Description

The present invention relates to an elevator control system that controls a holding time in the ascending / descending direction of a car in an elevator.

Generally, in an elevator, when a car responds to a landing call, the car stops while maintaining the ascending / descending direction registered in the landing call. The car stopped in this way is in a state in which a car call from the stop floor to the floor located in the ascending / descending direction of the car can be registered, and the elevating direction is maintained in this state until a predetermined time elapses. In such a car, if the car call is not registered even after a predetermined time has passed, after confirming that there is no landing call to respond to the floor located in the ascending / descending direction of the car from the stop floor, the car is moved in the ascending / descending direction. Ends holding and shifts to a state where it can answer another landing call.

As the time for holding the ascending / descending direction in this way, for example, a specific value according to the usage status of the elevator is uniformly set. Specifically, in an elevator where the number of users is large and it takes time to get on and off the car, the car goes up and down to prevent the car from answering another landing call before the user registers the car call. A long time is uniformly set as the time to hold the direction.

However, if a long time is uniformly set as the time to hold the ascending / descending direction, if no one gets into the stopped car in response to the landing call, for example, the user who registered the landing call arrives at the car. Even if you leave the landing without waiting, the car will have to wait for the registration of the car call for a wasteful time, so it will take time to move to a state where you can answer another landing call. There is.

On the other hand, if a short time is uniformly set as the time to hold the elevating direction, for example, when there are many elevator users and it takes time to get on and off the car, the car call is registered within this holding time. There is a risk that a new landing call will be assigned to the car and the car will travel in the opposite direction to the floor on which the user wants to go.

Conventionally, a control system has been proposed in which the time for holding the car in the ascending / descending direction is set longer according to a predetermined condition (see Patent Document 1). In this control system, when a landing call in the direction opposite to the car elevating direction is registered in the car stopped in response to the final car call, the holding time in the normal car elevating direction is not performed without performing the double door operation. It is decided to change the elevating direction of the car after keeping the door fully open while holding the elevating direction of the car for a longer time.

By the way, in a car that has stopped in response to a landing call, it may take a long time to register a new car call, but there are also situations where it is not. In the above control system, when the predetermined conditions are met, the operation efficiency is improved by not performing the double door operation. However, if the double door operation is not performed, the operation is appropriate according to the usage status of the elevator. It was difficult to improve efficiency.

It functionally has a timer unit 356 that holds the current time (see FIG. 3). Similar to the operation control device 4, the car control device 35 is, for example, a CPU, a non-volatile storage element such as a ROM or an EEPROM that stores various programs executed by the CPU and data necessary for the execution in advance. It is composed of a board, a microcomputer, or the like provided with a volatile storage element such as RAM, which is a so-called working memory of the CPU, and peripheral circuits thereof.

The car control unit 355 of the present embodiment controls the opening / closing operation of the car door 32 in the car 3 and controls for raising and lowering the car 3.

The timer unit 356 measures the current time like a clock and holds information about the current time (current time information). Based on the result of this measurement, the timer unit 356 of the present embodiment provides current time information such as current date information which is information about the current date, current day information which is information about the current day, and information about the current time. It holds a certain current time information and current time zone information which is information about a current time zone (for example, a time zone obtained by dividing 24 hours of a day into 12).

Specifically, in the current date information, a 4-digit number indicates the date. In the current day of the week information, a single digit number indicates the current day of the week, for example, "0" indicates Monday, "1" indicates Tuesday, "2" indicates Wednesday, "3" indicates Thursday, and so on. "4" indicates Friday, "5" indicates Saturday, and "6" indicates Sunday. In the current time information, a 4-digit numerical value indicates the current 24-hour display time. In the current time zone information, a two-digit numerical value indicates the current time zone, for example, "00" is from 0:00 to 2:00, "01" is from 2:00 to 4:00, and "02" is from 4:00 to 6:00. "03" is from 6:00 to 8:00, "04" is from 8:00 to 10:00, "05" is from 10:00 to 12:00, "06" is from 12:00 to 14:00, "07" is from 14:00 to 16:00, "08" indicates 16:00 to 18:00, "09" indicates 18:00 to 20:00, "10" indicates 20:00 to 22:00, and "11" indicates 22:00 to 24:00. In the elapsed time TM, a two-digit numerical value indicates time, for example, "10" indicates 10 seconds.

