Description of the Drawings

[0021] Figure 1 : Block flow chart of the intelligent visual inspection method for storage materials of the present invention; Figure 2 : Block flow chart of the intelligent visual inspection system for storage materials of the present invention. Detailed Embodiments

[0022] The following combines Figure 1 and Figure 2 , and further describes the present invention: As Figure 1 shown, the intelligent visual inspection method for storage materials of the present invention includes the following steps: Step 1: The RFID reader / writer at the warehouse entrance reads the information in the RFID electronic tag on the goods or the goods packaging box, and exchanges information with the intelligent monitoring unit. The entrance RFID reader / writer obtains the location information of the storage shelf where the goods are placed and writes it into the RFID electronic tag on the goods or the goods packaging box; Step 2: The automatic vehicle transports the goods or the goods in the packaging box to the corresponding storage shelf according to the location information; Step 3: The weighing sensor on the shelf collects the weight of the goods and stores it in the RFID electronic tag on the shelf; Step 4: The drone compares the information from the intelligent monitoring unit with the information in the RFID electronic tag on the shelf to determine whether the quantity of goods is consistent; Step 5: The drone determines whether the quantity of goods is correct and whether the surface quality of the goods is qualified based on the image, and finally takes an inventory of the goods in the warehouse.

[0023] Among them, the goods or the goods packaging box represent two ways: the first way is that the goods have no packaging box, so the RFID electronic tag is directly fixed on the goods, and the second way is that the goods are placed in the packaging box, and the RFID electronic tag is directly fixed on the packaging box.

[0024] Specifically, in Step 1, an entrance RFID reader / writer is set at the warehouse entrance. The entrance RFID reader / writer can read the RFID electronic tag on the goods or the goods packaging box. The information in the RFID electronic tag at least includes the name, model, quantity, weight, and volume of the goods. The entrance RFID reader / writer sends the read information to the intelligent monitoring unit through a wireless transmission device for storage and calculation; The intelligent monitoring unit sends the shelf RFID electronic tag code corresponding to the storage shelf to the entrance RFID reader / writer. The entrance RFID reader / writer locates the shelf RFID electronic tag corresponding to the storage shelf based on the received signal strength (RSSI) and obtains the location information, and the entrance RFID reader / writer writes the location information into the RFID electronic tag on the goods or the goods packaging box.

[0025] In Step 2, the goods or the goods packaging box are placed on the automatic vehicle. The automatic vehicle at least includes a driving unit and a control unit. The control unit reads the storage shelf location information in the RFID electronic tag and controls the driving unit to make the automatic vehicle move to the corresponding storage shelf for manual or automatic unloading.

[0026] The driving unit may include a driving motor and wheels. The rotor of the driving motor drives the wheels to rotate through a transmission device, thereby driving the automatic vehicle to move forward or turn. The control unit includes a motor controller to control the speed and direction of the driving motor. The automatic vehicle also includes a positioning unit and a navigation unit. The former can locate the position of the automatic vehicle at any time, and the latter can detect obstacles.

[0027] Step 3: An RFID electronic tag for the shelf is provided on each storage shelf. The storage shelf has one or more layers. A weighing sensor is provided on each layer of the shelf to measure the total weight of the goods on that layer of the shelf. The weighing sensor can store the total weight data in the RFID electronic tag for the shelf.

[0028] In step 4, the drone receives an instruction from the intelligent monitoring unit to conduct an inventory of one or more goods. The intelligent monitoring unit sends the name, image, quantity, single weight, total weight, and the location information of the RFID electronic tag for the shelf to which the goods belong to the control unit of the drone. The RFID reader of the drone reads the information of the name and total weight of the goods on each layer of the shelf from the corresponding RFID electronic tag for the shelf. The control unit of the drone compares the information of the name, single weight, and total weight of the goods from the intelligent monitoring unit with the information of the corresponding goods name and total weight recorded in the RFID electronic tag for the shelf to determine whether the total weight of the corresponding goods is consistent and calculate whether the quantity of the goods is consistent.

[0029] In step 5, the drone takes an image of the goods with a high-resolution camera and compares it with the image of the goods from the intelligent monitoring unit to determine the name of the goods. After determining the name of the goods, the drone identifies and counts the quantity of the goods through a vision algorithm and takes a picture of the surface details of the goods with a high-resolution camera, and identifies cracks, dents, or damages through image analysis. When the following three conditions are met: 1. If the total weight of the goods read by the RFID reader of the drone is consistent with the total weight of the goods sent by the intelligent monitoring unit; 2. The quantity of the goods calculated by the high-resolution camera of the drone is also consistent with the quantity of the goods sent by the intelligent monitoring unit; 3. No cracks, dents, or damages are identified through image analysis; the inventory is completed, and the inventory result is sent to the server of the intelligent monitoring unit for storage. When any one of the above three conditions is not met, the drone sends an alarm message to the mobile terminal of the staff through the intelligent monitoring unit.

