Description

Technical Field

[0001] The present invention relates to the field of tool boxes, and more specifically, to a portable intelligent tool box based on RFID technology. Background Art

[0002] Railway inspection and maintenance workload is heavy, a large number of tools are used, and the working environment is complex. Inspection and maintenance tools are carried by maintenance personnel, and it is inconvenient and difficult to collect, return, find, and maintain portable tools. Therefore, safe and efficient management and use of tools is very important for railway locomotive crews.

[0003] The traditional management method is manual counting and confirmation. Due to the large number of tools used, and the fact that maintenance work is usually done at night with a narrow field of vision, manual counting is prone to errors, resulting in tools being missed or lost without being discovered in time. Tools lost on the railway will cause major safety problems for running trains. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiment of the present invention provides a portable intelligent toolbox based on RFID technology, which can record the use of tools in a timely manner to avoid safety accidents caused by tools lost on the track, and automatically remind you when the tools are missing after the operation is completed. In view of the current pain points of railway tool maintenance, the portable intelligent toolbox based on RFID technology can realize intelligent and refined management of tools required for outdoor mobile operations.

[0005] Using RFID technology, this intelligent product, which consists of an ultra-high frequency RFID reader and multiple antenna units, can query, borrow, return, and take inventory of tools with RFID tags in the toolbox, and track the usage status of the tools in real time.

[0006] Convenient access, missing reminder alarm, and prompting users to return borrowed tools in time can reduce tool loss and reduce losses caused by tool out of control.

[0007] The present invention can transmit the status of tools in the tool box to the administrator's computer, so that the administrator can clearly understand the status of the tools and can remind the users to return the tools in time. The purpose of using this system is to enable the administrator to always effectively monitor the use of tools, prevent the loss of tools, facilitate the effective use of tools, avoid losses caused by improper tool management, and more importantly, prevent safety accidents caused by tools forgotten on the track, so as to nip them in the bud.

[0008] To achieve the above object, the present invention provides the following technical solution: a portable intelligent tool box based on RFID technology, comprising:

[0009] The box cover and the box body, one end of the box cover is equipped with a hinge, and the box cover is hinged to the box body through the hinge, and an upper buckle and a lower buckle are arranged between the other ends of the box cover and the box body, and the locking between the box cover and the box body is completed by the bite of the upper buckle and the lower buckle;

The reader / writer has a module self-check function to prevent the module from freezing or getting stuck, and automatically restarts when freezing.

[0012] RFID tag antennas are divided into active antennas. Antennas play a key role in the data communication between tags and readers. The energy for the chip startup circuit of the electronic tag to start working is obtained through the antenna in the electromagnetic field generated by the reader. In addition, the antenna determines the communication channel and communication method between the tag and the reader.

[0013] The antenna has a small physical size, which meets the needs of miniaturized tool boxes. It has omnidirectional or hemispherical coverage, which adapts to the small space in the tool box. It has high gain, which can provide the maximum signal to the tag chip, and the tool can choose a variety of electronic tags. The impedance matching is good, no matter what direction the tag is in, the polarization of the tag antenna can match the signal of the reader, which improves the reading efficiency of the electronic tag.

[0014] A charging port is provided on the top outer surface of the box lid on one side of the display screen. The charging port adopts a universal USB Type-C interface. The smart toolbox comes with a rechargeable battery. The battery charging port is located on the side of the display screen on the box lid surface and adopts a universal USB Type-C interface. It can be charged through a charger or a mobile power supply. It is easy to move and adapt to various field scenarios.

[0015] Furthermore, a switch is provided on the outer surface of the handle groove, and the output end of the switch is electrically connected to the power indicator light. The outer surface of the box cover is fixedly installed with a power indicator light and a buzzer. When the switch is turned on, the power indicator light is on, and the buzzer sounds when a tool missing alarm occurs.

[0016] Furthermore, a handle groove is provided at the center of the outer surface of the top end of the box cover, a handle is accommodated inside the handle groove, and the bottom end of the handle is movably connected to the inside of the handle groove, so that the handle stands upright when in use.

[0017] Furthermore, a display screen is fixedly mounted on one side of the top outer surface of the box cover. The display screen can be used to check the number of tools in the smart toolbox, the exact number of tools and their name numbers, and the battery power. The password can be entered through the display screen to complete personnel login and authorize employees to borrow and return tools.

[0018] Furthermore, a shoulder strap is provided on the outer surface of the box, and both ends of the shoulder strap are movably connected to the outer surfaces of both sides of the box, so the shoulder strap can be adjusted, which saves effort and is convenient to carry.

[0019] Furthermore, a shock-absorbing pad is pasted on the inner wall of the box, which reduces the collision between the tool and the box when the tool is placed in the box, thereby protecting the box, the tool and the electronic tag installed on the tool.

[0020] Furthermore, screw holes are provided on both sides of the bottom end of the protective cover plate, and the protective cover plate is fixedly connected to the box cover through the screw holes.

The password can be entered through the display screen 8 to complete personnel login and authorize employees to borrow and return tools.

[0049] The toolbox has a map positioning function. When the work is completed, if there are any missing tools, you can open the map to find the toolbox itinerary and find the lost tools according to the itinerary. The map search function can be performed through the WBE software or the handheld software.

[0050] When tools are not returned in time, the tool box will issue a warning and quickly identify the person responsible;

[0051] Fully automatic tool entry and exit record management eliminates the tedious and error-prone manual scanning and data entry work.

[0052] The smart toolbox has multiple wireless communication network interfaces, including WIFI, 4G, and wireless sensor networks, and supports remote wake-up. It supports Bluetooth 5.0 and can be directly connected to a mobile phone for spot inspection.

[0053] Remote monitoring can be carried out through WBE software and handheld software, information can be obtained anytime and anywhere, and automatic alarm can be given when tools are missing, thus reducing accidents caused by tool loss.

[0054] Through the smart toolbox, the usage history of each tool can be recorded, and the damage of the tool can be discovered in time and repaired or replaced.

[0055] When workers return tools, the RFID smart briefcase can automatically identify the returned tools and count them, reducing the time and errors of manual inventory.
