Software system part:

1. It can simultaneously display real-time status of all detection devices, radiation dose rate, temperature, wind speed, atmospheric pressure, rainfall and other data of each detector

2. Can dynamically add collectors and set different first and second level alarm thresholds

3. While the system is measuring, the software displays red, yellow, and green warning lights. While recording and saving data, it also triggers sound and light alarms based on the user set alarm threshold, displaying the measurement status

4. Different curves for real-time display of different "collection points", "detector names", and "sensing items" can be selected

5. The selection items for curve display "sensing items" include wind speed, auxiliary input, atmospheric pressure, wind direction, radiation dose rate, bias voltage, battery voltage, temperature, rainfall, etc

6. While displaying the curve, the collected historical data and alarm historical data can also be displayed

7. In the curve graph, you can choose to display both the average curve and the alarm line simultaneously, and distinguish them with different colors

8. In addition to automatically selecting the display range, the display range of the curve graph can be set according to different user requirements, as well as zooming in and out of the curve graph

9. It has data statistics function, which can display historical data curves of different collection points and sensing items such as wind speed, auxiliary input, atmospheric pressure, wind direction, radiation dose rate, bias voltage, temperature, rainfall, as well as first and second level alarm thresholds during selected time periods

10. Horizontal curve comparison can be performed on data collected from different points within a selected time period, and vertical curve comparison can also be performed on data collected from different detectors within different time periods
