1、 Development and understanding of intelligent manufacturing

1. Intelligent requirements

(1) Intelligence is the development direction of scientific and technological innovation

Nowadays, more and more information is readily available, but why do we feel more confused and ignorant? This is a problem of information retrieval and knowledge discovery. The profound implication behind it is that informatization is the foundation and intellectualization is the advanced stage of informatization development.

The 21st century is the era of biotechnology. With the gradual deepening of life science research, such as gene, brain, and cognition, intelligent science is gradually unveiling the mysterious veil and becoming the driving force of basic science in the 21st century.

In the field of modern manufacturing and information technology, intelligent technologies such as language recognition and understanding, image recognition and processing, computer vision, robot planning, multi information sensing and control, knowledge expression acquisition and processing, reasoning and decision-making, expert systems, intelligent optimal control, etc. are increasingly widely used.

For example, the advanced Google driverless car can achieve the maximum speed limit of 60km/h under the automatic driving mode. The stop sign provides voice prompts, the main control system provides fault detection alarms, manual operation prompts in unfamiliar environments, and road condition adaption at intersections. The core of the system is the laser rangefinder on the roof. When the device rotates at a high speed, it emits 64 laser beams around, and the laser hits the surrounding objects and returns, The distance between the car body and the surrounding objects can be calculated. The computer system will draw a fine 3D topographic map based on the distance data, and combine it with the high-resolution map to generate different data models for the on-board computer system.

The recently popular 3D printing manufacturing technology can rapidly "print" product prototypes or parts based on the principle of layered stacking of discrete materials and 3D CAD models of products. It is a systematic and comprehensive technology integrating multidisciplinary knowledge such as computer software, materials, machinery, control, network information, etc. Its principle is based on 3D models, through software layered discrete and CNC molding systems, using laser beam By means of hot melt nozzle, metal/ceramic powder, plastic, cell and other materials are stacked and bonded layer by layer to form a solid product.

Another example is an intelligent engine that relies on the fusion of sensor data and expert models to fully understand the state of the environment and the engine, realize self adaptation, self diagnosis and self prediction, make active self-management decisions on the performance and state of the engine, and take physical actions to execute. These are the embodiment of intelligence in scientific and technological innovation.

(2) Intelligence is the inevitable trend of customer demand and social development

The direction of improving people's quality of life is changing from material to spiritual. The demand for products is becoming more and more digital, miniaturized, personalized, easy to operate, safe, healthy, caring and humanized. Only intelligent products and facilities can be highly flexible and adaptable.

The development and application of modern information technology has gone deep into various sectors of the national economy and various fields of social life, greatly promoting the development and reform of social production relations. It is an inevitable requirement for social development to apply intelligent technology to commercial trade, culture and education, transportation, national defense, administrative management and other departments, and build smart homes, smart communities, smart grids, smart transportation, smart cities.

(3) Intelligence is an inevitable requirement for the development of manufacturing industry

Today, the survival and development environment of the manufacturing industry is facing a series of problems, such as difficult to support resources, increased environmental pressure, increased user demand, flat trade friction, fierce market competition, increased labor costs, and increased operating expenses. It is necessary to develop from the traditional manufacturing mode to the direction of intelligent production services, green environmental protection, innovative intelligent design, high-end equipment manufacturing, automatic equipment, intelligent fine management, etc.

2. Background and significance

From this, three driving forces to realize intellectualization are summarized, namely, the development direction of scientific and technological innovation, customer demand and social development trend, and the development requirements of manufacturing industry. The specific connotation of intelligence includes intelligent equipment, intelligent products, intelligent design, intelligent production, intelligent service and intelligent logistics. These are clearly corresponding to the micro curve. The method to realize the corresponding process of intelligent products is called intelligent design. The other end is the after-sales service of the future market, including intelligent equipment and services. Intelligent manufacturing realizes intelligent production. Intelligent logistics can effectively improve the quality of products and reduce the production cost of products. Intelligent manufacturing is the key to the deep integration and development of "two modernizations" of manufacturing industry and the realization of transformation and upgrading of high-end manufacturing.
