Implementation of wireless intelligent street lighting with phase-detection system

Abstract

The advancement of technologies in wireless communication has led to several engineering designs for human requirements to solve a country’s problems. Ghana as a country has issues with power instability on domestic, single-phase lines, to monitor some of these line faults “example when an area power outage occurs is a problem for the power distribution company to be aware of this fault ”, this intelligent wireless street lighting with a phase-detection system is to solve this problem by automatically switch power sources to the battery which powers the streetlight when the national gridline is off, for temporal light at the location or area and also send a monitoring notification to the fault monitoring office, with the fault code for feather investigation. The project consists of a battery, inverter circuit, microcontroller, LCD, and current sensor. The system power battery stores a current of 9Ah (Ampere-hour), which means the battery can provide 9 amperes of current in one hour which can sustain three light units to the next morning. Since the system uses a 3.3 ampere the lamp, the battery can produce power within 6 hours before the power supply will be switched to the power grid for charging or for the fault to be rectified. From the data gathered, we can say that it is possible to use a streetlight to monitor line faults and also produce a two-way powering street light. The system is proven to be effective and operational.
