  The hazard setting unit 33e sets whether or not to alert the danger notifying unit 33c when the maintenance staff 23 passes through the same dangerous part after the next time.

  FIG. 4 is a block diagram showing the configuration of the monitoring center in the same embodiment.

  In the monitoring center 22, a Web server 41 and a plurality of PCs 42a, 42b, 42c... Are installed.

  The Web server 41 is connected to the communication network 21 via a GW (Gateway) (not shown), and can communicate with each other as an external device including the maintenance terminal device 24. Here, as a control device of the monitoring center 22 Exists. The PCs 42a, 42b, 42c... Are connected to the Web server 41 via a communication line 43 such as a LAN (Local Area Network). The PCs 42a, 42b, 42c,... Are terminal devices used by each operator as a monitoring console.

  FIG. 5 is a block diagram showing the configuration of the Web server in the monitoring center in the same embodiment.

  The Web server 41 includes a control unit 51, a storage unit 52, various databases 53, a communication unit 54, and an interface (I / F) 55.

  The control unit 51 includes a CPU, and executes various processes by reading a program 52a stored in the storage unit 52. Further, the control unit 51 is provided with a database search unit 51a, an information collection unit 51b, and an information provision unit 51c as functional units for realizing the present system.

  The database search unit 51a searches the map of the designated area from the article database 53a included in the various databases 53, and also searches the map database 53c for the positions of the articles 11a, 11b, 11c,. Further, the database search unit 51 a searches the maintenance worker database 53 b from the terminal ID or the like sent from the maintenance terminal device 24 and identifies the maintenance worker 23 having the maintenance terminal device 24.

  The information collection unit 51b collects hazard information related to dangerous spots existing around each property. The hazard information collected by the information collection unit 51 b is stored in a hazard management table 52 b provided in the storage unit 52. Specifically, as shown in FIG. 6, hazard information includes “position”, “title”, “content”, “attachment”, “weather”, etc., as information related to the dangerous place. Each item is stored in the hazard management table 52b.

  When the maintenance staff 23 heads for an arbitrary property to be inspected, the information providing unit 51c reads out hazard information related to a dangerous location around the property from the hazard management table 52b and provides (transmits) the hazard information to the maintenance terminal device 24. )

  The storage unit 52 includes a memory such as a ROM and a RAM, and stores various data necessary for the processing of the control unit 51 in addition to the program 52a. In addition, the storage unit 52 stores the name of the maintenance staff 23 heading for rescue and the estimated arrival date and time.

  On the other hand, the various databases 53 provided in the Web server 41 include a property database (property DB) 53a, a maintenance worker database (maintenance worker DB) 53b, a map database (map DB) 53c, and the like. Note that these databases 53a to 53c are actually provided in the storage unit 52 or the like.

  The property database 53a stores information on each property 11a, 11b, 11c. Specifically, as shown in FIG. 8, the identification number (property ID) of each property, the property name, the address, the number of elevators installed in the property, information on the number of units, and the like are stored.

  The maintenance staff database 53b stores information on each maintenance staff. Specifically, as shown in FIG. 8, each maintenance person's identification number (maintenance person ID), name, affiliation (office), information of the maintenance terminal device 24 possessed by the maintenance person (terminal ID and Address, telephone number, etc.), current location and attribute information of maintenance personnel, status information, etc. are stored.

  The “current position” is detected by using a GPS function (GPS module 36) provided in the maintenance terminal device 24. The “attribute information” includes the type of maintenance personnel. The job categories are broadly classified into “inspectors” who mainly perform general periodic inspections and “statutory inspectors” who have legal inspection qualifications. Legal inspectors can also serve as inspectors, but the number is generally smaller than inspectors. “Status information” is information indicating the work status of maintenance personnel, and includes “working” and “moving”.

  The map database 53c stores map information (image information) for each area. Specifically, as shown in FIG. 9, a plurality of map information is classified and stored according to the scale ratio. In this case, the higher the scale ratio of the map, the wider the area, and the lower the scale ratio, the narrower the area.

  The communication unit 54 provided in the Web server 41 transmits and receives data to and from the elevators 12a, 12b, 12c... Installed in the respective properties 11a, 11b, 11c. The interface 55 performs data input / output processing with the PCs 42a, 42b, 42c... Connected to the Web server 41.

