DETAILED DESCRIPTION

[0029] The following is combined with Figure 1 This application is described in further detail.

[0030] The present application embodiment discloses a closed-loop management system for a warehouse and a construction site. Figure 1 The closed-loop management system for warehouses and construction sites includes an electronic tag 1, an RFID data reading and writing device 2, a first RFID scanning device 3, a first RFID picking device 4, a second RFID scanning device 5, a second RFID picking device 6, a material vehicle, a third RFID scanning device 8 and a server 11.

[0031] The electronic tag 1 is attached to the material or the tool and records the name and model of the material and the tool. The RFID data reading and writing device 2 is connected to the server 11 for communication and is used to read and write the information of the electronic tag 1. Therefore, the information data of the material can be written into the electronic tag 1 through the RFID data reading and writing device 2 and the data can be transmitted to the server 11.

[0032] The first RFID scanning device 3 is placed in the warehouse and is connected to the server 11 for communication. The first RFID scanning device 3 is a handheld device that can scan the electronic tag 1 to read the information of the material and tool, and transmit this information to the server 11 to realize the entry and exit records of the material and tool.

[0033] The first RFID pickup device 4 can also read the information in the electronic tag 1 and is located at the entrance and exit of the warehouse. The first RFID pickup device 4 is connected to the server 11. When materials and tools enter or leave the warehouse, the first RFID pickup device 4 will automatically read the electronic tag 1 and transmit the reading result to the server 11. The staff can compare the reading result of the first RFID pickup device 4 with the scanning result of the first RFID scanning device 3 to reconfirm the entry and exit of materials and tools.

[0034] For example, when materials are shipped out of the warehouse, the existing first RFID scanning device 3 reads the information of the electronic tag 1 and records the shipment. After the materials are shipped out of the warehouse, the first RFID picking device 4 reads the information of the electronic tag 1 again to facilitate verification of the shipment of the materials.

[0035] The first RFID picking device 4 is arranged in the warehouse in the form of a suspended ceiling and is opposite to the warehouse floor, so as to accurately identify the electronic tag 1 .

[0036] A first direction identification device 9 is also provided in the warehouse. The first direction identification device 9 may adopt a laser sensor, a microwave sensor or an infrared sensor and is connected in communication with the server 11 to identify the in-and-out directions of personnel and materials.

[0037] The material cart is used to load materials or machinery, so when the materials are shipped out, they need to be placed in the material cart. The material cart is provided with a third RFID scanning device 8, which is in communication connection with the server 11. The third RFID scanning device 8 scans the electronic tag 1 on the material and binds it with the material or machinery. Therefore, the location of the material and machinery can be determined by the location of the material cart. The third RFID scanning device 8 is set as a handheld device for easy operation by the staff.

[0038] The material vehicle is also provided with a wireless communication module 7 which is connected to the server 11 for transmitting the location information of the material vehicle to the server 11. The wireless communication module 7 is preferably a 4G communication module with high stability. A WIFI communication module or the like may also be used.

[0039] The second RFID scanning device 5 and the second RFID picking device 6 are both installed at the construction site, and the second RFID scanning device 5 and the second RFID picking device 6 are both connected to the server 11 in communication. The second RFID scanning device 5 is a handheld device that can read the electronic tag 1 of the material and record the entry and exit of the material at the construction site. The second RFID picking device 6 is an RFID passage door. When the material vehicle enters or leaves the construction site, the second RFID picking device 6 reads the electronic tag 1 of the material. The staff can compare the reading result of the second RFID picking device 6 with the scanning result of the second RFID scanning device 5 to confirm the entry and exit of the material at the construction site.

[0040] In the embodiment of the present application, the staff can also periodically scan all the electronic tags 1 at the construction site through the second RFID scanning device 5 to determine the quantity and location of materials and equipment in the construction site, thereby realizing continuous dynamic management of the construction site.

[0041] The construction site is also provided with a second direction identification device 10, which may use a laser sensor, a microwave sensor or an infrared sensor and is communicatively connected with the server 11 to identify the direction of personnel and materials entering and leaving the construction site.

[0042] The implementation principle of the closed-loop management system for warehouses and construction sites in the embodiment of the present application is as follows: the electronic tag 1 is attached to the material or machine. The first RFID scanning device 3 scans the electronic tag 1 to read the information of the material and machine, and records the entry and exit of the material. The first RFID picking device 4 can also read the electronic tag 1 and compare it with the scanning result of the first RFID scanning device 3, so as to reconfirm the entry and exit of the material and machine.

[0043] When materials enter or leave the construction site, the second RFID scanning device 5 and the second RFID picking device 6 read the electronic tag 1 of the materials in turn. Therefore, the reading data of the electronic tag 1 by the first RFID scanning device 3 and the first RFID picking device 4 can be compared with the reading data of the electronic tag 1 by the second RFID scanning device 5 and the second RFID picking device 6, so as to monitor the synchronization of materials and tools in the warehouse and the construction site, and effectively reduce the probability of loss of materials and tools.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
