Design of Medical Elevator Control System Based on PLC
Compared with traditional elevator control systems,medical elevator control systems need to pay more attention to the smoothness of the elevator lifting process to ensure patient comfort.Therefore,it is necessary to design a medical elevator control system.Firstly,Siemens S7-1200 series PLC is used as the main control unit,and ACS880 frequency converter is used to drive the traction motor and door motor.Then,through the compilation of ladder diagrams,functions such as call response,level switch detection,and target floor operation and stop are implemented.Finally,add elevator operation safety protection function,which can immediately alarm in case of dangerous situations.After testing,the system is stable and reliable,with smooth speed regulation and high safety,and can be applied to various medical environments.
