The hardware part of development mobility nonlinear video editing station is completed!!!
Station in gathering:
The solar battery:
Characteristics of the solar battery:
1. Nominal a voltage - 17V
2. The maximal current - 2.12A
3. The maximal capacity - 36W
As you could notice from previous mine blog, the system consumes in a nominal operating mode nearby 1.9A, that allows us under the certain favorable conditions of an environment, to use station as a whole with a feed from the solar battery, without the charge of a charge of the accumulator. As a result we receive true mobility, thus, with use of renewed power resources, as is one of the basic purposes of the given project.
The small deviation, concerning directly solar battery and in particular, its orientations in space, for its most effective use. As you can see from presented below figure, the sunlight can be four types:
1. Direct
2. Absorbed
3. Reflected
4. Indirect
Indirect the Solar battery will make an electricity even in cloudy weather, however the greatest efficiency is reached at absorption of a direct sunlight when the solar module is placed perpendicularly concerning solar beams. On past day time movement of the sun from the east on the west, seasonal variations take place also. On shown below figures variations of position of the sun for 1 - winter and 2 - summer periods of time are shown.
For the spring and autumn periods of time value of a corner of an inclination it is approximately equal to geographical breadth of district. For winter from this value it is taken away approximately 10-15, for summer increases approximately 10-15. If it is not obviously possible constant changes of a corner of an inclination of the solar battery, it accept equal to geographical breadth of district. By the way, it is concrete in the given project the solar battery it is established under a corner of 48 degrees. It is necessary to note, that for the automated orientation of the solar battery in space for reception of the maximal sunlight there are special the installations named geliostates.
Main advantages:
1. The finished station received by us allows to use energy of the sun, as renewed power resources that gives us mobility in moving and use of the given system to any of a part of world space.
The further work will be concentrated in following directions:
1. Studying of principles of work geliostat.
2. Connection compact, with a low level power consumption, devices of display of the graphic information of a format lcd, with an opportunity of management of data on the screen of the device.
3. Definition of the most suitable distribution kit of the operational system accessible at present for platform Efika, which will satisfy with the following made to their demands - high speed of work and presence of the necessary software for work of station.
