MashaAllah, thats a very good thing you want.
I'd suggest that one, you ask Allah to 1stly make it easy on you getting up for fajr and observing all of your salawat on time.
Then you should be sure to go to sleep in a dencent time so you arent too tired to get up.
Then whats a big help is to have an alarm clock InshaAllah. Until your body naturally wakes itself up. Or If you have someone wake you up thats just as good.
May Allah make it easy on you and reward your efforts Ameen
Hay do you have a computer in your room?
If so you can just download the adhaan from islamicfinder.com and leave your computer running. And when the adhaan comes on you will definatly hear it InshaAllah.
Be sure your volume on your speakers are on.
what a cool use of technology!
another thing you could try, is drinking plenty of water in the evening. you will wake up throughout the night to go to the bathroom.
good luck! (i'm a night person and can't imagine waking up at that hour).
