Development Status and Problems of Intelligent Manufacturing Technology in China

Equipment manufacturing industry is a basic industry that provides technical equipment for national economic development and national defense construction. The development level of equipment manufacturing industry reflects the comprehensive strength of the country to a certain extent, and its development also provides an important guarantee for China's industrial upgrading and technological progress. At present, China's equipment manufacturing industry has made remarkable achievements. Thanks to the strong support of national industrial policy and the transformation of global industrial structure, most equipment manufacturing enterprises have been promoted in industrial added value and profit growth.

After years of development, China has accumulated rich practical experience in product research and development, production and management of construction machinery and rail transit equipment, and the leading enterprises represented by Sany Heavy Industry, CRRC and China Railway Industry have gained international competitiveness. At the same time, based on the continuous accumulation of technology and international market operation experience in the past decade, China equipment enterprises have already possessed the strength of "going out" in core competitive factors such as brand, technology and products.

Leading enterprises focusing on railway construction, operation and vehicle equipment manufacturing have made great achievements, completed technology accumulation and started to go out. In some important equipment manufacturing fields, with the application of new technologies such as Internet of Things, 5G and AI, the intelligent empowerment of digital technology to equipment manufacturing industry has become the norm.

Digital Twinning helps traditional enterprises to create online 3D monitoring scenes, and realize the comprehensive presentation and accurate operation of 3D models through human-computer interaction functions such as attitude control, real-time data monitoring and display, remote control of equipment and system roaming. It enables enterprises to produce and manage more efficiently and intelligently, and provides important technical support for realizing sustainable development.

The three-dimensional visualization of locomotive maintenance station in railway construction shows the application of digital twin technology in locomotive maintenance station, from the overall scheduling of maintenance station to the operation flow of each section, to the maintenance of each locomotive and the work of workers. Combining the actual physical system with its digital model, driven by field data, the key data in the operation process are obtained in real time, and the simulation and monitoring of the whole operation process of the sand loading and sewage unloading shed are realized. Thereby improving work efficiency and safety, and providing scientific decision support for managers.

Through the digital twin model, managers can simulate the operation process, evaluate the effects of different schemes and optimize them. This is helpful to improve the management level of maintenance yard, optimize resource scheduling and improve maintenance efficiency.

The automobile assembly workshop carries out real-time monitoring, trend analysis, judgment and early warning and quality traceability on the production process through specific algorithms and analysis software, so as to ensure that the staff can grasp the running state in real time, or check the installation process and location of the exhaust system through historical records. Point out the direction for later quality improvement and form closed-loop management of manufacturing data.

It not only embodies the excellent manufacturing technology of the current automobile production line, but also shows the high level of integration of Hightopo 3D visualization technology and reality. It can also remotely monitor the assembly work of digital twin equipment and realize all-weather, three-dimensional and multi-directional personnel management mode.

The operation of mechanical equipment carries out 2D visual design on the main process flow of the factory assembly line, and carries out classified design according to different units, such as automatic welding line for legs, automatic adding line for small parts, automatic production line, automatic heat treatment line for straight pipes, automatic welding line for straight pipes and automatic coating line for special steam mixing barrels, and visually presents the process flow by combining the real-time data monitored after accessing the measuring points.

In the visual interface, each welding robot has its corresponding alarm device, and its status is summarized in real time according to the alarm level, which is displayed on the right panel in turn. According to the data information transmitted by the sensor carried by the welding robot, the equipment efficiency index is displayed intuitively in the form of graphics.

When the mouse passes the welding robot equipment, it will be highlighted. Click to enter the device interface, which is a two-dimensional display of the device. Both parties shall supplement the basic information of relevant equipment, including welding current, welding voltage, wire feeding speed, equipment efficiency index, etc., so as to facilitate users to master the details of the equipment.

The display effect of 3D animation technology realizes the content in real production from the perspective of science fiction and the future.

Through data model+basic UI library +2D topology +3D rendering engine, the production line flow of digital duplex mechanical equipment manufacturing industry aims to contribute to the construction of "digital duplex+industrial Internet" and truly realize intelligent manufacturing and digital surveying and mapping system beyond reality.
