Abstract

The invention relates to an information interaction system and method of an absolute type grating ruler, belongs to the measurement field of the absolute type grating ruler,, and aims at solving the problem that a present grating ruler collection system is low in information interactivity. A communication protocol conversion interface and the absolute type grating ruler transmit data to each other, the communication protocol conversion interface outputs information to an information collection module, and configuration information is input to the communication protocol conversion interface; an information reading module transmits information of the absolute type grating ruler to an information analysis module; an information configuration module receives configuration information of the information analysis module, and transmits the configuration information to the absolute type grating ruler; an information analysis module makes a request for accessing the absolute grating ruler to the information reading module, the information reading module reads information of the absolute type grating ruler, and transmits the information to the information analysis module, the information analysis module analyzes the data and configures the transmission configuration parameter of the information configuration module, and the parameter configuration module transmits configuration parameters to the absolute type grating ruler; and an analog signal conversion module receives analog increment signals of the absolute grating ruler, and outputs the analog increment signals to an oscilloscope.

Description

technical field [0001] The invention relates to an absolute grating ruler information interaction system and method, and belongs to the field of absolute grating ruler measurement. Background technique [0002] Absolute grating scales are mainly used in high-end numerical control systems as full-closed loops. Its advantages are: the absolute position information can be obtained when the system is powered on, and there is no need to find the zero position. It is optical detection, non-contact and not easy to wear. The absolute grating scale is an essential key component of the future CNC industry, therefore, it is very necessary to propose a system that can exchange information with the absolute grating scale. [0003] At present, the domestic and absolute grating rulers have poor information interaction, low flexibility, and insufficient intelligence, resulting in low production efficiency and narrow application range. Therefore, it is very necessary to design an information...
