The use of radio frequency identification technology (RFID) to design a train station tools safety management system, to achieve the train station tools in a certain space area of the batch borrowing and returning, batch counting. At the same time, the use of readers and routers arranged in various places in the train station to achieve regional positioning, safety interlocking function.
Realise the function of regional positioning and safety interlocking.

The demand for rolling stock is increasing, and there are many types of rolling stock models, and the tools needed for their maintenance operations are also becoming more and more complicated. In order to realise the requirement of zero-failure out of the depot, a ground mechanic usually needs a set of toolkit (16-piece set), walkie-talkie, camera flashlight and other special tools for one overhaul operation of a rolling stock. In the dynamic car tool room, the use of two-dimensional bar code and manual registration of borrowing and returning tools, bar code can only be scanned individually, tools and the existence of centralised borrowing and returning, often queuing phenomenon. Coupled with the bar code is very easy to deface and fall off, maintenance process is often accompanied by dust and oil, return the bar code is often already worn or lost, you need to query the system to return the borrower's name in order to return, inefficient.

It is inefficient to build a set of RFID-based tool safety management system to ensure the safety of the fleet and optimise the workflow. Moreover, in the process of maintenance, if the tools are lost in the train set, especially in the skirt and roof, it will cause great safety hazards and seriously threaten the safe operation of the train set.

The use of RFID ultra-high frequency (UHF) electronic tags and intelligent transport system combined, through the antenna transmit radio frequency signals, RFID tags to receive signals, RFID readers to complete the decoding of the signal work, passed to the processor for back-end processing.

Through the use of ultra-high frequency tags and read-write, can be completed in the longest distance 10m range, poor conditions, without the need to achieve multi-label recognition in the visible range, to achieve convenient management, fast response, realize the tools batch borrowing and returning, at the same time on the torque calibration information entered into the label. Positioning of tools and safety interlocking functions to ensure the safety of the maintenance of rolling stock and the safety of the property of the rolling stock operation.

In view of the daily maintenance operation of the railway station on the management needs of the tools used, a new method is proposed. For the management demand of tools used in the daily maintenance operation of the railway station, a RFID-based tool safety management system is proposed to realise the safety of tools used in the railway station. A RFID-based tool safety management system is proposed to realise the digital and intelligent control of tool management in a rolling stock depot, improve the efficiency of tool management, and ensure the safety of rolling stock maintenance and property safety. It can achieve digital and intelligent control of tools management, improve the efficiency of tools management, and guarantee the safety of the operation of the train sets and the safety of the property of the railway station. The system can also be extended to aviation inspection. The system can also be extended to aviation maintenance, electric power maintenance and other complex scenarios. The system can also be extended to aviation maintenance, electric power maintenance and other complex scenarios, and has a wide range of application prospects.
