Virtual Instrument Development

With the increase of market demand, the instrument is also continuously progressing. The main functions of the measuring instrument are composed of three parts: data acquisition, data analysis, and data display.

In the virtual reality system, data analysis and display are completely completed by the PC software. Therefore, as long as the additional data acquisition hardware is provided, the measurement instrument can be composed with a PC. This kind of PC-based measuring instrument is called a virtual instrument. In the virtual instrument, using the same hardware system, as long as the application of different software programming, you can get completely different measuring instruments. It can be seen that the software system is the core of the virtual instrument and the software is the instrument.

Traditional intelligent instruments use some sort of computer technology in instrument technology, while virtual instruments emphasize the absorption of instrument technology in general computer technology. The software system at the core of the virtual instrument is versatile, popular, visual, extensible, and scalable, and it can bring great benefits to users. Therefore, it has the application prospect and market that traditional intelligent instruments cannot match. .

Intelligent instruments are the combination of computer science, electronics, digital signal processing, artificial intelligence, vlsi and other emerging technologies and traditional instrumentation technologies. With the development of related technologies such as application-specific integrated circuits and personal instruments, smart instruments will be more widely used. The single-chip computer technology, which is the core component of smart devices, is the driving force for the development of smart devices in the direction of miniaturization, multi-functionality, and more flexibility. It can be expected that smart instruments of various functions will be widely used in various fields of society in the near future.

With the rapid development of network technology, internet technology is gradually infiltrating into the field of industrial control and intelligent instrumentation system design. The intelligent instrumentation system is based on internet-based communication capabilities and remotely upgraded and functionally-redesigned intelligent instrumentation systems. And system maintenance.

In-system programming (iSP) is a state-of-the-art technology that modifies, configures, or restructures software. It is a kind of first proposed by lattice semiconductor company that allows us to carry out every link in the product design and manufacturing process, and even after the product is sold to end users, it has the logic and function of its devices, circuit boards or the entire electronic system at any time. The latest technology for configuration or reorganization capabilities. The isp technology eliminates some of the limitations of traditional technologies and connection flaws, and is conducive to board design, manufacturing, and programming. Isp hardware is flexible and easy to modify software to facilitate design and development. Since isp devices can be handled on a printed circuit board (pcb) like any other device, programming isp devices do not require specialized programmers and more complex processes, as long as they are performed via a PC, an embedded system processor, or even an internet remote network. Programming.

The embedded micro-internet Internet connection technology was proposed by Emware Corporation when it created the eti (extend the internet) expansion of the internet alliance. It is a technology for accessing embedded devices such as SCMs to the internet. Using this technology, it is possible to connect 8-bit and 16-bit microcomputer systems to the internet to implement remote-based data acquisition, intelligent control, and upload/download of data files.

Currently, connectone, emware, tapeking, and domestic p&s companies all provide internet-based devices, networking, software, firmware, and hardware products.
