Description

Technical Field

[0001] The present invention relates to the technical field of Internet of Things and bulk commodity management, and specifically to a digital intelligent labeling and management system for bulk commodity property rights based on the Internet of Things. Background Art

[0002] The property rights management of bulk commodities such as coal has long faced the problem of a disconnect between the dynamic changes in physical properties and the real-time quantification of commercial value. In the traditional supply chain, coal, as a bulk commodity, relies on manual records and static labels for its property rights marking, which cannot track the impact of the storage environment on the quality of the goods in real time. In particular, in scenarios where coal oxidation causes the calorific value to decay, there is a significant deviation between the property rights status and the actual value of the goods, resulting in a lack of transparency in transaction pricing.

[0003] Currently, existing technologies related to coal storage management have obvious shortcomings. For example, announcement number CN201711434049 provides a bulk commodity supply chain IoT management system based on smart pallets. It tracks the location and logistics status of goods through smart pallets, but does not solve the problem of the dynamic correlation between coal oxidation rate and property value. Its sensors only monitor location and basic temperature and humidity, and lack multi-dimensional parameter fusion analysis such as stack pressure and dielectric constant, resulting in insufficient oxidation prediction accuracy. A quantitative correlation between oxidation rate and property shelf life has not been established, and the residual value of coal cannot be dynamically predicted. This dynamic price adjustment without combining the status of the commodity itself makes it difficult to reflect value fluctuations caused by changes in shelf life. The lack of shelf life prediction leads to data silos and decision-making lags in property management.

[0004] In summary, existing technologies have significant defects in the multi-parameter linkage analysis of coal storage environment and the dynamic pricing mechanism based on commodity status. There is an urgent need for an intelligent system that can integrate environmental parameter monitoring, accurately predict shelf life, dynamically adjust transaction prices, and realize the full life cycle management of property rights to solve the efficiency and benefit bottlenecks in the coal industry in the storage and trading links.

This process enables the quality changes of coal during storage to be captured in time and converted into property information, optimize inventory management, and the transaction management module provides fair pricing references for both parties to the transaction based on real-time property information and dynamic pricing mechanisms, accelerates the transaction process, reduces transaction disputes caused by information lags, shortens the coal turnover cycle, and significantly improves storage space utilization and enterprise turnover efficiency.

[0019] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0020] Example 1

[0021] This embodiment demonstrates the working principle and system composition of a digital intelligent labeling management system for bulk commodity property rights based on the Internet of Things. Figure 2 As shown in the figure, the system integrates the environmental parameter monitoring module, oxidation rate calculation module, property right labeling module, dynamic pricing decision module and transaction management module to build a digital management system for the entire process from coal storage environmental parameter collection to property right transaction. The system adopts multi-sensor collaborative monitoring technology to obtain storage environment data in real time, uses oxidation rate calculation and predicts the shelf life of coal, and adjusts the transaction price dynamically according to market supply and demand, ultimately realizing intelligent labeling and efficient management of property rights.

[0022] The environmental parameter monitoring module is used to monitor the environmental parameters of temperature, humidity, and stack pressure data in the storage area in real time, and transmit these data to the oxidation rate calculation module. The module includes a sensor array unit, a data processing unit, and a data transmission unit. The sensor array unit is deployed at different locations in the coal storage area. The temperature and humidity sensors can collect temperature data and relative humidity data of the storage environment in real time. The stack pressure sensor uses a piezoresistive thin film sensor, which is attached to the stress point of the coal stack to monitor the stack pressure strength. The sensor array is deployed in a distributed manner to cover the temperature gradient, humidity difference and stack pressure distribution of the storage area, ensuring the spatial representativeness of the collected data to capture the differences in environmental parameters at different heights and locations. The data processing unit is used to perform signal conversion and preprocessing of sensor data. The physical quantities collected by the sensors are converted into signals through the data processing unit. That is, the digital signals of the temperature and humidity sensors are directly transmitted to the processing unit, and the analog voltage signal of the stack pressure sensor is converted into a digital signal. At the same time, the stack pressure signal is amplified, and the raw temperature and humidity data are converted into standard physical quantities. The stack pressure data is converted into pressure values. The data accuracy is ensured through regular calibration. The data transmission unit integrates and distributes the processed environmental parameter data, and packages the data and sends it to the oxidation rate calculation module to form environmental parameter data based on time series.

