[0042] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] It should be noted that the step numbers in the text are only for the convenience of explaining the specific embodiment and do not limit the order of execution of the steps. The method provided in this embodiment can be executed by a related terminal device, and the following description is taken as an example of a processor as the execution subject.

[0044] like Figure 1 As shown, the first embodiment provides a method for identifying power warehouse devices based on RFID technology, including steps S1 to S3:

[0045] S1. Obtain device identification information of a device to be identified, and determine whether the RFID electronic tag information matches the pre-stored standard RFID electronic tag information; wherein the device identification information includes RFID electronic tag information, device image information, and device outline information;

[0046] S2. When the RFID electronic tag information does not match the standard RFID electronic tag information, judging whether the device to be identified has device stacking according to the device image information, or according to the device image information and device outline information;

[0047] S3. When device stacking occurs in the devices to be identified, the devices to be identified are adjusted according to the device profile information to reacquire new device identification information for device stacking identification.

[0048] It should be noted that the devices to be identified are power devices in the power warehouse, and each power device in the power warehouse has an RFID electronic tag.

[0049] As an example, in step S1, electromagnetic waves are sent through a pre-set RFID antenna to make the RFID electronic tag on the device to be identified feedback RFID electronic tag information, the current device image information of the device to be identified is collected through a pre-set image acquisition device, and the current device contour information of the device to be identified is collected through a pre-set microwave sensor. After obtaining the RFID electronic tag information of the device to be identified, the RFID electronic tag information of the device to be identified is compared with each standard RFID electronic tag information pre-stored in the RFID electronic tag information library. When the RFID electronic tag information of the device to be identified is consistent with any standard RFID electronic tag information in the RFID electronic tag information library, it is determined that the RFID electronic tag information of the device to be identified matches the standard RFID electronic tag information. When the RFID electronic tag information of the device to be identified is inconsistent with each standard RFID electronic tag information in the RFID electronic tag information library, it is determined that the RFID electronic tag information of the device to be identified does not match the standard RFID electronic tag information.

[0050] It can be understood that obtaining the current device contour information of the device to be identified based on the microwave induction principle can eliminate the interference of ambient light on the contour of the object to be identified.

[0051] In step S2, when the RFID electronic tag information of the device to be identified does not match the standard RFID electronic tag information, it can be determined whether device stacking occurs in the device to be identified based only on the current device image information of the device to be identified, or it can be determined in combination with the current device image information and device contour information of the device to be identified.

[0052] In step S3, when device stacking occurs in the devices to be identified, the devices to be identified are adjusted according to the current device outline information of the devices to be identified. For example, a device adjustment instruction is generated according to the device outline information, and the device adjustment instruction is sent to a pre-set device adjustment device such as a manipulator, and the manipulator and other device adjustment devices are driven to adjust the current placement position of the devices to be identified so that the devices to be identified no longer exist in the current device stacking situation, so as to re-acquire new device identification information for device stacking identification, and complete the identification of power devices in the power warehouse.

[0053] This embodiment uses the current device image information and device contour information of the device to be identified to perform stacking identification on the device to be identified based on the identification of the device to be identified according to the RFID electronic tag information. When the device to be identified is stacked, the device to be identified is adjusted so that the current device stacking situation no longer exists, and the adjusted device to be identified is re-identified. This makes it possible to accurately identify the power warehouse devices when device stacking occurs in the power warehouse devices, thereby better meeting the user's management needs for the power warehouse devices.

[0054] In a preferred embodiment, the power warehouse device identification method based on RFID technology further includes step S4:

[0055] S4. When the RFID electronic tag information matches the standard RFID electronic tag information, the device to be identified is placed according to the generated device placement instruction.

[0056] As an example, when the RFID electronic tag information of the device to be identified matches the standard RFID electronic tag information, it is considered that the device to be identified has been successfully identified at this time, and a device placement instruction can be generated according to the specified position corresponding to the device to be identified. The device to be identified is placed according to the device placement instruction. For example, the device placement instruction is sent to a pre-set robot or other device placement equipment, and the robot or other device placement equipment is driven to place the device to be identified at its corresponding specified position.

