1results about How to "Easy to deploy at scale" patented technology

The application relates to the technical field of intelligent power distribution and electrical control, in particular to a circuit breaker address automatic allocation device and method based on voltage detection. The device comprises an internal pull-up resistor, a voltage detection point, a connection terminal and a micro control unit, a unique resistance coding resistor is arranged at a corresponding position of an external mounting base, and the two constitute a voltage division circuit. The method is characterized in that, through power-on initialization and multiple voltage sampling and filtering, characteristic quantities are calculated based on voltage division, a unique address is matched in combination with a pre-stored mapping table, and after conflict detection, the address is stored and registered. The application adopts passive resistance voltage division and voltage bit characteristic quantity design, cooperates with an anti-interference mechanism, offsets the influence of resistance tolerance and power supply fluctuation, does not need manual operation and complex modules, supports hot plug, has simple structure, low cost, fast and accurate address allocation, is suitable for multi-scale power distribution scenes, has strong stability, and is convenient for batch deployment.
