The development of modern instrumentation technology in China is facing difficulties

With the purchase of a Beijing vibrometer instrument factory, there are no more technically decent enterprises in the original instrumentation bureau. The masters who can engage in analog design are all more than 60. Their current working environment has not allowed themselves to take apprenticeships. , Retirement and high age have become a reality. Some elderly people who were able to kill the market and make sensors were also faced with the ability to develop such analog sensors without further development. Their descendants were different from those of Swiss watchmakers, and they had almost no idea of ​​doing such simulations. What is seen is the gradual demise of an industry.

A master skilled in the frequency calibration of analog sensors recently did not do any work either. It indirectly predicted that the rapid extinction industry would encounter some difficulties again. The new investors will not focus on this as their focus of development, but instead they will try their best to manage foreign countries. Instruments, agents and money come quickly, which directly led to the fading of the ultra-low frequency measurement sensor industry from the Chinese market. Think of the vibrating screen as above when the spaceship was launched into the sky. Think about the damage of some large buildings at low frequencies. Think about the collapse of the US highway bridge... What methods are there in addition to these electromagnetic electromagnetic sensors in ultra-low frequency measurements? MEMS has not yet been replaced in this industry, and it is impossible to test this environment for at least a few years. It should be clear to see that the challenges faced by the traditional analog vibration measurement industry are on the one hand due to the renewal of technology and more from the short-sighted understanding of analog sensor design.

When Nevada Benteley was acquired by GE, Shenke Company attacked the Chinese market in a big way, and the Japanese Production Institute desperately played this professional analog sensor... When we Chinese chose other things to do. Maybe profit is the most important, so we have to go for more embedded systems, so fast, we can use money to buy products, and we have to admit that many times we can't buy technology, even if broken. Solution can not be broken for a while. To solve the next move of people, the result is always backward, no wonder foreigners often say: has been copied, but it has not been exceeded.

Similar industries such as domestic mass spectrometry instruments, many hospital-use detection instruments, and familiar battery resistance test instruments are almost all cheap, low-end products, and few can be made decent. In recent days, nothing foreign has opened up some foreign instruments. One of the reasons why we are lagging behind is that it is very simple, because we do not correctly understand the position of analog designs in the instrumentation system. In addition, we are not good at using simulation to cause us not to Dare to use simulation, and then let the cost requirements make us even less dare to approach simulation. As time passes, we cannot find several dare to use more than ten operational amplifiers in our instrument system. Instead, we use digitized algorithms, and the indicators are not. Go, the function is there.

In fact, at this time we should wake up to where our short board is. The trend of the industry is the digital world. The prototype of the instrument can also return to the harmony of analog design and digital design. Otherwise, many noise and speed indicators cannot be harmonious. Do not believe that you only take the DSP to make the alias noise completely harmonious. To be kind to the analog design, it is not the question of who is the second room, is it the problem of the original system when it is embedded in the system, but it is the problem of re-understanding the simulation.
