Description

Technical Field

[0001] The utility model belongs to the technical field of tool boxes, and in particular relates to an intelligent tool box based on RFID. Background Art

[0002] Many different kinds of tools are used in various operations such as power emergency repairs, outdoor operations, and daily repairs. These tools are of many types and in large numbers, and are usually stored in an ordinary toolbox. Problems such as tool loss, wrong installation, and mixing often occur.

[0003] At present, in order to avoid the situation of incomplete tools during operation and lost tools after operation, strict inventory is usually required during preparation, transfer during operation, and sorting after operation to reduce the omission of tools. However, counting tools wastes a lot of time, which is not only inefficient, but also greatly reduces the success rate. It is difficult to avoid the phenomenon of mixed loading and mixing of multiple tool boxes, and the use of tools lacks effective supervision, and the frequency of tool use cannot be effectively counted. At the same time, when the tools are found to be lost during the on-site inventory, they often need to invest a lot of energy to find them because the location where the tools were left is relatively hidden or inconspicuous, and the success rate of retrieving them is extremely low. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the examples of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1 , 2As shown in FIG. 3 , the smart toolbox of this embodiment includes a toolbox body 1, a human-computer interaction module 2, a push-type induction switch 3, an RFID antenna 4, a power module 5, and a smart management module 6. Tools with RFID tags are placed in the smart toolbox.

[0018] The toolbox box body 1 is used to store tools with RFID tags and a support structure for installing other modules. The toolbox box body 1 includes a box cover 1.1, a locking structure 1.2, a handle 1.3, a box shell 1.4, an RFID signal shielding film 1.5 for the box body / box cover, an upper partition 1.6 with a limiting groove, and a lower partition 1.7; the locking structure 1.2 is an existing structure, and the box cover 1.1 can be buckled on the box shell 1.4. The box shell 1.4 is composed of a partition 1.41, and limiting slot structures 1.42 are also provided on both sides of the partition 1.41. The above-mentioned limiting slot structure 1.42 is an existing structure, and it can be combined into a box.

[0019] The upper partition plate 1.6 and the lower partition plate 1.7 with the limiting groove 1.8 are customized according to the size of each tool, so as to fix the position of the tool.

[0020] The RFID signal shielding film 1.5 is used for shielding RFID signals inside and outside the box. The signal shielding film 1.5 of the box body 1.1 is laid between the box body shell and the upper partition plate 1.6 and the lower partition plate 1.7.

[0021] There are two groups of RFID antennas 4, one group is a built-in antenna 4.1 inside the box, and the signal is limited inside the box by the RFID signal shielding film 1.5 inside the box, which is used to read the RFID tag information inside the box; the other group is an external antenna 4.2, which is used to read the RFID tag information outside the box for device detection.

[0022] The box cover 1.1 includes an upper cover and a lower layer. A human-machine interaction module 2, an intelligent management module 6, an RFID signal shielding film 1.5, etc. are installed in the middle of the upper cover. Small holes are provided on the RFID signal shielding film 1.5 to facilitate the layout of antennas and power cords into the box; module installation slots / holes are provided on the upper cover of the box cover 1.1 to facilitate the installation of various modules. These modules can be integrated by glue filling for the purpose of waterproofing, dustproofing and protection; the lower layer of the box cover 1.1 is provided with installation slots for built-in antennas 4.1 and power modules 5.

[0023] The purpose of the tools with RFID is to use RFID tags to number each tool. They are placed in the fixed tool limit slots in the tool box so that the RFID antenna on the box cover can successfully obtain the tag number of each tool for analysis.

[0024] The human-machine interaction module 2 includes a display screen 2.1, an operation button 2.2, a transparent cover 2.3, an LED indicator light, a buzzer, etc. The operation button 2.2 is arranged at the lower end of the display screen 2.1, and the transparent cover 2.3 is arranged above the display screen 2.1 by a rotation. The rotation structure is an existing structure, which can be an existing shaft rotation, etc., or the transparent cover 2.3 can be directly covered on the display screen 2.1.

[0025] The display screen 2.1 can provide function menus for human-computer interaction, display equipment inventory status and other information; the operation button 2.2 can include a function selection button, a confirmation button, and a power button / wake-up button. The function selection button is mainly used to select the functions of the human-computer interaction interface, including [screen display mode], [inventory mode], [registration mode], [detection mode], [return] and other function menu selections. The confirmation button confirms the function menu selection. The power button / wake-up button is used to start or wake up the device; the LED indicator light can be a red and green dual-color LED light. By adjusting the LED color and flashing frequency, the device operation status is indicated. The green light is always on for the normal operation mode of the device, the green light flashes for the inventory / detection mode, the red light is always on for the device registration mode, and the red light flashes for the alarm mode; the buzzer is mainly used for the result prompts in each operation mode. In the registration / inventory mode, a short buzzer sounds every time a device is scanned, and two long buzzers are sounded when the scan is completed. After the code is scanned, a rapid buzzer sounds for 30 seconds if an abnormality is found, or the buzzer is interrupted by clicking a button. The above are all existing technologies and can be set as needed.

