Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to an elevator operation reservation control device, and in particular to an elevator operation reservation control device that can automatically and easily operate a desired mode at a scheduled date and time, and that can also operate according to the standard of general service. The present invention relates to an elevator operation reservation control device that prevents deterioration of service by disabling part of the operation of the reservation operation.

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

However, the staff must operate the mode switch accurately at the scheduled time, which is an extremely troublesome task. In addition to this mode switch, there are many switches such as a meeting room operation switch and a service disconnection switch, and it is extremely difficult to operate these switches accurately without forgetting to operate them at the scheduled times. In this case, when the switch is scheduled to be switched on at the same time every day, such as when driving to work, a clock is used to automatically turn on the switch at a predetermined time, thereby eliminating the need for staff to operate the switch. .

However, in elevator operation control using the above-mentioned clock, it is suitable for switching control that is constant every day, but it is suitable for switching control that is constant every day, but when changing the time set on the clock or when an important customer comes to the office, etc. This has the problem that it is extremely difficult to set the time for a schedule where the time is not fixed. Furthermore, if there are many reserved trips to specific floors, there is a problem in that general services will be significantly degraded, causing inconvenience.

SUMMARY OF THE INVENTION Therefore, the elevator operation reservation control device according to the present invention makes elevator operation reservations based on a time schedule, and invalidates the reserved operation in which the elevator waits depending on the level of general service of the elevator. This prevents a decline in general services.

Reservation information for elevator operation supplied from the input device 2 is taken in. Reference numeral 3 denotes a reservation operation control section which takes in reservation information supplied from the elevator operation reservation input section 1 and compares it with timing information supplied from a timekeeping section 4 having an automatic calendar and a clock to determine the current execution. It selects the reservation information to be requested and outputs it as an operation control signal.
Reference numeral 5 denotes an elevator reservation operation unit which takes in operation control signals supplied from the reservation operation control unit 3 and operates the elevator 6 based on input information (hall call, in-car call, etc.) supplied from the elevator 6.
A reservation service order will be issued. On the other hand, the elevator 6 executes operations based on the reserved operation command supplied from the elevator reserved operation section 5. Reference numeral 7 is a reserved operation invalidation control section, which detects the general service level of the elevator 6 that operates according to instructions from the elevator reservation operation section 5, and restricts the reserved operation of the elevator according to the detected value. 3 and the elevator reservation operation section 5.

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, 10 is a car control device, and in particular only the car control device for one elevator is shown. The car control device 10 includes a central processing unit 11 and a transmission element 1 connected to the central processing unit 11 via a data bus 12.
3, a memory 14 and an interface 15 that takes in information supplied from an external device 16. Reference numeral 20 denotes a group control device for efficient operation by controlling the operation of each elevator, and includes a central processing device 21, a transmission element 23 connected to the central processing device 21 via a data bus 22, 24, memory 25, interface 28 that captures the signal of the ride call button 27
and a clock 29. The transmission element 23 serially transmits information between it and the transmission element 13. Further, the clock 29 has an automatic calendar function, and is configured so that the calendar, month, day, date and time are automatically updated. Reference numeral 30 denotes a statistical device for statistically processing the operation status and service status of the elevator, and is a statistical device that is operated by a central processing unit 31, transmission elements 33, 34, and a memory 35 connected to the central processing unit 31 via a data bus 32. It is structured as follows. The transmission element 33 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 MULTI16 is used. The personal computer 40 includes a central processing unit 41, a transmission element 43, a memory 44, and interfaces 45 to 47 connected to the central processing unit 41 via a data bus 42. The transmission element 43 serially transmits necessary information to the transmission element 34, and the interfaces 45 to 47 serve as peripheral devices for the personal computer 40, such as a display device 50 and a floppy disk device 60.
and a keyboard 70, respectively.

