In the 21st century, network informationization and computer intelligence have made great progress in the field of industrial technology.
In modern machinery factories, from the input of materials, loading and positioning, machine start and stop, parameter adjustment, cutting, workpiece disassembly, to transportation, all digital, fully automated, unattended; A regular car can be equipped with dozens of microcomputer control units, such as engine ECU, transmission TCU, and Anti-lock lock (ABS, etc.), brake power distribution (EBD/CBC, etc.), brake assist (EBA/BAS/BA, etc.), traction control (ASR/TCS/TRC, etc.), body stability control ( ESP/DSC/VSC Etc.), cruise control, automatic air conditioning systems, data bus communication control, route navigation, remote location communication service systems, and car audio and video systems, etc, The core of these components is a computer microcontroller. The computer microcontroller senses the external dynamic information through the sensor and accepts the driver's operation instructions. It performs intelligent analysis and judgment through the internal core control strategy, and outputs control commands to accurately and timely control the actuators to respond. To achieve the desired control objectives.
The research work of intelligent engineering machinery technology in China began in the early 1990s. In 1991, the state launched the "863 Program". Under the advocacy of Jiang Xinsong, the chief scientist in the field of automation, the company first carried out research work on the engineering robotization technology in the country, and successively carried out the robotization of excavators and the robotization of bulldozers. (AGV) technology development. Some institutions of higher learning and scientific research institutions, such as the Chinese Academy of Sciences, Tsinghua University, Jilin University and Tianjin Engineering Machinery Research Institute, have conducted joint research and development with a number of domestic construction machinery manufacturers.
Nowadays, China's construction machinery industry has entered a high-speed development channel, and key components such as transmissions, high-pressure hydraulic parts and electronic controllers are too dependent on imports. This limitation factor affects the strategic expansion of China's complete machine manufacturers and solves the problems of key components. It has reached an urgent point, so the “Twelfth Five-Year Plan” period is a good time to invest in the key parts and components of construction machinery.
