[0002] In the existing RFID intelligent management system, tools can be placed arbitrarily in the toolbox (tool binding tags), that is, the tag antenna is arranged in any direction (the tag antenna is omnidirectional).

[0041] Embodiment 1

[0042] Figure 1 The schematic diagram of the structure of the toolbox management system based on RFID in the embodiment of the present disclosure is shown as follows: Figure 1 As shown, an RFID-based toolbox management system provided by an embodiment of the present disclosure includes a box body 1, a tool 2, an RFID reader / writer 3, an RFID tag 4 and an electromagnetic reflection single-negative metamaterial 5, wherein the RFID reader / writer 3 is arranged on the box body 1, the tool 2 is placed in the box body 1, each of the tool 2 is provided with a plurality of the RFID tags 4 along different directions, and the electromagnetic reflection single-negative metamaterial 5 is arranged on the inner wall of the box body 1.

[0043] Among them, the tool 2 is a metal tool, the RFID tag 4 is an anti-metal RFID tag, and the RFID tag 4 includes an RFID tag antenna. After the RFID reader / writer 3 transmits a detection signal in the box 1, the RFID tag 4 within the frequency response range of the detection signal can receive the detection signal and respond. The RFID reader / writer 3 can read the tag information of the RFID tag 4, thereby determining that the tool corresponding to the tag information is in the box 1, and counting the tools 2 in the box 1.

[0044] The position of the RFID reader 3 on the box 1 is fixed, and multiple RFID tags 4 are set on each tool 2 in different directions. No matter how the tools 2 in the box 1 are placed, at least one RFID tag 4 of the tool 2 can be recognized by the RFID reader 3, so that the tool 2 in the box 1 can be accurately identified. Among them, the RFID tag 4 that can be recognized by the RFID reader 3 can be a tag with a higher radiation frequency, such as facing the RFID reader 3 or having a shorter communication distance with the RFID reader 3, and the tag can be effectively recognized by the RFID reader 3. That is, in this embodiment, as long as the RFID reader 3 can recognize at least one from the multiple RFID tags 4 of the tool 2, the tool 2 can be identified, effectively avoiding the loss or omission of the tool 2 detection and identification.

[0045] Here, lost means that the tool 2 is identified, but the detection and identification result is not recorded. For example, in this embodiment, multiple RFID tags 4 of a tool 2 can be simultaneously identified by the RFID reader / writer 3, so that the tool 2 is identified, so that the loss of detection and identification of the tool 2 can be avoided based on the tag information of multiple RFID tags 4.

[0046] Omission refers to failure to identify the tool 2. For example, after the RFID reader 3 transmits a detection signal, among multiple RFID tags 4 of a tool 2, the first RFID tag facing the RFID reader 3 has a higher radiation frequency and is identified by the RFID reader 3; while the second RFID tag facing away from the RFID reader 3 has a lower radiation frequency and cannot be identified by the RFID reader 3. By determining that the tool 2 is located in the box 1 based on the first RFID tag, omission of the identification of the tool 2 can be effectively avoided.

[0047] The electromagnetic reflective single-negative metamaterial 5 is arranged on the inner wall of the box 1, so that the detection signal emitted by the RFID reader 3 can only propagate inside the box 1, and "electromagnetic reflection" will occur when encountering the box wall. On the one hand, it can effectively avoid misidentification of any other tags outside the box, and on the other hand, it can also enhance the communication reliability between the RFID reader 3 and the RFID tag 4, and accurately identify the tools 2 in the box 1.

[0048] The role played by the electromagnetic reflective single negative metamaterial 5 is similar to the effect of mirror reflection of light. Even if there is a corner blocked by the tool 2, the light source is more conducive to irradiating the blocked corner through the mirror reflection around the box 1, thereby identifying the tool 2 blocking the corner.

