Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a reserved operation control device for an elevator, and more particularly to a reserved operation control device for an elevator that controls shortening of the pause operation start time of a car reserved and waiting at a destination floor. be.

[Prior art]

In recent years, with the rapid development of elevators, it has become possible to set various operation service modes. This operation service mode includes dispatching the car to the executive floor where the executive office is located, and dispatching the car to the main floor during dispatch, etc. An attendant issues a vehicle dispatch command by operating a mode switch installed in the vehicle.

However, the attendant must operate the hand switch accurately at the scheduled time, which is an extremely troublesome task.

In addition to this mode switch, there are many other switches such as a meeting room operation switch and a service disconnection switch, and it is extremely difficult to remember to operate these switches accurately at the scheduled time. In this case, the switch is automatically turned on at a predetermined time using a clock, or when the switch is scheduled to be switched on at the same time every day, such as when driving to work, etc., thereby eliminating the need for an operator to operate the switch.

However, there are cases where it is often necessary to change the time set on the clock, and there are also many requests to change the operating floor for main floors, assembly room operations, lunch hours, etc., so a more flexible elevator control system is desired. ing.

In contrast, by using currently popular personal computers and the like as input devices.

Regarding the dispatch of cars to important customer floors and floors expected to be crowded,
A system is being considered in which the number of cars to be allocated, waiting floor, time, etc. can be set and canceled as desired.

On the other hand, elevators are equipped with a parking device that saves energy by turning off the interior lights of cars that are left on standby for long periods of time because they do not respond to calls.

However, if the waiting car based on the reservation information is on standby with the door closed, the car will wait until the passenger appears on the waiting floor, and the person in charge of setting the reservation time will have to wait until the passenger appears on the waiting floor. The time is often unknown;
As a result, the time is often set with consideration for waiting delays. As a result.

Elevators come to rest after completing their normal downtime, resulting in energy wastage (problems).

[Summary of the invention]

Therefore, the present invention has been made to eliminate the above-mentioned drawbacks, and is designed to enter a pause operation earlier than the normal pause time for a car that is on standby based on reservation information for waiting with the door closed. An object of the present invention is to provide an elevator reservation operation control device that controls stop time to be short.

It selects the reservation information to be requested and outputs it as an operation control signal.

Reference numeral 5 denotes an elevator reservation door close/standby control unit which takes in the operation control signal supplied from the reservation operation control unit 3 and also receives the operation control signal based on the input information (landing call, in-car call, etc.) supplied from the elevator 6.・℃ A reserved door close standby command is issued to the elevator 6. On the other hand, the elevator 6 executes an operation based on the reserved door close standby command supplied from the elevator reserved door close standby control unit 5. 7 is a pause time change unit. °, the output information of the elevator 6 that operates according to instructions from the elevator reserved door close standby control unit 5 and the reserved door closed standby command issued from the elevator reserved door closed standby control unit 5 are input, and the pause time during reserved door closed standby is input. A shortened car will be held.

FIG. 2 is a system configuration diagram for explaining one embodiment of the elevator operation reservation control device according to the present invention. In the figure, reference numeral 10 denotes a car control device; in particular, only the car control device for one elevator is shown. The car control device 10 is operated by a central processing unit 11 and an interface 15 that receives information supplied from a transmission element 13, a memory 14, and an external device 16, which are connected to the central processing unit 11 via a data node 12. It is configured. Reference numeral 20 denotes a group control unit for efficient operation by controlling the operation of each elevator, and includes a central processing unit 21 and a transmission element 23 connected to the central processing unit 21 via a data bus 22. .24. It is composed of a memory 251, an interface 28 that takes in the signal of the hall call button 27, and a clock 29.

