Smart meter (single phase) bci-cem01
Product introduction
Single-phase electronic watt-hour meter is a fully digital watt-hour meter, USES the high integration V9821S SoC chip, can measure active power, also can realize the online intelligent power display, preventing electricity-stolen, overload control, remote centralized meter reading a variety of functions, such as by LoRaWAN wireless AD hoc network to transfer the data to the corresponding gateway, with high precision, low power consumption and good stability, etc.Can be widely used in urban, rural or factory enterprises single phase ac metering occasions.
Product features
SoC MCU V9821S: enhanced 8052MCU core, power metering function, integrated simulation front end, RTC module, LCD driver, FLASH, can accurately measure and display active power;
Remote cut-off and power transmission function: according to the specific situation of power consumption, power off instruction can be issued at the main station rui to cut off the user load loop, or power transmission instruction can be issued to connect the user load loop;
The data is transmitted to the corresponding gateway through LoRaWAN wireless self-organizing network, and the data is uploaded actively. By default, the data is uploaded once every 10 minutes (the time can be set).
The communication protocol complies with DL/ t645-2007
