| Abstract: | A low-choose section and a pretreatment tache of block-net were added to the original control program aiming to solve the block-net problem of traditional pressure screen control. S7400 control station of Simens was adopted to achieve our goal. When the pressure screen begins to come out the trend of block-net, DCS begins to carry out the pretreatment tache. The application in practice proves that this program improves greatly the security, dependability and stability of system and it is meaningful for popularization and application. |
