6 storey elevator

Hi,

I'm newbie about programming microcontrollers and I have to make a program with PIC that command a six floors elevator

If anybody can help me, I'll be very grateful


THX in advance
 

Re: 6 storey elevator

First of all, elevator control is very specialized. I hope you get liability insurance as well!

Secondly, please define the scope of your project. Are you working on sending commands from each floor or only the main control? In most cases, the console (usually 2 butttons UP/DOWN and a display showing position) on each floor is controlled by a serial bus from the main controller. The main controller is the one which decides the motion based on the floor number the elevator in on and from the requests from either inside the elevator or from the floors. This logic is relatively simple. You have a list of floors you need to stop at, you know the starting point and you go in a serial order.

The main complexity comes from the safety features: For example, the logic for door opening is tied to the limit switches on the floors. Moreover, the design to do acceleration and decel depends on the weight of the elevator and other things like whether you are using a two speed motor or a variable frequency drive and so on.

Please be careful in the hardware as well since the elevator (due to bundling of cables and the presence of AC drives, contactors) is highly noisy area. The last thing you want is a poorly designed hardware which hangs when, say, a door opens/closes and you are stuck inside.

Re: 6 storey elevator

Hi, thank you for answering ...

Only I am working in the elevator's main controller ( for the moment ), that is in the logic of the movement in the floor that the elevator be called either from within the elevator or from the floors.

The doors's logic is going to be following step, and after the velocity, acceleration and deceleration, etc.

Any helps or suggestion will be very received as far as I am concerned, either with the programming of the microcontroller ( preferentially a PIC ) or some comment.

Thanks in advance
