Description

一种营养液的控制方法及控制装置
本申请要求于2017年01月18日提交中国专利局、申请号为201710038327.1、发明名称为“一种营养液的控制方法及控制装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及农业无土栽培技术领域，尤其涉及一种营养液的控制方法及控制装置。
背景技术
无土栽培以人工制造的作物根系环境取代土壤环境，有效解决土壤栽培中存在的水分、空气、养分的供应矛盾。目前，无土栽培已广泛应用于培养瓜果、蔬菜等农作物，以减少土壤中的各种草虫病害，避免了水分的大量渗透和流失，保证了农作物的健康生长并提高了肥料的利用率。
无土栽培有多种方式，具体可以分为水培方式、雾培方式、基质栽培方式三种。无土栽培用营养液代替土壤，植物从营养液中吸收养分。现有技术中，营养液的供给方式主要有两种：一种是按照固定的时间间隔向培养的作物提供一定量的营养液；另一种是根据累计光照达到一定值时向培养的作物提供一定量的营养液。
通过上述描述的两种方式可知，对于营养液的供给量是按照经验确定的。在提供营养液时，由于不同的作物在不同的生长阶段对营养的需求量都不一样，可能会造成供液量不足，也可能会造成供液量太多，浪费肥料并造成其他隐患。例如，在蔬菜快要成熟时，需要的营养液量会明显减少，同时过多的营养液造成不易采摘且浪费资源。目前的培养方式没有根据植物生长模型或者植物成熟度进行营养液供给量的控制手段，营养液利用率低，营养液浪费大。

具体实施方式
本发明实施例提供了一种营养液的控制方法，用于控制植物在生长的不同阶段对应不同的营养液供给量，实现营养液的科学配置，减少营养液的浪费，提高资源利用率。
为了使本技术领域的人员更好地理解本申请方案，下面将结合本发明实施例中的附图，对本发明实施例进行描述。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”或“具有”及其任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、***、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
现有的技术方案中，对于营养液的供给量是按照经验确定的。在提供营养 液时，由于不同的栽培植物在不同的生长阶段对营养的需求量都不一样，按照统一的标准进行供给，可能会造成供液量不足，也可能会造成供液量太多，造成营养液的浪费，增加了生产成本，并且可能会导致栽培植物摘采困难等其他隐患。
为便于理解，下面对本发明实施例的具体流程进行描述，请参阅图1，本发明实施例中营养液的控制方法一个实施例包括：
101、获取栽培植物的种类信息。
获取种植设备中栽培植物的种类信息，不同的植物种类对应的生长模型不同，生长模型反映了栽培植物的形态结构，该形态结构包括枝干粗细、叶片大小等，不同种类的栽培植物在同一生长阶段的形态结构不同，在设置的时候需要根据实际情况进行选择。
102、根据栽培植物的种类信息，确定栽培植物的生长模型和营养液供给标准，营养液供给标准与生长模型的各个生长阶段对应。
控制装置根据栽培植物的种类信息确定生长模型和营养液供给标准，该营养液供给标准与生长模型的各个生长阶段的一一对应，确定不同的生长阶段栽培植物需要的营养液的供给量，即各个生长阶段的营养液供给标准。
103、按照预置的时间间隔判断栽培植物所处的目标生长阶段。
在种植设备中种植栽培植物后，按照预置的时间间隔判断栽培植物所处的目标生长阶段。例如，栽培植物的生长阶段可以分为幼苗期，成长期，成熟期等，还可以是其他的划分标准，具体此处不做限定。
104、根据目标生长阶段调整栽培植物的营养液供给量。
控制装置根据栽培植物所处的目标生长阶段，按照确定好的供给标准，调整需要向栽培植物输送的营养液供给量。不同的目标生长阶段对应不同的营养液供给量，具体的供给数量以确定好的营养液供给标准作为参考。
