Design of an embedded control and acquisition system for industrial Local Area Networks based on ARM

The design and development of an embedded control and data acquisition system is presented. The system is an intelligent remote unit featuring embedded technology for data acquisition, monitoring and output control. Using a high integrated 32-bit RISC microprocessor as well as serial A/D and D/A converters, the electronic systems are compact and the device has high performance. Besides stand-alone, control, supervision or data acquisition tasks can even be accomplished through Ethernet within an industrial Local Area Network (LAN). Compared with the conventional solutions to control and data acquisition, the device based on the embedded system offers the widest range of features and flexibility, with an overall design for reliability, durability and ease of installation. Expanded input and output capabilities can be added to maximate the system´s functions. Such an embedded system can be used for diverse applications involved in real-time controls and data acquisitions. Because operation systems can be ported to the hardware, the system can deal with much more complicated tasks that conventional lower computers can´t deal with, while the cost is low.