In the apparatus configured in this manner, an attendant or the like operates the personal computer 40 and then operates the keyboard 70 to input the details of the reservation in a predetermined format. Of the input information and the information corresponding thereto, 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 and transfers this program to the memory 44 provided inside the personal computer 40.
At the same time, predetermined processing is executed according to this program. The reservation information entered using the keyboard 70 is transmitted to the transmission element 4.
3 and 34 to the statistical device 30 and stored in the memory 35. In the statistical device 30,
By operating the central processing unit 31 according to the program stored in the memory 35, the automatic calendar program reads out the month, day, day of the week, and time of the current day, and based on this information, the reservation that has been taken earlier is made. Scan the information and select the appropriate reservation information. That is, scanning the reservation information retrieves the reservation information corresponding to the input date and time added to the reservation information. Next, the reservation contents of the retrieved reservation information are converted into a reservation operation control signal suitable for use by the 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 group management device 20
is generally used, and selects the most suitable car according to the information from the hall call button 27 and executes the allocation process. The group management device 20 immediately executes the given operation by constantly detecting the reserved operation control signal.
Here, the operations that can be executed include dispatching a car,
This is possible in a variety of ways, such as selecting a service pattern, changing the main floor, specifying or changing a specific floor (VIP floor, etc.), specifying a service separation floor, etc., but in this explanation, it is possible to select a car to any floor. Only the distribution of the number of vehicles will be explained. In other words, the group management device 20
The specified number of cars are selected and operated on the floor specified by the reservation operation control signal supplied from the statistical device 30. Further, for the selected car, a service command to the floor and a command including whether to close the door and wait or open the door and respond are given. This command is transmitted from the transmission element 23 to the transmission element 13.
The car control device 20 executes control for the selected car.

FIG. 3a is an explanatory diagram of a reservation table handled by the personal computer shown in FIG.
After being created in the memory 44 provided inside the floppy disk device 60, the data is stored in the floppy disk device 60 via the interface 46.
In this example, 999 from 001 to 999
Individual reservations can now be made, and each reservation can be made by adding suffix j to the reservation table YT.
It can be called YTj (j=001-999), and is composed of 0-15 columns in which reserved contents are entered for each column, as shown in FIG. 3b. And one column is one byte of memory (8
It is structured to correspond to bits), and each column contains numbers or letters using ASCII code.

FIG. 4 shows a program that is stored in the floppy disk device 60 and transferred to the memory 44 of the personal computer 40 when executed, and particularly shows a reservation input processing program. First, when the personal computer 40 starts operating, the display device 5 is activated in step _S1 .
“YOYAKU?” is displayed at 0. Next, when the keyboard 70 is used to input "DYS", which indicates the display, the process moves from step _S2 to step _S10 , and when the character "YES" is input, the process moves to step _S3 , where other characters are input. If so, the process returns from step _S3 to step _S1 . If the judgment in step _S3 is YES,
By moving to step _S4 , the reservation number is displayed. Then, when the 3-digit reservation number is input, steps S ₅ to S ₆ , S ₇ ,
After executing S ₈ and S ₉ , the process returns to step S ₁ again. Here, step _S7 is a date and time input program, step _S8 is a floor input program, and step _S9 is a reservation cart column 14-15 input program. As shown in a, b, and c, these are prepared in advance as subprograms.

On the other hand, when the process moves from step _S2 to step _S10 , a reservation number display process is executed, and the process returns from step _S11 to step _S10 until the next reservation number is input. Then, in step _S12 , after setting the input reservation number to j,
Move to S ₁₃ . In step _S13 , the reservation details of the previously input reservation number are displayed on the display device 50, and when "CNCL" is input next, the process advances to step _S16 , thereby clearing all the reservation details. By returning to step S ₁ , the process ends with only displaying and clearing the reservation details, and if it is other than this (other than "CNCL" or "OK"), the reservation is returned to step S ₁₃ . Executes content display processing.

5a, b, and c are subprograms used in the program shown in FIG. 4. For example, in step _S7a , "HIZUKE" is displayed on the display device 50,
When the digit number is input, the process moves from step S _7b to step S _7c . And step S _7c
In this case, the numbers entered in the column containing the date are stored and processed. Similarly, steps S _7d to _{S 7f} indicate the start time, steps S _7g to _{S 7i} indicate the end time, steps S _8a to _{S 8c} indicate the floor, and step S _9a
The number of cars is input in ~S _9c , and the designated car number is input in steps S _9d ~ S _9f .

