在一种可能的实施方式中，本公开实施例的第二目标照度可以是根据等值黑视素照度(EML，Equivalent Melanopic Lux)得到的，从而实现基于健康需求对照明系统的各个照明单元的照度的调整。
请参阅图2，图2示出了根据本公开一实施例的人的视觉系统和节律刺激系统的敏感度曲线的示意图。
在一个示例中，如图2所示，视觉任务的需求通过照度来衡量，而节律刺激的健康需求可通过等值黑视素照度进行衡量。本公开实施例利用敏感度曲线和人眼处的光谱分布可得到等值黑视素照度(EML)和照度(L)之间的转化系数(R)，即EML＝R*L。一般对于办公场景，视觉任务要求提供300lux的桌面照度，节律刺激要求在预设时间段(如9：00-13：00时段)人眼处达到200EML，该要求可作为健康照明时第二目标照度的默认值。

在一个示例中，如图3a及图3b所示，照明单元(照明设备)可以设置在办公区域的顶部。
当然，以上对照度传感器、照明设备等安装方式的介绍是示例性的，不应视为是对本公开实施例的限定，在其他实施例中，照度传感器可以有其他的安装方式，例如可以安装在天花板上，也可以朝向采光窗，直接测量自然采光。对于天花板和朝向采光窗的安装形式，日光提供的照度可根据房间参数由相关技术进行计算。

在一个示例中，照明单元i在目标区域(如工位)j的桌面和人眼处提供的照度和当前时刻照明单元的照明参数(如档位)D i,τ成正比，第一预设参数及第二预设参数分别为k ij， z(桌面照度-档位的系数)和k ij，y(人眼照度-档位的系数)，其中，i、j均为整数。本公开实施例第一预设参数及第二预设参数的大小不做限定，本领域技术人员可以根据实际情况设置，例如可以通过模拟计算或实测的方式得到。
在一个示例中，照明单元i在工位j处的第一位置提供的灯光照度可为第一预设参数与当前照明参数之积，即k ij，z*D i,τ，照明单元i在工位j处的第二位置提供的灯光照度可为第二预设参数与当前照明参数之积，即k ij，y*D i，τ，其中，τ表示时刻，D i，τ表示照明单元i在当前时刻τ的照明参数，D i，τ+1表示照明单元i在时刻τ+1的照明参数，通过本公开实施例的照度控制方法，可以得到下一时刻的照明参数，以满足正常工作照度需求，并符合健康管理、节能的需求。
在一个示例中，在各个工位j处，多个照明单元在第一位置提供的第一灯光照度L′ jz,τ可以如公式1所示：
Figure PCTCN2021137882-appb-000001
其中，m表示照明单元的总数目。
在一个示例中，在各个工位j处，多个照明单元在第二位置提供的第二灯光照度L′ jy,τ可以如公式2所示：

在一个示例中，步骤S11获取的第一采集照度、第二采集照度可以分别记为L jz,τ和L jy,τ。当前时刻τ自然光在工位(j)的第一位置提供的第一自然光照度记为S jz,τ，当前时刻τ自然光在工位(j)的第二位置提供的第二自然光照度记为S jy,τ，自然光在工位j处提供照度可以为检测得到的总照度减去照明单元提供照度，即，
在一个示例中，可以根据所述第一采集照度及所述第一灯光照度之差确定所述第一自然光照度，如公式3所示：
S jz,τ＝L jz,τ-L′ jz,τ   公式3
在一个示例中，可以根据所述第二采集照度及所述第二灯光照度之差确定所述第二自然光照度，如公式4所示：
S jy,τ＝L jy,τ-L′ jy,τ   公式4
在一个示例中，照度(L)和等值黑视素照度(EML)均具有可叠加性，即对于多个光源，照度可由公式5确定，等值黑视素照度可由同时6确定：
L＝∑L i   公式5
EML＝∑(R i*L i)   公式6
在一个示例中，由于自然光和灯光的光谱分布可认为不变，自然光的转化系数(Rs)和灯光的转化系数(Ri)可以根据光谱特性预先进行设定。对于灯光光谱变化的情况，可以根据图2所示的敏感度曲线计算出变化后光谱的转化系数Ri，当然，本公开实施例对转化系数的具体确定方式及转化系数的具体大小不做限定，本领域技术人员可以根据需要及实际情况确定。
在一种可能的实施方式中，步骤S13根据所述第一位置的第一目标照度及所述第一自然光照度确定各个照明单元的目标照明参数，可以包括：
根据第一条件确定各个照明单元的目标照明参数，
所述第一条件包括：各个照明单元在各个目标照明参数的作用下在所述第一位置的灯光照度及所述第一自然光照度之和大于或等于所述第一目标照度。

