A raster precision low-speed detecting encoder means

A raster precision low-speed detecting encoder apparatus comprising a housing, an encoder signal tessellation module, the data processing circuit DSP module configured interactive data communication interface. Device external crystal oscillator as the clock source, the DSP as a data acquisition and processing unit, the peripheral circuit includes an encoder signal division circuit, serial communication circuit and a display module. Grating encoder signals by reading means mounted on the rotary shaft, the timing or angle measurement mode measurement given angular rate measurement accuracy. This test uses an embedded DSP device as the data processing unit, compared with the traditional use of PCI data acquisition card implementation rate detected by IPC software, greatly reduce the volume of the device; means for using segments circuit module, the user can adjust the actual signal interpolation factors, improve the detection accuracy; the DSP strong data processing capabilities, to ensure the efficient and stable test device.
