power line carrier transmission
1.Based on the AN1000,a power line carrier modem of the Adaptive Networks,serial communication protocol is developed,over Win32 operation system with Win32 communication API,to establish a robust LAN in the low voltage electric network and realize data transmission among computers.
2.Parasitic transmission in stead of wired transmission is introduced to transimit information between master computer and extensions in computer management sytem,namely,to use carrier module LM1893 to concoct signals,and to borrow the power line in the computer room to transmit data and instrustions. Hardware design and software design in detail are also given.
