[0023] This embodiment provides an intelligent engineering management system based on RFID, and its specific technical solution is as follows:

[0024] like Figure 1 The RFID-based intelligent engineering management system shown includes:

[0025] Warehouse units of construction projects, storage units and outbound units of said warehouse units;

[0026] The warehouse unit is used to store raw materials and construction tools used in the construction process of the construction project. The warehouse unit includes an automatic shelf 1, a placement box 2 placed on the automatic shelf 1, and an RFID radio frequency tag 3 set on the placement box 2; the RFID radio frequency tags 3 on different placement boxes 2 store the names, specifications, models and quantities of the raw materials or construction tools in the corresponding placement boxes 2;

[0027] The warehouse unit also includes a warehouse, i.e., a house set up in an enterprise or a construction site specifically for storing raw materials and construction tools. The warehouse can be a reinforced concrete structure, a steel structure house, or a temporary house built with movable panels according to the location of the warehouse; the automatic shelf 1 is installed in the warehouse, and the automatic shelf is longitudinally provided with multiple layers of placement layers, each layer is provided with an equal number of placement boxes 2, and different raw materials and construction tools are placed in each placement box 2. For raw materials with relatively large demand, they can be allocated to multiple placement boxes 2 for storage;

[0028] The storage unit is used to register and manage the raw materials and construction tools entering the warehouse unit, and the storage unit includes a first RFID radio frequency identification device 4 and a barcode scanning device 10; the barcode scanning device 10 is used to scan the barcodes on the packaging boxes or packaging bags of the purchased raw materials. It is well known to those skilled in the art that the barcodes on the packaging boxes or packaging bags of the raw materials purchased by the barcode scanning device 10 can obtain the names and specifications of the corresponding raw materials and construction tools; and the first RFID radio frequency identification device 4 can identify the information in the RFID radio frequency tag 3 on the side of the placement box 2, which is used to realize the information confirmation of the raw materials and construction tools in the placement box 2 at the storage stage;

[0029] The outbound unit is used to register and manage the outbound raw materials and construction tools, and the outbound unit includes a second RFID radio frequency identification device 5; the second RFID radio frequency identification device 5 can identify the information in the RFID radio frequency tag 3 on the side of the placement box 2, and is used to realize the information confirmation of the raw materials and construction tools in the placement box 2 during the outbound stage;

[0030] Also includes:

[0031] A computer 6, wherein the computer 6 is communicatively connected to the automatic shelf 1, the first RFID radio frequency identification device 4, the barcode scanning device 10, and the second RFID radio frequency identification device 5; the computer 6 is communicatively connected to a display terminal 7 and an input terminal 8;

[0032] The computer 6 is configured with a storage module for storing data information in the management process. Of course, if the storage capacity of the computer 6 itself cannot meet the usage requirements, a storage server connected to the computer can be configured to store the data in the management process through the storage server; the information scanned by the first RFID radio frequency identification device 4, the barcode scanning device 10 and the second RFID radio frequency identification device 5 are all transmitted to the computer 6, and the automatic shelf 1 can perform the warehousing and outbound transmission operations of raw materials or construction tools according to the warehousing and outbound instructions of raw materials or construction tools sent by the computer 6.

[0033] In this embodiment, the automatic shelf 1 is provided with a mechanical arm for picking up and placing goods, and the mechanical arm is provided with a third RFID radio frequency identification device 11; wherein the automatic shelf 1 can be an automatic shelf 1 with a mechanical arm in the prior art, for example, the automatic shelf for catching goods disclosed with the authorization announcement number CN212268502U can be used. When this form of automatic shelf is adopted, the conveying device inside the frame machine in the prior art is arranged near the entrance and exit of the warehouse (it can be understood that the exit and entrance of the warehouse are the same) to facilitate the warehouse manager to pick up and place raw materials or construction tools from the conveying device; the third RFID radio frequency identification device 11 on the mechanical arm can identify the RFID radio frequency tag 3 on the side of the placement box 2 on the automatic shelf 1, obtain the information of the employee of the RFID radio frequency tag 3, so as to determine the name, specification and model of the raw materials or construction tools in the current placement box 2. If it is the placement box 2 corresponding to the required raw materials or construction tools, the mechanical arm takes down the placement box 2 and conveys it to the manager's workstation through the conveying device.

