Alarms are located on the left side <br clear="none" />under the yellow/black warning graphic. Each one functions as both an <br clear="none" />alert and alarm. For example, a yellow alert lights up "DEPTH" at 500 <br clear="none" />feet to warn of approaching maximum depth. At 600 feet it turns into a <br clear="none" />red alarm. These alerts and alarms can only be disengaged by retreating <br clear="none" />back to a non-alarm operating environment (ie.. decreasing depth to less <br clear="none" />than 500 feet). Audio alerts will accompany the visual ones.<br clear="none" /><br clear="none" />Depth is available on all displays in the lower left corner. Data <br clear="none" />logging is included and can be written to a USB drive and 'replayed' on <br clear="none" />any other computer that has the same software on it or even imported <br clear="none"
/>into something like a spreadsheet. However, if I end up with a tablet I <br clear="none" />will likely log there directly.<br clear="none" /><br clear="none" />Battery information will be added when I get those sensors. This design lends itself well to semi-automated control, for example typing in a <br clear="none" />target depth of 100 feet and then letting the computer operate the <br clear="none" />motors and monitor vertical rate of descent/ascent, slow down when <br clear="none" />approaching the target depth, and then shutting off the motors at/near <br clear="none" />target depth.<br clear="none" /><br clear="none" />A more distant and advanced project would be, I don't know, maybe <br clear="none" />inertial navigation using an IMU.<br clear="none" /><br clear="none" />Jon<br clear="none" /><br clear="none" /><br clear="none" />On 8/10/2015 12:19 PM, Cliff Redus via Personal_Submersibles wrote:<br clear="none" /></pre><blockquote class="yiv4489432602gmail_quote"
style="margin:0pt 0pt 1ex 0.8ex;border-left:1px solid #729fcf;padding-left:1ex;"> Jon, your first pass at HMI for your boat looks good. I like the <br clear="none" /> overall layout and data seems to be presented in logical and <br clear="none" /> straightforward manner. I think it would easy for someone other than <br clear="none" /> yourself to get the state of the boat from this HMI.<br clear="none" /><br clear="none" /> On your DIVE panel, I would add a couple of items. !
The
first is the <br clear="none" /> battery SOC and air SOF(state of Fill, 0-100%). These are key <br clear="none" /> items for the home screen. Also, I would add a proximity switch on <br clear="none" /> hatch so that the hatch state is shown. This can also be used to <br clear="none" /> lockout diving the boat unless the hatch switch is closed. Also I <br clear="none" /> would add Altitude. Airmar has a sensor called the DST800 that gives <br clear="none" /> boat speed, depth (altitude) and water temperature. Signals comes in <br clear="none" /> as a RS-232 ASCII string that you parse. On the NAV screen, I would <br clear="none" /> include depth and altitude. On HIST screen, rather than looking at <br clear="none" /> min and max on key variable's, I would recommend that up set up data <br clear="none" /> logging and log all ship systems say every minute. Most PLCs and <br clear="none" /> associated HMIs have data logging capabilities. This allows you to <br clear="none" />
download all sensor measurements and switch states as a function of <br clear="none" /> time. This is useful to analyze how the boat performed after the dive <br clear="none" /> and
also serves a Black Box for the sub. I did not see any alarm <br clear="none" /> database. Need to be able to see and hear and audible alarms an such <br clear="none" /> items as low air pressure, O2 and CO2 out of range ...<br clear="none" /><br clear="none" /> Best regards<br clear="none" /><br clear="none" /> Cliff</blockquote><br clear="none" /><br clear="none" /><br clear="none" /><hr /><br clear="none" />Personal_Submersibles mailing list<br clear="none" />Personal_Submersibles@psubs.org<br clear="none" /><a rel="nofollow" shape="rect" target="_blank" href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br clear="none" /></blockquote></div></div></div></div><br /><div class="yqt5057109605" id="yqtfd42472">_______________________________________________<br clear="none" />Personal_Submersibles mailing list<br clear="none" /><a shape="rect" ymailto="mailto:Personal_Submersibles@psubs.org"
