As a new generation of IoT technology, high-precision positioning technology is listed as a key industry in the digital economy of the 14th Five-Year Plan. This has played a good role in promoting the digital upgrade of the automobile manufacturing industry.

The automotive industry is a leader in smart manufacturing. In recent years, the rapid development of the domestic auto industry, especially new energy and smart vehicle technologies, is inseparable from the strong support of various new technology innovations. Through the transformation and upgrading of digital technology, the production efficiency and management efficiency of automobile manufacturing can be greatly improved. Woxu Communication's high-precision positioning service has been committed to helping industrial enterprises carry out digital transformation. This article will discuss the digital transformation road of the automobile manufacturing industry through the practical application cases of the domestic high-precision UWB module UWB technology in the automobile manufacturing industry.

Automobile manufacturing is a typical discrete manufacturing production, and the entire manufacturing process is very complex, from model development and design to stamping, welding, painting, assembly, post-product storage and other steps, is a very complex and huge industrial production. Among them, the complex production and assembly process of the assembly workshop, the large number of operators, the large amount of information, the concentration of external components, and the difficulty in quality control management are the key points for the factory to implement intelligent manufacturing.

Based on the above background, digital transformation has become a new breakthrough point for the innovation of traditional auto companies. Through the deep integration of a new generation of information technology and manufacturing technology, the intelligent, automated and efficient lean management of the workshop has been realized. At this stage, the digital transformation of auto companies has also achieved some phased results, but the following problems are also faced during the entire promotion process:

1. The actual duration of each process of vehicle assembly production is difficult to be accurately counted and analyzed in real time;

2. It is difficult to count the number of vehicles in production and their status in real time;

3. The number of vehicles is large, and the mobile parking is irregular, which makes it difficult to find a vehicle;

4. It is difficult to judge whether the vehicle is performed according to the standard test through the route data;

5. There is a lack of correlation between the vehicle road test and personnel information, and it is difficult to track the vehicle road test problem;

Faced with these practical problems, the domestic high-precision UWB module UWB high-precision positioning system was introduced on the basis of the existing intelligent construction of the workshop, and the original intelligent system was upgraded and put into practice to realize the information interconnection of the assembly workshop, the optimization of the production process, and the traceability of vehicle detection problems. etc., make the workshop more intelligent and transparent.

Taking a large automobile factory as an example, a certain number of base stations are deployed in the assembly workshop, and the car tag and vehicle VIN code are scanned through PDA to realize the binding of UWB tag and vehicle; the calculated position information is sent to the positioning tag through UWB communication of the positioning tag. After the base station is installed, the location information is sent to the upper computer software system through the communication module on the positioning base station, and is connected with MES/WMS/ERP to realize intelligent monitoring of workshop production.

1. Location data tracking

With UWB technology as the core, it fully integrates vehicle location data, vehicle production time, vehicle detection trajectory and other data information, can quickly find vehicle information of vehicle information, track its movement trajectory, and realize the whole process from assembly line, static detection line to final delivery and marketing. Process refinement management, making workshop management visible and tracking results.

2. Optimize production line efficiency

In the production promotion process, the vehicle needs to complete the vehicle assembly through the production line process. We can monitor vehicle entry time, dwell time, departure time and track opening time and trajectory line, efficient, accurate, unattended statistics, as well as online/offline production progress and takt realization, for factory MES The system provides data support to improve the optimization of the production process.

3. Process early warning analysis

After the vehicle is assembled, it will enter the inspection stages of precision inspection, dynamic inspection, road inspection, spraying, and maintenance. In order to ensure that the vehicles are in the normal detection sequence, we set up electronic fences on the key detection routes. According to the detection process preset by the system and the current detection progress of the vehicle, it is judged whether the vehicle should enter and whether it is carried out according to the normal procedure. warning.

In addition, we can also set the overtime stop, analyze the stop time of each vehicle in each process, and realize automatic alarm by the stop vehicle icon turning red/flashing, thereby improving the early warning processing capability.

In the whole project, the high-precision positioning system is used to connect with the production and manufacturing systems of large automobile enterprises to create a more efficient, accurate, lean and transparent intelligent production management system. It will take advantage of the Dongfeng of the 14th Five-Year Plan to serve more automobile manufacturing enterprises and help enterprises with digital transformation.