[0049] The professional term for "electromagnetic reflective single negative metamaterial" is "metamaterial with negative relative permittivity or negative relative permeability". Metamaterials can be divided into four categories according to the different values ​​of permittivity ε and permeability μ. The first quadrant is when both relative permittivity and relative permeability are positive (μr >0,ε r >0), that is, traditional materials in nature. At this time, electromagnetic waves can propagate in the material, which is represented by conventional electromagnetic dielectric materials, such as dielectrics. The second quadrant and the fourth quadrant are materials with negative relative permittivity or negative relative permeability (ε r <0 or μ r <0﹚, at this time, electromagnetic waves cannot pass through single negative materials, but exist in the form of evanescent waves. In a few cases, they exist naturally, such as plasma, magneto-optical materials, etc., that is, single negative metamaterials can reflect electromagnetic waves. The fourth quadrant is a material with both relative permittivity and relative permeability being negative (ε r <0,μ r <0), which is defined as a metamaterial, that is, a double-negative material, also known as a left-handed material, which does not exist in nature. It has the same properties as traditional materials. At this time, electromagnetic waves can propagate in the double-negative material and have negative refraction characteristics.

[0050] In this embodiment, a single negative metamaterial is used for electromagnetic reflection so that the RFID reader 3 can only identify the RFID tag 4 in the box 1, which can effectively avoid the interference of the signal outside the box 1 on the identification of the tool 2 and accurately identify the tool 2 in the box 1. For example, the signal outside the box 1 is identified as the RFID tag 4 of the first tool, but the first tool is not in the box 1, so the tool 2 is misidentified.

[0051] Optionally, the electromagnetic reflective single negative metamaterial 5 has a specific frequency, which is determined according to the spatial dimensions of the box 1, the number of tools 2 in the box 1, the properties of the tools 2, etc., so that the tools 2 in the box 1 can be counted quickly and accurately.

[0052] When the box 1 is a rectangular parallelepiped, the spatial dimensions of the box 1 may be the length, width, and height of the rectangular parallelepiped; the box 1 may also be a cube or a cylinder, etc. When the box 1 is a cylinder, the spatial dimensions include the radius or diameter of the bottom surface, the height of the cylinder, etc. Among them, the properties of the tool 2 include the material of the tool 2 (for example, whether the tool 2 is made of metal material) and the type of the tool 2 (for example, the tool 2 is a hammer, pliers, wrench, screwdriver, multimeter, wire finder, etc.).

[0053] The RFID-based toolbox management system provided by the embodiment of the present disclosure is provided with a box body 1, tools 2, RFID reader / writer 3, RFID tag 4 and electromagnetic reflective single-negative metamaterial 5. The RFID reader / writer 3 is arranged on the box body 1, and the tools 2 are placed in the box body 1. Each of the tools 2 is provided with multiple RFID tags 4 in different directions, and the electromagnetic reflective single-negative metamaterial 5 is arranged on the inner wall of the box body 1. It can utilize the multiple RFID tags 4 in different directions provided on the tools 2 and the reflective single-negative metamaterial 5 provided on the inner wall of the box body 1 to realize automatic, fast and accurate inventory of all tools 2 in the toolbox, effectively avoid the loss, omission and misidentification of the tools 2, thereby effectively preventing the power grid safety risks caused by the tools 2 being left in the running cabinet, adding a safety barrier to power production, and effectively reducing manual inventory, thereby improving the efficiency of toolbox inventory management.

[0054] In this embodiment, the automatic and rapid inventory function of tools 2 is realized through RFID technology, which can assist the user of the toolbox to automatically list and check the tools every time the toolbox is closed. If any tool 2 is missing, an alarm will be given to remind the user to return and place the tool 2 in time.

[0055] In some embodiments, Figure 1 As shown, the RFID reader / writer 3 includes an RFID read / write control unit 31 and an RFID read / write antenna 32. The RFID read / write control unit 31 is arranged outside the box 1, and the RFID read / write antenna 32 is arranged inside the box 1 and connected to the RFID read / write control unit 31. The RFID read / write control unit 31 controls the RFID read / write antenna 32 to transmit a detection signal inside the box 1, reads the tag information of the RFID tag 4 according to the detection signal, and manages the tool 2.

