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.
Technical characteristics:
1.Distant and reliable communication based on high speed stable communication rate.
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 laying.
4.Anti-interference based on isolation communication equipment,constant-current electric current loop communication system.
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.
