The document outlines the development of a multi-agent controlled building management system aimed at reducing costs and complexity in current construction management. It emphasizes the creation of a user-friendly interface for control over various subsystems, including lighting, air conditioning, and security. The project has made significant progress in design, simulation, and implementation, with future plans for software and IoT interface development.

➢A Computer-based control system
➢Separate agent for each device
➢Multiple Agents interact with each other
➢Controlling and monitoring electrical devices
❑ What is a multi Agent Building Management System ?
Introduction

3. 3
Motivation
➢ Increasing demand in current construction industry
➢ Existing systems are highly expensive
➢ Complexity of installation

4. 4
Our scope…
To develop a multi agent , wireless building
management system with integrated sub-systems
for Fans , Lighting , Air conditioning, Access
controlling
and security system which can be controlled
through a user friendly interface.

5. 5
Objectives
➢Design plug and play Agents to control each device
wirelessly.
➢Develop an integrated system which Agents
interchange information in between them.
➢Develop a User Friendly Interface to control each
device through Agents.
➢Develop Bidirectional Communication with each
agent and the user interface.

7. 7
Broker
➢ To bidirectional communicate between agent and
user interface
➢ MQTT broker ( Mosquitto )
➢ Subscribe from server to the agent
➢ Publish from agent to the server