Further, the timer unit 356 of the present embodiment holds the elapsed time TM from the start operation to the stop operation by the update unit 353 described later, or the elapsed time TM from the start operation to the present. It is possible. The timer unit 356 sets the current week number information, which is information on the current number of weeks (for example, the cumulative number of weeks in one year), the current month information indicating the current date in months, and the current date as the current time information. It may be possible to retain the current seasonal information indicated by the season.

The setting system 350 responds to at least one of the current time (eg, the current day of the week, the current time zone), the current stop floor of the car, and the ascending / descending direction of the car 3 registered by the landing call. , Includes a setting unit 351 that can set the holding time of the car 3 in the ascending / descending direction. The setting system 350 of the present embodiment includes a TBL storage unit 352 that stores "holding time information TBL regarding the holding time in the ascending / descending direction of the car 3".

Further, the setting system 350 of the present embodiment determines a predetermined condition regarding the car 3 when the car 3 is stopped in response to the landing call, and when the car 3 satisfies the predetermined condition, the car door 32 It includes an update unit 353 that updates information on the required registration time (registration required time information) required from the completion of door opening to the registration of the car call. Further, in the setting system 350 of the present embodiment, when the car 3 is stopped in response to the landing call, the time when the car 3 is stopped (for example, the day of the week when the car is stopped, the time zone when the car is stopped), and the stop floor of the car when the car is stopped. , And a data storage unit (first storage unit) 354 that stores at least one of the ascending / descending directions of the car 3 registered by the landing call at the time of stop and the registration required time information in association with each other.

The renewal unit 353 sets the registration upper limit time (for example, the time preset as the time from the completion of the door opening of the car door 32 to the start of closing the door) for the car 3 stopped by the landing call after the door opening of the car door 32 is completed. If the car call is registered by the time it elapses, the registration time required from the completion of opening the car door 32 to the registration of the car call is calculated based on the elapsed time TM that can be obtained from the timer unit 356. .. Further, when the update unit 353 calculates the registration required time, the "time at stop (for example, the day of the week at stop, the time zone at stop) and the car at stop" acquired from the operation control unit 40 and the timer unit 356. The data storage unit 354 stores all of the "elevation direction of the car 3 registered by the stop floor and the landing call at the time of stop" and the registration required time information in association with each other.

In addition, the update unit 353 of the present embodiment registers the registration upper limit time for the car 3 stopped by the landing call when the registration upper limit time elapses after the door opening of the car door 32 is completed and the car call is not registered. It is stored in the data storage unit 354 as the required time. Therefore, the upper limit of the registration required time stored in the data storage unit 354 by the update unit 353 is a preset upper limit registration time.

When the car 3 is stopped in response to the landing call, the data storage unit 354 states that "the time when the car is stopped (for example, the day of the week when the car is stopped, the time zone when the car is stopped), the stop floor of the car when the car is stopped, and the stop. All of the "elevating directions of the car 3 registered by the landing call at the time" and the registration time information are stored in association with each other. In the registration required time information, a two-digit number indicates the registration required time, for example, "10" indicates 10 seconds.

The data storage unit 354 of the present embodiment collectively stores such information in a format such as data [day of the week, time zone, stop floor, ascending / descending direction, registration required time]. In the data [day, time zone, stop floor, elevating direction, registration time], for example, the day is Monday, the time zone is from 10:00 to 12:00, the stop floor is the second floor, and the elevating direction. Is in the ascending direction and the registration time is 10 seconds, it is shown as data [0,05,2,1,10].

The setting unit 351 is a TBL storage unit 352 according to the current time (for example, the current day of the week, the current time zone), the stop floor of the current car, and the ascending / descending direction of the car 3 registered by the landing call. Stores "holding time information TBL in the ascending / descending direction of the car 3". The setting unit 351 of the present embodiment sets the registration time in the past predetermined period according to the current day of the week, the current time zone, the current stop floor of the car, and the elevating direction of the car 3 registered by the landing call. The longest registration time is stored in the TBL storage unit 352 as "holding time information TBL in the ascending / descending direction of the car 3".

