Description

Technical Field

[0001] The present invention relates to an elevator control system, a remote control server, and a remote control method.

Background Art

[0002] Depending on the operating conditions of an elevator, such as the operating location and the operating time zone, the time from when the door opens until it closes (hereinafter referred to as the "door opening time") becomes shorter or longer. For example, wheelchair users take time to board and alight from the car. Therefore, in response to a wheelchair call, the door opening time becomes longer than a predetermined fixed time, that is, the door opening time set value. Alternatively, during the commuting time zone, the number of users boarding the car increases. Therefore, the door opening time may also become longer than the door opening time set value. Thus, a technique for controlling the door opening time of an elevator according to the operating conditions of the elevator is disclosed in Patent Document 1 below.

[0003] This Patent Document 1 describes that "in a door time shortening elevator that detects boarding and alighting passengers and controls the opening and closing of an elevator door to shorten unnecessary opening time, a car side door sensor that detects boarding and alighting passengers approaching the elevator door in the car, a multi-beam door sensor that detects boarding and alighting passengers when the door opens and closes, a landing side door sensor that detects boarding and alighting passengers near the door of the landing, and a load sensor in the car are provided, and based on the outputs of the car side door sensor, the multi-beam door sensor, and the landing side door sensor, the door time, which is the time from when the door opening is completed until the closing operation starts, is determined."

Summary of the Invention

Problems to be Solved by the Invention

[0005] As described above, the technology described in Patent Document 1 controls the door opening time according to the time it takes for passengers to pass through the elevator doors, as detected by the car-side door sensor, multi-beam door sensor, and landing-side door sensor. In other words, the elevator described in Patent Document 1 controls the door opening time each time the doors open when a user uses the elevator. However, when an elevator administrator, or user of the elevator control system, sets the door opening time, they often set the time recommended by the elevator control system as the door opening time setting value. Furthermore, elevators generally generate a recommended door opening time value based on the door opening time. Therefore, the technology described in Patent Document 1 had the problem that the amount of work required for the administrator to check the recommended door opening time value generated each time a user uses the elevator and set the door opening time setting value was enormous.

[0006] The present invention was made to solve the above problems, and the object of the present invention is to provide an elevator control system that aggregates and outputs recommended values ​​for door opening time. [Means for solving the problem]

[0007] The elevator control system according to the present invention comprises an elevator that outputs a recommended door opening time value selected based on the door opening time measured each time the door opens and a preset door opening time setting value; a remote control terminal that controls the elevator door opening operation based on the door opening time setting value; and a remote control server that transmits the door opening time setting value to the remote control terminal. The remote control server includes an aggregation unit that aggregates the recommended door opening time values ​​at time intervals specified via the terminal device based on a comparison result obtained by comparing the door opening time setting value and the recommended door opening time value within a time range specified via the terminal device; and an output unit that outputs information regarding recommended values ​​that can be set as door opening time setting values ​​for the elevator to the terminal device. [Effects of the Invention]

[0008] With this invention, recommended door-opening time values, aggregated according to a specified time interval via a terminal device, are output to the terminal device, allowing the user to check the aggregated recommended door-opening time values. Other issues, configurations, and effects will be clarified by the following description of the embodiments. [Brief explanation of the drawing]

[Figure 7] This flowchart shows the procedure for aggregating recommended door opening time values ​​in an elevator control system according to one embodiment of the present invention. [Modes for carrying out the invention]

[0010] Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings. In this specification and drawings, components having substantially the same function or configuration are denoted by the same reference numerals, and redundant descriptions are omitted.

[0011] <Embodiment> [Example of an elevator control system configuration] First, the configuration of the elevator control system according to this embodiment will be described. Figure 1 is a block diagram showing an example configuration of the elevator control system 100 according to this embodiment. As shown in Figure 1, the elevator control system 100 comprises an elevator 10, a remote control terminal 20, a remote control server 30, and a screen display terminal 40. The elevator 10 is connected to the remote control terminal 20 by a communication line 50. The remote control terminal 20 is connected to the remote control server 30 by a communication line 60. The remote control server 30 is connected to the screen display terminal 40 via a communication line 70. The communication line 50 uses a LAN constructed in the building where the elevator 10 is installed, and the communication lines 60 and 70 use the internet or the like.