FIG. 6 shows a program stored in the memory 35 of the statistical device 30, which creates a reservation operation control signal from the reservation table transmitted from the personal computer 40 and the date and time read from the automatic calendar. It is assumed that this program is repeatedly processed once per minute, and that reading of the date and time, etc., has already been read by another program. Then, in step _S1 , 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 _S2 . and,
In steps S ₂ to S ₁₀ , the reserved table is set to 001.
Scan up to 999 to create a reserved operation control signal.
However, in step _S4 , it is determined whether the reservation details are not "0", and in step _S5 , the dates are determined, and if the dates are all "0", the reservation is made every day. The process moves to step _S7 to be processed. Furthermore, if the judgment in step _S5 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 proceeds to step _S10 , which will be described later. Transition. Also,
If the determination in step _S6 is YES, the process proceeds to step _S7 , where the start time and end time are determined, and it is determined whether or not the reserved operation is selected only once. Then, if it is not only once, step
Step _S8 determines whether the current time is included in the reservation time range, and if it is within the range, the jth reservation content (columns 12 to 15) is converted into a control signal in step _S9 . . Also, the judgment in step _S7
If YES, the process moves to step _S9 only if the current time and the reserved time match. In addition,
If you select only one operation, the control signal will continue to be generated for one minute, and there is a concern 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 _S9 , the program for creating the reservation control signal for the j-th is called, and after this processing is executed, the operation returns to steps _S10 and _S3 .

Note that FIG. 7 is _a subprogram of _the scan reservation number update program shown in step _S1 in FIG. The scanning floor is updated, and in step _S3 , the designated number of cars with closed doors is cleared, and then in step _S4 .
At this point, an operation for clearing the door-closed standby designated car is executed for all floors.

FIG. 8 is a subprogram of the part shown in step _S9 of the flowchart shown in FIG.
A reservation operation control signal is created from the contents of the reservation. And in step S _9a ,
Determine whether reserved operation is prohibited,
If NO, proceed to step S _9b , set the floor m for reservation, and enter the specified number of cars in step S _9c .
If there is a designated car, the designated car number is set to YCKm in step _S9e .

Figure 9 shows that when the number of waiting cars with closed doors is specified, it is checked whether the number of allocated cars for the specified floor satisfies the specified number, and if the number is not satisfied, the allocation program This is to issue an additional assignment signal for closing the door. Then, as shown in FIG. 9, all floors are scanned in steps _S1 to _S7 , and it is determined in step _S3 whether or not the designated number of vehicles exists on the m floor. Further, in step _S4 , it is determined whether the number of vehicles assigned to close the door satisfies the designated number of vehicles to close the door, and in step _S5 , an additional assignment signal for closing the door is generated. In Figure 9, YCDm is the designated number of waiting cars with closed doors to the m floor,
ATCm indicates the door closing additional assignment signal for the m floor, AKCm indicates the number of door closing service commands (assigned number) for the m floor, and the door closing service command DCmn for the m floor is scanned for all units, and is set to "1". I'm looking for a traditional basket (program omitted).

FIG. 10 shows an allocation program for the standby service with the door closed, and this program includes an additional allocation process when specifying the number of waiting cars with the door closed and an allocation process for the designated car number. and,
In steps _S1 to _S13 , all floors are scanned, and in steps _S11 → _S12 → _S8 , the assignment process for the designated car number is executed, and in step _S4 , the assigned car number is The presence or absence is determined, and if there is a designated car, the process advances to step _S11 , where it is determined whether a command (assignment) for the designated car has already been issued. If the car has not been specified, the process moves to step _S12 , and the process moves to step _S8 in order to make the specified car the command car. However, it goes without saying that the designated car command must be processed prior to the car number command.

