Diseño e Implementación de un Prototipo Receptor RDS Utilizando un Ordenador de Placa Reducida, Que Opere en la Banda FM Comercial para Radiodifusora Rio FM.

Abstract

The present investigation is about the design and implementation of a RDS receiver prototype by means a reduced plaque computer running in a commercial FM band for radio station Rio FM located in Chimborazo province, Riobamba canton which took advantage the new technology to visualize data. Signal in the radio station was analyzed and it is in advanced period in order to give this added value. It was determined that the receiver would monitor the radio programming and let the emerging data visualization. A reduced plaque computer Arduino One was used for the development of the design and implementation which is connected to a receiver circuit to detect the signal in third harmonic established in 57 KHz. A display LCD was attached with control to handle around the receiver prototype and to optimize a programming algorithm in order to work under the laws and regulations established by National Telecommunications Council. It has demonstrated that in Ecuador it is possible to create new technological tools changing the productive matrix. Therefore, it is concluded that prototype runs adequately by receiving the signal and showing the data. This prototype runs in 99% while radio station encoder run in 50% because of a wrong setting made by suppliers who didn´t established which data can be visualized that is why a simulation in Magic RDS application was carried out to demonstrate a better performance of the receiver. It is recommended to the radio station to set up the encoder appropriately in order to receive this signal and to guarantee its reception and visualization of data.
