Measurement management platform:

The metrology management platform is a comprehensive software platform that integrates data input, processing, analysis, and report generation. It aims to help enterprises achieve automation, informatization, and intelligence in metrology work. Its main functions include data input and storage, data processing and analysis, report generation and export, etc. It is widely used in metrology management work in various industries.

1. Homepage: including login information, notifications and announcements, to-do list, approval progress, recent experiments, today's experiments, experiment statistics, equipment expiration, etc.

2. Basic information: Management of relevant basic data for experimental operation, management of commissioning units, storage location information, and sample information.

3. Equipment ledger: Due to the variety of measuring instruments, complex sources, allocation from other projects, subcontracting, and procurement from different regions in the project, it is particularly important to establish a measuring instrument ledger and instrument file, which is also the fundamental work of measuring instrument management.

4. Calibration and verification: Certificate editing supports multiple data entry methods, such as automatic device upload, manual input, and file import, ensuring fast and accurate data entry. Certificate viewing allows for the review and approval of certificates. Certificate printing supports generating reports in various formats according to user needs, including tables, charts, etc. Users can also export reports to common file formats for convenient data sharing and transmission.

5. Statistical query and analysis: Equipped with various data processing and analysis tools, it can automatically process, statistically analyze, and trend predict the entered measurement data, helping users quickly obtain valuable information.

6. Quality assurance management: project initiation and qualification management, calibration standards, printing templates and other quality data management.

7. Logistics management: facilitates the management of company logistics related data by users, such as company documents, information materials, procurement management, supplier management, etc.

8. System management: Basic data management for system operation, role management, department management, user management, menu management, system settings, etc.

9. Customer service system: WeChat system, QR code progress inquiry system, online inquiry system, customer measuring instrument management system, certificate verification system, self-service download system, complaints and suggestions, etc.
