Abstract

The invention discloses a flushing control method and system of a toilet bowl and a urinal. The flushing control method comprises the following steps: 1) continuously detecting a human body distance signal through a millimeter wave sensing module; 2) judging whether a human body enters an effective sensing area according to the human body distance signal, if so, judging that a human body target enters the effective sensing area, and entering a step 3), and if not, returning to the step 1); 3) judging whether the time duration of continuously detecting the human body distance signal in the effective sensing area is greater than or equal to T1, if so, judging that the human body target is using the urinal, and entering a step 4), otherwise, judging the target as an invalid target, and ending; and 4) judging whether the time duration of continuously detecting the human body distance signal in the effective sensing area is greater than or equal to T2, if so, judging that the human body target leaves, and starting flushing, and if not, judging that the human body target does not leave, and repeating the step. According to the invention, the interference target can be effectively identified, and the error impact phenomenon caused by long-time static dynamic detection of the human body target can be overcome.

Description

technical field [0001] The invention relates to the field of bathrooms, in particular to a toilet flushing control method, system and urinal. Background technique [0002] Existing millimeter-wave or microwave-based sensing probes mainly use the Doppler principle to perform dynamic sensing detection of human body movements. Dynamic induction detection uses the Doppler phenomenon to detect the human body approaching or moving away, gestures, and body shaking when urinating, and then automatically delays for a certain period of time after the main control board program algorithm detects the human body movement ( For example, 3s) is used as a detection method for the human body to confirm the time before the flushing device, so as to determine whether someone is using the flushing device, and then control the switch of the flushing valve to flush after no human body movement is detected. [0003] This microwave dynamic sensing method based on the Doppler principle is too sensi...