Specifically, the setting unit 351 of the present embodiment extracts registration required time information for a certain period in the past (for example, from 4 weeks ago to the present) from the data storage unit 354. In addition, the setting unit 351 reads the first registration required time information from the extracted registration required time information, and the first registration required time information and the "day, time zone, stop floor" related to the first registration required time information. , Elevating direction ”corresponds to the holding time information TBL [day, time zone, stop floor, elevating direction]. If the first registration required time information is longer than the corresponding holding time information TBL [day of the week, time zone, stop floor, ascending / descending direction], the setting unit 351 sets the corresponding holding time information TBL [day of the week, time zone, stop floor]. Overwrite the first registration time information in [Floor, elevating direction]. If the first registration required time information is equal to or less than the corresponding holding time information TBL [day of the week, time zone, stop floor, ascending / descending direction], the setting unit 351 sets the holding time information TBL [day of the week, time zone, stop floor]. Floor, elevating direction] is not overwritten.

The setting unit 351 performs this comparison process for all the extracted registration required time information, and performs an overwrite process as necessary. As a result, the setting unit 351 stores the longest registration required time among the registration required times in the past fixed period in the TBL storage unit 352 as "holding time information TBL in the ascending / descending direction of the car 3".

In the holding time information TBL stored in the TBL storage unit 352, a two-digit number indicates the holding time, for example, "15" indicates 15 seconds. In the holding time information TBL [day of the week, time zone, stop floor, ascending / descending direction], for example, the day of the week is Wednesday, the time zone is from 18:00 to 20:00, the stop floor is the 5th floor, and the ascending / descending direction is. In the downward direction, the holding time information TBL [2, 09, 5, 2] is shown.

A series of processes by the above setting system 350 will be specifically described below.

First, the process by the update unit 353 will be described with reference to FIG. When the car 3 arrives at the landing 5, the update unit 353 determines whether or not the car 3 has stopped in response to the landing call (step S1).

When the car 3 stops in response to the landing call (step S1: Yes), the update unit 353 determines whether or not there is a car call in the stopped car 3 (step S2).

If there is no car call in the stopped car 3 (step S2: Yes), the process proceeds to the steps after step S3 described later. Specifically, first of all, the opening of the car door 32 is started, and the car door 32 is in the open state (fully open state). That is, the opening of the car door 32 is completed (step S3). Next, the update unit 353 starts the timer unit 356 (step S4) and determines whether or not the car call has been registered (step S5).

When a car call is registered in the car 3 (step S5: Yes), the update unit 353 performs a stop operation of the timer unit 356 (step S6), and on the floor where the car 3 is stopped from the operation control unit 40. The stop floor information regarding a certain stop floor and the ascending / descending direction information regarding the ascending / descending direction registered by the landing call are acquired (step S7), and the current date information, the current day of the week information, and the current time zone information are acquired from the timer unit 356. (Step S8). Further, the update unit 353 acquires the elapsed time TM from the timer unit 356 as the registration required time, and the registration required time information (elapsed time TM), the acquired stop floor information, the ascending / descending direction information, the current day information, and the current day. The data is updated and stored in the data storage unit 354 in association with the time zone information (step S9), and the process ends.

If the car call is not registered (step S5: No), the elapsed time TM from the start operation of the timer unit 356 to the present is acquired, and the elapsed time TM is the registration upper limit time (for example, the door of the car door 32 is opened). It is determined whether or not the time from the completion to the start of closing the door (a preset time) is exceeded (step S10).

If the elapsed time TM does not exceed the registration upper limit time (step S10: No), the determination as to whether or not the car call has been registered is repeated (step S5).

When the elapsed time TM exceeds the preset upper limit registration time (step S10: Yes), the update unit 353 performs a stop operation of the timer unit 356 (step S6), and the operation control unit 40 gives the stop floor information. , And, the ascending / descending direction information about the ascending / descending direction registered by the landing call is acquired (step S7), and the current date information, the current day of the week information, and the current time zone information are acquired from the timer unit 356 (step S8). The update unit 353 associates the acquired information with the elapsed time TM and stores the data [day of the week, time zone, floor, ascending / descending direction, registration required time] in the data storage unit 354 by updating it (step S9). ), End the process.

If the car 3 has not stopped in response to the landing call (step S1: No), or if there is a car call in the stopped car 3 (step S2: No), the processes of steps S3 to S10. The process ends without performing the above procedure, and the process proceeds to the normal process of the stopped car 3 such as the opening / closing operation of the car door 32.