  The Web server 41 can be accessed via the communication network 21 from the maintenance terminal device 24 or from a PC in a business office in each area (not shown).

  Next, the operation of this system will be described separately for (a) processing at the time of hazard information registration and (b) processing at the time of using hazard information.

(A) Processing at the time of hazard information registration FIG. 10 is a flowchart showing the processing operation at the time of hazard information registration of this system. The left side shows the processing of the maintenance terminal device 24, and the right side shows the processing of the monitoring center 22. The processing of the maintenance terminal device 24 is executed by the control unit 33 in the maintenance terminal device 24 reading the program 35a. The processing of the monitoring center 22 is executed when the control unit 51 in the Web server 41 reads the program 52a.

  For example, when the maintenance staff 23 visits each property during regular inspections and finds a dangerous spot around these properties, the hazard map Web managed by the company's monitoring center 22 is accessed for the hazard. Register information.

  That is, firstly, the maintenance staff 23 accesses the hazard map Web through the maintenance terminal device 24 by a predetermined operation, and makes a hazard information registration request (step A11). When there is an access to the hazard map Web, the Web server 41 provided in the monitoring center 22 refers to the maintenance staff database 53b and performs user authentication of the accessor (step B11). When it is authenticated that the access person is a regular maintenance person 23, the Web server 41 permits the registration of the hazard information, and the hazard information registration screen is displayed on the maintenance terminal device 24 of the maintenance person 23 who is the access person. 60 is displayed (step A12).

  As shown in FIG. 13, the registration screen 60 includes a plurality of items 61 to 65 for registering “location”, “title”, “content”, “attachment”, and “weather” as information on the dangerous place. Is provided.

  The place item 61 is an item for registering position information (such as an address) indicating the place of the dangerous place. The title item 62 is an item for registering the title (outline) of the dangerous part. The content item 63 is an item for specifically registering what danger is present. The attached item 64 is an item for registering attached information such as a photograph, a moving image, and a sound of a dangerous place. The weather item 65 is an item for registering the relationship between the dangerous place and the weather condition. The maintenance staff 23 registers hazard information by appropriately inputting information corresponding to these items 61 to 65 by a predetermined operation (step A13).

  Furthermore, along with the registration of the hazard information, the Web server 41 displays a hazard map 71 of the area including the dangerous part on the monitoring screen 70 as shown in FIG. 14 and the registered contents at an arbitrary position on the hazard map 71. Confirmation screens 72 and 73 are displayed (step B13). The monitoring screen 70 can be viewed on any PC of the PCs 42a, 42b, 42c... Connected to the Web server 41. In the figure, reference numeral 74 denotes an area search screen. By inputting an arbitrary area as a search condition, the hazard map 71 of the area can be displayed.

  Here, 81 in the figure is a property mark indicating the position of the property (the building where the elevator is installed), 82 is a maintenance worker mark indicating the location of the maintenance worker, and 83 is a caution mark indicating the location of the dangerous location. The registered content confirmation screens 72 and 73 display the contents of the hazard information registered by the maintenance staff 23 through the registration screen 60. As a result, the operator in the monitoring center 22 confirms the registered contents of the hazard information in real time, and if there are any unclear points in the registered contents, for example, the operator can contact the registrant maintenance staff 23 and correct it appropriately. it can.

  If there is no problem with the registered contents, the Web server 41 collects the hazard information registered by the maintenance staff 23 and stores it separately for each item in the hazard management table 52b shown in FIG. 6 (step B15).

  If there is another dangerous point (No in Step A14), the maintenance staff 23 can continue to register in the same manner as described above. If there is another dangerous place (Yes in step A14), the connection with the hazard map Web is blocked by a predetermined operation, and the registration process here is completed.

  Although the description has been given here assuming that the hazard information is registered using the maintenance terminal device 24, the registration can also be performed through a PC installed in a maintenance management company or business office, for example.

  (B) The process when using hazard information will be described separately.

