Vacuum Fan Motor Protection Logic
ADC and real current
Designed Parameter and Vacuum degree
Quiet Mode: PWM = 8%, Vacuum Degree = 600Pa
Standard Mode: PWM = 16%, Vacuum Degree = 1000Pa
Medium Mode: PWM = 40%, Vacuum Degree = 2000 Pa
Strong Mode: PWM = 89%, Vacuum Degree > 4000 Pa
The Logic of decrease the PWM automatically
Strong Mode
Battery Level >= 80%, PWM 89%, Vacuum Degree > 4000 Pa
Battery Level >= 70%, 63% <= PWM <= 86%, the PWM will reduce 1% per 1 minute
Battery Level >= 60%, 63% <= PWM <= 80%, the PWM will reduce 1% per 1 minute
Battery Level >= 50%, 63% <= PWM <= 77%, the PWM will reduce 1% per 1 minute
Battery Level >= 40%, 63% <= PWM <= 71%, the PWM will reduce 1% per 1 minute
Battery Level >= 30%, 63% <= PWM <= 68%, the PWM will reduce 1% per 1 minute
Battery Level < 30%, PWM = 63%
Medium Mode
Battery Level >= 80%, PWM 40%, Vacuum Degree 2000 Pa
Battery Level >= 70%, 29% <= PWM <= 38%, the PWM will reduce 1% per 10 minutes
Battery Level >= 60%, 29% <= PWM <= 36%, the PWM will reduce 1% per 10 minutes
Battery Level >= 50%, 29% <= PWM <= 34%, the PWM will reduce 1% per 10 minutes
Battery Level >= 40%, 29% <= PWM <= 32%, the PWM will reduce 1% per 10 minutes
Battery Level >= 30%, 29% <= PWM <= 30%, the PWM will reduce 1% per 10 minutes
Battery Level < 30%, PWM = 29%
Main Brush Motor Protection Logic
ADC and real current
Designed Parameter
PWM = 65%, Rotation Speed = 1100rpm
The Logic of Protection based on current
Detect 90s, if 0.42A <= current <= 0.6A in 70% of 90s, go into slight protection mode
The main brush moto stop 2min then start again
Detect 30s, if 0.6A <= current <= 1.2A in 70% of 30s, go into mid protection mode
The main brush moto stop 2min then start again
Detect 5.2s, if 1.2A <= current <= 1.6A in 70% of 5.2s, go into strong protection mode
1st go into this protection mode, the main brush stop 5s
If not trigger this protection mode in 15s, recover count to 0 and the logic of the first time go into this protection mode
else count +1
If not trigger this protection mode in 15s, recover count to 0 and the logic of the first time go into this protection mode
else count +1
2nd go into this protection mode, the main brush stop 10s
If not trigger this protection mode in 25s, recover count to 0 and the logic of the first time go into this protection mode
else count +1
If not trigger this protection mode in 25s, recover count to 0 and the logic of the first time go into this protection mode
else count +1
3rd go into this protection mode, the main brush stop 1mrin
If not trigger this protection mode in 125s, recover count to 0 and the logic of the first time go into this protection mode
else count +1
If not trigger this protection mode in 125s, recover count to 0 and the logic of the first time go into this protection mode
else count +1
4th go into this protection mode, the main brush stop 5min
If not trigger this protection mode in 10min+5s, recover count to 0 and the logic of the first time go into this protection mode
else count +1
If not trigger this protection mode in 10min+5s, recover count to 0 and the logic of the first time go into this protection mode
else count +1
Detect 2.2s, if 1.6A <= current in 90% of 2.2s, go into disaster protection mode
1st go into this protection mode, the main brush stop 5s
If not trigger this protection mode in 15s, recover count to 0 and the logic of the first time go into this protection mode
else count +1
If not trigger this protection mode in 15s, recover count to 0 and the logic of the first time go into this protection mode
else count +1
2nd go into this protection mode, the main brush stop 10s
If not trigger this protection mode in 25s, recover count to 0 and the logic of the first time go into this protection mode
else count +1
If not trigger this protection mode in 25s, recover count to 0 and the logic of the first time go into this protection mode
else count +1
3rd go into this protection mode, the main brush stop 1mrin
If not trigger this protection mode in 125s, recover count to 0 and the logic of the first time go into this protection mode
else count +1
If not trigger this protection mode in 125s, recover count to 0 and the logic of the first time go into this protection mode
else count +1
4th go into this protection mode, the main brush stop 5min
If not trigger this protection mode in 10min+5s, recover count to 0 and the logic of the first time go into this protection mode
else count +1
If not trigger this protection mode in 10min+5s, recover count to 0 and the logic of the first time go into this protection mode
else count +1
Left and Right Wheel Protection Logic
Detect 5 min, if .0.5A <= current <= 0.7A
The wheel stop 5s
Detect 1min, if 0.7A <= current <= 1A
The wheel stop 5s
Detect 3s, if 1A < current
The wheel stop 5s
In a single clean session, if 4 times were detected, the robot will alarm and stop
Side Brush Motor Protection Logic
0.1A < current
The side brush working on 1s and stop 2s
