Occupancy Monitoring

Location of appropriate seats in seating areas of theaters remains a significant challenge that patrons of these enterprises face. There is therefore, the need for seat occupancy monitoring system to provide readily accessible seat occupancy information to clients and management of these halls. This paper presents the design and implementation of a low cost seat occupancy detection and display system which is capable of monitoring seat occupancy in halls efficiently.  The system uses capacitive seat sensors which is designed based on the loading mode technology. It detects the presence of a human occupant using a single electrode. Occupancy data is relayed to a WiFi-enabled microcontroller unit which processes the data and wirelessly transfers the processed data to a central base station over a local area network for graphical and numerical display. Commands are also transferred from the base station to the microcontroller units when needed. Theoretical and empirical results show that the system is able to achieve seat occupancy monitoring accurately, neatly and cost effectively.Keywords: Capacitive sensing, seat occupancy, sensor cluster, microstrip transmission line, Wi-Fi

This paper presents the design of energy supply and management system to achieve minimum cost of charging the electric vehicles and to reduce the peak power drawn by all electric loads in a microgrid. We consider energy management function at different levels of microgrid like, at stand-alone EV parking lot, at residential loads and at commercial building loads, etc. The energy supply and management system is not only connected to the power grid but also with a combination of fixed Worldwide Interoperability for Microwave Access (WiMAX) and Local Area Network (LAN). First we perform load balancing among different kinds of loads in a microgrid such that extra electrical resource may be transferred to resource constrained loads by using game theoretic approach, and later we propose a distributed algorithm for load scheduling of electric vehicles parked in stand-alone parking lot in microgrid to minimize the sum of total energy cost for charging the battery of electric vehicles and spreading out the charging power equally over the charging time using interior point method (IPM). This results in reduction of peak charging power based on EVs own consumption schedule while they select the best response in energy consumption game.
