The first strange sensor has a large capacity, while the domestic head players are very small. In 2019, China's sensor market reached 220 billion yuan, with an estimated more than 1700 enterprises, but only a few with an output value of more than 100 million, such as Nanjing Novell, Baoji Maite, Nanjing Gaohua, etc. With the strong shipments of Apple mobile phones, Goethe and Ruisheng have occupied the territory in the field of acoustic sensors. However, other fields, such as mobile phones, automobiles, industrial control, wearable, Internet of things, etc., are basically the markets of foreign brands. Domestic enterprises are basically potato clubs.
Sensors are the second strange, with a wide variety, but this market is very hidden. There are nearly 50000 kinds of foreign molding products and types under research, and there are more than 6000 kinds in China. But the sensor market is little known. In fact, small sensors are indispensable for the implementation of intelligent manufacturing, industrial Internet and artificial intelligence in recent years. Mobile phones and cars are also big users of sensors. In these aspects, Bosch, Renesas and Infineon take the initiative.
The third strange sensor is that civil products are afraid of supply interruption, and military industries are afraid of supply interruption. Military industry is not worried, because military sensors have been highly autonomous, mainly because their procurement cost can be ignored. If we compete in the civil market, we should not only fight for scale, but also have cost performance. If the power consumption is lower and the cost is lower, the winner takes all. Therefore, the breakthrough in the civilian market is still very difficult, and it is impossible to obtain support from the military market. The two tunnels, each on one side, did not get through. The method of pinching neck in foreign countries is also very hidden. Yokogawa, Japan and Chongqing Chuanyi have a joint venture to produce Yokogawa instruments. The resonant pressure sensor provided by Yokogawa, Japan, is the highest precision pressure sensor. Domestic key problems have not been solved. Yokogawa instrument is in a state of "Notification price increase and reward supply". If Yokogawa in Japan only provides 10000 chips and sensors, Yokogawa instrument can only do 10000 sets of equipment.
Fourth, the cost advantage of China is not as obvious as that of foreign countries. At present, most of the sensors produced in China are low-end sensors. The import of medium and high-end sensors accounts for 80%, and the import of sensor chips accounts for 90%. China's production cost is also very high, and the income is only tens of millions. How can we be willing to invest tens of millions of production lines? Now many sensor manufacturers still work alone and assemble a lot by hand. Because the quantity can't go up, there are only 5000 in a month. There is no economies of scale. Bosch and OMRON have long set up factories in China, and the cost advantage is also huge.
Virtue day is eyeing China's sensor market and is very close to market share. As soon as China makes progress, it will be squeezed by the price reduction of foreign brands. In 2010, a photoelectric proximity switch of OMRON in Japan cost 400 yuan, but now with the gradual rise of Chinese brands, it only costs 60 yuan. Flexible price reduction and firm defense of market share are common marketing means for foreign manufacturers. In this way, domestic brands have been suppressed near the sallow line, which is difficult to turn over.
Sensor fifth strange, the market is huge, financing is the most difficult. Originally, intelligent manufacturing and artificial intelligence were very hot, and the sensor should finally welcome the salted fish. However, wood has. This market is an enterprise that investors don't want to see. The same is true abroad. Shike photoelectric sensor in the field of industrial control is the only sensor company listed in Germany. Many family businesses are millions or tens of millions of euros for a long time. Domestic investment has been in a cold period due to lack of understanding.
The sixth strange sensor is noble in quality. How can it land as a grass-roots citizen. Sensors are the first line of defense of perception and the source of intelligence. However, this industry has not been paid attention to. In the early 1980s, what technologies did information technology include in the research project presided over by the State Science and Technology Commission? "Sensor technology" has caused great differences. But in the end, because the volume was too small, the sensor was cut off. In a flash, forty years have passed, and the situation has hardly changed. Not even a decent sensor policy.
Sensors are the five senses of all things, eyes, ears and all kinds of touch. So important, but no one pays attention to it. The six strange sensors are a strange thing in themselves. This is a heart piercing thorn # to save the sensor#