  FIG. 11 is a flowchart showing the processing operation when the hazard information of this system is used. The left side shows the processing of the maintenance terminal device 24, and the right side shows the processing of the monitoring center 22. The processing of the maintenance terminal device 24 is executed by the control unit 33 in the maintenance terminal device 24 reading the program 35a. The processing of the monitoring center 22 is executed when the control unit 51 in the Web server 41 reads the program 52a.

  For example, when a disaster such as an earthquake occurs and the maintenance staff 23 inspects a property outside the jurisdiction area or when inspecting a property within the normal jurisdiction area, the hazard function button shown in FIG. It is assumed that the hazard function is activated by pressing 25.

  First, the maintenance staff 23 notifies the monitoring center 22 of the dispatch to the inspection target property through the maintenance terminal device 24 (step A21). As a contact method, for example, information such as a property to be inspected and a dispatch time are transmitted to the monitoring center 22 through an unillustrated dispatch contact screen, or the monitoring center 22 is contacted using e-mail or the like. But it ’s okay. In response to this notification, the Web server 41 provided in the monitoring center 22 searches the maintenance worker database 53b from the terminal ID or the like, identifies the maintenance worker 23, and monitors the movement (step B21).

  The maintenance terminal device 24 owned by the maintenance staff 23 has a GPS function, and the position information of the maintenance staff 23 detected by the GPS function is periodically sent to the monitoring center 22 (step A22). When the Web server 41 receives the position information of the maintenance staff 23 from the maintenance terminal device 24, the Web server 41 searches the route from the current position of the maintenance staff 23 to the property to be inspected with reference to the map database 53c (step B22). Is transmitted to the maintenance terminal device 24 held by the maintenance staff 23 (step B23).

  Here, the Web server 41 refers to the hazard management table 52b and determines whether or not there is a dangerous place on the route (step B23). Specifically, it is determined whether there is a dangerous place on the route based on the location information registered as hazard information. When a plurality of routes are searched, the presence / absence of a dangerous point is checked for each route. When the dangerous part exists (Yes in Step B24), the Web server 41 transmits hazard information regarding the dangerous part to the maintenance terminal device 24 held by the maintenance staff 23 (Step B24).

  On the other hand, the maintenance terminal device 24 displays the map received from the Web server 41 on the display unit 32 (step A23). This map includes a route from the current position of the maintenance staff 23 to the property to be inspected. In addition, although demonstrated here as a map being sent from the Web server 41, you may acquire and display a map from an external map site etc., for example.

  When the hazard information about the dangerous location is sent from the Web server 41, the maintenance terminal device 24 displays the dangerous location on the map based on the hazard information, and visually notifies the maintenance staff of the location of the dangerous location. (Step A24).

  Specifically, when the maintenance staff 23 heads for the property to be inspected, a route display screen 80 as shown in FIG. 15 is displayed on the display unit 32 of the maintenance terminal device 24. The route display screen 80 includes a map 81 having an arbitrary magnification including a route from the current position of the maintenance staff 23 to the property to be inspected. 82 in the figure is a current position mark, which is displayed at the current position of the maintenance staff 23. Reference numeral 83 denotes a direction mark indicating the traveling direction of the maintenance staff 23. The current position of the maintenance staff 23 and the traveling direction during movement are detected by a GPS function provided in the maintenance terminal device 24. 84 is a property mark, which is displayed at the location of the property to be inspected by the maintenance staff 23.

  If there is a dangerous spot on the route from the current position of the maintenance staff 23 to the property to be inspected, a star-shaped caution mark 85 is displayed at the location of the dangerous spot. Note that the shape of the caution mark 85 is not limited to a star shape, and may be any shape as long as it can visually attract attention. The color and size are also arbitrary. The same applies to the current position mark 82, the direction mark 83, and the property mark 84, and the display form such as shape, color, and size is arbitrary. In addition, a caution regarding the dangerous location indicated by the caution mark 85 on the map 81 is displayed in the caution area 86 provided at the lower part of the screen.

  Here, while the maintenance staff 23 is moving, when the maintenance terminal device 24 detects that the maintenance staff 23 has approached the dangerous location at the destination, the buzzer sound generator 34 is activated to generate a buzzer sound of a predetermined volume. Is generated to call attention to the dangerous part (step A25). Note that the approach of the maintenance staff 23 to the dangerous location can be determined based on the location information of the maintenance staff 23 detected by the GPS function and the location information of the dangerous location included in the hazard information.

