2、rnal of Robotics and Automation (IJRA)Vol. 4, No. 3, September 2017, pp. 202~208 (如覺得年份太老,可改為近2 年,畢竟很多畢業(yè)生都這樣做)英文 1984 單詞,12175 字符(字符就是印刷符),中文 3102 漢字。PLC based Multi-Floor Elevator Control SystemABSTRACT:This paper prese

3、nts programmable logic controller based elevator control system. Primary focus is on using programmable logic controller to build the elevator model. To control the motion of the elevator through various levels DC geared

4、 motor is used. Push buttons are used to give signal to the elevator to come to the desired floor, traversing up and down. Moreover DC relays are used as switches, not protective devices, to drive the motor in clockwise

5、and anticlockwise direction. Ladder logic is used for the model implementation.Keyword: DC Geared Motor, DC Relay, Ladder Diagram, PLC-Elevator Interfacing ,Programmable Logic Controller (PLC),Switched Mode Power Supply

6、(SMPS)1. INTRODUCTIONDue to rapid population growth in cities and presence of multi-storied buildings, the 2.DESIGN AND CONSTRUCTION OF SOFTWARE AND HARDWARE MODELThe project includes the design of the ladder diagram on

7、a software installed on the computer. It is downloaded to the PLC, and connected via communication interface. It also includes the interfacing of various hardware devices which are discussed in the sections below.2.1Soft

8、ware ModelThis section discusses about the development of ladder logic diagram. The relevant PLC has been incorporated based on the requirements of the logic. Here RS Logix 500 has been incorporated to develop and downlo

9、ad ladder logic to the PLC. The program is divided into two parts, upward traversal of the elevator and downward traversal of the elevator. Each part is divided into three cases, one floor traversal, two floor traversal

10、and three floor traversal. A counter is used to indicate the floor on which the elevator is currently present. Table 1 shows the input address and counter value corresponding to floor number.The ladder diagram includes t

11、he equality block, which will work only when the accumulator value of the counter, here represented as C5:0.ACC, equals the user defined integer value. Six timers have been used, three in upward motion and three in downw

12、ard motion of elevator. The Timer Timing bit (TT bit) is used to run the motor. Output address O:0/0 and O:0/1 are used for the upward and downward motion of motor respectively.2.1.1. Upward MotionFig.2, fig.3 and fig.4
