In human production activities and scientific experiments, in order to understand and master the progress of the whole process and its final results, it is often necessary to check and measure various basic parameters or physical quantities, so as to obtain the necessary information, and use it as the basis for analysis and decision making. It can be considered that the detection technology is a series of technical measures taken by people in order to understand the information contained in the measured object qualitatively and master it quantitatively.
With the human society entering the information age, the detection technology with information acquisition, conversion display and processing as the main content has developed into a complete technical discipline, which plays an important role in the broad field of promoting production development and scientific and technological progress. Testing technology has been applied to almost all industries, it is a comprehensive application of multidisciplinary knowledge. It involves semiconductor technology, laser technology, optical fiber technology, voice control technology, remote sensing technology, automation technology, computer application technology, as well as mathematical statistics, cybernetics, information theory and other modern new technology and new theory.

A generalized detection system generally consists of an excitation device, a test device, a data processing and recording device, as shown in Figure 1.
Although there are many types and models of modern testing instruments and detection systems, and their uses and performance vary greatly, they are used for the detection of various physical or chemical components and other parameters, and their component units can be distinguished according to the signal transmission process.
As shown in Figure 2: First, usually by a variety of sensors (transmitters) to convert non-electrical measured physical or chemical parameters into electrical signals, Then through the signal conditioning (including signal conversion, signal detection, signal filtering, signal amplification, etc.), data acquisition, signal processing, signal display, signal output (usually 4 ~ 20 m A, D/A The analog voltage, switching quantity, pulse width modulation (PWM, serial digital communication and parallel digital output, etc.) after conversion and amplification, as well as the AC and DC voltage regulated power supply required by the system and the necessary input equipment (such as toggle switches, buttons, digital dial dial, digital keyboard, etc.) constitute a complete detection (instrument) system
