碩士 === 國立高雄應用科技大學 === 電機工程系博碩士班 === 102 === Currently, the street light system were managed by Taiwan Power Company that includes power supply, vanishing point control, repairing and maintenance. The street light system adopted parallel power supply and serial control in Taiwan, but the maintenance relys on manual handling work. Recently, Taiwan Power Company reflects that the street light switches always breakdown in Low Voltage System, and lead to the workers repairing frequently. The purpose of this study is to analyze the damage reason for the street light switches that Taiwan Power Company used. The first step is to collect the damaged cases of street light switches and discuss the design of the street light switches circuit and component specification. Besides, Using Equipment to make an experiment on surge test, temperature, and humidity for analyzing the street light switches in different environment. Finally, to select the monitoring place by the information, and building the real-time street light switch monitoring system. Though the GPRS Wireless communication technology, the information which includes voltage, current, temperature, and humidity will send back to data server, and display on the website. In the future, user can take the historical information to diagnosis by exporting the run chart to analyze the voltage, current, temperature and humidity.
