Dynamic Industrial Logic Pass Box Controller -- 2

dynamic pass box controller
Dynamic Pass Box Controller (Final Industrial Logic with HMI + HEPA Sensor)
System Description:
The system consists of:
• Two interlocked doors (Door-1 and Door-2)
• 7-inch resistive touch HMI (UART based)
• HEPA filter with differential pressure sensor (2 pipe type)
• UV light
• Blower system
• Buzzer alarm
________________________________________
Door Interlock Logic
• Door-1 and Door-2 must never open at the same time
• If Door-1 is open → Door-2 must remain locked
• If Door-2 is open → Door-1 must remain locked
________________________________________
Operation Sequence
1. User presses Door-1 button
2. If Door-2 is closed → Door-1 unlocks
3. After Door-1 closes → system starts process cycle
________________________________________
Process Cycle
• Blower ON
• UV Light ON
• Timer value taken from HMI
After timer complete:
• Blower OFF
• UV OFF
• Door-2 unlock
________________________________________
HMI Functions (Editable Settings)
• UV Time (0–999 sec)
• Blower Time
• Door Delay Time
• Alarm Time
• Pressure Setpoint (Pa)
________________________________________
Monitoring on HMI
• Real-time Pressure (Pa)
• Door Status (OPEN/CLOSE)
• System Status
________________________________________
HEPA Differential Pressure System
• Sensor: MPXV7002DP (low cost)
• Type: Dual port (2 pipe connection)
Connection:
• Port 1 → HEPA chamber
• Port 2 → Outside air
Signal:
• Analog output (0–5V) → MCU ADC
________________________________________
Alarm Conditions
• Pressure below setpoint → Alarm
• Both door open attempt → Alarm
• Door open too long → Alarm
Action:
• Buzzer ON
• Warning on HMI
