The principle of data acquisition has been applied in the industry

Data acquisition, also known as data acquisition, uses a device that collects data from outside the system and inputs it to an interface inside the system. Data acquisition technology has been widely used in various fields.

Data collection has a wide range of meanings, including the collection of continuous physical quantities of the surface. In computer-aided drafting, mapping, and design, the process of digitizing graphics or images can also be referred to as data acquisition. At this time, geometric quantities (or physical quantities such as gray scales) are collected. Acquisition is generally a sampling method, that is, repeated acquisition of the same point data at a certain time (called sampling period). The collected data is mostly an instantaneous value, or it is a characteristic value for a certain period of time.

Accurate data measurement is the basis of data collection. Data measurement methods are contact and non-contact, and the detection components are various. Regardless of the method and components, the premise of not affecting the state of the object under test and the measurement environment is to ensure the correctness of the data.

The data acquisition system is a flexible, user-defined measurement system that combines computer-based measurement hardware and software products. The purpose of data acquisition is to measure physical phenomena such as voltage, current, temperature, pressure or sound. PC-based data acquisition, measured by a combination of modular hardware, application software and computers. Although data acquisition systems have different definitions for different application needs, the purpose of each system to collect, analyze, and display information is the same. The data acquisition system integrates signals, sensors, actuators, signal conditioning, data acquisition equipment and application software.

Today, the widespread use of computers, the importance of data collection is very significant. It is the bridge between the computer and the external physical world. Data acquisition tools mainly include data acquisition cards, data acquisition modules, data acquisition instruments, cameras, and microphones.
