Problem
Existing smart electrical appliance technologies face challenges in accurately detecting a user's arrival at a target area, which affects the timely and efficient control of connected devices, such as turning on an air conditioner or water heater.
Innovation Solution
A method and apparatus that search for a target wireless access device in a target area at a preset frequency, establish a connection with it, and determine the user's arrival by various means like screen lighting, Bluetooth responses, or proximity, allowing for timely and accurate detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If continuous scanning for wireless access device is performed to ensure accurate detection of user arrival, then detection accuracy is improved, but battery consumption increases
Solution Approach 1:
The patent implements periodic scanning at preset frequencies instead of continuous scanning. The terminal scans for wireless access devices at specific intervals (e.g., every few seconds or minutes), which maintains detection accuracy while significantly reducing battery consumption compared to continuous scanning.
Solution Approach 2:
The patent performs preliminary actions by detecting user movement or location changes before initiating the scanning process. When the terminal detects that the user is moving or has changed location, it triggers the scanning operation, ensuring timely detection without requiring constant scanning.
2Loss of time
If scanning frequency is increased to detect user arrival in time, then response time is improved, but power consumption increases
Solution Approach 1:
The patent uses periodic scanning at optimized frequencies to balance response time and power consumption. By scanning at preset intervals rather than continuously, the system maintains timely detection of user arrival while avoiding excessive power consumption associated with high-frequency continuous scanning.
Solution Approach 2:
The patent dynamically adjusts scanning behavior based on detected conditions. When user movement or location change is detected, the scanning frequency is increased to ensure timely detection. When no movement is detected, scanning frequency is reduced or paused, optimizing the balance between response time and power consumption.

AI summary
The present invention relates to a detecting method and apparatus, a computer program and a recording medium, which can accurately detect a user's arrival at a target area. The method comprises: activates searching for a target wireless access device at a preset frequency; after the target wireless access device is searched out, establishing a connection therewith; after the connection with the target wireless access device is established, determining that the user arrives at the target area. According to the technical solution of this invention, by continuously searching for a target wireless access device and by determining that a user arrives at a target area after establishing a connection with the target wireless access device searched out, the target wireless access device can be searched out and a communication connection therewith can be established in time. Once the connection is established successfully, it is determined that the user arrives at the target area, so that the user's arrival at the target area can be detected more accurately.
