Shuttle back and forth AGV car, orderly transport parts, encounter pedestrians automatically stop. On the production line, the robot can flexibly carry out a series of operations such as stamping and welding As an old industrial base, automobile industry has been an important pillar industry of Chongqing industry for a long time. At present, there are 21 complete vehicle enterprises and more than 1000 spare parts enterprises in Chongqing, and more than 70% parts and components have been locally matched. The intelligent road of Changan Automobile is an epitome of the transformation and upgrading of the automobile industry to high-end, green and intelligent, and to realize the transformation from a big automobile city to a strong automobile city. < / P > < p > automatic parking, human vehicle interaction and driverless driving have become a reality in Chang’an, Chongqing, Western China. Chang’an uni-t, as the first model of Changan Automobile’s new series “gravity”, is the representative of intelligent vehicle in the new era. Wu Weigang, manager of Changan Automobile management innovation and it center, said that the manufacturing base behind the intelligent Changan uni-t is also “very intelligent”. < / P > < p > the reporter learned on the spot that there are 535 industrial robots in the welding workshop, which can realize the functions of automatic welding, automatic gluing, automatic handling and automatic detection. The spot welding automation rate is as high as 97%, which is far higher than 80% of the industry level. < / P > < p > the stamping workshop has two 2400t double arm full-automatic high-speed closed stamping production lines times / min, with low noise and environmental protection. At the same time, it adopts key technologies such as synchronous control, CNC hydraulic pad and automatic die change, representing the most advanced large-scale complete set of stamping equipment production level in the world. Huang Zhonglu, welding worker of Liangjiang factory of Changan Automobile, told the reporter that the crane spreader installed on the crane of the production line in Chang’an Automobile Workshop is designed and made by the workshop staff, thus reducing the hours of stamping production line, not only improving the efficiency of die change, but also reducing the labor intensity of workers, and improving the level of intelligence. At present, the company has put forward the “smart car manufacturing plan” from the traditional automobile manufacturing company. < / P > < p > the production efficiency is increased by 25.4%, the defective rate of products is reduced by 50%, the R & D cycle is shortened by 33.3%, and the operating cost is reduced by 22.1% Recently, after the implementation of intelligent transformation for Chongqing Jicheng automotive electronics company, the company’s production and operation indicators have changed greatly. < / P > < p > the key to this is from a small “industrial ID card” and the technology behind it – identification analysis. Any assembly and processing equipment in the factory has a small two-dimensional code. Through the scanning equipment all over the factory, you can find everything about the owner of the “ID card”. < / P > < p > “this greatly improves the informatization level of production.” Ye Xingliang, the project leader of Jicheng automobile electronic manufacturing center, said that now, if the production line workers scan the two-dimensional code identification, the system will clearly know what kind of processing parameters should be matched, and quickly and automatically match the parameters to the equipment for production, thus realizing product identification and equipment processing customization. < / P > < p > the traditional motorcycle enterprise Zongshen power MOFA 1011 line is also one of the mature cases of khumi to transform the production line with the core technical capabilities of identification analysis and cloud MES. At present, the error correction efficiency of shenfa line has been increased by 1016%, and the per capita power of automatic production line has been increased by 10.4 times. According to the reporter from Chongqing Economic and Information Commission, there are more than 15000 digital economy enterprises in Chongqing. In 2019, the added value of Chongqing’s digital economy will increase by 15.9%; in the first quarter of 2020, the city’s digital economy will grow against the trend, realizing an added value of 115.73 billion yuan, accounting for 23.2% of the total GDP of Chongqing. < / P > < p > in order to accelerate the transformation of traditional industries to digital economy industries, Chongqing proposes that by 2022, Chongqing will focus on “core screen device core network” to help the construction of six digital industry clusters and eight digital industry bases in Chongqing, and achieve remarkable results. < p > < p > Chongqing industrial big data innovation center, established by China Aerospace Science and industry group, is one of the first two manufacturing innovation centers in the city, and is still applying for a national industrial big data manufacturing innovation center. Since its official settlement more than a year ago, the center has completed more than 1300 enterprises “going to the cloud” in Chongqing, linking thousands of sets of industrial equipment. < p > < p > guanghuai group, a leading enterprise in the field of power equipment manufacturing, has learned that with the help of Chongqing industrial big data innovation center, through the establishment of an industrial Internet platform, the enterprise has comprehensively improved the management and control ability of equipment, products, resources and data, improved production and manufacturing efficiency, reduced operating costs, and is gradually transforming into an intelligent industrial enterprise. < / P > < p > “relying on the National Engineering Laboratory of industrial big data, we, together with Chang’an Automobile and Chongqing University, jointly undertake the project of” research and demonstration of network collaborative manufacturing integration technology for automobile industry agglomeration area “in the special project of” network collaborative manufacturing and intelligent factory “of the key research and development plan of the Ministry of science and technology in 2019, and jointly build the industrial Internet platform of the automobile industry.” According to the relevant person in charge of Chongqing industrial big data innovation center, the project will focus on the whole Chongqing Automobile agglomeration area, develop a “point line plane” integrated service platform for leading automobile enterprises, intelligent factories and regional agglomeration, and link more than 1000 enterprise users across industries, so as to enhance the regional industrial agglomeration effect and promote the transformation and upgrading of Chongqing automobile manufacturing industry. Tencent Western cloud computing data center has provided cloud services for more than 100 well-known enterprises at home and abroad since it was put into operation. Hu Xujun, general manager of Tencent Chongqing Branch, said that the data center is committed to developing high-performance computing capabilities and cloud technology capabilities to provide power for the intelligent transformation of traditional industrial manufacturing industry.
