Automated terminal monitoring device for distribution network and monitoring system

Abstract

The invention relates to an automated terminal monitoring device for a distribution network. The automated terminal monitoring device is used for monitoring power distribution equipment and comprises a processor board card, an instrument transformer sampling board card and an input / output control board, wherein an instrument transformer detection input circuit is arranged on the instrument transformer sampling board card, and a processor module and an alternating current sampling circuit which are mutually connected are arranged on the processor board card; a switching value input / output conversion circuit is arranged on the input / output control board card. A hardware structure is divided in a board card way, and the board cards are communicated by a bus communication protocol, so that the integrated design of the traditional hardware is avoided, and the working efficiency and the maintainability of a system can be effectively improved. The invention also relates to a monitoring system based on the automated terminal monitoring device for the distribution network. Through a combined architecture mode, the networking monitoring mode is realized for a plurality of pieces of power distribution equipment, the interaction and communication between data of monitored power distribution equipment are realized, and the monitoring system can be suitable for various different monitoring requirements.

Description
