A method for full lifecycle management and multi-level access control of acid-regenerated iron oxide powder

Abstract

This invention discloses a method for full lifecycle management and multi-level access control of acid-regenerated iron oxide powder. Through unique batch identification, status-driven processes, IP whitelist access isolation, and two-level automatic warehouse location accounting, it achieves full digital control of iron oxide powder from production, testing, warehousing, to external sales. The system strictly limits operation permissions, automatically calculates production and inventory, supports report export and audit traceability, and solves problems such as chaotic management, easily tampered data, unclear permissions, and difficult traceability in traditional systems. It is particularly suitable for high-confidentiality and highly sensitive metallurgical by-product management scenarios. This invention has been practically implemented in steel plants for many years.

Description

Technical Field

[0001] This invention belongs to the field of metallurgical and chemical by-product management technology, specifically involving a digital management method for the entire process of iron oxide powder generated by acid regeneration systems, from production, detection and judgment, inter-warehouse transfer, review and release to external sales. It is particularly suitable for strict management scenarios with multiple permissions, high confidentiality, and traceability. Background Technology

[0002] In the cold-rolled acid regeneration process, iron oxide powder is a high-value, sensitive material involving profit distribution and external sales. The traditional management model has the following prominent problems: Production, testing, inventory, and sales data are scattered and lack unified ledgers, making it difficult to trace the source of disputes. Paper records are easily lost and altered, and batches cannot be linked to test results one by one; The warehouse management is chaotic, there are no records of the transfer between the on-site warehouse and the finished goods warehouse, and the inventory quantity and weight are not accurately calculated. Unclear operating permissions and lack of separation between job and equipment-level permissions pose a risk of unauthorized operation. The lack of mandatory process control at key stages such as review, judgment, and shipment can easily lead to risks such as selling before inspection and shipping unqualified goods. Data statistics rely on manual calculations, and team output, warehouse inventory, and export quantities cannot be automatically summarized.

[0003] Therefore, there is an urgent need for an iron oxide powder management system that can achieve a closed-loop process, multi-level access control, mandatory status transition, and automatic statistical traceability. Summary of the Invention

[0004] This invention provides a method for full lifecycle management and multi-level access control of acid-regenerated iron oxide powder. Through unique batch number binding, status-driven flow, IP whitelist access isolation, and dynamic warehouse location management, it achieves full traceability, controllability, and auditability from production to sales.

[0005] 3.1 Basic Data and Unique Identifier Each batch of iron oxide powder is assigned an iron red package number and an iron red test batch number as unique identifiers. Bind production date, work group, machine group, and shift information; The system integrates two levels of testing data: Baoao Testing (chloride ions, bulk density) and the Technical Center Testing (particle size, all element indicators, etc.).

[0006] 3.2 State-Driven Forced Flow The system uses a fixed state transition and does not allow skipping steps: Add new entry → Pending review Complete testing data → Grade determination Administrator review → Pass / Fail Approved → Warehousing (on-site warehouse) Transfer → Move to finished goods warehouse Export loading → Bulk shipment Supports reverse operations: cancel transfer, cancel outbound. All states are displayed intuitively in different colors on the interface, enabling quick identification.

[0007] 3.3 Multi-level access control and IP whitelist control Device-level permissions: By restricting access via a client IP whitelist, only authorized IPs can perform sensitive operations such as adding, deleting, editing, transferring, and exporting data; Personnel-level permissions: Only administrator accounts are allowed to perform auditing operations; Pre-operation verification: Data cannot be transferred without approval. Unqualified products cannot be shipped out. Data that has already been shipped out cannot be modified arbitrarily. Deletion operations require secondary confirmation to prevent accidental or malicious deletions.

[0008] 3.4 Warehouse location management and automated inventory accounting Set up two levels of storage locations: on-site warehouse and finished product warehouse; The transfer operation automatically reduces the on-site inventory and increases the finished goods inventory. The system automatically compiles statistics in real time: Daily output of each shift (A / B / C category) On-site warehouse and finished goods warehouse classified inventory Daily outbound quantity and total The percentage of each category is calculated automatically. 3.5 Data Query, Export, and Automatic Report Generation Supports multi-dimensional queries by date, work group, storage location, status, package number, and trial batch number; Production ledgers, daily scheduling reports, and workshop daily reports can be exported to Excel format with one click; Automatically generate summary reports for internal management and external auditing.

Claims

1. A method for the whole life cycle management of acid-regenerated iron oxide powder, characterized in that, include: (1) Assign a unique iron red packet number and trial batch number to each batch of iron oxide powder, bind production information, two-level test data and storage location information to form a complete batch file; (2) The process is forced to flow according to the status flow of "entry → judgment → review → warehousing → transfer → outbound", so as to achieve standardized control of the whole process.

2. The method according to claim 1, characterized in that, Device-level access control is implemented using an IP whitelist, authorizing only IPs to perform critical operations such as adding, deleting, editing, transferring, and exporting data. Personnel access restrictions are also applied to restrict and approve these operations.

3. The method according to claim 1, characterized in that, Set up on-site warehouse and finished goods warehouse, and automatically update the inventory on both sides during the transfer operation. When the goods are shipped out, the inventory is deducted in batches and the shipped data is locked.

4. The method according to claim 1, characterized in that, The system distinguishes four statuses by color: unapproved, qualified, unqualified, and outbound, and automatically calculates the daily output, category inventory, outbound quantity, and percentage of each.

5. The method according to claim 1, characterized in that, It supports multi-condition queries and automatic export of ledgers and daily reports, enabling traceability, auditability, and the provision of evidence to external parties.
