Project background

Shuyang ITAD household waste treatment center is a large environment facility with intensive and high integrated techniques. To meet the requirement to urban household waste modern integrated treatment and the treatment center scientific management, in the processing design, philosophy and technology about multi-points processing control and automated production line system control have been widely used. The treatment center central control system is the central nervous system of the plant. It not only controls and monitors all the equipment running within the plant, but also automatically collects and stores large amount of processing data for analysis and process. The treatment center central control system uses industrial Ethernet, PLC workstations and many process control sensors and other digital informationlized technologies, to accomplish the optimized production process control, reasonable production scheduling and reliable product quality.
