[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments 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.

[0036] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0037] Combination Figure 1-Figure 7 , an intelligent electronic label management device of the present invention includes a functional partition structure based on position layout, the structure includes:

[0038] The total reader allocation area is used to distribute radio frequency signals to coordinate read and write operations within the system;

[0039] A plurality of reader / writer A areas, each reader / writer A area includes at least one reader / writer A, and each reader / writer A corresponds to an electronic tag A, and the reader / writer A is used to read and write information of the corresponding electronic tag A;

[0040] A plurality of reader / writer B areas, each of which includes at least one reader / writer B, and each reader / writer B corresponds to an electronic tag B, and the reader / writer B is used to read and write information of the corresponding electronic tag B;

[0041] The outbound area is used to process the outbound operation of the goods after the read-write operation, and the outbound area is connected to the reader-writer A area and the reader-writer B area, so that the goods can enter the outbound area for the outbound process after the reader-writer A and the reader-writer B are operated;

[0042] The total reader / writer allocation area establishes a connection with the electronic tag through a radio frequency signal, and establishes a connection with the warehouse exit area through a radio frequency signal. The electronic tag is connected to the corresponding reader / writer area through a radio frequency signal to achieve two-way transmission and interaction of data;

[0043] A low-frequency antenna is arranged in the total read-write allocation area, and the low-frequency antenna is arranged at the top of the total reader-writer allocation area. At the same time, another group of low-frequency antennas is arranged in the warehouse exit area, and the other group of low-frequency antennas is arranged at the top of the warehouse exit area. The signals between the two groups of low-frequency antennas are interconnected;

[0044] The signal interconnection between the two groups of low-frequency antennas is achieved through the preset signal frequency and coding. The low-frequency antenna in the main reader distribution area sends a signal with a specific frequency and coding. The low-frequency antenna in the warehouse exit area receives and identifies the signal, and a communication link is established between the two. This interconnection can be used to transmit system startup and shutdown control signals. First, according to the preset frequency of 125kHz and Manchester coding, the low-frequency antenna module in the main reader distribution area generates a corresponding electrical signal through the internal signal generator. The signal generator generates a periodic oscillation signal at a frequency of 125kHz, and encodes the oscillation signal according to the coding rules to generate a coded signal.

[0045] The generated coded signal will be modulated, and the modulation circuit will modulate the amplitude of the coded signal accordingly according to the amplitude change requirements of the signal. Then, the modulated signal will enter the power amplifier circuit, which will increase the power of the signal to the preset transmission power of 3 watts;

[0046] The signal after power amplification is transmitted outward through the low-frequency antenna at the top of the main reader distribution area; the low-frequency antenna is designed to be suitable for the 125kHz frequency antenna structure, using a coil antenna to convert electrical signals into electromagnetic waves and radiate them into space. The emitted low-frequency electromagnetic waves will propagate in the storage environment and find the low-frequency antenna in the warehouse exit area for signal interaction.

[0047] An intermediate frequency antenna is arranged directly above each of the reader-writer areas. The intermediate frequency signal emitted by the intermediate frequency antenna has a moderate frequency, which can achieve relatively stable data transmission while ensuring a certain penetration capability. When the goods enter the reader-writer area, the signal emitted by the intermediate frequency antenna will activate the electronic tag on the goods. After receiving the intermediate frequency signal, the electronic tag loads the goods information stored in itself into the reflected signal through modulation technology, and then sends it back to the reader-writer. The reader-writer receives the reflected signal through the intermediate frequency antenna, demodulates and decodes the signal, and obtains relevant information about the goods.

[0048] Since the IF antenna is set just above the reader area, its signal coverage is mainly concentrated in the reader area. In actual operation, multiple IF antennas work together to ensure that the cargo tags in the entire reader area can be effectively read and written. When there are multiple cargoes in the reader area, the IF antenna can communicate with the electronic tags of different cargoes in turn through frequency division multiplexing technology to avoid signal conflicts.

[0049] A shelf is set up in the reader area, and a high-frequency antenna is vertically arranged on a column of the shelf. Four high-frequency antennas are arranged at the same height of the shelf columns at intervals. The four high-frequency antennas form a circular high-frequency antenna array, and the radiation direction of the antenna unit is toward the inside of the shelf;

[0050] In the annular high-frequency antenna array, the angle between adjacent antenna units of each group of the annular high-frequency antenna array is 90 degrees, and each antenna unit performs a directional beam with a beam width between 30 degrees and 60 degrees, and the antenna unit radiates signals toward the inside of the shelf;

[0051] The annular high-frequency antenna array is set up along the height direction of the shelf column, and the spacing between adjacent annular high-frequency antenna arrays is the same;

[0052] Four high-frequency antennas are spaced 90 degrees apart to form a circular high-frequency antenna array, so that all-round signal coverage can be achieved on the same height plane of the shelf. No matter where the goods are on the shelf, they can be covered by the signal of at least one antenna unit. This circular array design combined with directional beam technology ensures that goods at different positions inside the shelf can reliably interact with the high-frequency antenna. In addition, the spacing between adjacent circular high-frequency antenna arrays is the same, so that uniform signal coverage can be achieved in the vertical direction. According to the height of the shelf and the stacking of goods, the spacing between adjacent circular high-frequency antenna arrays can be reasonably set to ensure that all goods from the bottom to the top of the shelf can be covered by high-frequency signals. For example, for higher shelves, the spacing can be appropriately reduced and the number of layers of the circular high-frequency antenna array can be increased to ensure the integrity and continuity of the signal.

