HoistInsight System Design
There are two main modules comprising HoistInsight -- the Operator module and the Load module.
Both are very similar, except the Operator module connects to a smart/mobile device running the Hoist Manager software (the brains).
This module contains an EM-406 GPS device, an XBee-PRO 900 radio, an Arduino Pro Mini 328 and a mobile device of the operator's choosing. The XBee radio receives transmissions from the Load module that tell the operator where the load is in real time.
The load module contains the same GPS, XBee and Arduino, but has no need to connect to a mobile device. It simply relays it's position (from the GPS unit) back to the Operator module.
All of the "heavy lifting" is done in software running on the mobile device. Given the location of the Operator module and the Load module, the software can create lift plans and provide audible warnings when the load strays outside of the appropriate boundaries.
Currently the only licensed items are the Arduino librarys an 'Xaml Map' (used in the client application). I will strive to use the most open software available. My software, hardware and firmware will be released under the most permissive license available (haven't done the research at this point to determine what that is).
I would like to see this device on every crane operating at least in America. It WILL save lives and it WILL improve efficiency substantially. I would like for anyone interested in helping with this project to feel free to do just that. Everything I do will be 100% open.
I still need to design and fabricate the enclosures for both modules. I need to research and prototype sufficient rechargeable battery solutions that will last at least one shift.
I've already figured out all of the math and I've already figured out how to scale and orient structural drawings such that they are a huge benefit to the crane operators.
