In this paper, an effective low-cost heating, ventilation, and air conditioning (HVAC) control system incorporating a new sensor is proposed. This research builds upon our previous system, which achieved efficient control of the air conditioning (AC) for a large room in a library. By detecting whether or not individual chairs were occupied and regulating the AC near unoccupied chairs, the system reduced...
This paper presents design, implementation and testing of Theft and maintenance monitoring of batteries of Stand-alone SPV Systems. Solar Photovoltaic stand alone power sources are popularly used for outdoor lighting, viz, garden lighting, street lighting etc. Batteries are invariably used to store the solar energy during its availability. Solar power energy sources and the batteries are often located...
An AUV is designed to perform water pollution infestation task in Songhua Lake, the biggest lake in the north of china, due to severe pollution accidents occurred in recent years. In order to extend duration to 10-15 hours, three groups VRLA batteries are employed, ensures the routine patrol line to 26Km. This paper described the AUV power arrangement optimization: internal resistance, temperature...
Wireless sensor network is need of present era or advanced technology. In this paper we have presented the details of methodology followed for implementation of a wireless sensor network in a process plant for based solution for data acquisition in a process plant. Due to its specific approach the solution not only acquires the data but also serves very effectively as a maintenance and diagnostic...
Back-up batteries are intended to meet the immediate requirements of the plant during emergencies or failures in the control supplies. Battery maintenance plays a very important role in running the plant continuously. There are approximately 1000 battery charges and uninterruptable power supplies (UPSs) in petroleum development Oman (PDO), each battery charger is attached to, on average, 84 cells...
