Embodiment
Embodiment one
It is as shown in Figure 1 that the thing of present embodiment joins bus-bar system, and the patch case of bus top 2 on bus main line and bus branch line that draws from low-tension switch cabinet 1 (also can be transformer or jack box) power supply is connected to each user side.U1, U2, U3, Un are bus branch line terminal among the figure.The user can patch from each bus branch line and draw.Bus main line G and bus branch line B are respectively by adjacent bus bulk---and comprise that straightway and elbow are electrically connected through connector 3, and be fixedly mounted on building or the auxiliary part through installed part 4.Bus branch line B is electrically connected with bus main line G through jack box 5.As shown in Figure 2, join bus-bar system in order to form thing, at bus top 2, bus bulk (comprising straightway and elbow), connector 3, jack box 5, installed part 4 places respectively need monitoring place to be mounted with corresponding transducer respectively.These transducers join the corresponding port connection of access device respectively through holding wire and thing; And the PORT COM of thing couplet access device is connected (its operational process is referring to Fig. 5) with the webserver communication that joins manager as thing, and then is connected with subscriber computer or hand-held mobile communication equipment communication through the Internet.