  FIG. 12 is a flowchart showing details of the danger notification process executed in step A25.

  There are places where the risk is high depending on the weather conditions. For example, an intersection where the outlook deteriorates on a rainy or snowy day. As shown in FIG. 6, weather conditions that should be noted at a dangerous location are registered in the hazard management table 52b in advance.

  The maintenance terminal device 24 acquires current weather information around the dangerous location by connecting to a weather site provided by the Japan Meteorological Agency or the like via the Internet, for example (step A31). The timing for acquiring the weather information may be, for example, when the maintenance staff 23 is dispatched at Step A21 or when the map is displayed at Step A24. Further, as a method for acquiring weather information, it may be acquired by connecting to the weather site by an explicit operation of the maintenance staff 23, or may be acquired by automatically connecting to the weather site programmatically.

The maintenance terminal device 24 compares the current weather information acquired from the weather site with the weather condition of the dangerous location registered in advance (step A32). As a result, when the current weather information does not match the weather condition of the dangerous location (No in step A32), the maintenance terminal device 24
It is determined whether the maintenance staff 23 has approached the first range E1 from the danger point (step A33).

  FIG. 16 is a diagram for explaining a range set as an approach determination criterion. The first range E1 is set to a radius of M meters from the center of a dangerous spot (see the property mark 84 and the caution mark 85 in the figure) around the property to be inspected as a normal approach determination criterion. When the maintenance staff 23 approaches within the first range E1 (Yes in Step A33), the maintenance terminal device 24 generates a buzzer sound with the first volume V1 from the buzzer sound generation section 34, and sends it to the maintenance staff 23. Attention is drawn (step A34).

  On the other hand, if the current weather information matches the weather condition of the dangerous spot, that is, for example, the current weather information around the dangerous spot is “rain”, and “rain” is registered as the weather condition of the dangerous spot. If (Yes in step A32), the maintenance terminal device 24 uses the second range E2 that is set wider than the first range E1, and whether or not the maintenance staff 23 approaches the second range E2. Is determined (step A35).

  As shown in FIG. 16, the second range E2 is set to a radius of N meters from the center of the dangerous location (location indicated by the caution mark 85 in the figure) as an approach determination criterion when the weather conditions match. (N> M). When the maintenance staff 23 approaches within the second range E2 (Yes in Step A35), the maintenance terminal device 24 uses the buzzer sound generating unit 34 at the second volume V2 set higher than the first volume V1. By generating a buzzer sound, the maintenance staff 23 is alerted (step A36). In this way, when the current weather information around the dangerous spot matches the pre-registered weather conditions, attention is drawn with emphasis earlier than usual.

  The first range E1 and the second range E2 are set in consideration of the moving speed of the maintenance staff 23. In this case, the higher the moving speed, the wider the first range E1 and the second range E2. For example, the first range E1 and the second range E2 are set wider and earlier when the maintenance worker 23 is moving by car and when moving by foot. Attention will be drawn to. The moving speed of the maintenance staff 23 can be determined by following the current position sequentially detected by the GPS function.

  In addition, during the movement of the maintenance staff 23, attention is drawn to a dangerous place that exists ahead of the traveling direction. Therefore, for example, as shown in FIG. 16, even when a dangerous spot of another property (see the property mark 84 ′ and the caution mark 85 ′ in the figure) is nearby, No attention is given to the danger area. As a result, it is possible to prevent the maintenance staff 23 from being confused by alerting the maintenance staff 23 during the movement of the maintenance staff 23.

  In addition to generating a buzzer as a way to call attention, for example, “The intersection ahead of ** has poor visibility and many accidents. Please proceed with caution.” A warning message regarding the dangerous part may be displayed on the display unit 32.

  Further, a vibration function and a light function that are provided as standard in the maintenance terminal device 24 may be used, or a combination of these functions including a buzzer sound and a warning message display may be used to call attention. .

  When displaying a warning message, the presence / absence of emphasis is switched depending on the message content, size, color, and the like. When using the vibrate function, the presence or absence of emphasis is switched according to the vibration intensity or vibration pattern. When the light function is used, the presence or absence of emphasis is switched according to the light intensity of the runt or the lighting pattern.

