PLC Based Smart Elevator Control System Project
PLC Based Smart Elevator Control System Project report
The main requirement of all multi storage buildings are elevators. Elevators ease the work humans and keep him/her in the comfortable zone. Elevators are used in almost all the multi storage buildings in metropolitan cities. Elevators are nothing but the vertical transportation device which is used to transfer goods and passengers. Elevators use limit switch for floor indication. High rise buildings and malls constructions are widely increasing and elevator is an integral part of transportation medium in such infrastructures. By implementing plc-based smart elevator projects we can reduce the human efforts, accidents caused due to breakage of rope, efficiency and speed of elevator can also be improved. Even time can be consumed by using such plc-based elevator controller system. PLC controlled systems plays a vital role in stability and steady state of lift. It guides the lift in what order to stop at Floors, when to close and open the door. This plc based smart elevator control system project consists of three sensors, on each floor these three sensors senses the load in elevator. On pressing the start button twice, the elevator moves till the second floor. And the press stop button is used to stop the elevator. As the elevator passes through the respective floors, the colour of the lamp changes. Respective floor will be given respective colour lamp as the elevator reaches to the floor, the respective colour light lamp will glow.
Elevator is an importanttransport medium in multi-storage building. Withthe development ofbetterarchitecture technology,buildings areraising inheight.Hence an elevator becomes an importantmedium of vertical transportation. There are severaladvantages of an elevator in the modern world. Hencemore importance is given tothedesignofan elevator control system,which is easy for the maintenance and toperform an efficient function.Preliminarily, traditional elevator control systems work on the relay logic.More number of connectionsof relay logicare found in traditional elevator system. Hence it has becomedifficult to debug the failures in the system and also it is highly feasible job to facilitate alternateconnectionsto thefault tolerantsystems in the relay logic, where as in PLC based system,it is easy to debug the failures inthe system as it contains the simplelogics and easy maintenance.The mainobjectiveof this paper is toreplace the traditional relay logic elevator control system with the modern PLC based elevator controlsystem. The proposed work is tested withINDRA-WORKS ENGINEERING simulator and BOSCH-REXROTH PLC.
