Description

Technical Field

[0001] The present application relates to the field of logistics information technology, and in particular to a shared pallet management method and system. Background Art

[0002] Within manufacturing companies, shared pallets can be used for the handling and storage of raw materials and parts, facilitating material distribution and management of production lines. If there are upstream and downstream relationships between different companies in the industrial chain, they can also share pallets to achieve seamless flow of raw materials from suppliers to manufacturing companies. The use of shared pallets in warehouses facilitates the stacking, storage and inventory of goods, improving warehouse space utilization. At the same time, when goods are transferred between different warehouses, shared pallets can flow with the goods, reducing the exchange of goods between different pallets and improving warehousing operation efficiency. In road, rail, water and other modes of transportation, shared pallets can be used as a carrier for goods, facilitating the loading and unloading and transportation of goods. For example, in container transportation, placing goods on shared pallets and then loading them into containers can improve the space utilization of containers and the stability of goods. Logistics shared pallets are of great significance to promoting the standardization, informatization and green development of the logistics industry, and are one of the important trends in the development of modern logistics; Among them, the shared pallet management method realizes the automated management of pallets in logistics and supply chains by integrating wireless radio frequency identification (RFID) technology, improving the efficiency of cargo transportation, storage and turnover; the system can not only track the location and status of pallets and the materials they carry in real time, but also support cross-enterprise and multi-user resource sharing and collaborative work, thereby significantly reducing operating costs and enhancing transparency; however, the current application of this technology also faces challenges: first, in scenarios with materials of different sizes and stacking heights, how to stably read and write RFID tag information becomes a key issue, because too long or too short a reading and writing distance will affect the accuracy of information recognition; secondly, it is about system security. Especially when multiple entities use it together, it becomes crucial to ensure the security of pallets and related data; Therefore, it is necessary to dynamically adjust the reading and writing distance of RFID tags according to the application scenarios to ensure the stability of information recognition, and to ensure the security of pallet data by formulating reasonable access permission management and improving encryption levels. Summary of the invention

[0003] In view of this, an embodiment of the present disclosure provides a shared tray management method and system, which at least partially solve the problems existing in the prior art.

[0006] Preferably, receive the first login request from the user end and verify whether the identity identification information of the account matches the system record; Preferably, if it does not match, directly reject the request; If it is a legal user, further judge the activity frequency F_user of the user. If F_user <= F_threshold, trigger a higher-level security verification mechanism, otherwise maintain the conventional permission mode; Preferably, use the hash algorithm to generate a temporary session key K_temporary and send it to the front end as one of the encryption tools for the next communication; if the detection time interval Δt > δ_timeout, that is, exceeding the timeout parameter, immediately invalidate the current session key.

[0007] Preferably, dynamically evaluate the risk level Risk_level of the operation behavior.

[0012] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

It should be apparent that the aspects described herein may be embodied in a wide variety of forms, and any specific structure and / or function described herein is merely illustrative. Based on the present disclosure, it should be understood by those skilled in the art that an aspect described herein may be implemented independently of any other aspect, and two or more of these aspects may be combined in various ways. For example, any number of aspects described herein may be used to implement the device and / or practice the method. In addition, other structures and / or functionalities other than one or more of the aspects described herein may be used to implement this device and / or practice this method.

[0015] It should also be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present disclosure. The drawings only show components related to the present disclosure rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0016] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the aspects described may be practiced without these specific details.

[0017] Next, referring to the accompanying drawings, a shared pallet management method of the present invention is described, wherein the system and method include four core steps: first, dynamically adjusting the transmission power through the intelligent reader to optimize the reading and writing distance, solving the stability problem of information recognition under different material sizes and stacking heights; second, evaluating and allocating different levels of encryption levels and permission settings in real time based on system access requests to ensure the security of pallet data; third, collecting and recording the RFID tag information on the pallet to the cloud database for data management, which is convenient for subsequent query and management; finally, monitoring the system operation status and feeding back adjustment instructions to ensure continuous and stable pallet data processing; The following describes in detail how each step works and what it does: The process of dynamically adjusting the transmission power according to the material size and stacking height to optimize the reading and writing distance through the smart reader is as follows; the smart reader is pre-set with multiple different transmission power gears. When it detects that different types of materials or changes in the height of the pallet stacking are detected, it can select the optimal power gear through the built-in sensor or preset parameters; for example, in one embodiment, if the reader finds that the current object to be identified is a high-stacked pallet, it will increase the power to ensure that it can effectively penetrate multiple layers of materials for data exchange; on the contrary, if it is a small flat panel used for a single piece of low-thickness goods, only a lower energy level is required to accurately capture the information, and this can reduce interference with the external environment and possible energy waste; this dynamic adaptation strategy helps to overcome the limitations of the reading range caused by the different shapes of objects, while also maintaining appropriate signal strength to avoid unnecessary energy consumption increases or reduced performance; more importantly, this method greatly improves the stability of information recognition in various scenarios and improves the overall efficiency of the system.

