Embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Structure as shown in Figure 1, this correction instrument belongs to a kind of electrical part, and adopt two single-chip microcomputers to form two terminals, one is transmitter 1, and another is receiver 2.Transmitter 1 core devices is a single-chip microcomputer 1, single-chip microcomputer 1 has multiple Wiring port J1, J2 ... Jn.Each port can connect a wire of polycore cable respectively, if mark wire size is 1,2 ... the wire of n, consistent with connected wire wire size to the numbering of each port.

Receiver 2 core devices is also a single-chip microcomputer 2 21, single-chip microcomputer 2 21 there are two Wiring ports, in receiver, be provided with power supply (battery), correspondence is connected to these two ports of receiver, these two ports can be used as positive and negative electrode, externally can connect positive and negative electrode two wires.

Utilize the conductive characteristic of tested cable, the power supply synchronous applications in receiver can be used in transmitter, power supply, by the powered battery of receiver, does not have power supply in transmitter, and only when transmitter is connected with receiver, the circuit of transmitter could work.Can battery be changed like this, need not power operation be opened or closed, avoid forgetting and open or close power operation, make more convenient to use, one of peculiar design belonging to this device.

In order to the function that wire can be made to possess power lead, so we are when utilizing wire to form electricity consumption loop, need to arrange the contrary diode 3 and 4 (each Wiring port has two terminals) of two conducting directions at two terminal places of cable port and each Wiring port of single-chip microcomputer 1, the diode in a direction holds (i.e. positive source) to be connected with single-chip microcomputer one 11VCC, and the diode in another direction holds (i.e. power cathode) to be connected with single-chip microcomputer one 11GND.Like this when the both positive and negative polarity of power supply is connected on certain two wire in cable, by the diode circuit on these two wires and circuit, and the VCC of two single-chip microcomputers holds and GND end, just power circuit can be formed, electric current flows to transmitter from the wire at the diode place being connected with forward conduction, then returns receiver from the wire being connected with reverse conduction diodes place.

In order to make the outside signal transmission of wire, we can adopt the form of different current pulse signal to send.In order to differentiate the size of electric current, be provided with the current detection circuit be made up of transistor 5, resistance 7 in receiver, the output of testing circuit, after receiver receives, shows on the display 6, or send out with the form of voice broadcast can.

As can be seen here, all wires of cable are all numbered with wire size in transmitter one end, as adopted all enforceable Native digits numbering of those skilled in the art, 1,2,3 ... n, the each port of transmitter is sent to receiver by the form of different pulsed current signals, enters mark belong to proven technique with different pulse currents to signal.Then, after receiver receives signal, by the conversion of electric signal to digital signal, will obtain numbering consistent numerical information with wire, so just the two ends of a wire can be proofreaded.Single-chip microcomputer 1, single-chip microcomputer 2 21 use matured product on market all can realize above-mentioned numbering function, such as adopt 51 single-chip microcomputers.
