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, it is capable of automatically and easily operating an elevator in a desired mode at a scheduled date and time, as well as reserving a car to a specific floor. In contrast, this invention relates to an elevator operation reservation control device that prevents deterioration of general service.

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.

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 when a car is reserved on a specific floor and left on standby, no passenger appears at the reserved time. In some cases, waiting on a specific floor is disabled to prevent a decline in general service.

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

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. That is, the group management device 20 selects and operates the specified number of cars to 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 wait with the door closed or to respond by opening the door 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.
And in this example, 001 to 999
999 reservations can be made, and each reservation can be called YTj (j = 001 to 999) by adding a suffix j to the reservation table YT, as shown in Figure 3b. It is made up of 0 to 15 columns in which reserved contents are entered for each column. Each column is configured to correspond to one byte (8 bits) of memory, 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 determination in step _S3 is YES, the process moves to step _S4 , where the reservation number is displayed. Then, when the 3-digit reservation number is input, steps _S5 to _S6 ,
After executing S ₇ , 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. In the same way, steps S _7d to S _7f indicate the start time, steps S _7g to _{S 7i} indicate the end time, steps S _8a to _8e indicate the floor, and steps S _9d to S 7i indicate the end time.
The number of cars is input in S _9c , and the designated car number is input in steps S _9d to 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 determination in step _S5 is NO, the process moves to step _S6 to determine whether or not that day is the current day, and if it is not the current day, the process moves to step _S10 , which will be described later. do. 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
In _{step S8} , it is determined whether the current time is included in the reservation time range, and if it is within the range, the j-th 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 ,
Set the reserved floor to m as the scanning floor and step
In _S9b , the number of cars waiting with the door closed is set in YCDm as the specified number. And step
In _S9c , it is determined whether the car is designated or not, and if the answer is NO, the car directly heads for the exit, and if the answer is YES, the process of setting the designated car number (the number of the car waiting to close the door) in YCKm is executed.

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 allocated number satisfies the designated number of cars for closing the door, and in step _S5 , an additional allocation signal for closing the door is generated. Furthermore, in Figure 9,
YCDm is the specified 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". We are looking for the number of cars that are used (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 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. , NASKn indicates an additional allocation prohibition signal for unit n, and YCKm indicates the door closing standby command car number for 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 of the expected arrival times for upstream and downstream. 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 car nth on the m floor is smaller than the value of the previous car. If it is smaller, in step S _6i
Set the machine number as the selection basket and reset the TY value at the same time. Such operations in steps S _6h and S _6i are similar to steps S _6k and S _6l .

Figure 12 processes the cancellation of upstream and downstream assignment commands AKUm and AKDm for a car that has been given a door-closed standby command, as well as the cancellation of the door-closed service command and prohibition of additional assignment for a car that has been on standby for a predetermined period of time. . Then, in step _S1 , the cut-off period of the scanning car is set, and in steps _S2 to _S10 ,
Scan all the cars one by one. Here, in step _S4 , it is determined for each car whether or not the floor on which the car is located is a car for which a door closing service command has been received, and if YES, step _S5 is performed.
Step only when the car is stopped and has no direction.
In step S ₆ , the up and down assignment signals for the car position floor are canceled and preparations are made so _that the next time a hall call for that floor is registered, the assignment process will be performed again. . Next, in step _S7 , the waiting time is calculated by adding the calculation cycle from the previous time indicated by SEC. Next, in step _S8 , it is determined whether the waiting time calculated in step _S7 is greater than or equal to a predetermined value, and if YES, in step _S9 , A process is executed to cancel the door closing service command for the car position floor and the prohibition of additional allocation for car n.
In addition, in Figure 12, TKn is the nth machine time, K
is a predetermined value, for example, 30 seconds, and SEC is the calculation cycle of the program, and is set to 0.1 when processing is performed every 0.1 seconds, for example.

Figure 13 shows the process of making the additional allocation prohibition signal set in Figure 10 valid during the period when the door closing service command is issued, and clearing the standby time during the period when the additional allocation signal is not issued. Execute the processing to be performed. In other words, all the cars are scanned one by one in steps _S2 to _S9 , but if it is determined in step _S3 that additional allocation is prohibited, then in steps _S4 to _S7 , the car is scanned one by one. It is determined that there is no door closing service on all floors. If the determination in step _S7 is YES, the prohibition of additional allocation is canceled in step _S8 . on the other hand,
If the judgment in step _S3 is NO,
At step _S10 , the waiting time is always set to 0 for cars for which additional allocation is not prohibited.

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 NO, proceed to step _S8 and stop the door opening.

FIG. 15 is a flowchart for explaining another embodiment of the elevator operation reservation control method according to the present invention, in which the predetermined value K in the flowchart shown in FIG. 12 can be changed. be. In this embodiment, by substituting the value of TKT for K, when the average waiting time is long, by setting the allowable waiting time K of the standby command car to a short value, it is possible to prevent the deterioration of the service. This is to prevent In this Figure 15, steps _S1 to _S10 calculate the current average waiting time,
The waiting time of the serviced call is taken into SUMT, the number of times is taken into NO sequentially and added,
We are looking for the average waiting time for calls that are registered and serviced closer to SUNT/NO. Therefore, when NO reaches the predetermined value HK, the subsequent addition operation is stopped and the number of HK is matched.
To obtain SUNT, reduce SUNT by 1/HK and add the waiting time for the new call. For this reason, the average time AVT will continue to be affected by the previous influence, but the closer it is, the more strongly it will be weighted in calculation. Furthermore, for the AVT calculated in step _S11 , the allowable waiting time is calculated using a predetermined functional formula, and if this is equal to the predetermined value β, the value is α + γ, and if β>AVT, the allowable waiting time is calculated. for
TKT is large and becomes small when β<AVT. Note that step _S3 is to measure the timing of canceling the call, and step _S4 is to determine whether the call number memory has reached HK.If the determination is NO, step _S6 , _S7 , _S8
The average waiting time in the correct sense can be found by
If YES, a simplified average time is determined in steps S ₅ , S ₇ and S ₈ . Step S ₁₀ is a program for a downstream call;
Since it is exactly the same as S ₁ to S ₉ , a detailed explanation thereof will be omitted.

In this Figure 15, NO is the call number memory for creating the average waiting time, and HK is the predetermined value (e.g.
10 pieces), SUNT is the total waiting time of calls for the number of calls NO, AVT is the average waiting time in simplified form for the current traffic, TKT is the allowable waiting time, α,
β and γ are coefficients.

Effects of the Invention As explained above, the elevator operation reservation control device according to the present invention makes reservations for elevator operation based on a time schedule, and when a car is reserved for a specific machine and placed on standby, it is possible to If a passenger does not appear, waiting on a specific floor is invalidated, which has the excellent effect of preventing a concomitant deterioration of general service.
