Hereinafter, a control device and a control method of an elevator according to the present invention will be described with reference to drawings according to each embodiment. In addition, in each embodiment, the same or equivalent part is denoted by the same reference numeral, and overlapping descriptions are omitted.

Embodiment 1.

1 is a diagram schematically showing the overall configuration of an elevator control device according to Embodiment 1 of the present invention. In the elevator, an elevator car 1 for passengers to ride on one end of the main rope 2 and a counterweight 3 are provided on the other end. The main rope 2 is caught by the hoisting machine 4, and the main car 2 is raised or lowered by the hoisting machine 4 to lift and lower the elevator car 1 and the counterweight 3 in opposite directions.

The governor 5 is provided in the car 1. The governor 5 is composed of a loop-shaped governor rope 5a in which a car 1 is fixed to a part, and an upper and lower governor sheave 5b on which the governor rope 5a is applied. The governor 5 is provided with a rotation speed detector 6 that detects a rotation speed made of, for example, an encoder or the like, and the rotation speed NRO is output. The rotation speed detector 6 may be provided in the traction machine 4 as indicated by a broken line. In addition, the rotation speed detector 6 is not shown in other drawings of the present application.

Inside the hoistway, an implantation plate 7 is provided at positions corresponding to the implantation zones on each floor. The implantation plate 7 may be provided in multiple places on each floor, such as a door zone which is a zone that allows door opening and closing, a relevel zone that allows releveling, and the like.

The implantation plate detector 8 is installed in the car 1 to detect the implantation plate 7. When the implantation plate 7 is provided in a plurality of types, such as a door zone, a relevel zone allowing releveling, an implantation plate detector 8 is provided for each type. The elevator car 1 with the implantation plate detector 8 moves to come to a position equivalent to the implantation plate 7, and the implantation plate detector 8 faces the implantation plate 7, so that the implantation plate detector ( 8) detects the implantation plate 7 and outputs an implantation plate detection signal PDS. The implant plate detector 8 detects one of both ends along the traveling direction of the car 1 of each implant plate 7, as described later, and counts the number of revolutions NRO from the revolution detector 6 It becomes one measurement point.

The control processing device 9 according to the first embodiment of the present invention includes a measurement processing unit 10, a storage unit 11, and a driving control unit 12.

The control processing device 9 can be configured with, for example, a computer 100 showing a schematic configuration in FIG. 9. Input/output is performed through the interface 101. In the memory 103, information and data necessary for programs and processes of various functions represented by function blocks for control described later, and the like are stored in advance, and further processing results and the like are stored. The processor 102 performs arithmetic processing on signals input through the interface 101 according to various programs, information, and data stored in the memory 103 to output processing results through the interface 101, or necessary The processing process and processing results are stored in the memory 103. For example, various functions represented by blocks described later of the measurement processing unit 10 and the drive control unit 12 in FIG. 1 are stored in the memory 103 as a program. Then, the storage unit 11 corresponds to the memory 103.

In addition, the control processing device 9 can also be constituted by one or a plurality of digital circuits that perform various functions represented by blocks described later of the measurement processing unit 10 and the drive control unit 12.

The measurement processing unit 10 counts the rotational speed NRO from the rotational speed detector 6 by the measurement command DEC from the drive control unit 12, and according to the implantation plate detection signal PDS obtained from the implantation plate detector 8 The count value of the rotational speed NRO is measured at the timing of detecting the escape from the implantation plate 7 or entering the implantation plate 7. Then, by calculating the difference in count values for the implanted plates 7 on different layers, for example, adjacent layers, the floor height is calculated.

The floor height data FHD calculated by the measurement processing unit 10 is stored in the storage unit 11. In addition, although not directly related to the present invention, the driving control unit 12, based on the floor height data stored in the storage unit 11, when performing the floor control of the elevator car 1 to the stationary floor after learning the floor height, , By outputting the control command COC to the hoisting machine 4, the idea of controlling the car 1 to the floor requested by the car call, the platform call, etc. is performed.

