AI Technical Summary

Technical Problem

Existing infrared emitting and receiving diodes in cleaning equipment suffer from signal inconsistencies and are susceptible to contamination, resulting in low accuracy in particulate matter concentration detection. Furthermore, the vacuum cleaner motor emits significant radiation interference during operation, affecting signal stability.

Method used

By controlling the signal transmission module to output a signal at the target transmission power and preset frequency, the continuous detection signal voltage value of the signal receiving module is obtained, the voltage fluctuation parameters are calculated, the standard voltage value is updated to eliminate signal differences, and the transmission power is automatically adjusted to maintain stability, thereby achieving accurate detection of particulate matter concentration.

Benefits of technology

It improves the accuracy and stability of particulate matter concentration detection, and can automatically update the standard voltage value during use, reducing system instability and ensuring that cleaning equipment can accurately obtain particulate matter concentration.

Abstract

The application relates to a method and device for detecting the concentration of particles in a cleaning device, and a cleaning device. The method comprises outputting a transmission signal at a target transmission power and a preset frequency by a control signal transmission module; obtaining a first target voltage value of m continuous detection signals output by a signal receiving module, and calculating a voltage fluctuation parameter corresponding to the first target voltage value of the m detection signals; when the voltage fluctuation parameter represents that the first target voltage value is stable in a set time period, updating a standard voltage value, which is a voltage value in a particle-free state; and determining the concentration of particles according to the standard voltage value and the first target voltage value. Since the data of different particle types in a certain period are analyzed and processed in the embodiment, the concentration of different particles can be accurately and stably obtained.