[0026] The push switch 3 is arranged on the tool box cover, specifically at the joint of the upper and lower covers. When the tool box is closed, the push switch is pressed, and when the tool box is opened, the push switch pops up, which is mainly used to trigger the opening and closing events.

[0027] The intelligent management module 6 is the intelligent mainboard of the toolbox, which is mainly composed of MCU, memory, clock circuit, power interface, display interface, button interface, RFID reading module, RFID antenna interface, etc. The intelligent management module realizes the driving and calling of each module interface, thereby realizing the intelligent management of the toolbox tools.

[0028] The hardware composition of this embodiment is shown in the figure Figure 4 As shown. The hardware involved in this embodiment includes: display screen, button, LED indicator light, buzzer, RFID antenna, MCU, RFID reading module, and battery are all existing products. The RFID reading module can be an existing RFID reader. The power module 5 includes a battery arranged in a battery slot.

[0029] The MCU can be equipped with existing programs according to specific needs. In this embodiment, as one of the implementation methods, the management system functions carried include toolbox tool initialization / registration, tool inventory, object detection, usage registration, record viewing, system management, and data export functions. System functions such as Figure 5 shown.

[0030] Among them: Toolbox tool initialization / registration is used to register and manage tools. It is usually used when the toolbox is used for the first time or when the tool is replaced / updated. The system drives the built-in antenna in the box to perform RFID scanning, and the acquired tool tag information (through the established coding specifications, the production date, validity period, tool category, etc. of the tool can be quickly parsed) is parsed and stored in the system database. The above parsing process is an existing technology, and those skilled in the art can select an existing parsing method according to the existing technology.

[0031] The tool inventory uses the RFID antenna in the box to scan the tools in the box, and compares the scanned number information with the number in the tool box database to determine whether the tools are installed incorrectly or missing. If there is an abnormality, a buzzer and LED flashing reminder will be issued. The comparison of the above number information is also an existing technology. If it is consistent, no reminder will be issued, but if it is inconsistent, the above reminder will be issued.

[0032] Object detection is the object-finding mode. This mode uses the toolbox's external antenna to detect tools outside the box. When an object with an RFID tag is detected (the system can be configured to only match tools registered in the toolbox database), a 1s / time beep and a red LED flash are emitted. At this time, we can try to move the toolbox. When we carry the toolbox close to the object, the LED flashes faster and the beep becomes more rapid. When we move away from the object, the beep slows down. This method mainly uses the change in RFID signal strength to make judgments, thereby realizing device detection within a radius of 5 meters, thereby solving the problem of our tools not being found, and even helping us find previously lost objects. The above time and distance can be set as needed.

[0033] Usage registration is used for the registration and management of device usage. The RFID antenna in the box is used to scan the tools in the box. By comparing the scanned number information with the number in the tool box database, the information of the tools taken away is automatically registered and recorded. For example, as one of the implementation methods, there are two ways to start the usage registration:

[0034] First, directly start scanning the code by pressing the button to register the items taken away;

[0035] Second, driven by the closing box event, if there is a misinstallation during inventory, an audible and visual alarm will be activated. If a tool is missing during inventory, it will be considered that the tool has been taken, and a usage log will be recorded at the same time.

[0036] Users can view relevant record information by selecting [Unpacking Event Record], [Tool Usage Record], [Log Record], etc. The generation of relevant record data is as follows:

[0037] The data of unpacking event recording is mainly driven by the push switch between the box cover and the box body. When the tool box is opened, the piezoelectric switch pops up and the system records the unpacking event; when the tool box is closed, the piezoelectric switch is pressed, and the system records the closing event. At the same time, the system starts the automatic inventory countdown (the default is 3 minutes, which can be configured and modified) and records relevant logs.

[0038] Tool usage record data is mainly recorded through manual scanning registration and closed box scanning registration.

[0039] The log record data mainly includes operation records, RFID execution records, unpacking events, etc.

[0040] System management is used to configure system operation parameters, mainly including the countdown threshold for automatic inventory counting (the default is 3 minutes), whether to predict that the box is closed during inventory counting (the default is yes), whether to judge that the box is closed during detection (the default is yes), and whether to judge that the box is closed during registration (the default is yes).

[0041] The recording and judgment processes involved in the above procedures are existing procedures, and staff can set them up as needed.

[0042] Data export mainly means that after the user inserts the mobile storage medium through the USB interface, the system can manually export the toolbox's registered tool information, tool usage records, inventory records, log records, etc.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
