供給している。Background of the Technology Conventionally, in unmanned telemeter observation stations, as shown in Figure 1, the output from a solar cell SB, which is made up of a plurality of cells CEI to CE7 connected in series, is connected to an alkaline battery BT via a backflow prevention diode D. It supplies a voltage of 12V to the load while charging.
ここで太陽電池に障害が発生するとアルカリ電池への充
電、負荷への電圧供給が停止するので、これを検出する
必要がある。If a failure occurs in the solar cell, charging to the alkaline battery and voltage supply to the load will stop, so it is necessary to detect this.

メータ観測局では５日〜１ケ月程度のバッテリー容量が
あるため検出までかなりの時間がかかる。Conventional technology and problems Conventionally, the output of alkaline batteries has been monitored in order to detect failures in solar cells, but according to this method, unmanned telemeter observation stations have a battery capacity of about 5 days to 1 month, so detection is difficult. It takes quite a while.
又障害が検出された時バッテリーはほとんど放電してい
るので、テレメータが動作停止してしまう欠点があった
。Furthermore, since the battery is almost discharged when a fault is detected, there is a drawback that the telemeter stops operating.

方式によって達成される。Structure of the Invention In a solar cell made up of a plurality of cells connected in series, the output of any one cell is compared with the output of other cells using a comparator, and the difference in output is detected by the comparator. This is achieved by a solar cell failure detection method that outputs an alarm at certain times.
