How often does it return to the base station? What is the required latency of the rundown information?
You charge it once per shift, and you need an update every minute.
The dumb problem exists because of very real limitations.
- fluoridation 3y agoEvery minute? What possible use could such granular information have?
- inhumantsar 3y agofrom the article: "allows engineers to tighten bolts and other mechanical fastenings to precise torque levels that are critical for safety and reliability." high precision factory gear in safety-critical applications seems like a reasonable use case to me.
- fluoridation 3y agoThe tightening is done by sensors inside the tool. That has nothing to do with any kind of tracking or with anything that happens across a network connection.
- daveguy 3y agoBut tracking tool health in safety-critical applications (think bolt torque on an airplane door plug) could benefit from automated tracking. Generally this is solved by regular inspections and calibration, which is cheaper and avoids the security issue. There is some benefit to automated tracking and fault identification. Doing it on an air gapped network means you have to be on site to check status and errors, which seems reasonable to me.
- fluoridation 3y agoAnd tracking tool health is something that precisely doesn't need to be done on a minute-by-minute basis. Doing it once at the end of every shift seems more than enough.
- csours 3y agoSorry customer, your quality tracking system is dumb. Sorry sales team, your customer is dumb. --- The previous step must be completed successfully before proceeding to the next step. A system records this information for posterity.
- Closi 3y agoWell it could be every few miliseconds. Sometimes these sort of screwdrivers can drive other processes (e.g. once it confirms that the screw is correctly affixed, send a message to the manufacturing system to tick off that 'task' as complete at this station, and prompt the operative to start the next assembly task - the piece cannot move to the next manufacturing process until the screwdriver has confirmed all bolts are affixed at the right settings).
