哈尔滨民航自动气象观测系统备份线路研究

Research on the hot standby routing of the AviMet~? AWOS in Harbin

民航气象自动观测设备是为气象人员、管制人员、航空公司提供机场跑道上的温度、湿度、风向、风速、场平面气压、雨量和RVR(跑道视程)等实时数据的设备,该设备需通过传输线路将数据传输到航管楼内的气象设备机房。目前,该设备的数据传输仅通过光纤路由实现。单一路由传输不利于设备的安全保障,可建立一套完全独立的双冗余备份传输系统来解决这一问题,以微波设备或无线网桥的无线传输作为光纤传输的备份,以期为哈尔滨民航自动气象观测系统备份线路传输提供安全保障。

The AviMet~?AWOS device provides real-time data on runway for the controllers,airlines and meteorologists,such as temperature,humidity,wind direction,wind speed,QFE and RVR(runway visual range).The device must transmit data to the meteorological device room in the control center by routing.At present,the data of the device is transmitted only by optical fiber routing;the single routing transmission has become the bottleneck of device security.The establishment of a double redundant backup transmission system is an urgent task to solve this problem.In this paper,the wireless transmission of microwave equipment or wireless bridge be used as the backup of optical fiber transmission to realize the guarantee of equipment transmission route.
