Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control device for performing an operation of counting the number of pulses of a pulse signal generated in synchronization with traveling of an elevator and setting a pulse value at an elevator stop position on each floor.

[0002]

2. Description of the Related Art Generally, an elevator traveling operation is performed automatically by determining the position of the elevator based on a pulse value obtained by counting the number of pulses from a pulse generator. Therefore, when installing the elevator, it is necessary to set the pulse value at the elevator stop position on each floor.
In addition, the elevator stop position must have no level difference between the floor of the landing and the car floor so that passengers getting on and off will not trip, and the accuracy is required to be about 10 to 20 mm. Since the position of the floor of the building is not expected to have sufficient accuracy for landing accuracy of the elevator, it is necessary to measure and store the stop positions of all floors after installing the elevator.

Therefore, the elevator is run from the bottom floor to the top floor to automatically measure the stop position of each floor. That is, the pulse value when each floor stop position switch installed at each floor stop position is turned on by traveling of the elevator is read and stored.

In this case, when the speed of the elevator is high, a measurement error occurs due to a delay in the software processing for reading the ON of each floor stop position switch, and therefore the elevator needs to run at a low speed. Moreover, since it is not possible to know where the elevator is located until the pulse value is set, the elevator is always pulled back to the lowest floor and then run toward the highest floor.

Since the pulse value is not set even when the vehicle is pulled back to the lowest floor, the position of the lowest floor, which is the terminal floor, cannot be grasped. There is.

[0006]

However, since the number of high-rise buildings has increased in recent years, it takes a lot of time to set the pulse value when traveling at a low speed as in the past. I will end up. In addition, if the position of the elevator after installation is near the top floor,
Since it is necessary to pull back to the lowest floor to set the pulse value, double the time is required. The worker cannot wait for any time while the pulse value is being set, so he / she simply waits.

The object of the present invention is to shorten the working time,
Moreover, it is an object of the present invention to provide an elevator control device capable of accurately setting the pulse value at the stop position on each floor.

[0008]

An elevator control apparatus according to the invention of claim 1 counts the number of pulses of a pulse signal generated in synchronization with the traveling of an elevator to obtain a pulse value at an elevator stop position of each floor.

The pulse value of the elevator stop position of each floor stored in the storage unit is corrected and calculated and stored in the storage unit. As a result, the delay of the reading process of the floor position setting means can be corrected, so that the pulse value at the stop position of each floor can be accurately set even when the elevator is traveling at a high speed. Therefore, the working time can be shortened, and the pulse value at the stop position on each floor can be accurately set.

In the elevator controller according to the second aspect of the present invention, the speed pattern switching means slows the traveling speed of the elevator when the elevator is in each floor stop position zone and the traveling speed of the elevator when it is outside each floor stop position zone. Speed up. The floor position setting means detects the elevator stop position of each floor when the traveling speed of the elevator is slow, and stores the pulse value read by each floor position setting means in the storage unit in association with the elevator stop position of each floor. . Then, when the floor position setting means is outside each floor stop position zone in which the elevator stop position of each floor is not detected, the traveling speed of the elevator is high. Therefore, the working time can be shortened, and the pulse value at the stop position on each floor can be accurately set.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. FIG. 1 is a block configuration diagram of an elevator control device according to an embodiment of the present invention.

The pulse generator 1 generates a pulse signal each time it travels a certain distance in accordance with the movement of the elevator 2, and a pulse signal from the pulse generator 3 during upward operation. It is composed of a pulse counter 4 that counts the pulses that are added up and subtracted when the operation is in the downward direction.

Floor stop position switches 5a to 5n are provided at the elevator stop positions of the respective floors, and an operation signal is output when the elevator 2 comes to the position of the floor stop position switches 5a to 5n. Also, the floor position stop switch 5a-
Outside the 5n, stop position zone detection means 6a to 6n are installed at upper and lower positions that are wider than the elevator stop position. The stop position zone detection means 6a to 6n detect that the elevator 2 has come within a certain distance of the elevator stop position. In addition, terminal floor zone detection switches 7a and 7b are provided on the lowermost floor and the uppermost floor, and it is detected that the terminal floor zone detection switches 7a and 7b are within a certain distance from the position of the lowermost floor or the uppermost floor. To do.

The operation control unit 8 controls the operation of the elevator. For example, when the elevator is installed, the elevator is caused to travel from the lowest floor to the highest floor, or from the highest floor to the lowest floor, and the elevator travels. The number of pulses of the pulse signal from the pulse generator 1 generated in synchronism with the above is counted, and the operation of setting the pulse value at the elevator stop position of each floor is performed.

The start selecting means 9 is for selecting the lowest floor or the highest floor as the operation start floor when starting the operation for setting the pulse value of the elevator stop position of each floor. When it is selected to drive from the lower floor to the uppermost floor, the traveling control means 10 causes the elevator 2 to temporarily travel from the current elevator position to the lowermost floor, and then travels from the lowermost floor to the uppermost floor.

The floor position setting means 11 operates at a predetermined cycle during the traveling period of the elevator 2, reads the pulse value of the pulse generator 1 when each floor stop position switch 5a-5n is in an operating state, The pulse value is stored in the storage unit 12 in association with the elevator stop position of each floor.

The speed pattern switching means 13 is for switching the traveling speed pattern of the elevator, and the floor position setting means 11 is in the vicinity of the elevator stop position so that the floor position setting means 11 can properly read the pulse value at each floor stop position switch 5a-5n. Then, the traveling speed of the elevator 2 is reduced, and the traveling speed is increased in other regions.

