Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control apparatus for selecting an optimum elevator from a plurality of elevators and performing a service for a hall call.

[0002]

2. Description of the Related Art Generally, when a plurality of elevators are installed and service is provided to a plurality of floors, a control method called group management control of the elevators is employed. In this case, the elevator control device includes a single control device that individually controls each elevator, and a group management control device that selects and assigns an optimum elevator among a plurality of elevators to a hall call.

The group management control device comprises a hall call registration unit for registering a hall call from each floor, and an assignment control unit for selecting and allocating an optimal elevator for a call from the hall call registration unit. Then, the assignment signal assigned by the assignment control unit is output to the single control device of the corresponding elevator. The single control device controls the elevator of the own car based on the assignment signal and the operating state signal of the own car.

[0004] That is, in the elevator group management control system, when a hall call occurs, the allocation control unit of the group management control device selects and allocates an elevator that is most suitable for dealing with the hall call among a plurality of elevators. ,
The other elevators are controlled not to answer the hall call. In addition, when selecting an optimal elevator for a landing call, the goal is to reduce and equalize the waiting time at the landings on all floors.

FIG. 11 is a diagram for explaining the operation of an elevator according to the conventional group management control. Now, in a 12-story building,
It is assumed that two elevators A and B are installed, and that car A is located on the first floor and car B is located on the fourth floor. And
Car A has a car call A2 on the 10th floor, while Car B has 1
It is assumed that there is an assigned floor call B1 on the first floor and a car call B2 on the twelfth floor. In this state, it is assumed that the UP hall call A1 on the ninth floor occurs when the A-unit is opened on the first floor.

[0006] First, the UP platform call A1 on the 9th floor was called to the A-car.
Consider the case of assigning The predicted arrival time TA of the A-car up to the 9th floor is 13 seconds, and the predicted arrival time TB of the B-car up to the 11th floor is 10 seconds. In this case, assuming that five seconds have passed since the hall call B1 on the eleventh floor was registered.
The predicted arrival time (predicted arrival time + call duration) that can respond to the hall call on the eleventh floor is 15 seconds. Therefore, the hall call A1 (9th floor) and the hall call B1 (11
The average non-response time with the floor is 14 seconds, and the standard deviation of the non-response time is 1.4 seconds.

[0007] Next, call the UP floor of the 9th floor A1 to Unit B
Consider the case of assigning The predicted arrival time TB of Unit B to the ninth floor is 8 seconds, and the predicted arrival time TB of Unit B to the eleventh floor stops once at the ninth floor. The total stop time (6 seconds) and the running time (4 seconds) from 9 times to 11 times is 18 seconds. That is, 5 seconds are added to this, and the predicted response time is 2
3 seconds. Therefore, the average final response time of the hall call A1 on the ninth floor and the hall call B1 on the eleventh floor is 15.5 seconds,
The standard deviation of the non-response time is 10, 6 seconds.

From the above, if an appropriate car is assigned in consideration of the reduction and equalization of the waiting time at the landings on all floors, the overall response time is small and the degree of fluctuation of the non-response time is small. Call No. 9 on the 9th floor
Will be assigned to As a result, to passengers waiting on the ninth floor, it looks as if Car B had passed.
For this reason, elevators that are group-controlled to prevent the passengers waiting at the landing from being confused are not usually provided with a landing car position display device.

[0009] If a landing car position display device is installed, priority is given to prevention of passage rather than reduction of waiting time and equalization of landings on all floors, and elevators likely to pass the floor in response to a landing call. For example, the elevator car position display device is turned on only for an elevator that is to respond to a hall call, so that the movements of other elevators cannot be seen.

[0010]

However, the passage cannot be completely eliminated only by the assignment control by the assignment control unit of the group management control device. In other words, when the assignment control unit attempts to respond to an elevator that is likely to pass in response to a hall call, there is a delay in the signal from the assignment control unit to the single control device and a delay in processing, and therefore, a certain margin value in terms of distance is necessary. Because the elevator that is going to pass does not exceed the physically stoppable range for the hall call and whether it can be stopped reliably, a certain margin value in terms of distance is necessary. Therefore, when there is a positional problem due to the margin value, the assignment control unit cannot necessarily cause the elevator that is likely to pass to respond to the hall call.

When an assigned car and a non-assigned car are running side by side, there is a possibility that useless assignment changes frequently occur between the two cars. In this case, the non-assigned car is more constant than the assigned car. Only when you are likely to arrive off the floor, it is necessary to change the assignment so that it does not pass. Therefore, when the two cars are close to each other, a pass may occur. Further, when the location of the assigned car is immediately before the hall call, the passage may be permitted without intentionally changing the assignment.

