Instrument technology 1.0 and instrument technology 2.0 compare components and essential elements, the concept of virtual instrument technology has been widely recognized and adopted in the market, and the factors driving its progress are still developing.

Therefore, of course, virtual instrument technology will continue to gain new leap: hardware, data converter (ADC), data bus / bus architecture and processor technology are indispensable; in terms of software, LabVIEW graphical programming environment has become increasingly The most common application tool.

First look at the ADC. In the past, engineers needed to design their own dedicated ASICs or off-the-shelf high-performance ADCs. But it is clear that the cost of ASIC solutions is higher for test and measurement industries with relatively small shipments. As ADCs continue to enter more applications, semiconductor vendors have seen tremendous growth in this technology. Today, ADC not only provides sufficient performance, but also achieves low cost advantages due to mass production.

Followed by bus technology. In fact, many bus technologies have "double high problems" - while providing high bandwidth, latency is also high. Unfortunately, the delays that are often overlooked in most cases have a direct effect on some test applications, affecting the speed of the instructions between the bus nodes. In addition, a variety of buses still have a variety of requirements. For example, Gigabit Ethernet has a high transfer speed, but every time you change it, you need to rewrite the software; GPIB doesn't have this kind of trouble, but you need to buy a controller... and so on. "This makes the PCI/PXI bus that excels in both bandwidth and latency easy to win. The widespread adoption of the PC industry has demonstrated the superiority of the technology," said Zhu Jun.

Multi-core processor technology is also a booster for instrument technology development. As the computing carrier of application software, the processor has become the core device of next-generation instrument technology. The competition between AMD and Intel's two major processor vendors has made processor performance steadily follow the pace of Moore's Law. Intel also announced plans to introduce an 80-core processor in 2011, which will provide terabytes of computing performance. Obviously, the future of the processor is multi-core.

Zhu Jun pointed out that compared with the 1.0 method, the instrument technology 2.0 method has very high requirements for software. In order to fully integrate the above hardware technologies, a powerful application software must meet the following requirements: Provide powerful analysis capabilities - including development connectivity between the built-in analysis library core and third-party software tools; allowing users to freely choose the most suitable requirements The bus - supporting a variety of bus technologies; in order to take full advantage of the advantages of multi-core processors - support engineers to efficiently program multi-core processors, the need to develop a new compiler to solve the development challenges of parallel architecture.

LabVIEW already has the above capabilities. Different from the characteristics of PLC configuration software and C text language, this is a graphical programming software platform. Since its introduction in 1986, LabVIEW has added an out-of-the-box analysis function that now includes more than 500 built-in math, signal processing, and analysis functions for order analysis, modulation, spectrum analysis, and advanced signal processing. Additional kits. In addition, with the m-file text syntax provided by MathScript, engineers can choose a more efficient syntax. The software not only supports all bus technologies and various operating systems, but also supports the Vista operating system in 8.2.1 released in April this year (LabVIEW can be configured at the bottom). In addition, on last year's NIDays, NI also automatically deployed two parallel programs to a dual-core processor for demonstration.

Zhu Jun pointed out that almost all programming software is a serial architecture, and LabVIEW is a parallel architecture programming software. "If there are multiple parallel loops in the program, LabVIEW automatically assigns tasks among the multicores," she said. "From single-core to multi-core, users can enjoy the benefits of multi-core technology without changing the code."

“Although different industries have different development paths, the common point is that users are becoming more and more common in custom requirements.” Zhu Jun concluded, “Instrument Technology 2.0 has become an imperative trend in the test and measurement industry, with software. The core, combined with modular hardware solutions will enable engineers to achieve the customization and optimization results they need."