[0012] As shown in Figure 1, the elevator 10 includes a door opening control unit 11, a door opening time measurement unit 12, a door opening time determination unit 13, a storage unit 14, and a communication unit 15. The door opening time determination unit 13 and the storage unit 14 are connected to the communication unit 15. The door opening control unit 11 and the door opening time determination unit 13 are also connected to the storage unit 14. The door opening time measurement unit 12 is connected to the door opening time determination unit 13.

[0013] The door opening control unit 11 controls the opening and closing of the elevator door 10 based on the door opening time setting value 14a stored in the storage unit 14.

[0014] The door opening time measurement unit 12 has a sensor operating unit 16. The sensor operating unit 16 is composed of, for example, an infrared sensor, and detects when a passenger passes through the elevator door 10 each time the door opens. The door opening time measurement unit 12 then measures the door opening time each time the door opens based on the detection result of the sensor operating unit 16, and outputs the measured door opening time to the door opening time determination unit 13.

[0015] The door opening time determination unit 13 determines whether the door opening time set value 14a is appropriate based on the door opening time measured by the door opening time measurement unit 12 each time the door is opened and the door opening time set value 14a stored in the storage unit 14. The door opening time set value 14a is a value preset in the elevator 10 via the remote control server 30 and the remote control terminal 20 by the screen display terminal 40. When the door opening time determination unit 13 determines that the door opening time set value 14a is inappropriate, it outputs an appropriate door opening time as a door opening time recommended value to the communication unit 15 based on the door opening time measured by the door opening time measurement unit 12 and the door opening time set value 14a. That is, the elevator 10 having the door opening time determination unit 13 can output the door opening time recommended value selected based on the door opening time measured each time the door is opened and the preset door opening time set value 14a to the remote control terminal 20.

[0016] As an appropriate door opening time (door opening time recommended value), for example, when the measured door opening time is 3 seconds and the door opening time set value 14a is 7 seconds, 4 seconds or 5 seconds is assumed. Also, for example, when the measured door opening time is 6 seconds and the door opening time set value 14a is 4 seconds, the appropriate door opening time is set to 7 seconds or 8 seconds. Note that the door opening time recommended value calculated based on the measured door opening time and the door opening time set value 14a may be different depending on the algorithm for calculating the door opening time recommended value.

[0017] The storage unit 14 stores the door opening time set value 22a acquired from the remote control terminal 20 by the communication unit 15 as the door opening time set value 14a.

[0018] The communication unit 15 acquires the door opening time set value 22a from the remote control terminal 20 via the communication line 50 and outputs it to the storage unit 14. Also, the communication unit 15 transmits the door opening time recommended value output by the door opening time determination unit 13 to the remote control terminal 20 via the communication line 50.

[0019] The remote control terminal 20 is a terminal for remotely controlling the operation of the elevator 10. As shown in FIG. 1, it includes a communication unit 21, a storage unit 22, and a monitoring control unit 23. The remote control terminal 20 controls, for example, the door opening operation of the elevator 10 based on the door opening time set value 22a. Each of the storage unit 22 and the monitoring control unit 23 is connected to the communication unit 21. Also, the monitoring control unit 23 is connected to the storage unit 22.

[0020] The communication unit 21 receives the recommended door opening time value from the elevator 10 via the communication line 50, and receives the door opening time set value 32a set by the user from the remote control server 30 via the communication line 60. Also, the communication unit 21 transmits the recommended door opening time value received from the elevator 10 to the remote control server 30 via the communication line 60. Further, the communication unit 21 outputs the door opening time set value 32a received from the remote control server 30 and the recommended door opening time value received from the elevator 10 to the storage unit 22.

