Example Embodiment

[0035] The present invention will be further described below in conjunction with the drawings.

[0036] Attached figure 1 It is a schematic diagram of the composition of a wheel-rail large-scale turntable position control system. A wheel-rail type large-scale turntable position control system includes a position controller (the position controller can be implemented with a controller such as PLC, industrial control computer or DSP. This example is used PLC as the host computer), angle detection device, first motor driver, second motor driver, and third motor driver (Note: the selected first motor driver, second motor driver, and third motor driver must have a field bus interface), The first transmission chain, the second transmission chain, and the third transmission chain (Note: the number of motor drives and transmission chains can be determined according to the actual drive power requirements of the turntable); the position controller is connected to the first motor driver and ...

Abstract

The invention discloses a wheel-track type large rotary table position control system and a control method thereof. The wheel-track type large rotary table position control system comprises a rotary table, a wheel-track orbit, motor drivers, a transmission chain, an angle detection device and a position controller, each transmission chain comprises a motor, a speed reducer and a drive wheel, the wheel-track orbit is arranged at the bottom of the rotary table, the drive wheel and wheel-track orbit drive the rotary table to rotate through friction transmission, the drive wheel and a driven wheel are used for supporting the rotary table, the position controller is connected with a plurality of motor drivers, the motor drives the corresponding drive wheel to rotate through the speed reducer, and the angle detection device is used for measuring the rotary angle of the rotary table. The wheel-track type large rotary table position control system uses several circles of absolute value encoders as the angle sensor of the position control system to detect the rotary angle of the driven wheel in real time, the rotary table angle is indirectly measured to control the rotary table position through calculation, and moreover, a zero calibration switch is arranged on the rotary circumference of the wheel-track type rotary table to calibrate the rotary table angle detection resolution ratio to improve the angle detection precision.

Description

technical field [0001] The invention relates to a position control system and a control method of a wheel-rail type large-scale turntable, and belongs to the technical field of position control of a large-scale wheel-rail type turntable. Background technique [0002] When the caliber of the rotary turntable is large, it is an inevitable choice to adopt the wheel-rail drive mode. The difference between the wheel-rail turntable and the ordinary turntable is mainly reflected in the support and transmission mode. The support of the wheel-rail turntable adopts the wheel-rail track and the rollers running on the track (including the driving wheel and the driven wheel); in the transmission mode, the wheel-rail type The antenna pedestal is driven by friction between the roller and the track; it replaces the traditional rack and pinion drive. At present, with the continuous development of application requirements, this technology is more and more widely used in fields such as large ...
