The dual-mode data acquisition system is a new type of data acquisition system independently developed by Friendcom. The system adopts dual-mode communication technology of micro-power wireless and power line narrow-band carrier to realize self-organization and self-maintenance functions of data acquisition communication network. Through the combined use of the two communication modes, it is possible to avoid (two communication methods) respective communication blind spots, provide more and more reliable routing options, thereby improving the stability of network communication. Utilize the characteristics of the two communication methods to achieve speed priority and meter reading experience priority, and provide a high-speed and stable communication method for electricity consumption information collection.
The electric energy meter supplies power to the FC-626NB3 module through VCC (12V).
The data is as follows
Idle mode: VCC power (12V) input <17mA;
Receiving mode, VCC power (12V) input <20mA;
Transmitting mode: VCC power (12V) input <50mA;
FC-626NB3 works in 32 channel groups, each channel group has 2 frequency points
