DESIGN AND IMPLEMENTATION OF AN AUTOMATIC PARKING GATE PROTOTYPE SYSTEM BASED ON THE OMRON CP1E-N20 PROGRAMMABLE LOGIC CONTROLLER

Abstract

This study aims to design and develop a prototype of an automatic parking door crossing system

based on the Omron CP1E-N20 Programmable Logic Controller (PLC) which is integrated with

Radio Frequency Identification (RFID) and Internet of Things (IoT) technology as an industrial

automation learning medium. The system is designed using the concept of input, process, output

where the input includes RFID Reader and proximity sensors which are used to detect and identify

vehicles. The data is then processed by the Omron CP1E-N20 PLC using a ladder diagram on the

CX-Programmer and the ESP-32 using the C++ language on the Arduino IDE. The system output

is in the form of a servo motor as an automatic bar drive, LCD as a system status display, ESP-32

Cam as visual monitoring, and a monitoring website to display UID data, access status, time, and

vehicle images in real-time. The research methods include observation of the parking system at

Solo Square Mall, benchmarking, prototype design, program creation, system testing, cycle time

testing using a single-sample t-test, and evaluation using the Failure Mode and Effects Analysis

(FMEA) method. The cycle time test was carried out 30 times by comparing the average cycle

time of the prototype with a reference value of 8 seconds. The test results showed that the system

was able to validate RFID, open and close bars automatically, and send monitoring data to the

website properly. The results of the t-test show that the average system cycle time is faster than

the reference value so that the system is considered to have good and consistent performance.

Furthermore, an evaluation was carried out using FMEA which showed that the system had a

good level of reliability after mitigating several potential failures in the main components.
