Send Pulsed output to Online servers

Thread starter #1
We are trying to detect the pulsed output of the lathe machine at different current input stages. We bought the wireless frequency meter and trying to test the pulsed output at the longer range of around 700 meters instead wiring we are using these wireless meters with good battery backup. Till now we were working with a local mesh network but we need to connect these sensors with online analysis platforms. But not aware of these at all, So we need some advice and the easiest way to connect the sensors with the online platform.

Will be looking forward to your replies
Hi there Derby. I don't know a lot about lathes but your post Intrigued me. Looking at it I was already wondering if you could integrate this system with something cheap and adaptable like a raspberry pi.
This got me looking through the company blurb for the device and sure enough:

"With an open communication protocol this sensor can be integrated with just about any control system or gateway. Data can be transmitted to a PC, a Raspberry Pi, to Microsoft Azure® IoT, or Arduino. Sensor parameters and wireless transmission settings can be changed on the go using the open communication protocol providing maximum configurability depending on the intended application."

Now how you go about integrating these systems would be up to you but more details of why you would like to remotely monitor a lathe (woodworking ? Industrial machinery). Is it a harsh environment or just something running on its own in a remote location.

Anyways good luck. Get back to me if you need to bounce some ideas. I'm no Einstein but I enjoy all things tech.

Hi Pommie and Daveychef

Actually its about industrial machinery, we are making a project for my spare parts industry for predictive analysis system, through a wireless mesh network. The sensor which I have mentioned are much useful and battery efficient.

According to their tutorial to use this sensor with specially designed software much nicer but we are going to design a custom function for the old lathes (which company is using much long ago) through raspberry pi.

I need to test the speed of the motor as well the vibration caused by the motor used in the lathe and send the complete analysis to server office using the internet cloud(secondary) as well as the Local long-range connection(Primary)

To strength the signal for the long range we are using the gateway receiver which strength the signal, But I am bit confused about how can I measure the speed or a pulsed output to check the status of the motor.

By any means If could help me out to make both solution work or any theoretical concept which will be much use to make this solution work will be a great help.

You want to measure the speed and vibration of a motor and continuously send it to a server? Why? Just schedule a 6 month check of the motor and order maintenance if required. OR, is there another reason that makes more sense?

The motor speed will not tell you anything useful in a predictive way.
Many machines also use variable speed drives so you don't know what it should be running at, at any particular instant.
Vibration readings are likely to be swamped by cutter vibration & vibration reading also change drastically with speed & load variations as different parts of the mechanics resonate.

Mechanical wear, lack of lubrication, swarf/dust contamination, damaged slideway covers & wipers etc. are all common problems with machine tools but need physical inspection to diagnose - that's the idea of a routine service agreement, eg. a six monthly inspection as Pommie notes.

For example, by the time a slideway demonstrates mechanical symptoms - it starts to seize up due to lack of lube or swarf ingress - you are at the point of a major stripdown to fix it.

Nothing beats the "Mk 1 Eyeball" and simple "feel" of how a machine responds for catching problem.

For data input to a central site, just use a web site with a database and have the sensor devices emulate a form entry, with the data o be added to the database.
The page / php script you post to can be hidden from the normal site pages.

That's how we manage that type of setup (though for somewhat different data).