[0056] Under the condition that the convenience of using the tool 2 is not affected, multiple RFID tags 4 are bound to the same tool 2 in different directions. At the same time, "multiple RFID tags" or corresponding tag recognition logic are written into the RFID read-write control unit 31 to match the tool 2. The RFID read-write control unit 31 controls the RFID read-write antenna 32 to transmit a detection signal in the box 1, and the RFID read-write antenna 32 communicates with the tag antenna of the RFID tag 4, reads the tag information of the RFID tag 4, and identifies the tool 2 corresponding to the tag information. Since multiple RFID tags 4 are arranged in different directions on each tool 2, no matter how the tool 2 is placed in the box 1, at least one RFID tag antenna corresponding to the tool 2 can more advantageously communicate and identify with the reader antenna, effectively avoiding the loss or omission of the identification of the tool 2.

[0057] For easy operation, the RFID reader / writer 3 is installed on the upper cover of the box 1, wherein the RFID read / write control unit 31 is arranged on the outside of the upper cover, and the RFID read / write antenna 32 is arranged on the inside of the upper cover, so as to transmit a detection signal from the top of the tool 2, directly or obliquely to the tool 2 in the box 1, so as to detect and identify the tool 2.

[0058] In some embodiments, there are multiple RFID read / write antennas 32, and the multiple RFID read / write antennas 32 transmit the detection signal in turns.

[0059] The RFID read / write control unit 31 can write "multiple RFID read / write antennas" to control each RFID read / write antenna 32 to transmit a detection signal in turn, thereby realizing beam scanning, covering a more complete scanning space, and avoiding mutual interference between multiple antennas.

[0060] Exemplarily, there are four RFID read / write antennas 32, which are placed in an "E" shape on the inner side of the upper cover of the box body 1, and the RFID read / write control unit 31 writes "four RFID read / write antennas" to transmit detection signals in turns.

[0061] Optionally, the electromagnetic reflection single negative metamaterial 5 is laid on the side walls around the box 1 and the bottom wall of the box 1, and cooperates with the RFID read-write antenna 32 arranged on the inner side of the upper cover. The detection signal emitted from the top to the bottom by the RFID read-write antenna 32 can be reflected on the side walls around the box 1 and the bottom wall of the box 1, ensuring that the detection signal (the transmission power of the RFID read-write antenna 32) is only propagated in the box 1, and will be "electromagnetically reflected" when encountering the box wall. On the one hand, it can effectively avoid misidentification of any tags outside the box 1, and on the other hand, it can enhance the communication between the RFID read-write antenna 32 and the RFID tag antenna, and improve the detection and identification accuracy. In order to ensure the accuracy of the detection results and the interference of tags outside the box 1, the side walls around the box 1 and the bottom wall of the box 1 are covered with electromagnetic reflection single negative metamaterial 5.

[0062] In a specific implementation, the transmission power of the RFID read / write antenna 32 may be transmitted to the upper cover, so the electromagnetic reflective single negative metamaterial 5 may also be laid inside the upper cover.

[0063] In some embodiments, the RFID read / write control unit 31 includes an antenna configuration module, and the antenna configuration module determines the operating frequency of the RFID read / write antenna 32 and the RFID tag 4 within the corresponding frequency response range according to the spatial size of the box 1.

[0064] The RFID read / write control unit 31 determines the spatial dimensions (e.g., length, width, and height) of the box 1 according to the number and properties of the pre-installed metal tools 2. The spatial dimensions of the box 1 are the communication distance within the box 1. The RFID read / write control unit 31 determines the operating frequency (transmitting frequency) of the RFID read / write antenna 32 according to the communication distance, and determines the RFID tag 4 within the corresponding frequency response range, so as to identify the tool 2 through the communication between the RFID read / write antenna 32 and the RFID tag antenna.

[0065] In some embodiments, Figure 2 As shown, the RFID read-write control unit 31 includes a control display screen and a plurality of buttons arranged on the control display screen, wherein the buttons include a detection button. When the detection button is pressed, the tool detection state is entered. The RFID read-write control unit 31 detects the tool 2 in the box 1 according to the preset tool list and the received tag information of the RFID tag 4.

