Power generator excitation system data collecting instrument based on ARM (advanced RISC machine)

Abstract

The invention relates to a power generator excitation system data collecting instrument based on an ARM (advanced RISC machine). The power generator excitation system data collecting instrument is characterized by comprising an ARM processor, wherein the ARM processor is connected with a storage unit, at least one path of interface is outwards expanded from the ARM processor, the path of interface is connected with excitation equipment through a MODBUS bus, and the ARM processor is also connected with an industrial Ethernet interface. The power generator excitation system data collecting instrument has the main function of collecting data of power generator excitation equipment, and the data is sent to a remote data center through the Ethernet for being used for analysis, prediction and fault diagnosis. The power generator excitation system data collecting instrument also has another function of providing a black box recording function. A concrete measure comprises the steps that when the power generator excitation system fails, the power generator and the excitation information is recorded in real time, and is stored into a local SD (secure digital) card to be used for later-period analysis.

Description

technical field [0001] The invention relates to an ARM-based excitation system data acquisition instrument, which belongs to the front-end acquisition part of the big data of the generator excitation system. Background technique [0002] In recent years, the concept of industrial big data has gradually been accepted by the industry, which has led to a new round of technological development of industrial equipment. A typical application of industrial big data is product fault diagnosis and prediction, which can be used for product after-sales service and product improvement. The data of the equipment is collected by the sensor and sent to the remote data center with the help of Ethernet technology. The data center can analyze the received information and make diagnosis and prediction of product failure. [0003] The traditional excitation system only has some simple data display or indication signals on the equipment, which plays a very limited role in the failure prediction...