Next, in step _S8 , 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 _S3 ,
Proceeding to step _S13 , processing is executed to clear the door closing service command for the m floor for all cars. This means that when the m-floor landing call is registered,
This is to enable immediate assignment and execution of services. Further, in steps _S5 to _S8 , it is determined whether or not a door closing additional allocation signal is issued in response to an additional command for the specified number of cars, and in step _S6 , it is determined whether or not a door closing additional _allocation signal is issued.
A door closing service command car for the floor is selected and the car is imported into KAGO. The car selected in this way receives an allocation and door closing service command in step _S8 , and furthermore, in step _S9 , additional allocation is prohibited for the car to which the door closing service command has been given. , subsequent allocation processing is prohibited so that the door can be placed on standby with the door closed on the designated floor. Note that the prohibition on additional allocation to cars for which there is no door closing service command on all floors must be immediately lifted after processing the flowchart shown in this Figure 10. The result will be as shown in Figure 13. In addition, in step _S20 , the prohibition of reserved operation is detected, and if YES, the process always moves to step _S13 to clear the door closing service command. Further, step _S21 is provided between steps _S8 and _S9 , and when the prohibition of additional allocation is disabled, even if a door closing service command is given, additional allocation will be enabled and the general call will also be disabled. Run the service. In this Figure 10, ATCm is an additional assignment signal for closing the door to floor m, AKUmn is an assignment command for machine n going up floor m, AKDmn is an assignment command for machine n going down floor m, and DCmn is an assignment command for machine n going down floor m. , MASKn indicates an additional allocation prohibition signal for machine n, and YCKm indicates the door closing standby command car number on floor m.

FIG. 11 is a flowchart showing an example of a subprogram used in step _S6 of the flowchart shown in FIG. 10, and is for selecting 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 m floor earliest, and compare the car with the longest expected arrival time for each car on the up and down trips. The shortest one is selected, and the selection basket is first cleared in step _S6a . Next, in step _S6b , the expected arrival time of the selected car is set to the maximum value, and in steps _S6c to _S6j , all the cars are scanned. In this case, in step _S6e , the nth machine determines whether additional allocation is prohibited, and in step _S6f , the nth machine determines whether or not the mth floor is receiving door closing service. Then, in step S _6g , select the larger expected arrival time for upstream and downstream, and if the upstream is large, execute steps S _6h and S _6i , and if the upstream is small, execute steps S _6k and S _6l . Process. Then, in step S _6h , it is determined whether or not the expected arrival time of the n-th floor on the m floor is smaller than the previous value of the car, and if it is, in step S _6i , the n-th car is simultaneously set as the selected car. Reset the TY value. Such operations in steps S _6h and S _6i are similar to steps S _6h and _6l .

FIG. 12 is for creating an additional allocation prohibition invalidation signal that invalidates a part of the reserved operation and a reserved operation prohibition signal that invalidates the reserved operation completely.
The criterion for setting a signal is based on the waiting time of the longest waiting call, and _{the signal} setting is determined based on the waiting time of the longest waiting call. Choose a long one. and,
This maximum waiting time is a predetermined value K ₁
If it is longer than K ₂ (K 2 > K 1 ), the prohibition of additional allocation is invalidated in step S ₁₀ , and furthermore, if it is determined in step S ₁₁ that the maximum waiting time is longer than K 2 (K ₂ > K ₁ ), step S In _{step 12} , it is possible to execute control to invalidate the reserved operation. In this Figure 12, MAXT is the current maximum waiting time of the long call.
WTUm is m floor climbing hall call duration, WTDm is m
Indicates the duration of the downstairs landing call.

Figure 13 shows how the up and down car assignment commands AKUm and AKDm are canceled when the door close standby command is given, and the additional assignment prohibition signal set in Figure 10 is sent while the door close service command is issued. In steps _S2 to _S13 , all the cars are scanned one by one. Then, in steps _S2 to _S6 , the additional command is canceled,
In steps _S7 to _S12 , prohibition of additional allocation is enabled. Next, in step _S3 , the car position floor is set as the scanning floor m, and in step _S4 , it is determined whether the car position floor has a door closing service command or not.
If YES, the process moves to step _S5 , where it is determined whether the car is stopped or not, and if YES, the process moves to step _S6 , where the allocation command is canceled. Next, in step _S7 , the processes of steps _S8 to _S12 are executed only when additional allocation is prohibited. If it is determined in steps _S8 to _S11 that there is no door closing service command on all floors, the prohibition of additional allocation is canceled in step _S12 .

FIG. 14 is a flowchart showing only the main part of the door opening/closing command program. In step _S1 , the car position floor is set as the scanning floor, and in steps _S2 to
In steps _S7 , _S10 to _S14 , a door open/close command is determined, and depending on the result, the process proceeds to either step _S8 or _S9 . If the determination of the assigned floor in step _S6 is NO, the process moves to step _S9 and the door closes. Even if there is an allocation, if the determination in step _S7 is YES, step _S9
If the answer is NO, proceed to step _S8 and stop the door opening.
