Dynamic Industrial Logic Pass Box Controller

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 ________________________________________ Additional Features • Manual mode (HMI control) • Auto mode • DWIN HMI DMG80480T070_01WTR | 7” | 800×480 | UART | 5V | Q Madam,/sir this is the material list for reference, you can use any component as per your which should be low cost and good quality [login to view URL] Controller Section (PCB SMD) • ATmega328P-AU | TQFP-32 | 5V MCU | Qty: 10 • Crystal 16 MHz | SMD 3225 | Qty: 10 • Capacitor 22pF | SMD 0805 | Qty: 20 • Capacitor 0.1µF | SMD 0805 | Qty: 60 • Capacitor 10µF | SMD 1206 | Qty: 30 ________________________________________ Power Supply • SMPS 230VAC → 12V DC (2A) | Qty: 10 • AMS1117-5.0 | SOT-223 | Qty: 10 • Capacitor 1000µF / 25V | Qty: 20 • Capacitor 470µF / 25V | Qty: 10 • Diode M7 (SMD) | Qty: 30 ________________________________________ Relay Control • Relay SCS-5-DC12V | 12V | 10A | Qty: 50 • ULN2003A | SOP-16 | Qty: 10 ________________________________________ Buzzer • Active Buzzer 5V PCB Mount | Qty: 10 ________________________________________ LED + Resistor (SMD 0805) • LED Red | Qty: 20 • LED Green | Qty: 20 • LED Yellow | Qty: 20 • Resistor 220Ω | Qty: 60 • Resistor 1kΩ | Qty: 80 • Resistor 10kΩ | Qty: 120 ________________________________________ • Password protected settings (optional) BOM
