Solution Overview

Problem

Smart sockets face safety hazards and reduced service life due to excessive power usage from electric equipment, as existing technologies lack effective monitoring and control mechanisms to prevent such conditions.

Innovation Solution

An information prompting method and device that acquires temperature in smart sockets, compares it with a preset threshold, generates alarming information if power exceeds acceptable limits, and pushes alerts to mobile terminals, optionally cutting off power to prevent damage.

VSEngineering Contradiction Analysis

1Productivity

If electric equipment with excessive power is plugged into a smart socket, then the equipment can be powered to work normally, but safety hazards arise and service life of the smart socket is shortened

Engineering Contradiction:
Improvepower supply capabilityVSAvoidsafety and service life
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system performs preliminary temperature monitoring and power detection before damage occurs. The temperature detection module continuously monitors the smart socket's temperature, and the control module compares detected temperature with preset thresholds to identify excessive power conditions before they cause safety hazards or shorten service life.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system establishes a feedback loop where the temperature detection module continuously monitors temperature, the control module processes this information and compares it with thresholds, and the alarm module provides feedback to users through alerts. This closed-loop feedback mechanism enables real-time detection and response to excessive power conditions.

AI summary

The present disclosure relates to overtemperature protection in a smart socket. The method includes: temperature in a smart socket is acquired (201); the temperature in the smart socket is compared with a preset temperature threshold value, and it is determined whether power of electric equipment connected with the smart socket is higher than an upper limit of an acceptable power range of the smart socket according to a comparison result (202); when the power of the electric equipment is determined to be higher than the upper limit of the acceptable power range of the smart socket, alarming information indicating that the power of the electric equipment is excessively high is generated (203); and the alarming information is pushed to a mobile terminal bound with the smart socket (204).
