摘　　要：为了集成云、能见度、天气现象等新型地面自动化观测设备,中国气象局提出了硬件集成系统设计方案,文中主要解决硬件集成系统和计算机之间的通信。根据硬件集成系统设计方案,介绍了基于光纤以太网专用芯片(KS8995MAI)的多模以太网光纤收发器硬件设计方法,此收发器通过一对光纤可以将自动气象站数据、新型观测仪器等多种传感器数据经过光纤以太网统一发送到终端计算机。测试结果表明:方案实现了气象观测数据大容量、远距离的传输。In order to integrate the new ground automated observation equipments for cloud, visibility, weather phenomena, the CMA（China Meteorological Administration） proposed hardware integrated system design. In this paper, we mainly solve the problem of communication between the hardware integration system and computer. Accord- ing to the hardware integrated system design solutions, introduced the hardware design scheme of multimode Ethernet optical fiber transceiver based on special chip of optical fiber Ethernet（KS8995MAI）. This transceiver can transport a variety of sensor data such as automatic meteorological station data, new observation instrument by a couple of optical fiber, to the computer terminal via optical fiber Ethernet. Test results show that the scheme can realize the large-capacity and long-distance transmission of the meteorological observation data.
