The design unit is used to further analyze the characteristics of customers based on their status, determine the unique characteristics of customers in their respective customer categories, and adjust the initial simulated flowing music based on these unique characteristics to obtain the final simulated flowing music. The playback unit is used to determine the time when a customer goes to the toilet based on the customer's characteristics, and to play the final simulated running water music before the preset time period.

6. A simulation-assisted system for a restroom according to claim 5, characterized in that, The defined unit includes: The state matching unit is used to determine the customer's gender based on the customer's height and contour features, select a state analysis rule based on the customer's gender, analyze the customer's movement speed and posture features according to the state analysis rule, and determine the first state corresponding to the movement speed feature and the second state corresponding to the posture feature. The state determination unit is used to determine whether the first state and the second state are consistent. If they are, the first state is determined to be the customer's final state. The state determination unit is also used to determine that when the first state and the second state are inconsistent, to obtain the attitude features in the first interval determined by the state analysis rules, to determine the position of the attitude features in the first interval, and to determine whether the position of the first interval is greater than the first preset interval position range. If so, determine the first state as the customer's final state; Otherwise, the movement speed feature is obtained in the first interval determined by the state analysis rules, and the position of the movement speed feature in the second interval is determined. It is then determined whether the position of the second interval is greater than the second preset interval position range. If so, the second state is determined to be the customer's final state; otherwise, the first state is determined to be the customer's final state.

7. A simulation-assisted system for a restroom according to claim 5, characterized in that, Design units include: The comparison unit is used to obtain the standard features corresponding to the customer's current state, compare the customer's features with the standard features, and determine whether the feature difference is within the preset feature difference range. If so, the initial simulated flowing water music will be used as the final simulated flowing water music; Otherwise, extract the features that are not within the preset feature difference range from the customer's characteristics as unique features; The deviation value determination unit is used to perform feature analysis on unique features and determine the deviation value of the unique features; The adjustment trend determination unit is used to determine whether the deviation value is greater than 0. If it is, it determines that the adjustment of the initial simulation flowing music is to be accelerated as a whole; otherwise, it determines that the adjustment of the initial simulation flowing music is to be slow as a whole. The adjustment range determination unit is used to determine the adjustment range of the initial simulated flowing music based on the deviation value, and to adjust the initial simulated flowing music to be faster or slower overall according to the adjustment range.
