Embodiment Construction
[0029] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0030] The technical scheme of the invention strictly follows the functional specifications of the power dispatch automation system, and designs a method for real-time bus cross-safety zone communication. The technical solution of the present invention is mainly aimed at the communication between the I / II area and the III area with a physical isolation device.
[0031] Based on the characteristic that the isolation device only allows one-way transmission of data, in order to realize the message transmission of the real-time bus across security zones, it is necessary to increase the message forwarding program of the security zone and deploy it on the server connected to the network isolation device in each security zone . Hereinafter, the server deployed with the cross-security zone message forwarding program is called the transit server, the transit server connected...

The invention discloses a real-time bus across safety zone communication method suitable for power industries, and belongs to the technical field of informatization and automation of electric power systems. According to the real-time bus across safety zone communication method, across safety zone information exchange is accomplished through transit servers and internal nodes. Two transit servers are configured in one safety zone, and the transit servers are used for transmitting and receiving cross-zone messages and transferring the messages to a designated work catalogue, so that the internal nodes can use the messages. The transit servers are arranged at the positions related to an isolating device, the internal nodes in the same safety zone establish a network connection through a switch or a router, and the internal nodes are mainly used for transmitting messages and receiving messages at last. According to the real-time bus across safety zone communication method, data are transmitted through the network isolation device unidirectionally (in the forward direction and in the reverse direction) on the premise that the existing safety zone framework arrangement is guaranteed to be unchanged, and thus safe and stable data communication among different safety zones is achieved finally.
Description
technical field [0001] The invention belongs to the technical field of power system informatization and automation, and in particular relates to a method for real-time bus communication across safety zones. Background technique [0002] As we all know, the real-time bus can realize high-speed data communication between processes (processes between computers or within computers), and has functions such as process / node registration / revocation, message sending, message receiving, subscription, and publishing. These functions are provided to various applications in the form of interface functions to meet the requirements for real-time interaction of information between various applications. In addition, the bus supports one-to-many and one-to-one information exchange within the same site, among multiple security zones, or between multiple sites, creating a horizontal connection (that is, multiple The actual operating environment of vertical penetration (that is, between multipl...
