| 摘要: |
| 根据AISG2.0协议对带驻波检测功能的塔顶放大器（TMA）中状态监控、故障告警和数据通信的技术要求，提出了TMA嵌入式控制单元的设计及实现方法。硬件部分首先概述了总体设计方案，然后阐明了OOK（On-Off Keying）模块、可配置式电流告警电路、浪涌电流抑制电路和驻波检测功能的设计思路;软件部分详细介绍了AISG协议栈的设计方法，并给出了低噪声放大器（LNA）及驻波故障的检测流程。测试证明，本系统的电气性能、监控功能以及协议完整性均满足AISG2.0协议的要求，并完成了与主流基站系统厂家的互操作测试。 |

| Abstract: |
| According to AISG2.0 technical requirement for Tower Mounted Amplifier(TMA) with standing-wave monitoring function on state detection,fault report and data communication,the design and realization method are presented. In the hardware aspect,system diagram is given first,and then the on-off keying(OOK) module,configurable current alarm circuit,inrush current suppression and standing-wave measurement circuit are investigated. Implementation method of AISG protocol stack and low noise amplifier(LNA) and standing wave fault detection flow are discussed in detail. Test of electrical performance,monitoring function and protocol integrity shows that the present design scheme primely matches the requirement of AISG2.0,and interoperability test with major base station system supplier has been successfully accomplished. |