[0030] For example, the intelligent monitoring unit sends the inventory object information as an isolating switch, with a single weight of 10 kg and 5 on the shelf. When the RFID reader of the drone reads the information of the name and weight of the goods on each layer of the shelf from the RFID electronic tag on the shelf as "isolating switch" and the weight is 5 * 10 kg, it indicates that the quantity of the isolating switches on the shelf is correct.

[0031] The drone takes an image of the goods with a high-resolution camera and identifies and counts the quantity of the goods through a vision algorithm and takes a picture of the surface details of the goods with a high-resolution camera, and identifies cracks, dents, or damages through image analysis. When the following three conditions are met: 1. If the total weight of multiple disconnect switches read by the RFID reader of the drone is consistent with the total weight of the disconnect switches sent by the intelligent monitoring unit; 2. The number of disconnect switches calculated by the high-resolution camera of the drone through images is also consistent with the number of disconnect switches sent by the intelligent monitoring unit; 3. Through image analysis, it is identified that there are no cracks, depressions or damages on the surface of the disconnect switch; the inventory is completed, and the inventory result is sent to the server of the intelligent monitoring unit for storage; when any one of the above three conditions is not met, the drone sends an alarm message to the mobile terminal of the staff through the intelligent monitoring unit.

[0032] It can be seen that there are three-fold judgments in the inventory of materials in the present invention: First, calculate the quantity of goods by calculating the weight of the goods; Second, identify the quantity of goods through images; Third, identify whether the surface of the goods is intact through images. The first two are judgments of quantity, and the latter is a judgment of quality. The two judgments of the quantity of goods are because when different goods are placed together, it may happen that the weight is correct, so the second method is needed for supplementary judgment to ensure the correctness of the judgment result.

[0033] The mobile terminal in the present invention can also develop a goods management micro-application to realize functions such as material inbound and outbound management, inventory statistical analysis, and work order association, which helps to timely master the physical link of spare parts and ensure the efficient management and allocation of goods. The mobile terminal can be a mobile phone or a tablet computer.

[0034] In addition to the above functions, the intelligent monitoring unit in the present invention also integrates data of cross-professional systems such as ERP, PMS3.0, and Marketing 2.0, promotes a dynamic single map for goods management, and realizes traceability and queryability of the entire link of goods information. At the same time, it designs a function to export the full-process report of the replenishment package requirement form, intuitively showing the status of the replenishment package requirement form in the full process, so as to efficiently achieve the symmetry of information between the demand side and the supply side.

[0035] An exit RFID reader is provided at the exit in the RFID warehouse management platform.

The intelligent monitoring unit sends the name, image, quantity, single weight, total weight of the one or more goods to be counted, and the location information of the RFID electronic tag of the shelf to which the goods belong to to the control unit of the drone; the RFID reader of the drone reads the information of the name and total weight of the goods on each shelf in the RFID electronic tag of the corresponding shelf. The control unit of the drone compares the name, single weight and total weight information of the goods from the intelligent monitoring unit with the name and total weight information of the corresponding goods recorded in the RFID electronic tag of the shelf to determine whether the total weight of the corresponding goods is consistent and calculate whether the quantity of the goods is consistent.

10. According to the intelligent visual inspection system for storage materials according to claim 9, it is characterized in that: The drone uses a high-resolution camera to take images of the cargo and compares them with the cargo images from the intelligent monitoring unit to determine the name of the cargo. After determining the name of the cargo, the drone uses a visual algorithm to identify and count the number of cargoes, and uses a high-resolution camera to take pictures of the surface details of the cargo, and uses image analysis to identify cracks, dents or damage. When the following three conditions are met:

1. If the total weight of the goods read by the drone's RFID reader is consistent with the total weight of the goods sent by the intelligent monitoring unit; 2. The drone's high-resolution camera calculates the number of goods through images, which is consistent with the number of goods sent by the intelligent monitoring unit; 3. Use image analysis to identify that the goods have no cracks, dents or damage; The inventory is completed and the inventory results are sent to the server of the intelligent monitoring unit for storage; when any of the above three conditions is not met, the drone sends an alarm message to the staff's mobile terminal through the intelligent monitoring unit.
