INTRODUCTION
• Every years GIM Department gives to its students a challenge to developt a simple project.
• There is an Energy platform in GIM Department which is developed continuesly by their students every year.
• Last year, some students of Licence PRIME along with some students of EILCO installed an arduino in the platform in order to acquire temperatures data which were stored in a cloud server.

PROBLEMS
• The electrical production and distribution systems need to be monitored which can be done by SCADA
• Actualy there has already exists a sensing device in this system, brought by the solar controller, but we don’t have the software for acquiring the data
•Arduino for a low cost solution

Introduction
VIRTUAL SERVER + MY SQL
Because the server in IUT use a virtual machine, so we also use a virtual machine with Debian « Crunchbang » Operating Systems for our server database.
MySQL Preparation:
• Create a user
• Create a database
• Create a table

ARDUINO CONFIGURATION
• Arduino Configuration:
• Ethernet Shield + Module PoE
• RS232 Shield
• Use Software Serial library in order to make two serial communications between RS232 – Arduino – Ethernet.

Introduction
SERIAL COMMUNICATION
• RS232 Protocol :
• Baudrate: 1200; Parity: no; Databits: 8; Stopbits: 1
• To retrieve the data the PC must send F<CRLF>
• Response of the SCD: In this sequence the data will be returned as ASCII signs.
• R: current voltage; current power; current temperature; minimum voltage; maximum voltage; minimum power; maximum power; CRLF
• R:12,85;13,0; 9;11,60;21,94; 8,9;15,8;

FUTURE DEVELOPMENT
• Resolving the problem due to data transfer failure or problem with more viable code.
• Supervising datas in the server database (In progress with EILCO Students)
• Install several relay as a control switch, which is connected with arduino to manage batteries charging and usage
• Using SCADA with weather information to perform a study of photovoltaic panels and wind turbine performance, later can be use to plan a maintenance.
