Guard Zone Alarm repeats too often

[NAHANNIV]

This makes it difficult to do anything with the RADAR while there is a target in the gaurd zone, including turning off the gaurd zone.

Possible soloutinons:

• different window.
• option to turn off gaurd zone from the alarm window.

The second option sounds good. I'm not convinced of the first. When used to this new behavior it's rather handy even though my first impression was like yours.

BTW: Kees, pls recover saving radar menus last position. That function was recently lost.

Yeah, I really don't like multiple windows. Especially when they decide they want to be"under" the chart window. BTW: Kees, pls recover saving radar menus last position. That function was recently lost

Please do not merge issues, this makes it hard to close them.

New issue opened for radar menu

[keesverruijt]

On the original issue, I don't understand. If you confirm the alarm, it doesn't raise again and I can continue using the menu.

Please give me more detailed steps for what your exact issue is if pressing Confirm doesn't fix it for you.

Testing at my slip today with many boats entering/exiting the chanel. After confirming the alarm sometimes the alarm would be raised repeatedly while I tried to navigate back to the gaurd zone menu.

[keesverruijt]

The “confirmation” resets when the guard zone becomes empty:

if (bogeys_found) { if (!m_guard_bogey_confirmed && TIMED_OUT(now, m_alarm_sound_timeout)) { // If the last time is 10 seconds ago we ping a sound, unless the user // confirmed m_alarm_sound_timeout = now + ALARM_TIMEOUT;

  if (!m_settings.alert_audio_file.IsEmpty()) {
    PlugInPlaySound(m_settings.alert_audio_file);
  } else {
    wxBell();
  }
}

} else { m_guard_bogey_confirmed = false; // Reset for next time we see bogeys }

so if you have an ultra small guard zone and the boat leaves then the confirmation needs to be made again. Maybe there should be a timeout on this so that a confirmation still holds for a number of seconds after you confirmed.

[Hakansv]

Ok - I'm convinced. Either let the first "confirm" shut all alarms for a while or add your second option; a button to set all alarms off or move the alarm box out of radar menu

[NAHANNIV]

Yes the zone was quite small with lots of traffic. Perhaps this is not a valid test? But it was annoying!

[keesverruijt]

Fixed it I think. No traffic in sight here right now, and I need to go to bed.

[NAHANNIV]

Sorry, I have no way to simulate this and won't see the live situation till next weekend.

Here is my crazy idea; (sorry to bring this up in a bugfix issue, but it is related to the problem)

Don't make alarms that produce anything that needs to be confirmed or reset to keep normal operation of a navigation system. Ever. For any reason. Many professional manufacturers have managed to make their alarms unusable and dangerous this way, just look at Raymarines AIS alarms on the E-series. Useless.

An alarm should be visible but not intrusive. There is no way to know that this alarm is the most important thing for the mariner in that exact time.

If I remember correctly, disruptive alarms are not allowed in the ECDIS standard, and for a good reason.

If we see this as purely a "I am on a crossing without a boat in sight and need to take a nap" kind of alarm, OK, I can turn it off and never use it. But that would be a pity because it could be very useful in other situations as well.

Ideally, there could be 3 levels to select from

1. Off
2. Normal
3. Audible
4. Intrusive

Normal alarm should be visual only, for example the target becomes red and/or flashes, and/or guard zone flashes. Corresponding to the ECDIS standard for dangerous AIS targets. Audible should be like normal but with a single sound when this state occurs Intrusive should be like we discuss now, something you cant get to shut up without confirming....

I don’t think it is crazy at all, in fact I fully agree. Dunno whether we can make this for 2.0.0.

Can you find out what the ECDIS standard for this is precisely?

Will try to find relevant parts tonight. I mainly studied the AIS parts earlier.

[keesverruijt]

I put your suggestion in a new enhancement request, see issue #165.

[NAHANNIV]

Sorry it took so long to get back to testing this, we are now aboard full time.

Trying to test this today, but there seems to be a problem: as I am setting it up (still entering the parameters) the guard zone alarm comes up for a second then off for a second, then repeats.

Once setup, some geese swimming in the harbor provided a moving variable target that also caused the alarm to be raised too often.

[keesverruijt]

I've been working on this today, see today's commits.

It works to my satisfaction now.

There is a new option on the options/preferences dialog that allows you to set the repetition of how soon the alarm goes off again. Setting it to 0 will disable audible alarm.

Please reopen this issue if you still get the fast repetition of the guard zone alarm coming up. It should be fixed now.