Next, a process that is constantly executed by the setting unit 351 will be described with reference to FIG. The setting unit 351 extracts data [day of the week, time zone, stop floor, ascending / descending direction, registration required time] in the past fixed period (for example, from 4 weeks ago to the present) stored in the data storage unit 354 ( Step S21), it is determined whether or not the number of extracted data exceeds 0 (step S22).

If the number of extracted data exceeds 0 (step S22: Yes), 1 is set in the count number CNT (step S23), and whether or not the count number CNT exceeds the "number of extracted data". (Step S24).

When the count number CNT does not exceed the "number of extracted data" (step S24: No), the setting unit 351 sets the data [day, time zone, stop] in the order corresponding to the count number CNT from the extracted data. Floor, elevating direction, registration time required] (for example, the first data when the count number CNT = 1, the second data when the count number CNT = 2, that is, the CNTth data) is read (step S25). , Add 1 to the count number CNT (step S26). Further, the setting unit 351 acquires the holding time information TBL [day of the week, time zone, stop floor, ascending / descending direction] from the TBL storage unit 352, sets this in the set value (step S27), and reads the data [ It is determined whether or not the registration required time of [day of the week, time zone, stop floor, elevating direction, registration required time] exceeds the set value (step S28).

If the registration required time of the read data [day of the week, time zone, stop floor, elevating direction, registration required time] exceeds the set value (step S28: Yes), the registration required time of the read data is dealt with. The holding time information TBL [day of the week, time zone, stop floor, ascending / descending direction] is stored in the TBL storage unit 352 (step S29), and the process returns to the judgment of step S24 until the count number CNT exceeds the number of extracted data. , Steps S25 to S29 are repeated.

If the registration required time of the read data [day of the week, time zone, stop floor, ascending / descending direction, registration required time] does not exceed the set value (step S28: No), the process returns to the judgment of step S24 and counts. The processing of steps S25 to S29 is repeated until the number of CNTs exceeds the number of extracted data.

If the count number CNT exceeds the number of extracted data (step S24: Yes), the process ends as it is.

If the number of extracted data is 0 or less (step S22: No), the process ends as it is.

A process executed by the setting unit 351 of the present embodiment at predetermined predetermined periods (for example, weekly, monthly, etc.) set in advance will be described with reference to FIG. In this process, in addition to the process that is always executed by the setting unit 351, between the step of setting the count number CNT to 1 and the step of determining whether or not the count number exceeds the "number of extracted data". It differs from the process constantly executed by the setting unit 351 in that the step of resetting the holding time information TBL [day of the week, time zone, stop floor, ascending / descending direction] to the default value is performed.

The setting unit 351 extracts data [day of the week, time zone, stop floor, ascending / descending direction, registration required time] in the past fixed period (for example, from 4 weeks ago to the present) stored in the data storage unit 354 ( Step S31), it is determined whether or not the number of extracted data exceeds 0 (step S32).

If the number of extracted data exceeds 0 (step S32: Yes), the count number CNT is set to 1 (step S33), and the holding time information TBL [day of the week, time zone, stop floor, ascending / descending] Direction] is reset (step S34), and it is determined whether or not the count number CNT exceeds the “number of extracted data” (step S35).

If the count number CNT does not exceed the "number of extracted data" (step S35: No), the step is performed until the count number CNT exceeds the number of extracted data, as in steps S24 to S29 in FIG. The process of steps S35 to S40 is repeated. If the registration required time of the read data [day of the week, time zone, stop floor, ascending / descending direction, registration required time] does not exceed the set value (step S39: No), the process returns to the judgment of step S35 and counts. The processing of steps S35 to S40 is repeated until the number of CNTs exceeds the "number of extracted data".

If the count number CNT exceeds the number of extracted data (step S35: Yes), the process is terminated as it is. If the number of extracted data is 0 or less (step S32: No), the process ends as it is.

According to the above setting system 350, the holding time in the ascending / descending direction of the car 3 registered by the landing call is lengthened, for example, when the number of users of the car 3 is large, and shortened when the number of users of the car 3 is small. It can be controlled according to the usage status of the car 3 based on the current day of the week, the current time zone, the current stop floor of the car 3, and the ascending / descending direction of the car 3 registered by the landing call.

