Monitoring van de waterkwaliteit met behulp van IoT
The rapid economic growth of different nations has brought about various pollution problems. One of the most serious issues lies in water pollution.
Water is an essential natural resource for human survival, and water pollution can damage human health and endanger life safety so the protection of water resources has attracted great attention from all countries.
In order to implement the prevention and pollution control of water resources, the design and implementation of a reasonable and perfect water quality monitoring system is really key. Aanvankelijk, the process of water quality monitoring is and also requires an on-site operation. Bovendien, the monitoring of water quality is not real-time, and the water quality data cannot be intelligently classified and determined.
By using the Internet of Things, we developed an online remote water quality monitoring system.
Het systeem bestaat uit drie delen:
1. The water quality data collection and transmission of monitored nodes. In the monitoring points, the water collection cards of the water quality sensors can be used to transfer the water quality parameter data to the on-site computers. Then after the calculation of the proportion of specific water quality parameters, the system can derive the concentration value of the corresponding parameters. Then the water quality parameters and node ID identification, monitoring time and other information are encapsulated into a JSON object sent to the backend server through the wireless network. Eindelijk, the data is going to be conserved in the MySql database.
2. The design and implementation of water quality classification. Most of the existing water quality classifications are based on the evaluation of a single factor so it doesn’t reflect the comprehensive water quality situation.
