FIG. 1 is a diagram showing a configuration of a car floor landing position correction device according to a first embodiment of the present invention. This car floor landing position correction device is stored in a control panel 8 shown in the above-mentioned drawings. ing. In FIG. 1, parts that are the same as or correspond to those in the conventional example are given the same reference numerals, and descriptions thereof are omitted.

It is designed to store the displacement measurement value of the floor level position at each landing floor, which is generated on the floor level position, and this floor level position is the floor level to be landed on each landing floor as the landing floor information based on the measured value. It is possible to update to the correction position of.

That is, as shown in FIG. 2, in the hall floor information table 23, in order to stop the car corresponding to the landing plate 7 of each hall with the lowest floor as the reference position, as in the conventional example. Each of the halls generated between the floor 6 and the floor of the car 1 and the area 23a for sequentially storing each floor from the lowest floor to the top floor as the floor level position at the time of initial setting of each hall. An area 23b for storing the measured value of the floor level position deviation on the floor is secured.
As for the data of the area 23a, as will be described later, the distance to the landing plate 7 of each landing floor with respect to each landing floor is the deviation of the floor level position actually generated in each landing floor. It is possible to update to the floor level position to be landed, which is corrected based on the amount.

Reference numeral 28 updates the contents of the area 23a of the hall floor information table 23 at the time of initial setting, based on the deviation amount of the floor level position between the floor of the hall and the car floor measured at each hall. This is means for updating the hall floor information table. Then, the car position calculation unit 22, the landing floor information table 23, the remaining distance calculation unit 24, the travel command unit 26, and the travel command table 2
5 and the landing floor information table updating means 28 constitute the traveling control unit 9.

The operation of the car floor landing position correcting apparatus according to the first embodiment constructed as described above will be described. First, the operation of correcting the floor level position and updating the hall floor information table 23 will be described with reference to FIG. FIG.
The landing floor information table 23 by floor-level position correction in the car landing position correction device shown in the first embodiment of the present invention
5 is a flowchart showing an operation procedure for updating the.

When the building contracts due to the secular change after the building is constructed, the facility manager can obtain it by actually measuring the deviation amount of the floor level position generated at each landing floor during the maintenance and inspection of the elevator.

Therefore, in order to record the shift amount of the floor level position measured at each hall floor in the hall floor information table 23, it is sequentially written in the area 23b of the hall floor information table 23 via the hall floor information table updating means 28. . Therefore,
As shown in FIG. 2, in the hall floor information table 23, the floor level position at each hall floor at the time of initial setting as shown in the conventional example is measured in the area 23a, and the floor level position in the area 23b is measured at each hall floor. The shift amount of the floor level position is stored.

Next, the hall floor information table updating means 28.
Is based on the floor level position to be landed at the time of initialization and stored in the areas 23a and 23b of the hall floor information table 23, and the deviation measurement amount of the floor level position at each hall, according to a predetermined software program. Corrected hall floor information of the hall, that is, corrected floor level position data for landing is created.

The corrected floor level position data to be landed is stored in the area 23b of the floor position information table 23 shown in FIG. Are sequentially stored in the area of the address corresponding to each hall. That is, the floor level position data registered at the time of initial setting is updated. In this way, the hall floor information table 23 after the floor level position correction is completed.

It is to be noted that, in addition to storing the updated floor level position for landing on each landing floor in the region 23a, leaving the measured displacement of the floor level position in the region 28b,
This is so that even if a failure occurs in the software program described above, the corrected floor level position for landing can be obtained again.

Since the operation of the elevator operation control device using the position-corrected hall floor information table 23 created as described above is the same as that of the conventional example, description thereof will be omitted.

According to the first embodiment, the car position calculating section for calculating the current position of the car based on the number of revolutions of the elevator hoisting machine, and the floor level position to be landed on each floor of the car are stored. Calculate the remaining distance that the car will travel to the next stop floor based on the floor information table, the car stop target floor input, the output of the car position calculation unit, and the information stored in the floor information table Car landing position correction device including a remaining distance calculation unit, a traveling command table that stores traveling commands corresponding to the remaining distance, and a traveling command unit that extracts traveling commands corresponding to the remaining distance from the traveling command table At, the floor level information for obtaining the floor level position to land on each floor based on the amount of displacement between the floor and the car floor obtained for each floor and updating the contents of the floor information table Equipped with table updating means Therefore, when the car stops at each landing floor, it is possible to obtain the corrected floor level position to be landed, which is the target landing floor information when the car stops at each landing floor. Therefore, even if there is a displacement between the floor of each landing floor and the floor of the car due to contraction of the building, it is possible to eliminate the need to move the landing plate up and down for each landing floor. Therefore, it is possible to easily correct the deviation of the floor level position and reduce the labor of the facility manager.

Example 2. In an elevator installed in a building, the guide rail 10 is displaced with respect to a locking member that locks the guide rail 10 in a hoistway so as to release the influence of the contraction on the guide rail 10 even if the building contracts. Since it is supported by this locking member, the landing plate 7
The amount of change in the displacement of the height position of is lower than the amount of change in the downward movement of the floor 6 and can be actually ignored. Therefore, the displacement of the floor generated at a certain landing floor can be understood as the amount of contraction of the building corresponding to the landing floor.

