本发明公开一种光伏空调系统的性能检测方法，能够缩短检测时间，并提高检测结果的准确度。
参见图1，图1为本发明公开的一种光伏空调系统的性能检测方法的流程图。本发明中将光伏空调系统划分为多个子系统，每个子系统包括多个待检部件。该方法应用于光伏空调系统的性能检测装置，包括：
步骤S1：分别获取各子系统中待检部件的运行状态信息。
性能检测装置与各个子系统连接，能够获取各个待检部件的运行状态信息。这里需要说明的是，待检部件的运行状态信息为开关量信息或者模拟量信息。具体的，开关型部件的运行状态信息为开关量信息，模拟量型部件的运行状态信息为模拟量信息(一个数值)。
待检部件的运行状态信息可从各子系统的控制器中获得。各子系统的控制器与相应子系统内的待检部件连接，或与用于检测待检部件运行状态的传感器通信连接，以获取待检部件的运行状态、输出控制指令。
对于已经具备运行状态信息反馈功能的待检部件，或已自带通讯接口和传感器、具有运行状态信息输出功能的待检部件，性能检测装置可直接与各子系统的控制器通讯连接，性能检测装置从各子系统的控制器中获得相关运行状态信息。
对于自身运行状态信息反馈功能不足的待检部件，或自带传感器类型或数量不足的待检部件，或不具有运行状态信息反馈功能的待检部件，则根据实际检测需求在适当的位置布置传感器，并将布置的传感器与各子系统的控制器通讯连接，以便性能检测装置从各子系统的控制器中获得相关运行状态信息。
例如：系统中的部分阀门类部件只有导通和关闭两个工作状态，则阀门类部件的运行状态信息为开关量信息，包括导通和关闭两个运行状态信息；系统中的压缩机的运行状态信息包括运行频率信息(为一数值)、电机温度信息，即为模拟量信息，空调主机系统的控制器可以从压缩机获取这些信息并传输给性能检测装置；系统中的风机的运行状态信息包括转速信息，该转速信息也为模拟量信息。
步骤S2：根据预设的部件的运行状态信息和性能分数的对应关系，分别确定各个待检部件的性能分数。
性能检测装置中预存有各个部件的运行状态信息和性能分数的对应关系。对于开关型部件，其运行状态信息仅包括第一状态信息和第二状态信息，相应的，开关型部件的运行状态信息和性能分数的对应关系包括：第一状态信息和对应的性能分数，第二状态信息和对应的性能分数。对于模拟量型部件，其运行状态信息为一个运行参数值，相应的模拟量型部件的运行状态信息和性能分数的对应关系包括：多个运行参数值区段和对应的性能分数。在获取待检部件的运行状态信息后，就可以根据预设的部件的运行状态信息和性能分数的对应关系，确定该待检部件的性能分数。
步骤S3：分别确定各个子系统的性能分数。其中，一个子系统的性能分数由该子系统所包含的待检部件的性能分数确定。
实施中，一个子系统的性能分数可以为该子系统所包含的各个待检部件的性能分数之和。确定子系统的性能分数的过程包括：计算子系统所包含的待检部件的性能分数的和值；确定该和值为该子系统的性能分数。
步骤S4：确定光伏空调系统的性能分数S，
Figure PCTCN2015085364-appb-000005
其中，s(i)为第i个子系统的性能分数，k(i)为第i个子系统的权重，n为子系统的数量。
在确定各个子系统的性能分数之后，就可以确定光伏系统的性能分数S。这里需要说明的是，各个子系统的权重之和为1，子系统的权重依据该子系统对光伏空调系统正常运行所产生的影响确定。
本发明公开的光伏空调系统的性能检测方法，在获取待检部件的运行状态信息后，利用预设的部件的运行状态信息和性能分数的对应关系，确定待检部件的性能分数，之后利用待检部件的性能分数确定子系统的性能分数，之后利用各个子系统的性能分数确定光伏空调系统的性能分数，完成对光伏空调系统的性能检测。基于本发明公开的性能检测方法，性能检测装置直接获取待检部件的运行状态信息，无需进行人工数据采集和汇总，因此可以缩短检测时间，另外，性能检测装置自动计算各子系统以及光伏空调系统的性能分数，不会出现计算误差，可以提高检测结果的准确度。
实施中，还可以采用其他方式确定子系统的性能分数，例如：获取子系统中各个待检部件的权重；利用公式
