A data acquisition method, system terminal and storage medium of a multi-turn encoder provided by the present application, the method comprising: when receiving a zero calibration instruction, acquiring the zero calibration data sent by the encoder and saving it after power-off; When the system is powered on, obtain the saved zero calibration data and the real-time acquisition data sent by the encoder in real time; determine the actual data value according to the zero calibration data and real-time acquisition data; judge whether the encoder crosses zero according to the real-time acquisition data, and if so, then Perform zero-crossing processing on the actual data value; among them, the initial position of the mechanical device measured by the encoder is set to zero; this application uses the initial value calibration and zero-crossing processing of the encoder, so that the encoder does not need to consider the encoder and the mechanical device when installing the encoder. The zero position of the device corresponds, so that the encoder can be installed at any angle without being limited by the range of the encoder, which can significantly improve the work efficiency of encoder installation and ensure the accuracy of encoder data collection.
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...
