Abstract

The invention belongs to the technical field of data processing, and discloses an encoder position data processing and transmission control system and method and application. The position data processing and transmission control system comprises an absolute position calculation module, an absolute position splicing module, an absolute decoding module, an absolute position difference calculation module, a speed detection module, an absolute position data sending frame number selection module and an RS485 communication module. Through a communication coding optimization mode, the amount of dataneeding to be sent finally is reduced, the data sending time is shortened, and the working real-time performance and the control precision of the servo system are improved; and the problem that an encoder sends a large amount of data is solved, and the problems of insufficient real-time performance, control precision, working performance and the like of a servo system are solved. According to theinvention, the final amount of data needing to be sent by the encoder is effectively reduced, and the data sending time is shortened; and the real-time performance, the precision and the working performance of the whole servo system are improved.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a position data processing and transmission control system, method and application of an encoder. Background technique [0002] At present, the closest existing technology: an encoder is a device that compiles and converts signals (such as bit streams) or data into signal forms that can be used for communication, transmission and storage. The encoder converts angular displacement or linear displacement into an electrical signal, the former is called a code disc, and the latter is called a yardstick. According to the readout method, the encoder can be divided into two types: contact type and non-contact type; according to the working principle, the encoder can be divided into two types: incremental type and absolute type. The incremental encoder converts the displacement into a periodic electrical signal, and then converts the electrical signal into a counting...
