Network type electric black box

Abstract

The invention discloses a network type electric black box suitable for automatic power distribution systems, belonging to the technical field of data collection and comprising a power supply module, amicrocontroller module, a communication module, a display module, an upper position machine configuration program and the like, wherein the power supply module is used for supplying power to the microcontroller module and the communication module; the microcontroller module uses an embedded processor ARM9 as the core and has a memory FlASH of an outer extension program and a data memory SDRAM; the communication module has a plurality of different communication ports, and the display module is used for displaying the current running state of a system. The electric black box connects various data collection terminals by RS-485 and RS-232 ports in a hanging mode, realizes the communication with an upper position management unit by Ethernet, CDMA / GPRS / GSM and the like, has abundant data transmission modes, flexible configuration and good automatic management and can individually run free from the upper position machine.

Description

Technical field [0001] The invention relates to a network type power black box suitable for a power distribution automation system, and belongs to the technical field of data acquisition. Background technique [0002] With the gradual deepening of reform and opening up and the gradual marketization of electricity, the contradiction between power supply and demand gradually tends to balance. Under this background, user demand has changed from "power use" to "high-quality, high-reliability power energy use. ", and then put forward the demand for power supply quality and power supply reliability requirements. Distribution network automation has emerged as an important technical means to achieve the above goals. [0003] The distribution automation system (Distribution Automation System, abbreviated as DAS) is an automation system that enables power distribution companies to monitor, coordinate, and operate power distribution equipment in a real-time manner from a distance. Its conte...
