This system, based on the Windows 7 operating system, integrates configuration software with PLCs to collect and process data during the testing process, and saves it securely. Data is non-modifiable and non-deletable, ensuring its persuasiveness. Test data is automatically saved on the computer and can be easily retrieved and printed at any time based on the test number or test time. Below is a detailed explanation of the system's operational procedures.

Double-click the icon after the computer boots up normally.A password input dialog box will pop up. Enter the password 935488, confirm, and the data collection software will enter the running state.

2. Initially, you'll enter the homepage window. The software includes operation instructions that can be referred to while performing specific actions.

Click here for page operation instructions.

Clicking any button will now display a blue border, along with a popup explaining the button's related feature settings.

Click on other buttons, the previous explanation will automatically exit. Click 'Exit' to leave the view of the operation instructions, at which point you can normally switch windows and perform operations through the buttons. Let's enter the monitoring screen.

3. Pre-test preparation, parameter settings.

Upon entering the monitoring window, there will be a prompt for parameter settings. We have pre-set some commonly used parameters for easy access in the future.

The blue section contains 5 preset groups that can be accessed at any time, while the white section allows for direct text input. This part is expected to be modified infrequently.

Be mindful that our bubble monitoring defaults to the first option. Also note that the icons differ.

Prior to initiating the test, we can zero-calibrate the sensor to minimize measurement errors, select an appropriate range sensor based on the measurement requirements, and calibrate the sensor range.

Un calibrated, there will be a prompt in the window. Once the relevant parameter settings are completed, you can proceed to the normal data collection and testing process.

Some critical parameters are not set correctly; there will be corresponding prompts. Please check during use.

4. Data Testing and Collection

First, click the water and gas switch, select the corresponding water pressure or air pressure, click "Start Test," then choose the test item by clicking on the required project with the mouse. The corresponding icon will turn red, indicating it has been selected. Set the corresponding parameters, allow for pressure drop, hold pressure time, as shown in the blue box above. Click "Continue Test," and the pump will automatically increase pressure. Once the set pressure is reached, it will automatically shut off and hold pressure. A pressure curve will appear in the right box; a straight line indicates no pressure drop, while a stepped decline shows where there are leaks.


During the test, if an anomaly is detected and the test needs to be terminated, click "End Test" to interrupt the valve test. If a valve component needs to be replaced, click "Continue Test." Be sure not to click "End Test" or print the report, as this will result in the test data for the same valve not being saved in the corresponding box for that valve. For specific instructions, refer to the operation manual included in the software.

Table printing: After testing is completed, click "Table Print" and the printer will automatically print out the test data. Before printing, you can click "Test Report" to view the printout. After printing, the relevant data will also be saved into the system.

6. To retrieve saved data, access the saved data window and search using either the query number on the test report or the specific test time. Extract and generate a table from the saved data.

After data extraction, click on the preview and save table to view the extracted data in the table.

If a pressure curve during testing is required, click on "Curve Production," and the corresponding curve can be generated based on the saved data at that time.

7. Historical Curve Search: Real-time curves from past tests can also be viewed through the Historical Curve dialogue box.

Click the red icon below to accurately search for pressure-time curves within a specific time period by using time as the filter.

If you're unclear about any aspects of the software usage, refer to the internal operation instructions within the software as much as possible.
