Abstract

The invention provides a detecting system for an incremental encoder. The detecting system comprises an upper computer, a controller, a subdivision driver, a stepping motor, a speed reducing device and an encoder to be detected. The upper computer is used for transmitting a signal including angular displacement to the controller, comparing the angular displacement and actual rotary angular displacement of the encoder to be detected and judging the accuracy of the encoder to be detected. The controller is used for converting the angular displacement into the number n of corresponding pulses, transmitting a pulse signal to the subdivision driver and transmitting the signal including the angular displacement to the upper computer. The subdivision driver is used for performing microstep driving, generating pulse current and transmitting the pulse current to the stepping motor. The stepping motor is used for performing rotation according to received pulse current and outputting torque to drive the speed reducing device to rotate. The speed reducing device is used for driving the encoder to be detected to rotate. The encoder to be detected is used for converting self angular displacement in actual rotation into the number of the pulses and feeding back the number of the pulses to the controller. Compared with the prior art, the utilization rate is improved.

Description

technical field [0001] The invention relates to the field of encoder detection, in particular to an incremental encoder detection system. Background technique [0002] An encoder is a device that compiles and converts signals or data into signal forms that can be used for communication, transmission and storage. According to the working principle, encoders can be divided into two types: incremental encoders and absolute encoders. The incremental encoder can convert the displacement into a periodic electrical signal, and then convert the electrical signal into counting pulses, and use the number of pulses to represent the magnitude of the displacement. [0003] The accuracy of the incremental encoder is the basis of the control system. Before the incremental encoder is installed in the control system, it is necessary to test the accuracy of the incremental encoder to avoid the failure of the incremental encoder due to unqualified accuracy. poor performance of the control sys...
