1 Introduction
On November 8, 2012, Shanghai Renwei Electronic Technology Co., Ltd. successfully applied the “Semi-active RFID technology in automotive production line process management system” in Hunan Shaoyang Sany Heavy Industry’s automotive production line management. The system realizes the intelligent statistics of the assembly line of the large-scale automobile production line, the monitoring of the production process from time to time, and the automatic statistics of the time-consuming of each station. It replaces the traditional manual statistics method, and realizes the information words of large-scale production enterprises to the greatest extent. . It is also a pioneer in the innovative application of Internet of Things technology in large-scale manufacturing industries.

In the system, the vehicles to be produced are equipped with semi-active electronic tags, and a set of low-frequency activator antennas are installed at different positions on the production line (position judgment, Ren Microelectronics unique positioning mechanism). At the same time, 2.4G industrial installations are installed in the relevant positions of the entire workshop. Class omnidirectional reader is used to receive signals from semi-active tags. 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.
