| China is a big fishery country. Large number of people engage in fishing. To keep the fishermen’s life and property safe reliable marine fishery communication system is needed. But in our country fishery communication is relatively backward, is unable to meet the needs of modern fishery production, management and safety rescure. In this dissertation, a new remote control system for full digital fishery ultrashort wave radio base stations is designed and implemented by using the latest Linux embedded technology development platform. So a stable and reliable communication system for fishermen is built to provide all-weather communication support.In this dissertation, we first introduce the function, performance characteristics and system architectureof all digital base station in SX08series fishing radios. Based on these, we then propose a remote control scheme of local base station by using TCP/IP protocols and IP technology. We also analyze the design principle and methods of the remote control system. Thirdly, we introduce the develpement platform of the embedded system and related software and hardware, embedded Linux operating system and the related protocols and key technologies for developing remote control system which include Socket programming, TCP protocol, UDP protocol and multithread technology in remote control system. Fourthly, we introduce and analyze the framework of the remote control system, the server-side speech communication, signaling communication and the related functions.Test results of the prototype show that its function has been fully realized, its performance characteristics meet with the design requirement and it has reliable function and stable performance. |
