Research And Implementation Of Leaky Feeder Communication System Based On Digital Communication

The digital leakage communications system is a more advanced digitized system, is opposite complex and the huge systems engineering says in digitized mine such one, he has provided a very good solution to its effective correspondence; This article elaborated system's basic principle, component system's key constituent; Unifies the domestic and foreign existing design proposal, studied voluntarily has designed a set of mobile platform and the base station design scheme based on this system, and has carried on the careful explanation to its plan's layout.This article emphasis point is the research and the design for the mobile station and the base station of software and hardware in this system. And hardware's design and software's design complements one another, The hardware has designed the mobile station main circuit primarily by the C8051F340 micro processing chip, has realized voice of data acquisition, signal processing and transmission, filter and amplification of the function; use the combination of the Nordic companies producing the 905 RF transceiver and leakage of cable for wireless signal transmit and receive; Software's design carries on the operation through the IDE platform, has carried on the software control design to the corresponding part; Finally has entered the experiment and the test to the system to verify the performance of the system, and considered how to modulate the corresponding parameter to enable it to achieve the best effect, it is concluded that this system has the work movement to be stable, the data accurate reliable, easy to operate and so on characteristics.