[0021] The storage unit 22 stores the door opening time set value 32a output from the communication unit 21 as the door opening time set value 22a, and stores the recommended door opening time value output from the communication unit 21 as the recommended door opening time value 22b. In addition to the door opening time set value 22a and the recommended door opening time value 22b, the storage unit 22 also stores various types of data (not shown) used by the monitoring control unit 23 to control the elevator 10.

[0022] The monitoring control unit 23 outputs various instruction data for controlling the elevator 10 to the elevator 10 via the communication unit 21 and the communication line 50, and remotely controls and monitors various operations of the elevator 10.

[0023] The remote control server 30 includes, as shown in FIG. 1, a communication unit 31, a storage unit 32, a door opening time analysis unit 33, and a screen configuration unit 34. The communication unit 31 is connected to each of the storage unit 32 and the screen configuration unit 34. Also, the screen configuration unit 34 is connected to the door opening time analysis unit 33, and the door opening time analysis unit 33 is connected to the storage unit 32.

[0024] The communication unit 31 receives the door opening time setting value set by the user via the communication line 70 through the screen display terminal 40. The communication unit 31 also receives the recommended door opening time value 22b from the remote control terminal 20 via the communication line 60. The communication unit 31 also transmits the door opening time setting value 32a set by the user to the remote control terminal 20. The communication unit 31 also transmits the configuration information for each screen to be displayed on the screen display terminal 40, which is input from the screen configuration unit 34, to the screen display terminal 40. The communication unit 31 also outputs the door opening time setting value received from the screen display terminal 40 and the recommended door opening time value 22b received from the remote control terminal 20 to the storage unit 32.

[0025] The storage unit 32 stores the door open time setting value 32a, which is input from the screen display terminal 40 via the communication unit 31, as the door open time setting value 32a, and the door open time recommended value 22b, which is input from the remote control terminal 20 via the communication unit 31, as the door open time recommended value 32b, and stores the door open time setting value 32a and the door open time recommended value 32b in chronological order. The door open time recommended value 32b is a value selected by the elevator 10 based on the door open time measured by the elevator 10 and the door open time setting value 14a.

[0026] The door-open time analysis unit 33 (an example of an aggregation unit) obtains the door-open time setting value 32a and the door-open time recommended value 32b from the storage unit 32 within the time range specified by the user via the screen display terminal 40. The door-open time analysis unit 33 also aggregates the door-open time recommended value 32b at time intervals specified via the screen display terminal 40, based on the comparison result of comparing the door-open time setting value 32a and the door-open time recommended value 32b within the time range specified via the screen display terminal 40. The processing in the door-open time analysis unit 33, i.e., the aggregation process of the door-open time recommended value 32b, will be described in detail in Figure 7 below. The door-open time analysis unit 33 also outputs information regarding the recommended value to be set for the door-open time setting, generated in the aggregation process of the door-open time recommended value 32b, to the screen configuration unit 34.

[0027] The screen configuration unit 34 (an example of an output unit) outputs information regarding recommended values ​​that can be set as door open time settings for the elevator 10. At this time, the screen configuration unit 34 uses the door open time setting value 32a stored in the storage unit 32 and the information regarding recommended values ​​that can be set as door open time settings for the elevator 10, output from the door open time analysis unit 33, to generate configuration information for the elevator remote control main screen 200 (see Figure 2 below) and door open time setting screen 300 (see Figure 3 below) to be displayed on the screen display terminal 40. The screen configuration unit 34 also outputs the generated configuration information for the elevator remote control main screen 200 and door open time setting screen 300 to the communication unit 31.

