Background

Due to the fact that the maintenance tools and instruments are various in variety, large in quantity and different in specification, the tools and instruments are messy and not classified, and when a worker wants to use a certain tool, the worker is particularly troublesome to find. When the tool is lost, no effective means is available for searching, and the tool can only be searched slowly by spending a large amount of manpower and time, thereby increasing the working difficulty. The tool and instrument maintenance management system mainly based on manual operation needs a large amount of personnel operation, and has a long management flow and hysteresis. When a tool is lost or damaged, it may be discovered a few days later or even the next time it is desired to use the tool. When borrowing the ring segment, because the borrowing procedure is more complicated, when recording the borrowing condition and receiving and dispatching by tools, the phenomenon of waiting in line often appears, wastes the time of maintenance personal.
