[0005]

However, the above-mentioned prior art has a drawback in that it is impossible to measure the number of waiting passengers in each direction even if a waiting passenger sensor is provided at each landing. Also, the hall call duration is treated as a waiting time, but if there are multiple waiters on one floor, the person who first registered the hall call and the person who later came to the elevator hall and waited It cannot be said that each user is seeking the correct waiting time due to the different waiting times. In addition, the method of selecting the driving program according to the traffic demand has a problem that the appropriate program cannot be selected only by the detection result of the traffic demand when the number of operating vehicles changes.

The present invention aims to improve the service performance of an elevator by calculating an average waiting time for each user, thereby performing an appropriate performance evaluation and selecting or notifying an operating program. Is.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to an embodiment shown in FIGS.

FIG. 1 is a flow chart for explaining the processing operation of the group management control device of one embodiment of the present invention, and FIG. 2 is a control block diagram of the elevator group management system of the present invention.

First, when the process is started by turning on the power or by restarting, an initial process such as clearing of the data table is executed in step S01. Next, the input / output processing of the hall call in both directions on all floors is performed in step S02. In step S03, communication with the number control devices C1 to Cn that control the operation of the elevator is performed by the communication control unit 111.
Via the transmission line L1 to transmit at least a control command for response to a hall call and receive an elevator status signal. Based on the received status signal, learning control such as the number of people getting off and the time required for getting on and off is performed in step S04. Also,
Here, learning such as whether or not there are unloaded items due to full capacity, measuring the duration of hall calls, and counting the number of hall calls is also conducted.
The average waiting time is calculated in step S05 based on the learning data. Next, an operation program is selected or control parameters are created based on the calculated average waiting time in step S06. Step S based on the operation program
At 07, hall call allocation processing, skip service for selectively servicing arbitrary floors, flexible zoning operation consisting of divided express, and operation management mode selection processing such as distributed operation are performed. In step S08, guidance notification processing is performed by the hall guidance device 115 according to the operation program created in step S06, the hall call allocation result in step S07, and the operation management mode. Finally, in step S09, other processes necessary for elevator control (simultaneous parallel running prevention, fault car rescue operation, insufficient function, abnormality detection of each elevator, etc.) are executed.

In FIG. 2, reference numeral 102 denotes passenger detection means, and 1
Reference numeral 03 is a passenger number measuring means, which measures the number of passengers for each floor and direction. As a concrete method,
There is a weighing device under the basket. However, since the accuracy is not sufficient with the commonly used weighing device, a photoelectric device is installed on the door, correction is performed by the number of registered car calls, counting by ultrasonic sensor or infrared sensor, or general camera etc. It is conceivable to use various passenger detection devices, such as image processing of the image of FIG. 1 to detect the number of passengers. In addition, when there is a passenger who is not able to get on board due to being full or the like, the unshipped product detection unit 104 detects unshipped product. The simplest method of detecting the unremaining load is to make a judgment based on the generation of a new hall call and the number of passengers in the departure car during or immediately after the departure. Further, when it is determined that there is an unloaded item due to the occurrence of full capacity, the last call duration time with the number of passengers is stored for use as a part of the unloaded item and waiting time.

The hall call number counting means 106 counts the number of hall calls for each floor and direction based on the call signal registered by the hall call registration device 105. Further, the hall call duration measuring means 107 measures the time from when the hall call is registered until the elevator completes the service and resets the hall call for each floor and direction. The average waiting time calculation means 108 counts the number of passengers by direction from the hall on each floor in the predetermined period by the number-of-passengers measurement means 103, the presence / absence of unladen weight detected by the unladen weight detection means 104 within the same period, and the unloaded time (loading time). The remaining waiting time of the user), the number of hall calls by each floor counted by the hall call number counting means 106 in the same period, and the respective data of the calculation results of the hall call duration measuring means 107 in the same period, The average waiting time for each floor and direction is calculated using the equation below.

