dc power line communication

anyone have success with power line communication over a DC bus? or know of any research papers on the subject? anyone selling such a product?

dc powerline communication

It is not difficult to "inject" data on top of dc ..
Take a look at this:

communication over dc power

I hear some time ago, a project in a german supermarket, in wich light bright was modulated with a digital protocol; So, the price at each shelf could be updated this way. ( a simple LCD modul with LED sensor ).

Note.: The rate this communication was done is high enough to be not detected by human eye.

communication over dc power line

thanks PaulHolland, that MIT thesis is exactly the kind of information i was looking for.

i am familiar with yamar's products. i think they are on the right track but they lack funding and protocal agreement between corporations to make it workable.

IanP, thx for the the tip.

if you come across any research paper or some such please post it here.

thx for the help,
Mr.Cool
 

dc powerline over dc bus

Hello,

Already there are too many protocols, therefore, we in Yamar developed solutions that do not require special protocols.
The DC-LIN allows data transfer of any UART message over the powerline in speeds up to 57.6Kbps. As a result, the LIN protocol can operate over the powerline without modifications.

simple uart over dc power

ohhh ahhh... i'll take a second look at yamar

what would i have to change to be able to use this device on a 540Vdc bus?
 

dc power line over dc bus

the device is coupled to the dc bus through a capacitor, so execpt of choosing a capacitor that will handle this DC voltage, i dont think you will need to change much.