[0028] The screen display terminal 40 is an example of a terminal device for users to remotely perform various settings and check operation information for the elevator 10, and is composed of a mobile terminal such as a smartphone or tablet. The screen display terminal 40 can set the door open time setting value for the elevator 10 via the remote control server 30 and the remote control terminal 20. The screen display terminal 40 also displays information regarding recommended values ​​to set for the door open time setting value output by the remote control server 30, for example, on the door open time setting screen 300 (see Figures 2 to 5 below). Furthermore, the user can set the door open time of the elevator 10 on the door open time setting screen 300 displayed on the screen display terminal 40. Note that the screen display terminal 40 is not limited to a mobile terminal and may be composed of a desktop computer, printer, etc.

[0029] [Example of the elevator remote control main screen display] Next, an example of the display of the door opening time setting screen shown on the screen display terminal 40 of the elevator control system 100 will be described. Figure 2 is a diagram showing an example of the display of the elevator remote control main screen 200 shown on the screen display terminal 40 of the elevator control system 100 according to this embodiment.

[0030] As shown in Figure 2, the elevator remote control main screen 200 has a button 201 for the "door open time setting screen". When the user presses the "door open time setting screen" button 201, the door open time setting screen 300 (see Figure 3 below) opens. Note that in Figure 2, only the components of the elevator remote control main screen 200 according to this embodiment are shown, and other components (e.g., operation buttons, etc.) and their descriptions are omitted.

[0031] [Example of the door opening time setting screen] Figure 3 shows an example of the display of the door open time setting screen 300 shown on the screen display terminal 40 of the elevator control system 100 according to this embodiment. As shown in Figure 3, the door open time setting screen 300 has a door open time analysis display unit 400 and a door open time setting display unit 500. The door open time analysis display unit 400 and the door open time setting display unit 500 are displayed in order from top to bottom on the door open time setting screen 300. The specific display contents of the door open time analysis display unit 400 and the door open time setting display unit 500 are shown in Figures 4 and 5, respectively.

[0032] [Example of display on the door opening time analysis display unit] Figure 4 shows an example of the display of the door opening time analysis display unit 400 on the door opening time setting screen 300 in the elevator control system 100 according to this embodiment. As shown in Figure 4, a time range setting unit 401 is provided in the upper right of the door opening time analysis display unit 400. A time interval setting unit 402 is provided directly below the time range setting unit 401. A door opening time analysis result display unit 403 is provided in the lower half of the door opening time analysis display unit 400.

[0033] The time range setting unit 401 allows the user to specify a "time range" for which they want to analyze door opening times. The time range setting unit 401 is provided with a pull-down list of "YYYY / MM / DD / HH / MM / SS" for specifying the start point of the "time range" and a pull-down list of "YYYY / MM / DD / HH / MM / SS" for specifying the end point of the "time range". However, the present invention is not limited to this, and the input method for the start and end points of the "time range" may be other input methods such as manual input. Also, instead of specifying the start and end points of the "time range", the user may specify the start point and length of the "time range".

[0034] The time interval setting unit 402 allows you to set the interval (unit) at which to analyze door opening times and output the analysis results when analyzing door opening times for the "time range" set in the time range setting unit 401. The time interval setting unit 402 has a setting unit for "time interval 1" and a setting unit for "time interval 2". The setting units for "time interval 1" and "time interval 2" may be composed of pull-down lists or text boxes that the user can manually input.

[0035] The "Time Interval 1" setting unit sets the first time interval, which is the first analysis unit, for the "Time Range" set in the Time Range Setting Unit 401. For example, if a user specifies the length of the "Time Range" as one week and wants to analyze the door opening time for one week divided into units of "one day," they set "Time Interval 1" (first time interval) to "one day." Therefore, the first time interval is a time unit smaller than the "Time Range." For example, if the length of the "Time Range" is set to one month, the first time interval can be set to a shorter period such as one week or one day. This first time interval is also the output time range of the analysis results of the Door Opening Time Analysis Result Display Unit 403 (e.g., 0:00 to 23:00), and the output time range of the current setting value and recommended value in the Door Opening Time Setting Display Unit 500 shown in Figures 5 and 6 below (e.g., 0:00 to 23:00).

