Zigbee Technology

Zigbee technology is a kind of bi-directional wireless communication technology characterized by close distance, low complexity, low power consumption, low speed and low cost. It is mainly used for data transmission of various electronic equipments with short distance, low power consumption and low transmission speed, as well as application of typical periodic data, intermittent data and low reaction time data transmission. This thesis first of all makes an analysis of characteristics of zigbee technology, based on which the design of wireless intelligent home control system based on zigbee technology is proposed. Finally, it gives an analysis of the daily management and maintenance of intelligent system, so as to contribute to further studies.

Abstract Water management system towards the country is the biggest challenge to distribute the water to each corner of the country and keeps track of all the information to store it centrally which helps the government in analyzing and predicting the water situation of the country. For implementing the above things the crucial barriers are electrification and network spread all over the country which is a difficult task. The main purpose of this suggested work is to design a wide area network using low power consumption called the LoRa network. Using this network the resultant value of the water meter can transmit to the cloud to make a secure centralized repository system which helps the government as well as different business organizations a lot. The proposed work explains the whole architecture of the end-to-end communication system from water meter to cloud as well as defines all the components for managing end-user and applications. Due to low power consumption the whole communication system, and water meter, can be powered through solar energy through which electrification supply is not required. Hence using the explained technique we can efficiently monitor and collect information from every corner of a country efficiently to manage the consumption of drinking water which helps society a lot.

This paper presents a low power consumption and low cost automatic data collection network for water meter application. Based on transmission performance and power consumption, several low cost sub-GHz wireless transceivers are analyzed and compared, and consequently a suitable hardware is chosen. The associated network protocol stack is also examined. To construct the automatic collecting data mechanism, we consider a cluster based wireless sensor network (WSN) where routers and a GPRS gateway are used to link each cluster to a data collection center. Advantages of this proposed configuration are the simple implementation, low cost and low power consumption. By using the Monte Carlo simulation technique, packet delivery ratio and power consumption for different topologies are investigated. Based on obtained results, the optimum network topology for automatic water meter reading in a typical urban environment is finally proposed.

Shim Coil

It is necessary to develop a high homogeneous, low power consumption, high frequency and small-size shim coil for high precision and low-cost atomic spin gyroscope (ASG). To provide the shim coil, a multi-objective optimization design method is proposed. All structural parameters including the wire diameter are optimized. In addition to the homogeneity, the size of optimized coil, especially the axial position and winding number, is restricted to develop the small-size shim coil with low power consumption. The 0-1 linear programming is adopted in the optimal model to conveniently describe winding distributions. The branch and bound algorithm is used to solve this model. Theoretical optimization results show that the homogeneity of the optimized shim coil is several orders of magnitudes better than the same-size solenoid. A simulation experiment is also conducted. Experimental results show that optimization results are verified, and power consumption of the optimized coil is about half of the solenoid when providing the same uniform magnetic field. This indicates that the proposed optimal method is feasible to develop shim coil for ASG.
