III. Main Structure:

DCGLW2-TQ201RType electric energy collection terminalAdopting a metal shell, it has good anti-interference performance and control circuit,485Bus. The collection terminal is equipped with measures to prevent unauthorized personnel from operating, and the cover is fixed with screws and can be sealed with lead.

4. Working principle:

Collecting terminalsRS485Interface and single-phase energy meterRS485Interface connection, the collection terminal will collect the electricity consumption data of the energy meter throughGPRSUpload to the backend server. When installing or replacing the collection terminal and energy meter, the computer's setting software must be used to set the initial parameters of the collection terminal, including the collection terminal number, the circuit number of the connected energy meter, the meter number, the meter constant, and the meter base number,MCUWrite toEEPROMIn the middle.
