How does the automatic control system of mobile mixing station work

In both general fixed mixing station and mobile mixing station, the control system plays a very important role in the whole set of equipment, which coordinates the equipment running work. The current majority of the electric control system of concrete mixing station use industrial PC, work station and field control station are based on PLC, and it can automatically weigh, feed, mix and discharge raw materials according to the predetermined formula.

YHZS25 Mobile mixing station generally needs to set up automatic and manual two kinds of control modes. Manual work is mainly used in the system maintenance and software debugging, and commonly used in production process automatically. Therefore, manual, automatic selection and corresponding buttons should be set up, and indicator lights should be set for each button, so as to facilitate error checking when the system operation is abnormal. Automatic control can be used when the device is running normally.

The process of concrete from raw material to finished product is metering, conveying, feeding, stirring and discharging. Each link is completed by a corresponding device component. The operation of these devices is managed centrally by the control system, and the operation status of each part is displayed on the computer screen of the control system. System logic control is mainly responsible by PLC, but to accept all kinds of switches, buttons and contactor state such as the input signal and the command of PC, so as to realize the control of various actions, including the ingredients of instrument start-stop, motor start-stop control, the order of the chain control and protection control and so on.
