摘　　要：在野外或城区,活动气象站点与总控站点之间一般距离较远,需要成本低且可靠的无线通信设备实现二者之间的数据传输。本活动气象站数传终端以C8051F022为微控制器,以SC16C2550B扩展MODEM口,连接无线数传模块SRWF1028和CDMA模块DTM228C,实现双信道可靠数据传输通信。嵌入式软件设计上采用实时设计模式中的分层模式,以达到移植和变动控制的目的。In rural and urban field, mobile weather stations are always far from the monitor station. Cheap and reliable wireless communication devices. Taking C8051F022 as the microcontroller, a data transmission terminal is designed for mobile weather stations. The terminal uses SC16C2550B to expand its MODEM ports to link wireless data transmission module SRWF1028 and CDMA module DTM228C,and implements the reliable and dual channel data transmission communication. Layered pattern of real-time design mode is used in embedded software design implement the port and alteration control.