[0034] In this embodiment, the automatic shelf 1 has a controller, which is in communication with the computer 6. The controller can receive control instructions from the computer 6 to control the automatic shelf to automatically pick up and place goods. The controller can adopt a Siemens S7-200 PLC controller.

[0035] In this embodiment, the side of the placement box 2 having the RFID tag 3 faces the side where the robot arm operates, so that the third RFID device 11 on the robot arm can easily identify the RFID tag on the side of the placement box 2.

[0036] In this embodiment, the outbound unit also includes a face recognition camera 9, which is communicatively connected to the computer 6; the face recognition camera 9 is used to capture facial images of personnel who pick up materials and perform facial feature recognition to facilitate comparison of background personnel information to confirm whether they are employees of this enterprise or this project.

[0037] In this embodiment, in order to facilitate the accurate identification and positioning of the position of each placement box 2 in the automatic shelf 1, a QR code label 12 is provided on the lower side of each placement box 2 on each automatic shelf 1, and a camera is also installed on the robotic arm. The camera can capture the image of the label to achieve accurate positioning of the target position of the robotic arm for picking up and placing goods. The technology of using a camera and a QR code label 12 to position the robotic arm is an existing technology (for example, the technology disclosed in the Chinese invention patent with application publication number CN117602253A), which will not be repeated here.

[0038] The working process of the RFID-based intelligent engineering management system provided by the utility model is as follows:

[0039] The cargo management of the automatic shelf 1 is based on the form of the automatic shelf 1 used in this embodiment. A plurality of placement boxes 2 provided with RFID radio frequency tags 3 are placed on each layer of the automatic shelf 1. Before placing the placement boxes 2 on the automatic shelf 1, the corresponding material information placed in the placement boxes 2 at different positions on the automatic shelf 1 needs to be completed. The process is as follows:

[0040] First, the manager posts a QR code label on the automatic shelf 1. The manager scans the prepared QR code label 12 through the barcode scanning device 10 (it can be understood that the barcode scanning device 10 used in this embodiment also has a QR code scanning function), and then inputs the label of the location where the placement box 2 for placing welding rods corresponds to the QR code label 12 through the input terminal, and then posts the QR code label 12 on the automatic shelf 1, and so on, until the QR code labels 12 corresponding to different materials are posted at the locations of the automatic shelf 1 corresponding to all the placement boxes 2 of the automatic shelf 1;

[0041] Secondly, the manager edits the material information corresponding to the RFID tags 3 on different placement boxes 2 through the cooperation of the first RFID radio frequency identification device 4 and the input terminal 8, and edits the layer of the automatic shelf 1 corresponding to the placement box 2 corresponding to each RFID radio frequency tag 3 through the input terminal 8. For example, welding rods are placed in a placement box 2, and the placement box 2 is placed on the fifth layer of the automatic shelf. When the manager inputs information through the input terminal 8, he first scans the RFID radio frequency tag 3 on the side of the placement box 2 through the first RFID radio frequency identification device 4, and then enters the material stored in the current placement box as welding rods through the input terminal 8 (and enters the model and specifications of the welding rods at the same time), and then enters the material stored in the placement box through the automatic shelf 1. The conveying device conveys the placement box 2 to a position where the robotic arm can grab it. During the process of the robotic arm grabbing the placement box 2, the third RFID radio frequency identification device 11 on it recognizes the material information of the RFID radio frequency tag 3 on the placement box 2, and transmits it to the controller. The controller then feeds back to the computer 6. The computer sends a control signal to the controller according to the layer of the automatic shelf 1 where the placement box 2 is located. The controller controls the servo motor that drives the robotic arm to move up and down to the corresponding layer of the automatic shelf 1. Then the robotic arm runs, obtains the QR code label of the layer through the camera on the robotic arm, and after locating the position corresponding to the material, the robotic arm places the placement box 2 on the position of the automatic shelf 1 corresponding to the QR code label.