The driving control unit 12 causes the elevator car 1 to perform a floor-level learning operation when learning the floor height, and moves the car 1 to a first speed V1 at a rated speed, from the lowest floor to the top floor. Thereafter, the drive control unit 12 drives the car 1 at a second speed V2 lower than the first speed V1 in order to obtain the floor height of the lowest floor. As described later in FIG. 3, the second speed V2 accelerates from speed 0 to second speed V2 from the lowest floor, and the car 1 is the lowermost floor plate 7 from the time when the speed becomes the second speed V2. Time until exiting, and more specifically, from the time when the speed reaches the second speed V2 until the implant plate detector 8 of the car 1 passes through the end of the implant plate 7 of the lowest floor. The time length of is determined so that a preset time length is secured.

The preset length of time is a natural frequency and a damping coefficient from the mechanical specifications of the elevator's mechanical mechanism including the car 1, the main rope 2, the counterweight 3, the hoisting machine 4, and the governor 5 The value is greater than the length of time during which the vibration is sufficiently attenuated. The imbalance of mechanical specifications is also taken into consideration, and it is sufficient to determine the length of time to attenuate by including sufficient margin.

FIG. 2 is a view for explaining the control of traveling in a car during floor height learning by control of the control processing device 9 according to the first embodiment of the present invention. 2 (a) is a schematic diagram of the elevator, (b) is a measurement point, (c) is the speed of the car 1, (d) is the stretch amount of the governor rope 5a, (e) is the main rope (2) ). The vertical axis represents the position of the car corresponding to (a).

The drive control unit 12 drives the car 1 at a first speed V1 and travels from the lowest floor to the upper floor. In the floor height learning, the end portion of the implantation plate 7 indicated by a black circle in Fig. 2B is measured.

In the case of high lift, when accelerating from the lowermost floor, as the car 1 is accelerating at the upper end of the lowermost implanted plate 7, as shown in Figs. 2(d) and (e). The stretch amount of the governor rope 5a or the main rope 2 becomes large. Therefore, the error by expansion and contraction overlaps with the rotation count count value at the time of the detection of the escape from the upper end of the implantation plate 7 in the measurement processing part 10, and this becomes an error in height learning.

In addition, the size of the rope stretching of the governor rope 5a or the main rope 2 is proportional to the size of the acceleration/deceleration. When the magnitudes of the acceleration and deceleration are the same, when deceleration of the car 1 to the lowest floor, the rope stretching direction of the governor rope 5a or the main rope 2 is the same, but the rope stretching direction is changed.

In the case of the upper layer, the mechanical system becomes high rigidity, the amount of expansion and contraction of the rope becomes small, and the overlapping error is often negligible as the height learning.

FIG. 3 is a view for explaining the driving control of a car for measuring the floor height of the lowest floor during floor height learning by control of the control processing device 9 according to the first embodiment of the present invention. The driving control unit 12 drives the car 1 at a second speed V2 lower than the first speed V1 with respect to the floor height of the lowest floor. 3(a) is a schematic diagram of the elevator, (b) is a measurement point, (c) is the speed of the car 1, (d) is the stretch amount of the governor rope 5a, and (e) is the main rope 2 ). The vertical axis represents the position of the car corresponding to (a).

As shown in Fig. 3, since the acceleration time is short at the second speed V2, the amount of expansion and contraction of the governor rope 5a in (d) during acceleration and the amount of expansion and contraction of the main rope 2 in (e) are large, but (b At the measurement point of the lowermost implanted plate 7 indicated by a black circle in ), the car 1 is traveling at a constant speed. In addition, after the acceleration has reached the second speed V2 after completion of the acceleration, it is shown in correspondence to the position of the car in FIG. 3 until the implant plate detector 8 of the car 1 escapes from the top of the car plate 7 The time length T is secured for a set time length, and the vibration generated when the acceleration is changed is attenuated sufficiently. Therefore, the error caused by the expansion/contraction of the main rope 2 or the governor rope 5a does not overlap with the rotation count count value at the time of measuring the position of the implant plate 7 in the measurement processing unit 10.

