Abstract

PURPOSE:To respond to a hatch call instantly by composing the system to allot a hatch call of the cage forcibly for instant turning back, even though the hatch call is in the direction reverse to the forcible selection direction, when the hatch call is made at a floor where the cage is reaching or is stopped after a response with the door open. CONSTITUTION:When a cage is going to reach a floor responding to a final cage call and it detects no allotment of a hatch call to the cage and no cage call other than that from the reaching floor, a final cage call operation control means 13 selects a moving direction of the cage forcibly. And when a final cage call reaching hatch call detecting means 17 detects a hatch call when the cage is going to reach the final cage call floor or the cage is stopped, the allotment is given forcibly to the reaching or stopped cage for the cage call by a selecting direction converting means 14, and the selecting direction is converted forcibly to the direction necessary to respond to the hatch call. As a result, the hatch call can get a response instantly.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to an elevator group management control device.

(Prior Art) In general, a conventional elevator group management control device does not provide a position indicator at a landing, but instead provides a hall lantern 1 and a hall chime 2, as shown in FIG. This is because group management control allocates the optimal car to each hall call so that service is uniform.
This is because the car may jump over or turn around in response to a hall call, so it is necessary to hide the car position from waiting passengers at the hall. Waiting customers are notified of the response in advance.

In such an elevator group management control device,
When the final call is a car call and there is no other car call or hall call, and you respond (hereinafter, this response is referred to as the final car call response), it is actually a non-directional call, but you arrive without a direction. Both the hall lantern and hall chime do not work when the elevator car is on the floor and the door is opened, so it is strange for a passenger who is attempting to use the elevator from the landing on the floor where the elevator stopped after answering the last car call to see the door suddenly open. It will give you a feeling. In order to avoid this, the hall lantern and hall chime are operated by forcibly giving direction to the car when responding to the final car call.

Figure 7 shows the operation of such a conventional example.
Figure a) shows that a certain car 3 is responding to the final car call in the upward direction, and figure (b) shows that the car 3 is opening its door after responding to the final car call. ing. And this car 3 is forced to select upwards,
Upper hall lantern 1 is blinking.

The timing chart of the response operation at this time is shown in Fig. 8. Point a corresponds to the timing shown in Fig. 7(a), and car 3 is traveling upward at the rated speed. be. Then, from this timing a to 3, the speed is decelerated,
The hall lantern 1 starts blinking, the hall chime 2 starts operating, and thereafter the hall lantern 1 repeats blinking even while the door is open as shown at point 2.

(Problem to be Solved by the Invention) However, in such a conventional elevator group management control device, when a hall call is made for the floor while the car is stopped at the last car call response floor, the direction of the hall call is There was a problem in that a sufficiently early landing call could not be obtained when the direction was opposite to the forced selection direction.

To explain this in more detail, Fig. 9 shows the movement of the elevator when a downward hall call for a stopping floor is registered in the state shown in Fig. 7(b). In this case, the final car call response car is car A, and car B is the optimal car to which the registered down hall call is assigned.

Currently, since car A is the last car to answer car calls, the upward selection is forcibly made on the relevant stop floor.
As shown in Figure (a), when a downward landing call is made on the stopping floor while the A car is stopped, the A car responds to the downward landing call because the call is from behind. On the other hand, there is a low possibility that the optimum car will be determined; for example, car B, which is on an upper floor and is operating in a downward direction, will be assigned as the optimum car.

However, at this time, the upward selection of machine A has actually been temporarily determined, and if this machine A was forced to select the downward direction, then this machine A would be considered the optimal machine. will be assigned, and those who have registered for the down hall call will be able to board Car A without waiting. When the B-car actually responds to the downward hall call and arrives at the hall call floor, if no other hall call has occurred in the A-car, it will be in a standby state as shown in Figure 9(b). It remains where it is.

This indicates that the response of the elevator is poor because direction selection is forcibly performed when responding to the final car call.

In addition, in the state shown in Fig. 7(b), when the stop floor is near the upper terminal floor, a lower hall call for the stop floor is registered, and the optimally assigned car for this lower hall call becomes the last car call response car. It is shown in FIG. 10(a). In this case, the car closes its door once, changes direction, opens the door again, and responds to the hall call, as shown in FIG. 3(b). Therefore, in this case, the person who called the landing will have to close the door and then wait until it opens again, but in this case as well, if you have selected the downward direction from the beginning, the door will close once. Since no action is performed, a faster response can be achieved.

