The invention discloses a portable encoder detection device based on an FPGA. The device comprises a case, an FPGA data collection board, a display screen, a power switch, and a switching power supply, wherein the FPGA data collection board, the display screen, the power switch, and the switching power supply are disposed in the case; and the data collection board is connected with an encoder andthe display screen, and the switching power supply is connected with the data collection board through the power switch. An encoder angle value and a pulse number are acquired by using the FPGA data collection board, and a corresponding rotating speed is calculated; and the angle value, the pulse number and a rotating speed curve of the encoder are displayed through the display screen, the rotating speed is compared with the rotating speed in normal operation, if the rotating speed curve is smooth and free of jumping, the encoder is indicated to work normally, a slip ring and a variable pitchfan system work normally, and if not, the encoder is indicated to work abnormally. The device is convenient to carry, easy to operate, visual in display and low in cost.

Portable encoder detection device and method based on FPGA

The invention relates to an encoder output waveform tester, and belongs to the field of a detection instrument. The tester comprises a product clamp assembly, a motor assembly and a data acquisition system. The product clamp assembly comprises a product fixation device and wiring terminals. The product fixation device is used for fixing a product to be tested, wherein the product to be tested has a roller wheel; and the wiring terminals are used for connecting the product to be tested and the data acquisition system. The motor assembly comprises a rotating disk and a motor. The rotating disk makes contact with the roller wheel of the product to be tested; the motor provides power for the rotating disk to realize uniform rotation; and the rotating disk can drive the roller wheel to rotate. The data acquisition system can collect pulse signals generated by the product to be tested in real time, and carry out data processing on the collected signals and result display. The detection method is reliable; the detection result is visual; and the encoder output waveform tester is simple in structure, low in production cost, stable and reliable in data acquisition, high in detection accuracy, high in popularization performance, and especially suitable for popularization and application of small and micro enterprises.
