Robot high speed measurement and control system based on LVDS looped network bus and robot high speed measurement and control method thereof

Abstract

The invention discloses a robot high speed measurement and control system based on an LVDS looped network bus and a robot high speed measurement and control method thereof. The system comprises a master control computer, a data communication main module and multiple data acquisition modules. The multiple data acquisition modules are connected in turn, and a looped network is formed by the multiple data acquisition modules and the data communication main module. The master control computer generates control signals, and the control signals are transmitted to all nodes of the looped network by the data communication main module. The data acquired by sensors are aggregated to the data communication main module to be processed through all nodes of the looped link and the processing result is transmitted back to the master control computer. The anti-noise and anti-interference capability can be enhanced, and the problem of signal clock irregularity of limiting the data transmission rate can be solved by the clock and data recovery technology so that the data rate of data transmission can be enhanced; and the system has excellent performance of high multi-load utilization rate, insensitivity of the network performance to distance and fair accessing.

Description

technical field [0001] The invention relates to the technical field of digital communication network measurement and control, in particular to a robot high-speed measurement and control system and method based on an LVDS ring network bus. Background technique [0002] In the field of digital communication in robotics, a large amount of data needs to be transmitted between systems. Because the bus is a very important part of the system, it acts as a bridge for communication between systems, plays a vital role in improving system performance, and provides an effective guarantee for data transmission between systems. The bus technology has become the key technology to build a large-scale test system. However, with the increase of the number of sensors of the robot, the continuous increase of the amount of data to be transmitted, and the dispersion of the layout of the data acquisition module, the continuous increase of the clock speed, the offset between the clock and the sign...