[0012] Further, if the landing car position display device is not installed, or if only the landing car position display device of the car that responds to the landing call is turned on, the waiting passengers at the landing may not be able to see the movement of the entire elevator and may be uneasy. As a result, there is a growing demand for elevators to be able to be seen at the landing.

[0026]

Embodiments of the present invention will be described below. FIG. 1 is a configuration diagram of an elevator control device according to an embodiment of the present invention.

On each floor, landing call buttons 1a to 1n
Are installed, and the landing call input / output control units 2a-2
n is input to the group management control device 3 via n. The group management control device 3 includes a hall call registration unit 4 for registering a hall call from each floor, and an assignment control unit 5 for selecting and allocating an optimum elevator for the call from the hall call registration unit 4. The assigned signals assigned and assigned by the assignment control unit 5 are the single control devices 6a to 6m of the corresponding elevator.
Is output to

The single control devices 6a to 6m are provided for each of the elevator cars 7a to 7m, and individually control the elevator cars 7a to 7m, respectively. In addition, each of the elevator cars 7a to 7m is provided with a car call button 8a to 8m and a car call input / output control unit 9a to 9m. The single control devices 6a to 6m control the elevator of the own car based on the assignment signal from the assignment control unit 5 and the car call of the own car, and detect a landing call within a certain floor on the driving direction side of the own car. Sometimes, it responds to the hall call.

FIG. 2 is a flowchart showing the operation of the single control device 6 in the first embodiment of the present invention.
A case is shown in which a response is made to a hall call within a certain floor on the driving direction side of the own machine. First, each of the single control devices 6a to 6m detects the positions and operating directions of the elevator cars 7a to 7m of the own car (step 11). And
A search is made as to whether or not there is a hall call between the position of the elevator car and the next scheduled arrival floor (step 12).

Here, the processing contents in step 12 are shown in FIG.
This will be described with reference to FIG. FIG. 3 shows the configuration of the hall call table in the single controller 6. FIG. 3 (a)
Is an UP platform call table, and FIG.
The N hall call table is shown. The hall call information input from the hall call registration unit 4 of the group management control device 3 is stored in the UP hall call table or the DOWN hall call table in the memory of the single control device 6.

Now, it is assumed that there is a landing call in the UP direction on the ninth floor, and the elevator car 7 is traveling in the UP direction on the sixth floor toward the twelfth floor. When the current car position 6th floor, the UP direction which is the driving direction, and the 12th floor which is the next scheduled stop floor are detected, the single control device 6 determines that the driving direction is the UP direction. Refer to the hall call table,
The presence or absence of a hall call from the 6th floor of the elevator car position to the 12th floor which is the next stop floor is detected. In this case, FIG.
As shown in (a), since there is a hall call on the ninth floor, the hall call on the ninth floor is detected.

If it is detected that there is a hall call between the elevator car position and the next scheduled arrival floor,
It is determined whether or not the hall call is within a certain floor from the elevator car position (step 13). If it is within a certain floor, it is further determined whether or not the floor can be stopped in consideration of the deceleration distance. A determination is made (step 14). If it is possible to stop at that floor, the fact that the vehicle will stop at that floor is recorded in a memory (planned stop floor table) in the single controller 6 (step 15). Finally, it is determined whether or not the processing from step 12 to step 15 has been performed for all hall calls up to the next scheduled stop floor, and if not completed, the operation from step 12 is repeated (step 16).

As described above, according to the first embodiment, the elevator car 7 is stopped only when there is a hall call within a certain floor in the driving direction of the own car. It is possible to prevent the passage of the hall call without increasing the number.

FIG. 4 is a flowchart showing the operation of the single control unit 6 according to the second embodiment of the present invention.
This second embodiment is different from the first embodiment shown in FIG. 2 in that instead of responding to a hall call within a certain floor on the driving direction side of the own vehicle, This is to respond to a hall call whose predicted arrival time in the driving direction is within a predetermined time.

As in the case of the first embodiment, the position and the driving direction of the elevator car 7 are determined (step 2).
1) Retrieval of whether or not there is a hall call from the elevator car position to the next scheduled arrival floor (step 22). When it is detected that there is a hall call, the arrival time of the elevator car 7 up to the hall call is calculated (step 23). As a result of calculating the arrival time, it is determined whether or not it is within a certain time until the landing call (step 2).
4) If the floor can be stopped in consideration of the deceleration distance (step 25), the fact that the floor is stopped at that floor is recorded in the memory (planned stop floor table) in the single controller 6 (step 26). Finally, it is determined whether or not the processing from step 22 to step 26 has been performed for all hall calls up to the next scheduled stop floor. If not, the operation from step 22 is repeated (step 27).

According to the second embodiment, the elevator car 7 is stopped only when there is a hall call that can be reached within a certain time in the own driving direction, so that useless driving is increased. It is possible to more accurately prevent the passage of the hall call than to judge from the distance.

