| Spanish abstract | La directriz del presente proyecto crear un sistema de adquisición y grabaciones de señales ́ısmicas que sea compacto, confiable y flexible para adaptarse a lasnecesidades de trabajar en estaciones de monitoreo volc ́anico y s ́ısmico. Paraalcanzar el objetivo se emple ́o el FPGA Spartan-6 LX45 como base del sistemaembebido de adquisici ́on continua de datos a velocidad configurable hasta 50 Ksps.Adem ́as el prototipo cuenta con comunicaci ́on v ́ıa Ethernet, 12 canales de ADC de24 bits expandible hasta 24 canales, almacenamiento de datos en memoria USB,interfaz amigable, indicador de informaci ́on en LCD y sincronizaci ́on de tiempoUTC mediante GPS externo. Como resultado del presente proyecto se obtuvoun dispositivo electr ́onico embebido para aplicaciones s ́ısmicas como: monitoreo,refracci ́on o reflexi ́on y aplicaciones para estudios vulcanol ́ogicos con antenas desensores, que adem ́as es compatible con softwares de visualizaci ́on y gesti ́on dedatos s ́ısmicos |
| English abstract | The guideline of the present project is to create a seismic digitizer. In order to beused as a seismic field station, the digitizer should be compact, reliable and flexibleto adapt at field seismic station. The objective was achieved using the Spartan-6LX45 FPGA as the basis for the embedded continuous data acquisition systemwith a configurable speed up to 50 Ksps. The prototype comes equipped withEthernet communication, 12 channels with 24-bit ADC resolution expandable upto 24 channels, data storage writable to both USB and SD, a user-friendly interface,LCD information indicator and time synchronization to UTC by external GPS. Asa result of the present project, an embedded electronic device was obtained that canbe utilized diverse seismic applications such as monitoring, refraction or reflectionand for use in sensor arrays appropriate for volcanic applications. The prototype iscompatible with visualization and seismic data management software |
