With the further development of artificial intelligence (AI), Internet of things (IoT), big data and other technologies, intelligent equipment industry has become the cornerstone of industrial structure upgrading.According to the 《12th five-year development plan of intelligent manufacturing equipment industry》 released by the state council, China will establish a complete intelligent manufacturing equipment industry system by 2020, with the industrial sales revenue exceeding 3 trillion yuan, and realize the intelligent equipment and automation of manufacturing process.
Intelligent equipment refers to manufacturing equipment with functions of perception, analysis, reasoning, decision making and control, which is the basis of intelligent manufacturing. At present, the focus of industrial intelligence is to use intelligent process equipment to build a more efficient and energy-saving process industry, and to put forward customized system schemes for different fields.

Sensor is the key hardware entrance of intelligent equipment, is the automatic input device of equipment, is equivalent to the sense organ of intelligent equipment. In the process of intelligent equipment implementation, sensors with high reliability, stability and security are essential. From the perspective of industrial production, most factories include machine processing, assembly, inspection and logistics, and vibration sensors play an important role in each process.
We are now in the era of the big data explosion, and so is industry. In the industrial Internet of things (IIoT), more and more data needs to be processed timely and effectively at the edge, thus reducing the burden on cloud computing centers or local servers. Therefore, intelligent sensor comes into being. Sensor manufacturers integrate sensor unit and microprocessor into a single chip through MEMS process. Intelligent sensors transform complex signals from centralized processing to decentralized processing, which can ensure the quality of data processing, improve anti-interference performance and reduce the cost of the system. Intelligent sensor makes the sensor develop from single function and single detection to multi-function and multi-variable detection, and makes the sensor change from passive signal detection to active control and active signal processing.
Of course, intelligent upgrading of sensors includes not only the fusion of sensors and other components such as microprocessor and memory, but also the fusion of sensors with different functions, enabling sensors to do more things in a limited space. Demand for multi-sensor fusion systems is expected to grow at a compound annual rate of about 19.4 per cent over the next five years to reach a market size of $7.58bn by 2023, according to data released by McCombs consulting. Therefore, with the increasing importance of intelligence in industrial production, the vibration sensor itself is also rapidly upgraded and iterated.
The rapid growth of intelligent equipment allows sensor manufacturers to embrace a new development opportunity. At the same time, sensor manufacturers also have to face challenges with opportunities. At present, the transformation of industrial manufacturing is mainly reflected in three aspects, including the transformation from mass production to customization, the transformation from a single product to multiple varieties, and the short renewal cycle. Moreover, in the process industry, continuous production is the main method. Once the fault occurs in the detection and control, the whole production will come to a standstill, and even the occurrence of safety accidents. This requires the manufacturing equipment to have a high degree of autonomous mode, self-repair system, self-configuration system and other higher-level functions on the basis of the realization of networking and intelligent, which puts forward high requirements for the product development and design of sensor manufacturers.
Also, safety is a topic that cannot be overemphasized. The safety of industrial field is the key problem of industrial control system, especially to ensure the safe and reliable operation of the control system. Vibration sensor is the main source of data loading, and it also plays a leading role in the field of industrial data security.