The present invention has been made in view of these conventional problems, and provides an elevator group management control device that can quickly respond to a new hall call at the stopping floor of the car that has responded to the last car call. [Structure of the Invention] (Means for Solving the Problems) The elevator group management control device of the present invention issues a hall call in response to the operation of a hall call button provided on each floor. a hall call registration means for registering; a hall call allocating means for selecting and allocating the most suitable car to service the hall call registered by the hall call registration means from among a plurality of elevator cars; a direction selection means for selecting a moving direction of a car in response to a landing call and a car call, and a direction selection means for selecting a moving direction of a car in response to a car call; A final car call operation control means for forcibly selecting the moving direction of the car when there is no call, and a direction being forcibly selected by the operation of this final car call operation control means, so that the car responds and lands on the floor. a final car call landing floor landing call detection means for detecting a new registration of a landing call for a floor where the car is currently running or a stopped floor; When a car whose direction has been forcibly selected by the final car call operation is about to land on the floor where a landing call has been registered or is stopped at the floor, a new landing call is registered for the car. and a selection direction switching means for forcibly allocating a selection direction and switching the selection direction to the same direction as the hall call.

(Function) In the elevator group management control device of the present invention, when a certain car is about to land in response to the final car call, there is no hall call assigned to that car, and no car calls are made to floors other than the expected landing floor. When this is detected, the final car call operation control means forcibly selects the moving direction of the car.

When the car is about to land on the last car call floor or is stopped, when the final car call landing floor landing call detecting means detects the landing call of the floor, the selection direction switching means causes the car to land on the floor. To forcibly allocate a car that is about to start or stop to the hall call, forcibly switch the selection direction to a direction necessary for responding to the hall call, and quickly respond to the hall call.

(Example) Hereinafter, embodiments of the present invention will be explained in detail based on the drawings.

FIG. 1 shows an embodiment of the present invention, which is roughly divided into a plurality of single control devices 11 that control each of a plurality of elevator cars, and a common control device that performs group management control of a - group of elevator cars. It consists of 12.

Each single control device 11 includes a final car call operation unit 13 that determines whether or not it is a final car call response and outputs a forced direction selection command of upward or downward during the final car call response; The car call and final car call operation unit 13 includes a direction selection unit 14 that selects a direction based on a forced direction selection command output from the car call operation unit 13.

The common control device 12 also includes a hall call registration unit 15 that registers hall calls, a hall call allocation unit 16 that assigns the registered hall calls to the most suitable car, and a forced direction selection based on the final car call. The terminal includes a final car call landing floor landing call registration detection unit 17 that detects that a landing call for the landing floor has been registered.

Next, the operation of the elevator group management control device having the above configuration will be explained.

When one of the elevators attempts to land in response to a car call, if it is detected that there is no hall call assigned to that car and there are no car calls on floors other than the expected landing floor, the final car call operation unit 13 outputs an upward or downward forced direction selection command to the direction selection unit 14, and the direction selection unit 1
4 manually inputs this forced direction selection command and selects the commanded direction.

The forced direction selection command is also output to the last car call landing floor landing call registration detection unit 17 of the common control device 12, and the last car call landing floor landing call registration detection unit 17 performs the same process in consideration of other individual control information. It is detected at which floor the car of the car is performing forced direction selection by the final car call response.

The final car call landing floor landing call registration detection unit 17 inputs the hall call registration table of the hall call registration unit 15 and the hall call allocation table of the hall call allocation unit 16, compares the two, and detects any unallocated hall calls. In this case, if a car that is decelerating or stopping to land on the floor of this hall call has made a forced direction selection by the final car call, and this selected direction and the direction of the hall call are opposite, that car call The operation unit 13 is instructed to reverse the forced selection direction, and the hall call allocation unit 16 is instructed to allocate to the car.

In this way, for example, when the car is stopped at the last car call response floor shown in FIG. 7(b) and a downward hall call is registered at this stopping floor, this car is immediately assigned,
The upward forced selection command up to that point is reversed, and the command shown in Fig. 10 (
As shown in b), this downward hall call will be answered.

Further, the operations of the final operation section 13 and the final car call landing floor hall call detection section 17 will be explained in detail with reference to the flowcharts of FIGS. 2 and 3.

FIG. 2 shows a flowchart of the operation of the final car call operation section 13. First, it is determined in step SL whether deceleration has started while the car is running.

