In order to prevent the illegal discharge of wastewater from electroplating enterprises, we have designed a concentration of electroplating wastewater monitoring system based on WIA-PA industrial wireless network, which aims at Longxi plating base. WIA-PA industrial wireless network has advantages in stable data transmission and easy deployment, so that the whole project can be completed quickly and well. The application layer software realizes the real-time monitoring of the concentration of wastewater discharge, and the warning safety management function. The practical results show that, this system has greatly improved than foot patrol monitoring method in the traditional monitoring speed and stability. For the plating base intelligent unifi ed management platform laid a good foundation in the future.