In the setting system 350 of the present embodiment, the past registration required time information is stored in the data storage unit (first storage unit) 354, and the holding time in the ascending / descending direction of the car 3 is based on the stored registration required time information. Therefore, the holding time in the ascending / descending direction of the car 3 is changed according to the length of time from the completion of opening the car door 32 in the past to the registration of the car call.

Further, in the setting system 350 of the present embodiment, the data storage unit (first storage unit) 354 is provided with information on the time required for registration in the past, such as the time at that time (for example, day and time zone), the stop floor of the car 3. Since the car 3 is stored in association with the ascending / descending direction of the car 3 registered by the landing call, the holding time of the car 3 is the day, time zone, the stop floor of the car 3, and the ascending / descending direction of the car 3 registered by the landing call. It will be changed in detail according to the usage status of the basket 3.

Further, in the setting system 350 of the present embodiment, the setting unit 351 sets the longest registration required time from the registration required time of the past fixed period stored in the data storage unit 354 to the current day, the current time zone, and the present. Since the holding time information TBL [day, time zone, stop floor, elevating direction] corresponding to the elevating direction of the car 3 registered by the stop floor and the landing call of the car is set, the past car 3 When it is predicted that it is necessary to wait for the registration of the car call based on the situation, the ascending / descending direction is maintained for a sufficiently long time in the car 3 stopped in response to the landing call.

In the setting system 350 of the present embodiment, since the setting unit 351 resets the holding time in the ascending / descending direction at predetermined intervals, the holding time is irregular to the usage situation of the car 3 (for example, the elevator 1 is installed). Even if it is set according to (when an event is held in the building), the holding time will be adjusted to the normal usage situation of the car 3 after a certain period of time. Further, since the holding time is automatically reset by the setting unit 351, it is not necessary for the maintenance worker or the like to manually reset the holding time, and the labor required for the maintenance of the elevator 1 is reduced.

It should be noted that the setting system of the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the gist of the present invention. For example, the configuration of one embodiment can be added to the configuration of another embodiment, and a part of the configuration of one embodiment can be replaced with the configuration of another embodiment. In addition, some of the configurations of certain embodiments can be deleted.

In the setting system 350 of the above embodiment, the holding time in the ascending / descending direction of the car 3 is set based on the registration required time information regarding the time required to register the car call, but the user can get on and off the car 3. It may be set based on information about the time required.

For example, the holding time in the ascending / descending direction of the car 3 may be set based on the information regarding the operation of opening the car door 32 by the user. In this case, the car 3 performs at least one of the first door opening operation in which the user presses the open button (door open button) 332 and the second door opening operation in which the user presses the safety shoe of the car door 32. It is conceivable to include a door opening operation detection unit for detecting. Further, when the car 3 is stopped in response to the landing call, the setting system 350 determines the time when the car 3 is stopped (for example, the day of the week when the car is stopped, the time zone when the car is stopped), the stop floor of the car 3 when the car is stopped, and the stop floor. , At least one of the elevating directions of the car 3 registered in the landing call at the time of stop, and at least one of the first door opening operation and the second door opening operation detected by the door opening operation detection unit of the car 3. It is conceivable to include a data storage unit (second storage unit) 354 that stores the door opening operation information indicating the presence / absence in association with the information.

At this time, the setting unit 351 corresponds to at least one of the current time (for example, the current day of the week, the current time zone), the stop floor of the current car, and the ascending / descending direction of the car registered by the landing call. It suffices if the door opening operation information to be performed is acquired from the data storage unit 354 and the holding time in the ascending / descending direction can be set based on the acquired door opening operation information. Specifically, when the setting unit 351 indicates that the door opening operation information has the first door opening operation or the second door opening operation in the past, the door opening operation information has the first door opening operation or the second door opening operation in the past. It is conceivable to set the holding time in the ascending / descending direction longer than when indicating that there is no opening operation.

In such a case, the data storage unit (second storage unit) 354 can display the past door opening operation information at the time at that time (for example, the day and time zone at that time), the stop floor of the car 3 at that time, and the time at that time. The holding time in the ascending / descending direction of the car 3 is stored in association with the elevating direction of the car 3 registered in the landing call, and the holding time in the ascending / descending direction of the car 3 is set based on the stored door opening operation information. The holding time in the ascending / descending direction of the car 3 is changed according to the past usage status of the car 3 (for example, whether or not the door is opened).

