Introduction of LoRaWAN in an agricultural enterprise. Part 2. Fuel accounting
Hello dear readers! Since the publication of the first article, we have grown up, our favorite vendors, the developers of LoThings , have done quite a bit of hard work, and the day has come when there is something to tell and show!
By launching our first LoRaWaN, we immediately determined which tasks we want to close by means of its capabilities. One of them was the control of fuel metering at the gas station.
In general, we have 2 tanks in which fuel is stored, and a gerkon column of a domestic manufacturer.
')
We solve the problem by measuring the level of fuel in tanks, and by collecting data on the number of spilled liters through the column.
In the tanks installed FLS BI FLSensor
Now about the connection. Brains available speakers have on board RS-485. I have already met a post about LoRaWAN and RS-485 and probably will not be repeated, the author of this post wonderfully described everything before me!
Protocols are loaded into the device and all processing takes place on board. LoRaWaN network is already flying a packet with dry data, for processing on the server. Setting up the process of receiving data from the column was tedious, due to the problems with the logic of the column, with FLS everything is simple.
As a result, we receive every 10 minutes a package with data about the volume of fuel in tanks and temperatures at the moment. In the case of a perfect refueling, at its end a package arrives with the same data, but supplemented with information on the number of filled liters.
All information obtained is collected on the server and displayed in a convenient form.
That's probably all, I will gladly answer all questions in comments or hp.
In the following posts, new challenges, new victories :-)
