A Building Management System is a Computer based system which can monitor and control different mechanical and electrical equipment in a building. A reliable, efficient and integrated controlling among these equipment’s in a building is the main objective of a Building Management System. This paper presents a Multi Agent Controlled Building Management System which is controlled as an agent based integrated system of different subsystems such as Lighting, Security, Air-conditioning, Ventilation (PDF) Multi-agent controlled building management system.

➢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.

6. System Architecture

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