[0042] Storage of raw materials and construction tools (hereinafter referred to as materials):

[0043] After the purchased materials are transported to the warehouse, the manager scans the barcode information on the material packaging through the barcode scanning device 10 to obtain at least the name information of the material, and then the computer determines the location where it needs to be stored based on the obtained name information, and then sends a release instruction to the control of the automatic shelf 1, and then the controller controls the mechanical arm to reach the position of the placement box 2 corresponding to the material on the automatic shelf 1, and after taking the placement box 2, it is transported to the manager by the conveying device, and the first RFID radio frequency identification device 4 identifies the information of the placement box 2 to confirm that the placement box 2 is the placement box 2 for storing the current material, and then the manager puts the material into the placement box 2, and then inputs the warehousing instruction through the input terminal, and then the conveying device and the mechanical arm put the placement box 2 with the material placed in the corresponding position on the automatic shelf 1 in turn (this process is the same as the second step of the stacking management of the automatic shelf 1);

[0044] Delivery of raw materials and construction tools (hereinafter referred to as materials):

[0045] The person who needs to pick up the materials, carries the signed and reviewed item pick-up slip (the item pick-up slip can be paper or an electronic work order generated by the company's internal OA management system) to the manager, and completes the information confirmation and recording of the person picking up the materials through the face recognition camera 9. The manager inputs the material information to be picked up through the input terminal 8 according to the material information received, and then the computer sends the picking information to the controller, and the controller controls the mechanical arm and the conveying device to complete the picking operation, and conveys the placement box 2 of the corresponding material to the manager. The manager identifies the information of the placement box 2 through the second RFID radio frequency identification device 5, and has determined that the placement box 2 is the target placement box 2. The manager then ships the goods, and then inputs the warehousing instruction through the input terminal 8, and then puts the placement box 2 back to the corresponding position;

[0046] It can be understood that after completing the cargo management of the automatic shelf 1, no matter whether the material is put into or taken out of the warehouse, the process when the robotic arm locates the placement box 2 of the corresponding material is consistent, that is, the computer first determines the specific layer of the automatic shelf 1 where the current material is located, and then the camera on the robotic arm obtains the QR code label information to obtain the specific location of the material, and then the robotic arm runs to the exact position of the placement box 2 corresponding to the material, and then the third RFID radio frequency identification device 11 identifies the specific material information of the placement box 2 to ensure that the placement box 2 taken away is correct.

[0047] In summary, when taking the placement box 2, the RFID-based intelligent engineering management system provided by the utility model first inputs the information of the material to be taken through the input terminal, obtains the specific layer on the automatic shelf 1 where the material is located, and the controller controls the servo motor to drive the mechanical arm to the specified layer. The camera identifies the QR code label 12 to accurately locate the mechanical arm to pick up the goods. Before picking up the goods, the third RFID radio frequency identification device 11 on the mechanical arm identifies the RFID radio frequency tag 3 on the placement box 2 to confirm the accuracy of the placement box 2. When the placement box 2 is transmitted to the management personnel, the second RFID radio frequency identification device 5 is used to identify the information of the RFID radio frequency tag 3 of the placement box 2 again, and the material in the placement box 2 is confirmed again, thereby ensuring the accuracy of picking up the goods through a multi-level confirmation method; and, by setting a face recognition camera 9 to perform personnel identity recognition and confirmation, it is avoided that others claim the goods by false claim.

[0048] In the specific implementation of the present invention, the first RFID radio frequency identification device 4 and the second RFID radio frequency identification device 5 can be combined into one, that is, a first RFID radio frequency identification device 4 is set to serve as an identification device for the RFID radio frequency tag 3 during the storage and outbound processes.

[0049] The above are only preferred embodiments of the present invention and are 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.