In the run shown in Fig. 3, measurements are made at the lowest layer and the next adjacent layer.

4 shows an example of the internal configuration of the measurement processing unit 10 according to Embodiment 1 of the present invention. The measurement processing unit 10 is provided with a floor height measurement unit 10a, an error calculation unit 10b, and a correction unit 10d. Further, although the storage unit 11 is shown as being used in the control processing apparatus 9, for example, a dedicated storage area of the measurement processing unit 10 is set in the storage unit 11, or a separate memory is set. You may prepare.

The floor height measurement part 10a counts the rotation speed NRO from the rotation speed detector 6 according to the measurement command DEC from the drive control part 12, and the car 1 and more specifically, the implantation plate detector 8 ) At the timing of the detection of the exit from the front end of the car 1 of the implanted plate 7 from the front end, or the detection of the entrance of the car 1 to the front end of the car 1 Count the number of revolutions. Subsequently, by calculating the difference between the count values of the bottom layer and the adjacent layer, the floor height of the bottom layer is calculated. Here, the floor height LFH1 of the lowest layer at the first speed V1 and the floor height LFH2 of the lowest layer at the second speed V2 are both output as the floor height data LFHD.

The error calculating section 10b, according to the calculation command ACO from the floor measuring section 10a, similarly outputs the floor height LFH1 of the lowest layer at the first speed V1 and the floor height LFH2 of the lowest layer at the second speed output from the floor height measuring section 10a. The difference between is calculated as a correction amount (extension amount) (ΔLFH = LFH2-LFH1) and stored in the storage unit 11.

The correction unit 10d uses the correction amount ΔLFH stored in the storage unit 11 in accordance with the correction command CCO from the floor height measurement unit 10a to obtain the lowest floor height LFH1 obtained at the first speed V1 included in the correction command CCO. Is corrected (LFH1-ΔLFH) by the correction amount ΔLFH.

The floor height measuring unit 10a converts the floor height of the lowest layer among the floor height data to a corrected floor height and stores it in the storage unit 11 as the floor height data FHD.

The effects according to the above configuration are summarized.

When learning the floor height, the driving control unit 12 controls the car 1 to travel at a constant speed at a second speed V2 lower than the first speed V1 from the lowest floor to the adjacent floor. For this reason, since the driving at the second speed V2 is only for the floor height of the lowest floor, it is possible to make the rope expansion and contraction difficult to be affected by the large lower floor, and to shorten the learning time.

In addition, the second speed V2 is determined such that the set time length is secured from the time when the speed is accelerated to the second speed and the implantation plate detector 8 of the car exits the implantation plate 7. do. For this reason, it is possible to attenuate the vibration of the car by the rope stretching at the end of the acceleration until the car 1 exits the implantation plate 7, and the accuracy of floor height learning can be improved.

The measurement processing unit 10 includes a correction unit 10d that corrects errors when re-learning at the first speed V1. For this reason, by calculating and storing the correction amount, it is only necessary to run at the first speed V1 for the adjusted height, and it is no longer necessary to run the car at the second speed V2 for the floor height correction at the lowest level.

Embodiment 2.

5 is a diagram schematically showing the overall configuration of an elevator control device according to Embodiment 2 of the present invention.

The measurement processing unit 10aa counts the rotational speed NRO of the rotational speed detector 6 by the measurement command DEC from the drive control unit 12aa, and detects the escape from the implantation plate 7 of the car 1, Alternatively, the count value of the number of revolutions at the timing of detection of entry into the implantation plate 7 is measured, and the floor height is calculated and stored in the storage unit 11. Incidentally, the internal configuration of the measurement processing section 10aa is, for example, as shown in Fig. 4 of Embodiment 1, but the error calculation section 10b, correction section 10d, and storage section 11 are not used.

