working principle:

Based on the visual steel tape inspection device, an integrated aluminum profile is used as the platform, multiple cameras, and an automatic hanging mechanism to accurately achieve fully automatic and high-precision measurement of steel tape readings.

The instrument manually fixes the steel tape measure on the platform fixture, and then selects the model, specifications, and inspection point information of the tested ruler on the calibration software. Click the "Start Calibration" button, and the calibration system triggers the camera to start collecting information. The computer comprehensively calculates the line pattern information to be calibrated based on the calibration parameter information and the actual shooting scale information. The computer analyzes the data, calculates the line pattern indication error of the tested ruler, and makes a judgment conclusion according to the calculation method specified in the regulations.

The system supports two modes of calibration: automatic calibration and manual calibration. The collected data is judged as qualified according to the calibration regulations. The entire measurement process is fast and accurate, greatly reducing the labor intensity of the operator. After the calibration is completed, the calibration report can be generated and printed immediately.

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.
