浇水警告装置

Watering warning device

US-7349764-B2

用于确定植物浇水间隔的警告装置。

专利摘要

描述了一种用于确定至少一个待监测植物的浇水间隔的浇水警告装置(1),具有至少一个水分含量传感器(2)、定时器(6)和评估单元(3)。评估单元(3)设计用于根据随时间(t)变化的特征浇水曲线(S)确定至少一个监测植物的下一次必要浇水操作的时间(tG),浇水曲线(S)可以在至少一个学习阶段中以自学习方式从在浇水时间测量的低水分值(FGN)、在浇水时间之后的浇水操作完成后测量的高水分值(FGH)以及用定时器(6)确定或外推的直到达到低水分值(FGN)的时间(tN)确定。

Original abstractA watering warning device ( 1 ) for determining watering intervals for at least one plant to be monitored, having at least one moisture content sensor ( 2 ), a timer ( 6 ) and an evaluation unit ( 3 ) is described. The evaluation unit ( 3 ) is designed for determining the time (t G ) of the next necessary watering operation for the at least one monitored plant in dependence on a characteristic watering curve (S) over time (t), the watering curve (S) being determinable in a self-learning manner in at least one learning phase from a low moisture value (FG N ), measured at a watering time, the high moisture value (FG H ), measured after completion of the watering operation following the watering time, and the time (t N ) until the low moisture value (FG N ) is reached, determined with the timer ( 6 ) or extrapolated.