S2), Next, if there is only a car call on the landing floor, it is determined whether or not a hall call is assigned and there is no car call on a floor other than the landing floor (steps S3 to S5). During deceleration running, the landing floor is fixed, and if there is no other call other than a car call at the landing floor, the car becomes directionless, so a forced selection command in the same direction as the driving direction is output ( Steps 56-S8).

This forced selection command is determined in steps Sl and S9 as to whether or not the door was closed during the stop, and if the stop door was closed, the landing door was opened and then closed, so the next forced selection command is output. (step 510).

Further, if the conditions are reversed in the judgments in steps S2 to S5, it is possible that another call has occurred during deceleration running, and therefore, the forced selection output is also stopped in step SIO.

Further, if the door is stopped and the door is opened in steps SL and S9, the state immediately before the door is stopped and opened is maintained.

When a forced selection direction reversal command is input from the final car call landing floor landing call detection unit 17 of the common control device 12, it is determined whether there has been a forced selection direction selection command up to that point (step 511), and whether there has been a forced selection direction reversal command. Please make a decision (step 512), and reverse the direction of the forced selection command that has been output (steps 313 to 516).
).

In addition, once the selection command direction reversal command is output, in order to maintain the on state until the corresponding hall call is deleted, in steps S13 to S15, the direction of the forced selection command is once outputted so as not to repeat the reversal. Once it is reversed, the reversal direction is latched to prevent it from reversing again. Further, in step S17, since the direction of the forced selection command continues to be set while driving, steps S13 to S
This is a process for not performing latching after once inverting 15.

Next, the detailed operation of the final car call arrival floor call detection section 17 will be explained based on the flowchart of FIG.

The final car call landing floor call detection unit 17 first detects the final car call operation unit 13 of all cars under group control of the - group.
A check is made to see if a forced selection command has been output (step 521). If there is a car that is outputting, then the landing floor of the car of the output car is set at a position using the car number as an index in table X shown in FIG. 4 (step 522).

As shown in FIG. 4, table X is arranged in the order of machine numbers, and has a 1-byte area for each machine number. The data in the area for each car indicates the floor on which the car is about to land or is stopped when it issues a forced direction selection command, using a relative value with 1 being the lowest floor.

When this data is zero, it indicates that the corresponding machine is not outputting a forced direction selection command.

Next, in steps S2B and S24 of FIG. 3, it is checked whether there is an unassigned (newly registered) call among the hall calls indicated by the non-zero floors in table X. and,
If there is such a call, compare the direction of the hall call with the forced selection command direction output from the car indicated by the detected element of table X, and if the direction is opposite, set the forced selection direction reversal command to table Y. (Steps S25, 26).

Here, table Y is arranged in the order of machine numbers like table X, as shown in FIG.
It has a part-time job area. The area data for each car indicates the direction and floor of the hall call, which is the basis for outputting the forced direction reversal command for that car. The direction is upward when the upper two bits are [01], downward when it is [10], and the floor is indicated by a relative value with the lowest floor being 1 in the lower six bits. Furthermore, when this data is zero, it indicates that the forced direction selection reversal command is not being output to that machine.

Then, the data of this table Y is outputted to each final car call operation section 13 on the car number side.

The data in table Y also serves as an allocation command to the hall call allocation section 16. Therefore, when allocating an unallocated call in the hall call table, if there is data indicating the floor and direction of the hall call in this table Y, the hall call allocating unit 16 Forcibly allocate a landing call to.

The data in table Y indicates the time at step S when a car that has been forcibly assigned by table Y clears its hall call.
27 and 32g and cleared in step S29.

In this way, in the elevator group management control device of this embodiment, when a certain car is about to stop at the landing floor in response to the final car call, or while the car is stopping, the car is forced to stop at the landing floor in advance. If a hall call is registered in the direction opposite to the direction of movement given by It is possible to immediately respond to a hall call according to the direction of movement of the vehicle.

〔Effect of the invention〕

As described above, according to the present invention, when a direction is forcibly selected for a car whose door is open during response to the final car call and after the response, the door is stopped on the floor on which the car is about to land or when the door is stopped opening after the response. When a hall call occurs on the middle floor, even if the hall call is in the opposite direction to the forcibly selected direction, the hall call of the car is forcibly assigned and the direction is immediately reversed. In this way, when a car is responding to the final car call and is about to stop at the car call answering floor, or a car that is stopped becomes a rear call, other cars are not assigned to the hall call in its place, and the car is immediately stopped. It is possible to respond to hall calls at any time, improving service to passengers, and also making effective use of empty cars, thereby improving the service of the elevator as a whole.
