Project background

Shuyang ITAD household waste treatment center is a la÷rge environment facility with intensive and high integrated ★techniques. To meet the requirement to urban household w↕aste modern integrated treatment and the treatment center scientific management₽, in the processing design, philosophy and technolo↕gy about multi-points processing control and automated production line system contro​l have been widely used. The treatment center central control≤ system is the central nervous system of the plant. It no←t only controls and monitors all the equipment running within the plant, but als↓o automatically collects and stores large amount of processing data for analysis and pro&cess. The treatment center central control system uses industrial÷ Ethernet, PLC workstations and many process control sensors and other digital informationl♠ized technologies, to accomplish the optimized production process control, reasγonable production scheduling and reliable product quality.
