Topic: AS3595 not Detecting Strikes

[Frank57]

Oh ok Don, is this the only way so far or perhaps there are others out there that maybe wrote a small program for capturing the data and even in a graphical format or am I just reaching for the stars at this early point of development of these boards coming out. Guess I'll be learning once I get a board, someday... thanks   

[miraculon]

Yes, for the rate calculation, that happens as the first strike in a new event will show a duration of zero. I didn't bother to trap for it or add a conditional statement to fix it. It doesn't affect the graphs.

Here's the latest code:

Code: [Select]

<?php
$date = date("m/d/Y");
$time = date("G:i:s");
$datetime = "$date $time";

# Retrieve all possible value names and values from Controller on strike event for testing and save to file.
# $file_test = fopen("/volume1/web/as3935_test.txt","w");
# foreach ($_GET as $key => $value)
# {
# fwrite($file_test,"$key:  $value\n");
# }
# fclose($file_test);

$strokes = $_GET['strokes'];
$disturbers = $_GET['disturbers'];
$duration = $_GET['duration'];
#$rate = $strokes;
$rate = round(($strokes/$duration*60),2);
$dist = $_GET['dist'];
$dist_min = $_GET['dist_min'];
$dist_max = $_GET['dist_max'];

if (!file_exists("/volume1/web/as3935_log.txt")) {
     $file = fopen("/volume1/web/as3935_log.txt","w");
     fwrite($file,"Date,Time,Date-Time,Event Strokes,Event Disturbers,Event Duration,Event Strike Rate,Current Strike Distance,Event Min Distance,Event Max Distance,Current Strike Energy,Event Min Energy,Event Max Energy,All Strokes,All Disturbers,Events\n");
fclose($file);
     }

Don,

Could you post the most recent updates to this script? I looked here and at BO and can't find it. I think that there were some changes since this post. Maybe some for 7.2?

I am missing some fields and your output looks more complete. Thanks.

This is the simple text-style output with the bright green backround.

You can see that I am missing data in a lot of fields now and I would like to fix that.

Well, here's an update. Amazon contacted them directly since they had a unhappy buyer. They finally emailed me back stating that emails were going to the wrong mailbox and then to top it off, stated they have had issues getting parts for the boards . Are you kidding me? They were selling them on Amazon and had 2 left, I bought one, leaving 1 left. Now they well me it will be a couple of weeks waiting for some parts even thou they had some (would have thought complete) they were selling. I don't know if I'll ever get one. Jet, PM me if you would like to sell one of them Tautic module extra ones you have. Also, were is everyone getting these programs to run these on their PC's, creating plots and charts of their data? I have seen others uploading these graphs and charts..  Thank you Frank   

Update 7/23/14: finally got an email back from them, after having Amazon contact, said they ran out of pcb's and more were coming in and that the ones listed on Amazon were also shared with the ones in Ebay, so they sold out. More were coming in next week. One question now, while I wait, I see there are 3 of these types of pcb's out there. The from Embedded, another one from Tautic and now there is another one out there, are these all the same other than the outputs and the printing, layout of the parts on them, producing the same results?

One question now, while I wait, I see there are 3 of these types of pcb's out there. The from Embedded, another one from Tautic and now there is another one out there, are these all the same other than the outputs and the printing, layout of the parts on them, producing the same results? 

Over all, I would think that they would all have pretty close to the same performance. I've asked the same question your asking now. Its been awhile since I've fiddled around with them but I'll tell you what I can remember.

From a Schematic point of view:
Comparing the data sheets from the manufacturer of the AS3935 to the Data sheets on the PCB modules, It looks like they all use pretty much the same Schematic. The few differences that I do see are related to if the PCB was setup for I2C or SPI use.

From a Layout point and Component of view:
There's not very many components to rearrange so the differences there are again minimal.
The Component values used on the PCBs are all the same as whats recommended in by the AS3935 manufacturer.

To connect them to a PC without having a micro-controller, You could use a Serial to SPI or I2C adapter. I haven't personally tried one of these though.

If you really want to see what the differences are I would recommend doing what I did and start looking at the Data sheets. As for differences in performance, I don't know if your going to find much. For anyone to really know which one works the best is going to require them to have all three just for comparison purposes. My guess on them performing close to the same is based on the fact that they all use the AS3935 chip which does have some tuning ability for the Antenna circuit. Which between the AS3935 Chip and Antenna, that's where all the detection work is being done.

