After this, by step S12, the second theft location determination portion 12 sends the second pulse signal from the second input and output portion 7, and after this, in step S13, the second theft location determination portion 12 starts timer T2.
In step S14, the second theft location determination portion 12 determines whether to receive the second reflected signal in the second input and output portion 7.Repeating step S14 when being judged to be "No" in step S14, proceeding to step S15 when being judged to be "Yes".
In step S15, the second theft location determination portion 12 measuring timer T2.After this, by step S16, based on the second theft position table 14 (with reference to Fig. 4) preset, judge theft module numbering P2 according to the timer T2 measured in step S15.
After this, by step S17, theft location determination portion 15 judges that whether the theft module numbering P1 that determines in step s 11 is equal with the theft module numbering P2 determined in step s 16.When being judged to be "Yes" in step S17, by step S18, theft location determination portion 15 will steal location determination for theft module numbering P1, proceed to step S20.When being judged to be "No" in step S17, by step S19, theft location determination is the scope of theft module numbering P1 ~ P2 by theft location determination portion 15, proceeds to step S20.
In step S20, the theft position determined in step S18 or S19 is sent to alarm unit 20 as theft position signalling by theft location determination portion 15.After this, by step S21, timer T2 resets by the second theft location determination portion 12, ends process.
The effect of present embodiment is described.
In the theft monitoring arrangement 1 of the solar module of present embodiment, with when solar module M is stolen by mode looping circuit 2 that signal wire 4 electrically cuts off by the connecting portion 5 corresponding with this stolen solar module M, the first pulse signal is sent from one end of ring circuit 2, when the end side of ring circuit 2 receives the first reflected signal obtained at ring circuit 2 internal reflection first pulse signal, determine solar module M stolen, and, according to the position obtaining time T1 from transmission first pulse signal to reception first reflected signal and judge closest to the solar module M of one end of ring circuit 2 in stolen solar module M, and send the second pulse signal from the other end of ring circuit 2, according to the time T2 receiving the second reflected signal from transmission second pulse signal to the other end at ring circuit 2, judge in stolen solar module M closest to the position of the solar module M of the other end of ring circuit 2.
By formation like this, even if also can determine the scope that solar module M is likely stolen or the stolen position of multiple solar module M when multiple solar module M is stolen.
In addition, the theft monitoring arrangement 1 of solar module is not the structure flowing through electric current as described in Patent Document 1 all the time in ring circuit 2, but the structure of the first pulse signal is sent every predetermined time interval, therefore can power consumption be suppressed lower.
Then, other embodiment of the present invention is described.
The theft monitoring arrangement 81 of the solar module shown in Fig. 8, in the theft monitoring arrangement 1 of the solar module of Fig. 1, is provided with the reflecting element 5d for signal wire 4 impedance mismatch in the connecting portion 5 be connected with each solar module M.Reflecting element 5d is such as made up of resistance, is arranged in the module side conducting wire 5c of module side connector 5b.
In the theft monitoring module 81 of solar module, as shown in Figure 9, when sending the first pulse signal from one end of ring circuit 2, a part for the first pulse signal is reflected by each reflecting element 5d, turns back to one end of ring circuit 2 successively.Very little compared with the first reflected signal that the first reflected signal reflected by this reflecting element 5d is received time stolen with solar module M.Therefore, in the theft monitoring arrangement 81 of solar module, if the signal intensity of the first reflected signal that theft detection unit 10 receives is more than predetermined judgement threshold value, then determine solar module M stolen.
And, in the theft monitoring arrangement 81 of solar module, even if do not measure the time T1 from transmission first pulse signal to reception first reflected signal (the first more than judgement threshold value reflected signal), and the first reflected signal reflected by reflecting element 5d is counted, also according to count value when receiving described first reflected signal of signal intensity of more than judgement threshold value, the position (closest to the position of the solar module M of one end of ring circuit 2 in solar module M) of stolen solar module M can be judged.As an example, in the example when the theft of Fig. 9, the 4th the first reflected signal reaches the signal intensity of more than judgement threshold value, so theft module numbering P1 is 4.
About the second theft location determination portion 12 too, after sending the second pulse signal from the other end of ring circuit 2, the second reflected signal reflected by reflecting element is counted, according to count value when receiving the second reflected signal of the signal intensity larger than judgement threshold value, judge the position closest to the solar module M of the other end of ring circuit 2 in stolen solar module M.
Therefore, by the theft monitoring arrangement 81 of solar module, the first theft position table 13 or the second theft position table 14 can be omitted, theft monitoring arrangement main body 3 can be made to become simpler structure.In addition, by the theft monitoring arrangement 81 of solar module, all the time the first reflected signal is counted, can detect that solar module M is not stolen, can improve reliability thus energetically.
The present invention is not limited to above-mentioned embodiment, certainly can carry out various change without departing from the spirit and scope of the invention.
Such as, describe in the above-described embodiment and connect connecting portion 5 on solar module M, detect the stolen situation of solar module M, but according to the present invention, such as also can connect connecting portion 5 on each solar panel forming solar module M, detect the stolen of solar panel.
