New Architecture of Remote Laboratories Multiuser based on Embedded Web Server

Abstract—This paper presents a new architecture for multiuser remote laboratory based on an embedded web server used for experiment with the MCS-51 microcontroller system. The design for the remote lab uses a green computing approach, with the aim of reducing energy consumption, lowering the cost of procurement systems, improving performance and use, and also saving space. The remote lab system uses multi user and multi device architecture to support collaborative work and improve scalability. The design of the remote lab has n modules experiment, and each module can be accessed by a single user or a group which consists of several user. The prototype of a remote lab that has been realized consists of an embedded web server based on Raspberry Pi as the remote lab gateway and 2 experiment modules that are controlled by an embedded web server based on MCS-51 microcontroller. Development of the system is expected to contribute to creating an efficient remote lab that is able to facilitate collaborative work and support green computing.
