An elevator is an electronic device that transports people or goods in a vertical motion. A microcontroller embedded in the control system of an elevator is used to control the elevator's mechanisms.
Yes, standard 8051 chips have plenty of I/O, their speed is comprehensive and the code size for an elevator controller don't have to be excessive. Check the local legal requirements if you want to use this in a live environment, additional (hardware) security measures may be required. You may wish to look into the PIC family of chips also. Very inexpensive, fast and easy to program and mass produce. Personally, I love these guys for a bunch of applications.
we can use both timers ...

When you press the button, a microswitch creates a circuit. That circuit sends a signal to the elevator controller, which is a computer that runs the elevator. Instantly, the controller powers the light inside the button, which is usually an LED. At the same time, the elevator is dispatched to your location based on a mathematical formula. Once the elevator arrives, the LEDs in the button are turned off. Buttons vary greatly, but a generally divided into vandal resistant or plastic. Vandal resistance is typically defined as a metal button that lands on solid metal when depressed. See www.epco.us for examples of many kinds of buttons.

microcontroller is a computer on a chip (IC) which contains processor which is programmed mainly by C language and used to control systems such as elevator, cars.... and so on.PIC is a type of microcontroller products from micochip company.
That depends on the specific microcontroller.

The PIC is a specific architecture of microcontroller.
The voltage of the 8031 microcontroller is 2.7V to 5.5V.
The 8051 Microcontroller is a microcontroller ("chip") developed by Intel in 1980.
PIC Microcontroller which means Peripheral Interface Controller. PIC Microcontroller is originally developed by General Instrument's Microelectronics Division.
Segger Microcontroller Systems was created in 1991.
to determine the state condition of microcontroller's input when microcontroller is reading the input port
The difference is base on the requirement of their0 application.
Microcontroller = (microprocessor+memory+peripherals) on a single chip
no it's not a microcontroller and lm 324 is quad low power comparator...
