Embodiment Construction
[0021] Below in conjunction with accompanying drawing, patent of the present invention is described further.
[0022] Please refer to figure 1 , The conventional industrial Ethernet switch is composed of four Ethernet interface modules, a data exchange engine module, a ring network protocol module, and two optical fiber interface modules.
[0023] Please refer to figure 2 , in order to allow conventional industrial Ethernet switches to access 10 / 100Base Ethernet data and RS232 asynchronous data at the same time, only the way of adding a serial port server is used to convert its 10 / 100Base Ethernet data interface to RS232 asynchronous data interface, which not only takes up 10 The / 100Base Ethernet data interface resource has not yet realized the logical isolation of 10 / 100Base Ethernet data and RS232 asynchronous data.
[0024] Please refer to image 3 , the Ethernet data and the asynchronous data of the present invention isolate and transmit the electric power Ethernet sw...

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.
Description
【Technical field】 [0001] The patent of the present invention relates to a power dedicated Ethernet switch for smart grids, in particular to a power Ethernet switch capable of realizing the isolation and simultaneous transmission of Ethernet data and asynchronous data. 【Background technique】 [0002] A large number of power intelligent terminals used in smart grid construction are equipped with 10 / 100Base Ethernet interface and RS232 asynchronous data interface. [0003] In power system applications, in order to realize the interconnection and communication between different electrical intelligent devices in harsh electromagnetic environments, the international standard IEC-61850-3 for substation automation systems must be used, which uses communication based on TCP / IP technology structure. It is also expected to be based on this standard in the upcoming implementation of distribution automation. In addition, it is well known that the TCP / IP standard has good interoperabili...
