To reduce the deviation of automated dosing,design a control cloud platform for sewage treatment plant stations based on PLC technology.Build a hardware system structure based on computer terminals,PLC controllers,PC terminals,and other devices.Select wireless transmission equipment and establish a communication network to collect and transmit sewage treatment data on the cloud platform.Using TIA Portal V16 software,complete the dosing program programming,and based on PLC technology,achieve automatic dosing control.The results indicate that the platform can reduce the deviation of dosage and enhance the effectiveness of sewage treatment in the process of sewage treatment control.