本发明实施例中，获取栽培植物的种类信息；根据栽培植物的种类信息，确定栽培植物的生长模型和营养液供给标准，营养液供给标准与生长模型的各个生长阶段对应；按照预置的时间间隔判断栽培植物所处的目标生长阶段；根据目标生长阶段调整栽培植物的营养液供给量。本发明实施例通过对栽培植物生长阶段的监控，按照预置的时间间隔判断栽培植物的实际生长阶段，再根据 预先确定好的营养液供给标准，向栽培植物提供营养液，实现营养液的科学配置，减少营养液的浪费，提高营养液的利用率。
请参阅图2，本发明实施例营养液的控制方法另一个实施例包括：
201、获取栽培植物的种类信息。
获取种植设备中栽培植物的种类信息，不同的植物种类对应的生长模型不同，生长模型反映了栽培植物的形态结构，该形态结构包括枝干粗细、叶片大小等，不同种类的栽培植物在同一生长阶段的形态结构不同，在设置的时候需要根据实际情况进行选择。不同种类的植物对应的生长模型不同，需要说明的是，不同的栽培植物可以有多种划分的标准，例如，能以品种为标准进行划分，如，芹菜、菠菜，也能以亚品种为标准进行划分，如，水芹、旱芹、西芹，还可以是其他的划分标准，具体此处不做限定。
202、根据栽培植物的种类信息，确定栽培植物的生长模型和营养液供给标准，营养液供给标准与生长模型的各个生长阶段对应。
控制装置根据栽培植物的种类信息确定生长模型和营养液供给标准，该营养液供给标准与生长模型的各个生长阶段的一一对应，确定不同的生长阶段栽培植物需要的营养液的供给量，即各个生长阶段的营养液供给标准。
203、按照预置的时间间隔获取栽培植物的目标图像。
在种植设备中种植栽培植物后，按照预置的时间间隔获取栽培植物目标图像。控制装置控制摄像头，每隔预置的时间间隔采集一次栽培植物的图像，即目标图像作为对比样本。
可以理解的是，为了保证采集的图像的质量，摄像头也可以多次采集图像，然后对采集的图像进行筛选，随机或按照预定的规则选择一张高质量的图像，将该图像确定为目标图像，具体采集次数可以按照实际需要进行设置。
需要说明的是，也可以按照预置的时间间隔获取栽培植物的种植天数。种植天数可以是人工主动输入，也可以是控制设备自己记录。
204、根据栽培植物的目标图像判断栽培植物所处的目标生长阶段。
控制装置根据栽培植物的目标图像与预置的对比图像进行匹配，对比图像与栽培植物的各个生长阶段一一对应；若目标图像与目标对比图像相似度达到预设值，则确定栽培植物处于目标对比图像对应的目标生长阶段。该预设值可 以是90％、80％，也可以是其他比例值，具体此处不做限定。
可以理解的是，栽培植物的生长阶段有多种划分方式，例如，可以分为幼苗期，成长期，成熟期等，还可以是其他的划分标准，具体此处不做限定。
需要说明的是，若控制装置获取的是栽培植物的种植天数，那么控制装置可以根据栽培植物的种植天数判断栽培植物所处的目标生长阶段。
205、比较当前营养液供给量与目标生长阶段对应目标供给标准。
控制装置检测当前营养液供给量，并且将检测到的数据与确定目标供给标准，该目标供给标准与目标生长阶段为一一对应关系。
206、根据目标生长阶段调整栽培植物的营养液供给量。
控制装置根据栽培植物所处的目标生长阶段，按照确定好的供给标准，调整需要向栽培植物输送的营养液供给量。若当前营养液供给量小于目标供给标准，则增加营养液供给量至目标供给标准；若当前营养液供给量大于目标供给标准，则减少营养液供给量至目标供给标准；若当前营养液供给量等于目标供给标准，则保持当前营养液供给量与目标供给标准相同。
可以理解的是，不同的目标生长阶段对应不同的营养液供给量，并且不同的栽培植物品种也会有明显差异，具体的供给数量可以根据确定好的营养液供给标准作为参考，该营养液供给标准综合考虑实际栽培过程和不同品种的栽培植物对营养液的吸收率。
本发明实施例中，获取栽培植物的种类信息；根据栽培植物的种类信息，确定栽培植物的生长模型和营养液供给标准，营养液供给标准与生长模型的各个生长阶段对应；按照预置的时间间隔获取栽培植物的目标图像；根据栽培植物的目标图像判断栽培植物所处的目标生长阶段；比较当前营养液供给量与目标生长阶段对应目标供给标准；根据目标生长阶段调整栽培植物的营养液供给量。本发明实施例通过对栽培植物生长阶段的监控，按照预置的时间间隔采集栽培植物的目标图像，根据该目标图像判断栽培植物的实际生长阶段，再根据预先确定好的营养液供给标准，减少、增加或保持栽培植物提供营养液至营养液供给标准，实现营养液的科学配置，减少营养液的浪费，提高营养液的利用率。