The operation program selection or control parameter creation means 109 selects or creates an appropriate operation program based on the control target with operation schedule 112 based on the average waiting time calculated by the average waiting time calculation means 108. Using the created operation program, the operation control means 110 creates a control signal such as call assignment, and commands the elevator control devices C1 to Cn from the communication means 111 via the transmission line L1. For example, it is assumed that the energy-saving operation is set by the control target 112 with the operation schedule. In the past, in order to save energy, the number of operating vehicles was limited so that the duration of hall calls was within a prescribed value, but by setting this so that the average waiting time is within a prescribed time, excess or deficiency in transportation capacity Is more appropriately determined to prevent an excessive decrease in performance.

The guide mode selection means 113 selects the mode of guide notification to the hall based on the average waiting time calculated by the average waiting time calculating means 108, and the information guidance commanding means.
The information from the operation control means 110 is processed by 114, and the information is displayed to the waiting passengers by the hall guide notification means (for example, LED or liquid crystal, or a display display such as EL or plasma) 115 provided in each floor hall. For example, it is assumed that the divided express operation is set by the control target with an operation schedule 112 when the average waiting time on the lobby floor becomes long. Now, if the result of calculation by the average waiting time calculation means 108 indicates that a long wait has occurred on the lobby floor due to the unremaining load on the lobby floor or the extension of the lap time, the flexible zoning of the operation program is selected or the control parameter creation means 109 is used. Select a type of split express operation on the 5th floor. Thereby, the selected operation command is transmitted from the operation control means 110 to the machine control devices C1 to Cn via the transmission line L1. Hall guide notification means 115 at this time
The information guidance command to is also transmitted. FIG. 4 shows an example of the display by the hall guidance notifying means. Normally, as indicated by DP 403, a normal service status mode for displaying the car position, the traveling direction, the condition inside the car, etc. is selectively displayed. When the division express is carried out, the guidance mode selection means 113
First, select the mode to display the average waiting time on the general floor, and display the current average waiting time as shown in DP401.
Notify the customers (users) waiting in the hall that the waiting time will be long. On the lobby floor, as shown in DP402,
Select a stop floor display mode for split express and display the floors that the elevator can stop to service the car call. DP when service elevator is near
Switch to the normal service status guidance mode indicated by 403.

Next, an example of a method of calculating the average waiting time will be described.

First, the names of the variables used and their contents are shown below.

WTIM: Average waiting time in a predetermined period HCTIM (j, i): Average hall call duration time for each floor direction HCTIM2 (j, i): Previous hall call duration time when leftover detection is detected DRTIM: Door opening time PSNUM ( j, i): Number of passengers for each floor direction HCNUM (j, i): Number of hall call registrations for each floor direction STTIM: Stop time j: Direction i: Number of floors m: Number of hall call services Per passenger at a given time The approximate value of the average waiting time can be calculated by the following equation 1.

[0019]

[Equation 1]

The predetermined time in this case can be set in various ways, for example, every 5 minutes or every 100 passengers.

However, this formula is satisfied when all floors are used uniformly, and when passengers arrive at each landing at substantially uniform time intervals, the traffic for each floor is satisfied. If there is a difference in quantity, the errors may be large because they are averaged for each floor.

Therefore, the following is a formula considering such a problem.

[0023]

[Equation 2]

First, the product of the hall call duration, which is the denominator of Equation 2, and the number of passengers is obtained each time the hall call service is completed, and is cumulatively added. Also, the cumulative addition of the number of passengers, which is the numerator, is performed every time the hall call service is completed, and the former is divided by twice the latter every predetermined period (for example, m = 100 times).

As described above, by performing the processing every time the hall call service is completed, it is possible to eliminate the difference in traffic volume between floors and the disturbance such as mischief and reopening, and the average waiting time of each user. Can be obtained more accurately.

Further, even if the elevator responds to the hall call, if there is a remaining load due to being full, the hall call duration is recorded in HCTIM2, and it is calculated more accurately by the formula 3 at the time of the next service. Can be obtained.

[0027]

[Equation 3]

FIG. 3 shows a flow chart of an embodiment of calculating the average waiting time based on the same idea as the equation 2 or the equation 3.

