimensional model imitating a human, as well as, for example, movement conditions including at least a starting point and a destination for each human object.

The environmental information may be read from an external storage device (not shown), may be input via the input device 118, or may be acquired via the network 400. There may be. In addition, the environmental information may include environmental simulation information derived from the above-mentioned geographic information and the like. The above-mentioned environmental information is referred to when the operation of the integrated BIM model is analyzed by the control unit 102 described later.

The disaster prevention map database 306d stores the information of the disaster prevention map of the area including the planned construction site of the building. Disaster prevention maps are generated based on, for example, various disaster prevention maps and hazard maps issued by government agencies. The disaster prevention map or the like issued by the administrative agency is acquired by, for example, the disaster prevention map acquisition unit 302b described later from the administrative agency server device 500 under the jurisdiction of the administrative agency.

The disaster prevention map stored in the disaster prevention map database 306d stores disaster information that may occur in each region in association with the location, based on the disaster information that has occurred in Japan. The type of disaster is not particularly limited, and various information such as typhoons, earthquakes, rains, and inundation are stored. Furthermore, the disaster prevention map also stores the frequency of disasters by region and location.

Further, the disaster prevention map of the first embodiment stores information indicating the importance of countermeasures for each disaster. This makes it possible to specify the priority to be taken for each disaster according to the importance of the disaster and the frequency of the disaster when multiple disasters may occur in the area.

The disaster prevention map stores not only disaster information associated with a position but also information on a disaster that may occur in consideration of the topography of the position. For example, the disaster prevention map contains information on whether or not it is close to the sea, such as whether or not it is within 1 km from the sea. Furthermore, the disaster prevention map holds information on whether or not inundation actually occurred, in addition to the proximity and altitude of the sea, for each position such as address or latitude / longitude.

The disaster information may include not only information on a disaster but also simulation results such as what kind of situation will occur when the disaster occurs.

Further, the disaster prevention map database 306d stores not only disaster information but also alert information associated with disaster information. As the alert information, for example, when it is within 1 km from the sea, it is stored that salt damage countermeasures are necessary.

Further, the disaster prevention map database 306d stores the alert information and the information on the recommended design in association with each other. For example, when the alert information is "within 1 km from the sea, salt damage countermeasures are required", information related to the design "rust countermeasures" is associated.

As another example, alert information indicating that "typhoons frequently come" is associated with information related to the design of "anti-vibration measures" as typhoon countermeasures.

Further, in the disaster prevention map database 306d, the information regarding the recommended design may be associated with the information for identifying the BIM part to be dealt with. For example, in the disaster prevention map database 306d, "rust countermeasures" are associated with information for identifying BIM parts indicating parts subject to rust countermeasures.

As another example, in the disaster prevention map database 306d, for example, "vibration-proof measures" are associated with information for identifying a plurality of BIM parts indicating a plurality of shaking detection sensors. From this, it can be understood that a plurality of vibration detection sensors should be installed as "anti-vibration measures".

The request case information database 306a, the geographic information database 306b, the environmental information database 306c, and the disaster prevention map database 306d as described above are referred to by the functional unit based on the extended function of the terminal device 100. However, the request case information database 306a, the geographic information database 306b, the environmental information database 306c, the disaster prevention map database 306d, and the like may be stored in the storage unit 206 of the server device 200 described above. When the functional unit based on the extended function of the terminal device 100 refers to these databases, it accesses the server device 200 from the terminal device 100, for example, via the network 400, and acquires various information from these databases.

The creation condition transmission unit 302x included in the control unit 102 of the terminal device 100 transmits the above-mentioned creation condition input by the user to the server device 200. The creation conditions may be those input by the user via the input device 118, or may be those read from an external storage device (not shown) in which the creation conditions are stored in advance.

The building information acquisition unit 302a acquires the BIM model of the building from the BIM model database of the storage unit 106. In addition, the building information acquisition unit 302a acquires geographic information from the geographic information database 306b. In addition, the building information acquisition unit 302a acquires environmental information from the environmental information database 306c.

