Integration of networked embedded systems into power equipment remote control and monitoring

Two networked embedded systems for existent power equipment are designed in this paper to achieve the goal of remote control and monitoring. Since the basic requirement of industrial control and monitoring systems is the response time; therefore, time constraint is the first consideration in designing networked embedded systems. Telnet and Web server are the commonly used Internet functions for embedded systems. The embedded Web server based system is definitely the better choice for power equipment control and monitoring. However, due to the response time constraint, memory capacity and processing power of embedded systems, a Telnet based system is also presented in this paper. Since RS232 is the most popular communication media for existent power equipment; the developed embedded system is deigned to communicate with the existent power equipment by RS232. After the data retrieved from the power equipment, the designed system can transmit those data to remote control center via the Internet. The experimental platform shown in this paper is a Samsung S3C4510-based embedded system. The embedded system features uCLinux operating system; therefore, the design and implementation of these proposed networked systems could be more effective. Experimental results show that the designed networked embedded systems can be integrated into power equipment effectively.
