Data collection method and system of multi-turn encoder, terminal and storage medium

Abstract

The invention provides a data collection method and system of a multi-turn encoder, a terminal and a storage medium. The method comprises the steps that when a zero calibration instruction is received, zero calibration data sent by the encoder is acquired, and outage saving is performed; when the system is powered on, the saved zero calibration data and real-time collected data sent by the encoderin real timeare acquired; actual data values are determined according to the zero calibration data and the real-time collected data; and whether the encoder crosses zero or not is judged according tothe real-time collected data, and if the encoder crosses zero, zero-crossing processing is performed on the actual data values, wherein an initial position, measured by the encoder, of a mechanical device is set to be zero. According to the method, through encoder initial value calibration and zero-crossing processing, it is unnecessary to consider zero correspondence between the encoder and themechanical device during encoder installation, the encoder can be installed under an arbitrary angle; and meanwhile, limitation of the measuring range of the encoder is avoided, the working efficiencyof encoder installation can be remarkably improved, and the accuracy of encoder data collection is ensured.

Description

technical field [0001] The present application relates to the technical field of data acquisition, in particular to a data acquisition method, system, terminal and storage medium of a multi-turn encoder. Background technique [0002] An encoder is a device that converts the angular displacement or linear displacement of mechanical rotation into an electrical signal, and transmits it to the acquisition device through digital quantities. It is a precision measuring device that combines machinery and electronics closely. Encoders are widely used in many aspects such as motors, automobiles, wind power, elevators, and robots. It converts a mechanical geometric displacement into an electronic signal, an electronic pulse signal or a data string through the principle of photoelectricity or electromagnetic principle. Generally, when the sensor is installed, it is necessary to install the zero position of the encoder and the zero position of the mechanical device at the same positio...
