Intelligent power system fault recorder

Abstract

An intelligent power system fault recorder comprises a data acquisition unit and a data management unit, wherein the data management unit and the data acquisition unit are communicated through the Ethernet. The data acquisition unit comprises a plurality of signal acquisition control modules, and each signal acquisition control module comprises a signal conditioner, an A / D conversion module, an optoelectronic isolation circuit, a GPS synchronous clock, a wireless communication module, DSP data processing panel and an Ethernet interface circuit. The data management unit comprises a main control chip ARM, a Flash interface circuit, an SDRAM interface circuit, an Ethernet interface circuit, a hard disk interface circuit, a serial port communication interface circuit, a touch screen interface circuit, a JTAG interface circuit, a USB interface circuit and a wireless communication module. The intelligent power system fault recorder solves the problems that all former fault recorders form a network difficultly, are incapable of being mounted in a scattered mode, and large in size of the system, and the intelligent power system fault recorder improves running speed, stability performance and communication capacity.

Description

technical field [0001] The invention relates to an electrical signal recorder, in particular to a power system fault signal recorder. Background technique [0002] At present, domestic fault recorders mostly use microcomputer type recorders. This kind of fault recorder adopts the front and back mode. Wave recorders have deficiencies in data synchronous acquisition, data communication, and flexibility. Due to the large size of each fault recorder system, there are differences in operating speed, stability, and communication capabilities, and networking is difficult and cannot be realized. Decentralized installation is also not possible. With the development of digitization and networking of substations, the traditional microcomputer-based fault recorder can no longer meet the requirements. Contents of the invention [0003] The object of the present invention is to provide an intelligent power system fault recorder for solving the above technical problems. [0004] An in...
