Recommendations of the fencing event

[huangpeizhi]

Hi, @tidwall

In the fencing event, each ENTER and EXIT are belong to the same group, you can consider adding a unique identity in the event of recognition?
This can be avoided, while many fences ENTER/EXIT after the information storage, sorted in order to know each Member of the Group

thanks!

In the fencing event, each ENTER and EXIT are belong to the same group, you can consider adding a unique identity in the event of recognition?

I can add a unique event_id for each message such as:

{
  "command":"set",
  "detect":"enter",
  "key":"fleet",
  "id":"bus1",
  "event_id":"8aa68be86f92512a0d7c6804",
  ...
}

Would this be helpful?

I want is a set of events that are associated with the identification , in determining the entity in and out of the fence, the ENTER/EXIT event is associated.

[huangpeizhi]

what is it combined of event_id?

[tidwall]

Sorry for the delayed response.

I think I understand now. So you would like to have your messages grouped by the "enter"/"exit" events?

Perhaps something like this:

{"group_id":"8aa68be86f92","key":"fleet","id":"bus1","detect":"enter",...}
{"group_id":"8aa68be86f92","key":"fleet","id":"bus1","detect":"inside",...}
{"group_id":"8aa68be86f92","key":"fleet","id":"bus1","detect":"inside",...}
{"group_id":"8aa68be86f92","key":"fleet","id":"bus1","detect":"exit",...}

{"group_id":"75a3ef68cc15","key":"fleet","id":"bus1","detect":"enter",...}
{"group_id":"75a3ef68cc15","key":"fleet","id":"bus1","detect":"inside",...}
{"group_id":"75a3ef68cc15","key":"fleet","id":"bus1","detect":"inside",...}
{"group_id":"75a3ef68cc15","key":"fleet","id":"bus1","detect":"exit",...}

This is a good idea and I think that it's possible, but I'll need to dig a little deeper before making promises.

[huangpeizhi]

Yes, it is.
Because, in practice, many in/out is does not meet the requirements and need to remove certain conditions.

Hi, @tidwall

Note the same machine multiple tile38 process，tile38 can't produce the same group_id，can refer to mongodb objectid.

[tidwall]

I just pushed a build to master that groups with the key "group" and uses the BSON ObjectID format.

Let me know if this works for you.

[huangpeizhi]

@tidwall,

Thank you very much, I've put the GROUPID in database, inspection data.

[tidwall]

That's great to hear. Let me know if there's anything you need.

@tidwall ,
Running one day, no problem, i close the issue, if problems are found, then reopen.

thanks!
