Problems solved by technology

[0003] At present, in the power system, the data conversion method between the dispatching center and the SDH transmission connection line is to first convert the Ethernet signal into RS232 data, and then convert it into E1 electrical signal through RS232 interface, and then convert it into optical signal through SDH optical terminal Transmission to the SDH transmission cable, the interface structure is complex and traditional, so it is necessary to study a more direct and simple interface solution in this field to solve the problem of interface conversion

Abstract

The invention relates to power dispatching telecommunication equipment suitable for an SDH (Synchronous Digital Hierarchy) transmission connecting line. The power dispatching telecommunication equipment is characterized by comprising a total dispatching server, the SDH transmission connecting line, a terminal processing device, a first interface conversion device and an E1 interface conversion device, wherein the total dispatching server is arranged at a main control station side; the SDH transmission connecting line is composed of a local-side optical transceiver and a station-side optical transceiver; the terminal processing device is arranged at a substation; the first interface conversion device is arranged between the total dispatching server and the SDH transmission connecting line; and the E1 interface conversion device is arranged between the SDH transmission connecting line and the terminal processing device. Thus, a summon mode with a new ear structure is provided, and an interface structure is simpler and more direct.

Description

technical field [0001] The invention belongs to a communication system for data transmission between a substation and a main control in a power substation system, and relates to a power dispatching communication device suitable for an SDH transmission connection line. Background technique [0002] The SDH optical transceiver has a large capacity, generally 16EI to 4032EI. SDH is a comprehensive information transmission network that integrates multiplexing, line transmission and switching functions and is operated by a unified network management system. It is a Synchronous Optical Network (SONET) proposed by the Bell Institute of Communications Technology in the United States. The International Telephone and Telegraph Advisory Committee accepted the SONET concept in 1988 and renamed it SDH, making it a general technical system not only applicable to optical fiber but also microwave and satellite transmission. It can realize multiple functions such as effective network manage...
