The Research And Design On Real-time Signal Sampling System

Data collection technology requires to be better in modern industrial production and scientific research. It is the most front-end in the factory automation, which determines the whole system implementation precisely, rapidly and completely. As DSP technology continues to improve and prices fell sharply,DSP is more and more widely used.The TCP/IP network controller,which is directly connected to the LAN equipment,has become a trend for building information platform in industrial enterprises.Thus,more and more users want to use computer networks to achieve data collection. In ensuring the accuracy, speed and some data collection functions, users can easily complete a simple-to-multipoint remote data collection.Aimed at a long-range and multi-endpoint data collection, we have built a data collection system using TMS320C6713B and RTL8019AS.This paper has demonstrated the use of Ethernet for data collection and transmission reliability and feasibility. This paper describes the details of the hardware and software development, and describes the experimental results in detail.
