Abstract: This invention relates to a method for making 32-bit addressing of SV data by utilizing FPGA, which may be applied to processing digital sampling data in an equipment of an intelligent substation. Specifically, the method includes the following steps: FPGA receiving naked SV data packages generated based on IEEE802.3 standard; analyzing data structure of Ethernet frame; based on characteristics of the Ethernet frame of the SV data, the SV data of the network byte sequence being reorganized by utilizing ASN.1 coding rules, so that the SV data being converted into a data that can be directly accessed by 32-bit addressing processors. As a result, SV data decoding efficiency is improved greatly. This invention may make the decoding efficiency of 32-bit addressing processor improved by 5-10 times, thus solve problem of declined efficiency due to processing network byte order by splitting and reorganization.

Abstract: An anti-interference switch signal transmission circuit, in which a changeover switch is used at a signal terminal, is disclosed. A normally closed contact is connected to DC?, a normally open contact is connected to DC+, and a common contact is connected to a switch signal acquisition circuit. When no signal exists, DC? is provided to a positive input terminal of the switch signal acquisition circuit via the normally closed contact. Since a negative input terminal of the switch signal acquisition circuit is also connected to DC?, even if interference is caused, no false signal is generated. When a signal exists, the position of the changeover switch changes and DC+ is connected to DC? via the closed normally open contact through the switch signal acquisition circuit thus a loop is formed, so that the signal can be detected.

When a signal exists, the position of the changeover contact changes and DC+ is connected to DC? via the closed normally open contact through the switch signal acquisition circuit thus a loop is formed, so that the signal can be reflected. The interference problem is solved by connecting both the two terminals of the acquisition circuit to DC? when no signal exists.