The disaster prevention map acquisition unit 302b acquires a disaster prevention map from the disaster prevention map database 502 of the administrative agency server device 500. At this time, the disaster prevention map acquisition unit 302b accesses the administrative agency server device 500 of the administrative agency having jurisdiction over the area including the planned construction site of the building based on the geographical information acquired by the building information acquisition unit 302a, and the building. Obtain a disaster prevention map that includes the planned construction site of. The disaster prevention map acquisition unit 302b acquires the disaster prevention map from the administrative agency server device 500. For example, when the disaster prevention map database 502 of the administrative agency server device 500 is updated, the disaster alert extraction unit 302d described later extracts the disaster alert. It may be performed at the timing immediately before the event, or regularly or irregularly. The disaster prevention map acquisition unit 302b updates the disaster prevention map information of the disaster prevention map database 306d stored in the above-mentioned storage unit 106 based on the latest disaster prevention map from the acquired administrative agency server device 500.

The environmental alert extraction unit 302c extracts an environmental alert related to the elevator assumed from the environmental information based on the environmental information acquired by the building information acquisition unit 302a.

For example, if it is assumed from the weather conditions and weather conditions of the environmental information that the operation of the elevator may be hindered due to cold or intense heat, the environmental alert extraction unit 302c extracts the cold alert or intense heat alert as an environmental alert. To do. For example, if it is assumed that the operation of the elevator may be hindered by a strong wind from the wind speed condition of the environmental information, the environmental alert extraction unit 302c extracts the wind damage alert as an environmental alert. For example, if it is assumed that the elevator may be damaged by salt damage from the salt damage conditions of the environmental information, the environmental alert extraction unit 302c extracts the salt damage alert as an environmental alert.

When a plurality of these environmental alerts are extracted, the environmental alert extraction unit 302c determines these environmental alerts according to the frequency of occurrence of these environmental alerts, the severity of the failure caused by these environmental alerts in the elevator, and the like. Prioritize.

The disaster alert extraction unit 302d extracts disaster alerts related to the assumed elevator from the disaster prevention map information based on the disaster prevention map of the disaster prevention map database 306d.

For example, when the planned construction site of a building is included in or close to the earthquake occurrence prediction area from the disaster information included in the geographical conditions and the disaster prevention map, the disaster alert extraction unit 302d extracts the earthquake alert as a disaster alert. .. For example, when the planned construction site of a building is included in or close to the flood-damaged area from the disaster information included in the geographical conditions and the disaster prevention map, the disaster alert extraction unit 302d extracts the flood alert as a disaster alert.

When a plurality of these disaster alerts are extracted, the disaster alert extraction unit 302d determines these disaster alerts according to the frequency of occurrence of these disaster alerts, the severity of the failure caused by these disaster alerts in the elevator, and the like. Prioritize.

The building alert extraction unit 302e extracts the building alert related to the elevator assumed from the building BIM model based on the building BIM model acquired by the building information acquisition unit 302a.

For example, when the BIM model of a building includes a living room in which a person lives, the building alert extraction unit 302e calculates the distance between the living room and the elevator. Then, when the distance between the living room and the elevator is within a predetermined range, the building alert extraction unit 302e uses the noise alert and the vibration alert as the building alert because the noise and vibration caused by the elevator operation may be adversely affected in the living room. Extract. Whether or not noise and vibration can be harmful in a living room depends not only on the distance between the living room and the elevator, but also on other information such as the thickness and material of the wall surrounding the living room and the elevator, and the running speed of the elevator. You may judge.

The building alert extraction unit 302e calculates an appropriate transportation amount as an elevator installed in this building based on at least one of information such as the use and layout of the building included in the BIM model of the building, for example. Then, the building alert extraction unit 302e extracts a transportation amount alert indicating the calculated appropriate transportation amount as a building alert.