Just my $0.02 worth, I don't know if this is any help to you.

Thanks for posting the scripts, Don.

I assume that the plots and data fields will be blank until the next time I get some activity from the AS3935. After twiddling with the paths and permissions, I have it working. (pending the next strikes!)

Your banner at the top of the page refers to Central time, but I am seeing UTC. Is this a server function? I didn't find anything in the scripts for time zone.

Greg H.

[dfroula]

You're welcome!

If you manually call the log_as3935.php script from a web browser, it will add an entry to the log file with date and time fields, but no valid strike data. This will make your graphs plot a bunch of empty data points. Your log file seems to have many of these empty data entries.

You might want to delete the as3935_log.txt or move it to a backup file. The script will create a new file on the first call from the controller on an AS3935 lightning event. You can also manually delete the entries with no valid lightning data with a text editor. Be sure not to leave any extra newlines in the text file, or the graphing scripts won't load the log file properly. You also need to leave the newline at the end of the log file.

I'm also updating the script to log Blitzortung server alerts in a separate log file and display a set of graphs for those events. I'm still testing those scripts.

Best,

Don

The script that writes the log file does not use the time stamp that the Controller appends when it calls the script, but calculates the time and date when it is called using the PHP "date" function. On my Linux server, a Synology NAS, the PHP "date" function returns the UTC adjusted with the local timezone. I do not think this is typical Linux behavior, though. The Synology NAS Linux variant does things differently. A more conventional Linux server will probably return UTC.

The reason I did not use the embedded timestamp from the controller is to make the formatting of the date and time easier using the PHP "date" function (first few lines of the script).

Yes, the "last strike" text data will not get updated until a strike is detected. If you have valid strike data in the log file, the graphing scripts will load the entire log file, but only display the last 300 events. If their are less than 300 events in the log, all of the entries will be displayed with wider bars on the graph.

Changing the graphing script to display much over 300 strikes seems not to work very well, likely because the Google API can't make the bars narrow enough to display all of the strikes with the graph dimensions I have specified in the scripts.

OK, thanks again. I just removed the reference to Central Time. I will just wait for some strikes, since this is the expected behavior.

You can test the graphs and text display by entering this URL in your browser. The URL will feed dummy data to the script. Substitute the domain of your web server and the path to your script, if necessary:

Code: [Select]

http://my.domain.com/log_as3935.php?strokes=25&disturbers=0&duration=180&dist=31&dist_min=1&dist_max=50&energy=28251&energy_min=5432&energy_max=50123&strokes_all=350&disturbers_all=0&events=13

Regards,

[dfroula]

BTW, the updated logging script now sets the lightning rate to zero if a strike occurs within the first 60 seconds of a new lightning "event". A new "event" is started by the Controller after some period of lightning inactivity.

The reason for this is that the rate calculation (number of event strikes / event duration) is not really valid until at least 60 seconds have elapsed. Before this was done, there were some very high strike rates being calculated that were not representative of the actual rate.

Each of the bars on the three graphs are aligned across the graphs, as new data is calculated after each strike. There will be a few zero-rate plots on the rate graph for any strikes occurring within 60 seconds of the start of a new "event".

The graphs show only individual strikes and are event-driven. They do not graph the events over a regular time interval. As the lightning rate increases, more plots will be shown.

Date,Time,Date-Time,Event Strokes,Event Disturbers,Event Duration,Event Strike Rate,Current Strike Distance,Event Min Distance,Event Max Distance,Current Strike Energy,Event Min Energy,Event Max Energy,All Strokes,All Disturbers,Events

[dfroula]

Your log file at http://www.sunrisesideweather.com/as3935_log.txt is missing the first column header line. The graphs will not display without the first header line.

Just delete as3935_log.txt and run the URL I posted with the dummy data a dozen times or so. If the log file is deleted, the script will create a new file with the correct header.

Or, add this as the first line in your existing log file:

Code: [Select]

Date,Time,Date-Time,Event Strokes,Event Disturbers,Event Duration,Event Strike Rate,Current Strike Distance,Event Min Distance,Event Max Distance,Current Strike Energy,Event Min Energy,Event Max Energy,All Strokes,All Disturbers,Events

Sorry, Don. Sometimes I confuse my web sites.
I actually have it at http://www.miraculon.net/froula/as3935_log.txt. (directory name in in your honor...)
I now have that header row, but no graphics yet.
Here is the link to the main script: http://miraculon.net/froula/as3935_stats.html

It appears you need to download the two .js packages and put them in the web/froula/ directory. The graphing scripts need those libraries to work.