Next, a third embodiment of the present invention will be described. FIG. 5 is a flowchart showing the operation of the single control device 6 according to the third embodiment of the present invention, and FIG. 6 is a flowchart showing the operation of the assignment control unit 5 according to the third embodiment of the present invention. In the third embodiment, when an elevator other than the assigned car responds to the hall call first, the assignment of the assigned car is canceled.
This is to prevent the assigned car from repeatedly answering the hall call.

The single control unit also controls the stop of the elevators other than the assigned car at the intermediate floor stored in step 15 of FIG. 2 or step 26 of FIG. That is, in FIG. 5, when the elevator is decelerated at the scheduled stop floor (step 31), the single controller 6 detects the stop floor and the operation direction of the elevator car (step 32). Next, it is detected whether or not there is a landing call in the same direction as the driving direction of the elevator car on the stop floor (step 3).
3) If there is a hall call, a hall call erasure command is output to the group management controller 3 to erase the hall call (step 34).

The group management control device 3, as shown in FIG.
It is determined whether or not the hall call delete command has been input from the single control device 6 (step 35). If it is detected that the hall call delete command has been input, the number of the car that has output the hall call delete command is determined. Identify and detect (Step 3
6). Then, it is determined whether or not the car that has output the landing call erasure command is the assigned car stored in the assignment control unit 5 for that hall call (step 37). As a result, it is determined that the car is a different car. If it is determined, the assignment control unit 5
Cancels the assignment of the assigned car (step 38), and the hall call registration unit 4 deletes the hall call (step 39).

According to the third embodiment, it is possible to prevent passage of a hall call and to prevent useless driving due to the assigned car responding to the same floor later.

Next, a fourth embodiment of the present invention will be described. FIG. 7 is a flowchart illustrating the operation of the allocation control unit 5 according to the fourth embodiment of the present invention. In the fourth embodiment, when a plurality of elevators are running together within a certain floor, a single control device 6 for one elevator
In this case, the input of a hall call is permitted only to prevent a plurality of elevators from responding to the same hall call repeatedly.

In FIG. 7, a variable C1 representing an elevator car as a comparison source is set as an initial setting (step 71). Next, it is checked whether the elevator car represented by the variable C1 has directionality (step 72). If the checked elevator car C1 has a direction, a variable C2 representing an elevator car to be compared is set (step 73).

On the other hand, if it is determined in step 72 that the checked elevator car C1 has no direction,
An elevator car as a comparison source is updated as C1 = C1 + 1 (step 7F).

Next, it is checked whether or not the elevator car represented by the variable C2 has a direction (step 74). Checked elevator car C2
However, if it has no direction, the elevator car to be compared is updated with C2 = C2 + 1 (step 7).
D).

On the other hand, if it is determined in step 74 that the checked elevator car C2 has a direction, the elevator car C1 represented by the variable C1 and the elevator car C2 represented by the variable C2 have the same direction. Is checked (step 75). If the directions of both elevator cars are not the same,
The elevator car to be compared is updated as C2 = C2 + 1 (step 7D). If the directions of the two elevator cars are the same, it is checked whether the floor difference between the positions of the elevator cars represented by the variables C1 and C2 is smaller than a predetermined constant n. (Step 76).

The elevator car C1 and the elevator car C2
Is larger than a constant n, C2 = C2 + 1
Then, the elevator car to be compared is updated (step 7D). Elevator car C1 and elevator car C2
Is smaller than the constant n, it is checked whether the car positions of the elevator car C1 and the elevator car C2 are on the same floor (step 77).

The elevator car C1 and the elevator car C2
If the car positions are on the same floor, it is checked whether the elevator car C1 and the elevator car C2 are stopped (step 78). If the car positions of the elevator car C1 and the elevator car C2 are not at the same floor, the hall call registration information is sent only to the single control device 6 of the elevator car running at the head (step 79). The direction of the car is U
In the P direction, the elevator car is traveling on the upper floor, and in the DOWN direction, it is the elevator car traveling on the lower floor.

When the elevator car C1 and the elevator car C2 are both stopped (including deceleration), the hall call registration information is sent only to the elevator car that has arrived first (Step 7A). If either one of the elevator car C1 and the elevator car C2 is stopped (including deceleration), the hall call registration information is sent only to the running elevator car (step 7).
B). When the elevator car C1 and the elevator car C2 are both running, the hall call registration information is sent only to the elevator car C1 (step 7C).

Next, the elevator car to be compared is updated as C2 = C2 + 1 (step 7D). Next, C
It is determined whether or not 2 is smaller than (the number of elevator cars-1) (step 7E), and if so, the process returns to step 74. When C2 is a value larger than (the number of elevator cars-1) or the same value, C1 = C1 + 1
Is updated as the comparison source (step 7F). And C1 is (the number of elevator cars -1)
It is determined whether the value is smaller (step 7G),
If so, the process returns to step 72, and if C1 is greater than or equal to (the number of elevator cars -1), the process ends.