More specifically, for example, from the use and layout of a building, it is possible to predict the number of people that can be accommodated in the building and the number of people entering and exiting each time zone. That is, for example, if the building is an apartment or condominium, it can be predicted that many people will come and go in the morning and evening, and if it is a commercial facility or the like, many people will come and go during business hours.

When a plurality of these building alerts are extracted, the building alert extraction unit 302e determines these building alerts according to the frequency of occurrence of these building alerts, the severity of the harmful effects on the elevator caused by these building alerts, and the like. Prioritize.

The alert information generation unit 302f generates alert information based on the environmental alert extracted by the environmental alert extraction unit 302c, the disaster alert extracted by the disaster alert extraction unit 302d, and the building alert extracted by the building alert extraction unit 302e.

For example, when environmental alerts such as cold alerts, intense heat alerts, wind damage alerts, and salt damage alerts are extracted, the alert information generation unit 302f indicates that cold region countermeasures, intense heat countermeasures, wind damage countermeasures, salt damage countermeasures, etc. are required. Generate alert information.

For example, when a disaster alert such as an earthquake alert or a flood alert is extracted, the alert information generation unit 302f generates alert information indicating that earthquake countermeasures, flood countermeasures, etc. are required.

For example, when a building alert such as a noise alert, a vibration alert, or a transportation amount alert is extracted, the alert information generation unit 302f outputs alert information indicating that noise countermeasures, vibration countermeasures, etc. are required, and an appropriate transportation amount. Generate alert information to indicate.

When a plurality of these environmental alerts, disaster alerts, and building alerts are received, the alert information generation unit 302f has a priority assigned by the environmental alert extraction unit 302c, the disaster alert extraction unit 302d, and the building alert extraction unit 302e. According to, these environmental alerts, disaster alerts, and building alerts are assigned to a predetermined rank. The predetermined rank may include, for example, a warning rank having a high priority, a caution rank having a low priority, and the like. However, the rank is not limited to two ranks, and may be ranked in a plurality of stages such as levels 1 to 3 and levels 1 to 5.

The alert information generation unit 302f passes the generated alert information and information such as ranking to the display control unit 102c of the control unit 102. At this time, the alert information generation unit 302f may pass only the alert information of the higher rank to the display control unit 102c, or may pass all the alert information to the display control unit 102c. Based on this information, the display control unit 102c causes the display device 114 or the like to display the alert information together with the rank, for example, via the input / output control interface unit 108.

When displaying the alert information of a plurality of ranks, the alert information generation unit 302f generates the alert information so that the alert information is displayed according to the priority. For example, when there are a plurality of alert information related to a disaster, the alert information is generated so that the alert information is displayed in order from the highest level.

Further, when displaying the alert information, the alert information generation unit 302f displays information on the recommended design for the disaster countermeasures indicated by the alert information. For example, when the alert information is "the frequency of typhoons is high", information indicating {vibration isolation measures} is displayed as information on the recommended design. Further, the alert information generation unit 302f is controlled to point to the BIM part associated with the “vibration isolation measure” and display the alert information.

In this way, the alert information generation unit 302f causes the display control unit 102c to display the alert information in which the recommended design information and the BIM part to be the target of the design change are associated with each other.

Various alerts are classified into environmental alerts based on environmental information, disaster alerts based on disaster information, and building alerts based on the BIM model of buildings, but such classifications are merely exemplary. For example, the environmental information stored in the environmental information database 306c may include more information, so that an earthquake disaster alert or a flood damage alert may be extracted from the environmental information. Further, a cold alert, a hot summer alert, a wind damage alert, a salt damage alert, and the like may be extracted based on the disaster prevention map stored in the disaster prevention map database 306d. Further, noise alerts, vibration alerts, transportation volume alerts, and the like may be extracted from the environmental information and the like stored in the environmental information database 306c. For example, the environmental information includes human object information as described above. The human object information includes, for example, the movement conditions of a person in a building, and can be used to calculate an appropriate transportation amount of an elevator.

