1. About the water pipe network monitoring system
1. Our leakage point positioning is based on big data and intelligent algorithm calculation results, with very high accuracy;
2. At present, the accuracy of big data analysis is more than 9 5%;
3. Compared with manual leak detection, the sensitivity of our sensor is higher than that of human ear, and there is no false alarm.
4. In order to be responsible for customers and reduce the difficulty of customer maintenance, it is suggested that customers review the information on site after the leakage point is identified and confirmed by the big data platform to provide more specific information for customer maintenance work.

2. What are the disadvantages of artificial listening?
1. Accuracy less than 50%;
2. Its effect is affected by the background noise and the experience of the leak detection personnel. For buried pipelines with deep depth, it is difficult to detect the leakage point downward;
2. Real-time dynamic monitoring cannot be realized; the problem of continuous decrease of leakage rate cannot be solved.