The transmission element 23 transmits information in parallel with the transmission element 13. Also, the clock 29 has an automatic calendar function, and automatically sets the date and time of the first month and second day of the calendar. 30 is a statistical device that statistically processes the operation status and service status of the elevator, and includes a central processing unit 31 and a transmission unit connected to the central processing unit 31 via a data bus 32. Element 33.3
4. It is composed of a memory 35. The transmission element 23 and the transmission element 24 transmit necessary information in parallel. 40 is a personal computer used as an input medium.

For example, Mitsubishi Electric's MULT116 is used.

The personal computer 4Q includes a central processing unit 41 and a transmission element 43 . connected to the central processing unit 41 via a data bus 42 . Memory 44. It is made up of Intern Aces 45-47. The transmission element 43 serially transmits necessary information between the transmission element 34 and the intern aces 45 to 47.
is a display device 50 as a peripheral device for the personal computer 40. Floppy disk device 60
and a keyboard 70, respectively.

In the apparatus configured as described above, after operating the personal computer 40, a staff member or the like operates the keyboard 70 to input the content of the desired reservation in a predetermined format. Of the input information and the corresponding information, only the necessary information is displayed on the display device 50.

On the other hand, the personal computer 40 reads the program stored in the floppy disk device 60,
This program is stored in the memory 44 provided inside the personal computer 40, and predetermined processing is executed according to this program. The reservation information input via the keyboard 70 is then supplied to the statistical device 30 via the transmission elements 43 and 34 and stored in the memory 35. In the statistical device 30, the central processing unit 31 operates according to the program stored in the memory 35 to read out the month, day, day of the week, and time of the day using the automatic calendar program, and based on these information, calculates the next date. Scan the reservation information stored in and select the corresponding reservation information. That is, scanning the reservation information retrieves the reservation information corresponding to the date 9 time when the date 2 time added to the reservation information is input. Next, the reservation contents of the retrieved reservation information are converted into a reservation operation control signal suitable for use by the first group management device 20 and the car control device 10 and output. This reserved operation control signal is then supplied from the transmission element 33 to the group management device 20 via the transmission element 24 and stored in the memory 25. Here, the fifth group management device 20 is one that is generally used,
According to the information on the hall call button 27, the most suitable car is selected and its allocation process is executed. The first group management device 20 immediately executes the given operation by constantly detecting the reserved operation control signal.

Here, the action that can be taken is dispatching a car.

A wide variety of options are possible, such as selecting a service pattern, changing the live floor, specifying or changing a specific floor (VIP floor, etc.), and specifying a service separation floor.

In this explanation, only the allocation of an arbitrary number of cars to an arbitrary floor will be explained. In other words, the first group management device 20 is the statistical device 3
The designated number of cars are selected and operated at the specified floor by the reservation operation control signal supplied from 0. Also,
The selected car is given a service command to the first floor and a command to close the door and wait. Then, this command is supplied from the transmission element 23 to the transmission element 131C.

The car control device 20 executes control for the selected car 9.

Then, the car waiting at the reserved floor outputs a stop command to the external device 161C and comes to rest earlier than the normal elevator stop due to the stop time shortening process.

FIG. 3(,) is an explanatory diagram of a reservation table handled in the personal computer shown in FIG. After being created, it is stored in the floppy disk device 60 via the interface 46. In this example, 00
It is possible to make 999 reservations from 1 to 999, and each reservation can be called "yr" (j = oot ~ 999) with the reservation table YTK Sanykus j. As shown in Figure (b), it is composed of θ to 15 columns in which reservation contents are entered in each column. Each column is configured to correspond to a 1-byte (8-bit) VC of the memory, and each column is filled with numbers or letters using ASCII code.

FIG. 4 shows a program stored in the floppy disk device 601C and transferred to the memory 44 of the personal computer 40 when executed, and shows a reservation input processing program at 1%. First, when the personal computer 40 operates, "YOYAKU?" is displayed on the display device 50 in step S1. Next, use the keyboard 70 to display “DYS”.
When inputting, step S, to step SXo
If the character "YES" is inputted, the process goes to step S, and if any other character is inputted, the process returns from step S3 to step S1. If the determination in step S is YES, the process moves to step S4 to display the reservation number.

