| 摘 要： | 赤大白(赤峰-大板-白音华)铁路,北起西乌旗白音华煤田,南至内蒙古赤峰市,全长361Km。根据赤大白铁路设计要求,需要在阿山河大桥、灰通河大桥、塔拉索河大桥及红卫车站设计、安装CAWS600-R自动气象站,为机车的安全运营提供准确的气象保障。为此,我们为该部门在距赤峰市300Km以外的阿山河大桥、灰通河大桥、塔拉索河大桥及红卫车站设计、安装了4套CAWS600-R自动气象站。由于上述3桥1站处于偏远地区,不具备GPRS无线传输条件,所以我们利用SRX单板(子速率接口板)将CAWS600-R自动气象站数据采集器输出的9.6kbit/s数据复用到铁路沿线现有的64kbit/s数字通道上,实现气象资料的远程传输。

| Abstract: | Chi-Da-Bai（Chifeng-Daban-Bai Yinhua） Railroad,which is from Xiwu Banner Bai Yinhua coal field in Xilin Gol League to Chifeng of Inner Mongolia,it＇s overall length is 361km.According to Chi-Da-Bai railroad design requirement,it needed to design and install four sets of CAWS600-R automatic weather station in the Ashanhe bridge,the Huitonghe bridge,the Talasuo bridge and the Hongwei station from outside Chifeng 300km for providing the accurate meteorological support for the security operation of locomotive.Because the above three bridges and one station are in the remote districts,it does not meet the GPRS wireless transmission requirement,therefore using the SRX veneer（sub-rate to meet oral plate） to let CAWS600-R the automatic weather station data acquisition output 9.6kbit/s data multiplying to the rail line existing 64kbit/s digital channel,realizing the meteorological data long-distance transmission. |
