Arabic Abstract
الماء هو المورد الطبيعي الأكثر قيمة بعد الهواء. الطلب المتزايد على المياه اكثر بكثير مما هو متوفر. يمكن الاستفادة من التقدم في التكنولوجيا والاستفادة من الأنظمة الذكية في إدارة استهلاك المياه في جهة المستهلك. ويتم ذلك من خلال التأكد من أن امدادات المياه تتناسب مع الطلب ومن أن المياه تُضخ بمعدل تدفق ثابت ومريح. بالإمكان تحقيق هذه الأهداف من خلال استخدة تقنيات الإستشعار والإتصالات اللاسلكية الحديثة. يعمل النظام المُقترح على أساس تجميع البيانات من جهة المستخدم ومعالجتها ومن ثم أخذ قرارات مناسبة للتحكم في مكائن ضخ المياه مما يزيد في عمرها ويقلل من استهلاك الطاقة. لاحظنا في تجارب المحاكاة التي قمنا بها بأننا نستطيع توفير ما يقرب من ٥٠ - ٦٠ ٪ من المياه و ٦٥ - ٧٥٪ من الطاقة
English Abstract
Water is the most valuable natural resource after air. The growing demand is forcing fresh water supplies beyond their natural replenishment rates. Leveraging the advancements in technology and utilizing of smart systems can do significant savings by managing water consumption in the demand side. One of such venues is to match the supply of water to the demands that vary over time. This is achieved by varying the supply of water according to the number of active users on the network. In this thesis, we propose a novel water pumping system that employs wireless and sensor technologies. The proposed combination of wireless and sensing technologies with mechanical systems is energy efficient as well as it saves water by serving it to the users at a consistent and comfortable flow rate. The new system is appropriate for residential, commercial and public buildings. It replaces, the customary single pump by a set of pumps having a binary sequence (1, 2, 4, 8 …) of pumping capacity. This approach facilitates having several levels of output that accommodates variable demands. Additionally, the concept of variable speed pumps for adaptive water pumping based upon user requirements in smart homes is introduced in this thesis. In order to meet the above objectives, simulation models of the newly proposed systems are developed using Matlab. These models are used to assess the operation of the systems as well as the quality of their services. Various simulations replicating real life scenarios are done. The obtained results are analyzed and compared with those obtained by simulating conventional systems such as the single pump and a set of identical pumps. The results show that the proposed systems not only provides significant water and energy savings but also offers an enhanced quality of service to the users. For example, in realistic scenarios of 2.5 and 4.5 average active users in the system, we have observed savings of 50-60% in water and 65-75% in energy.