Further, for example, the holding time in the ascending / descending direction of the car 3 may be set based on the information regarding the user getting on / off the car 3. In this case, it is conceivable that the car 3 includes at least one of a photographing unit capable of photographing the user in the car 3 and a load detecting unit capable of detecting the load of the user in the car 3. The photographing unit is, for example, a surveillance camera provided in the car 3. The load detection unit is, for example, a load sensor.

Further, the setting system 350 determines when the car 3 is stopped in response to the landing call, the time when the car 3 is stopped (for example, the day when the car is stopped, the time zone when the car is stopped), the stop floor of the car 3 when the car is stopped, and the stop floor. , At least one of the elevating directions of the car 3 registered in the landing call at the time of stop, the image of the user in the car 3 taken by the photographing unit, and the image of the user in the car 3 detected by the load detecting unit. It is conceivable to include a data storage unit (third storage unit) 354 that stores the information on the required time for getting on and off the user, which is calculated based on at least one of the loads of the user, in association with the information on the required time for getting on and off the user. At this time, the setting unit 351 is set to at least one of the current time (for example, the current day and the current time zone), the stop floor of the current car 3, and the ascending / descending direction of the car 3 registered by the landing call. It may be possible to acquire the corresponding boarding / alighting time information from the data storage unit 354 and set the holding time in the ascending / descending direction based on the acquired boarding / alighting time information.

In such a case, the data storage unit (third storage unit) 354 has information on the time required for getting on and off in the past, such as the time at that time (for example, the day and time zone at that time), the stop floor of the car 3 at that time, and the time at that time. The image and load data of the user in the car 3 are stored together with the ascending / descending direction of the car 3 registered by the landing call, and the holding time of the ascending / descending direction of the car 3 is set based on the stored boarding / alighting time information. The holding time in the ascending / descending direction of the car 3 is changed according to the time required for the user of the car 3 to get on and off in the past, which can be determined by.

Further, for example, the holding time in the ascending / descending direction of the car 3 may be set based on the information regarding the number of users in the car 3. In this case, it is conceivable that the car 3 includes at least one of a photographing unit capable of photographing the user in the car 3 and a load detecting unit capable of detecting the load of the user in the car 3. The photographing unit is, for example, a surveillance camera provided in the car 3. The load detection unit is, for example, a load sensor.

Further, when the car 3 is stopped in response to the landing call, the setting system 350 determines the time when the car 3 is stopped (for example, the day when the car is stopped, the time zone when the car is stopped), the stop floor of the car 3 when the car is stopped, and the stop floor. , At least one of the elevating directions of the car 3 registered in the landing call at the time of stop, the image of the user in the car 3 taken by the photographing unit, and the image of the user in the car 3 detected by the load detecting unit. It is conceivable to include a data storage unit (fourth storage unit) 354 that stores the number of passengers in the car 3 calculated based on at least one of the user's loads in association with the number of passengers. At this time, the setting unit 351 is set to at least one of the current time (for example, the current day of the week, the current time zone), the stop floor of the current car 3, and the ascending / descending direction of the car 3 registered by the landing call. It may be possible to acquire the corresponding passenger number information from the data storage unit 354 and set the holding time in the ascending / descending direction based on the acquired passenger number information.

In such a case, the data storage unit (fourth storage unit) 354 has information on the number of passengers in the car 3 in the past, such as the time at that time (day and time zone at that time), the stop floor of the car at that time, and the time at that time. It is stored in association with the ascending / descending direction of the car registered in the landing call, and the holding time of the elevating direction of the car 3 is set based on the stored number of passengers information, so that it can be determined from the image and load data in the car 3. The holding time in the ascending / descending direction of the car 3 is changed according to the number of passengers in the car 3 in the past.

Further, in the setting system 350 of the above-described embodiment, the holding time in the ascending / descending direction of the car 3 is used as information on the registration time required for registering the car call and information on the time required for the user to get on and off the car 3. Although it was set based on the above, it may be set based on the information regarding the running state of the car 3.

