3 INTRODUCTION INTRODUCTION Traffic lights are signalling devices positioned at or near road intersections, pedestrian crossings and other locations to control competing flows of traffic. Traffic lights were first installed in 1868 in London, United Kingdom; now used in almost every city of the world. Traffic lights alternate the right of way accorded to road users by displaying lights of a standard color (red, yellow and green) following a universal color code (and a precise sequence to enable comprehension by those who are color blind. PURPOSE AND SCOPE A traffic light installation on a three-way crossroad is designed by using ladder logic in TIA Portal. Our Programmable logic controller is SIEMENS S7-1200(CPU-1214C-24V-DC/DC/DC).The system should be working properly without an error to avoid accidents in the traffic.the system has one switch and one traffic sensor. The system should work synchronized with the sensors. The most important part of the project is to design the visual part of the project by using Wonderware INTOUCH.All of the real elements should be represented in the INTOUCH and these elements should be synchronized with the S PLC in order to observe what is going on the crossroad. Also a scenario should work on intouch system to show who is using the road at that time.cars should move with respect to the scenario of the project. Page 1

4 TOOLS TOOLS SIEMENS SIMATIC S The S programmable logic controller (PLC) provides the flexibility and power to control a wide variety of devices in support of your automation needs. The compact design, flexible configuration, and powerful instruction set combine to make the S a perfect solution for controlling a wide variety of applications. The CPU combines a microprocessor, an integrated power supply, input circuits, and output circuits in a compact housing to create a powerful PLC. The S family provides a variety of signal modules and signal boards for expanding the capabilities of the CPU. You can also install additional communication modules to support other communication protocols. Due to the compact modular design with a high performance at the same time, the SIMATIC S is suitable for a wide variety of automation applications. Its range of use extends from the replacement of relays and contactors up to complex automation tasks in networks and within distributed structures. Page 2

5 TOOLS TIA PORTAL The Totally Integrated Automation (TIA) Portal software provides a user-friendly environment to develop, edit, and monitor the logic needed to control your application. The TIA Portal provides the tools for managing and configuring all of the devices in your project, such as PLCs and HMI devices. As a component of the TIA Portal, STEP 7 Basic provides two programming languages (LAD and FBD) for convenience and efficiency in developing the control program for your application. The TIA Portal also provides the tools for creating and configuring the HMI devices in your project. The most important steps in TIA Portal that I used are : Creating the project Configuring the hardware Networking the devices Programming the PLC Loading the configuration data Page 3

6 TOOLS WONDERWARE INTOUCH V10 Wonderware InTouch is the quickest and easiest way to create human- machine interface InTouch is used in widely area including food processing, semiconductors, oil and gas, automotive, chemical, pharmaceutical, pulp and paper, transportation, utilities, and more. By using InTouch, you can create powerful, full-featured applications that exploit the key features of Microsoft Windows,graphics, networking and more. InTouch can also be extended by adding wizards, generic objects, and creating InTouch QuickScript extensions. InTouch consists of three major programs, the InTouch Application Manager, WindowMaker and WindowViewer. The InTouch Application Manager organizes the applications you create. It also is used to configure WindowViewer as an NT service, to configure Network Application Development (NAD) for client-based and server-based architectures, to configure Dynamic Resolution Conversion (DRC) and/or distributed alarming. WindowMaker is the development environment, where object-oriented graphics are used to create animated, touch-sensitive display windows. These display windows can be connected to industrial I/O systems and other Microsoft Windows applications. WindowViewer is the runtime environment used to display the graphic windows created in WindowMaker. WindowViewer executes InTouch QuickScripts, performs historical data logging and reporting, processes alarm logging and reporting, and can function as a client and a server for both DDE and SuiteLink communication protocol.

19 HMI WITH INTOUCH HMI WITH INTOUCH Firstly, I draw the equivalent scheme of the crossroad and then put the elements in their own places by using some special settings that INTOUCH provides us. The most important thing is that we should synchronize HMI system and PLC carefully.in order to synchronize them we should assign some special memory bits to the ladder program in TIA Portal for inputs coming from TIA Portal. M1.0 and M1.1 are the bits that synchronize the inputs of the system as you saw in the ladder program and its explanations. Page 17

21 HMI WITH INTOUCH PROGRAMMED SCRIPT CODES IN INTOUCH The codes below are my way to move cars in the correct order in every situation of the crossroad lights. IF G1==1 THEN CAR1= CAR1 +8; IF (CAR1 >= 930) THEN CAR1=0; IF (G1==0 AND CAR1==200) THEN CAR1=200; IF (G1==0 AND (CAR1<200 OR CAR1>200)) THEN CAR1=CAR1+40; IF PG==1 THEN P= P+3; P2= P2 + 3; IF (P>= 160 AND PG==1 )THEN P=0; IF (P2 >= 160 AND PG==1)THEN P2=0; Page 19

24 REAL DEVICES IN A TRAFFIC LIGHT INSTALLATION PEDESTRIAN LANTERNS These lanterns are produced using the same modular construction techniques and many of the same components used in producing the Aldridge Traffic Systems ATS range of vehicle lanterns. Many component parts of the housing are therefore interchangeable. The pedestrian lantern housing therefore features: Durable thermoplastic components Exceptional structural strength U.V. stabilised components Adjustable lantern mounting centres Injection moulded or aluminium pressure diecast modular housing components Suits all weather and operating environments Available in 200mm and 300mm lanterns AUDIO TACTILE PEDESTRIAN DETECTORS The system comprises two separate units, a post mounted weatherproof box which accommodates the electronic control circuitry, power supply and ambient noise monitor microphone plus an Aldridge Traffic Systems(ATS) audio tactile pushbutton assembly. The push-button assembly accommodates the tactile transducer fitted to the front escutcheon plate and also houses the audio signal transmitter. Two models are available, the push-button assembly as illustrated or an ATS CW series type assembly. Audio Tactile Pedestrian Detector Push Button Assembly Representing a major technology advance from ATS, the audio tactile detector and push-button assembly, is available with a selection of either audio only, tactile only or audio plus tactile indication. The audio tactile facilities can be partnered with either the ATS pedestrian push-button assembly, where uniformity atexisting installations or visual wait signindication is desired. Page 22

25 REAL DEVICES IN A TRAFFIC LIGHT INSTALLATION PIEZOELECTRIC TRAFFIC SENSORS Piezo Sensors are an axle detection sensor that is installed in the roadway (mostly permanent but can be temporary). The sensor is embedded in the lane of travel and can collect count, classification, and Weigh-In-Motion data. Typically a class I sensor is used for weigh-in-motion application while class II sensors are used to collect axle classification data. Piezo sensors work by producing a signal (voltage and current) when an axle/tire comes in contact with them in the roadway, This signal is detected by the electronics in a counter/classifier. The sensors embedded in the roadway are extremely accurate at measuring axles strikes. They are used in application for counting, classification (speed and axle), weigh-in-motion, tolling and even law enforcement installations such as speed and red light running. CONCLUSIONS Designing a Traffic Light Installation system on a Wondareware INTOUCH taught me lots of knowledge about HMI systems. Firstly I draw the crossroad very simple and then I improved its visuality.intouch attracted me so much when I started to learn day by day. After all these, the most funny part of the project was moving the cars with respect to the scenario because I really like programming. REFERENCES Page 23
