MPU

„MPU“ je android aplikacija koja izvršava mehanični proračun zaštitnih užadi, ili faznih provodnika, nadzemnih vodova, kao i brojne proračune vezane za projektovanje dalekovoda naponskog nivoa ≤110 kV, sa rasponima ≤500m i uglom nagiba u rasponu ≤30°.

Podržava sve android verzije počev od „jelly_bean“ (API nivo: 16), odnosno 99% svih android uređaja koji su danas u upotrebi.

Postupak mehaničkog proračuna užadi je dobro poznat i postoje brojni softverski alati koji ga izvršavaju. Namena ovog programa – android aplikacije, je da omogući inženjerima neposredno izvođenje mehaničkog proračuna dok su još na terenu, uporedo sa njihovim operativnim aktivnostima na snimanju trase dalekovoda. Dakle, eliminiše se potreba za povratkom u kancelariju radi pristupa desktop računaru, CAD programu i specijalizovanim programskim dodacima za mehaničke proračune i crtanje lančanica. Na licu mesta se proverava idejno rešenje i kontroliše ispunjenost tehničkih propisa. Dovolјan je samo pametan telefon ili tablet, a to je praktično uvek pri ruci.

Na taj način se smanjuje vreme potrebno za izvršavanje radnih zadataka koji se odnose na proveru sigurnosnih visina provodnika nadzemnih vodova, kontrolu naprezanja i ugiba pri ukrštanju dalekovoda, i sl. Tokom snimanja predmetne situacije na terenu (merenja rastojanja, kota, stacionaža i sl.), korisnik ove aplikacije može paralelno da u nju unosi parametre mehaničkog proračuna, i da na osnovu rezultata, na licu mesta, odredi da li su npr. zadovoljene sigurnosne visine iznad nekog objekta, ili pri ukrštanju dva dalekovoda, ili da li će se umetanjem novog stuba u postojeću trasu voda rešiti problem prelaska dalekovoda preko nekog stambenog objekta, i sl. Time korisnik aplikacije direktno na terenu proverava da li konkretno rešenje zadovolјava propise i unapred zadate uslove, i u zavisnosti od toga usvaja rešenje ili nastavlјa sa snimanjem terena tražeći novo.

Aplikacija je na srpskom jeziku, bez reklamnih sadržaja. Sastoji iz nekoliko nezavisnih celina – modula, a svaki od njih izvršava konkretan proračun:

„Reši jednačinu stanja“

„Tabele ugiba“

„Ukrštanje dva DV“

„Stvarno naprezanje“

„Provera sigurnosnih visina“

„Očitaj uzdužni profil trase“

„Tipovi užadi“

„Temperatura provodnika“

"MPU" is an android application that executes mechanical calculation of protective ropes, or phase conductors, overhead lines, as well as numerous calculations related to the design of power line transmission lines ≤110 kV, with ranges of ≤500m and angle of inclination in the range of ≤30 °.

It supports all Android versions starting from "jelly_bean" (API level: 16), or 99% of all Android devices that are in use today.

The mechanical calculation of the rope is well known and there are numerous software tools that perform it. The purpose of this program - android application, is to enable engineers to directly execute the mechanical budget while they are still on the ground, along with their operational activities on taking the route of the transmission line. Therefore, the need to return to the office is eliminated to access the desktop computer, the CAD program and specialized software add-ons for mechanical calculations and drawing of sprockets. The concept solution is checked on the spot and it controls the compliance of technical regulations. Just a smart phone or tablet is enough, which is practically always at hand.

This reduces the time required to carry out work tasks related to checking the safety altitudes of overhead conductors, controlling the stresses and defects in crossing the transmission line, and the like. During the recording of the subject situation in the field (measuring distance, angle, station, etc.), the user of this application can simultaneously enter the parameters of the mechanical calculation in it, and, based on the results, on the spot, determine whether, for example, satisfied safety height above an object, or when crossing two transmission lines, or whether the insertion of a new pillar in the existing water route will solve the problem of crossing the transmission line over a residential building, and the like. By doing this, the user of the application directly in the field checks whether a particular solution meets the rules and conditions in advance, and, depending on that, adopts the solution or continues shooting the terrain for a new one.

The application is in Serbian, without any advertising content. It consists of several independent units - modules, each of them executing a concrete budget:

"Solve the equation of the state"

"Tables of blur"

"Crossing two DVs"

"Real Stress"

"Safety height check"

"Read the longitudinal profile of the route"

"Types of ropes"

"Conductor Temperature"
