摘要: 为了解决兰州重离子加速器研究装置(HIRFL-CSR)磁铁电源数字调节器的通讯堵塞问题,采用了新的体系架构,并将P2P技术嵌入到数字调节器的核心控制器ARM中,运用UDP的打洞技术,使调节器之间的数据不再通过中心Oracle数据库转发,而是在调节器间直接建立通讯,这种方式分散了中心Oracle数据库的通讯量,减少了网路堵塞的风险,提高了通讯的效率、有效性和可靠性。Abstract: In order to solve the communications blockage problem of the power supply digital adjustors in Lanzhou Heavy Ion Accelerator CSR, a new system architecture is adopted, P2P technology is embedded to the core processor ARM of the digital adjustor. Based on the technology of UDP holing, a direct communication connect is established between the adjustors, thus the data are no longer forwarded by the main Oracle database system acting as a server. This method decentralizes the communication responsibility of Oracle database system, the risk of network block is reduced, and the effectiveness and reliability of communication is improved.
