Design And Implementation Of Ir Interface Network Test System

Along with the arrival of the4G era, TD-LTE development has been of concern, as China has core intellectual property follow the evolution of TD-SCDMA technology. Ir interface as the interface of distributed base station between BBU and RRU, its standardization has a great impact on R&D of LTE test instrument, researching on Ir interface protocol conformance testing and has great significance of TD-LTE standardization and industrial.This paper proposes a technology solution of Ir interface chain networking test system based on Ir interface protocols, for application layer testing for Ir interface. This system supports Ir interface protocol upgrade and chain network scale expansion, with hardware equipment condition monitoring, testing and fault location function Ir interface application layer interaction process Ir interface network test platform.This paper analysis the functional requirements of the Ir interface network test system and designs the overall framework of the system, combined with the choice of hardware platform. In this paper a combination of modular and hierarchical design idea is used in the form of Chain network, the realization of the system is divided into device control module and network testing software, there has a detailed description of the two parts. In the design process, full consideration on the Ir interface protocol compatibility and upgrade support, achieve visual management Ir interface networking test system. Finally, this article completes the system test, including link connection test, heartbeat detection, interactive process testing and test record query test. The test results show that the Ir interface network test system test is completed properly and achieve the desired design goals.
