$250-750 USD

Paid on delivery
1)To design a driver that decodes elevator position from different types of elevator controllers(binary,inverted binary), and sends that information serially with the minimum amount of wires possible(must be able to supply 40 units) ALL inputs will be universal to +24 to +48vdc/-24vac to -48vdc/120vac/240vac -0000000-1000000 latched inputs -Door open limit input -travel up input -travel down input -8 optional scrolling message inputs 2)To design a board that can be used universally on any elevator landing that decodes this information into a color screen with the floor indication. The screen will be able to display a 3 digit number and/or letters. This screen will show current floor and car travel direction. Each board will be addressable with dip switches. The arrival light will light when door open limit is active on driver and addressed board matches binary input on driver 3) there will be 8 preset optional text messages to be displayed (to coincide with the 8 inputs on driver)for example:overload, inspection, independent service, out of service, help on way 4) optional arrival gong speaker for future 5) graphic digital pattern of lantern must be able to update along with preset scrolling message

Summary your idea first. You need to make two devices: (1) Get inputs from elevator controllers and extract information such as floor position, door status, travel direction, custom messages, etc and then send necessary information over serial wires to devices (2) (2) Display devices that get information from device (1) and show appropriate data to users such as floor, travel direction, arrival light, etc. The device have some ways to set address, set display data. Those are the big picture of the systems. Detail of number of inputs, outputs, meaning of each, etc need specify after detail discussion. If my above understanding is correct, you can get full support to have that devices. As 12-years embedded design engineers, I can design circuit, make prototype, developing firmware, testing until you have a working system. And the circuit is an industrial grade design with fuse, circuit protection, etc. It's definitely not a hobby design. Please have a technical discussion to see how can we make it. The money bidding is just for reference, we can adjust later after understanding the technical side fully. Basically, you're always pay after receiving work.
