An Agricultural Information Transmission System Based on Smart Display Terminal and IOCP
We derive a new way that maximizes and optimizes the agricultural information transferred in rural areas in China. The focus of this paper is to design an agricultural information transmission system based on C/S (Client/Server) model and smart display terminal. Smart display terminal, with General Packet Radio Service (GPRS) module attached, sends application requirement message and a server with expert system that supply precise agricultural information response to the requirement. To ensure the server capabilities to process a large association pressure from many clients requests, an ideal model I/O Completion Port (IOCP) mechanism is applied that could buffer the clients pressures. In this paper, we apply the mechanism to solve the server pressure problem successfully and reduce the association pressures from many clients. We also shows that the mechanism is able to promote the efficiency of agricultural information transmission and often the smart display terminal is human-machine interface (HMI) adapted to rural areas in China.
