一种跨网闸数据传输系统的设计与实现

Design and Implementation of An Across Netgap Data Transmission System

电力系统生产环境下,不同安全区域间的数据传输有着严格的要求,一方面保障了生产环境的安全,另一方面又给数据传输和共享带来制约。设计并实现了一个基于网闸的数据传输系统,可以将结构化数据序列化后传输,在UDP传输协议的基础上自定义了通信协议,保障了通信的实时性和数据的完整性,整个过程中不产生任何磁盘文件。对于各种不同结构的数据传输需求,只需要改变序列化和反序列化模块,系统具备通用性。该系统已经部署到某发电企业的数据采集现场,实际运行结果验证了该系统的稳定性和可靠性,替代了原先的文件搬运方式,解决了频繁读写磁盘导致的系统故障。

Under the environment of power system production, there are strict requirements on the data transmission between different safety areas. On the one hand, it ensures the safety of the production environment,on the other hand, it also brings the restriction of data transmission and sharing. Design and implementation of a netgap data transmission system, which can serialize structured data is conducted. By designing a custom communication protocol based on the UDP transport protocol, real-time communication and data integrity can be guaranteed. Also, the whole process does not produce any disk files. For the data transmission requirement of different structure, it only needs to change the serialization and deserialization modules,so the system has the versatility. The system has been deployed to a power plant on the data collection spot,instead of the original file handling way. It proves that the system has the stability and reliability, and system failure caused by frequently reading and writing disk has been solved.