[0023] After receiving the environmental parameters of temperature, humidity and pile pressure data from the environmental parameter monitoring module, the oxidation rate calculation module calculates the oxidation rate of coal in the current storage environment according to the coal oxidation rate algorithm and sends the calculation result to the property rights marking module. This module includes a data receiving unit and an oxidation rate calculation unit; The data receiving unit acquires the temperature data transmitted by the environmental parameter monitoring module in real time. , humidity data and compressive strength data , and preprocessing; The oxidation rate calculation unit performs in-depth processing on the environmental parameter data transmitted by the data receiving unit to calculate the oxidation rate of coal under the current storage environment. Oxidation rate at time , which is used to reflect the quantitative relationship between coal oxidation rate and storage environment parameters. , in the coal oxidation reaction, represents the exponential effect of temperature on the reaction rate, is the pre-oxidation coefficient, which is a benchmark value obtained by fitting the initial oxidation rate of coal samples under a standard environment of temperature 25°C and humidity 60% RH, ranging from 0.05 to 0.2. is the activation energy, which represents the minimum energy required for the coal oxidation reaction to occur and has a default value of 82.3 kJ / mol. is the ideal gas constant, which is used to establish a quantitative relationship between temperature and reaction rate and has a default value of 8.314. and are temperature and humidity data respectively, is the humidity impact factor, which is used to quantify the effect of humidity on the oxidation rate and has a default value of 0.017. is the pile compressive strength data, It is the base pressure, which is set as the coal safe storage pressure threshold of 0.5MPa. Is the pressure influence factor, which is used to indicate the sensitivity of the change of stack pressure strength to the oxidation rate. The default value is 0.18, and the calculated oxidation rate The calculation results are sent to the property rights marking module in real time and stored in the database.

[0024] The property rights marking module, through the linkage between the shelf life calculation unit and the inventory prioritization unit, transforms the physical process of coal oxidation into quantifiable and actionable property rights status information, achieving an upgrade from goods management to value management. After receiving the oxidation rate data from the oxidation rate calculation module, the property rights marking module combines the preset coal shelf life standards to dynamically calculate and display the remaining shelf life of each batch of coal. At the same time, it automatically prioritizes inventory based on the remaining shelf life and stores the marking information in the database. Among them, the shelf life calculation unit converts the dynamic physical parameter of oxidation rate into the remaining shelf life, providing a time dimension decision basis for inventory management, and obtains the real-time oxidation rate from the oxidation rate calculation module. , retrieve the initial quality record of coal storage from the transaction management module database and volume , calculate and determine the remaining shelf life of each batch of coal , Indicates the remaining shelf life, that is, from the current moment The remaining time that the coal can maintain the state of meeting the quality standards under the current storage environment, The initial quality of coal, that is, the quality of coal when it enters the warehouse. This data is recorded when the coal enters the warehouse and stored in the database. is the oxidation rate, The volume of coal is measured when the coal is put into storage and recorded in the database. It is the correction coefficient, with a value range of 0.8-1.2, which reflects the impact of environmental changes on quality in real time; The inventory prioritization unit uses the remaining shelf life calculated by the shelf life calculation unit , automatically divide the inventory priority according to the preset division rules, give priority to the coal that is close to the shelf life, the division rules of the inventory priority division unit are: when When the coal is stored normally, it is classified as Class A, which means that the coal has sufficient shelf life. The safety stock threshold indicates the lower limit of the remaining time for the coal quality to remain within the standard range under the current storage environment. The default value is the initial shelf life. 60%~80%; when When the coal is in the batch, it is classified as Class B, prompting attention to the status of the batch of coal and timely arrangement of shipment. The emergency processing threshold indicates the time point when the coal is about to be forced out of the warehouse due to quality failure. The default value is the initial shelf life. 10%~20%; when When the coal reaches the expiration date, it is classified as Class C, indicating that the batch of coal is approaching its shelf life and is immediately scheduled for shipment. The system automatically includes the batch in the candidate list for weekly shipment plan to avoid total loss due to expiration. This grading mechanism not only achieves refined inventory management, but also ensures real-time synchronization of storage strategies with the actual status of coal through dynamic adjustments, and intuitively prompts operators to take corresponding measures, thereby significantly improving inventory turnover efficiency and reducing quality risks.

