Paper Abstract

Rotary position sensors are widely used in many applications that require precise shaft unlimited rotation: including control systems, robotics and AR (Augmented Reality) systems. However, traditional data acquisition system is often a PC-based (Personal Computer-based) one with complex structures and complicated electrical connections, which means that the system has limited application for its size as well as its poor portability. That is a main drawback, especially for AR system in which the user is supposed to walk freely. In this paper, a novel portable data acquisition system (PDAS) based on USB interface technology with a succinct hardware structure is proposed. Implemented on an 8051-based microcontroller AT89C5131, the proposed system can receive signal from optical encoder, decode the signal and transfer the data to the computer through USB interface. The experimental results show that this system can provide the possibility to realize portable and improve performance of AR, which demonstrate the efficiency of the proposed system.
