Abstract

An incremental absolute encoder detection device, comprising an encoder installation platform, a control board, and a rotary drag device, the encoder installation platform has a built-in AC / DC power supply, a touch screen and a control board that can be installed, Frame structure of rotary drive unit and encoder fixing flange. The control board is installed on the inner side of the encoder installation platform to complete the closed-loop control of the rotary drag device, touch screen display and encoder detection logic. The rotary dragging device is a dual-shaft DC motor with a main encoder, which is used to drive the detected encoder to rotate synchronously with the main encoder, and is installed at the inner center of the encoder installation platform. The present invention collects the incremental signal and position value of the encoder under test and performs real-time verification with the feedback value of the main encoder, and can accurately capture the state of the feedback value of the encoder.

Description

technical field [0001] The invention belongs to the technical field of wind power, and in particular relates to a detection device for an incremental absolute value encoder. Background technique [0002] With the further popularization of clean energy, more and more wind turbines are put into use. The pitch control system is an important device for the control and protection of wind turbines above the megawatt level, and it is the main braking system for wind turbines to stop. The pitch control system is a three-closed-loop motion control based on position, speed, and torque. In order to complete the above-mentioned closed-loop control of position and speed, most manufacturers use incremental absolute encoders installed inside the pitch motor for position control. And the way of speed signal acquisition. [0003] To sum up the above functions, the wind power pitch system installs an incremental absolute value encoder inside the pitch motor, and the encoder feeds back real-...
