Abstract
The invention relates to a power Ethernet switcher for realizing Ethernet data and asynchronous data insolated synchronous transmission. A conventional industrial Ethernet switcher comprises a STDM module, a TDM module and a serial port module, besides an Ethernet interface module, a data exchange engine module, a looped network protocol module and an optical fiber interface module. Due to the adoption of the switcher, an RS 232 asynchronous data interface additionally provided besides an optical fiber interface and a 10/100-based Ethernet data interface which can be provided by a conventional industrial Ethernet switcher. Therefore, the switcher realizes the logically insolated isolation of 10/100-based Ethernet data and RS 232 asynchronous data. Therefore, the 10/100-based Ethernet data transmission of a conventional industrial Ethernet switcher is realized, while the RS 232 asynchronous data transmission, which is safe, reliable and real-time, can be realized at the same time. According to the invention, the drawbacks of the industrial Ethernet switcher when being applied in the power industry are solved, and the needs of various power intelligent terminals in digital transformer substations and distribution network automation systems for access to 10/100-based Ethernet data and RS 232 asynchronous data in intelligent power grid construction are satisfied.
