The purpose of this utility model provides that a kind of to take stock number little, especially less to the occupancy of exchange line resource, to reduce the cost of whole network, can not only report to the police to the open circuit conditions of circuit, and can also make the addressable communications anti-theft alarm for cable of warning the situation of short circuit.
Of the present utility model being characterised in that comprises signal received code processor, rectifier D, at least one route road signal detector and decoding processor,
Described signal received code processor is provided with the signal receiving end d1～dn more than or equal to the line signal detector number, a signal output part and the input end A1～An that encodes, and signal output part is provided with signal amplifier;
Described signal detector is provided with a signal receiving end and a signal output part, its signal output part inserts among the signal receiving end d1～dn of signal received code processor, be provided with signal amplifier before the signal receiving end and between the signal output part, be provided with pull-up resistor Rf in the voltage circuit of signal receiving end;
Decoding processor is provided with one road signal receiving end and alarm signal output ends B1～Bn, and the signal receiving end front end is provided with phase inverter, and this decoding processor also is provided with coding input end A '～An ';
Rectifier D is located between scrambler IC1 and the signal processor IC2.
Compared with prior art, it is little that the utility model takies stock number, especially less to the occupancy of exchange line resource, during system group network, each bar outgoing cable is to only taking a pair of cable between the cross-connecting box, can finish monitoring to all distribution cables in this cross-connecting box, greatly reduce the cost of whole network, can not only report to the police, and can also make warning the situation of short circuit to the open circuit conditions of circuit, the extension address sign indicating number can be by in the preceding setting of deploying troops on garrison duty, and is safe and reliable.
Below in conjunction with accompanying drawing the utility model is described.
Accompanying drawing is the circuit diagram of an embodiment of the utility model.
With reference to accompanying drawing, the utility model comprises signal received code processor (2), rectifier D, at least one route road signal detector (1) and decoding processor (5).
Described signal received code processor is provided with the signal receiving end d1～dn more than or equal to the line signal detector number, a decoded signal output terminal and the input end A1～An that encodes, coding input end A1～A10 can be to the coding of the control chip IC1 of signal received code processor incoming line signal detector d1～dn, and the signal output part of signal received code processor is provided with signal amplifier (3).