[0036] The "Time Interval 2" setting unit sets a second time interval, which is a second analysis unit smaller than the set "Time Interval 1" (first time interval). For example, if the length of the "Time Interval 1" (first time interval) specified by the user is "1 day," and the user wants to divide the door opening time of "1 day" into units of "1 hour" for analysis, then "Time Interval 2" (second time interval) is set to "1 hour." Therefore, the second time interval is a smaller time unit than the first time interval. For example, if the first time interval is set to 1 week, the second time interval can be set to something shorter than 1 week, such as 1 day or 1 hour. Furthermore, this second time interval is the output interval of the analysis results of the door opening time analysis result display unit 403 (for example, every hour), and the output interval of the current set value and recommended value in the door opening time setting display unit 500 shown in Figures 5 and 6 below (for example, every hour).

[0037] The door opening time analysis result display unit 403 displays a bar graph showing the door opening time setting value 32a and the door opening time recommended value 32b. The horizontal axis of the bar graph shown in the door opening time analysis result display unit 403 represents time. This horizontal axis divides "time interval 1" (first time interval) into "time interval 2" (second time interval), and "time interval 1" is expressed in units of "time interval 2". The vertical axis of the bar graph shown in the door opening time analysis result display unit 403 represents the average value in seconds (s) of the door opening time setting value 32a and door opening time recommended value 32b, aggregated for each "time interval 2" (second time interval) for the "time range" set in the time range setting unit 401. In addition, the "door opening time setting value" is represented by a black bar, and the "door opening time recommended value" is represented by a gray bar.

[0038] Specifically, for example, the "time range" set in the time range setting unit 401 is from "October 1, 2022, 00:00:00" to "October 7, 2022, 23:59:59," that is, 7 days. The "time interval 1" set in the time interval setting unit 402 is "1 day," and the "time interval 2" is "1 hour." In this case, the door opening time setting value 32a and the door opening time recommendation value 32b set within the 7-day range from "October 1, 2022, 00:00:00" to "October 7, 2022, 23:59:59" are extracted from the storage unit 32 of the remote control server 30. Then, the extracted 7-day door opening time setting value 32a and door opening time recommendation value 32b are divided into 7 parts, each representing "1 day" (1st hour interval), by the door opening time analysis unit 33. The seven daily door-opening time settings 32a and recommended door-opening time values ​​32b are then aggregated by the door-opening time analysis unit 33 in units of "1 hour" (second hour interval), and the aggregated results (results every 24 hours) are displayed on the door-opening time analysis result display unit 403, as shown in Figure 4.

[0039] Furthermore, by setting a time range and a time interval including the first and second time intervals in the door opening time analysis display unit 400, and checking the bar graph displayed in the door opening time analysis result display unit 403, users can grasp the aggregated information of the door opening time setting value 32a and the recommended door opening time value 32b within the set time range. This makes it easier for users to decide whether to change the current door opening time setting value to the recommended door opening time value.

[0040] [Example of display on the door opening time setting display unit 1] Figure 5 shows an example of the display of the door opening time setting display unit 500 on the door opening time setting screen 300 in the elevator control system 100 according to this embodiment. As shown in Figure 5, the door opening time setting display unit 500 has a current setting value display unit 501 and a recommended value display unit 502. The current setting value display unit 501 and the recommended value display unit 502 are displayed in order from left to right in the door opening time setting display unit 500.

[0041] In the current setting value display unit 501, the first time interval selected in "Time Interval 1" in Figure 4 (for example, 1 day) is displayed in units of the second time interval selected in "Time Interval 2" (for example, 0:00 to 23:00 every hour), and the door opening time setting value 32a is displayed as the "current setting value" for the door opening time corresponding to each time unit. The recommended value display unit 502 displays the "recommended value" corresponding to each time unit displayed in the current setting value display unit 501. That is, the number of "recommended values" output (the number of "recommended values" displayed in the door opening time setting display unit 500) is the number obtained by dividing the first time interval by the second time interval. The "recommended value" displayed here is the output result of the door opening time recommendation value aggregation process described later (see Figure 7).

