1 Introduction
On November 8, 2012, Shanghai Renwei “based on semi-activeRFID“Technology in the process management system of automobile production line” was successfully applied in the management of automobile production line of Hunan Shaoyang Sany Heavy Industry. This system realizes the intelligent statistics of the production line of large-scale automobile production lines, the monitoring of the processes in the production process, and the automatic statistics of the time consumption of each station, etc. It replaces the traditional manual statistical method, realizes the intelligence of large-scale production enterprises to the greatest extent. It also pioneers the innovative application of Internet of Things technology in the large-scale manufacturing industry.

In the system, the vehicles to be produced are equipped with semi-active electronic tags, and a set of low-frequency activators are installed at different stations on the production lineantenna(Location determination, Ren Microelectronics has a unique positioning mechanism). At the same time, 2.4G industrial-grade omnidirectional readers are installed and deployed to receive signals from semi-active tags in relevant locations throughout the workshop. When the vehicle to be processed enters different stations of the production line, the information monitoring center always displays which process it is in, how many processes can be completed, how long each process takes, and how long each station takes, etc.
The system records the production status of each station and the output of each production line in real time. According to the number of products to be produced and the flow schedule, the management personnel can easily optimize production efficiency and improve production quality. With the help of advanced technology, the realization of intelligent, automated, and informatized automobile production has made a qualitative leap in the overall production and management level, and has also greatly improved the image of Sany in the field of heavy industry, bringing positive results from many aspects. Influence.
