In addition, alarm unit 20 is not limited to aforesaid way, for example also can be near each solar module M setting sound or light intimidate the unit, make the pairing cell operation of intimidateing in theft position come to avoid theft in advance through alarm unit 20.
The action of the theft monitoring arrangement 1 of solar module then, is described.
At first, in the setting of implementing to carry out before theft is kept watch on the first theft location tables 13 and the second theft location tables 14.At this moment, shown in Fig. 5 (a), under the state that makes open circuit/short circuit current 8 open circuits (opening), send pulse signal from the first input and output portion 6.So,, receive its reflected signal in the first input and output portion 6 through open open circuit/short circuit current 8 reflected impulse signals.Measuring the time T 0 from the transmission pulse signal to the reception reflected signal of this moment, is benchmark with the time T of measuring 0, carries out the setting of the first theft location tables 13 and the second theft location tables 14.
After this, make open circuit/short circuit current 8 short circuits (short), begin to steal the processing (below be called theft determination processing) of judgement.In the theft monitoring arrangement 1 of solar module; When solar module M is stolen, through the connecting portion 5 corresponding with this stolen solar module M with signal wire 4 electric cut-outs, therefore; Shown in Fig. 5 (b); When from the first input and output portion, 6 transmissions, first pulse signal,, receive i.e. first reflected signal of these signals that are reflected in the first input and output portion 6 through by connecting portion 5 reflections first pulse signal of electric cut-out.Measure this moment from sending first pulse signal to the time T 1 that receives first reflected signal; If with reference to the predefined first theft location tables 13, then can judge in stolen solar module M position (theft module numbering P1) near the solar module M of an end of ring circuit 2 with this time T 1.
And likewise, when from the second input and output portion, 7 transmissions, second pulse signal,, receive second reflected signal in the second input and output portion 7 through by connecting portion 5 reflections second pulse signal of electric cut-out.Measure this moment from sending second pulse signal to the time T 2 that receives second reflected signal; If with reference to the predefined second theft location tables 14, then can judge in stolen solar module M position (theft module numbering P2) near the solar module M of the other end of ring circuit 2 with this time T 2.
When a solar module M is stolen; Theft module numbering P1, P2 become identical numbering; But when a plurality of solar module M were stolen, theft module numbering P1, P2 became different numberings (P1<P2), can judge that solar module M is stolen in the scope of P1~P2.
Then, use Fig. 6, Fig. 7 to specify the control flow of theft determination processing.
As shown in Figure 6, in the theft determination processing, at first, through step S1, theft detection unit 10 sends first pulse signal from the first input and output portion 6, and after this, through step S2, the first theft location determination portion 11 starts timer T1.
In step S3, theft detection unit 10 judges whether receive first reflected signal in the first input and output portion 6.When in step S3, being judged to be " denying ", through step S4, theft detection unit 10 judges whether receive first pulse signal in the second input and output portion 7.Return step S3 when in step S4, being judged to be " denying ", when being judged to be " being ", advance to step S7.In step S7, it is not stolen that theft detection unit 10 is judged solar module M, advances to step S8.
When in step S3, being judged to be " being ", through step S5, to judge solar module M stolen for theft detection unit 10, after stealing location determination and handle through step S6, advances to step S8.
In step S8, the first theft location determination portion 11 is with timer T1 reset (reset).After this, return (returning step S1) after the standby schedule time through step S9.
In the theft location determination of step S6 is handled; As shown in Figure 7; At first through step S10, timer T1 measures in the first theft location determination portion 11, through step S11; Based on the predefined first theft location tables 13 (with reference to Fig. 3), judge theft module numbering P1 according to the timer T1 that in step S10, measures.
After this, through step S12, the second theft location determination portion 12 sends second pulse signal from the second input and output portion 7, and after this, at step S13, the second theft location determination portion 12 starts timer T2.
In step S14, the second theft location determination portion 12 judges whether receive second reflected signal in the second input and output portion 7.Repeating step S14 when in step S14, being judged to be " denying " advances to step S15 when being judged to be " being ".
In step S15, timer T2 measures in the second theft location determination portion 12.After this, through step S16,, judge theft module numbering P2 according to the timer T2 that in step S15, measures based on the predefined second theft location tables 14 (with reference to Fig. 4).
