Abstract

U radu je prikazan razvoj i konstruiranje uređaja s vremenski ovisno rukovanim vratima, to jest automatskih vrata za farmu peradi koja se otvaraju i zavaraju prema unaprijed definiranom rasporedu, ovisno o danu u godini i vremenu u danu.
Razvoj koncepta zahtjeva dizajn mehanizma konstrukcije i odabir potrebnih elektroničkih komponenta Mikrokontroler prima podatke sa svih senzora u uređaju te prema dobivenim informacijama slijedi zadani algoritam. Točan datum i vrijeme dobiva uz pomoć Real Time Clock-a (RTC-a), informaciju o položaju vrata od infracrvenog senzora udaljenosti, a jakost struje kroz motor javlja digitalni ampermetar. Kao sigurnosna mjera za zaštitu životinja postavljen je ultrazvučni senzor. Uređaj također sadrži GSM modul koji u slučaju problema prilikom pomicanja vrata šalje SMS obavijest na zadani broj mobitela.
Kako bi bio konkurentan na tržištu, cijena uređaja mora biti što niža, a njegove mogućnosti što bolje.

Abstract (english)

This thesis presents the development and construction of a device with a time-dependent door, i.e. an automatic door for a poultry farm that opens and closes according to a predefined schedule, depending on the day of the year and the time of day.
The development of the concept requires the design of construction mechanism and the selection of the required electronic components. Microcontroller receives data from all sensors in the device and according to the received information follows the default algorithm. The exact date and time is obtained with the help of Real Time Clock (RTC), information on the position of the door from the IR distance sensor and the current through the motor is reported by a digital ammeter. As a safety measure for animals, an ultrasonic sensor was installed. The device also contains a GSM module which will send an SMS notification to the default mobile phone number in case of any issues.
To be competitive on the market, the price of the device must be low and its capabilities as good as possible.