[0025] The dynamic pricing decision module, through the collaborative operation of the market data collection unit and the pricing algorithm processing unit, constructs a real-time pricing function that integrates the physical state of the commodity with market dynamics. It obtains real-time updated remaining shelf life and inventory priority information from the property rights labeling module, and combines it with market supply and demand data to construct a dynamic coal price adjustment algorithm. This algorithm can calculate the corresponding discount ratio for coal with different remaining shelf life, and then generate a real-time transaction guidance price. The market data collection unit connects to the industry data platform, enterprise procurement system and price monitoring platform through the data interface to obtain the total supply of the coal market in real time Total demand , regional supply distribution, proportion of different coal types and other structured data, while capturing 24-hour price volatility In order to more accurately reflect the actual situation of market supply and demand, this unit introduces a price fluctuation sensitivity coefficient. (0.1-0.3), through the formula Calculate the market supply and demand index to take into account speculative demand or supply adjustments caused by price fluctuations, and avoid pricing deviations caused by relying solely on the supply and demand quantity ratio. The pricing algorithm processing unit is based on the market supply and demand index and combines the remaining shelf life output by the property rights marking module. Generate real-time transaction guidance price through multi-dimensional parameter linkage with inventory priority , ,in, The shelf life attenuation coefficient ranges from 0.6 to 0.9, which reflects the strong correlation between shelf life and price. The shorter the remaining shelf life, the greater the price discount, and through the square term It amplifies the price decay rate when the shelf life is approaching. is the supply and demand adjustment factor, ranging from 0.2 to 0.5. The setting enables the market supply and demand relationship to be transmitted to the price system in real time, for example, when supply exceeds demand ( ), the price can rise in proportion to the supply and demand index, and vice versa. is the oxidation risk correction term, which takes the oxidation activity of coal itself (pre-oxidation coefficient Combined with market supply and demand factors, the potential loss premium is automatically deducted when pricing coal with high oxidation risk, further improving the scientific nature of pricing. Through this pricing formula, the system can generate differentiated real-time guidance prices for the specific status of different batches of coal (such as remaining shelf life, inventory priority) and market environment. For example, for coal that is approaching its shelf life but is in tight market demand, the system will automatically balance the shelf life discount and the supply and demand premium to avoid pricing distortion caused by relying solely on a single dimension, thereby providing both parties to the transaction with a fairer decision-making basis, reducing the blindness of price negotiations and improving the success rate of transactions.

[0026] The transaction management module, as the terminal execution layer of the system, integrates the price output unit, transaction request receiving unit, transaction auxiliary processing unit and blockchain database, realizing the automated management of the entire process from transaction intention receipt to property rights change; Among them, the price output unit will generate the real-time guidance price generated by the dynamic pricing model according to the inventory priority and the remaining shelf life. Further refined into a three-level price system: A-level price The purpose is to encourage buyers to give priority to high-shelf-life coal through premium prices, while increasing the return on enterprises' high-quality inventory. As a benchmark price, it applies to the normal circulation of stock batches to ensure that the price is in line with the market average. Through the slow-selling penalty mechanism The default value is 0.5. The system (the number of days unsold) forces the rapid turnover of coal nearing its expiration date. For example, once coal reaches Grade C, the price automatically decreases by 5% for every day it remains unsold until the minimum price is triggered or the transaction is completed, effectively avoiding the risk of value loss due to inventory backlogs. The transaction request receiving unit is responsible for reviewing and filtering the transaction entry. It performs multiple checks on the received transaction intention, coal batch, transaction quantity and other information. First, it verifies the data conforms to the system protocol specifications through format verification. Secondly, it verifies the batch property status by accessing the blockchain database through integrity check. At the same time, it cooperates with the market data collection unit to match the current inventory quantity with the market supply and demand situation in real time. Requests that exceed the tradable quantity or have title defects will be automatically rejected and the reasons will be fed back. This process not only ensures the feasibility of the transaction, but also reduces invalid operations in the subsequent process through pre-audit, thereby improving the overall transaction efficiency. The transaction support processing unit uses intelligent means to facilitate the completion of closed-loop transactions, including intelligent matching, evidence storage, property rights changes, and data traceability. During intelligent matching, the system automatically matches potential counterparties based on a three-tiered pricing system and the bid ranges of both parties, reducing the time and cost of manual negotiation. Once a transaction is concluded, the database immediately records key data such as transaction time, quantity, price, and the identities of both parties, generates a unique transaction number, and synchronizes the property rights change information to the property rights annotation module, enabling real-time transfer of ownership. This module encrypts information throughout the entire process, including environmental parameter data, oxidation rate calculations, and inventory priority change records, creating an unalterable audit trail. In the event of a transaction dispute or quality traceability requirement, users can retrieve all key node data from coal receipt to transaction completion by transaction number or batch number. Furthermore, for Grade C coal, the system automatically triggers a rapid outbound delivery mechanism. Combined with the intelligent scheduling capabilities of the warehouse management system, this ensures that high-risk inventory can be physically delivered in the shortest possible time, further reducing the risk of oxidation losses. The transaction support processing unit enables fully digital operations from price generation, transaction matching, to property rights delivery, significantly improving transaction transparency and execution efficiency.

[0027] In summary, this embodiment is a digital intelligent labeling management system for commodity property rights based on the Internet of Things. The modules are interconnected to form a full life cycle management link of environmental monitoring-quality assessment-pricing decision-transaction execution. The temperature, humidity and stack pressure data collected by the environmental parameter monitoring module at a frequency of minutes are pre-processed and pushed to the oxidation rate calculation module in real time through the message queue. After completing the physical calculation, the latter immediately transmits the oxidation rate result to the property right labeling module. The property right labeling module generates shelf life and inventory priority information based on the basic data, and synchronizes it to the dynamic pricing decision module. The real-time guidance price output by the dynamic pricing decision module and the execution data of the transaction management module are fed back to the front-end monitoring and evaluation link, forming a data-driven management optimization cycle. This high-frequency data interaction ensures the system's timely response to changes in the storage environment and market dynamics, thereby avoiding the risk of lag.
