SCM-1 Suspended Ceiling Adaptor

SCM-1 Suspended Ceiling Adaptor

SCM-1 in the supply of water at the same time, water and energy saving also have strict requirements under the control of the water level will have certain requirements, so the use of general-purpose frequency converter to drive the pump motor, the different requirements of the water level to determine the different frequency of power supply, which determines the different amount of water intake. Under the premise of safe control of water level, the system also has some necessary requirements: liquid level display, super level alarm, liquid level change curve printing and so on.

SCM-1 the controlled object is the water level of the water tower, and the water level of this controlled object is characterized by non-linear, large inertia, so there is no use of conventional PID regulator to form a closed-loop control system, but the use of the BANG-BANG control regulator to the frequency converter to the time-real control.

SCM-1 is the core of this control system. It should not only fulfill the control task, but also the function of changing frequency. And 8031 microcontroller plays the functions of liquid level display, curve printing and alarm here.
