M-Bus technique explanation:
M-bus is a kind of bus structure of public utility measure
instrument named Meter-Bus,or M-bus.The principle of work is data
transmission based on modulation demodulation technique on DC power
line.M-bus dedicated chip is embedded into meters and concentrator
and data translated by two wire cable.
1. Distant and reliable communication based on high speed stable
2. Discretionary cable laying ways of serial type,star type and
cross type are acceptable.
3. Non-polarity parallel line and twisted pair are used for cable
4. Anti-interference based on isolation communication
equipment,constant-current electric current loop communication
5. Auto-Login,admissible for multiple devices and multiple
communication protocol,this system is easy to be expanded.
6. Powered by M-bus cable,low quiescent power drain,this system is
suitable for meters that needs of outside power supply.
