The call correspondence record 501 is updated each time a correspondence event occurs.

  FIG. 6 is a flowchart showing an example of the maintenance target elevator detection procedure in the present embodiment. First, the maintenance necessity degree calculation unit 209 acquires the elevator profile 401 from the elevator profile database 207 (S601), acquires the call correspondence record 501 from the call correspondence database 204 (S602), and stores the floor from the floor-specific activation frequency database 206. Another activation count 305 is acquired (S603). Next, the maintenance necessity level calculation unit 209 calculates the maintenance level for each floor according to Equation 1 described later (S604). Similarly, the maintenance necessity degree calculation unit 209 obtains a cumulative travel distance from the cumulative travel distance database 205 (S605), compares the cumulative travel distance with a predetermined value, etc. The degree (S606) is calculated. Further, the maintenance necessity degree calculation unit 209 calculates the total maintenance degree of necessity according to Equation 2 described later (S607), and stores it in the maintenance degree data table 801 shown in FIG. If the total maintenance target necessity exceeds a specified value (S608), the maintenance necessity calculation unit 209 detects the maintenance target elevator (S609), and the report generation unit 211 generates a maintenance report 901 indicating the maintenance target elevator detection result. Generate (S610). The maintenance report 901 will be described later with reference to FIG. Further, a call correspondence frequency histogram 701 described later in FIG. 7 may be displayed in the maintenance report.

  FIG. 7 is a diagram illustrating an example of a call correspondence frequency histogram according to the number of activations according to the present exemplary embodiment. As illustrated in FIG. 6, the maintenance necessity degree calculation unit 209 draws the call correspondence number histogram 701 based on the number of activations using the acquired data. For log data of all elevators that acquire log data, the vertical axis represents the number of call correspondences 702 obtained from the call correspondence record 501 obtained from the call correspondence database 204, and the horizontal axis obtained from the elevator monitoring log database 205 The total number of activations 703 for each floor is taken and a histogram 704 is drawn. For example, when the number of activations is low, that is, there is a call due to initial failure or unknown operation, etc. while the elevator installation period is short, the number of calls settles down for a while and then the number of activations increases, that is, the elevator When the period from the installation of the “L” is long, the “bathtub curve” -like histogram in which the number of calls due to aging increases increases. The histogram bar to which the elevator to be analyzed belongs is displayed as a bar 705 having a different color from the other bars. In addition, a specified activation count 706 that is an upper limit value for which maintenance is recommended is displayed. The specified number of activations 706 may be determined by a manufacturer recommended value that is a threshold for deterioration of component performance, or may be determined by an experience value such as an actual value that increases the number of calls to other elevators. By displaying the call response frequency histogram 701, the customer can grasp the position of the owned elevator in the elevator group, and can reduce the time required for the work for determining the maintenance time.

  “Necessary maintenance level by floor (%) = current total number of activations (times) / specified number of activations (times) × 100” (Equation 1) is a formula for calculating the degree of maintenance necessary based on the total number of activations by floor. It is a formula which shows an example. This formula shows how much maintenance level of an elevator is. As the value approaches 100%, the necessity for maintenance increases, and when it exceeds 100%, it indicates that maintenance is recommended immediately. This formula is calculated for each floor, for example, for the first floor, the second floor, the third floor,.

  "Comprehensive / Maintenance Necessity (%) = MAX (MAX (Maintenance Necessity of the First Floor (%), Maintenance Necessity of the Second Floor (%), ..., Maintenance Necessity of the Nth Floor (%)), ... ... (Cumulative mileage maintenance necessity level) ”(Formula 2) is an expression showing an example of a calculation formula for the total / maintenance degree. A plurality of maintenance needs for the cumulative number of activations for each floor shown in Equation 1 are calculated for each floor. Furthermore, the maintenance necessity level is calculated for each of the total travel distance, the total travel time, and other indicators. Therefore, the total value of the plurality of maintenance needs is the total / maintenance necessity. The total maintenance necessity is the maximum value of the plurality of maintenance needs.

  FIG. 8 is a diagram illustrating an example of the maintenance necessity data table 801 in the present embodiment. One elevator table is provided for each elevator ID 302. The maintenance necessity level calculation unit 209 stores the calculated maintenance level in the main table of the maintenance level database 208. This table is based on the floor 802, the cumulative number of activations 803 calculated by the floor-specific activation number calculation unit 202, the maintenance necessity level 804 based on the total number of floor-specific activations calculated by the maintenance level calculation unit 207, and the total travel distance. A maintenance necessity degree such as a distance maintenance necessity degree 805 and a total / maintenance necessity degree 806 calculated by the maintenance necessity degree calculation unit 209 are provided.

