Description

Technical Field

[0001] This invention relates to the field of warehousing supervision technology, specifically a method for supervising bulk commodity warehousing. Background Technology

[0002] Currently, bulk commodity warehousing supervision still relies primarily on traditional manual methods, which have significant technical shortcomings: First, the accuracy of quantity measurement is low. For bulk commodities such as coal and grain, manual estimation of volume or weighing in multiple batches often results in errors exceeding 10%, and inventory data cannot be updated in real time, easily leading to discrepancies between records and actual inventory. Second, quality monitoring is lagging. The storage environment of bulk commodities directly affects quality, and the long intervals between manual inspections make it difficult to detect problems such as moldy grains and leaks of hazardous chemicals in a timely manner, causing economic losses. Third, safety control is weak. Manual personnel cannot cover the storage area 24 hours a day, resulting in delayed responses to safety risks such as fire prevention, theft prevention, and explosion prevention, which can easily lead to safety accidents. Fourth, data collaboration is poor. Warehousing data is only stored locally and cannot be shared with cargo owners, logistics companies, and financial institutions, forming data silos and hindering the efficiency of supply chain collaboration. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides a method for supervising bulk commodity warehousing, which solves problems such as discrepancies between records and actual inventory, slow response time, high incidence of safety accidents, and repetitive and complex system development.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the present invention provides the following technical solution: a method for supervising bulk commodity warehousing, comprising the following steps: S1: Multi-dimensional data collection. Data collection equipment is configured according to the type of bulk commodity to collect commodity quantity data, environmental data, safety protection data, and circulation information. S2: Data preprocessing. Noise reduction, calibration, and stitching are performed on the collected raw data. S3: Data calculation and analysis. The actual weight or volume of the commodity is calculated based on the preprocessed data. S4: Real-time monitoring and early warning. Commodity inventory, environmental, and safety status are displayed on the monitoring terminal. S5: Execution control and information management. Automatic control equipment is connected to execute control commands.

[0007] Preferably, for bulk commodities, lidar is used to collect point cloud data from at least two angles, and for canned goods, a level gauge combined with a pressure sensor is used to collect data.

[0008] Preferably, in step S2, a bilateral filtering algorithm is used to remove point cloud noise, and multi-angle point cloud data is stitched together by an iterative nearest point algorithm; mean filtering is used to calibrate the environmental sensor data.

[0009] Preferably, in step S3, the actual weight of the product is calculated by combining the volume of the three-dimensional model with the density correction coefficient. The density correction coefficient is retrieved from a preset coefficient table based on the product type, temperature and humidity, and stacking height. The quality change trend is predicted using an LSTM model, and the input parameters include historical environmental data and product characteristic parameters.

[0010] Preferably, in step S4, the warning threshold is set differently according to the commodity type. The humidity warning threshold for grain storage is 70-75%, and the gas concentration warning threshold for hazardous chemical storage is 0.05-0.1%. The alarm channels include audible and visual alarms, SMS push and APP notification.

[0011] Preferably, in step S5, the data can be manually triggered by the monitoring terminal or automatically triggered by the system; data sharing adopts hierarchical management of permissions, allowing cargo owners to query inventory data and regulatory agencies to query all data.

Quantity data includes LiDAR 3D point cloud data, weighing sensor weight data, or liquid level gauge liquid level data. Environmental data includes temperature, humidity, and gas concentration data. S2: Data preprocessing. The collected raw data is denoised, calibrated, and stitched together. Different types of data are associated with unique commodity identifiers and collection times to construct a structured dataset. All data is stored as a sequence of "grain warehouse number + grain variety - time". S3: Data calculation and analysis. Based on the preprocessed data, the actual weight or volume of the commodity is calculated. Algorithms are used to analyze the correlation between environmental data and commodity quality to predict quality change trends. S4: Real-time monitoring and early warning. The monitoring terminal displays commodity inventory, environmental, and safety status. When data exceeds preset thresholds, multi-channel alarms are triggered, and anomaly handling suggestions are generated. S5: Execution control and information management. The system connects to automatic control equipment to execute control commands, records all regulatory data, and generates ledgers. It supports data sharing among multiple entities. Cargo owners can query real-time inventory and historical data via an app without on-site verification.

[0019] For bulk commodities, lidar is used to collect point cloud data from at least two angles. For canned goods, a level gauge combined with a pressure sensor is used to collect data. The data collection frequency is 10-30 minutes per time.

[0020] In step S2, a bilateral filtering algorithm is used to remove point cloud noise, and multi-angle point cloud data is stitched together by an iterative nearest point algorithm; mean filtering is used to calibrate the environmental sensor data, with a calibration cycle of 24 hours / time.

[0021] In step S3, the actual weight of the goods is calculated by combining the volume of the three-dimensional model with the density correction coefficient. The density correction coefficient is retrieved from the preset coefficient table based on the type of goods, temperature and humidity, and stacking height. The trend of quality change is predicted using an LSTM model, and the input parameters include historical environmental data and goods characteristic parameters.

[0022] In step S4, the warning thresholds are set differently according to the commodity type. The humidity warning threshold for grain storage is 70-75%, and the gas concentration warning threshold for hazardous chemical storage is 0.05-0.1%. The alarm channels include audible and visual alarms, SMS push and APP notifications.

[0023] In step S5, it can be triggered manually through the monitoring terminal or automatically by the system; data sharing adopts hierarchical management of permissions, and cargo owners can query inventory data, while regulatory agencies can query the full data.