[0018] To enhance data security, the system regulates access rights and encryption measures. When receiving external access attempts, the solution will quickly determine the appropriate access level based on the user's identity level, and enable a variety of protection measures ranging from basic identity authentication to top-level end-to-end confidentiality protection. Specifically, whenever a newly added node attempts to obtain data associated with one or more RFID tags, the central server will immediately verify what specific functions this entity has - read-only permissions, add and delete rights, or full control, and choose whether to open the corresponding database content based on this conclusion. In addition, considering that more sensitive files within the enterprise require stricter storage conditions and preventive measures, a high-level coding locking function will be added to this important information, so that even if it is stolen without authorization, the true meaning cannot be interpreted to prevent confidential information from being leaked.

[0019] The collection and recording process is achieved by numerous miniature code-reading devices installed around the storage area or on the ends of handling equipment. These small machines continuously scan the electromagnetic frequency bands in the nearby space to search for target objects with electronic identifiers. Once the correct channel is encountered, they immediately begin to collect all necessary parameter information and upload it to the rear storage center via wireless transmission. A huge cloud platform built with a complete set of high-performance computing clusters is used here to accumulate and classify a series of rich content behind each chip, such as timestamp marks, product category codes, and transportation flow records. With the effective combination of the computing advantages brought by this large-scale distributed architecture and efficient network communication technology, administrators can not only instantly review historical order details to trace the flow of goods, but also realize refined supervision of the circulation of large quantities of physical assets, providing strong data support for corporate decision-making.

[0020] The last part is to closely track and monitor the status of the entire operating environment, and be ready to issue guidance and improvement suggestions to the front-end operation module at any time, so as to ensure the key to smooth and reliable operation of each link; on the one hand, a strict information feedback network is formed by using several dedicated monitoring hosts distributed between the nodes of the network to continuously collect various operating indicators such as power supply conditions, temperature and humidity trends, physical location change prompts, etc. around the clock, and through intelligent analysis algorithm models, real-time diagnosis and evaluation are carried out to find out the existing weak links or potential threat factors and issue early warnings; on the other hand, based on the knowledge accumulation and experience accumulation that has been established previously, combined with the current actual production operation progress requirements, a series of scientific, reasonable and effective adjustment instructions are formulated in a targeted manner and passed to the corresponding execution units for application and improvement, so that each component can always maintain the most ideal state and be put into the task; doing so can not only promptly correct possible risks and hidden dangers to avoid accidents, but also greatly extend the service life of related mechanical equipment and improve the overall benefits.

[0021] Through the design innovations in the above aspects, a shared pallet management method successfully solves the information exchange difficulties and insufficient information security problems often encountered in the traditional management model; in particular, the dynamic adjustment method adopted to deal with the diversity of material sizes and stacking differences greatly enhances the probability of effective label reading, while ensuring efficient logistics operation and strict protection of business secrets; and the flexible permission configuration in the access control mechanism further enhances the advantages of system flexibility and maintainability, which is convenient for daily operation management and can well meet the special needs of special periods; it can be said that this achievement has important promotion value and development potential for the modern logistics industry.

[0022] Next, an exemplary construction process of the present invention is described: In the first step, the intelligent reader dynamically adjusts the transmission power. For example, in the RFID-based pallet sharing management system and method, the system calculates the basic transmission power Ptx. Specifically, the formula is Ptx=α*(D^2), where α is a power constant (e.g., 0.5 to 1), and D represents the estimated distance from the pallet to the reader in meters, usually ranging from 0 to 30 meters. The optimal value depends on the environment and signal attenuation. The material size sensor obtains the maximum length Lmax and width Wmax of the current detection object on the pallet. If the product of Lmax and Wmax is greater than a certain threshold γ_0, the compensation factor κ is applied to adjust the gain to the final transmission power. power value; here γ_0 represents the value of the allowed load size limit, and the default value is set to 0.75m² or greater; H represents the height of the load weight stacked on the pallet; when H does not exceed a specific threshold h_threshold, the default configuration is used for output power setting; on the contrary, when the height exceeds this standard, the power reduction correction formula, P=Ptx / ln(H / h_min+1) is used to adapt to higher stacks. The logic of this formula is to reasonably control energy loss while considering safety and prevent signal interference, thereby improving data transmission stability and ensuring efficient operation of the system; at the same time, ensure that the settings of h_threshold and h_min are both safe and can effectively reduce energy waste.

[0023] The second important part is the implementation of management verification and protection measures for the user's initial access request: including details such as identity confirmation, frequency assessment and application of encryption strategies. Specifically, when the user device initiates the initial registration or login behavior, the system receives the login request and performs a matching verification task on the account information. If there is no match, an exception feedback will be immediately returned to reject the request operation. If the verification is correct, the user activity index will be checked. For example, if the number of logins within a month is less than a certain threshold F_user, it will be marked as a need to strengthen the security audit mechanism to prevent hackers from illegally attempting to log in. Here, it is recommended that the F_threshold value be set to a normal access record of more than once a week to reduce the risk of being attacked. After successfully passing the above process, the server uses the hash algorithm to produce a string of irreversible transformations, and the new password is only valid for this session cycle as a security guarantee for the front-end and back-end information interaction. If the monitoring timeout parameter Δt exceeds the default δ_timeout, the abandonment instruction will be triggered to ensure the real-time and reliable communication link. In addition, there is a deep monitoring and analysis of the user's operation behavior pattern to determine whether it belongs to the category of malicious threats. Once the detection result reaches the predetermined risk limit R_max, action will be taken to directly block the corresponding account to prevent all possible sources of harm from having actual impact.

