HOW TO USE

Spread Spectrum System Construction

1) Upper Layer Communication:

Communication method indicated below can be selected between concentrator and management center.

(a) GPRS Communication Mode

(b)Telephone Line Communication Mode

(c) RS232 Communication Mode

(d) Ethernet Communication Mode

Bottom layer communication means communication between the concentrator and smart meter. It adopt wireless RF 433Mhz/470Mhz/868Mhz.

Mbus System Construction

1) Upper Layer Communication:

Communication method indicated below can be selected between concentrator and management center.

(a) GPRS Communication Mode

(b)Telephone Line Communication Mode

(c) RS232 Communication Mode

(d) Ethernet Communication Mode

2) Middle layer Communication

Middle layer communication means the communication between the concentrator and collector. This communication is by wireless RF way, no need of communication line. The wireless communication distance between the concentrator and collector can be about 3km at open environment.

Each piece of concentrator can manage 255 pieces of collector maximally.

3) Bottom Layer Communication
Bottom layer communication means communication between the collector and water meter.

Wireless network signal has the positive of wide signal propagation, wide coverage area ability, fast construction. One piece of collector can connect with 128 pieces of meter maximally.