The request information generation unit 302g generates request information. Specifically, the request information generation unit 302g refers to the request case information database 306a to see if any of the individual BIM parts included in the BIM parts of the elevator are associated with the request case information. Search for. When there is a request case associated with any of the BIM parts, the request information generation unit 302g generates request information including the request case.

The request information generation unit 302g passes the generated request information to the display control unit 102c of the control unit 102. Based on this information, the display control unit 102c causes the display device 114 and the like to display the requested information via the input / output control interface unit 108.

The word "Caution" is attached along with the caution icon. The two alert information may each refer to an elevator site associated with the alert information.

The alert information of the warning rank includes, for example, a building alert based on the BIM model of the building, and since the living room in the building is near the elevator, noise countermeasures and vibration countermeasures such as thickening the wall surrounding the elevator are required. It shows that. Then, this alert information refers to a wall portion surrounding an elevator that is a target of, for example, soundproofing measures. When it is difficult to grasp the situation with the three-dimensional BIM model, it may be displayed in the plan view shown in FIG. 5 (b). In this case, for example, alert information pointing to the wall surrounding the elevator is displayed along with the highlighted room. The alert information of the caution rank includes, for example, a building alert based on the BIM model of the building, and indicates the appropriate transportation volume of the elevator to be installed in the building. And this alert information points to the car part of the elevator, which is a determinant of the transportation volume. In addition, these alert information includes candidates for BIM parts such as soundproof parts and large elevators that are suitable for soundproofing and vibration measures, and for installing elevators with an appropriate transportation volume. You may.

The request information indicates that there was a request in the past to eliminate the morning and evening congestion of the elevator in a building with a predetermined floor area.

The alert information is displayed regardless of, for example, the current specifications of the elevator in order to alert the user of the terminal device 100. In other words, in an elevator that has already taken measures against salt damage, alert information about salt damage measures may be displayed. In addition, an elevator that satisfies the appropriate transportation volume may display alert information indicating the appropriate transportation volume. However, when the elevator specifications satisfy the predetermined conditions, the alert information regarding the item may not be displayed.

On the other hand, the request information is displayed in view of, for example, the current specifications of the elevator. In other words, the request information indicates that there has been some request for the current specifications of the elevator in the past, and countermeasure parts are prepared for this, and it is assumed that there is room for improvement in the elevator. Is displayed.

In order to prevent obstacles that may occur in the elevator indicated by these alert information and request information, the user of the terminal device 100 can press, for example, the "add / change parts" button displayed on the layout screen.

Further, for the alert information, "vibration isolation measures" is displayed adjacent to the check box 312 as information on the recommended design. Then, the alert information points to BIM parts 313 and 314 that should be subjected to anti-vibration measures. As a result, the user can recognize the BIM parts for which anti-vibration measures should be taken.

Further, by indicating "Caution" 315 in the alert information, the user can be made to recognize that the alert information has a lower priority than the alert information indicated as "Warning" 311. Further, for the alert information, a "sway detection sensor" is displayed adjacent to the check box 316 as information on the recommended design. Then, the alert information indicates a place 317 where the "shaking detection sensor" should be installed. This makes it possible to recognize the means for anti-vibration measures.

(Examples of various alerts and countermeasures)
As described above, the environmental alert extraction unit 302c, the disaster alert extraction unit 302d, and the building alert extraction unit 302e extract various alerts related to the elevator design. The alert information generation unit 302f generates alert information based on the extracted various alerts, and also presents countermeasures for various alerts.

Here, more detailed examples of various alerts and more detailed examples of countermeasures against those alerts are shown below. Various alerts and their countermeasures include those described above and those other than those described above. Various alerts and their countermeasures are not limited to the examples shown below.

