Smart Circuit Breaker Group Commissioning via Master-Slave Wi-Fi
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current one-to-one commissioning process for smart circuit breakers in power distribution systems is time-consuming and costly, especially when a large number of devices need to be commissioned.
Innovation Solution
A method for simultaneously commissioning multiple smart circuit breakers by forming a Wi-Fi network using the ESP-NOW protocol, designating a master circuit breaker, and using a mobile energy control application to connect all circuit breakers to an IoT Hub and energy control website, eliminating the need for individual one-to-one commissioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If one-to-one commissioning procedure is used for each smart circuit breaker, then reliable device registration and configuration is achieved, but installation time and labor costs increase significantly
Solution Approach 1:
The patent merges multiple individual commissioning operations into a single group commissioning operation. The master smart circuit breaker aggregates configuration data from multiple slave breakers and transmits them simultaneously to the cloud server, converting n separate commissioning processes into one unified process that achieves the same reliable registration outcome.
Solution Approach 2:
The master smart circuit breaker acts as an intermediary between the slave breakers and the cloud server. It collects device information from multiple slave breakers locally, processes the aggregated data, and then communicates with the cloud server once, eliminating the need for each slave breaker to establish individual connections and reducing overall commissioning time.
2Ease of manufacture
If one-to-one commissioning procedure is used for each smart circuit breaker, then proper device configuration is ensured, but labor costs and operational complexity increase
Solution Approach 1:
The master smart circuit breaker performs multiple functions: it operates as a regular circuit breaker, collects device information from slave breakers, aggregates configuration data, and communicates with the cloud server. This multi-functionality allows a single device to manage the commissioning of multiple slave breakers, simplifying the overall process despite the increased number of devices being commissioned.
3Ease of operation
If individual field visits are conducted for each smart circuit breaker commissioning, then proper setup and configuration is achieved, but installation costs increase
Solution Approach 1:
The system creates a hierarchical copy structure where the master breaker receives configuration data from multiple slave breakers, processes it centrally, and then transmits the aggregated configuration to the cloud server. This copying and aggregation approach allows simultaneous commissioning of multiple devices without requiring multiple separate field visits, reducing both time and cost while maintaining proper setup quality.