The driving control unit 12aa first accelerates the lowermost floor to the second speed V2 lower than the first speed V1, which is the rated speed described above, to drive the car 1. Thereafter, the elevator car 1 is re-accelerated in a place where there is no implantation plate 7, that is, where the implantation plate detector 8 of the elevator car 1 does not face the implantation plate 7, and is removed to the top floor. The elevator car 1 is driven by one speed V1. The second speed is a preset time length from the time when the speed is accelerated to the second speed and the time from the top of the top plate 7 to the top plate detector 8 of the car 1 is set. It is decided to be secured. The preferred set time length is the same as in the above embodiment.

FIG. 6 is a view for explaining the control of traveling in a car during floor height learning by control of the control processing device 9 according to the second embodiment of the present invention. 6(a) to 6(e) show the same ones as in FIGS. 2 and 3 of the first embodiment.

The driving control unit 12aa causes the car 1 to run at a second speed V2 lower than the first speed V1 with respect to the lowermost floor. As shown in Fig. 6, since the acceleration time is short at the second speed V2, the car 1 is at a constant speed at the measurement point of the lowermost implanted plate 7 indicated by the black circle in Fig. 6B. To the road. In addition, the set time length is secured from the time when the speed reaches the second speed V2 after the completion of the acceleration until the implant plate detector 8 of the car 1 escapes from the top of the implant plate 7 Therefore, the vibration generated when the acceleration is changed is attenuated sufficiently.

After the implantation plate detector 8 escapes the implantation plate 7 of the lowest layer, the car 1 is reaccelerated to the first speed V1. The distance from the lowermost floor to the next adjacent floor is sufficiently far away, and at the measurement point of the implantation plate 7 on the lower floor next to the lower floor indicated by a black circle in Fig. 6B, the car 1 It runs at a constant speed of 1 speed V1.

Therefore, the error by expansion/contraction of the main rope 2 or the governor rope 5a does not overlap with the rotation count count at the time of measuring the position of the implant plate 7 in the measurement processing unit 10aa.

In the case of the upper layer, since the mechanical system becomes highly rigid, the amount of stretching of the rope becomes small, and the overlapping error is often negligible as the height learning. Therefore, here, the elevator car 1 does not pass the implantation plate 7 at the top floor side, especially at a constant speed.

The effects according to the above configuration are summarized.

When learning the floor height, the driving control unit 12aa moves the lowermost floor of the elevator car 1 at a second speed V2 lower than the first speed V1, and then the implanted plate detector 8 of the car 1 is implanted plate. The car 1 is re-accelerated in a place not facing (7), and is driven to the top floor by the first speed V1. This eliminates the need to individually study the lowest floor height.

In addition, the second speed V2 is such that the time length from the point when the speed becomes the second speed V2 after the completion of the acceleration until the implantation plate detector 8 leaves the upper end of the implantation plate 7 is secured. It is decided. For this reason, the vibration of the cage|basket|car by the extension of the governor rope or the main rope at the end of acceleration can be attenuated until the cage|basket|car 1 exits the implantation plate 7, and the accuracy of floor height learning can be improved.

Embodiment 3.

7 is a diagram schematically showing the overall configuration of an elevator control device according to Embodiment 3 of the present invention.

The measurement processing unit 10bb is the same as the measurement processing unit 10aa in FIG. 5 of the second embodiment.

The driving control unit 12bb is provided to the first speed V1, which is the rated speed, for each section in which the implantation plate detector 8 of the elevator car 1 does not face the implantation plate 7 without the implantation plate 7. , Re-accelerate the car 1 step by step. In addition, after acceleration for each acceleration section, the time length from the implant plate 7 to the exit or entry of the implant plate detector 8 is secured so that the set time length is secured, so that vibration generated when the acceleration is changed is sufficiently damped. do. The preferred set time length is the same as in the above embodiment.

FIG. 8 is a view for explaining the driving control of a car during floor height learning by control of the control processing device 9 according to the third embodiment of the present invention.