For example, the holding time in the elevating direction of the car 3 may be set based on the information regarding the elevating direction of the car 3. In this case, the setting system 350 stops when the car 3 stopped in response to the landing call travels in the opposite direction to the elevating direction (the elevating direction held by the car 3 and the elevating direction registered in the landing call). The time of the hour (for example, the day of the stop, the time of the stop), the stop floor of the car at the stop, and at least one of the elevating directions of the car registered in the landing call at the stop, and the landing. It may include a data storage unit (fifth storage unit) 354 that stores the car 3 stopped in response to the call in association with the ascending / descending direction held at the time of stopping and the reverse running information indicating that the car 3 has traveled in the opposite direction. Conceivable. At this time, the setting unit 351 is set to at least one of the current time (for example, the current day of the week, the current time zone), the stop floor of the current car 3, and the ascending / descending direction of the car 3 registered by the landing call. The corresponding reverse run information may be acquired from the data storage unit 354, and the holding time in the ascending / descending direction may be set based on the acquired reverse run information.

In such a case, the data storage unit (fifth storage unit) 354 shows the past reverse run information at the time at that time (for example, the day and time zone at that time), the stop floor of the car 3 at that time, and the landing at that time. The car 3 is stored together with the elevating direction of the car 3 registered by the call, and the holding time of the elevating direction of the car 3 is set based on the stored information. Therefore, the car 3 stopped in response to the landing call is called at the landing. The holding time of the car 3 in the elevating direction is changed depending on whether or not it is predicted that the car 3 travels in the direction opposite to the registered elevating direction.

Further, in addition to such a configuration, when the car 3 stopped in response to the landing call travels in the direction opposite to the ascending / descending direction, for example, the car 3 is used to confirm that there is a user in the car 3. , A photographing unit capable of photographing an image indicating that a user is present in the car 3 may be provided. The photographing unit is, for example, a surveillance camera provided in the car 3. In this case, the data storage unit (fifth storage unit) 354 travels in the direction opposite to the elevating direction held by the stopped car 3 in response to the landing call, and the user is inside the car 3. When it was confirmed that the car was stopped, the time when the car was stopped (for example, the day of the week when the car was stopped, the time zone when the car was stopped), the stop floor of the car when the car was stopped, and the car registered by calling the landing when the car was stopped. At least one of the elevating directions of the car may be stored in association with the reverse running information indicating that the car 3 stopped in response to the landing call has traveled in the direction opposite to the elevating direction.

The holding time of the car 3 in the ascending / descending direction includes information on the time required for registration regarding the time required for registering the car call, information on the operation of opening the car door 32 by the user, and the user getting on and off the car 3. The information may be set based on a plurality of information among the information regarding the information, the information regarding the number of users in the car 3, and the information regarding the traveling direction of the car 3. For example, as the holding time in the ascending / descending direction of the car 3, the longest time among the registration required time for a certain period in the past stored in the data storage unit 354 and the holding time set when the door is opened. It may be set.

Further, as the holding time in the ascending / descending direction of the car 3, in addition to setting a value based on such information, a predetermined specific value may be set. For example, the holding time in the ascending / descending direction of the car 3 may be set to a longer time than usual only on the lobby floor, which is considered to have many users of the car 3. When the building in which the elevator 1 is installed is an office building, a long time may be set as the holding time in the ascending / descending direction of the car 3 on weekdays and a short time may be set on holidays. When a specific value is set as the holding time in the ascending / descending direction of the car 3, for example, it may be set by a maintenance worker or the like.

As the holding time in the ascending / descending direction of the car 3 in one elevator 1, both the holding time set by the setting unit 351 based on various information and the specific value set by the maintenance worker or the like can be set. It may be. For example, when a large load is transported between predetermined floors where the car 3 can be stopped, the normal holding time is set as the holding time in the ascending / descending direction of the car 3 for the time zone and the floor where the transportation occurs. A longer specific value may be set, and the holding time in the ascending / descending direction of the car 3 may be set by the setting unit 351 based on various information for another time zone or another floor.

Although the setting unit 351 of the above embodiment executes the process (see FIG. 6) including the step of resetting the holding time information TBL at regular intervals, this process may be executed at another timing. For example, when the building in which the elevator 1 is installed is a commercial facility or an office building, in addition to executing the process including the step of resetting the holding time information TBL at regular intervals, or at regular intervals. It may be executed when the tenant of the building is replaced, etc., instead of executing the above. That is, instead of resetting all of the holding time information TBL to the default value, it may be reset to the default value for each day of the week, for each time zone, for each stop floor, for each ascending / descending direction, or a combination thereof.

