| Abstract: | This paper presents a software processing method for grating signal with SCM （Single Chip Microcomputer） as the core component. It describes the system design principle and the design process of software and hardware in details. Two differential signals output from the grating detection circuit are amplified and shaped via the conditioning circuit, AD conversion, properties of direction discrimination and subdivision are attained which is relying on the programming processed by the SCM. This method simplifies system hardware circuit,improves the resolution and strong interference resistance. Experiment result proves to be practical and it can be utilized in machine tool reform and relevant position detection systems. |
