- Software for management system


Let's first understand in theory, what are the technologies/protocols we use to send and receive information in the end? We use two data transmission protocols: ZigBee and LoRa: ZigBee and LoRa.


Zigbee is a specification for upper layer network protocols, the application support sublayer (APS) and the NWK network layer, which use lower layer services, the MAC environment access control layer and the PHY physical layer, as regulated by the IEEE 802.15.4 standard. Zigbee and IEEE 802.15.4 describe wireless personal area networks (WPAN). The Zigbee specification is focused on applications that require guaranteed secure data transmission at relatively low speeds and the possibility of long-term operation of network devices on autonomous power sources (batteries).


LoRa uses license-free sub-gigahertz radio frequency bands such as EU433 (433.05-434.79 MHz) and EU863-870 (863-870 / 873 MHz) in Europe; AU915-928 / AS923-1 (915-928 MHz) in Australia; US902-928 (902-928 MHz) in North America; IN865-867 (865-867 MHz) in India; and AU915-928 / AS923-1 and EU433 Southeast Asia. LoRa provides long-distance transmission with low power consumption. The technology covers the physical layer, while other technologies and protocols, such as LoRaWAN (Long Range Wide Area Network), cover the upper layers. It can reach data rates from 0.3 kbit/sec to 27 kbit/sec, depending on the expansion factor.


As you can understand from the figures above, the solutions do not need a lot of equipment. It is enough to have 3 basic elements:
1) DTU (data transport unit), i.e. gateway or as we say in Russian data transfer bridge.
2) RTU (remote terminal unit) remote terminal.
3) A computer with an Internet connection.

The DTU operates on a 24 or 12 volt system and can be connected to either a power supply or a battery. A SIM card is inserted inside the DTU to create a network between the DTU and the cloud storage/server. The RTU is already inside the pole itself, with a 12 or 24 volt battery, our cylindrical solar panels and lights connected to it. RTU is also a charging controller, it collects information about how much electricity comes into the battery from the solar panel, the current charge of the battery, the consumption of electricity. All collected information each RTU sends to the DTU, and the DTU in turn sends all data to the server, where the end user after sending the request receives the necessary information on the column of interest.

Program interface

We have read all the theory, now we can get acquainted with the program interface and see how it all works visually.

As we wrote above, the RTU is also a solar panel battery charging controller and turns the lights on and off at certain times. In this software we can edit the parameters of our device, and in the specific example of the pole. By specifying these parameters we let the controller know what voltage can be supplied to the batteries and when the lamp should turn on. We have available such parameters as: the name of the lamp, the voltages of the solar panels to turn on the light (transition to night mode), type of battery, full battery charge, floating voltage (voltage at which the battery will maintain its capacity for self-charge), battery discharge, temperature.

After setting the necessary parameters, we bind the given type of battery to the required RTU, then the pole charging and its electrical power supply will work correctly.

That's it, in a nutshell we showed you our whole system, from theory to practice. Thank you for your attention! If you have any questions, we are of course open to dialogue.
