Microcomputer based embedded SCADA and RFID systems implemented on LINUX platform

Possibilities and ways of design, implementation and application of microcomputer based embedded SCADA and RFID systems implemented on LINUX platform are considered, proposed and described in the paper. It is proposed to use open source hardware and software microcomputer technologies for design and implementation of the systems. Major possibilities and advantages of implementation and application of such systems are described. One such practically designed and implemented system that performs data acquisition and appropriate control is presented and described. Technologies used to realize the system, as well as embedded application of such solution are described. The system hardware was implemented using open source microcomputer boards, RFID and other sensors, WiFi router and additional electronics. The system software was implemented using open source tools and programs and LINUX operating system. The system was realized using modular approach. It enables easy system expandability, simplifying maintenance and adapting of the system to user requirements and needs. Access to system monitoring and control is possible using web based user interface and command line interface. It is achieved balance between functionality and cost of the system. Main advantages of the system compared with standard SCADA and RFID systems are low cost of the system, optimization according to user requirements and needs and low consumption of electrical energy. It is specialized and optimized system for specific requirements and needs.
