The test and measurement and instrument industries are the necessary guarantees for national defense equipment, as well as the cutting-edge technology for R&D. At the same time, it is an important link that any electronic technology cannot avoid. However, regardless of the needs of national defense or civilian use, the test systems and test instruments that we come into contact with are all imported brands without exception in high-performance applications.
According to statistics, the test instrument industry accounts for only about 2% of the output value of the electronics industry, while the output value of the electronics industry accounts for only about 2% of the world's total output value, but the added value brought by new technologies driven by test instruments can account for 70%. %-75% of the world's annual added value. As a basic product and technology that applies throughout the basic research to the production line, the strength of the electronic test instrument industry can completely drive the added value of a country's innovation.
As a high-tech, capital-intensive industry that spans multiple disciplines and emphasizes years of technology accumulation, our gap in testing instruments with foreign companies is comprehensive, not only lack of technology, experience and funding, but more importantly Differences in the direction of concepts, standards, concepts, etc., and insufficient attention to decision-making.
The gap between ideas and thinking is not the same thing as smoothing the gap in technology. However, compared with the technical gap, the gap between our ideas and thinking on the test instrument seems to be easy to solve, but the actual implementation is more difficult to face and more critical than the technical gap. The test equipment is a capital-intensive company. The scale of production of the company is very important, and the test equipment is a relatively small market. Because there are many kinds of instruments, the market for a single instrument type cannot be large. This has made it even more difficult for Chinese companies to catch up.
On the one hand, as a technology-intensive and accumulating industry, in the face of so many foreign competitors who have already taken a lot of lead, it is necessary to have enough investment in the test equipment to become bigger and stronger, and do not expect a return in the short term. Undoubtedly, relying on some private companies is difficult to have such a strong financial support.
Therefore, we must have the national strategic planning and strong support of relevant resources before we have the opportunity to continuously narrow the gap. It can be said that if the test equipment companies cannot achieve a relatively large scale, it will be difficult to have the strength of the international giants, and the growth in the previous period will require huge long-term capital investment.
On the other hand, because the market is not large, it is even more important to emphasize the continuity and focus of R&D of enterprises. For private companies in China, they face the pressure of survival. For many state-owned research institutes, they also Faced with the research of income-generating indicators and various cutting-edge topics, it is impossible to concentrate on intensive cultivation of one or two types of products, and refine products with ten years of experience. In today's experience and lack of understanding of the test, if we do not calm down and make a few good products, what do we have to compete with foreign companies?
Furthermore, because the market segmentation is complex, the short-term significance of the research on the structure and concept of the test instrument is difficult to realize, which makes some research institutions originally supported by the strategic countries to support the structure and concepts of their research and test instruments. Instead of focusing on this, we will pursue other tasks with better short-term benefits, which will result in the fact that only instrument manufacturers will develop these common basic concepts on their own, resulting in repeated waste of many R&D resources.
Another gap in the conceptual gap is the service. It can be said that as an industry with a gross profit margin of more than 50%, a large part of corporate sales profits are used to provide quality market cultivation, after-sales service and technical support. Especially in terms of the user's testing experience and training habits, the gap in the awareness of domestic companies is far worse than that of international companies.
A domestic test instrument manufacturer stated that they have similar product performance with foreign competitors, but the user interface UI and the generality of operations are far from one another, and the publicity among users is almost zero. When users have corresponding test requirements, even if the two products have completely different performance indicators, it is difficult for users to choose their products and give up foreign products. There is only one reason for users to use them.
Technical deficiencies. In these years, especially in the field of military testing, we have witnessed the prevalence of various bus technologies. However, whether it is the earliest GPIB, the later VXI, the current popular PXI or the irreconcilable LXI, or even the emerging AXIe bus All foreigners defined R&D, which means that if we want to apply these bus technologies, we will not be able to escape the test system architecture and test methods that they defined. On this basis, even if the bus standards are open, even if we In terms of hardware design, they have the same strength as theirs, but in the understanding of the bus technology, we still have deficiencies. The same technology we do have a gap in application, let alone, in most cases we have to buy their products To meet our test system requirements.
If we say that in these system-level test equipment, because of the open bus, our technology gap is relatively small, then in the field of desktop instruments, our gap is almost difficult to measure. For a basic test instrument, its architecture and concept are not difficult to understand, but we have a big gap between the specific function definition and the function realization of the product. Unable to define the function of the product and ensure that it can be achieved, this will make our test instrument development and application fall into an embarrassing cycle.
We cannot track the cutting-edge science and technology of advanced electronic technology, and there is no way to understand its testing needs. Naturally, we cannot develop test instruments suitable for the latest technologies for this purpose, so let alone grasp the pulse of the latest test market and earn the most lucrative. That part of the profits, and you can't come to test new advanced technologies, you can't catch the new technology when it comes out, people can't give you to meet the initial testing needs, so you can not understand the latest technology trends, It's also impossible to apply new technology to your test equipment. In this cycle, we have been unable to find a breakthrough, but we can only silently watch the new technology go through such a loop, and it is farther and farther away from cutting-edge technology and testing.
In defense and military testing, one of the more important problems that restricts the use of local test instruments comes from the lack of core semiconductor devices. We see that domestic test instrument companies, whether they are veteran state-owned research institutes or emerging private test instrument companies Compared with international giants, there is a very big gap between their own chip R&D capabilities.
It can be said that the test chip is difficult to find suitable products in the market because of its special requirements. Especially in signal analysis and signal acquisition, the lack of analog front-end technology and signal acquisition technology is directly reflected in our The test equipment could not capture some of the characteristic signals we needed, such as the vast majority of the needs of radar and microwave technology. The commercial chips could not meet their test requirements. As a result, our test instrument manufacturers did not know how to meet them. Instead, there are no related semiconductor devices that allow us to make products that meet these sampling rates and bandwidth requirements. These two points are precisely the preconditions for many signal analysis and signal processing in defense and military applications.
A pipe cutting machine shear, historically known as a lever shear and sometimes as a crocodile shear, is a metal-cutting shear with a hinged jaw, powered by a flywheel or hydraulic cylinder. Alligator shears are generally set up as stand-alone shears; however, there are types for excavators. They are generally used to cut ferrous members, such as rebar, pipe, angle iron, or I-beams.