Also, the first line of data in the CSV log file looks like two concatenated lines run together.

Delete the log file, then run this url from a browser. Hit refresh a few dozen times to create a new file and to load up the log file with data.

Code: [Select]

http://miraculon.net/froula//log_as3935.php?strokes=25&disturbers=0&duration=180&dist=31&dist_min=1&dist_max=50&energy=28251&energy_min=5432&energy_max=50123&strokes_all=350&disturbers_all=0&events=13

A small bug is anybody can write bum data into your log if they can access the php logging script ( as I just did)!

One question now, while I wait, I see there are 3 of these types of pcb's out there. The from Embedded, another one from Tautic and now there is another one out there, are these all the same other than the outputs and the printing, layout of the parts on them, producing the same results? 

Over all, I would think that they would all have pretty close to the same performance. I've asked the same question your asking now. Its been awhile since I've fiddled around with them but I'll tell you what I can remember.

From a Schematic point of view:
Comparing the data sheets from the manufacturer of the AS3935 to the Data sheets on the PCB modules, It looks like they all use pretty much the same Schematic. The few differences that I do see are related to if the PCB was setup for I2C or SPI use.

From a Layout point and Component of view:
There's not very many components to rearrange so the differences there are again minimal.
The Component values used on the PCBs are all the same as whats recommended in by the AS3935 manufacturer.

To connect them to a PC without having a micro-controller, You could use a Serial to SPI or I2C adapter. I haven't personally tried one of these though.

If you really want to see what the differences are I would recommend doing what I did and start looking at the Data sheets. As for differences in performance, I don't know if your going to find much. For anyone to really know which one works the best is going to require them to have all three just for comparison purposes. My guess on them performing close to the same is based on the fact that they all use the AS3935 chip which does have some tuning ability for the Antenna circuit. Which between the AS3935 Chip and Antenna, that's where all the detection work is being done.

Just my $0.02 worth, I don't know if this is any help to you.

Hi Josiah, thanks for the info and thoughts. With 3 of them out there now, maybe others have tried them and noticed any differences.

The script that writes the log file does not use the time stamp that the Controller appends when it calls the script, but calculates the time and date when it is called using the PHP "date" function. On my Linux server, a Synology NAS, the PHP "date" function returns the UTC adjusted with the local timezone. I do not think this is typical Linux behavior, though. The Synology NAS Linux variant does things differently. A more conventional Linux server will probably return UTC.

I tried all night to get it with no success. I am getting the UTC returned. How can it be adjusted for central time and date?

Dave, do you have a link to your installation?

That is where I have the files. The jquery-1.11.0.min.js wasn't showing, the 1.11.1 one was. I went to the all versions page and downloaded jQuery Core 1.11.0 - uncompressed, minified.

I am looking at the two .js files sitting in the froula directory. Still no graphs...

I just did a wget on my linux box and it finds them, but the browser claims it can't. I also moved them up a directory and changed the script URL calls to the full http://www.miraculon.net/jquery.....js src links.

[dfroula]

Greg, all three of the scripts (rate, distance, and energy) are not able to load the .js package files. They all return this error:

Code: [Select]

GET http://miraculon.net/virtual/users/e17373-19178/web/froula/jquery.csv-0.71.js 404 (Not Found) as3935_rate.html:8

Uncaught ReferenceError: $ is not defined
Perhaps you need to set executable permissions on the .js files, as they seem to be present in the web/froula/ directory.

Try to chmod 777 those two .js files.

Also, try to just specify the package file names in the three scripts without the fully-qualified path. For example, change the lines in each of the three files from:

Code: [Select]

<script src="/virtual/users/e17373-19178/web/froula//jquery-1.11.0.min.js"></script>
<script src="/virtual/users/e17373-19178/web/froula//jquery.csv-0.71.js"></script>
to

Code: [Select]

<script src="./jquery-1.11.0.min.js"></script>
<script src="./jquery.csv-0.71.js"></script>

<script src="./jquery-1.11.0.min.js"></script>

and it worked!