[0024] A shared pallet management method of the present invention includes: a series of coordinated steps, aiming to achieve stable information identification of pallets and their loaded materials in different scenarios and a safe and efficient management system and operation method through RFID (radio frequency identification) technology.

[0025] The overall process mainly covers the following aspects: Intelligent dynamic transmit power adjustment: First, at system startup or when new material pallets are detected entering or leaving the warehouse, the system's central control processor sends instructions to the smart readers distributed on site; each reader can receive this instruction and make a pre-judgment and evaluation of the pallet size and height information of the load to be measured; the data is measured through an embedded sensor network or other means, and the appropriate output energy level is determined based on the built-in empirical model database or self-learning algorithm, that is, the most appropriate wireless signal transmission strength for individual occasions is adjusted to ensure that the electronic tags attached to the surface of objects of various shapes and sizes are effective and their data can be identified without interference without manual adjustment of parameter settings; such intelligent adjustment measures effectively improve the accuracy and coverage of RFID information reading under complex environmental conditions, and solve the technical problem of ensuring that all tags are captured normally in the face of extremely different cargo sizes and stacking conditions.

[0026] Real-time security policy enforcement mechanism: As more and more companies pay attention to the security management of internal data, our system will quickly analyze the identity authentication results of the source of the access request when it arrives, and determine the corresponding access permission level and encryption method selection strategy based on the specific application scenario requirements.

[0027] -For low-sensitivity operations, the system uses a simpler and lighter authentication protocol that still has basic security features, such as only allowing reading of non-confidential information in the public domain without opening up editing functions.

[0028] -For high-risk transactions such as updating the detailed list of certain batches of specific products in the warehouse, high-strength encryption algorithms such as elliptic curve cryptography (ECC) are used, combined with strict two-step confirmation or multi-factor authentication (MFA), and detailed permission segmentation restrictions to ensure that every change is fully authorized.

[0029] In addition, all permission settings and encryption and decryption operations are traceable throughout the process, providing evidence chain support for subsequent review, fundamentally enhancing the construction of a system to ensure the authenticity and non-tamperability of each data flow in the company's logistics and transportation links.

[0030] In summary: the present invention realizes reliable communication connection under different material property conditions through the above steps, and especially provides an answer to the problem of optimizing the reading distance of RFID tags; and through reasonable identity identification of visitors at all levels and appropriate security policy deployment, it meets the risk prevention and control requirements of protecting key supply chain intelligence from unauthorized access or destruction in a modern business environment; the system can not only ensure the stability of information transmission and maximize processing efficiency, but also greatly improve the warehouse operation efficiency and service quality level, becoming one of the indispensable components of modern logistics enterprises.

[0031] A shared pallet management system, the system comprising: Data reading and writing module, used to dynamically adjust the transmission power according to the material size and stacking height to optimize the reading and writing distance of the material; Access data assessment module, which is used to conduct real-time assessment based on access requests and assign different levels of encryption and permission settings; Data collection and management module, used to collect and record the RFID tag information on the pallet to the cloud database to facilitate data management of the pallet; The system monitoring module is used to monitor the status of system operation and provide feedback of adjustment instructions to ensure continuous and stable processing of pallet data.

[0032] With the completion of the identity confirmation process, each pallet that has passed the identification will have its own identification in the system and begin to establish all dynamic information related to it - these information flows covering the entire chain from the initial state to the end constitute a complete historical record system; any changes thereafter will be accurately captured and transmitted to the central monitoring platform in real time, allowing managers to clearly grasp every subtle movement in the logistics and achieve continuous status tracking.

[0033] In addition, the system design also includes an important intelligent function - that is, based on the real-time collected data, the pre-programmed algorithm is used for in-depth analysis and processing, that is, timely inspections are initiated for places where abnormal situations may occur and the corresponding early warning mechanism is triggered; the key point involved here is how to set and optimize the strategy for abnormal event detection; through the accumulation of a large number of case studies, the understanding and modeling of different types of potential threat patterns, the detection algorithm is continuously improved to make it more sensitive, accurate and reliable, so that it can quickly identify whether illegal use or packet loss has occurred; if the monitoring results exceed the normal range, they will be immediately executed according to the pre-set response measures, in order to eliminate safety hazards or recover lost items as soon as possible, and minimize the risk of loss.

[0034] In summary, the present invention not only ensures information security, but also improves the operating efficiency of the management system, enhances supply chain transparency, and reduces costs; the above steps form a closed-loop management system to ensure the safety, efficiency, and traceability of cargo transportation.