  FIG. 9 is a diagram illustrating an example of a maintenance report screen according to the present embodiment. This report enables salespeople or maintenance personnel to identify elevators that require maintenance. The report generation unit 211 acquires the calculation result of the maintenance necessity level calculation unit 209 and generates a maintenance report 901 for sales staff. The salesperson maintenance report / detection result list 901 includes a maintenance target elevator detection result list 902. The maintenance target elevator detection result list 902 has a target building name 402, a target elevator ID 302, and a total / maintenance necessity level 806, and presents the maintenance level of each elevator that has acquired log data. Using the elevator ID 302 as a key, the report generation unit 211 acquires and draws the total maintenance necessity level 806 of the target elevator and the building name 402 where the elevator is installed from the building profile 401. The maintenance necessity calculation unit 209 detects the maintenance target elevator when the maintenance necessity exceeds the threshold. For example, when the maintenance necessity threshold is set to “90%”, the target elevator information is shown in bold and an alert mark 903 is presented. When the office computer 103 receives an input specifying a specific elevator from an input unit (not shown) such as a mouse, the report generation unit 211 generates and outputs a maintenance report / elevator detail 1001 described later in FIG.

  FIG. 10 is a diagram showing an example of a maintenance report / elevator details 1001 screen in the present embodiment. This report enables salespeople or maintenance personnel to grasp detailed information on elevators that require maintenance. When the sales office computer 103 receives an input specifying a specific elevator from an input unit (not shown) such as a mouse, the report generation unit 211 acquires the calculation result of the maintenance necessity level calculation unit 209 corresponding to the elevator, A sales employee maintenance report / detection result list 1001 is generated. The sales employee maintenance report / detection result list 1001 includes an elevator ID 302, an object building name 402, elevator information 410 acquired from the elevator profile 401, an elevator number (not shown), etc., an overall maintenance necessity level 806, and elevator detailed information 1003. Have The elevator detailed information 1003 includes, for example, a floor-by-floor start count graph 1004 and a maintenance necessity reason column 1005. The report generation unit 211 acquires the result calculated by the floor-specific activation frequency calculation unit 202 and generates the floor-specific activation frequency graph 1004. The floor-specific activation frequency graph 1004 has a floor-specific activation frequency 1006 on the vertical axis, a year 1007 on the horizontal axis, and a data legend 1008, and has a line graph 1009 of activation frequency by floor. If this elevator is an elevator that is detected to have a high degree of maintenance, the report generation unit acquires the reason for maintenance of this elevator from the maintenance necessity reason data table (not shown) included in the maintenance necessity database 210, and performs maintenance. Presented in the necessary reason column 1005. The maintenance necessity level is determined from, for example, the attribute of the maintenance necessity level that takes the maximum value when the total / maintenance degree is calculated according to Equation 2. For example, if the total / maintenance necessity level is calculated because the cumulative number of activations on the third floor has reached the prescribed number of activations, it is indicated that “the cumulative number of activations on the third floor has reached the prescribed number of activations”.

According to the present embodiment, it is possible to detect the necessity of maintenance by intensive use of a specific floor from the elevator monitoring log. It is also possible to generate a screen that presents the “maintenance necessity level”. As a result, it is possible to obtain an effect of reducing the work time and cost required for maintenance personnel to detect an elevator that requires maintenance.
<Example 2>
In the present embodiment, in addition to the elevator management system described in the first embodiment, a comparative analysis with other similar buildings is performed, and the degree of maintenance is calculated. In addition, a screen that presents a “necessity of maintenance” in consideration of comparison with other similar buildings is generated. As a result, it is possible to obtain an effect of reducing the work time required for the maintenance staff or the customer to detect an elevator that requires maintenance by comparison with a similar building.

  FIG. 12 is a flowchart illustrating an example of a maintenance target elevator calculation procedure in the present embodiment. First, the report generation unit 211 acquires a maintenance target elevator detection result generated according to, for example, the flowchart illustrated in FIG. 6 (S1201), and the maintenance target elevator detection indicating the maintenance necessity order of the maintenance target elevator described later in FIG. A result list 1304 is generated (S1202). Next, the report generation unit 211 calculates a maintenance recommended time 1502 (S1203), and calculates a cost saving effect 1503 (S1204). The recommended maintenance time 1502 is calculated as a time predicted to reach the specified number of activations 706 when the target elevator is operated with the same transition as in the past, for example, from the call correspondence histogram 701 in FIG. The cost saving effect 1503 is obtained from the data acquired from the maintenance cost data table 12B01, corresponding costs when maintenance is not performed, that is, maintenance costs 12B07 when certain maintenance described later in FIG. That is, a post-failure cost 12B08 when certain maintenance described later in FIG. 16 is not performed is compared to calculate how much yen can be saved when the maintenance is performed. Next, the report generation unit 211 acquires maintenance records / business records of the corresponding elevator from the maintenance record management server 1104 and the business record management server 1103 (S1205). If the report generation unit 211 confirms that there is no record of performing maintenance on the corresponding elevator from the maintenance record, and that there is no record that the maintenance corresponding to the corresponding elevator is being proposed in the business record, the maintenance target device / detection A report output date 1302 and a target area 1303 are added to the result list 1304, and a maintenance report 1301 described later in FIG. 13 or a customer maintenance report 1501 described later in FIG. 15 is drawn and output (S1206).

