  5. 5. BLOCK DIAGRAM SENSOR (ENTRY) PLC SENSOR (EXIT) RELAY LCD DISPLAY LIGHTS AND FANS
  6. 6. FLOWCHART START 1 LIGHT AND A FAN ON COUNTER INCREMEN TED BY 1 IF PERSON ENTERS IF PERSON EXITS COUNTER DECREMEN TED BY 1 IF COUNT >5 OR MULTIPL E OF 5 IF TOTAL COUNT-5 1 LIGHT AND A FAN OFF DISPLAY
  7. 7. Controller & Simulation tool  SIMATIC controllers S7-1200  Power supply 120/240VAC with DI14×24VDC sink/source  DQ 10×Relay and AI2 on board  6 High-speed counters & 4 pulse O/Ps on board  Up to 3 Communication module & 8 signal modules foe I/O expansion  0.04 ms/1000 instruction execution speed  PROFINET interface for programming  HMI and PLC to PLC communicatin  TIA PORTAL

  9. 9. ADVANTAGES 1.Main advantage of this project is that it helps in energy conservation. Because when there is nobody inside the room then lights are automatically turned off. 2. Human efforts to count the number of person is eliminated. Since this project does the automatic person counting with the help of two sensors installed on door frame. 3. Savings energy.
  10. 10. APPLICATION Digital Visitor Counter can be used in various rooms like  seminar hall,  conference hall where the capacity of room is limited and should not be exceeded. Project will display actual number of persons inside the room.
  11. 11. FUTURE DEVELOPMENT 1. Voice alarm system can be added to indicate that room is full & persons can’t enter inside. 2. We can increase the maximum number of persons that can be counted by implementing the external switches and leds. 3. We can send this data to a remote location using mobile or internet.
