As an important component of smart factory data flow, high-precision location data is one of the three data indicators of time, space and state in smart factory business flow. The accuracy, real-time performance and coverage integrity of spatial location data are important evaluation dimensions of the perceived quality of smart factory front-end. To build a high-precision positioning management system based on indoor positioning technology, starting from the difficulties and pain points of management of different types of manufacturing enterprises, indoor positioning technology can be used to achieve accurate positioning, seamless tracking, intelligent deployment and efficient collaboration of people, vehicles, materials, etc., in the factory, to greatly improve the lean production and fine management level of the factory. At present, intelligent manufacturing applications such as aerospace, automotive manufacturing and assembly, electronics manufacturing, and home appliance manufacturing are actively introducing in-room positioning technology to achieve efficient management within the plant. The important role of positioning technology in intelligent manufacturing is mainly reflected in three aspects:

Efficient personnel management, based on the real-time positioning data of personnel, personnel attendance, time statistics, arrival/departure and other work status management.

Materials and materials positioning tracking, production process tracing, through the use of indoor positioning technology, to achieve the production of each product flow process (including order receipt, product ID confirmation, production assembly, testing, in-plant storage, outside the plant logistics and other links) traceability and highly transparent process, standardize the work process, while greatly improving the efficiency of the work.

Adaptive tool search and error prevention, by installing unique ID location tags on the device tool, and according to the execution information pushed by the mobile terminal, quickly obtain the tool according to the real-time displayed tool location, so as to achieve the right time, the right place, for specific components, obtain the right tool, execute the correct operation procedure, etc. Increase productivity and prevent tool mismatches from affecting product quality.

In the field of intelligent manufacturing, location information is mainly used to improve production efficiency and supply chain management, and to prevent errors of tools to improve product quality. Intelligent manufacturing has high requirements for positioning accuracy, requiring 10~30cm positioning accuracy, and its operation scenario also has high requirements for anti-interference and anti-occlusion ability of positioning technology, and the positioning terminal is mainly for equipment and enterprise employees, the terminal can be customized, but the power consumption is as low as possible.