Depending on the types of alerts shown below, in terms of cost, construction period, and labor, it is better to take measures on the elevator side, when it is better to take measures on the building side, and both the elevator and the building. Various cases can be considered, such as when it is better to take measures on the side of. The alert information generation unit 302f may appropriately present countermeasures for each of the elevator side and the building side. The alert information generation unit 302f may present the cost when measures are taken on the elevator side.

Among various alerts, environmental alerts include, for example, salt damage, humidity, rain, wind, illuminance, temperature, and dust / dust / soil.

When the planned construction site of the building is close to the sea, the alert information generation unit 302f generates an alert regarding salt damage. Although it is desirable to take measures against salt damage on the building side rather than on the elevator side, there are some possible measures that can be taken on the elevator side. The alert information generation unit 302f performs surface treatment, painting, etc. on the appearance part of the design product, etc., the equipment is made of resin instead of metal, and various control panels and external cables connecting the control panels and equipment are used. We will also present measures such as taking similar measures against salt damage.

It can be humid if the planned construction site of the building is close to the sea. The alert information generation unit 302f generates an alert regarding humidity. The alert information generation unit 302f presents rust prevention measures for various elevator supplies and waterproof measures for units such as control panels and motors as humidity measures.

If the elevator is installed outdoors (including semi-outdoors), inflow of rain can occur. The alert information generation unit 302f generates an alert regarding rain. The alert information generation unit 302f presents measures such as measures for drainage and mounting of a control device in a pit portion at a high position.

When the elevator is installed outdoors (including quasi-outdoors), and particularly on a higher floor, the alert information generation unit 302f generates an alert regarding wind. In order to prevent the cables and rails from shaking due to the influence of the wind and stopping the operation of the elevator, the alert information generator 302f should be able to adjust the construction for special environments as a windbreak measure on the elevator side. Advocate. In this case, since the special environment is supported, the alert information generation unit 302f presents the possibility that a separate cost will be incurred.

When the elevator is a viewing elevator equipped with a large window or the like, the inside of the car may become too bright and it may be difficult to see the digital display of the elevator equipment. The alert information generation unit 302f generates an alert regarding illuminance. If there is a corresponding item arranged on the elevator side, it is presented by the alert information generation unit 302f.

In the case of a viewing elevator, an increase in the temperature of the electrical equipment of the elevator may cause problems such as failure to obtain the expected efficiency and shortening the life of the equipment. The alert information generation unit 302f generates an alert regarding the temperature rise. Since the elevator is developed and designed on the assumption that the temperature inside the hoistway is below a certain temperature, it is preferable that measures be taken on the building side. The alert information generation unit 302f presents measures such as attaching a ventilation fan or a glass to the hoistway, changing the wall of the hoistway to one having good thermal conductivity, and changing the skeleton structure.

Depending on the environment, the elevator may be affected by dust, dirt and soil. Accumulation of dust, dirt, dirt, etc. on the board inside the unit may cause malfunction. The alert information generation unit 302f generates an alert regarding dust, dust, and soil, and presents any applicable items arranged on the elevator side.

Among various alerts, disaster alerts include, for example, earthquakes, fires, and typhoons.

In principle, elevators will stop when an earthquake occurs, but it is also desirable for elevators to take seismic measures for each region and measures for building seismic isolation. In this case, the elevator is modeled by incorporating the seismic isolation response by the elevator into the specifications. The alert information generation unit 302f presents that it is possible to add specifications such as earthquake completion operation and long object shaking detectors in high-floor properties.

When there are many wooden buildings in the area, the alert information generation unit 302f generates an alert regarding a fire. Furthermore, if the building has a high floor or is a nursing home, etc., after grasping the needs for using the elevator in the event of a disaster, the alert information generation unit 302f provides a fire prevention section, smoke insulation equipment and heat resistance. We present an elevator design using cables. In addition, the alert information generation unit 302f presents that the operation is such that the elevator is not stopped even in the event of a disaster, and that the operation is changed so that the operation starts immediately after returning.

