Abstract

Käesolevas töös arvutasin drooni süsteemi tööks vajaliku kaabli tüübi ja parameetri. Ankurdatud drooni süsteemi kõige tähtsamaks osaks on kaabel, kuna varustabdrooni elektriga, hoidmaks seda töös. Seega peab kaabel olema tugev ja vastupidav ümbritsevatele tingimustele, näiteks UV-valguse, soojuse mõjule, mehaanilise kulumisele ja olema veekindel. Arvestades drooni piiratud tõstevõimet, peab kaabel olema kerge. Seega tegin valiku GORE kaabli kasuks, sest see pakub parimaid mehaanilisi ja elektrilisi omadusi antud tingimustes. Kaabijuhtme ristlõike pindalaks on 1,5mm2 ja kogupikkuseks 100 m. Üksikasjalikud spetsifikatsioonid on toodud välja tabelis ning kaabli tootjate veebilehel. Kaabli kaal on 19 kg/km, seega 100-meetrise kaabli korral on kogukaaluks 1.9 kg. Valitud kaabel on võimeline ohutult läbi laskma kuni 10 A juures 230 V, mis on tunduvalt rohkem mida drooni vajab enda tarbeks. Tänu GORE kaablis olevale valguskiule saab lisaks elektrivarustamisele kasutada kaablit ka andmete edastadastuseks drooni ja maapealse tugisüsteemi vahel, kui lisada drooni külge raadioantenne, infrapunaandureid või kaameraid. Antud töö käigus selgus, et olemasolevate kaablite valik on piiratud ja vajaminevat kaablit on vaja kas ise valmistada või osta eritellimusel. Droonidele sobivaid kaableid toodab ainult paar ettevõttet. Seoses sellega tuleks uurida kas on turgu sellise ettevõtte loomiseks, mis tegeleb kaablite tootmisega.

Abstract [en]

In this work, I calculated the cables type and parameters required for the operation of the tethered drone system. The most important part of the tethered drone system is the cable, as it supplies the electricity needed to keep the system running. Thus, the cable must be strong and resistant to enviromental conditions such as exposure to UV light, heat, mechanical wear, and it has to be waterproof. Given the limited lift capacity of the drone, the cable must be light. Therefore a choice was made for the GORE cable because it offers the best mechanical and electrical properties under the given conditions. The cross-sectional area of the cable is calculated to be 1.5 mm2 and the total length is 100 m. Detailed specifications are provided in the table and on the cable manufacturers website. The weight of the cable is 19kg/km, so for a 100-meter cable the total weight is 1.9kg. The selected cable is able to safely handle up to 10 A at 230 V, which is much more than the need for the drone. Thanks to the optic fiber in the GORE cable, in addition supplies power needed for the drone, the cable can also be used to transmit data between the drone and the ground support system if radio antennas, infrared sensors or cameras are attached to the drone. In the course of this work, it was found that the choice of existing cables is limited and that it is necessary to make the cable yourself or buy it as a special order. Only a few companies produce cables suitable for drones. In this context, it should be investigated whether there is a market for the creation of a company dealing with cable production.
