Can Receive Rds Radio Software Design

At present, it is not very popular for the broadcasting station with RDS in our country, but many countries of America and Europe are already very popular in using the RDS technique. So the study for the design about RDS project is very imperative under the situation for keeping up with the international development.The article expounds the theory of making use of frequency modulation to transmit the data. and signal. It places emphasis on introducing the software of incepting the audio signal and the RDS information. The software of the general radio only takes over and plays the audio signal. The software in the article not only can incept the audio signal but also the data, and can deal with the data and display them. The user is clear at a glance for some important information. It makes up for the defect of the general radio only with audio signal.The design of the software is based on the mature hardware of KWANG SUNG company and compiled with C51. CPU is the series of 8052. For designing the software of the radio with RDS, it is necessary to comprehend the development of the wireless and the sending&incepting of the signal and to understand the sending mode and encoding rule of RDS.It is the most important for the software of the general radio that it can exactly check if the frequency has the audio signal. Add all kinds of the functions about the radio after I finished the basic function. For example, the function of directly inputting frequency, the function of auto-searching broadcasting station, the function of manual-searching broadcasting. station, the function of memorying broadcasting station, the function of clearing away one broadcasting station, the function of clearing away all broadcasting station. For RDS. compile the software of right incepting the data of RDS, then deal with the data for displaying them on the screen.It is used for all kinds of home machines after completing all of the design of the software. The software can be used for all kinds of home machines of varied districts after lots of test and modifying. Thus the design of the software is perfectly completed.Chapter i is prelude. It briefly introduces the general radio and RDS, then argues the importance of the design of the software with RDS. Chapter 2 introduces the common sense of the wireless. Chapter 3 introduces the technique of RDS in detail. Chapter 4 introduces the used hardware. Chapter 5 introduces the design of the software for the general radio. Chapter 6 introduces the design of the software for RDS. Chapter 7 summarizes the work of the article.