[0053] First, the radio frequency signal is started and generated. The low-frequency antenna at the top of the main reader distribution area starts to work and sends out low-frequency signals. The low-frequency signal has a long wavelength and can cover a large range. It is mainly used for the initialization of the entire system and a large range of signal sensing. Another group of low-frequency antennas at the top of the warehouse exit area are interconnected with the low-frequency antenna signals of the main reader distribution area to ensure that the warehouse exit area can also be covered by low-frequency signals when the system is started, in preparation for the subsequent goods outbound operation;

[0054] After receiving the radio frequency signal from the total reader allocation area, multiple reader / writer areas A and B begin to activate the readers / writers in their respective areas, including reader / writer A1, reader / writer A2, reader / writer A3, and reader / writer B1, reader / writer B2, and reader / writer B3.

[0055] The intermediate frequency antenna directly above each reader area is activated at the same time. The signal emitted by the intermediate frequency antenna can effectively penetrate ordinary packaging materials at a relatively close distance and communicate with the electronic tag corresponding to the reader. When the goods enter the reader area, the reader reads or writes the goods information in the electronic tag through the signal emitted by the intermediate frequency antenna, and collects the name, specification, quantity, and storage time of the goods.

[0056] After the goods have been operated by reader A and reader B, their electronic tag information has been updated or confirmed. When the goods are moved to the outbound area, the outbound area can quickly sense the arrival of the goods based on the low-frequency antenna and the previous signal interconnection with the main reader distribution area.

[0057] In the outbound area, the system will check the electronic tag information of the goods again to ensure the accuracy of the outbound goods, and then perform the outbound operation and record the outbound time.

[0058] The intelligent electronic tag management device includes a radio frequency identification module, a control and processing module, a communication module, a storage module, a display interaction module and a positioning navigation module. The radio frequency identification module includes a reader and an electronic tag. The reader is used to transmit a radio frequency signal to activate the electronic tag and receive a radio frequency signal carrying cargo information returned by the electronic tag. The electronic tag is attached to the cargo and is used to store cargo information.

[0059] The control and processing module includes a microcontroller and a signal processing circuit. The microcontroller is connected to the radio frequency identification module and is used to control the operation of the reader and receive the radio frequency signal transmitted by the reader. The signal processing circuit is used to process and analyze the received radio frequency signal to extract the cargo information in the electronic tag.

[0060] The communication module has a wired communication interface and a wireless communication module. The wired communication interface is used to perform stable wired data transmission with an external server. The wireless communication module is used to realize wireless data interaction with a mobile device or a remote monitoring system. The communication module is connected to the control and processing module to transmit processed cargo information to an external device and receive instructions from the external device.

[0061] The storage module is composed of a data storage unit and a database management system. The data storage unit is connected to the control and processing module and is used to store the cargo information extracted by the signal processing circuit and the system operation record. The database management system is used to manage and query the stored data.

[0062] The display interaction module includes a display screen and an input device, wherein the display screen is connected to the control and processing module and is used to display cargo information and system status, and the input device is used by an operator to input instructions and query requests to the control and processing module;

[0063] The positioning and navigation module includes a positioning system and a navigation system. The positioning system is used to determine the location of the goods in the warehouse. The navigation system is used to provide a cargo handling route for the handling equipment. The positioning and navigation module is connected to the control and processing module. The control and processing module performs inventory management according to the cargo location information provided by the positioning system and guides the operation of the handling equipment according to the route provided by the navigation system.

[0064] The intelligent electronic tag management device also includes real-time monitoring, which is achieved by setting sensors in the total reader allocation area, reader A area, reader B area and warehouse exit area. The sensors are used to collect location information, equipment operation status information and goods flow status information of each area. The real-time monitoring integrates and analyzes the collected information and transmits the information to the server through the communication module. The management device manages and coordinates the information interaction between the real-time monitoring module and the server.

[0065] In summary, high-frequency signals have high resolution and strong anti-interference capabilities. By forming a ring array of high-frequency antennas, the signal can be accurately focused inside the shelf, which is particularly suitable for reading and writing information on the electronic tags of small and delicate goods, effectively reducing signal leakage outside the shelf and avoiding interference with signals from other shelves or areas.

[0066] Secondly, the circular high-frequency antenna array can achieve all-round signal coverage on the same height plane of the shelf. No matter where the goods are on the shelf, they can be covered by the signal of at least one antenna unit. At the same time, the circular high-frequency antenna array with the same spacing is set along the height direction of the shelf column to ensure uniform signal coverage at different heights of the shelf, realizing effective management of goods on different layers on the shelf. This distribution and design method of high-frequency antennas fully utilizes the advantages of high-frequency signals and improves the reliability and efficiency of the management of small and precise goods.
