The control system of concrete batch plant has the functions of system setup, over-thrust compensation, weighing index calibrating, dosing management, real time monitoringconcrete batching plant and control, and production report printing. Various data and analogue dosing process chart can be displayed at real time in a friendly interface and with graphics and texts. This facilitates the operation. Its operation has a extremely high reliability.

It also has complete working modes and is convenient in selecting. The Select switch in the operation panel enables the shifting among the full-auto, semi-auto, and manual modes of the system.

In manual working mode, the action time of each control component on the operation panel is determined by the state of the corresponding button and the restricted condition of the system. When the restricted condition is not met, the button action will be ignored. Once the action is responded, the corresponding button and indicator in the control panel will be lightened.

In auto mode, the control components take actions periodically according to the time and mode preset by software. The operators can see the working status of the whole station from the indicators in the control panel.

PLC control mode is adopted for weighing. The influence of dropping and the impact of aggregates on the precision of weighing have been specially considered in the making of data processing software so as to increase the precision of weighing and ensure the quality of the concrete.
