1.1 Power Line VanadalismDetector System
A power line
vandalismdetector system is a high-voltage transmission line anti
tampering electronic security device specially designed to remotely
monitor and protect the lineagainst vandals. The system detects when
the transmission line is vandalized and as well when the vandals entered
in the vicinity where there the transmission line tower is installed.
This means that the system can sense unauthorized movement of objects
(caused by humans or nature) around the transmission lines. The system
circuitry consists of sensor nodes, buffer, alarm circuit, a power
supply unit and a controller which processes data and triggers an alarm.
The alarm sound comes from an output transducer called buzzer. The
system at the same time communicates wirelessly to the power line
operators and the law enforcement using radio frequency (RF) signal
network.
1.2 Design Considerations
The first design
consideration of the project is the availability of the components to
actualize a power line vandalism monitoring system. The available
electronic components in the country, with considerations based on sound
economic overview for its availability and affordability. In the design
the following below are also considered for the effectiveness and
further development of the system.
1.3 High frequency alarm system:
A
high frequency alarm sound is used to alert the people at the power
station when the vandalism is about to take place. This assist the
police, military and Para-military in their duty to ensure adequate
monitoring and protection of power lines. The law enforcement bodies
cannot be everywhere at every time, so when this alarm sounds at the
power station, then they can alert the security agency close to the
targeted destination. This is why in this project design included a high
frequency alarm which can give an attractive high frequency sound that
can alert anyone around when the vandals intruded to the power line
vicinity.