Generally, the descent of the height position of the floor 6 that occurs on a floor of a building is mainly caused by the weight of the building above the floor. Also, for example, if shrinkage occurs at a uniform rate in the entire building, the floor misalignment that occurs on a given floor is proportional to the number of floors above that floor. It can also be approximated.

Therefore, from the measured value of the positional deviation of the floor generated at a specific landing floor, a calculation formula for determining the amount of positional deviation of the floor occurring on the other floors of the landing of the building is obtained, and another calculation formula is obtained from the calculated expression. You may obtain | require the positional displacement amount of the floor which generate | occur | produces in the hall floor.

In the car landing position correcting apparatus in the second embodiment, the landing floor information table updating means 28 shown in FIG. 2 in the first embodiment is improved. That is, the landing floor information table updating means 28 is adapted to obtain the correction amount of the floor positional deviation occurring in the other landing floors of the building based on the floor positional deviation measurement value at the specific landing floor. There is. As mentioned above,
For example, if shrinkage occurs in the entire building at a uniform rate and the amount of positional displacement of the floor measured on the hth floor of the building is i, the amount of positional displacement k generated on the jth floor is given by equation (1) k = i / h × j ... (1) can be obtained. Therefore, the corrected position on the jth floor can be obtained in the same manner as in the first embodiment based on the floor position displacement amount k on that floor.

Further, the landing floor information table 23 corresponds to the landing floor information table updating means 28 of the present embodiment and is shown in FIG.
The configuration is as shown in. That is, in the landing floor information table 23, an area 23a for storing the distance to the landing plate 7 of each landing floor based on the lowest floor for each landing floor as landing floor information is provided with a specific landing. An area 23b for storing the measured value of the floor displacement measured on the floor, the measured floor, and the number of floors of the building is secured.

As for the data of the area 23a, the distance to the landing plate 7 of each landing floor based on the lowest floor is actually measured for each landing floor when correcting the floor level position, as in the first embodiment. The correction value updated on the basis of the measured value of the positional deviation of the floor that has occurred on the specific landing floor is stored.

The operation of the car floor landing position correcting apparatus according to the first embodiment having the above-described structure will be described. First, the operation of performing the position correction to update the hall floor information table 23 will be described.

When the building contracts due to aging after building, the facility manager pays attention to a specific landing floor during the maintenance and inspection of the elevator, and actually measures the amount of floor displacement generated on the landing floor. Can be obtained.

Therefore, in order to record the measured amount of floor displacement on the floor, the measured floor, and the number of floors of the building in the hall floor information table 23, the hall floor information table updating means 2
9 is sequentially written in the area 23b of the hall floor information table 23 in the same manner as in the first embodiment.

Therefore, as shown in FIG. 3, in the hall floor information table 23, the floor level position at each hall floor at the time of initialization as shown in the above-mentioned conventional example is stored in the area 23a.
The measurement amount of the positional displacement of the floor at the specific landing floor, the measurement floor, and the number of floors of the building are stored in 3b.

Next, the hall floor information table updating means 28.
Is based on the data stored in the areas 23a and 23b,
A floor displacement amount at each landing floor is determined according to a predetermined software program, and the floor level to be landed on each floor is corrected from the displacement amount according to the predetermined software program used in the first embodiment. Find the position. Here, the amount of floor displacement that has occurred at each landing floor can be calculated based on the above equation (1).

The corrected floor level position data for landing includes the measured value of the floor displacement on the measurement floor in the area 23b.
As shown in FIG. 3, the information is sequentially stored in the area of the address in the area 23a of the hall information table 23 corresponding to each hall as shown in FIG. That is, the floor level position data registered at the time of initial setting is updated. In this way, the hall floor information table 23 after the floor level position correction is completed.

In addition to the corrected floor level position for landing and the landing floor information stored in the area 23a, the floor displacement measurement amount measured in the area 23b is recorded and stored in the area 23a. This is to enable the corrected floor level position for landing to be obtained again even when the above software program is changed, for example, when the above equation (1) is changed.

Since the operation of the elevator operation control device using the position-corrected hall floor information table 23 created as described above is the same as that of the first embodiment, its explanation is omitted.

According to the second embodiment, the hall floor information table updating means determines the floors of the halls on each floor based on the amount of displacement between the floor of the hall and the floor of the car, which is obtained on the particular hall. Since the amount of positional deviation from the car floor is calculated and the floor level position of the car on each landing floor to be landed is calculated based on the amount of positional deviation, the floor misalignment of the specific landing floor can be calculated. Based on the measured values, the amount of floor displacement that occurs on the other floors of the building is calculated, and the landing floor information that is the target when the car stops at each floor according to the amount of displacement Since it is possible to obtain the correction position of the floor level to be floored,
Even if the floor of each landing floor and the floor of the car are displaced due to the contraction of the building, it is possible to eliminate the need to move the landing plate up and down for each landing floor. The floor level position to be corrected can be easily corrected, and the labor of the facility manager can be reduced.
