Remote laboratories multiuser based on embedded web server

Abstract

This paper presents a new design of remote laboratory multiuser based embedded web server that is used for the lab microcontroller system. Architecture of Remote Lab System consists of a computer server, two experiment module microcontroller system and two embedded web server for controlling lab modules. The computer server is used as a web server remote lab that serves as a homepage and user management. Embedded web server serves as the user interface to control the lab module microcontroller via the internet. The novelty of the system proposed is the remote laboratory architecture is multi user, and embedded web server designed more intelligently that function as lab modul controller, such as ability to send log event data to database server and ability to send message to chat applications. This research activity has resulted a remote laboratory based on embedded web server, the system is multiuser so that at the same time can be used by more than one user. Test result, the system can work quite well. Index Terms-Remote Laboratories, Embedded Web Server, MicrocontrollerI.

Pengujian Kinerja Web Server Polinema Menggunakan Alat Uji Jmeter

“…WWW terdiri dari seluruh situs web yang tersedia kepada publik. Halamanhalaman sebuah situs web (web page) diakses dari sebuah URL yang menjadi "akar" ( root ), yang disebut homepage (halaman induk; sering diterjemahkan menjadi "beranda", "halaman muka"), URL ini mengatur web page untuk menjadi sebuah hirarki, meskipun hyperlink-hyperlink yang ada di halaman tersebut mengatur para pembaca dan memberitahu mereka susunan keseluruhan dan bagaimana arus informasi ini berjalan [9]- [10].…”

LABENVI, un dispositif pour les travaux pratiques à distance : Présentation et analyse des nouveaux usages

“…Comment utiliser efficacement, d'un point de vue pédagogique, des ressources accessibles à un seul utilisateur et à plusieurs utilisateurs à la fois ? De nombreuses études ont déjà été publiées dans ce domaine (Cooper et Ferreira, 2009 ;Limpraptono et al, 2012 ;Markan et al, 2012), mais nous souhaitons apporter ici un retour d'expérience, après quatre années de mise en oeuvre de TP à distance, conduisant à s'interroger selon une approche non plus technocentrique mais plutôt anthropocentrique des TIC. Il en résulte quelques perspectives sur l'évolution des métiers d'enseignant, de tuteur ou encore de technicien de laboratoire.…”

Remote Laboratory Offered as Hardware-as-a-Service Infrastructure

“…Another branch of education deserves particular attention, which aims to deliver a remote environment concerning wide range of microcontrollers [9], programmable devices, such as FPGAs [10], and data collection and monitoring equipment [11,12]. Over the years, a variety of solutions has emerged which usually delivers a web-based system with user interface that facilitates interaction with hardware, and in particular with microcontrollers [13][14][15]. Some of the remote laboratories are not exclusively dedicated to microcontrollers, but offer help in the investigation of physical phenomenons [16] or give the ability to control a robotic arm [17].…”
