不同代际移动通讯技术对自动气象站数据传输支撑能力对比分析

Comparison and Analysis of Different Generation Mobile Communication Technology Supporting Capability of Automatic Weather Station Data Transmission

随着移动通讯技术的不断推进,第四代移动通讯技术(4G)逐渐取代2G,成为黔南州主流的移动通讯技术。在此背景下,2G的通讯信道带宽不断变窄,对黔南州区域自动气象站传输及时率(以下简称传输率)的负面影响不断变大。为全面分析4G和2G通讯模式对传输率的影响情况,黔南州气象局组织技术人员开展传输率外场对比试验。结果表明:4G通讯模块和通讯卡的应用能够较大幅度的提升传输率;而且采用4G通讯模块和通讯卡时传输率极值的波动范围比采用2G时更窄,传输更加稳定。在相同的设备、通讯环境和天气状况下,采用4G通讯模块和通讯卡时的传输率绝大部分时间均优于2G,且不管是在冬季,还是在初春,4G模式对数据传输的支撑能力均体现出一致的稳定性。

Thanks to the expansion of mobile communication technology,the fourth generation mobile communication（ 4 G） gradually replaced the second generation of mobile communication technology（ 2 G）. It has become a mainstream in Qiannan prefecture. The communication channel bandwidth of 2 G is constantly narrowed,and the negative influence of transmission rate of automatic weather station in Qiannan prefecture is also increased. In order to compare 4 G and 2 G communication modes on the transmission of automatic weather stations,the meteorological department of Qiannan state has conducted a comparative experiment on the transmission rate. The results show that the application of 4 G communication module and card can greatly enhance the transmission rate. Moreover,the fluctuation of transmission rate extremum of 4 G communication module and card is narrower than that of 2 G,and the transmission is more stable. In the same equipment,communication environment and weather conditions,the transfer rate of 4 G communication module and the communication card is better than 2 G. in addition,no matter in winter,or in the early spring,4 G model shows consistent stability on the data transmission.
