It is stored in storage unit 11.The time label for indicating time date of formation of measured value is attached in this measured value.That is, measured value
During the segmentation being generated with information at the time of (generating the moment) at the time of indicating that measured value is generated and expression measured value
Period information establishes correspondence.Moreover, storage unit 11 has accumulated the measured value of additional having time label.
Presumption unit 14 estimates the meteorology of the setting position of multiple solar panels 2.For example, presumption unit 14, utilizes
The measurement insolation amount for the result that pyranometer 4 measures, to estimate the meteorology that position is arranged of solar panel 2.
Pyranometer 4 is arranged on the roof of the building equipped with multiple solar panels 2, is arranged in 1 year
Any one season and daytime any moment, the shadow that will not be constructed object and plant hides residence.Moreover, day
Penetrate intensitometer 4, the insolation amount of the setting position of measurement pyranometer 4, when adding on measuring insolation amount indicates the measurement date
Between time label, and be sent to monitoring arrangement 1.
Presumption unit 14, by solar panel 2 setting position meteorology and be arranged with 2 phase of solar panel
It is considered as with the meteorology of the setting position of the pyranometer 4 in place identical, solar energy is estimated according to measurement insolation amount
The meteorology of the setting position of solar panel 2.Specifically, presumption unit 14, is counted via communication unit 12 from pyranometer 4
Insolation amount is surveyed, by comparing the measurement insolation amount and preset benchmark insolation amount, to estimate setting for solar panel 2
The meteorology of seated position.
Benchmark insolation amount compared with measuring insolation amount is to cover the fine day of pyranometer 4 in the shadow of not cloud
In the case where, it can be preset by the presumed value for the insolation amount that pyranometer 4 measures according to estimation.
Presumption unit 14, in the case where actual measurement insolation amount is benchmark insolation amount or more, by solar panel 2
The meteorology that position is arranged is estimated as being fine day.In addition, presumption unit 14, is less than benchmark insolation amount in actual measurement insolation amount
In the case where, the meteorology of the setting position of solar panel 2 is estimated as not to be fine day (such as cloudy day or rainy day).This
In described fine day refer to, the meteorology that solar panel 2 is not covered by the shadow of cloud.
In this way, presumption unit 14 obtains the measurement insolation amount that attached time label, according to the measurement insolation amount of acquisition, presumption
The meteorology of the setting position of solar panel 2.Moreover, presumption unit 14, by the presumption result of meteorology be attached to
The time label for measuring insolation amount, which is established, to be corresponded to, and storage unit 11 is stored in.Therefore, the presumption of meteorology is accumulated in storage unit 11
As a result, establishing corresponding presumption result with time label.
In addition, the benchmark insolation amount compared with measuring insolation amount, it can be according to the longitude and latitude of the setting position of pyranometer 4
Degree and measurement date-time etc. and be corrected.
Judging part 15 compares the measured value (generation power measured value) and a reference value (generation power stored in storage unit 11
A reference value), abnormal judgement processing is carried out, which judges that processing is to judge whether the output of solar panel 2 is normally sentenced
Disconnected processing.For example, judging part 15, carries out abnormal judgement processing, such as in the regulation moment (such as) of post sunset, benefit at 21 points daily
With the measured value of the same day (judging object day), abnormal judgement processing is carried out.
In order to carry out exception judgement processing, judging part 15 is extracted from storage unit 11 for the abnormal benchmark for judging processing
Value and measured value.Specifically, judging part 15, from the multiple a reference values for being stored in storage unit 11, the base of extraction comparison object
Quasi- value, i.e., with a reference value corresponding during judging segmentation belonging to object day.
Moreover, it is judged that portion 15, confirms the time label for each measured value stored in storage unit 11, sentences from the extraction of storage unit 11
The more than one measured value of disconnected object day.Moreover, judging part 15 one for judging object day extracted from storage unit 11 with
On measured value in, the more than one measurement that is generated at the time of extracting corresponding with the insolation moment of a reference value of comparison other
Value.Here, the insolation moment with a reference value refers at the time of corresponding, from the day not covered by shadow as solar panel 2
It penetrates moment and a reference value and establishes the corresponding insolation moment and start phase until before the stipulated time (for example, before 1 hour)
Between in comprising at the time of.That is, it is judged that the extraction of portion 15 was covered in the shadow that solar panel 2 is not constructed object and plant etc.
The more than one measured value that moment generates.
In turn, judging part 15 confirm the meteorology and its time label that presumption unit 14 estimates with reference to storage unit 11,
And confirms and judge that meteorology that object day estimates is the period (after, referred to as fine day period) of fine day.Moreover, judgement
From the more than one measured value being extracted, that extracts measured value generates the moment included in the measurement of fine day period in portion 15
Value.
That is, it is judged that portion 15, which extracts the shadow in structure and plant etc., does not cover solar panel 2 and cloud
Shadow do not cover the measured value generated at the time of solar panel 2.
