Detecting Well Liquid loading with, Azure IoT, ML, and Pi

Overview

05.19.2007 003Legacy IIoT devices can be modernized utilizing edge of network devices to send data to the Azure IoT hub and Machine Learning. This can create cost and efficiency improvements and reduced downtime.

 

The issue(s)

I will try to quickly explain the issue of liquid loading and slow legacy communications. Keep in mind there are many other issues that can be alleviated with this solution and there is no way I could mention them all. Oil & Gas Wells can “Load Up” with liquid reducing production and possibly incurring costly intermediation to relieve the issue. In the Machine Learning Video at the bottom of this post I go into great detail about this issue.

Hackster MQTT Presentation and Demonstration

The August 2016 DFW Hackster MQTT meeting was a blast. Here is a link to the online presentation. https://sway.com/DpyBV3JjNYoTFrsx

If you check back on this post I will update it with related videos. I promised some people at the event to do an Arduino MQTT demo and also finish up my video on the MQTT garage door opener.

 

If you want to get started with MQTT in your own time here are some resources:

What is MQTT

 

TI LaunchPad MQTT demo.

 

Software to Download:

Download HiveMQ it is free but they will make you fill out contact information for the download link. There is lots of great info and white papers on MQTT here so stay awhile and do some reading!

You will need a MQTT test client, I suggest MQTT.FX

Here are source code samples for NodeMCU, WeMos, and TILaunchpad.

Launch Node-Red On Startup With a Batch File

I want Node-Red to start up (and other command line programs) when Windows 10 starts. Batch files are a simple way to achieve this.

One feature, bad or good, is the batch file will open a command prompt window that essentially acts like a live log viewer for node-red. This is fine for my application because I have a PC dedicated running 24-7 for a camera video server, MQTT server, and now Node-Red. I like being able to see what Node-Red is doing, if you want Node-Red to run in the background as a service you will want to use a different method.

Custom Cortana MQTT Commands

 

image Cortana can easily be extended to aid you with your DIY home automaton projects. In this example Cortana sends MQTT commands to open and close a garage door as well as ring the doorbell with custom jingles. By the way, you don’t have to use MQTT, you can also do a whole lot of other things as well from opening a file, opening a program, or launching your favorite websites.

As of the writing of this entry I am frantically trying to finish documenting the MQTT Doorbell and Garage Door Opener devices in separate posts. Hopefully I can get those whipped out in a few days.

TI LaunchPad MQTT I/O Demo

This demo connects two TI LaunchPad devices together using MQTT. I have every intention to add other devices to the mix like Arduino, Netduino, RaspBerry Pi, and BeagleBone in the future.

HC-21 Simple Wifi Serial for Arduino Tutorial

The Simple Wi-Fi HC-21 module is a meager $10-$15 bucks on ebay right now. It is a simple Wi-Fi serial port server or virtual serial port. This means it is self contained and will handleimage all the overhead of negotiating a Wi-Fi connection and communication leaving more room for your application in the Arduino.
