farmer friendly solar based electric fence system for rural agriculture with circuit diagram

Electric fences can be used to protect farmhouses, farmlands, forest bunglows, etc from animals. In a way, these simulate the job of a cowboy or forest guard. Already popular in countries where manpower is expensive, electric fences are slowly becoming popular in India as well. These control the animals by giving them a short, sharp but safe shock that teaches them to stay away from the fence. Thus electric fences are economical and practical solutions to maximize field production through controlled grazing. Electric fencing is safe, as its output is discrete (not continuous). There is certain time duration between two pulses that prevents prolonged shocking to animals or people. In addition, the short ‘on’-time (normally 1/5000th of a second) prevents heat build-up. This fence system is powered by a 12V rechargeable battery. A solar panel is connected to the battery to charge on day time. The battery is connected to the inverter. This inverter is used to convert the 12 Volt D.C to the 230 Volt A.C. This 230 Volt A.C voltage is used to activate the loads. Here we are also using Conventional Battery Charger Unit to recharge the battery. AT89S52 micro controller is the heart of the circuit as it controls all the functions. A voltage sampler is interfaced with the system using ADC 0808 to get the DC voltage generated from solar panel stored in battery as a display on a 16X2 LCD. A 12 V DC lead acid rechargeable battery is used for storing the energy. We are using conventional battery charging unit also for giving supply to the circuitry. This Conventional power source uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer.