When the planned construction site of the building is a typhoon-prone area, the alert information generation unit 302f generates an alert regarding the typhoon. For typhoons, the above-mentioned measures such as wind measures, rain measures, and humidity measures are presented as appropriate.

Among the various alerts, building alerts include, for example, noise / vibration, power supply noise, temperature, and legal response requirements for elevators.

Depending on the speed and load capacity of the elevator, the noise and vibration at maximum acceleration of the transformer equipment arranged will vary. In the BIM system 1, a noise reference value is set based on the distance between the living room and the elevator in the building, the type of the wall, the thickness of the wall, and the like, and the noise is compared with the noise of the elevator equipment to be arranged. When the type and structure of the wall are not determined, the BIM system 1 sets the thickness and structure of the wall with temporary values and makes a judgment. When the noise of the arranged item exceeds the standard value, the alert information generation unit 302f generates an alert regarding noise and vibration, and proposes a design change on the building side. Regarding vibration, the alert information generation unit 302f presents a design and an estimate including vibration isolation measures on the elevator side.

Based on the electrical connection design, if there is a risk that a large amount of leakage current may occur due to the connection with the building side or the installation conditions, the alert information generator 302f will generate an alert regarding power supply noise and review the wiring. Present measures to the side. On the elevator side, it is premised that measures with filters are applied to all models, and there is no occurrence of high frequencies on the elevator side.

When the heat conductivity of the hoistway wall is poor or when the temperature of the elevator is expected to rise due to other surrounding environments, the alert information generation unit 302f generates an alert regarding the temperature. The measures are as described above.

Elevators may be required to take legal action. For example, when the distance between the car and the wall of the hoistway is 120 mm or more, it is obligatory to install panels on the elevator side except for the entrance of the hoistway. This is to prevent the elevator door from opening accidentally and causing a person to fall. In this case, since the cost is high, the alert information generation unit 302f makes a proposal such as changing the design of the building frame.

(Example of integrated BIM model creation process)
Next, an example of the process of creating the integrated BIM model in the BIM system 1 of the first embodiment will be described with reference to FIG. FIG. 8 is a flow chart showing an example of a procedure for creating an integrated BIM model in the BIM system 1 according to the first embodiment. The integrated BIM model creation process is performed as part of the BIM control process.

As shown in FIG. 8, the creation condition transmission unit 302x of the terminal device 100 transmits the creation conditions input by the user using the input device 118 or the like to the server device 200 (step S101).

The creation condition receiving unit 202a of the server device 200 receives the creation condition (step S201).

The elevator modeling unit 202b creates BIM parts of the elevator corresponding to the creation conditions received by the creation condition receiving unit 202a by using the part information stored in the parts information database 206a (step S202).

The information providing unit 202c transmits the information of the BIM parts of the elevator created by the elevator modeling unit 202b to the terminal device 100 (step S203).

The communication control interface unit 104 of the terminal device 100 receives the information of the BIM parts of the elevator (step S102).

The integrated modeling unit 102b creates an integrated BIM model in a state in which the BIM parts of one or more elevators received by the communication control interface unit 104 are incorporated into the BIM model of the building stored in the BIM model database 106a (step S103). ).

As described above, the process of creating the integrated BIM model in the BIM system 1 of the first embodiment is completed.

(Example of elevator examination support processing)
Next, an example of the elevator examination support process in the terminal device 100 of the first embodiment will be described with reference to FIG. FIG. 9 is a flow chart showing an example of the procedure of the elevator examination support process in the BIM system 1 according to the first embodiment. The elevator examination support process is performed as a part of the BIM control process, and is performed, for example, when the above-mentioned integrated BIM model creation process is completed. The elevator examination support process is mainly carried out by the functional unit based on the extended function of the terminal device 100.

As shown in FIG. 9, the building information acquisition unit 302a acquires building information such as environmental information, geographic information, and a BIM model of a building (step S301). The environmental information is acquired from the environmental information database 306c of the storage unit 106, the geographic information is acquired from the geographic information database 306b of the storage unit 106, and the BIM model of the building is acquired from the BIM model database 306a of the storage unit 106.

