Description

Intelligent tool cabinet based on RFID technology and intelligent tool management system

Technical Field

The utility model relates to an intelligent tool cabinet based on RFID technique relates to the intelligent tool management system including intelligent tool cabinet simultaneously.

Background

The railway field has strict requirements for the management of service tools. In the guidance opinions of signal operation of high speed railway, after the tools are checked and matched before and after the vehicle enters the railway, the vehicle can continue to be marked, delivered and used. The management of the tool is an important node in the construction of a railway safe operation and intelligent operation and maintenance management system.

At present, the railway industry generally adopts a manual checking method or a handheld RFID terminal scanning method to manage tools. Due to the fact that the types and the number of the used tools are large, the overhauling operation is performed at night, the visual field is poor, and the low-efficiency management method is always a disadvantage in railway tool management in limited skylight time. The management mode of manual counting or handheld RFID terminal scanning is difficult to realize timely and efficient management and control of tools, and the requirement of high-speed development of a railway system is difficult to adapt.

With the development of scientific technology, many intelligent tool counting methods have appeared in recent years, such as fixed tool cabinets (door type channels) and portable tool boxes based on the RFID technology; tool homing detection based on gravity or proximity sensors, and the like. However, as described below, the above-described tool inventory methods also have problems to a greater or lesser extent.

To the fixed tool cabinet (gate-type passageway) that adopts the RFID technique, what adopt mostly is one-way or correlation formula antenna overall arrangement, and this kind of mode also can realize discerning the instrument that posts the RFID label, but when the instrument is more and be the metal material, can appear the problem the same with handheld terminal, and the miss-detection rate is higher, needs to detect many times or turn the instrument usually and just can reliably discern.

In addition, some patent documents refer to the design of drawer type tool cabinets, and each drawer partition is provided with an RFID radio frequency antenna, so that the method needs more antennas, is higher in cost and complex in system, and different drawers need to be opened when tools with different sizes are taken and placed, so that the tool storage is not convenient in actual use, and the size of the tool storage is limited.

Although the portable tool box adopting the RFID technology can realize automatic checking of an operation site and the input and output of tools, the portable tool box is a portable device, so that the management of the device is difficult, and in order to meet the requirements of a site use environment, the box body is usually heavy, and the burden is increased for maintenance personnel to a certain extent. Meanwhile, in order to take account of portability and light weight, the size of the maintenance tool cannot be large, so that large-size maintenance tools used by railway engineering professionals cannot be put into a box, and the application range is greatly limited.

For the methods of tool homing detection based on gravity or proximity sensors and the like, the tool needs to be placed at a specific position and cannot be randomly taken and placed, so that the operation is inconvenient. Meanwhile, a sensor needs to be installed at each position where a tool is placed, the cost is high, and the system wiring is complex.