After this, through step S17, whether theft module numbering P1 that 15 judgements of theft location determination portion determine in step S11 and the theft module numbering P2 that in step S16, determines equate.When in step S17, being judged to be " being ", through step S18, theft location determination portion 15 will steal location determination for theft module numbering P1, advance to step S20.When in step S17, being judged to be " denying ", through step S19, theft location determination portion 15 will steal the scope of location determination for theft module numbering P1~P2, advance to step S20.
In step S20, the theft position that theft location determination portion 15 will determine in step S18 or S19 sends to alarm unit 20 as the theft position signalling.After this, through step S21, the second theft location determination portion 12 resets end process with timer T2.
The effect of this embodiment is described.
In the theft monitoring arrangement 1 of the solar module of this embodiment; With when solar module M is stolen through the mode looping circuit 2 of the connecting portion 5 corresponding with signal wire 4 electric cut-outs with this stolen solar module M; Send first pulse signal from an end of ring circuit 2; Distolateral receive of ring circuit 2 at ring circuit 2 internal reflections, first pulse signal and first reflected signal time; It is stolen to determine solar module M; And, according to getting time T 1 and judge the stolen solar module M position to receiving first reflected signal, and send second pulse signal from the other end of ring circuit 2 near the solar module M of an end of ring circuit 2 from sending first pulse signal; According to receiving the time T 2 of second reflected signal to the other end, judge in stolen solar module M position near the solar module M of the other end of ring circuit 2 at ring circuit 2 from sending second pulse signal.
Through formation like this, even can confirm also that when a plurality of solar module M are stolen solar module M might stolen scope or the stolen position of a plurality of solar module M.
In addition; The theft monitoring arrangement 1 of solar module is not the structure that as patent documentation 1, in ring circuit 2, flows through electric current all the time; But therefore every structure of sending first pulse signal at interval at a distance from preset time can suppress consumes electric power lower.
Then, other embodiment of the present invention is described.
The theft monitoring arrangement 81 of solar module shown in Figure 8, in the theft monitoring arrangement 1 of the solar module of Fig. 1, with connecting portion 5 that each solar module M is connected in be provided with for the unmatched reflecting element 5d of signal wire 4 impedances.Reflecting element 5d for example is made up of resistance, is set among the module side conducting wire 5c of module side connector 5b.
In the theft monitor module 81 of solar module, as shown in Figure 9, when the end from ring circuit 2 sent first pulse signal, the part of first pulse signal turned back to an end of ring circuit 2 successively through each reflecting element 5d reflection.First reflected signal that receives when stolen with solar module M through first reflected signal of this reflecting element 5d reflection is compared very little.Therefore, in the theft monitoring arrangement 81 of solar module, theft detection unit 10 is stolen if the signal intensity of first reflected signal that receives more than predetermined judgement is with threshold value, then determines solar module M.
And; In the theft monitoring arrangement 81 of solar module; Even do not measure from sending first pulse signal to the time T 1 that receives first reflected signal (judgement) with first reflected signal more than the threshold value; And to counting through first reflected signal of reflecting element 5d reflection; Count value that also can be when receiving said first reflected signal of judging with the signal intensity more than the threshold value is judged the position (among the solar module M near the position of the solar module M of an end of ring circuit 2) of stolen solar module M.As an example, in the example when the theft of Fig. 9, the 4th first reflected signal reached to be judged with the above signal intensity of threshold value, so theft module numbering P1 is 4.
About the second theft location determination portion 12 too; After the other end from ring circuit 2 sends second pulse signal; Second reflected signal to through reflected is counted; Count value during according to second reflected signal that receives than judge with the big signal intensity of threshold value judges among the stolen solar module M that the position near the solar module M of the other end of ring circuit 2 gets final product.
Therefore,, can omit the first theft location tables 13 or the second theft location tables 14, can make theft monitoring arrangement main body 3 become simpler structure through the theft monitoring arrangement 81 of solar module.In addition, through the theft monitoring arrangement 81 of solar module, all the time first reflected signal is counted, it is stolen to detect solar module M thus energetically, can improve reliability.
The present invention is not limited to above-mentioned embodiment, in the scope that does not break away from purport of the present invention, certainly carries out various changes.
For example; Explained in the above-described embodiment and on solar module M, connected connecting portion 5; Detect the stolen situation of solar module M; But according to the present invention, for example also can on each solar panel that constitutes solar module M, connect connecting portion 5, detect the stolen of solar panel.
