Wetterstation: Davis Vantage in IPS direkt einbinden?

Archiv Allgemeine Diskussion (2.x/3.x)

nancilla, ich denke es ist zweckmässioger, das Datenpaket mit PHP-Befehlen zu parsen, weil es sind gut 30 meteorologischen Daten darin enthalten - ich müsste viele Cutters dafür anlegen, oder sehe ich das falsch?

22

Es wird doch bestimmt ein Start o. Stop-Byte oder beides gesendet und du willst die Daten (Block), die dazwischen liegen. Genau das macht der Cutter, indem du diese immer mitgesendeten Bytes auswertest und nur den wichtigen Teil der Daten an die Registervariable (im Ganzen) übergibst.

23

besten dank. geschafft! Deine Anleitung mit dem Cutter war entscheidend. Mir sind aber noch ein Paar Dinge unklar:

[ul]
[li]wenn ich eine HEX-Sequenz als Trennung Links im Cutter angebe, wird die links liegen gelassen oder kommt sie rechts mit?
[/li][li]was ist die beste Funktion, um eine HEX-Abfolge in Einzelteile zu zerlegen? Ich habe experimentiert mit intval(substr($DataStringHex,0,2)) ohne grossen erfolg…
[/li][/ul]

Es ist mir bewusst, dass diese Dinge relativ elementar sind, und ich bin für das Händchenhalten sehr dankbar. Im Gegenzug werde ich das Gesamtskript verfügbar machen, so dass andere Davis-Besitzer sich daran bedienen können.

zu 1. - Rechts
zu 2. Wie kommen denn die „Teile“ nun an?

25

bin fast so weit. gewisse Werte (feuchtigkeit) werden mit einem byte repräsentiert, und die kann ich aus dem Datenpaket isolieren mit z.B. $outsideHumidity =hexdec(strtohex(substr($DataStringHex,33,1)));. In letzterem Falle ist es Byte #33, welches ein dezimales Prozenzwert der Feuchtigkeit wiedergibt. Das funktioniert nun gut - was schon mal prima ist.

Was ich nicht weiss ist, wie ich 2-byte Werte konvertieren soll. Z.B. der Luftdruck wird angegeben mit 2 Bytes an Stelle #7 und #8 des Datenpakets aber der Befehl $barometer = hexdec(strtohex(substr($DataStringHex,7,2))); führt zu komplett absurden Werten. Kann jemand Abhilfe schaffen?

26

hier ist der gegenwärtige Zustand des Skripts, zur Veranschaulichung (mir wird sonst immer vorgeworfen, ich sei unspezifisch). Ich würde aber niemandem raten, diesen „work in progress“ in sein IPS einzubinden. Die Aussentemperatur liegt laut Skript derzeit bei 3567 °F Grad Fahrenheit…

Ich versteh deine Umrechnerrei nicht. Die Daten kommen doch als Hex an oder nicht.

Kannst Du mal einen Dump von Comport, Cutter und Registervariable anhängen.

28

danke, Rainer. Ich bin sicher, dass ich etwas Dummes mache - aber ich weiss nicht was!

Here we go. Ich habe die ersten 2 bytes der Registervariable mit „LO“ programmatisch gepatcht, damit die Länge mit den Spezifikationen von Davis (s.o.) nach der Cutter-Intervention wieder stimmt:

Mit anhängen, meinte ich auch anhängen als Datei. Damit kann man auch arbeiten. :wink:

In solchen Fällen wird das niederwertige Byte meistens zuerst gesendet. Du mußt die Bytes erst drehen und dann zusammenrechenen. Dann kommen auch sinnvolle Werte raus.

wow!!! Darauf wäre ich NIE IM LEBEN gekommen! Ausprobiert (zunächst für die Temperatur), und siehe da, 86.3 Fahrenheit. Im Serverschrank, wo die Davis erstmals plaziert ist, scheint das ein realistischer Wert zu sein. VIELEN HERZLICHEN DANK!

Bleibt dennoch das Problem mit den „signed bytes“. Bei Offset 3 gibt es folgendes:


//    "P" (Rev A), Bar Trend (Rev B)  3       1       Signed byte that indicates the current 3-hour barometer trend. It is one of these values: 
//                                                    -60 = Falling Rapidly  = 196 (as an unsigned byte) 
//                                                    -20 = Falling Slowly   = 236 (as an unsigned byte)   
//                                                    0 = Steady  
//                                                    20 = Rising Slowly  
//                                                    60 = Rising Rapidly

Ich kriege nur positive Werte heraus - wäre aber ganz nett, -60 anstelle von +196 zu bekommen. Wie kriege ich das hin?

32

Werte ersetzen, wäre zu trivial oder?

Da lese ich noch in der Protokollbeschreibung:

There are two different loop data formats. Rev „A“ firmware, dated before April 24, 2002 uses
the old format. Rev „B“ firmware, dated on or after April 24, 2002 uses the new format. The only
difference between these formats is the inclusion of the current 3 hour barometer trend in place
of the fixed value „P“ in the fourth byte of the data packet.

Welche Firmware hast du denn auf dem Gerät?

33

Ersetzen würde zwar gehen für diese 3 Werte, aber (1) es ist nicht elegant und (2) es hilft nicht Anderen als Referenzlösung, welche ähnliche Probleme haben;

Ausserdem (3) hätte ich eventuell das gleiche Problem bei der Temperatur. die Werte stimmen jetzt zwar. Aber wenn es unter 0°F kalt wird, weiss ich nicht was die Station hergibt.

0°F ist ca. -18°C- Das ist zwar heftig und kommt nicht häufig vor im Eidgenössischen Unterland - aber die Wetterstation soll gerade bei Extremwetter keinen Spuk von sich geben…

Meine Version gibt schon den Dreistunden-Trend aus. Kann man notfalls über PhP auch rekonstruieren, aber warum in die Ferne schweifen wenn die Station das schon liefert…

34

Wie wär’s wenn du nochmal dein derzeitiges Script dazu „blank“ ziehst? :smiley:

35

Hallo,

das Vorzeichen ist im Bit 7 des Bytes. Dies wäre eine Möglichkeit es umzusetzen:

$barTrend =  hexdec(strtohex(substr($DataStringHex,3,1)));
$barTrend = $barTrend - 256 * ($barTrend >> 7);

Attain, you da man! Und natürlich klappt es bestens nach Deiner Anleitung. Falls Du einmal einen Kurs „Grundlagen der Informatik für alternde Molekularbiologen“ veranstaltest, werde ich mich sicher einschreiben!

Hi @ All,

geht das auch ohne einen Virtuellen Com-Port und wenn nicht mit welchem soll ich das machen ??
Meine Vantage Pro2 läuft mit Datenlogger und USB und wird auf COM3 erkannt. Würde gerne dieses Script einbinden
komme aber Ihrgend wie nicht weiter. :confused:

Hallo Ralf,

schau mal hier.

aag hat bei seiner Beschreibung nur den Cutter vergessen.

Das geht natürlich auch direkt.

Hallo Frank,

das mit dem Cutter habe ich nur das mit dem Virtuellen Port raffe ich nicht und oder wie Funzt das mit direktem ansprechen des ComPort3 an dem die VPro dargestellt wird ob wohl sie per USB am IPS Server angeschlossenn ist.

Habe ziemlich lange Pause gemacht und stehe irgend wie wieder am Anfang :frowning:

Grüße Ralf
