Hi,
Here is an interesting real-world problem that I wonder if anyone has already solved in a different context.
I'm a member of the Royal Aero Club Records Racing and Rally Association who are responsible for organising races between aircraft ("Air Races") in the UK. We recently had a very tragic accident where two aircraft had a mid-air collision because two aircraft were on top of each other and were hidden in each others blind spot.
So what we were thinking is would it be possible to design a fairly simple device that could detect other similar devices, and give some sort of warning if it detected another device within a given range. Ideally, we would like to be able to indicate (maybe by red, orange and green LEDs or similar) another unit within say 100m, 25m and 10m. There should probably be some sort of handshaking between the units, so we positively identify another aircraft.
We thought about maybe using the 3 modes of bluetooth with their different ranges connected to a PLC, so that when each of the 3 classes of signal was detected from another unit, an LED would flash. On looking at the complexity of Bluetooth, this seems like a sledgehammer to crack a walnut.
Does anybody have any better ideas of how to do this? If you've got circuit diagrams, so much the better!
thanks in advance.