[0042] As shown in Figure 5, the recommended value display unit 502 does not display the recommended value corresponding to "3 o'clock". This is because, in the door opening time recommendation value aggregation process described later, if it is determined that the current setting value corresponding to "3 o'clock" is appropriate and does not need to be changed, the "recommended value" is not output. In other words, the recommended value display unit 502 does not display the recommended value corresponding to the current setting value that does not need to be changed.

[0043] Depending on the size of the display range of the door opening time setting display unit 500, it may not be possible to display all the values ​​shown in the currently set value display unit 501 and the recommended value display unit 502. In this case, only a certain range of values ​​may be displayed, and a scroll bar may be used to scroll through and display the values ​​within that range. Furthermore, this embodiment is not limited to this, and the recommended value display unit 502 may be displayed in any way that indicates that changing the door opening time setting is not recommended. For example, the display method shown in Figure 6 may be used.

[0044] [Example of display on the door opening time setting display unit 2] Figure 6 shows an example 2 of the display of the door opening time setting display unit 500 on the door opening time setting screen 300 in the elevator control system 100 according to this embodiment. As can be seen by comparing Figure 6 with Figure 5, in the recommended value display unit 502 of the door opening time setting display unit 500 shown in Figure 6, instead of displaying a display mode that does not show the recommended value corresponding to "3 o'clock", the message "Change is not recommended" is displayed.

[0045] The recommended values ​​shown in the recommended value display section 502 in Figures 5 and 6, and the information indicating that changing the door opening time setting is not recommended, are collectively referred to as "information regarding recommended values." This information regarding recommended values ​​makes it easy for users to decide whether or not to change the door opening time from the current setting.

[0046] [Aggregation of recommended door opening times] Next, the process for aggregating recommended door open time values ​​in the elevator control system 100 according to this embodiment will be described. Figure 7 is a flowchart showing the procedure for aggregating recommended door open time values ​​in the elevator control system 100 according to this embodiment. The process described below is performed by the door open time analysis unit 33 of the remote control server 30 and starts when the remote control server 30 receives the time range and time interval (see Figure 4) specified by the user from the screen display terminal 40.

[0047] First, the door opening time analysis unit 33 aggregates the door opening time setting value 32a and the door opening time recommendation value 32b within the time range specified by the user (step S101). In this process, the door opening time analysis unit 33 retrieves the door opening time setting value 32a and the door opening time recommendation value 32b stored in the storage unit 32 based on the time range specified by the user (for example, 7 days). The door opening time analysis unit 33 then divides the retrieved door opening time setting value 32a and door opening time recommendation value 32b into first time intervals (for example, 1 day), and aggregates the divided door opening time setting value 32a and door opening time recommendation value 32b in second time interval units (for example, 1 hour).

[0048] Next, the door opening time analysis unit 33 compares the door opening time setting value 32a and the door opening time recommended value 32b within the aggregated time range to determine whether the door opening time setting value 32a is shorter than the door opening time recommended value 32b by a time threshold or more (step S102). In this process, if the door opening time setting value 32a is shorter than the door opening time recommended value 32b, and the difference is greater than or equal to a certain time threshold, the process in step S102 is determined to be YES. On the other hand, if the door opening time setting value 32a is shorter than the door opening time recommended value 32b, and the difference is not greater than or equal to a time threshold, the process in step S102 is determined to be NO.

[0049] In step S102, if the door opening time analysis unit 33 determines that the door opening time setting value 32a is shorter than the recommended door opening time value 32b by a time threshold or more (in the case of a YES determination in step S102), it proceeds to step S103. In step S103, the door opening time analysis unit 33 adds "1" to the first count, which is the number of settings that shorten the door opening time. The first count is the number of door openings where the door opening time setting value 32a is shorter than the recommended door opening time value 32b by a time threshold or more, and its initial value is "0".

