Design And Manufacture

An inverter is a circuit which converts the AC voltage into DC voltage. Current use of inverters is very large, especially in industries, offices and housing. Even though now there are many inverter markets, but many are used for household loads, no one uses an inverter for roads lighting system namely sodium lamp because it requires a high frequency and voltage Then the surveyors placed a single phase inverter from the sodium lamp. Single phase inverter tool designed produces a voltage of 10,000 V, Amperage current of 0.20 A and 2000 w Power when tested against overloaded and not overloaded inverter, the results are quite good but in the design and manufacture of a single phase inverter is still lacking, which is only able to start the initial lighting of the sodium lamp because the current is small and the resulting voltage is unstable. Keywords: Single phase inverter, electrical energy, public road lighting, sodium lamp.

This document addresses the development of a novel methodology to identify the actual maintenance factor of the luminaires of an outdoor lighting installation in order to assess their lighting performance. The method is based on the combined use of Radiance, a free and open-source tool, for the modeling and simulation of lighting scenes, and GenOpt, a generic optimization program, for the calibration of the model. The application of this methodology allows the quantification of the deterioration of the road lighting system and the identification of luminaires that show irregularities in their operation. Values lower than 9% for the error confirm that this research can contribute to the management of street lighting by assessing real road conditions.

After discussing the charging and discharging characteristics of valve regulated lead acid(VRLA) battery, we described the working principle of UC3906. Then designed the controller of 12V battery charge circuit, 12V battery discharge protection circuit and lamp detection control circuit. This controller achieved automatic switch of lighting system, it could efficiently charge the battery and avoid over-charge or over-discharge. The result showed that this controller extend the life of the battery.

In this study, firstly, we compare various kinds of imitator robots and then by investigating of various fish robots properties, we design a mechanism and control circuit for a kind of these robots which its structure was inspired from knife fish. This robot has a segmental anal fin in its bottom which produces required force for advancement and maneuver. It consists of two servomotors and uses a kind of mechanical system to change direction and depth which is presented in this work. Another property of this robot is the existence of density control box for robot suspension which increases its capability for freight. The required signals are sent to this robot to produce the movement and maneuver by using a control handle and a wireless system which are installed on a control board. Therefore, it is possible to control the robot from out of the pool. In this paper, an electrical circuit is designed to control servomotors which enables us to control revolution, speed and phase differences of neighbor servomotors in fins. We also control two servomotors to regulate direction and depth.

In this study, design and implementation of a new cost-efficient daylight-based lighting control system is proposed to provide energy saving in a public building with a conventional lighting system. Energy gain recovery and regional daylight utilization coefficients are obtained by conducting daylight measurements in all indoor spaces of the building where the proposed lighting system will be applied. Daylight value is continuously transferred to the control system through the pyranometer placed outside and the need for artificial lighting is calculated by using sectional daylight utilization coefficients. Thereby, maximum benefit from daylight is realized when unnecessary energy consumption for artificial lighting is reduced. Experimental measurement results show that the proposed daylight-based lighting control system provides an average energy efficiency of the building at the level of 60 %. Additionally, the required investment, such as operating cost and payback period for converting an existing conventional lighting system into the proposed system, are discussed in detail. Cost analysis shows that the payback period of the proposed system can be reduced by 5 years compared to the conventional system.
