What's the difference between virtual instrument and traditional instrument?

First of all, the application of the two is different:

1. application of virtual instrument: virtual instrument is a measurement and control system composed of computer hardware resources and software for digital analysis and processing, process communication and graphical interface. It changes the way the instrument manufacturer defines the instrument function to the way the user defines the instrument function, that is, the instrument produced by the manufacturer is used in the traditional test. The performance and function of the instrument have been defined by the manufacturer before leaving the factory, and users can only choose and use it according to their own requirements and needs.

2. Application of traditional instruments: instruments have many uses and are very important scientific research tools and devices in scientific research laboratories and medical research and practice; With the continuous improvement of China's industrial automation level, the development and manufacture of various new instruments are rapidly progressing and updating, and are widely used in industrial production and process control.

Second, the overview of the two is different:

1. Overview of virtual instrument: Virtual instrument technology uses high-performance modular hardware combined with efficient and flexible software to complete various test, measurement and automation applications.

2. Overview of traditional instruments: Instruments refer to instruments or devices used for experiment, measurement, observation, inspection and drawing in science and technology. Usually a set of equipment or machines prepared for a specific purpose.

Third, the two have different meanings:

1, the meaning of virtual instrument: Virtual instrument technology is developed on the basis of PC technology, so it completely "inherits" the advantages of the latest commercial technology based on ready-to-use PC technology, including excellent processor and file I/O, allowing you to import data to disk at high speed and conduct complex analysis in real time. In addition, the continuous development of Internet and faster and faster computer network make virtual instrument technology show its more powerful advantages.

2. Significance of traditional musical instruments: Musical instruments are an important force to promote the construction of a harmonious society. Nowadays, problems such as global resource depletion and environmental pollution have become bottlenecks for the healthy development of society; Food safety problems, public emergencies, disease diagnosis and inflammable and explosive dangerous chemicals have brought serious impacts on people's lives. The solution of these main problems can not be separated from advanced detection technology and means.
