Automatic Car Parking and Fire Detection System Using PLC

Abstract

In the modern-day city scene, the situation is such that there is a greater demand toward intelligent and effective parking systems because of increasing the density of vehicles and limited parking spaces. This thesis gives details on the design and actualization of automated car parking and fire tracking system which is operated by Programmable Logic Controller (PLC) and is monitored using a laptop-based system using Delta HMI software. This system has facilitated automated gate control, detection of parking slots and real-time status indication via relays, actuators and infrared (IR) sensors. LEDindicators are used at the entry gate and can inform the driver of free parking slots to alleviate the problematic parking process. Alongside with the parking system, the project will have a fire detection application. Sensing of rich fire or smoke is done usingsensors installed in different zones of the parking area to sense hazards. When the detection is made a buzzer will sound and immediate signals will be sent to the operatorvia the HMI. The status of all activities, such as the gate position, the slot status, and fire alerts, are viewed in real-time through an RS232 communications interface between the PLC and the laptop. The system guarantees advanced security, efficiency of operation and convenience to its users. It minimizes the necessity to control it manually, as well as enhances the trustworthiness of parking activities in the case of public or business scenes. This project shows how intelligent parking and safety can be done efficiently, and cost-effectively with an industrial automation approach; this is scalable.
