| Abstract: | The M-BUS （ meter bus ） communication protocol is a remote communication bus for intelligent instruments and control equipments, In recent years it got a fairly rapid development at home and abroad. According to the M-BUS communication protocol, a new current modulation circuit is designed in this paper, This circuit is used in the remote power supply to slave of the M-BUS communication networks,Under the situation of no change the M-BUS system capacity and system hardware equipments, it is usable for terminal equipments remote power supply ability increasing from less-than 3mA to 18mA, in order to realizing terminal equipments remote power supply in short time, driving heavy load application. |
