Detection wave recording device in electric system and data monitoring method

Abstract

The invention relates to a detection wave recording device in an electric system and a data monitoring method. The data collection module of the detection wave recording device is orderly connected with a wave recording computation module and a wave recording management module; the data collection module monitors at least three types of sampling data signals; the data collection module saves different types of data interface real-time sampling values to form a sampling frame at the same moment point; the length of the sampling frame is decided by the configuration information configured by a user through the wave recording management module. The data collection module is submitted to the wave recording computation module to process after forming the sampling frame; the wave-recording computation modules caches and sends the sampling frame, and computes real-time waveform and performs fault judgement, transient wave recording and steady-state wave recording according to the sampling data type and sampling data length. The wave recording manager module is responsible for visualization and human-machine interaction. The user can configure the channel sampling data type and the sampling data length. And the problem that the existing electric system wave recording computation device is single in sampling data type and bad in sampling data accuracy is solved.

Description

technical field [0001] The invention belongs to the technical field of power systems, and relates to a power system data recording device, in particular to a detection and recording device and a data monitoring method in the power system. Background technique [0002] At present, most traditional power monitoring equipment monitors AD conversion data. The quantization bits of the AD converter itself determine the length of the monitoring data, and the common ones are 8bit, 10bit, 12bit and 16bit. With the rapid development of computer, electronics, automation, and communication technologies, signal data with higher precision other than AD conversion data appears in the power system, such as 32bit or even 64bit, which requires real-time monitoring, such as transmission through SPI and UART interfaces signal data. These types of signals are not compatible with traditional power monitoring equipment. If compatibility is simply achieved, there is still the problem of loss of a...
