摘 要: 工业现场对信息的传输具有高可靠、高实时性的要求。但工业厂区存在着仪器、仪表分布分散,设施位置偏僻,人工抄录费时费力等问题。另外,工业生产现场环境恶劣,干扰严重,对网络传输管理提出很大的挑战。因此,提出一种基于分层架构的网络管理模型。将网络分为不同的管理域进行分层管理。并采用基于移动代理技术的分布式管理方案,针对常规情况下和网络产生拥塞情况下,分别采取相应的管理方法。从而可以对网络进行有效管理,避免拥塞,保证信息传输的实时性和可靠性。 The information transmission has high reliability and high real-time demand in industrial field. There are some problems in industrial factories such as the scattered distribution of instruments, meters, remote facility location, and time-consuming when artificial transcribing. In addition, because of the harsh conditions and serious interference in industrial production site, it is a big challenge for the management of the network to transmit information. Therefore, a layered based network management architecture is proposed. The hierarchical network ~s divided into different management domains. With the distributed management scheme based on mobile agent technology, the corresponding management methods for the regular and network congestion situations are taken, respectively. Thus, the network can be managed effectively to avoid congestion, guarantee the real-time and reliability of the information transmission.