The following processing is started at a constant cycle, for example, every 1 second. First, when a hall call is detected in step S301, a hall call present flag is set in step S302, and counting of the hall call duration is started in step S303. If the hall call is not detected in step S301, it is determined in step S304 whether or not the hall call service command recording flag is on. If not, the process proceeds to the next floor loop. If it is ON, the hall call registered up to now is reset, that is, the hall call service is completed, so the process proceeds to the next step S305, and this service command recording flag is reset. Next in step S306
Read the recorded value of the number of passengers of the Unit for which the service order was issued in. Next, in step S307, it is determined whether or not the vehicle was fully loaded last time, and if it was fully loaded, step S30
In step 8, the product of the hall call duration and the number of passengers in consideration of the previous hall call duration, which is the denominator of Equation 3, is added to the cumulative addition value S. If you have not fully booked the last time, step S
In 309, the product of the hall call duration and the number of passengers, which is the denominator of Formula 2, is added to the cumulative addition value S of the denominator. Step S
At 310, the number of passengers, which is the numerator of Formulas 2 and 3, is added to the cumulative addition value P of the numerator. Step S determines whether the elevator servicing the floor departs near full capacity
If it is determined in step 311 and the passenger departs when the vehicle is full, step S312
Hall call duration time HCT when left unloaded next time
Record the duration of this hall call in IM2. If it is not full, in step S313, the remaining uncalled hall call duration HCTIM2 is cleared. In step S314, it is determined whether or not the above processing has been performed for all floors in both directions, and the above processing is repeated until the completion of all floors in both directions. When all floors have finished in both directions, it is determined in step S315 whether or not the predetermined time has expired. When the predetermined time has expired, the average waiting time WMTIM of the predetermined time can be obtained by dividing the cumulative addition value S of the denominator by twice the cumulative addition value P of the numerator in step S316. At this time, the cumulative addition values P and S are cleared to 0.

With the above processing flow, if the average waiting time is calculated, the average waiting time can be calculated with extremely high precision. By selecting the operation program and creating the control parameters based on this calculation, the service performance can be improved. High group management control can be realized, and the convenience of the user can be improved by notifying by the guide device installed in each floor elevator hall based on the calculation result.

As another embodiment of the selection of the operation program in step S06 of FIG. 1, FIG. 5 shows an example of floor individualization control based on the average waiting time when the first floor is a lobby floor with seven floors. . The average waiting time is calculated for each floor direction, and the hall call allocation is performed by selecting the call allocation evaluation method according to the length. In FIG. 5, rule 1 is an allocation method that minimizes waiting time, rule 2 is a call allocation method that minimizes the maximum waiting time of the entire call, and rule 3 is a congestion degree priority that selects and allocates an empty elevator. Method, rule 4 is to allocate an empty car in consideration of the use of wagons, and rule 5 is to register multiple elevators on the same floor or additional call halls to allocate one elevator for each individual. Made possible,
Use the method of assigning calls to multiple units.

For example, if the average waiting time in the ascending direction of the lobby floor is short, for example, if it is 20 seconds or less, it is possible to call up a plurality of cars. Use the shortest allocation. If the average waiting time is not so long, for example, 30 seconds or less, the lobby floor is expected to be slightly congested, so the waiting time is assigned as the shortest waiting time, and the general floor is set as the maximum waiting time for the shortest waiting time and the lower direction is set as the lowering direction. Congestion priority is assigned. When the average waiting time is long, the waiting time shortest allocation is selected in the lobby floor and the general floor ascending direction, and the maximum waiting time shortest allocation is selected in the general floor descending direction.

Also, in the average waiting time for each floor direction,
More appropriate personalization can be performed by multiplying the number of passengers.

The selection of the allocation method is not only performed automatically, but also a possible allocation method is displayed on the hall guide device so that the passengers can select and input the allocation method at the time of call registration. It is possible.

Further, in the above, the allocation method is selected by the average waiting time for each hall call for each floor direction, but it may be uniformly selected by the average of all floors.

[0036]

As described above, by calculating the average waiting time of each hall waiting customer instead of the hall call duration, it is possible to perform an appropriate performance evaluation and select an operation program. Service performance can be improved.