Then, when the 3-digit reservation number is input, step Ss
After executing steps so#s, ls, a8G, the process returns to step S1. here.

Step S7 is a date and time input program, S is a floor input program m5ll is an input program for reservation cart columns 14 and 15, and these programs are, for example, shown in FIGS. 5(a), (b), (
As shown in c), each subprogram is prepared in advance.

On the other hand, when the process moves from step S to step 810, a reservation number display process is executed, and then from step 811 where the reservation number is input, the process returns to step SSO. Then, in step SXS, the input reservation number is set to j, and then the process moves to step 813. In step 813, the reservation details of the previously input reservation number are displayed on the display device 50, and the first "CNCL" is displayed.
When is input, the process proceeds to step SI6, where all the reservation details are cleared, and the process returns to step S, ending the process with only display.
(other than L", 10K"), the process returns to step SXS to display the reservation details.

5(a), (b), and (e) are subprograms used in the program shown in FIG. 4. For example, in step 7, "HIZUKE" is displayed on the display device 50. , when a 4-digit number is input from the keyboard 70, steps S,b to step S7
Transition to 0. Then, in step Sac, the numbers input into the date column are stored. Similarly, steps 5yd-8 and f represent the start time, step s'rg-87+ represents the end time, and step S'rg-87+ represents the end time.
The floor is input at ga to S 6c, the number of cars is input at steps 5ed-8 and t, and the designated car number is input at step Sag-8et.

FIG. 6 shows a program stored in the memory 35 of the statistical device 30, which creates a reservation operation control signal from the date and time read from the reservation table and automatic calendar transmitted from the personal computer 40. It is assumed that this program is one that is repeatedly processed once every minute, and reading of the day and time has already been read by another program. Then, in step S, a clearing process is executed to erase the previously created reservation operation control signal before it is created this time, and the process moves to step S. And step S,
In steps 810 to 810, the reservation table is scanned from 001 to 999 to create a reservation operation control signal. However, in step S4.

Determine whether the reservation content is not "0", and step S.
In this case, the date is determined and if all the dates are "0", it is assumed that the processing is to be performed every day and the process moves to step S7. Further, if the determination in step S is No, the process moves to step S6 to judge whether or not the date is the current day, and if it is not the current day, the process moves to step SIo, which will be described later. . Further, if the determination in step S6 is YES, step S? Then, the start time and end time are determined, and it is determined whether the reserved operation is to be selected only once. If it is not only once, the process moves to step S8 to determine whether the current time is included in the reservation time range, and if it is within the range, the jth reservation details (
12 to 15 columns) are converted into control signals in step S.

Further, if the determination in step S is YES, the process moves to step S0 only if the current time and the reserved time match. Note that if you select only one operation, the control signal will continue to be generated for one minute, and there is a risk that the operation may continue many times, but under normal conditions, the operation is completed in one minute. This kind of problem does not occur at all because it is never done. Then, in step S, a program for creating a reservation control signal for the j-th is called, and after this process is executed, step st
Execute the operation to return to o+ss.

Note that FIG. 7 is a subprogram of the scan reservation number update program shown in step S in FIG. In step S3, the specified number of cars with the door closed or on standby is cleared.In step S4, the process of clearing the number of cars designated as waiting with the door closed is executed for all floors.

FIG. 8 shows step S9 of the date and time chart shown in FIG.
This is a subprogram of the part indicated by , which creates a reservation operation control signal from the jth reservation contents. Then, in step S, a, the column 12 is placed on the scanning floor door.
, 13, the process moves to steps S, , gK. Then, in step Sol, after setting the designated number of closed-door waiting cars in column 14 on the m floor, the process moves to step Sob to determine whether there is a designated car. and,
If the judgments in steps S and h are YES, the process moves to the exit after executing the process of setting the designated car number of column 5 on the m floor in step Sgi.

