Implementación de un prototipo de un cerco eléctrico para protección de ganado utilizando energía solar y envío de mensajes cuando exista una violación del sistema.

Abstract

This work deals with the design and implementation of a self-sustaining electric fence prototype with a warning system if there is a perimeter violation for protection or the grazing of livestock. It was conducted to provide a technological tool for small and mid-sized cattle farmers. It was drawn form of the electronic and electric design where a 12 VDC coil of the starting system of a car was implemented as a main element for he generation of high voltage. It was determined that the energization of the fence is not constant but by pulses and so an Arduino UNO pulse generator was implemented together with a power interface based on transistors. It was used GSM/GPRS technology with Shield SIM900A to generate the alert system via text messaging on mobile phones. For the evaluation of the fence violation, sensors for end stop signals adapted with a spring were employed combining the physical phenomenon tension. A fence of mobile type was built with pigtail stakes and polyelectric thread for the experimentation in the field of the prototype. The use of solar energy was chosen to create a self-sustaining system, and for the selection of the photovaluate system components, the currents method was used. In which it was determined that the global system has a consumption of 245 Ma and within this consideration a panel of 50Wp was selected, a regulator of 12 Vdc of 10 A and a battery of 40Ah. Additionally, a remote monitoring system was created based on Zigbee techonology with Xbee S2 modules for wireless communication and the monitoring console was implemented in QT Creator with Phyton on a Raspberry PI3. The optimum performance of the system evaluated in the field was obtained, integrating the control and monitoring part, marking it a complete system. KEYWORDS:
