Technical Field
[0001] The present invention relates to the technical field of intelligent storage cabinets, and in particular to an intelligent cabinet for intensively reading bank reserved signature cards and a management method thereof. Background Art
[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.
[0003] The traditional storage method for bank reserved signature cards is to keep them in a safe at the counter office or in important departments. Staff must register card access records every day. This storage method is labor-intensive and cannot be monitored in real time, which poses the risk of card loss and leakage.
[0004] In order to improve the management efficiency of reserved signature cards, grasp the status of reserved signature cards stored in the safe in real time, accurately grasp the flow of reserved signature cards, and realize the intelligent, scientific and automated management of the safe, RFID technology is used on the basis of traditional safes, and RFID electronic tags are used as information storage media and pasted on the reserved signature cards. RFID readers are installed on the safes, and the electronic tag information is read by the reader to manage the reserved signature cards.
[0005] However, currently only one RFID reader is set in the cell of the safe. The number of electronic tags read by the reader is limited, and it cannot accurately identify multiple reserved signature cards densely placed in the cell, and thus cannot accurately manage the multiple reserved signature cards densely stored. Summary of the Invention
[0006] In order to solve the above problems, the present invention proposes an intelligent cabinet and management method for intensively reading bank reserved signature cards, which realizes accurate information recognition and management of intensive reserved signature cards.
[0007] To achieve the above object, the present invention adopts the following technical solutions:
[0008] Firstly, a smart cabinet for densely reading bank reserved signature cards is proposed, comprising a cabinet body with a plurality of cells arranged on the cabinet body; two readers are arranged in each cell;
[0009] The reader is used to issue an electronic tag query instruction and receive the serial number information of the electronic tag on the bank's reserved signature card in the cell;
[0010] The server is used to manage the bank signature card according to the serial number information obtained by the reader.
[0011] Furthermore, an information collection device is provided on the cabinet;
[0012] An information collection device for obtaining personnel information;
[0013] The server is used to verify the personnel information obtained by the information collection device, and when the verification is passed, the cabinet door of the control cabinet is opened.
[0014] Furthermore, the information collection device is used to obtain facial information and fingerprint information of a person.
[0015] Furthermore, the server is used to control the cabinet door to open when both the facial information and the fingerprint information are verified.
[0016] Furthermore, the cabinet is arranged in multiple layers; each layer includes a plurality of cells, and the cells are used to place a plurality of bank reserved seal cards.
[0017] Furthermore, the two readers in the cell are arranged relative to each other.
[0018] Furthermore, the reader is used to determine the electronic tag that has collided based on the acquired information during the process of receiving the serial number information of the electronic tag in the cell; for the electronic tag that has collided, a binary tree search method is used to determine the serial number information of the electronic tag that has collided.
[0019] Furthermore, the server is also used to obtain the reading failure rate of each serial number information; when the reading failure rate is greater than a set value, a maintenance alarm message is issued.
[0020] Furthermore, the read failure rate = (the number of read failures per unit time / the number of electronic tag query instructions sent by the reader) × 100%.
[0021] Secondly, an intelligent management method for intensively reading bank reserved signature cards is proposed, including:
[0022] Send an electronic tag query instruction through the reader in the cell and receive the serial number information of the electronic tag on the bank reserved signature card in the cell;
[0023] The server manages the bank signature card based on the serial number information obtained by the reader.
[0024] Compared with the prior art, the present invention has the following beneficial effects:
[0025] The present invention proposes an intelligent cabinet and management method for intensively reading bank reserved seal cards. The intelligent cabinet is equipped with two readers in each cell to realize complete reading of the serial number information of all seal cards in the cell. The seal cards are managed based on the read serial number information to prevent the occurrence of the problem of missed reading of seal cards in the cell.
[0026] The management of seal cards includes monitoring seal card problems by generating heat maps, generating personnel-time-serial number three-dimensional operation logs based on the opening and closing of cabinet doors, monitoring the flow of seal cards, and combining the number of times the reader sends electronic tag query instructions with the number of times serial number information is received to obtain the reading failure rate. Based on the reading failure rate, it is determined whether the electronic tag is normal or whether the reader is abnormal to ensure accurate management of seal cards.

[0035] In the absence of conflict, the embodiments of the present invention and the features thereof may be combined with each other.
[0036] Example 1
[0037] In order to achieve effective management of densely reserved signature cards, in this embodiment, a smart cabinet for densely reading bank reserved signature cards is disclosed, such as Figure 1 As shown, it includes a cabinet and a server, and a plurality of cells are set on the cabinet; two readers are set in each cell;
[0038] The reader is used to issue an electronic tag query instruction and receive the serial number information of the electronic tag in the cell;
[0039] The server is used to manage the bank signature card according to the serial number information obtained by the reader.
[0040] like Figure 1 As shown, the cabinet body of the smart cabinet disclosed in this embodiment is arranged in multiple layers; each layer includes multiple cells, and the cells are used to place multiple bank reserved seal cards.
[0041] The two readers in the cell are set opposite to each other.
[0042] Preferably, the reader / writer is an RFID reader / writer.
[0043] The cabinet has 5 layers, each layer has three cells of equal volume, and each cell can densely hold 140 reserved signature cards.
[0044] Each cell is equipped with a dedicated rack for reserved signature cards, which are placed on the rack with the head facing outward and the tail facing inward. Each reserved signature card is also equipped with an RFID tag that stores the card's information. Each card is affixed to the same RFID tag, each with a unique serial number, encoded in binary format. This serial number information can be used to monitor card location in real time (e.g., heat map), track access records (personnel, time, and operation type), and trigger abnormal warnings (e.g., unauthorized operations) based on business rules.
[0045] When the bank's reserved seal cards are stored densely, the RFID reader's antenna is affected by the antenna gain and beam width, and the RFID reader's ability to receive the radio frequency signal emitted by the reader is limited. Therefore, one reader cannot read all 140 reserved seal cards. In order to achieve dense reading of 140 bank's reserved seal cards in each cell, an RFID reader is installed on the left and right sides of each cell, and the RFID reader is installed at the lower center of the left and right sides. Two RFID readers are now used to monitor the bank's reserved seal cards in the cell. This installation position enhances the ability to read the full number of RFID electronic tags; the two RFID readers read the RFID electronic tags on the bank's reserved seal cards in the cell through spatial diversity reception technology.
[0046] By densely placing bank signature cards in a cell, multiple RFID tags are within the reader's range. When multiple tags respond, channel contention, data interference, and aliasing can occur. This embodiment employs an anti-collision strategy to prevent collisions and identify all tags. The multi-tag anti-collision algorithm uses a binary tree search algorithm based on time-division multiple access technology.
[0047] Therefore, the reader / writer of this embodiment is also used to determine the electronic tag that has collided based on the acquired information during the process of receiving the serial number information of the electronic tag in the cell; for the electronic tag that has collided, a binary tree search method is used to determine the serial number information of the electronic tag that has collided.
[0048] The specific process of the reader / writer in this embodiment reading the serial number information of the electronic tag in the cell includes:
[0049] The RFID reader sends an electronic tag query command to the cell through the antenna, asking whether there is an electronic tag and requiring the electronic tag to respond with a unique serial number;
[0050] The RFID electronic tag that meets the conditions in the cell responds, and the reader receives the serial number of the electronic tag through the antenna;
[0051] When multiple tags respond simultaneously in a cell, since the data information transmission channel used by the tag and the reader is the same, there will be multiple copies of data information transmitted in the channel, which may cause channel congestion, resulting in data collision, and the electronic tag cannot be read correctly. Therefore, the reader uses Manchester encoding to determine the collision bit, so as to determine which tags have overlapping responses;
[0052] After the reader determines the tags that collided, it divides the colliding electronic tags into two subsets, left and right 0 and 1, through the binary tree search method. In subset 0, the reader compares the serial numbers of the tags in subset 0 with the corresponding serial numbers in the same digits. If there is no conflict, the identification is correct. If there is a conflict, the reader splits subset 0 into two subsets, 00 and 01. The reader re-outputs the serial number from the highest position 0 where the serial numbers of the tags in subset 0 conflicted, and then compares it with the serial numbers of the tags in subset 00. If there is no conflict, the identification is correct. If there is a conflict, the reader splits subset 0 into two subsets, 000 and 001. The reader re-outputs the serial number from the highest position 0 where the serial numbers of the tags in subset 0 conflicted, and then compares it with the serial numbers of the tags in subset 000. If there is no conflict, the identification is correct. If there is a conflict, the reader splits subset 0 into two subsets, 000 and 001. The reader re-outputs the serial number from the highest position 0 where the serial numbers of the tags in subset 0 conflicted, and then compares it with the serial numbers of the tags in subset 000. If there is a conflict, the identification is correct. If there is a conflict, the reader splits subset 1 again, and so on. This process continues until all tags in subset 0 are identified. The reader then repeats this process to query subset 1. Data operations are then performed on the subset, and the subset enters the "silent" state, responding to query commands sent by the reader.
[0053] After identifying the tag with the smallest serial number, data operations are performed on it and then it enters the "silent" state, and does not respond to the query command sent by the reader.
[0054] During algorithm execution, the reader sends multiple commands to the electronic tags. Each command divides the tags into two groups, and after multiple groupings, a unique tag is finally obtained. During this grouping process, the corresponding command parameters are stored as nodes, resulting in a bifurcated tree of data. Since all these data nodes appear in binary form, it is called a binary tree.
[0055] This embodiment also provides an information collection device on the cabinet;
[0056] An information collection device for obtaining personnel information;
[0057] The server is used to verify the personnel information obtained by the information collection device, and when the verification is passed, the cabinet door of the control cabinet is opened.
[0058] Among them, the information collection device is used to obtain facial information and fingerprint information of people.
[0059] The server is used to control the cabinet door to open when both the face information and the fingerprint information are verified.
[0060] Preferably, the information collection device includes a camera 1 and a fingerprint collection device; the camera 1 is used to obtain facial information of a person; and the fingerprint collection device is used to obtain fingerprint information of a person.
[0061] Only when both the facial information and fingerprint information are verified will the server control the cabinet door to open.
[0062] The information collection device also includes a display screen 3, which is used to display the acquired facial information and fingerprint information; multiple identity authentication improves the security level, solves the risk of card loss and leakage, and solves the information registration of staff receiving seal cards.
[0063] The server is also used to determine the digital archive of the reserved signature card corresponding to each serial number, count all the digital archives of the reserved signature card in each cell, and generate an inventory heat map.
[0064] The server is also used to obtain the reading failure rate of each serial number information; when the reading failure rate is greater than a set value, a maintenance alarm message is issued.
[0065] Among them, the reader periodically issues an electronic tag query instruction. When the reader obtains the serial number information of the electronic tag on the bank's reserved seal card after issuing the electronic tag query instruction, it indicates that the reading is successful; when the reader does not receive the tag response information after issuing the electronic tag query instruction, or the response information cannot be decoded, and the serial number information of the electronic tag on the bank's reserved seal card cannot be obtained, it indicates that the reading has failed.
[0066] The server collects statistics on failures by periodically polling tags.
[0067] Read failure rate = (number of read failures per unit time / number of times the reader sends electronic tag query instructions) × 100%.
[0068] When the read failure rate is greater than the set value, a maintenance alarm message is issued to remind personnel to first check whether the tag is damaged or detached (because it is a consumable part), and then check the signal strength of the reader antenna.
[0069] Specifically, when the reading failure rate exceeds the threshold, the server will issue an "electronic tag abnormality" alarm message and recommend replacing the corresponding tag first; if multiple tags in the same cell fail continuously, the server will issue a "reader maintenance" alarm.
[0070] The server is also used to analyze the access association of cards with different serial numbers based on association rules and identify abnormal operation patterns.
[0071] Association rules refer to analyzing the time, personnel, and combination patterns of seal card access through historical logs, such as card A must be taken out at the same time as card B, and card C and card D cannot be taken out at the same time.
[0072] When seal cards are frequently accessed during non-working hours, an abnormal number of cards are read by a single person within the set time, or the association rules such as "Card A and Card B cannot be taken out at the same time" and "Card C and Card D cannot be taken out at the same time" are violated, the server determines that an abnormal operation has occurred.
[0073] The server is also used to determine that a new reserved signature card is stored in the cell when new serial number information is obtained after the cabinet door is opened, and record the personnel information, opening time and serial number information when the cabinet door is opened; when the cabinet door is opened and the previously obtained serial number information cannot be obtained, it is determined that the reserved signature card corresponding to the serial number information is taken away, and record the personnel information, opening time and serial number information when the cabinet door is opened; and obtain a three-dimensional operation log of personnel, time and serial number.
[0074] The server is also connected to a display screen and a temperature and humidity sensor. The temperature and humidity sensor is used to obtain the temperature and humidity of the office where the smart cabinets are stored; the display screen is used to display the temperature and humidity of the office where the smart cabinets are stored.
[0075] The display screen is also used to display the office address where the smart cabinet is stored, the location of the smart cabinet, and the bank's reserved seal card entry and exit reports.
[0076] Among them, the office address and location of the smart cabinet are preset in the server configuration file, and the bank's reserved seal card entry and exit report is automatically generated by the server based on the seal card operation log.
[0077] In this embodiment, a Forma wheel 4 is further provided at the bottom of the smart cabinet, and the Forma wheel 4 is provided to facilitate the movement of the smart cabinet.
[0078] In addition, the two readers set in each cell of this embodiment can be antennas 2 of the two readers; all reader antennas in the smart cabinet are connected to the reader server, saving cell space and the overall cost of the smart cabinet.

[0082] The server manages the bank signature card based on the serial number information obtained by the reader.
