Abstract
Description
Technical Field
[0001] This invention relates to the field of intelligent warehousing and logistics technology, and in particular to a three-dimensional warehousing system and method for use in breathing mask filter modules. Background Technology
[0002] Respiratory mask filter modules are key consumables in medical and industrial protective equipment, characterized by numerous specifications and models, strict batch management, and demanding storage environment requirements. Currently, the following technical challenges exist in storing these supplies: Insufficient pollution control: Traditional shelves have an open structure, which cannot effectively isolate pollutants such as dust and moisture, affecting the protective performance and safety of the filter module.
[0003] Batch management is difficult: the filtering module has strict expiration date management and traceability requirements. Traditional warehouses rely on manual records, which can easily lead to batch confusion and inaccurate first-in-first-out execution.
[0004] Low space utilization: Filter modules are small in size and light in weight but numerous in number, resulting in low storage density on traditional shelves and difficulty in achieving high-precision positioning and rapid picking.
[0005] Lack of transparency in inventory status: It is impossible to accurately grasp the inventory quantity, location status, and storage duration of each model of filter module in real time, which affects material allocation decisions.
[0006] In the prior art, Chinese patent with publication number CN112224648A proposes a UWB-based positioning system for automated warehouses, but it does not consider the special protection requirements of medical supplies; Chinese patent with publication number CN113443416B uses visual recognition technology for location management, but the open storage environment cannot meet the cleanliness requirements of the filtration module.
[0007] Therefore, there is an urgent need in this field for a specialized warehousing solution that can provide a clean storage environment for respirator filter modules, and enable precise batch management and rapid intelligent access. Summary of the Invention
[0008] The technical problem this invention aims to solve is that current automated storage systems cannot provide a clean storage environment for respirator filter modules, and therefore cannot achieve precise batch management and rapid intelligent storage and retrieval.

[0012] The environmental monitoring unit includes: a temperature and humidity sensor with an accuracy of ±0.5℃ and ±3%RH; a laser particulate matter sensor with a detection accuracy of 0.3μm; and a data recording module with a storage capacity of 32MB.
[0013] The environmental protection system includes: a HEPA high-efficiency filter unit with a filtration efficiency of 99.97%; a constant temperature and humidity device with a control accuracy of ±1℃ and ±5%RH; and a positive pressure maintenance system with a pressure control range of 5-15Pa.
[0014] The intelligent control system is configured to: automatically allocate storage locations based on the filter module type and expiration date; automatically generate picking lists according to the first-in-first-out principle; and provide real-time warnings of abnormal environmental parameters and near-expiration inventory.
[0015] A system-based warehouse management method for filtering modules includes the following steps: scanning filtering module information, generating a unique identifier and allocating storage locations; using a robotic arm to pick up the module and store it in a sealed warehouse, recording environmental parameters; monitoring the status of each storage location in real time and generating inventory reports periodically; retrieving the target module according to the first-in-first-out principle and performing a quality check before it leaves the warehouse.
[0016] The allocation of storage locations includes: allocating different levels of storage locations according to the validity period of the filtering modules; storing modules of the same batch centrally but dispersed in different storage locations; and allocating high-frequency access modules to storage locations near the exit.
[0017] The allocation of storage locations also includes quality traceability steps: recording the inbound time, storage location, and environmental parameters of each module; tracking the outbound time and issuing department of each module; and generating a complete quality traceability report.
[0018] The allocation of storage locations also includes early warning management steps: issuing real-time alarms when environmental parameters exceed the set range; providing early warnings of inventory nearing expiration 30 days in advance; and automatically generating replenishment suggestions when inventory levels fall below the safety stock level.
[0019] The present invention has the following significant advantages: Clean and reliable storage environment: Through the sealed chamber design and environmental control system, the filter module is ensured to remain uncontaminated throughout the entire storage cycle, and its protective performance is effectively maintained; Significantly improved storage density: The three-dimensional design increases space utilization to over 85%, resulting in 3-5 times more storage capacity for the same floor space; Significantly improved management accuracy: Through RFID and intelligent control systems, batch management accuracy is 100% and first-in-first-out execution rate is 100%; Rapid and efficient emergency response: The automated storage and retrieval system reduces the average inbound and outbound time to less than 2 minutes, supporting rapid material allocation in case of emergencies; Complete and reliable quality traceability: Establish a digital archive for the entire process from warehousing to outbound, providing complete data support for quality management and problem traceability.