In this way, judging part 15 extracts and a reference value corresponding during judging segmentation belonging to object day from storage unit 11.Into
And judging part 15 extracts the insolation moment pair for generating moment and a reference value in the more than one measured value for judging object day
Answer and be included in the measured value of fine day period.Moreover, judging part 15, a reference value being extracted by comparing be extracted
Measured value, to carry out abnormal judgement processing.
That is, it is judged that portion 15, the setting position by comparing solar panel 2 is the meter that the date-time of fine day is generated
Measured value and a reference value corresponding with information during the measured value and time information, to carry out abnormal judgement processing.
In addition, in the case where the measured value for being extracted multiple comparison others, judging part 15 will be extracted for 1 a reference value
The average value of multiple measured values be compared with a reference value.In addition, during judging segmentation belonging to object day with insolation when
It carves different multiple a reference values to establish in corresponding situation, judging part 15 extracts all a reference values, and then to each benchmark
Value extracts the measured value for becoming comparison other.Moreover, a reference value is established with measured value 1 to 1 corresponding and compared by judging part 15
Compared with.
Judging part 15 is compared a reference value and measured value of extraction, in the case where measured value is a reference value or more,
It is judged as and judges that the output of the solar panel 2 of object is normal.Moreover, it is judged that portion 15, is less than a reference value in measured value
In the case of, it is judged as and judges that the output of the solar panel 2 of object is abnormal.Judging part 15 can also judge in this way, count
Measured value is less than the number of a reference value, in the case where continuously there is defined number, has additional mark in measured value for constituting
Number the solar panel 2 of string 20 be judged as abnormal.
Transmission unit 16, the judging result for the abnormal judgement processing that judging part 15 is carried out, such as sent via communication unit 12
To general PC, that is, external device (ED) 5.External device (ED) 5 by the judging result of received abnormal judgement processing, such as is shown
In liquid crystal display, that is, display unit 51, whether the output for informing the user solar panel 2 is normal.
Fig. 2 is the master's concept map to be processed for indicating monitoring arrangement 1 shown in fig. 1.Monitoring arrangement 1 as shown in Figure 2, obtains
Measured value (generation power measured value).Moreover, monitoring arrangement 1, compares measured value and is stored in the storage unit 11 of monitoring arrangement 1
A reference value (generation power a reference value), to judge that solar panel 2 is normal or abnormal.Moreover, monitoring arrangement 1,
External device (ED) 5 is sent by normal or abnormal judging result.
In the following, using the flow chart that Fig. 3 is indicated come specification exception judgement processing.
Judging part 15 executes abnormal judgement processing at the preset regulation moment.First, it is determined that portion 15, from storage unit
11 extract and a reference value corresponding during judging segmentation belonging to object day (generation power a reference value) (S1).Next, it is determined that portion
15, in the resume for the more than one measured value (generation power measured value) for judging object day, meter is extracted from storage unit 11
The generation moment more than one measured value (S2) corresponding with the insolation moment of a reference value of measured value.In turn, judging part 15, confirmation
In the more than one measured value of extraction, if having measured value generates the moment included in the measured value of fine day period
(S3)。
Judging part 15 has the generation moment of measured value to be included in the fine day time in the more than one measured value of extraction
In the case where the measured value of section ("Yes" in S3), that extracts measured value generates the moment included in the measured value of fine day period
(S4).Moreover, 15 pairs of the judging part a reference values extracted and measured value are compared (S5).
Judging part 15 judges solar panel 2 in the case where measured value is a reference value or more ("Yes" in S5)
Export normal (S6).On the other hand, judging part 15 are judged as in the case where measured value is less than a reference value ("No" in S5)
The output abnormality (S7) of solar panel 2.In addition, in the more than one measured value of extraction, not generating electricity in step S3
Electric power generate the moment be included in the fine day period measured value in the case where ("No" in S3), then terminate at abnormal judgement
Reason.
In addition, establishing during judging segmentation belonging to object day from multiple a reference values at different insolation moment corresponding
In the case of, handled using the abnormal judgement of following a reference value.
In this way, the monitoring arrangement 1 of present embodiment, measured value when solar panel 2 is not covered by shadow and
It is generation power presumed value in normal situation according to solar panel 2 and a reference value that sets is compared, thus into
Row exception judgement processing.That is, measured value, Yi Jiyun when covering solar panel 2 in addition to the shadow of structure or plant
The more than one measured value other than measured value when color shadow covers solar panel 2, for abnormal judgement processing.
Therefore, in monitoring arrangement 1, distinguish because shadow influence caused by solar panel 2 generation power decline,
Decline with the generation power of solar panel 2 caused by the failure because of solar panel 2.In this way, monitoring arrangement 1 is in the sun
When the abnormality detection of energy solar panel 2, it is able to suppress error detection caused by the influence because of shadow.That is, monitoring arrangement 1, is able to suppress
