Control And Monitoring System

In this paper, a smart and centralized traffic light control and monitoring system is proposed to control the modern transportation systems and make the city safer, using programmable logic controllers (PLCs) and programmable electronic microcontrollers. A camera is used to monitor the mishaps during the traffic flow of vehicles. The system has four modes, i.e., auto-control mode (ACM), manual control mode (MCM), central control mode (CCM), and remote control mode (RCM). In the auto-control mode (ACM), the traffic light signals are controlled automatically through programmable electronic microcontrollers at specific times, while the manual control mode (MCM) controls the traffic light signals manually (on–off switches) according to the traffic congestion. The central control mode (CCM) is considered to be a centralized mode, where the programmable logic controller (PLC) is used by a computer workstation. In this mode, the traffic light signals are controlled by a ladder logic program of the PLC. The third mode, RCM, is linked with the second mode, CCM; in this mode, the traffic light signals are remotely controlled through the software by transferring programmable logic controller (PLC) functions to the software interface. As a result, this transportation system can also be controlled remotely. The designed system delivers suitable, flexible, and reliable control for traffic signaling and transportation.

Programmable logic controller (abbr. PLC) is essential for automation in modern industry. In many colleges, it is also an important course for automation major. Currently, PLC is monopolistic technique with foreign company. Simulation of PLC has become popular scheme for substitute to real PLC. Virtual PLC is a kind of common scheme. Otherwise, virtual PLC is unfavorable of practical training for student. The thesis spread out exposition for a new simulation system, which consists of virtual PLC platform and a printed circuit board. The virtual PLC platform had been programmed under visual C++ by authors. It is a graphical programming tool, and is an interpretive routine too. Based on MCU, the board is developed for communication between virtual PLC and real control objects. The simulation system has been tried out. As an example, traffic light control of intersection shows feasibility and effectiveness.

Traffic Guidance

This research is focused on laboratory based analysis on hardware module of traffic light with Programmable Logic Controller (PLC) software. There are four ways in hardware model for detection of vehicle; each way has one sensor button, three Light Emitted Diodes (LEDs) with individual colors say red, yellow and green represents the traffic light in each lane. Sensor and LEDs are connected to Mitsubishi Programmable Logic Controller (PLC) and each part on hardware being controlled by PLC. Ladder diagrams are programmed by software to monitor the system and helps to improve public transportation services, thereby improving traffic guidance and traffic light control. The system was developed by setting the appropriate time for the traffic lights to respond accordingly. The controller checks the priority and provides an exit signal to the traffic light post to turn the red, yellow or green lights on or off. Finally, the signal lights were successfully controlled by the PLC. Hence the system used in traffic control systems contain low power consumption, low engineering cost and increased safety.

Abstract This research aims to design an automatic garbage collection system using a Programmable logic controller (PLC) and an Arduino Uno waste monitoring system. The function of this tool is to make people easier for clean marine debris, which is usually clean manually. In this case, operators or cleaners are only sufficient to wait for information in SMS if the trash bin is fully loaded. This study used an LDR sensor as input to respond to the state of the wastebasket and a DC motor used as a transmission system in transporting and moving the position of the wastebasket. In addition, using the ultrasonic sensor as input in the trash bin and a GSM SIM 900 A module functions as a medium for sending messages that the trash bin was full. Resultant of this study indicate that the tool can lift ±0.5 kg of waste per hour, with the heaviest weight that can be lifted ±0.7 kg and the lightest weight of ±0.5 kg with the most types of rubbish obtained in the form of plastic and other small debris.
