Abstract

The absolute grating ruler information interaction system and method belong to the field of absolute grating ruler measurement. In order to solve the problem of poor information interaction existing in the existing grating ruler acquisition system, the communication protocol conversion interface and the absolute grating ruler transmit data to each other and send information to the information acquisition module. Output information, input configuration information; information reading information of the absolute grating scale is transmitted to the information analysis module; the information configuration module receives the configuration information of the information analysis module, and then transmits the configuration information to the absolute grating scale; the information analysis module reads the information The fetching module makes a request to access the absolute grating scale, the information reading module reads the information of the absolute grating scale, and transmits the information to the information analysis module, the information analysis module analyzes the data, and transmits configuration parameters to the configuration information configuration module, parameter configuration The module transmits configuration parameters to the absolute grating ruler; the analog signal conversion module receives the analog incremental signal of the absolute grating ruler and outputs it to the 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...
