Electric carrier meter and carrier communication;

The system takes P87LPC76X OTP single chip computer as the core processor,helps to realize carrier wave communication through power line and net mark and cyclic redundancy check(CRC),so the system communication reliability is improved.

In this paper characteristics of carrier wave communication and automatic meter reading technology are deeply studied in China.

Based on the technology of the low voltage electric power carrier wave communication,the system of collecting search meter can search collecting energy meter on the far way,monitor the energy,and calculate the circuitry wastage,this can reduce issues of multifarious loads in collecting energy revenue.

The trial shows that the device can meet the needs of hierarchical and real-time control in distribution automation by using multiple logic communication networks based on virtual carrier sense mechanism.

It shows that the device can meet the needs of hierachical and real-time control in its application by using multiple logic communication networks based on virtual carrier sense mechanism, enhanced adaptive analog front end of receiver, adaptive frequency bands and coupling means etc.