  “Cost saving effect (yen) = post-failure cost 12B08 (yen) −maintenance cost 12B07 (yen)” (formula 3) is an expression showing an example of a calculation formula for the cost saving effect. This formula calculates the cost saving effect when a certain maintenance is performed.

The maintenance content 12B04 of the maintenance location 12B03 of a certain elevator model 401, for example, the maintenance content 12B04, for example, rust removal processing, for example, the frequent occurrence of failure 12B05 is a reference number of times that some trouble frequently occurs when maintenance is not performed. The maintenance execution guideline 12B06 has the number of times of use that is a maintenance execution guideline for preventing problems. The data table 12B01 has a maintenance cost 12B07 when this maintenance is performed and a post-failure cost 12B08 when the maintenance is not performed.

  FIG. 13 is a diagram showing an example of a maintenance report screen 1301 in the present embodiment. This report 1301 makes it possible for salespeople or maintenance personnel to grasp the elevators that need maintenance in the area they are in charge of in order of maintenance need, and reduce the work hours required to determine the elevators that should be prioritized for maintenance. It becomes possible. The report generation unit 211 acquires the calculation result of the maintenance necessity level calculation unit 209 and generates this report 1301. The report 1301 includes a report output date 1302, a target area 1303, and a maintenance target elevator detection result list 1304 in order of maintenance necessity. The report generation unit 211 acquires the building location address 403 from the elevator profile 401, extracts only elevators in the target area, and generates the maintenance target elevator detection result list 1304. The maintenance target elevator detection result list 1304 has a maintenance necessity level 1305, a target building name 402, a target elevator ID 302, and a maintenance level 806. When the office computer 103 receives an input for designating a specific elevator from an input unit (not shown) such as a mouse, the report generation unit 211 generates and outputs a maintenance report / elevator detail 1401 described later in FIG. The detected elevator list for maintenance may be converted into a text format by a mail server (not shown), and may be sent to a maintenance staff or a sales staff every time analysis is performed, for example, every day.

  FIG. 14 is a diagram showing an example 1401 of a maintenance report / elevator details screen in the present embodiment. This report 1401 has a target area 1303 and a maintenance record / business record column 1402 in addition to the maintenance report 1001 shown in FIG.

  FIG. 15 is a diagram showing an example 1501 of a customer maintenance report screen in the present embodiment. With this report 1501, the customer who is the owner of the elevator, such as a building owner or a real estate agent, can grasp the maintenance necessity of the elevator that he / she owns and can reduce the work time required for determining the maintenance execution. . The report generation unit 211 acquires the calculation result of the maintenance necessity level calculation unit 209 and generates this report 1501. This report 1501 includes report output date 1302, target building name 402, target elevator information 1002, maintenance necessity 806, maintenance recommended time 1502, cost saving effect 1503, comparison graph 1504 with an elevator of a similar building, building scale 1505, building A type 1506 and a target area 1303 are included. Further, a print button 1509 and a logout button 1510 in the case of a web application may be provided. The customer maintenance report 1501 may be output by a computer carried by a salesperson, or the customer may input an output instruction by himself as a web application or the like. The report generation unit 211 outputs the recommended maintenance time calculated in S1203 and the cost saving effect calculated in S1204 to the recommended maintenance time 1502 and the cost saving effect 1503 when renewed, respectively.

  A comparison graph 1504 with an elevator of a similar building is, for example, a floor-specific activation frequency histogram 701. At this time, the report generation unit 211 narrows down the building size 1505 determined from large and small based on the floor area, building type such as hotel, office, commercial facility, school, hospital, similar buildings limited by the target area 1507, etc. It is also possible to generate a floor-specific activation frequency histogram 701. The prescribed activation count 706 differs depending on the area 1507 where the target elevator is installed. For example, it is characterized by rapid deterioration of the rope due to salt damage if it is along the sea, and due to sulfur if it is hot springs. Further, the recommended maintenance period varies depending on the building type 1506. For example, it is suitable for the maintenance period because there is little use of the elevator during the summer and winter holidays for schools, and it is not suitable for the summer and winter holidays, which is the busy season for hotels, and it is desirable to maintain during the off season. Therefore, a comparison graph 1504 with elevators of similar buildings focused on similar buildings enables the customer to grasp the position of owned elevators in the elevator group of similar buildings, and to reduce the time required for the work to determine the maintenance time It becomes possible.
