中文摘要：

根据AISG2.0协议对多频段电调天线（Multi-band Remote Electronic Tilting Antenna,MRET）中状态监控、倾角调节和故障告警等技术要求,设计了符合协议规范的MRET嵌入式控制单元。首先给出了控制单元的硬件系统结构,然后详细介绍了通信接口电路、浪涌电流抑制电路和下倾角控制电路。软件设计部分介绍了协议栈、下倾角控制模块的设计思路,并详细阐述了固件更新功能的实现方法。测试和实际应用证明,该设计方案在电气性能和协议完整性等方面符合AISG2.0的规范要求,且具有兼容性好、长期运行稳定可靠等优点。

英文摘要：

According to AISG2.0technical requirement on Multi-Band remote electronic tilting antenna（MRET）on state detection,modifying tilt angle and alarm reporting,embedded control unit of MRET conforming to AISG2.0was designed.The hardware system diagram was given first,then the communication interface,inrush current suppression circuit and tilt angle driver were discussed.In software module,the idea of protocol stack and tilt angle detection and control function was proposed,and the design of firmware download and activation was provided in details.Application results show that the proposed design conforms to AISG2.0in the electronic performance and protocol integrity,and features its good compatibility and long-term stability.
