Software Method for the Signal Processing of Grating Based on SCM

Abstract:

For the purpose of improving the interference resistance and accuracy of the grating detection system, a SCM-based software design method for grating signal processing is proposed in the thesis. In the method, two differential signals output from the grating detection circuit are amplified and shaped via the conditioning circuit, converted into digital quantity through AD conversion and processed by the SCM. Relying on the programming, properties of direction discrimination and subdivision are attained while effective computation accuracy of subdivided data and signal processing speed are guaranteed. The software processing method simplifies system hardware circuit, cuts down the cost, improves the resolution and measurement precision of the system due to the stable performance and strong interference resistance. The method is experimentally proved to be practical and worthy of promotion, which can be utilized in machine tool reform and relevant position detection systems.
