Start Probleme

Bernard · Jul 21, 2023

There is 1.62v on teensy pin 23 and 2.4v com from lm386

It's OK , so the resistor are correctly soldered.
But the result is very strange.
Change the resistor on the perimeter wire to have more than 600ma in the sender sense and Test with new LM386 and coil from shop.

Da habe ich 35 ohm zwischen den beiden!?

Wenn ich mich nicht irre, müssten es 10kohm sein... Hast du mal am Poti in die andere Richtung gedreht?
Gegen den Uhrzeigersinn muss er gedreht werden, also links herum!

Ja ist ganz nach links Anschlag, das sollte, volle Leistung sein! Na ich müsste heut ein neues Modul bekommen da werd ich mal sehen ob es anders ist.

Hallo,
so also der neue Empfänger und die spule bringt schon mal andere und bessere werte. Aber ich bekomme keine richtigen mA aus meinem Sender herausgekizzelt. Es sind nach wie vor nur 0.97 mA verbrauch bei 100m Draht, vom Sender zum Motortreiber für den Draht. Das ist doch viel zu wenig oder? Ist das evtl. Ungünstig das der draht zum großen teil noch auf Rolle ist!?

Hello, so the new receiver and the coil bring different and better values. But I'm not getting any real mA out of my transmitter. It is still only 0.97 mA consumption for 100m of wire, from the transmitter to the motor driver for the wire. That's way too little, isn't it? Is it possibly unfavorable that most of the wire is still on a roll!?

Heut auch wieder einen kleinen testaufbau im Garten gemacht. mit der Funktion "Lane" fuhr er eigentl. Eine Weile schön in dem Bereich abgespeckten bereich herum. Aber bei "Wire" zum beispiel, hört er relativ schnell auf mit folgender Meldung POBSCIRC!? BEI Rand mit PTRK!?
Gibt es da eine Anleitung woe mann da am besten herangeht? Er hört meistens auf das der buzzer schellt und ich habe keine Ahnung was los ist!?

Today also made a small test setup in the garden. with the function "Lane" he actually drove. A while nice in the area slimmed down area around. But with "Wire" for example, it stops relatively quickly with the following message POBSCIRC!? AT edge with PTRK!? Is there a guide on how to best approach it? He usually listens to the buzzer ringing and I have no idea what's going on!?

I don't see the wire load resistor ?
Maybe you forget it : Something like that :

Mit dem Multimeter habe ich nie nachgemessen. Ist ja auch eher eine Rechteckspannung. Weiss nicht ob du da vielleicht doch im Wechselstrom Bereich messen musst? Was sagt denn das INA Modul?

POBSIRC bedeutet dass ein Hinderniss im Weg war und dass möchte der Mäher dann umfahren. Hinderniss kann z.B. durch den Bumper erkannt werden, aber auch durch den Motorstrom. Die Ausgabe der Console sollte da weitere Infos liefern.

PTRK bedeutet dass der Mäher dem Perimeterdraht folgt...? Das sollte nur bei start aus der Station heraus kommen, denn nach dem Ausparken fährt der Mäher eine definierte Strecke auf dem Perimeterdraht und fängt dann an zu mähen.

I never checked with the multimeter. It's a square wave. Don't know if you might have to measure in the AC range? How much mA the INA module say? POBSIRC means that there was an obstacle in the way and the mower wants to avoid it. Obstacles can be detected e.g. by the bumper, but also by the motor current. The console output should provide more information. PTRK means the mower follows the perimeter wire...? This should only happen when you start out of the station, because after the Stationstart the mower drives a defined distance on the perimeter wire and then starts mowing.

Der aufgewickelte Draht auf der Rolle ist mit Sicherheit nicht hilfreich, hast du nicht 20 Meter Kabel die du zum testen nehmen kannst?

Oh yes, here is the little Monster 12ohm 50w.

Hast du mal versucht die 2. Schleife in Betrieb zu nehmen? Vielleicht liegt ein defekt am Ausgang der A-Schleife vor?

Have you tried to activate the 2nd loop? Perhaps there is a defect at the output of the first loop?

Vielen Dank Stefan, wo kann mann das denn nachlesen!? Ich sehe immer irgendwelche meldung und Abkürzungen, kann aber nichts damit anfangen.
Na gemessen habe ich das was der ina theoretisch auch misst den Gleichstrom der zum Motortreiber geht. Das müsste ja noch ein ganz normaler Stromkreis sein.!?

If you have a scope :
here what you need to see at the output of the L298N whithout the resistor and wire: (+ or -9V) with the sigcode

And at the receiver. Mag value are for arduino DUE ,for teensy it's near 10 or 15000

On sender If you have a 12 Ohm resistor , and 9V on DC/DC you need to read near 9/12= 0.75A
0.98mA tell you that the sender is not working.

No, unfortunately I haven't, but the driver should send 9v to the line? With me it only sends 5v to the wire at 10V input!?
I will try the lm!

Nein habe ich leider nicht, aber der treiber sollte 9v auf die Leitung schicken? Bei mir schickt er nur 5v auf den Draht bei 10V eingang!?

Bernard · Jul 23, 2023

No, unfortunately I haven't, but the driver should send 9v to the line? With me it only sends 5v to the wire at 10V input!?

Your multimeter can't mesure the high frequency signal and the 5V result is certainly a rounded value of the frequency (+10,-10V)
In all case your multimeter into Sense mode is perfect to see what's append in the wire and you need to see more than 0.98mA certainly 750mA

Can you share the code you use on the sender ?

Es ist ein Wechselstrom Schaltkreis mit unregelmäßiger Rechteckspannung. Das geht in Richtung Frequenztechnik und das ist ziemlich kompliziert. Die Wirkweise der Ardumower - Perimeterschleife kann man gut nachlesen.

On the console you can see the STATUS / STATE of the mower over time and some text on what's append .

For example in your console:

Mower is in station and wait (no charging) --> STATION / STAT
You click on start so:
manual start from station
start sender1 ( a wifi command is send by the mower to sender
stop sender2
stop sender3
NORMALMOWING/STARTSTATION -->STATE_START_FROM_STATION, //when mower is station and a start command is receive need to start again IMU ,perimeter signal etc.... and wait 3s
IMU heading is reset
station reverse (mower reverse for x meter)
station rol (mower rol for y degre)
Now the mower check if the sender work and try to read the signal but fail because detect mower is outside.( Mag is >0 and need a negative value)
ERROR No SIGNAL SmoothMagnitude =5147.00

SO try to put mower inside the perimeter and check if Mag left is negative,: If it's positive invert the 2 perimeter wire at the output of the sender.
