Concentration monitoring system for electroplating chromium and nickel mixed wastewater based on internet of things
Monitoring the concentration of chromium and nickel in wastewater can help identify and treat potential problems in the early stages,reducing the risk of pollution to the natural environment and water resources.Therefore,a concentration monitoring system for electroplating chromium nickel mixed wastewater based on the Internet of Things architecture is designed.In the command layer,LoRaWAN communication is used to connect electrochemical sensors and monitoring systems.The monitoring system can collect real-time data on the concentration of chromium and nickel in waste-water;In the network layer,boxplot is used to identify outliers in the data collected in the command layer and remove these outliers.To ensure the security and stability of data,data is transmitted to the cloud platform through the monitoring system software protocol code in IoT technology.Utilizing the Lonely Forest algorithm in the cloud platform for pattern recognition and monitoring of data transmitted to the cloud platform,the wastewater concentration data is visualized through the perception layer,allowing users to intuitively understand the concentration of mixed wastewater.The experimental results show that the monitoring accuracy of the system in this paper remains above 95%,and the data trans-mission efficiency remains above 96%.It has high monitoring accuracy and good operational perfor-mance.
