[Abstract]:In IT, there is a change every ten years, which has a huge chain effect on global business. Cloud computing is another important change in information technology. It is a new computing mode after grid computing. It has powerful data storage capacity and data business processing ability, and also has the advantages of economy and sharing. Therefore, the embedded data terminal for cloud computing mode will be favored by individual consumers. By analyzing the current situation and future development trend of cloud computing, this paper aims at the problems of limited storage capacity, low efficiency of data transmission and low utilization of funds in personal mobile data terminals. An embedded data terminal solution for cloud computing mode is proposed. The main research contents of this paper are as follows: (1) the basic theory of cloud computing is introduced, the service mode of cloud computing is expounded, the characteristics of cloud computing are summarized, and the development status of 3G network is briefly introduced. In this paper, the architecture of cloud computing is studied, and the related knowledge of embedded system is introduced. The main problems of mobile data terminal, the bottleneck of operation and the developing direction of mobile data terminal in the future are analyzed. Combined with 3G wireless network communication module, this paper puts forward the solution of embedded data terminal based on cloud computing, analyzes the 3G wireless network communication process and adds 3G module driver to embedded Linux kernel. In this paper, 3G wireless network communication between client and server is realized. (3) the network file system (NFS) is deeply studied, and NFS server is successfully installed on the virtual machine, and the virtual machine is used as the simulation cloud server. The embedded Linux development technology is studied, the embedded Linux development platform based on ARM9 is constructed, the cross-compiling environment is built. (4) the data transmission technology based on IP network is studied, and the client and server programs are designed. The embedded terminal system simulation model based on cloud computing is implemented. Finally, using the hardware platform and software platform, the server files are read and written in the client, and the client pictures are uploaded and downloaded through socket program. The simulation results show that the desired goal is achieved. And the cost of the whole embedded data terminal is lower.
