摘      要：Two laboratory-scale experiments have been developed that can be executed safely over the Internet. They provide practical experience for students of process control. Remote access is within a client-server paradigm. Servers connected to the processes through the usual data acquisition hardware address issues regarding safety, security, data validation, and session management. A unique feature of the lab is the ability for the student to design, test, and verify control strategies in real time over the Internet. Necessary interlocks and cutoffs ensure safe remote operation of the units. Studies have shown that network speeds are not a significant concern for these systems due to slow process dynamics. The availability of Internet-mediated laboratory modules on an anytime/anywhere basis will enable a larger fraction of the class to get valuable laboratory experience. These experiments have also been used in an Internet-wired classroom for interactive demonstrations during lecture.
