Which was the initial framework for our laboratory? post Client http Protocol WEB Server http Protocol post SQL Server xml Laboratory. Server LAN with Measurement Devices, Sources, UUT xml Laboratory. Server Domo. Control 128 &Tiny. Domo. T

Which are the goals of our work? • To implement a work shop in the field of Home Appliance domain (Domotics) • To realize a coherent (unified) image about the processes controlled in the house • To offer a dynamically adapted system for home appliances • To add remote control capabilities for our system • To assure a versatile, and anywhere/anytime available to be use in the e-learning process (and not only)

Two implementations for the remote accessed elements Usage of two already available experiments are considered both experiments are targeted for remote monitoring of an automated house: • Domo. Control 128 based (UTBrasov+PSE drive – “industrial prototype”) • Tiny. Domot based (UNINOVA drive – “academic prototype”) What we intend to accomplish in the near future: • Common protocol for both solutions

Tiny. Domot Networked controllers Communication among controllers: - dedicated line (RS-485) - LAN (ethernet) - power-line - wireless

Tiny. Domot Networked controllers Each Tiny. Domot is based on one PIC microcontroller (16 F 87 x) Every Tiny. Domot has several digital inputs and outputs Possible to define automatic events and relations between inputs and outputs of different Tiny. Domots Two types of Tiny. Domots are foreseen: - to interact with users - to be embedded in a equipment or an appliance For Tiny. Domot for user interaction: - availability of additional LCD and telephone keypad

Structure of DOMOCONTROL 128 system

DOMOCONTROL 128: main features Acquisition of analog input signals 12 channels (10 bits resolution - 500 ms sampling period ) Acquisition of digital input signals 16 channels Command for two analog output signal (12 bits resolution) Command of sixteen digital output channels Temporization 8 independent channels (including the real time clock ) Watch dog function Brown detection level Four serial USART units (two RS 485, one RS 232, one TTL level) SPI channel communication EEPROM memory & SRAM memory 4 MBits/32 KBytes

Adaptation as energy counter IEC 62056 DLMS Standard

Consequences in terms of interoperability Ø Single set operation of lighting, or in general to control digital actuators Ø Logical interaction between intelligent systems Ø Will accept multiple manufacturers systems (interoperability) Ø Interaction with energy management systems Ø Interaction with client enterprises such as accounting systems

Advantages of this system • • Scalability Easy reconfiguration Design focused on functions Double role: node of network -(router)-, / local server and universal module for control • Uniform mode for programming & work signal level(e. g. for analogue signals we define 8 different level view like digital values that could be integrate in formulas) • Easy to configuration the system using different ways: serial programming, ISP, local keyboard, Ir. DA devices

Didactical considerations • We consider three types of users with different levels of permissions: • Introductory ØMonitor and control the variables • Intermediate ØCan configure the system • Advance ØCan reconfigure and reprogramming of the associated controller

Conclusions • The paper presents a remote laboratory targeted for remote monitoring and control of home appliances. • Two dedicated systems were developed (named as Domo. Control 128 and Tiny. Domots). • Full interconnection between the two systems is foreseen for the near future. • Exploitation of remote monitoring and remote reprogramming capabilities of the system can allow students to test different control strategies applied to specific sub-systems within the house or the building.