[0050] On the other hand, in the process of step S102, if the door opening time analysis unit 33 determines that the door opening time setting value 32a is not shorter than the recommended door opening time value 32b by a time threshold (in the case of a NO determination in step S102), the door opening time analysis unit 33 performs the process of step S104. In the process of step S104, the door opening time analysis unit 33 compares the door opening time setting value 32a and the recommended door opening time value 32b to determine whether the door opening time setting value 32a is longer than the recommended door opening time value 32b by a time threshold. If the door opening time setting value 32a is longer than the recommended door opening time value 32b, and the difference is greater than or equal to the time threshold, the process of step S104 is determined to be YES. On the other hand, if the door opening time setting value 32a is longer than the recommended door opening time value 32b, and the difference is not greater than or equal to the time threshold, the process of step S104 is determined to be NO.

[0051] In step S104, if the door opening time analysis unit 33 determines that the door opening time setting value 32a is longer than the recommended door opening time value 32b by a time threshold or more (if step S104 is determined to be YES), it proceeds to step S105. In step S105, the door opening time analysis unit 33 adds "1" to the second count, which is the number of settings that extend the door opening time. The second count is the number of door openings where the door opening time setting value 32a is longer than the recommended door opening time value 32b by a time threshold or more, and its initial value is "0".

[0052] On the other hand, in the process of step S104, if the door opening time analysis unit 33 determines that the door opening time setting value 32a is not longer than the recommended door opening time value 32b by a time threshold (if step S104 is determined to be NO), it performs the process of step S106. In the process of step S106, the door opening time analysis unit 33 adds "1" to the third number, which is the number of cases in which the door opening time setting remains unchanged. The third number is the number of door openings in which the door opening time setting value 32a is not longer than the recommended door opening time value 32b by a time threshold, AND the door opening time setting value 32a is not shorter than the recommended door opening time value 32b by a time threshold, and its initial value is "0".

[0053] After processing in step S103, step S105, or step S106, the door opening time analysis unit 33 determines whether all door openings within the specified time range have been aggregated (step S107). In this process, if the comparison between the door opening time setting value 32a and the recommended door opening time value 32b aggregated within the time range specified by the user has been completed, step S107 will result in a YES determination. On the other hand, if the comparison between the door opening time setting value 32a and the recommended door opening time value 32b aggregated within the time range specified by the user has not been completed, step S107 will result in a NO determination.

[0054] In step S107, if the door opening time analysis unit 33 determines that the total number of door openings within the specified time range has not been aggregated (i.e., step S107 is determined to be NO), it returns to step S102 and repeats the processes from steps S102 to S106.

[0055] On the other hand, in the process of step S107, if the door opening time analysis unit 33 determines that the aggregation of all door openings within the specified time range is complete (if step S107 is determined to be YES), it proceeds to the process of step S108. In the process of step S108, the door opening time analysis unit 33 determines whether the ratio of the number of cases where the door opening time is shortened (first number) or the number of cases where the door opening time is extended (second number) to the total number is equal to or greater than the threshold number.

[0056] In step S108, if the door opening time analysis unit 33 determines that the proportion of the number of cases where the door opening time has been shortened (first case count) is equal to or greater than the case threshold, it aggregates the recommended door opening time values ​​32b for all cases where the door opening time setting value 32a is determined to be shorter than the recommended door opening time value 32b by a time threshold or more (step S109). In this process, the door opening time analysis unit 33 outputs the average value of the recommended door opening time values ​​32b corresponding to the first case, aggregated according to the time interval, to the screen configuration unit 34 as the recommended value to set for the door opening time setting value. The screen configuration unit 34 transmits the recommended door opening time value input from the door opening time analysis unit 33 to the screen display terminal 40 via the communication unit 31 for display.

