Heating Management System Based on Wireless Sensor Networks

An innovative approach to managing of building heating systems based on wireless sensor networks is proposed. Main feature of the management problem is that the number of temperature conditions for each network sensor significantly outnumbers heat supply controllers and actuating devices. The management problem is formulated for big measurement data with limited number of control actions. From mathematical point of view the problem may be defined as inconsistent inequalities solution. An algorithm based on branch and bounds method is proposed for solving the problem in real time. The algorithm allows determining global maximum of attained temperature conditions. A distributed heat supply management system based on wireless sensor networks for university campus of the South Ural State University is considered. The campus contains 35 administrative buildings and dormitories, water pool, sports complex with energy supply by different sources including CHP. It is demonstrated that sensor network application allows minimizing heat supply consumption with 16,5% energy efficiency gain.