[0066] The control display screen is preferably a liquid crystal control display screen, which can display the inventory information of the tool 2 and control the management of the tool 2.

[0067] The detection button is a start detection button. After the start detection button is pressed, the tool 2 enters the automatic detection state. At this time, the RFID read-write control unit 31 obtains the preset tool list of the tool box, compares the tag information of the identified RFID tag 4 with the preset tool list, counts the tools 2 in the tool box, and determines whether there are any tools 2 that have not been returned after use. The preset tool list stores the name, quantity, and corresponding RFID tag information of the tools 2 pre-installed in the box body 1.

[0068] Each tool box can pre-set the detection time, for example, the detection time is 10 seconds. If all tools 2 are detected within 10 seconds after the detection button is pressed, the detection can be automatically stopped to improve the detection efficiency; if the detection time exceeds 10 seconds, the detection will automatically stop.

[0069] In the above embodiment, the RFID reader 3 automatically stops detection according to the detection time. In other embodiments, a stop detection button can also be set on the control display screen, and the stop detection button can be manually pressed after the tool 2 is detected or during the detection process to stop the detection. The detection button and the stop detection button can be the same detection button or different detection buttons.

[0070] In some embodiments, Figure 3 and Figure 4 As shown, the control display screen includes a tool management page, and the tool management page is used to display a detection record list generated according to the detection results of the RFID read-write control unit 31.

[0071] The detection record list may include a tool list 101 and a statistical menu 102. The tool list 101 displays the detection results of the tool 2. After the detection button is pressed, the tool 2 detection function is triggered, and the RFID read-write control unit 31 controls the RFID read-write antenna 32 to transmit a detection signal at a preset working frequency, and scans the RFID tag information in the box 1, compares the RFID tag information with the preset tool list, and generates a corresponding detection record list to display on the tool management page. The tool list 101 lists the names of the pre-installed tools 2. The detected tools 2 will be marked in the form of a "√" icon, and the undetected tools 2 will be marked in the form of an "×" icon, so that the user can intuitively view the detection results. The statistical menu 102 summarizes the detection results.

[0072] like Figure 3 and Figure 4 As shown, the tool management page can also display the current detection status. Figure 3 The "stop detection" state is displayed in the display. This state may be caused by the user pressing the stop detection button, and some tools 2 have not been detected. At this time, if the interval between the two detections is short, when the detection button is pressed again, the RFID read-write control unit 31 will ignore the detected tools 2, scan and identify the undetected tools 2, which can improve the detection efficiency and avoid re-detection and identification of the detected tools 2. The "stop detection" state may also be caused by insufficient memory of the RFID read-write control unit 31. When the RFID read-write control unit 31 clears part of the memory and presses the detection button again for detection, the RFID read-write control unit 31 can also ignore the detected tools 2, scan and identify the undetected tools 2, and avoid repeated identification and detection of tools 2.

[0073] Figure 4 The "detection completed" state is displayed in the middle, confirming that all tools 2 have been detected, and the user can press the stop detection button to exit the detection state.

[0074] It is understandable that when the tools 2 are counted through the above detection, the tools 2 are not taken out (the box 1 remains closed) to ensure the accuracy of the detection results. When the interval between two detections is short, the box 1 remains closed. Figure 3 and Figure 4 As shown, the tool management page can also display the detection time, etc.

[0075] In some embodiments, the box 1 is provided with an input / output interface, and the input / output device connected to the input / output interface interacts with the RFID read / write control unit 31 .

[0076] The input / output interface includes at least one of a USB interface and a Type-C interface. The input / output device may be a storage device such as a USB flash drive. After the input / output interface is connected to the RFID read / write control unit 31 through the input / output interface, the generated detection record list may be exported. The preset tool list may also be pre-stored in the input / output device and imported into the RFID read / write control unit 31 after the input / output device is inserted into the input / output interface.

[0077] In this embodiment, the RFID read-write control unit 31 can select a corresponding preset tool list from the RFID read-write control unit 31 or the input-output device according to the pre-installed tools 2 in the box 1. When the spatial size of the box 1 is fixed, different pre-installed tools 2 can be counted and managed, and the scope of application is wide (that is, the same box 1 can be used to manage different pre-installed tools 2).

