A device for extracting characteristics of power signal acquisition based on arm architecture

Abstract

The invention discloses a power signal acquisition characteristic extraction device based on ARM architecture and belongs to the technical field of power supply characteristic testing. The device is designed to process a power characteristics parameter signal converted to + / - 10V through conditioning, and has functions of signal acquisition, and data reduction, storage, calculation and analysis. The hardware part of the device comprises six modules including a master control module, a power module, a transmission module, a signal acquisition module, a storage module and a display module, wherein the master control module is the core part of the power signal acquisition characteristic extraction device. The power signal acquisition characteristic extraction device achieves coordinated control and management of other modules by means of the master control module. The software part of the power signal acquisition characteristic extraction device comprises a communication protocol among various modules, shows a user interface and a data calculation and processing method. Codes are directly embedded into the core processing chip of the master control module through a compiler. The software part can be modified and customized according to user's requirements or fixed in a code module. Proper codes are compiled and embedded into the processing chip of the master control module according to different use requirements.

Description

technical field [0001] The invention relates to the technical field of power supply characteristic testing, and specifically, designs and develops a power supply signal acquisition characteristic extraction device based on an ARM architecture. Background technique [0002] The power quality characteristics have a very important impact on the electrical equipment. When the power quality characteristics are poor, the harmonics, pulses, or overvoltage, overcurrent, undervoltage, and undercurrent in the power supply will cause great damage to the electrical equipment. impact, and even cause irreparable damage to electrical equipment. Therefore, the detection of power supply characteristics is a must-test item stipulated by various standards such as national standards and national military standards. Especially for aircraft, ships, automobiles and other systems powered by generators driven by engines, the quality characteristics of their power supply need to be fully tested to e...

AI Technical Summary

Problems solved by technology

[0011] (1) The scope of application is small; for example, "multi-function signal acquisition instrument" and "switch signal acquisition system" can only be used to measure low-frequency signals whose frequency range does not exceed 1MHz, and the signal pattern and signal strength of the acquisition and measurement are different. with corresponding restrictions

[0012] (2) The function is relatively simple; for example, the "signal acquisition and driving test device" can only collect signals of specific styles and types, and can only drive and process specific drivers, and its functions are relatively single

[0013] (3) The degree of automation is not high, and the degree of technical completion and integrity is low; It is necessary to build a test environment according to the patent specification when using it, and the system must be reconfigured according to the test method according to the patent specification before it can be used

[0014] (4) There is no specific index requirement for test accuracy
