Human Health Monitoring System

Abstract: The scope of this paper is to present the initial steps in the implementation of a traffic light control system using PLC & SCADA”. The SCADA with PLC logic ladder is used for monitoring the system and helps in improving public transport services that also improve traffic guidance. The system developed by setting the appropriate duration for the traffic signals to react accordingly. The critical timing operation is required to be carried out under the existence of heavy traffic conditions. The system for traffic control system must contain low power consumption, low project cost, increases safety. The PLC checks the status of the sensors. The system resolution is dependent on the output provided by the sensors, then PLC checks the priorities and then provide output signal to the traffic light poles for ON or OFF the red, yellow or green lights and ON time is dependent on the specific priorities. The new timing scheme that was implemented promises an improvement in the current traffic light system and this system is feasible, affordable and ready to be implemented especially during peak hours, off hours and pedestrians. The PLC checks the status of the sensors. The system resolution is depend on the output provided by the sensors, Then PLC checks the priorities and then provide output signal to the traffic lights poles for ON or OFF the Red, yellow or Green lights and ON time is depend on the specific priorities. The roads are opened in that manner that east road, west road, north road and then south road is open.