[0057] In a preferred implementation manner of this embodiment, after placing the device to be identified according to the generated device placement instruction, it also includes: when the device to be identified is successfully placed, sending the generated device placement information to the user terminal.

[0058] As an example, the device placement information includes an image taken when the device to be identified is placed at its corresponding specified position. After the device to be identified is successfully placed, an image of the device to be identified placed at its corresponding specified position is captured by a pre-set image acquisition device, such as a camera installed on a device placement device such as a robot, to generate device placement information, which is then sent to the user terminal via email or WeChat.

[0059] In a preferred embodiment, the power warehouse device identification method based on RFID technology further includes step S5:

[0060] S5. When the RFID electronic tag information matches the standard RFID electronic tag information, the standard RFID electronic tag information is marked as a priority comparison tag, and the number of successful matches of all priority comparison tags within a preset time period is counted, and all priority comparison tags are sorted according to the number of successful matches of each priority comparison tag.

[0061] As an example, considering that multiple electrical devices of the same type may be placed in the same area, when the RFID electronic tag information of the device to be identified matches the standard RFID electronic tag information, it is considered that the device to be identified has been successfully identified at this time, and the standard RFID electronic tag information can be marked as a priority comparison tag, and the number of successful matches of all priority comparison tags within a preset time period is counted, and the priority value of each priority comparison tag is determined according to the number of successful matches of each priority comparison tag. In the RFID electronic tag information library, all priority comparison tags are sorted in order from high to low according to the priority values ​​of each priority comparison tag, so that the RFID electronic tag information of the next device to be identified is preferentially compared with the priority comparison tag with the highest priority value in the RFID electronic tag information library, which is beneficial to improve the recognition efficiency of electrical devices in the power warehouse.

[0062] In a preferred embodiment, the method of determining whether device stacking occurs in the device to be identified based on device image information, or based on device image information and device outline information, is specifically as follows: determining whether the device image information matches pre-stored standard stacking image information; when the device image information matches the standard stacking image information, determining that device stacking occurs in the device to be identified; when the device image information does not match the standard stacking image information, continuing to determine whether the device outline information matches the pre-stored standard stacking outline information; when the device outline information matches the standard stacking outline information, determining that device stacking occurs in the device to be identified.

[0063] It should be noted that the standard stacking image information is image information obtained in advance based on common device stacking conditions, and the standard stacking contour information is contour information obtained in advance based on common device stacking conditions.

[0064] As an example, when the RFID electronic tag information of the device to be identified does not match the standard RFID electronic tag information, it is necessary to comprehensively consider the current device image information of the device to be identified, or the current image information and device contour information of the device to be identified to determine whether device stacking occurs in the device to be identified.

[0065] The current device image information of the device to be identified is compared with each pre-stored standard stacking image information. When the current device image information of the device to be identified is consistent with any standard stacking image information, it is determined that device stacking has occurred in the device to be identified. When the current device image information of the device to be identified is inconsistent with each standard stacking image information, in order to avoid inaccurate device image information caused by light problems, the current device contour information of the device to be identified is continued to be compared with each pre-stored standard stacking contour information. When the current device contour information of the device to be identified is consistent with any standard stacking contour information, it is determined that device stacking has occurred in the device to be identified.

[0066] In a preferred embodiment, the method of determining whether device stacking occurs in the device to be identified based on the device image information and the device contour information is specifically as follows: obtaining spectral image data of the device to be identified based on the device image information, and determining the actual material quantity of the device to be identified based on the spectral image data; when the actual material quantity of the device to be identified is not greater than the pre-stored standard quantity, continuing to determine whether the device contour information matches the pre-stored standard stacking contour information; when the device contour information matches the standard stacking contour information, determining that device stacking occurs in the device to be identified.

[0067] As an example, when the RFID electronic tag information of the device to be identified does not match the standard RFID electronic tag information, it is necessary to comprehensively consider the current image information and device contour information of the device to be identified to determine whether device stacking occurs in the device to be identified.