Even if the setting unit 351 performs a process (see FIG. 6) including a step of resetting the holding time information TBL, a maintenance worker or the like performs a process of resetting the holding time information TBL at a specific timing. Good.

Further, the setting unit 351 of the above embodiment corresponds to the current time (for example, the current day and the current time zone), the stop floor of the current car, and the ascending / descending direction of the car 3 registered by the landing call. As the holding time information TBL [day, time zone, stop floor, ascending / descending direction], the longest registration required time is set from the registration required time in the past fixed period stored in the data storage unit 354. Alternatively, as the holding time information TBL [day, time zone, stop floor, ascending / descending direction], the average value of the registration required time for a certain period in the past stored in the data storage unit 354 may be set. Specifically, the setting unit 351 extracts a registration time longer than the threshold value from the registration time required for a certain period in the past stored in the data storage unit 354, and sets an average value of the extracted registration time. Good. In this case, the operation efficiency of the car can be improved while controlling according to the usage status of the car 3.

Further, the setting unit 351 of the above embodiment responds to all of the current time (for example, the current day of the week, the current time zone), the stop floor of the current car 3, and the ascending / descending direction registered by the landing call. It was possible to set the holding time in the ascending / descending direction, but the current time (for example, the current day of the week, the current time zone), the stop floor of the current car 3, and the ascending / descending direction registered by the landing call. The holding time in the ascending / descending direction may be set according to at least one of them. For example, when the same holding time is set on all floors where the car 3 can be stopped, the setting unit 351 is registered by the current time (for example, the current day of the week and the current time zone) and the landing call. It suffices if the holding time in the ascending / descending direction can be set according to the elevating direction. In this case, the TBL storage unit 352 stores the holding time information TBL [day of the week, time zone, ascending / descending direction], and the data storage unit 354 stores the stop time (day of the week at the stop, time zone at the stop) and The ascending / descending direction registered by the landing call and the registration required time information may be associated and stored.

The setting unit 351 of the above embodiment uses the current day of the week and the time zone as the current time, but the current day of the week, the current time zone, the current date, the current time, the current number of weeks, At least one of the current month, the current season, etc. may be used. The same applies to the stop time as stored in the data storage unit 354.

Although the setting system 350 of the above embodiment controls one elevator 1, it may control a plurality of elevators 1 each including a car 3. When the setting system 350 controls a plurality of elevators 1, it is conceivable that the update unit 353 updates the data for each car 3. Further, in this case, it is conceivable that the data storage unit 354 collectively stores the data (for example, registration required time information) updated by the update unit 353. In such a case, one setting system 350 aggregates the data (for example, registration required time information) updated by the update unit 353 for each car 3 for the elevators 1 of a plurality of units, and registers the car call. It is effective according to the usage situation of the car 3 by making a prediction by reflecting the tendency of the length of time required until the car 3 in a plurality of cars 3 and setting the holding time in the ascending / descending direction of the car 3 according to this prediction. Control can be performed.

The setting unit 351 and the TBL storage unit 352, the update unit 353, and the data storage unit 354 of the above embodiment are all provided in the car 3, but at least one of them is provided in a vehicle other than the car 3. May be good. For example, at least one of the setting unit 351 and the TBL storage unit 352, the update unit 353, and the data storage unit 354 may be provided in the operation control device 4. Further, at least a plurality of the setting unit 351 and the TBL storage unit 352, the update unit 353, and the data storage unit 354 may be integrated. For example, the setting unit 351 and the update unit 353 may be integrated, or the TBL may be integrated. The storage unit 352 and the data storage unit 354 may be integrated.

When the setting system 350 controls a plurality of elevators 1, the operation control unit 40 may perform operation management (so-called group management) in which landing calls are assigned to the plurality of cars 3. In the operation management by group management, when a landing call is made at a landing on a predetermined floor, a car 3 corresponding to the landing call is selected from a plurality of cars 3 so as to increase the transportation efficiency of the user. , The selected car 3 heads for the landing 5 containing the landing call.

Further, although the elevator 1 of the above embodiment is provided with one car 3, the elevator 1 may be provided with a plurality of cars 3.
