High-reliability moving positioning control method, device and system

Abstract

The invention relates to a high-reliability moving positioning control system. The high-reliability moving positioning control system comprises a high-reliability moving positioning control device andan induction block, wherein the high-reliability moving positioning control device comprises a controller, an encoder and two sensors, the controller is a computer controller, the encoder and the twosensors are connected with the controller in a matching way, the encoder, the two sensors and the controller are fixed on a trolley in a matching way, the two sensors are arranged in a travelling direction of the trolley and are adjacent to each other in a forward and backward direction, the two sensors are matched with the induction block arranged at a parking position, and the encoder is installed with the trolley in a matching way and is used for detecting the range of the trolley. The two sensors, the induction block and the encoder are integrally used, a fault of key positioning equipment can be detected in real time, and a system working error caused by positioning mistake is prevented.

Description

technical field [0001] The invention relates to electromechanical devices, in particular to a high-reliability motion positioning control method, device and system. Background technique [0002] Existing mobile equipment such as metallurgy and chemical industry, warehousing and logistics, feed aquaculture, overhead cranes, door cranes, etc., especially mobile vehicles that require unattended, long-distance, multi-station, high-precision, high-precision, and reliable positioning control Most automatic positioning control systems use travel switches and encoder counts as position judgments to control positioning. The encoders are installed in different ways, some are installed on the wheel shaft, some are installed on the drive motor shaft, and some are installed separately. rack and pinion.

AI Technical Summary

Problems solved by technology

[0003] The problem is that when the trolley travels longitudinally, there will be lateral movement, coupled with insufficient track level, there is a left-right height deviation, there are sundries on the track and wheel rim, etc., resulting in insufficient positioning accuracy and excessive positioning error

If the travel switch is used alone to judge whether the trolley is in place, due to the misoperation, interference and damage of the switch signal, it may cause misalignment, wrong material loading, and accidents.

The commonly used ones are to install an encoder on the wheel shaft, or install an encoder on the drive motor shaft, and judge whether the trolley is moving in place by the number of pulses of the encoder; the problems that are likely to occur are: the encoder is loose, and the wheel rim and track The debris on the road causes the circumference of the traveling wheel to change, which eventually causes positioning deviation

The inaccurate positioning of the mobile trolley will eventually cause positioning deviation, resulting in misplaced stops, wrong materials, and even product scrapping, or even quality and safety accidents.