根据第二条件确定各个照明单元的目标照明参数，
所述第二条件包括：各个照明单元在各个目标照明参数的作用下在所述第一位置的灯光照度及所述第一自然光照度之和大于或等于所述第一目标照度，且，各个照明单元在各个目标照明参数的作用下在所述第二位置的灯光照度及所述第二自然光照度之和大于或等于所述第二目标照度。
在一个示例中，第一条件可以如公式7所示，第二条件可以如公式7和公式8所示。
∑(k ij，z*D i,τ+1)+S jz,τ≥L j    公式7
∑(R i*k ij，y*D i,τ+1)+R s*S jz,τ≥EML j   公式8
对于不同的时间段，本公开实施例可以分别根据以上方法确定各个照明单元的目标照明参数，例如，对于预设时间段之外，可以不考虑人眼处的照度影响，因此根据第一条件确定各个照明单元的目标照明参数，而对于预设时间段之内，需要同时考虑人眼处的照度影响，因此，本公开实施例在该情况下根据第二条件确定各个照明单元的目标照明参数。
在一种可能的实施方式中，本公开实施例可以求解公式7或，求解公式7和公式8，以得到多组照明单元的目标照明参数，在这种情况下，本公开实施例可以以各个照明单元的照明参数之和最小为约束条件(Min∑D i,τ+1)，确定各个照明单元的目标照明参数，即，在求解公式7或，求解公式7和公式8，可能会得到多组目标照明参数满足公式7或，满足公式7和公式8，由于灯具的功率和档位成正比，因此为了使得照明系统的能耗最低，本公开实施例选择各个照明单元的照明参数之和最小的一组照明参数为目标照明参数。
在一种可能的实施方式中，如图4所示，所述方法还可以包括：
步骤S10，配置所述第一目标照度和/或所述第二目标照度。

本公开实施例可以根据多种方式配置第一目标照度、第二目标照度，以提高照明系统控制的环境适应性、灵活性。
下面对步骤S10配置所述第一目标照度和/或所述第二目标照度进行示例性介绍。
请参阅图5，图5示出了根据本公开一实施例的照度控制方法的示意图。
在一个示例中，如图5所示，工作人员可以通过遥控器、触控面板、手机app等方式对第一位置和/或第二位置的第一目标照度、第二目标照度进行设定，由于工作人员可能在任何时段对任何工位的照度进行主观设定，因此本公开实施例首先判断每一个工位是否有人员设定。
在一个示例中，如图5所示，对于有设定的工位(Aj＝1)，第一位置和/或第二位置的第一目标照度、第二目标照度可以为人员设定值，保证不同光照偏好个体的满意度。若没有设定，则继续进行下一步判断。
在一个示例中，如图5所示，对没有设定的工位(Aj＝0)，判断人员是否在位，人员是否在位可通过但不限于人体传感器进行判断(例如通过NFC卡、WiFi等定位方式、人脸识别、人体识别等方式)等
在一个示例中，如图5所示，对于每一个工位，若人员不在位(Bj＝0)，则该工位桌面应提供背景照明的照度，保证室内光环境的均匀性。例如在位时的工位桌面默认照度为300lux，则可设定不在位的背景照明默认照度为100lux(第一预设目标照度)，保证人眼舒适度的同时，达到节能的效果。
在一个示例中，如图5所示，对于人员在位的工位(Bj＝1)，进一步判断当前时间是否在预设时间段(如9：00-13：00)内。若不在此时段内(Cj＝0)，则工位的桌面照度为工作照明默认值，例如设置桌面工作照明默认照度为300lux。
在一个示例中，如图5所示，若当前时间在预设时间段(Cj＝1)，则该工位的桌面和 人眼照度采取健康照明的默认值，例如设置桌面照度为300lux且人眼处等值黑视素照度为200EML。
通过以上方式，本公开实施例可以根据多种情况配置所述第一目标照度和/或所述第二目标照度，以提高照明系统的控制的灵活性。

这些计算机可读程序指令可以提供给通用计算机、专用计算机或其它可编程数据处理装置的处理器，从而生产出一种机器，使得这些指令在通过计算机或其它可编程数据处理装置的处理器执行时，产生了实现流程图和/或框图中的一个或多个方框中规定的功能/动作的装置。也可以把这些计算机可读程序指令存储在计算机可读存储介质中，这些指令使得计算机、可编程数据处理装置和/或其他设备以特定方式工作，从而，存储有指令的计算机可读介质则包括一个制造品，其包括实现流程图和/或框图中的一个或多个方框中规定的功能/动作的各个方面的指令。
也可以把计算机可读程序指令加载到计算机、其它可编程数据处理装置、或其它设备上，使得在计算机、其它可编程数据处理装置或其它设备上执行一系列操作步骤，以产生计算机实现的过程，从而使得在计算机、其它可编程数据处理装置、或其它设备上执行的指令实现流程图和/或框图中的一个或多个方框中规定的功能/动作。
附图中的流程图和框图显示了根据本公开的多个实施例的系统、方法和计算机程序产品的可能实现的体系架构、功能和操作。在这点上，流程图或框图中的每个方框可以代表一个模块、程序段或指令的一部分，所述模块、程序段或指令的一部分包含一个或多个用于实现规定的逻辑功能的可执行指令。在有些作为替换的实现中，方框中所标注的功能也可以以不同于附图中所标注的顺序发生。例如，两个连续的方框实际上可以基本并行地执行，它们有时也可以按相反的顺序执行，这依所涉及的功能而定。也要注意的是，框图和/或流程图中的每个方框、以及框图和/或流程图中的方框的组合，可以用执行规定的功能或动作的专用的基于硬件的系统来实现，或者可以用专用硬件与计算机指令的组合来实现。
该计算机程序产品可以具体通过硬件、软件或其结合的方式实现。在一个可选实施例中，所述计算机程序产品具体体现为计算机存储介质，在另一个可选实施例中，计算机程序产品具体体现为软件产品，例如软件开发包(Software Development Kit，SDK)等等。
以上已经描述了本公开的各实施例，上述说明是示例性的，并非穷尽性的，并且也不限于所披露的各实施例。在不偏离所说明的各实施例的范围和精神的情况下，对于本技术领域的普通技术人员来说许多修改和变更都是显而易见的。本文中所用术语的选择，旨在最好地解释各实施例的原理、实际应用或对市场中的技术的改进，或者使本技术领域的其它普通技术人员能理解本文披露的各实施例。
