Abstract: Uređaj za smanjenje utroška električne energije prilikom korištenja dizala funkcionira na način da pomična podnica u kabini, koja se spušta kada putnici stanu na nju ili se podiže kada putnici izlaze iz dizala, služi kao vaga koja u svakom trenutku može utvrditi točnu težinu putnika u kabini dizala.<BR/> Podizanje i spuštanje podnice u kabini dizala može poslužiti i za pogonjenje mehanizma za pomicanje dijelova protu-utega iz prostora ili polica u oknu dizala, a koji se nalaze u prizemlju i na svakom katu u osnovni protu-uteg ili obratno.<BR/> Na temelju vaganjem utvrđene težine putnika u kabini dizala vrši se izračun i raspodjela dijelova protu-utega iz prostora ili polica u oknu dizala u osnovni protu-uteg ili obratno.<BR/> Izračunavanje i utvrđivanje optimalnog odnosa težine kabine s putnicima s težinom protu-utega vrši se korištenjem odgovarajućeg elektronskog sustava na bazi heurističkog algoritma koji bi prilikom izračunavanja optimalnog odnosa težine kabine i težine protu-utega koristio podatke o težini putnika utvrđene vaganjem pomoću podnice kabine, kao i podataka o frekvenciji putnika u određenom vremenskom razdoblju, kao i podatke o već odloženim dijelovima protu-utega.<BR/> Nakon izračunavanja i raspoređivanja dijelova protu-utega na način da se postigne da protu-uteg bude teži od kabine s putnicima kada se dizalo podiže, ili da težina protu-utega bude manja od težine kabine s putnicima kada se dizalo spušta, za korištenje dizala bit će potrebna znatno manja količina električne energije, jer će se električna energija za pokretanje elektromotora koristiti samo u slučaju kada se neće moći uspostavit gore opisani odnos težine kabine i protu-utega.A device for saving electric energy when using the elevator functions in the way that flexible footing in the booth, which drops down when passengers step on it or lifts up when passengers exit from the elevator, serves as a balance that can identify exact weight of passengers in the elevator booth at any moment. Lifting up and dropping down of the footing can also be used to drive a mechanism for moving counterweight parts from the space or shelves in the elevator shaft, and which are located on the ground-floor and on every floor into the basic counterweight and vice versa. Based on the weight of passengers in the elevator booth identified by weighing, the counterweight parts are being calculated and distributed from the space or shelves in the elevator shaft into the basic counterweight and vice versa. Optimum ratio between the booth weight with passengers and the counterweight is calculated and determined by using an appropriate electronic system; when calculating optimum ratio between the booth weight and the counterweight, this electronic system would use data on the weight of passengers identified by weighing with the aid of the booth footing, as well as data on the frequency of passengers in a certain time period, and data on counterweight parts already disposed. After counterweight parts are calculated and distributed in the way to achieve that the counterweight outweighs the booth with passengers when the elevator is lifting up, or that the weight of the counterweight is lower than the booth weight with passengers when the elevator is dropping down, the elevator will require much less electric energy, because electric energy for activation of an electromotor will be used only in case when it will not be possible to establish the ratio between the booth weight and the counterweight as described above.
