Solution Overview
Problem
Existing methods for monitoring power consumption in household devices require installation of a current sensing device in the distribution board, which is dangerous and difficult for ordinary people to perform, and typically necessitate a wired connection, limiting remote monitoring and energy savings opportunities.
Innovation Solution
A wireless power sensing device with a CT sensor is installed in the distribution board to sense current, calculate power usage, and transmit data to a cloud device for analysis, allowing for remote monitoring and energy management without the need for direct electrical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate power usage checking device is installed in the distribution board with electrical connections, then power consumption monitoring capability is achieved, but installation safety and ease of operation deteriorate due to dangerous electrical work requirements
Solution Approach 1:
The patent replaces wired electrical connections with wireless communication technology. The power usage checking device communicates with the mobile terminal via wireless signals (WiFi, Bluetooth, etc.), eliminating the need for dangerous electrical wiring work while maintaining accurate power consumption monitoring capabilities.
Solution Approach 2:
The patent introduces a mobile terminal as an intermediary device between the power usage checking device and the user. The mobile terminal receives power consumption data wirelessly from the checking device and presents it to the user through an application interface, serving as a safe intermediary that eliminates direct electrical connection requirements.
2Device complexity
If power usage checking is limited to when the user is at home, then system complexity is reduced, but energy saving opportunities deteriorate due to inability to monitor and control remote devices
Solution Approach 1:
The patent makes the power monitoring system universally accessible through the user's mobile terminal, which can be accessed from anywhere. The mobile terminal application provides a unified interface that works both when the user is at home and when away, enabling remote monitoring and control functions without requiring separate systems.
Solution Approach 2:
The patent implements real-time feedback by continuously transmitting power consumption data from the checking device to the mobile terminal. This allows users to receive immediate notifications about abnormal power usage, device status changes, and to remotely control connected devices regardless of their location, enabling timely energy-saving actions.
