Re: Not able to ignore SART alarm.

hasse/Thomas...

On the AIS SART alert ignore question:

Using the attached recording found earlier in this thread...

1. I find that if the Alert is active, i can then edit the options->ships->mmsi mprops to "ignore" this target. Then close the options dialog. Then "Acknowledge" the SART alert one more time, and no further alerts will be seen. Also, if I restart OCPN, I never get alerts for this target again.

Is this consistent with your observations? If not, how so?

Thanks
Dave

Thomas/hasse...

Lets be ultra-clear here.

Does the function work as described for you?

@Rick...
Thanks for documenting so clearly. Looks good.

Thanks
Dave

Well, when I run the test recording of a SART alert it is not enough to set the MMSI number to ignore and then acknowledge the alarm. After a while it turns up again.

Here is a link to a video I recorded.

Re: Not able to ignore SART alarm.

hasse_A...

Thanks for the video. Very clear.

Question:
If you save the MMSI Properties to "ignore" for the SART target, and then close and re-open OCPN, is the MMSI->ignore setting retained? And do you get SART alerts in this case while playing the recording after a restart?

Thanks
Dave

Re: Not able to ignore SART alarm.

hasse_A...

I reproduced the specific case shown in your video. This only happens within the running OCPN session in which you actually set the "ignore" flag. We get a "phantom" alert on the target, since he is in the "acknowledged-but-still-active" target queue. However, subsequent restarts of OCPN honor the specification, and we never see that SART alert again.

Anyway, I have corrected the specific corner case shown, will be seen in the next Beta Release.

Thanks for your patience in digging this one out of the noise.

Re: Not able to ignore SART alarm.

Dave,

I am uncomfortable permanently ignoring a MMSI. Especially one that is associated with an AIS or DSC emergency or safety message.

One possible method of handling these message would be to display an ICON that flashes red when an ignored MMSI message is received. Clicking on the ICON would pop-up a list of the last 10 (or less) ignored MMSI's received. Clicking on a MMSI would reactivate it and close the pop-up.

I have the contrary opinion. I hate software that has built into them "intelligence" that is supposed to be smarter than the user and you cant control.

If you do set a SART or whatever to ignore, you probably have a good reason to do so and you should of course be aware that it will be ignored in the future.

If you are uncomfortable with this then don't set the ignore attribute.

This is also a good incitement for people to be careful not to let their alarms go of without an emergency situation.

Hans,

As much as we might desire it -- it is not possible to control every detail of the world around us. Unintended events will occur that we wish didn't.

Imagine that a boat is placed on the hard for a bottom job -- somehow the boats SART device is activated -- you detect a land based SART and set it to be ignored -- a week later the boats owner returns to find a note that his SART was on -- sometime later the boat has an emergency and the SART is activated for real -- you are only a few miles away and in a position to assist -- however you are still ignoring his MMSI -- and people die!!!!

This to me is immoral and totally unacceptable. And, although I don't know you, I will assume that this would not be the out come that you would desire.

This is not about the software being smarter then the user. It is about giving the user the opportunity to do the right thing.

Paul

Thanks. Dave

Sorry, the result was what is written in the wiki, but then there were the lingering ais sart artifacts, which I wondered about, and you and hasse now have fixed. Thanks!

I respect you view. But, sometimes you have to accept the less of 2 evils. What is less evil of your case and the following ?

You are out sailing and there is a boat on the hard where its SART has gone of and the alarm comes popping up your face every 10 seconds so you are unable to navigate using the plotter. What do you do ? You probably turn off the AIS all together. Now the alarms are silent and so are all other targets including not only the SART from the boat on the hard but all other SARTs from any other boat in distress and all AIS targets from all other boats.

I consider the first case (your case) to be much less evil as the risk of you being the closest boat when this one boat after it is launched gets into a distress situation and its only ability to get a message out is via its SART that now probably also is low on battery is very low.

False alarms are serious and should be recognized.
We walked over to the yard where the false alarm came from but there were so many boats on the hard there it was impossible to pinpoint which one it was. We informed the yard personal but they didn't seem to care. What do you do then ? Call the Rescue Center and inform them that there is a boat in distress ? We emailed them but got no response. So what more should we have done? We could have relayed a Mayday over channel 16 but that would have been to much and probably misuse of Mayday as it was a false alarm, or was it? It could be someone on board having a hart attack and was only able to reach the SART and sett it of. Who knows ? At Chaguaramas we seemed to be the only ones trying to alert the situation but nobody else cared.
