Dearto - Model DTSL Pro - Temperature and Humidity Meter Verification System

• 1. Unattended - fully automatic verification/calibration

Complete the entire calibration process fully automatically without manual intervention, improving work efficiency and reducing labor costs; automatically perform multi-point temperature and humidity control, automatically position and photograph the temperature and humidity meter, automatically identify the digital temperature and humidity meter, and automatically calculate the calibration results And determine the calibration conclusion to realize intelligent control of the equipment.

• 2. Stable performance, data security and reliability

The system uses a high-definition camera to take pictures of the temperature and humidity meter, and uses artificial intelligence and software-specific algorithms to automatically identify temperature and humidity values. At the same time, it archives the original pictures and identification data, which is more stable and reliable and can solve the reading errors, reading deviations, and readings caused by traditional manual readings. Data cannot be reviewed.

• 3. Artificial intelligence learning ability

The biggest advantage of the system is its automatic learning ability, and the recognition of new temperature and humidity meters can be added later. The identification part has an independent module and can be independently upgraded. For new thermometers and hygrometers, users only need to provide pictures of the thermometer and hygrometer. After training, the automatic identification of the new thermometer and hygrometer can be realized by upgrading the identification module.

• 4. High recognition efficiency

The temperature and humidity calibration chamber in the system will be controlled sequentially according to the calibration points required by the regulations. When each calibration point is stable, the system can automatically collect according to the stabilization time set by the user. During the entire calibration process, the time for photographing and identifying is basically negligible compared to the time for temperature and humidity control and stabilization.

• 5. Database management functions

In the database management software, enter the inspection information of the inspection order into the database, select the temperature and humidity meters that need to be calibrated this round, and then automatically arrange and combine them through the operating software, and hang the meters on the inner cylinder rack in the temperature and humidity box. Corresponding hole position, and set the control point of the temperature and humidity controller to the data point that needs to be calibrated. After starting work, the identification data and images can be automatically identified and uploaded. Editing, querying, and deletion can be realized in the database management software. And it can export Office documents to realize data electronic document storage.

1. This software uses the MySql database, which can realize online testing inside and outside the network, facilitate laboratory data management in different locations, and realize data sharing and multi-machine operation.
2. The database management software can use the image scanning and input function to automatically input the valid information of the inspection form into the information column. The operation is convenient and fast, reducing the tedious workload.
3. The database operation software can import the original calibration data into excel documents and establish the traceability of the data.
4. The calibration and testing software can intelligently analyze the properties of temperature and humidity instruments {digital display, pointer), and identify and display effective information to facilitate the calibration staff's analysis and judgment.

DTSL Pro-svr3 fully automatic thermo-hygrometer calibration system supports automatic positioning, automatic photography, automatic collection, automatic identification, automatic calculation, and automatic judgment. It can complete the entire calibration process automatically without manual intervention and can realize unattended detection mode. This device can automatically control the temperature and humidity of the calibration chamber, monitor the temperature and humidity values of the calibration box in real time through a dew point meter, and automatically make stability judgments. After meeting the stable conditions, the system automatically controls the camera robot, data collection device, automatic identification system, temperature and humidity calibration box, precision dew point meter, etc. to position them in sequence to the thermometer being tested. It has a built-in intelligent rotation positioning device that automatically receives the controller signal and realizes data automation. Collect, take photos, archive and automatically identify the temperature and humidity values, and automatically enter them into the host computer. Based on the inspection of the calibration points, the calibration results and calibration conclusions are automatically calculated.
