Voltage signal acquisition and analysis system

Abstract

The invention discloses a voltage signal acquisition and analysis system. The voltage signal acquisition and analysis system comprises a first voltage signal acquisition module, a standard voltage signal acquisition module, a data analysis module, an MCU, a display, a cloud storage module, an alarm module, a network communication module and a PC. The first voltage signal acquisition module is usedfor collecting voltage signals to be analyzed in real time, and the standard voltage signal acquisition module is used for collecting standard voltage signals under the same condition with the voltage signals to be analyzed. The first voltage signal acquisition module and the standard voltage signal acquisition module are connected with the data analysis module in a communication mode. The voltage signal acquisition and analysis system is provided with the first voltage signal acquisition module, the standard voltage signal acquisition module and the data analysis module to enable the voltagesignal acquisition and analysis system to be able to make use of the standard voltage signals to help judge whether a first voltage signal is overvoltage or not; and the network communication moduleis arranged to enable the first voltage signal to be transmitted to the PC remotely, and the remote analysis and storage of the first voltage signals are facilitated.

Description

technical field [0001] The invention belongs to the field of analysis systems, and relates to a voltage signal acquisition technology, in particular to a voltage signal acquisition and analysis system. Background technique [0002] At present, in the process of using some circuits, the most important thing to pay attention to is the overvoltage protection. For the collection of voltage, some voltage sampling circuits are generally used at present, and the sampling circuit has an analog signal input, a control signal input and a Analog signal output. The purpose of this circuit is to receive an input voltage at a specified time and hold that voltage at the output until the next sampling begins. The sampling circuit usually consists of an analog switch, a holding capacitor and a non-inverting circuit with a unity gain of 1. Sampling works in one of the two states of sample state and hold state. In the sampling state, the switch is turned on, and it tracks the level change o...
