Encrypted ring network switch system

Abstract

The invention relates to the technical field of switches, and particularly relates to an encrypted ring network switch system. The encrypted ring network switch system comprises a ring network switchsystem,an encryption system, a field reactive power compensation controller, a single chip microcomputer control GPRS communication management module and a server upper computer; an analog interface of a user interface on a user line side is a Z interface, a Z1 interface is used for connecting the user line of a single user; Z2 and Z3 interfaces are used for connecting an analog remote concentrator and an analog PABX; the analog interface of a relay interface on a relay line side is a C interface, C11 accesses an FDM carrier transmission system through a path conversion device, and C12 accesses a four-wire transmission line through an analog repeater; a terminal uses a DSP-based reactive power compensation controller, and the controller is installed on a ring network site for collecting and monitoring communication parameters of a ring network, analyzing, calculating and collecting data, automatically performing an encryption operation, actively sending alarm information in the case ofabnormality and storing operation data information at the same time. The encrypted ring network switch system provided by the invention has a simple structure, higher transmission efficiency, and realizes intelligent control of the single chip microcomputer.

Description

technical field [0001] The invention relates to the technical field of switches, in particular to an encrypted ring network switch system. Background technique [0002] Fast ring network is a high-speed redundancy technology developed for Ethernet. This technology can not only ensure that the communication can be restored within 300 milliseconds when the network encounters a fault (when applied to more than 20 switches), it can also send an alarm through the error relay, indicator light or SNMP when the ring network link is disconnected. Once the ring network is disconnected, the indicator light will send an alarm on the disconnected switch, activate its status relay, and feed back the error information to the user through SNMP. A ring network uses a continuous ring to connect each device together. It ensures that the signal sent by one device can be seen by all other devices on the ring. The ring network redundancy refers to whether the switch supports the cable connecti...
