摘要
通过将云南FY-4/HRIT接收站数据接收流程嵌入现有CMACast数据接收流程,进一步优化流程,实现数据接收的主备切换,提高数据接收完整性和MICAPS4系统数据处理的时效性。结果表明,FY-4/HRIT接收站与CMACast的双通道主备数据传输处理的方式,能有效提高MICAPS4系统数据的可靠性,其时效比原来提高约2倍。
By embedding the data receiving process of Yunnan FY-4/HRIT receiving station into the existing CMACast data receiving process,the process was further optimized,the main and standby switching of data reception was realized,and the integrity of data reception and the timeliness of data processing of the MICAPS4 system were improved.The results showed that the dual-channel active and standby data transmission processing method of FY-4/HRIT receiving station and CMACast can effectively improve the reliability of MICAPS4 system data,and its timeliness is about 2 times higher than the original.
