Rod and wire continuous rolling loop set value input control device and system for controlling device

The invention relates to a rod and wire continuous rolling loop set value input control device. The device comprises a first selecting module, a first switching module, a first information acquisition module, a first input module and a second switching module, wherein the first selecting module is used for selecting a loop needs to be corrected; the first switching module is used for switching a control mode into a loop set value input mode; the first information acquisition module is used for obtaining preset value variation parameters; the first input module is used for correcting a loop set value according to the preset value variation parameters through a bat-handle switch of a control console rolling mill; and the second switching module is used for cancelling loop correction selection and switching into a non loop set value input mode. An operator can operate conveniently, and operability of loop correction in the production process is achieved. 本发明涉及种棒线材连轧活套设定值输入控制装置，包括有第选定模块，用于选定需要修正的活套；第切换模块，用于把控制模式切
