How can I feed a time schedule to appliances while using AC voltage source?

조회 수: 5(최근 30일)
My goal is to find the total electricity consumption by each household appliance. Right now, I am trying to build a model of dish washer which needs a schedule to run water pump motor and drying coil=water heater coil.
I have tried following things.
1. signal builder which is helpful to create 0 and 1 at desired time but I found that electric switch with AC voltage supply does not accept the signal from ' signal builder'. switch only accepts physical signals. ( is there any way that we can convert the output of 'signal builder' which can be accepted by 'switch'?.
2. I have tried ' repeating sequence'( signal type: discrete) with ' PS constant delay' which helps to switch the AC source on and off but I am not getting how these functions can be used to feed following schedule: * stage1: water pump on for 15 min stage2: water heater on for 15 min stage3: water pump on for 15 min stage4: drying coil on for 15 min. ( drying coil and water heater coil is same)
is there any other tool in Simulink which is more appropriate to solve this kind of problem?