[0057] Furthermore, in the process of step S108, if the door-open time analysis unit 33 determines that the proportion of the number of cases where the door-open time is extended (second number) is equal to or greater than the number threshold, it aggregates the recommended door-open time values ​​32b for all cases where the door-open time setting value 32a is determined to be longer than the recommended door-open time value 32b by a time threshold or more (step S110). In this process, the door-open time analysis unit 33 outputs the average value of the recommended door-open time values ​​32b corresponding to the second number, aggregated according to the time interval, to the screen configuration unit 34 as a recommended value to set as the door-open time setting value. The screen configuration unit 34 transmits the recommended door-open time input from the door-open time analysis unit 33 to the screen display terminal 40 via the communication unit 31 for display.

[0058] Furthermore, in the process of step S108, if the door-open time analysis unit 33 determines that both the ratio of the first number to the total number and the ratio of the second number to the total number are below the number threshold, it does not output a recommended value to set for the door-open time setting corresponding to the third number (step S111). In this process, the door-open time analysis unit 33 may output information to the screen configuration unit 34 indicating that it does not recommend changing the door-open time setting corresponding to the third number. Note that if the door-open time analysis unit 33 does not input a recommended value, the screen configuration unit 34 will not display the recommended value (see Figure 5). Also, if the door-open time analysis unit 33 inputs information indicating that it does not recommend changing the door-open time setting, the screen configuration unit 34 may display information indicating that it does not recommend changing the door-open time setting (see Figure 6).

[0059] After processing in step S109, step S110, or step S111, the process of aggregating the recommended door opening time value is completed.

[0060] [effect] As described above, in the elevator control system 100 according to this embodiment, the door open time analysis unit 33 aggregates the number of door openings that require shortening (first number) and the number of door openings that require extending (second number) for all door openings within the time range specified by the user. The door open time analysis unit 33 also determines whether or not to output a recommended value to be set for the door open time setting to the screen display terminal 40 based on the ratio of each of the first number and the second number to all door openings. The door open time analysis unit 33 also aggregates the recommended door open time value 32b according to the time interval specified by the user and outputs the recommended value for display on the screen display terminal 40. Furthermore, if the door open time analysis unit 33 determines that the door open time setting value 32a does not need to be changed (when both the ratio of the first number and the ratio of the second number are below the threshold), it either does not display the recommended value on the screen display terminal 40 or displays information indicating that a change is not recommended. Therefore, the elevator control system 100 according to this embodiment can aggregate and output recommended door opening time values ​​within a time range specified by the user, eliminating the need to check the generated recommended door opening time value each time the door opens and change the door opening time setting value.

[0061] It should be noted that the present invention is not limited to the embodiments described above, and various other applications and modifications can be taken as long as they do not deviate from the gist of the present invention as described in the claims. For example, the embodiments described above are detailed and specific explanations of the configuration of an elevator control system in order to clearly illustrate the present invention, and are not necessarily limited to those comprising all the configurations described. Furthermore, it is possible to replace some of the configurations of the embodiments described here with those of other embodiments, and it is also possible to add configurations from other embodiments to the configuration of one embodiment. In addition, it is possible to add, delete, or replace some of the configurations of the embodiments with those of other embodiments. Furthermore, the control lines and information lines shown are those deemed necessary for explanatory purposes, and not all control lines and information lines are necessarily shown in the actual product. In reality, it is safe to assume that almost all components are interconnected.

[0062] In the embodiment described above, the door opening time setting display unit 500 of the door opening time setting screen 300 displayed on the screen display terminal 40 displays only one "recommended value" corresponding to the "current setting value" of the door opening time, but the present invention is not limited to this. For example, in order to make it easier for the user to determine the door opening time setting value, the "recommended value" corresponding to the "current setting value" of the door opening time may be information indicating a range of "recommended values" rather than a predetermined numerical value. For example, instead of the recommended value "3.0" corresponding to the current setting value "5.0" at 3 o'clock shown in Figure 5, "0.2 to 0.4" indicating a range of "recommended values" may be displayed, and the user may be able to select a recommended value within the displayed range.
