The Design of Remote Automatic Meter-Reading System's Communicational Reliability

RS-485 communication mode is widely used in remote automatic meter-reading system. In practical application, no reliance can be placed on the transmitting-receiving communication data. What's more, under the mode of multi-machine communication, the fault of one panel point may lead to the breakdown of the whole system of the communication structure. Thus there may be difficulties in identifying the faults. Therefore, effective measures should be taken in the software and hardware design for RS-485 bus interface in meter-reading system. In this way, the reliability and stability of the network system can be improved.