As described above, the allocation control unit 5 of the group management control device 3 monitors the running state and the stopped state, the running direction, and the car position of each elevator car, and the floor difference of the elevator cars is constant in the same driving direction. When it detects that it is within the range,
Select the elevator car to be stopped for a registered hall call. And the elevator car
The elevator car is sent to the hall call registration unit 4. The hall call registration unit 4 sends the hall call registration status only to the single control device 6 of the elevator car based on the elevator car information to be stopped sent from the assignment control unit 5. This can avoid useless driving in which a plurality of elevator cars stop for the same hall call.

Next, a fifth embodiment of the present invention will be described. FIG. 8 is a flowchart illustrating the operation of the allocation control unit 5 according to the fifth embodiment of the present invention. In the fifth embodiment, when detecting that a car other than the assigned car stops at the hall call occurrence floor, the assignment control unit 5 also sets the time required for the stop as a requirement of the estimated arrival time of the car. It is like that.

In FIG. 8, a variable C1 indicating the elevator car number and a variable t (C1) indicating the estimated arrival time of each elevator car are set as initial settings (step 81). Next, on the scheduled stop floor of the elevator car C1,
It is checked whether there is a car call or a hall call of the elevator car C1 (step 82).

If there is no car call or landing call assigned to the elevator car C1 on the floor at which the elevator car C1 is to be stopped, the estimated arrival time t (C1) of the elevator car C1 is reached.
Then, the travel time, deceleration time, door opening / closing time, and acceleration time until the stop are added to the scheduled stop floor (step 83).

Next, it is checked whether or not the processing of step 82 has been performed for all the planned floors of the elevator car C1 to be stopped (step 84).
Return to If the process of step 82 has been executed for all the stopped floors, C1 is updated to the next elevator car with C1 = C1 + 1 (step 85). Next, the variable C
1 is compared with (the number of elevator cars-1) (step 86). If the variable C1 is small, the process returns to step 82, and if the variable C1 is large or the same, the process ends.

As described above, the assignment control unit 5 of the group management control device 3 compares the assignment information for the hall call with the car information, and determines whether the assigned elevator car and the car call are registered, If it is predicted that the other car will stop at the hall call registration floor, the deceleration time, door opening time, and acceleration time of the elevator car necessary for the stop are reflected in the predicted arrival time. Thereby, a correct expected arrival time can be obtained.

Next, a sixth embodiment of the present invention will be described. FIG. 9 is a flowchart illustrating the operation of the single control device 6 according to the sixth embodiment of the present invention. This sixth
In this embodiment, a floor to be input and a floor not to be input can be selected for a hall call on each floor.

In FIG. 9, a variable h indicating a service floor is set as an initial setting (step 91). The floors to be serviced are sequentially set in this variable h. For example, when each floor of a building from the first floor to the eleventh floor is serviced, 1 is set.
To 11 are sequentially set.

Next, it is checked whether the floor corresponding to the set variable h is a floor call input permitted floor (step 92). This check is performed by a floor call input permission floor BUBBLE FLR preset in the memory of the single control device 6.
This is performed based on (h). FIG. 10 is an explanatory diagram of the hall call input permission table. This hall call input permission table is formed in a rewritable read-only memory of the single controller 6, and "1" is displayed on the floor call input permission floor.
Is set, and “0” is set for floors that are not permitted.

If it is determined in step 92 that the floor is a hall call input permitted floor, the hall call input is referred to (step 9).
3). That is, when there is a hall call on the floor, the hall call is taken in and made valid. On the other hand, if the floor does not allow the floor call input, the floor call input is not referred to regardless of the presence or absence of the hall call, and the floor call of the floor is not taken in.

Next, the variable h is set to h = h + 1, and the variable h is updated to the next floor (step 94). Then, it is checked whether or not the variable h is equal to the number of service floors. If it is not the same, the process returns to the step 92, and if it is the same, the process ends (step 95).

As described above, in the single control unit 6, the hall call registration information sent to each single control unit 6 from the hall call registration unit 4 is compared with the hall call registration information of the floor not registered in the hall call input permission table. Is not referred to, so that the assigned car will respond to the hall call on that floor.

[0062]

As described above, according to the present invention, in the elevator of the group management control configured so that the waiting person at the landing can see the movement of the elevator, the state of the landing call is inputted even in each single control device. When it is detected that the vehicle is likely to pass the hall call, the own car is stopped for the hall call, so that the elevator can be prevented from passing through the hall call registration floor. As a result, it is possible to prevent the passengers at the landing from feeling uncomfortable.