[0068] Taking into account that light may affect local images, but it is highly unlikely that the entire overall image will be affected, in this case, the spectral image data of the device to be identified can be obtained from the current device image information of the device to be identified, thereby achieving more accurate device stacking identification even when light affects local images.

[0069] The spectral image data of the device to be identified is obtained according to the current device image information of the device to be identified, and the actual material quantity of the device to be identified is determined based on the spectral image data. Since the actual material quantity of each electrical device is a fixed value, especially the material quantity of the outer surface of the electrical device, such as the outer surface material of the cable and the RFID electronic tag material on the cable, there are two materials in total. If the device to be identified is stacked with other electrical devices of different materials, the actual material quantity detected will definitely be greater than the standard quantity corresponding to the device to be identified. When the actual material quantity of the device to be identified is not greater than the corresponding standard quantity, it is considered that the device to be identified may also be stacked with other electrical devices of the same material. It is necessary to continue to compare the current device contour information of the device to be identified with each pre-stored standard stacking contour information. When the current device contour information of the device to be identified is consistent with any standard stacking contour information, it is determined that device stacking occurs in the device to be identified.

[0070] Based on the same inventive concept as the first embodiment, the second embodiment provides Figure 2The device for identifying a device for identifying a power warehouse based on RFID technology shown in the figure includes: an information acquisition module 21, which is used to obtain device identification information of a device to be identified, and to determine whether the RFID electronic tag information matches the pre-stored standard RFID electronic tag information; wherein the device identification information includes the RFID electronic tag information, the device image information and the device outline information; a stacking identification module 22, which is used to determine whether device stacking occurs in the device to be identified according to the device image information, or according to the device image information and the device outline information when the RFID electronic tag information does not match the standard RFID electronic tag information; a device adjustment module 23, which is used to adjust the device to be identified according to the device outline information when device stacking occurs in the device to be identified, so as to re-acquire new device identification information for device stacking identification.

[0071] In a preferred embodiment, the power warehouse component identification device based on RFID technology further includes: a component placement module for placing the component to be identified according to the generated component placement instruction when the RFID electronic tag information matches the standard RFID electronic tag information.

[0072] In a preferred embodiment, the power warehouse device identification apparatus based on RFID technology also includes: a tag sorting module, which is used to mark the standard RFID electronic tag information as a priority comparison tag when the RFID electronic tag information matches the standard RFID electronic tag information, and count the number of successful matches of all priority comparison tags within a preset time period, and sort all priority comparison tags according to the number of successful matches of each priority comparison tag.

[0073] In a preferred embodiment, the method of determining whether device stacking occurs in the device to be identified based on device image information, or based on device image information and device outline information, is specifically as follows: determining whether the device image information matches pre-stored standard stacking image information; when the device image information matches the standard stacking image information, determining that device stacking occurs in the device to be identified; when the device image information does not match the standard stacking image information, continuing to determine whether the device outline information matches the pre-stored standard stacking outline information; when the device outline information matches the standard stacking outline information, determining that device stacking occurs in the device to be identified.

[0074] In a preferred embodiment, the method of determining whether device stacking occurs in the device to be identified based on the device image information and the device contour information is specifically as follows: obtaining spectral image data of the device to be identified based on the device image information, and determining the actual material quantity of the device to be identified based on the spectral image data; when the actual material quantity of the device to be identified is not greater than the pre-stored standard quantity, continuing to determine whether the device contour information matches the pre-stored standard stacking contour information; when the device contour information matches the standard stacking contour information, determining that device stacking occurs in the device to be identified.

[0075] In summary, the implementation of the embodiments of the present invention has the following beneficial effects:

[0076] By acquiring device identification information of the device to be identified, the device identification information includes RFID electronic tag information, device image information and device outline information, and judging whether the RFID electronic tag information matches the pre-stored standard RFID electronic tag information, when the RFID electronic tag information does not match the standard RFID electronic tag information, judging whether the device to be identified has device stacking according to the device image information, or according to the device image information and the device outline information, when the device to be identified has device stacking, adjusting the device to be identified according to the device outline information, so as to re-acquire new device identification information for device stacking identification, and completing the identification of the power devices in the power warehouse.