  Furthermore, it is possible to call attention using a voice function that is provided as a standard in the maintenance terminal device 24. Specifically, the warning message described above is converted into voice data, voice is output through a speaker (not shown), and the presence / absence of emphasis is switched depending on the content and volume of the voice output. In addition, when using the voice function, detailed notes regarding the dangerous part may be output as a voice.

  Returning to the flowchart of FIG. 11, the maintenance terminal device 24 displays a hazard setting screen 87 as shown in FIG. A26). The hazard setting screen 87 is provided with a check unit 88 for setting whether or not to alert when passing through the same dangerous spot after the next time. When the maintenance staff 23 sets not to call attention through the check unit 88, the maintenance terminal device 24 stores the setting information at that time in the storage unit 35, and when the same danger point is passed after the next time, Refer to the setting information to prohibit alerting.

  When the maintenance staff 23 arrives at the site (the property to be inspected), a notification that the maintenance terminal device 24 has arrived at the site enters the monitoring center 22 (step A27). As a contact method, for example, information such as the time of arrival at the property to be inspected is transmitted to the monitoring center 22 through a screen for on-site contact (not shown), or the monitoring center 22 is notified using e-mail or the like. That's fine. Alternatively, the information of the two-dimensional code provided at an arbitrary place of the property (such as an elevator hall) may be read by the maintenance terminal device 24 and the read information may be sent to the monitoring center 22. The information of the two-dimensional code includes information such as the address of the property and the model of the elevator.

  In response to such notification, the Web server 41 provided in the monitoring center 22 searches the maintenance staff database 53b from the terminal ID and the like to determine that the maintenance staff 23 has arrived at the site (step B26). Since the Web server 41 monitors the current position of the maintenance staff 23, it is possible to know that the maintenance staff 23 has arrived at the site without such a contact.

  When the maintenance staff 23 arrives at the site, the Web server 41 transmits a control signal for turning off the GPS function to the maintenance terminal device 24 of the maintenance staff 23 (step B27). In response to this control signal, the maintenance terminal device 24 turns off the GPS function (step A28). That is, while the maintenance staff 23 arrives at the work site and performs the inspection work, the current position of the maintenance staff 23 is known, and thus the GPS function is turned off to prevent battery consumption of the maintenance terminal device 24. When it is detected that the maintenance staff 23 has finished the inspection work, a control signal for turning on the GPS function is transmitted.

  Here, the GPS control signal is sent from the Web server 41 to forcibly turn off the GPS function of the maintenance terminal device 24. For example, by sending a message screen 89 as shown in FIG. 18 to the maintenance terminal device 24, The GPS function may be turned off by the operation of the maintenance staff 23. In this case, the maintenance staff 23 needs to turn on the GPS function when the inspection work is completed.

  In this way, for example, when inspecting a property outside the jurisdiction area due to the occurrence of a disaster such as an earthquake, or when inspecting a property within the normal jurisdiction area, based on the hazard information related to the pre-registered hazard location A dangerous spot (caution mark 85) is displayed on the map. Therefore, even if the maintenance staff 23 does not go out after checking the dangerous place in advance, it can proceed with caution while checking the presence of the dangerous place on the terminal screen during the movement. Further, when the maintenance staff 23 approaches the dangerous place, attention is alerted by a buzzer sound or the like, so that an accident at the dangerous place can be prevented.

  Here, the hazard information in the present embodiment is information collected from a large number of maintenance personnel 23 who are inspecting in each region, and is directly related to each property that the maintenance personnel 23 perform maintenance inspections. is there. Therefore, unlike a hazard map in which a general danger point is described, it can be used effectively when the maintenance staff 23 dispatches each property for inspection work.

  In the above embodiment, the case where the elevator is inspected and maintained has been described as an example. When going out, the hazard function provided in the maintenance terminal device 24 can be used to safely head for the site.

  According to at least one of the embodiments described above, a terminal device and a maintenance management system are provided that can grasp the existence of a dangerous point and go to safety without checking in advance when maintenance personnel are dispatched to the site. be able to.

  In addition, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