The environmental alert extraction unit 302c extracts an environmental alert from the environmental information acquired by the building information acquisition unit 302a (step S302). If there are a plurality of extracted environmental alerts (step S303: Yes), the environmental alert extraction unit 302c prioritizes them (step S304), and if there is only one extracted environmental alert (step S303: No), the alerts are alerted as they are. It is transmitted to the information generation unit 302f.

For example, the disaster prevention map acquisition unit 302b acquires the latest disaster prevention map including the planned construction site of the building from the disaster prevention map database 502 of the corresponding administrative agency server device 500 based on the geographical information acquired by the building information acquisition unit 302a. Then, the disaster prevention map of the disaster prevention map database 306d stored in the storage unit 106 of the terminal device 100 is updated to the latest one (step S305). However, such processing may be performed in advance before the implementation of the elevator examination support processing. The disaster alert extraction unit 302d extracts a disaster alert from the disaster prevention map (step S306). If there are a plurality of extracted disaster alerts (step S307: Yes), the disaster alert extraction unit 302d prioritizes them (step S308), and if there is only one extracted disaster alert (step S307: No), the alerts are alerted as they are. It is transmitted to the information generation unit 302f.

The building alert extraction unit 302e performs various calculations based on the BIM model of the building acquired by the building information acquisition unit 302a (step S309). The various calculations include, for example, a calculation for calculating the distance between the living room and the elevator, and a calculation for calculating the appropriate transportation amount of the elevator. The building alert extraction unit 302e extracts a building alert based on the calculation result (step S310). If there are a plurality of extracted building alerts (step S311: Yes), the building alert extraction unit 302e prioritizes them (step S312), and if there is only one extracted building alert (step S311: No), the alerts are as they are. It is transmitted to the information generation unit 302f.

When receiving an environmental alert, a disaster alert, a building alert, etc., the alert information generation unit 302f ranks if there are a plurality of received alerts (step S313: Yes) (step S314), and receives only one alert. If there is (step S313: No), alert information is generated based on the received alert without assigning a rank (step S315).

The request information generation unit 302g refers to the request case information of the request case information database 306a, compares it with the information of the individual BIM parts constituting the elevator, and includes the request case information in the individual BIM parts constituting the elevator. Search for whether or not there is an associated item (step S316).

When the request information generation unit 302g has a request case associated with any of the BIM parts constituting the elevator (step S316: Yes), the request information generation unit 302g generates request information including the request case (step S317).

The request information generation unit 302g does not generate request information when there is no request case associated with any of the BIM parts (step S316: No).

The alert information generated by the alert information generation unit 302f and the request information generated by the request information generation unit 302g are sent to the input / output control interface unit 108 by the display control unit 102c. The input / output control interface unit 108 outputs these alert information and request information to, for example, the display device 114 (step S318).

Each functional unit based on the extended function of the terminal device 100 determines whether or not the environmental information, the geographical information, and the building information such as the BIM model of the building have been changed, that is, after the alert information and the request information are generated. It is determined whether or not the building information has been updated (step S319). The update of building information includes, for example, design changes for responding to alert information or request information, in other words, changes and additions of BIM parts.

While the building information is not updated (step S319: No), each functional unit based on the extended function of the terminal device 100 determines whether or not the "confirm" button is pressed by the user, for example, from the layout screen or the like (step). S320). No new process is performed until the "confirm" button is pressed (step S320: No).

When the building information is updated (step S319: Yes), each functional unit based on the extended function of the terminal device 100 repeats the processes of steps S301 to S318. As a result, alert information and request information based on the new building information are generated and displayed on the display device 114.

When the pressing of the "confirm" button is accepted without updating the building information (step S319: No) (step S320: Yes), the communication control interface unit 104 sets the final specifications confirmed. It is transmitted to the server device 200.