Moreover, if the judgment in steps S and h is no,
Move straight to the exit.

Figure 9 shows the case where the number of units is specified as whether to wait with the door closed.

This is to check whether the number of cars allocated to a specified floor satisfies the specified number, and if it is not satisfied, a white signal is given by adding door closing to the busy allocation program. Then, the subprogram includes steps S□ to S, as shown in FIG.

In step S, m
Determine whether the specified number of vehicles exists on the floor.

Further, in step S4, it is determined whether the designated number of vehicles with the door closed satisfies the designated number of vehicles with the door closed.

In step S, an additional assignment signal for closing the door is generated.

In addition, in Fig. 9, YCDm is the designated number of units waiting to close the door to the m floor, ATCm is the additional assignment signal for closing the door to the m floor,
AKCm indicates the number of cars on the m floor with a door closing service command, and the door closing service command DCmn on the m floor is scanned for all cars, and the car with "1" is selected.

FIG. 10 shows an allocation program for nine door-closed standby services, and this program includes an additional allocation process when specifying the number of cars for one door-closed standby service and an allocation process for a designated car number. and.

In steps 88 to srs, all floors are scanned, and in steps 811→S, t-+S, assignment processing is executed for the presence of a designated car number, and in step S4, the presence or absence of a designated car number is determined. If there is a designated car, the process advances to step 811, where it is determined whether a command (assignment) for the designated car has already been issued. If not specified, step S1
! The process moves to step S8 to execute processing for determining that the designated car is selected and to determine that the designated car is the designated car. However, it goes without saying that the designated car command must be processed prior to the car number command.

Next, step 8. At this point, the selected car is given an assignment command for going up and down m floors and a door closing service command. However, if a landing call for going up or down to floor m is registered in step S8, step S1. Then, processing is executed to clear the door closing service command for the m floor for all cars. This is so that when a hall call for the mth floor is registered, the service can be immediately assigned and executed. Further, in step s, -8, it is determined whether or not a door closing additional assignment signal is issued in step S in response to an additional command for the specified number of cars, and in step S6, door closing service for the m floor is performed. The selection of the command is made and that basket is K.
Incorporated into AGA. The car selected in this way receives an allocation and door closing service command in step S, and furthermore, in step S, additional allocation is prohibited for the car to which the door closing service command has been given. However, the assignment process after 51C is prohibited so that the door can be placed on standby with the door closed on the designated floor. Note that the prohibition of additional allocation to a car for which there are no door closing service commands on all floors is immediately canceled after the processing of the flowchart shown in FIG. 1θ.

In FIG. 1O, ATCm is an additional assignment signal for closing the door to floor m, and AKUmn is an assignment command 1. for machine n ascending to floor m. A K D m n is an assignment command for machine n going down on floor m, DCmn is a door closing service command for machine n on floor m, N A S K n is an additional allocation prohibition signal for machine n, and YCKm is a standby for door closing on floor m. Each indicates the command car number.

FIG. 11 shows step S of the flowchart shown in FIG.
6 is a flowchart showing an example of a subprogram used in step 6, which is used to select a car to which a door closing service command is given.

In other words, the purpose is to select the car that is expected to be able to wait with the door closed on the mth floor as soon as possible, and to compare the car with the longest expected arrival time on the up and down trips for each car. The shortest one is selected, and the selection basket is first cleared in step 86m. Next, in step Seb, the expected arrival time of the selected car is set to the maximum value, and in step 56c=S6e, all the cars are scanned. In this case, in steps SI and e, it is determined whether additional allocation is prohibited for the nth machine, and in step S6t, it is determined whether the m floor is receiving door closing service, In step sag, the higher expected arrival time for the upstream and downstream is selected, and if the upstream is a dog, step S6h+Sa' is executed, and if the upstream is small, the process proceeds to step 86 and processes 861. and.

In steps S and h, it is determined whether or not the expected arrival time of the nth car on the m floor is smaller than the value of the previous car. Reset the value. And step Sah
+ This kind of operation in S61 is performed in step S6h+
The operation is similar to Sal.

