On-Line Remote Data Acquisition and Control System for Embedded Real Time Applications

A typical Data Acquisition System (DAS) consists of individual sensors with the necessary signal conditioning, data conversion, data processing, multiplexing, data handling and associated transmission, storage and display data. This paper describes the DAS that is very useful in keeping track of data from sensors recording values from the environment in real time. The data collected from the sensor may be transmitted over long distances from the test center to the controlling authority. Analog data is acquired and converted into digital form for the purpose of processing, transmission, display and storage. A data can be transmitted transparently through Ethernet interface unit to the remote end desktop computer. While becoming the dominant LAN technology, Ethernet has proven to be a very effective and very economical PC networking solution. With 10 Mbps and 100 Mbps Ethernet components widely available at a relatively low cost, This design has the advantage of cost-effective, easily realized, stable and reliable transmission and so