That is, the speed pattern switching means 13 is
Based on the detection signals from the stop position zone detection means 6a to 6n, the position of the elevator 2 determines whether the position is inside or outside each floor stop position zone, and when the position of the elevator 2 is within each floor stop position zone, the traveling speed of the elevator 2 is slowed. Then, the detection of the operation signals of the floor position stop switches 5a to 5n by the floor position setting means 13 is ensured. On the other hand, when it is outside the stop position zone on each floor, the traveling speed of the elevator 2 is increased. Further, when the operation signals of the end floor zone detection switches 7a and 7b are input, it is near the bottom floor or the top floor, so that the speed of the elevator 2 is slowed in this case as well.

Next, the pulse value correction means 14 corrects the delay of the reading process of the floor position setting means 11. That is, the pulse value read by the floor position setting means 11 immediately before the floor stop position switches 5a to 5n are activated and the floor position setting means 11 immediately after the floor stop position switches 5a to 5n are activated. The pulse value at the elevator stop position of each floor stored in the storage unit 12 is corrected and calculated based on the pulse value read by the. Then, the result of the correction calculation is stored in the storage unit 12 as a pulse value at each floor stop position switch 5a to 5n.

FIG. 2 is an explanatory diagram of the correction calculation contents in the pulse value correcting means 14 in the embodiment of the present invention.

The floor position setting means 11 is activated at a constant cycle for software processing, and has a cycle longer than the cycle of the pulse value input from the pulse generator 1. The higher the traveling speed of the elevator 2, the smaller the cycle of the pulse value input from the pulse generator 1.

Now, at the time point t1, the floor stop position switch 5
If i is turned on and is in the operating state, the pulse value at the time t1 when the floor stop position switch is turned on is 0202h, but at this time, the floor position setting means 11 is not activated and the pulse value is 0203h. Has started. That is, the software processing of the floor position setting means 11 is delayed due to the size of the operation cycle of the floor position setting means 11 and the high traveling speed of the elevator, and this causes an error in the detected pulse value. When the traveling speed of the elevator 2 increases,
As a result, the pulses are counted faster and the error increases.

In order to correct this error, the pulse value correcting means 14 averages the pulse value 0201h immediately before the floor stop position switch 5i is turned on and the pulse value 0203h when it is turned on. And set as the actual pulse value.

As a result, even if the traveling speed of the elevator 2 is increased, it is possible to correct the error of the pulse value due to the delay of the software processing in the floor position setting means 11.
It is possible to increase the speed of the elevator 2 in the automatic driving operation for setting the pulse value. Therefore, since the automatic traveling operation for setting the pulse value can be completed in a short time, the working time can be shortened.

FIG. 3 is an explanatory diagram in the case where the traveling speed of the elevator 2 is reduced near the elevator stop position by the speed pattern switching means 13. Now, at time t1, it is assumed that it is detected by the stop position zone detection means 6j that the elevator 2 is input near the elevator stop position. In this case, the speed pattern switching means 13 reduces the traveling speed of the elevator to a speed at which the pulse value can be accurately set, and the time t when the input from the stop position zone detection means 6j disappears.
During the time T1 until 2, the elevator 2 is driven at a low speed. During this time T1, the floor stop position switch 5j is turned on. Since the elevator 2 is operated at a low speed during the operation time T2 of the floor stop position switch 5j, the period of the pulse value from the pulse generator 1 becomes large and the detection error in the floor position setting means 11 becomes small. .

In this way, the traveling speed of the elevator is switched between two stages so that the elevator can travel. As a result, it is possible to shorten the time of the automatic driving operation particularly when setting the pulse value of the high-rise floor service elevator installed in the high-rise building. For example, in the case of a high-rise building, two types of elevators, a low-rise service elevator and a high-rise service elevator, may be installed, and the high-rise elevator is configured to pass the floor where the low-rise elevator stops. There is. In this case, since the floor stop position switch 5j is not installed during a certain section through which the high floor elevator passes, it is not necessary to drive at a low speed during that period. In such a case, since the elevator 2 can be moved at a high speed, it is possible to shorten the time of the automatic traveling operation for setting the pulse value.

In FIG. 4, the speed pattern switching means 13 causes the elevator 2 to move near the terminal floor, the top floor or the bottom floor.
It is explanatory drawing in the case of reducing the traveling speed of. Now, assuming that the operation signals of the end floor zone detection switches 7a and 7b are input at time t1, the speed pattern switching means 13
Reduce the speed of elevator 2 to a speed at which it can be safely stopped. Therefore, by increasing the speed of the automatic traveling operation for setting the pulse value, it is possible to prevent the vehicle from traveling to the terminal floor at the same speed and stop suddenly, and to stop safely.

Next, when the automatic traveling operation for setting the pulse value is started, the starting floor is always started from the lowest floor in the prior art, but in the present invention, the starting floor is selected by the start floor selecting means 9 according to the judgment of the operator. Switch.

After installation of the elevator, the elevator 2 is not always located near the bottom floor. After the elevator installation, if the elevator 2 is near the top floor, move it to the top floor. In this way, by selecting whether the current position of the elevator 2 is closest to the bottom floor or the top floor, it becomes unnecessary to drive to the bottom floor at low speed, and the automatic traveling operation for setting the pulse value is started. The time to do is shortened.

[0035]

As described above, according to the present invention, of the elevator adjusting work time in a high-rise building, the time for setting the pulse value can be significantly shortened, and the waiting time of the worker during that time can be shortened. . Further, even if the traveling speed of the elevator is increased, the pulse value can be set accurately.
