PROBLEM STATEMENT
Mantrac Tanzania Limited the recent available security electric fence does not show or identify the location of intruder when attacking the electrified fencing place. Since the surrounding area is large, the guard took a time to identify the location of intruder when happens.
Also it operates through out the day in 24 hours that is not economical to users hence leading to high operation costs in terms bills to be paid.
An economical Electric fence need to be designed with an intruder locator to locate the intruder location easily.
MAIN OBJECTIVE
To identify location of intruder and to minimize electric power consumption by means of designing of an electric fence with electrical power energy saving capability
SPECIFIC OBJECTIVES
- To design power circuit
- To design sensing Unit for an intruder
- To design a circuit which will detect a intruders and turn on when attack the fence
- To design simulation
- To construct the prototype of the system
- To Testing the prototype
SIGNIFICANCE OF THE PROJECT
- To identify the location of intruder
- To minimize electric bill
- Simplify work to security guarder
Disadvantage of existing system
- Does not show or identify the location of intruder when attacking the electrified fencing place
- High power consumption
Design of Voltage Regulator
The power supply for the most devices associated with the Micro-controller can operate efficiently at 5 Volts. Therefore, the voltage regulator output power recommended is 5 Volts.
LM705 Regulator Features
5V Positive Voltage Regulator
Minimum Input Voltage is 7V
Maximum Input Voltage is 25V
Operating current(IQ) is 5mA
Control unit
Control unit is a part of system that manages all of actions perform by the system.
Program memory should be at least 32Kbytes
Random access memory (RAM) of at least 1 Kbytes
Number of bits for the processor should be at least 8Bits
Processing Speed of at least 16MHz
Low power consumption, Low cost
