Which microcontroller is used in elevator?
ATmega8 microcontroller
We use ATmega8 microcontroller and IR sensor module to design the elevator system. Movement of elevator is done with the help of DC gear motor which is controlled by motor driver IC(L293D).
Does an elevator have a microcontroller?
Elevator, is a transport device which is very common to us in present days. In this project, Atmega8 microcontroller is used as the primary controller and it consist of various inputs and outputs circuits together with a lift model.
What is an elevator controller?
An Elevator controller is a system to control the elevators, either manual or automatic. The low voltage power supply is for the controlling component and the fixtures to control the elevator (except the items mentioned above, they use the single phase power supply.).
Where is the elevator controller located?
Since the elevator controller is usually located at the uppermost storey of the building, a smoke detector at the top of the elevator shaft is considered to meet the intent of Clause 3.2.
How do elevator control systems work?
As this elevator system uses a roped mechanism, the elevator engine is connected to a sheave which the ropes are looped around. The controller interacts with the elevator engine by sending it a signal that specifies at which speed and in what direction the engine should be going in.
What types of elevator operating systems are available?
there are 3 main types for elevator control systems as follows:
- Single Automatic operation: First automated system w/o single call button on each floor and single button for each floor inside car.
- Selective collective operation:
- Group automatic operation:
What are the four types of elevators?
The modern elevators come in four main types: hydraulic, traction, machine-room-less, and vacuum.
- Hydraulic. Pistons for support are usually placed at the bottom to push the elevator car up while the hydraulic fluid is forced down by the electric motor.
- Traction.
- Machine-Room-Less.
- Vacuum.
Why we designed microcontroller based elevator system?
Most elevator system implemented in our country are controlled by using PLC (programmable logic controller), but these control system is very expensive. So we designed microcontroller based elevator to minimize the cost of elevator and to provide elevator to customer with minimum cost.
What is ATmega8 microcontroller based lift system?
In our project, the atmega8 microcontroller based lift system is constructed to simulate as an actual lift in the human life. The elevator control system is one of the important aspects in electronics control module in automotive application. Here elevator control system is designed with different levels.
What is the working principle of the elevator?
Based on the elevator switch pressed, the elevator car is moved either in upward and downward direction. D.C. Motor is another important component of elevator system. Based on the switch pressed, the D.C. Motor either moves in forward and reverse direction to move the elevator in either upward or downward direction.
What is the output hardware of the stepper lift?
Stepper motor driver circuit, DC motor circuit, seven-segment display, buzzers and various types of LED (light emitting diodes) displays are used as output. The lift model was constructed to simulate an actual lift in the real life. It can be counted as the output hardware of the system.
