Description

Technical Field

[0001] The utility model relates to an assembled building construction technology, in particular to a prefabricated component steel frame recycling system based on RFID technology, which is specially used for recycling prefabricated component steel frames in an assembled production base. Background Art

[0002] With the rise and rapid development of prefabricated buildings, the types and quantities of prefabricated components are increasing. The storage and transportation of prefabricated components are one of the key links in the construction of prefabricated buildings. They directly affect the quality of the components and the construction progress. The steel frames used to transport prefabricated components are the key factors to ensure the safety and stability of the components during transportation. The steel frames not only provide solid support, but also help reduce vibration and damage during transportation. Considering cost savings, the demand for recycling prefabricated component steel frames is increasing.

[0003] Traditional recycling technology for prefabricated steel frames typically relies on manual operations and paper-based data records. This means that managers typically keep written records of the incoming and outgoing shipments of steel frames and prefabricated components, and manually update outgoing shipment information. This traditional recycling technology relies heavily on manual judgment and operation, making it prone to errors and inefficient. The lack of an effective traceability mechanism makes it difficult to track the flow and status of prefabricated steel frames, hindering their timely recycling. Alternatively, barcode recognition technology can be used. Barcode recognition technology is a technique used to automatically identify objects. Barcodes typically consist of a series of black and white stripes arranged in a certain pattern. A barcode scanner can scan the barcode to obtain item information. This technology is convenient, but suffers from a short recognition range, slow recognition speed, inability to recognize multiple tags simultaneously, and relatively limited data storage capacity.

[0029] The present invention will be further described in detail below with reference to specific implementation methods.

[0030] RFID (Radio Frequency Identification) technology is a contactless wireless communication technology that uses radio frequency signals to communicate data between RFID readers and RFID electronic tags, achieving the purpose of automatically identifying and tracking targets.

[0031] A prefabricated component steel frame recycling system based on RFID technology includes multiple RFID electronic tags, multiple RFID identification devices, multiple PDAs, and a background management system; one RFID electronic tag is installed on one prefabricated component steel frame, and the RFID identification device is installed at the entrance and exit of the prefabricated component warehouse. The PDA is a handheld operating device; the RFID identification device and the PDA are both equipped with an RFID reader, and the RFID reader has a built-in RFID antenna; when the prefabricated component steel frame installed with the RFID electronic tag passes through the RFID reader, the RFID identification device or the PDA emits a radio frequency signal through the RFID antenna and receives the radio frequency signal reflected back by the RFID electronic tag to collect data, and transmits the read data to the background management system via wireless communication.

[0032] RFID electronic tags use passive tags. Within the reading range of the RFID reader, the passive tags are triggered by the radio frequency signal emitted by the reader and reflect the radio frequency signal. The radio frequency signal emitted by the RFID reader provides the DC power required for the RFID electronic tags to work, without the need for additional power supply.

[0033] The RFID electronic tag is set on the side of the prefabricated component steel frame; the RFID electronic tag is an anti-metal RFID electronic tag adhered to the prefabricated component steel frame, or a foam resin sheet is set between the RFID electronic tag and the prefabricated component steel frame.

[0034] The RFID electronic tag includes a radio frequency module, a control module, a memory, and an antenna; the antenna is used to receive and transmit radio frequency signals; the radio frequency module is used to modulate and demodulate radio frequency signals, and the radio frequency module is connected to the antenna; the control module is connected to the radio frequency module and is used to process radio frequency signals and control the radio frequency module; the memory is connected to the control module for storing data; the control module contains the unique ID code and storage location information of the prefabricated component steel frame that has been pre-compiled.

[0035] A PDA (Personal Digital Assistant) is a portable, handheld device consisting of an RFID reader, a main control module, a wireless communication module, a camera, a touch screen, a storage module, and a power supply. The power supply powers the PDA. The RFID reader connects to the main control module, which collects and processes data. The wireless communication module connects to the main control module for data exchange with the backend management system. The touch screen connects to the main control module as an input device. The storage module connects to the main control module for data storage. The camera connects to the main control module as an input device. The PDA software management system on the handheld device enables personnel to manage operations such as steel frame registration and query, and enables timely data exchange with the backend management system.

[0036] The RFID reader uses an ultra-high frequency RFID reader.

[0037] The RFID reader consists of a power supply, a radio frequency module, a control and processing module, and an RFID antenna. The RFID antenna receives and transmits radio frequency signals. The radio frequency module modulates and demodulates the radio frequency signals and is connected to the RFID antenna. The control and processing module processes the radio frequency signals and controls the module. The power supply powers the RFID reader. The RFID reader uses its antenna to collect data by receiving radio frequency signals reflected from RFID tags attached to the steel frame.

[0038] The wireless communication method is WiFi communication.

[0039] The backend management system includes a server and a terminal display device connected to the server. The server is used to receive data sent by the PDA and RFID identification device, store detailed information of all prefabricated component steel frames and warehouse management data, and display them on the terminal display device.

[0040] The implementation process of the prefabricated steel frame recycling system based on RFID technology is as follows:

[0041] 1. Attach RFID electronic tags to the prefabricated steel frame;

[0042] 2. Install RFID identification devices at the entrances and exits of the warehouse. The RFID identification devices are equipped with RFID readers, and the RFID readers have built-in RFID antennas.

[0043] 3. Equip the PDA handheld device equipped with RFID readers for management personnel;

[0044] 4. When the steel frame is shipped out of the warehouse with the prefabricated components or when the steel frame is shipped into the warehouse, the RFID reader sends out radio frequency signals through the RFID antenna and receives the radio frequency signals reflected back by the RFID electronic tag to collect data;

[0045] 5. The read data is transmitted to the background management system via wireless communication, and the background management system performs data processing and steel frame information management.

[0046] In addition to the above-mentioned embodiments, the present invention can also be transformed as follows:

[0047] The RFID reader can be a high-frequency RFID reader, or it can be equipped with an ultra-high-frequency RFID reader and a high-frequency reader at the same time to adapt to reading at different distances.

[0048] Wireless communication can use Bluetooth communication, but the transmission distance of Bluetooth communication is short and it is more suitable for one-to-one communication. ZigBee communication can also be used, but ZigBee networking is complex and the cost is high.

[0049] RFID electronic tags can use active tags. Active tags need to be battery-powered and have a longer reading distance, but the battery needs to be replaced regularly, which is more expensive. RFID electronic tags can also use active tags. Active tags have a built-in power supply and can actively emit radio frequency signals.

[0050] These transformations are all within the protection scope of this utility model.

[0051] The above embodiments are preferred implementation methods of the present invention, but the implementation methods of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