The driving control unit 12bb travels to the lowermost layer at a second speed V2 that is lower than the first speed V1. As shown in Fig. 8, since the acceleration time is short at the second speed V2, the car 1 is at a constant speed at the measurement point of the lowermost implanted plate 7 shown by the black circle in Fig. 8B. To the road. In addition, the time length Ta from the time when the speed becomes the second speed after the completion of the acceleration until the implantation plate detector 8 of the car 1 escapes from the top of the implantation plate 7 is secured with a set time length Ta Therefore, the vibration generated when the acceleration changes is sufficiently damped.

After escaping the bottom-end implantation plate 7, the car 1 is re-accelerated to a third speed V3 (V1>V3>V2) lower than the first speed V1 and higher than the second speed V2. As shown in Fig. 8, the acceleration time to the third speed V3 is short. In addition, the time length Tb from the time when the speed reaches the third speed V3 after the end of the acceleration until the car 1 enters the implantation plate 7 of the adjacent floor is secured, and the set time length is secured, thus changing the acceleration. The vibration generated at the time is also sufficiently damped. Therefore, in the measurement point of the implantation plate 7 in the next adjacent layer of the lowermost layer indicated by a black circle in Fig. 8B, the car 1 runs at a constant speed.

Therefore, the error by expansion/contraction of the main rope 2 or the governor rope 5a does not overlap with the rotation count count at the time of measuring the position of the implant plate 7 in the measurement processing unit 10bb. Subsequently, the re-acceleration is carried out step by step, up to the first speed V1, for each section without the implantation plate 7, so that the errors do not overlap.

In the case of the upper layer, since the mechanical system becomes highly rigid, the amount of stretching of the rope becomes small, and the overlapping error is often negligible as the height learning. Therefore, here, the uppermost layer side does not pass through the implantation plate 7 at a constant speed.

The effects according to the above configuration are summarized.

During the floor height learning, the drive control unit 12bb re-accelerates step by step up to the first speed V1 for each section without the implantation plate 7. For this reason, even when the floor height is shortened in, for example, a two-door elevator car, it is difficult to be influenced by rope expansion and contraction due to acceleration, and further reduction in learning time can be achieved.

In addition, after acceleration for each section without the implantation plate 7, the length of time until the exit or entry of the implantation plate 7 of the car 1 is controlled such that a set time length is secured. For this reason, it is possible to attenuate the vibration of the car by the rope stretching at the end of the acceleration until the car 1 exits the implantation plate 7, and the accuracy of floor height learning can be improved.

In addition, the implantation plate 7 and the implantation plate detector 8 detect a lamellar plate 7 provided at a laminar position in a hoistway with the implantation plate detector 8 provided in the car 1 and detect a lamellar position. The position detection units 7 and 8 are configured.

In addition, the rotational speed detector 6 constitutes a moving distance detecting unit 6 for detecting the moving distance of the moving car based on the movement of the governor rope 5a or the main rope 2.

Then, the measurement processing unit 10 measures the floor height by the detected floor position and the moving distance of the car during the floor height learning operation.

In addition, even when the rotational speed detector 6 is mounted on the hoisting machine 4, as shown in Figs. 2, 3, 6, and 8, there is expansion and contraction of the main rope 2, so the embodiment of the present invention By applying 1, 2, and 3, it is possible to similarly expect high-precision layer height learning.

In addition, in each of the above embodiments, the elevator car 1 was raised from the lowest floor to the uppermost floor during floor height learning, but it is also possible to carry out the operation of lowering the elevator car 1 from the uppermost floor to the lowest floor.

[Possibility of industrial use]

Measure and store the floor height based on the detected floor position and the moving distance of the car,
The distance from the lowest floor to the next adjacent floor is driven by the elevator car at a constant speed at a second speed lower than the rated first speed,
Obtain and store the error between the floor height of the lowest floor and the floor height measured by driving the car at the second speed, and the floor height measured by running at the first speed.
When re-learning at the first speed, an elevator control method is performed to correct the error. delete