[0078] In some embodiments, Figure 2 As shown, the button also includes a page turning button for turning the page of the tool management page; and / or

[0079] The buttons also include a refresh button, and the refresh button is used to refresh the page record; and / or

[0080] The buttons also include an export button, and the export button is used to export the detection record list.

[0081] The page-turning buttons include a page-up key and a page-down key. When the tools 2 in the above-mentioned tool list 101 exceed the preset types (for example, 14 types), the tool list 101 will automatically display in pages. The page-up key can switch page information forward (switch to the previous page), and the page-down key can switch page information backward (switch to the next page).

[0082] When the input-output device is not connected to the RFID reader 3, the refresh button is used to refresh the page record to restore it to a normal list state. When the input-output device is connected to the RFID reader 3, the export button can export the detection record list generated according to the detection result to the input-output device to reduce the memory usage of the RFID reader 3. The detection record list can be stored in the input-output device in a preset format, for example, in the form of an idcard1.txt document.

[0083] Since the refresh button and the export button are respectively executed when the input and output devices are not connected and connected, the two can be the same button.

[0084] like Figure 2 As shown, the buttons may also include a power switch button for controlling the on and off of the tool box management system to save energy.

[0085] Optionally, in this embodiment, the button can also be a combination button. For example, when the input and output device is inserted into the input and output interface, the page up button and the page down button are pressed at the same time (the page up button and the page down button constitute the first combination button), and the RFID read and write control unit 31 will automatically read the idcard1.txt document in the input and output device, and update the tool list list in the document to the internal storage record of the RFID read and write control unit 31. At the same time, the new tool list list will take effect immediately and the page will be refreshed. At this time, the input and output device can be unplugged, and the RFID read and write control unit 31 will detect the new tool list. For another example, press the page up button and the export button at the same time (the page up button and the export button constitute the second combination button), and the RFID read and write control unit 31 will clear all detection records to avoid the RFID read and write control unit 31 from having too much memory.

[0086] Embodiment 2

Figure 5 As shown, an embodiment of the present disclosure provides an RFID-based toolbox management method, which is applied to the above-mentioned RFID-based toolbox management system, wherein the RFID-based toolbox management system comprises a box 1, a tool 2, an RFID reader / writer 3, an RFID tag 4, and an electromagnetic reflection single negative metamaterial 5, wherein the RFID reader / writer 3 is arranged on the box 1, the tool 2 is placed in the box 1, and each tool 2 is provided with a plurality of RFID tags 4 along different directions, and the electromagnetic reflection single negative metamaterial 5 is arranged on the inner wall of the box 1, and the method comprises:

[0088] S101: The RFID reader / writer 3 transmits a detection signal in the box 1;

[0089] S102: the RFID reader / writer 3 reads the tag information of the RFID tag 4 in the box 1 according to the emitted detection signal;

[0090] S103: the RFID reader / writer 3 manages the tools 2 in the box 1 according to the tag information;

[0091] The electromagnetic reflective single-negative metamaterial 5 reflects the detection signal so that the detection signal propagates in the box 1 .

[0092] Specifically, the RFID reader / writer 3 transmits a detection signal in the box 1 through the RFID read / write antenna 32, and the tag antenna of the RFID tag 4 can communicate with the RFID read / write antenna 32. The RFID reader / writer 3 identifies the tag information of the RFID tag 4, thereby identifying the tools 2 in the box 1, counting the tools 2, and determining whether they have been returned after use.

[0093] The electromagnetic reflective single-negative metamaterial 5 is arranged on the inner wall of the box 1, so that the detection signal emitted by the RFID reader 3 can only propagate inside the box 1, and "electromagnetic reflection" will occur when encountering the box wall. On the one hand, it can effectively avoid misidentification of any other tags outside the box, and on the other hand, it can also enhance the communication reliability between the RFID reader 3 and the RFID tag 4, and accurately identify the tools 2 in the box 1.
