| Abstract: | Against the characteristics and requirements of data transmission in large-scale automatic weather station, this paper designs the dedicated GPRS data communication terminal unit and gives hardware design of the wireless data terminal. Detailed dial-up software process of the communication terminal is introduced and precautions of using MC35i module. Aiming at the existing problems of UDP protocol, a reliable UDP protocol is designed to improve UDP protocol, and working principle and data structures of the reliable UDP protocol is described. Finally, it introduces application of this module in the automatic detection system in Guangdong Province, and the reported rate is more than 99.7%. |