FIG. 12 is a flowchart showing the operation for canceling the allocation command. In step S, initial setting is performed by setting the scanning car setting register n to zero, and then the process moves to step S. Add 1 to the set floor. Next, in step S, the car position floor is set as the scanning floor, and in step S4, it is determined whether or not there is a door closing service command for the car position floor. If the determination in step S4 is NO, then in step S, it is determined whether or not aircraft No. n is in ascending service, and if this determination is YES,
Proceeding to step S, it is determined whether or not the n-th car has started closing its door. If the determination in step S6 is YES, the process moves to step S, where the cancellation of the m-floor ascending assignment command for the n-th car is executed, and step S
.

In this step, it is determined whether the engineering scan has been executed for all machines, and if the answer is no, the process moves to step S and the same operation is repeated, and if the answer is yes, the series of operations ends. .

Further, if the determination in step S is NO, it is determined in step S whether or not the n car has started closing the door, and if the determination is NO, step S , and if yes, step 810
In step S8, after the m-th floor down assignment command for the n-th car is released, the process moves to step S8.

Furthermore, if the determination in step S4 is YES, it is determined in step 811 whether or not the car has stopped and is directionless (.If the determination is NO, step S811 is performed). The process moves to S8, and if the answer is YES, in step sty, the allocation command for going up and down the m floor of the nth car is canceled, and then the process goes to step S.In addition, the one-door closing service command is canceled. is performed by the process shown in FIG.

FIG. 13 is a flowchart showing only the main part of the door opening/closing command program. In step S, the car position floor is set as the scanning floor, and steps 82 to Syh Sto
- At St+, a door open 9 door close command is determined, and step S is performed according to the result.

and S. If the determination of the assigned floor in step S6 is NO, the process moves to step S11 and the door closes. Note that even if there is an allocation, if the determination in step S7 is YES, step S,
If the answer is No, the process advances to step S6 to stop opening the door. In this way, when the waiting time of a car that has received a door-closed standby command exceeds a predetermined time, the door-closed standby command and the prohibition of additional allocation for that car are invalidated.

FIG. 14 is a flowchart showing a car suspension setting program, in which it is determined in steps S1 to S whether the car is stopped with its door closed and in no direction. The process moves to step S4 only when the process is stopped at , and in other cases, the process proceeds to step S. Move to. step s
℃ in loe 811 is a part that performs processing when the car cannot enter the hibernation state, and in step StO, the operator sets the hibernation timer setting value (for example, 1) to the hibernation timer.
80 seconds), and the pause command is canceled in step S□. In addition, steps S and ~S are parts that perform processing to output a suspension command when the basket enters a dormant state, in which the basket position is set in step S, and the floor at which the basket is located is set at the door. Check whether it is a closed standby reservation assigned floor, and if yes, proceed to step S and pause the pause timer for the elapsed time from the previous calculation in order to set the pause timer earlier than when moving to the normal pause state. Step S after subtracting by the value multiplied by the promotion coefficient (for example rlOJ),
Move to. Also, if one unit is not on the floor assigned to a closed standby reservation,
In step S6, only the elapsed time since the previous calculation is subtracted as usual, and then the process moves to step S. In step S7, it is determined whether the pause timer has become "0" or less, and if yes, a pause command is set in step S. Furthermore, regarding the 14th cause, TK
is memory for the pause timer, and KS is a predetermined value (for example, is.

seconds), SEC is the elapsed time (seconds) since the previous calculation.

Kn is a pause promotion coefficient, and SD is a pause command.

As explained above, according to the elevator reserved operation control device according to the present invention, during reserved operation, a car that receives a reserved door closed standby command and waits on a waiting floor with its door closed enters the normal rest state. Since it is possible to enter the hibernation state earlier than the specified time, it has an excellent effect of preventing energy wastage and saving energy.
