Description

A kind of method for quickly identifying of electrical transmission wires and system thereof

Technical field

The present invention relates to a kind of method for quickly identifying and system thereof of lead.

Background technology

In traditional passenger vehicle wire harness, the method for existing mark wire size is mainly by following two kinds: 1. wire size is beaten in advance on the wire size pipe, be enclosed within then near on the lead of plug connector, the two ends of every lead all can put such wire size pipe like this; 2. on lead, beat wire size, on lead, just have a wire size like this every a segment distance.Comprehensive above-mentioned two kinds of methods, all can realize identification to traditional wire harness, reach the purpose of distinguishing wire harness, but part unavoidably comes with some shortcomings simultaneously: for first method, though put the wire size pipe on the lead, can not be fixed on the lead, time one is long, the wire size pipe that has will slide by the middle of guiding line, even comes off this method that present traditional passenger vehicle all is to use; For second method, though in a single day wire size is got on the line and is just eliminated never, but this process need carries out when producing, and there is serious discrepancy sometimes in cable manufacturer and wire harness manufacturing factory in communication process, and therefore this method does not also come into vogue at home.And these two kinds of methods can only know the wire size of every lead, as for the implication of wire size, can only obtain by searching related data for the beginner, not only time-consuming but also effort.

Compare with traditional passenger vehicle, hybrid power passenger car has that the car load wire harness is many, high-low pressure and deposit and intert mutually, the big characteristics of fax moving-wire bundle amount of correlated information.Therefore seeming in design wire harness and work progress is in a mess, and especially fax moving-wire Shu Yidan makes mistakes and tends to cause very serious consequence.

Summary of the invention

In order to solve the shortcoming that above-mentioned prior art exists, the method for quickly identifying and the system thereof that the purpose of this invention is to provide a kind of electrical transmission wires, it can make electrical transmission wires identification faster, more convenient, helps Fast Installation, maintenance fast, enhances productivity.

Technical scheme of the present invention is: a kind of method for quickly identifying of electrical transmission wires, and it may further comprise the steps:

A. fax moving-wire lead wire size is converted to 39 code system bar codes, bar code is corresponding one by one with the lead wire size;

B. with bar code printing on paster, and the paster that will be printed with bar code is attached to two ends of corresponding wire;

C. setting up with the bar code in computer is the electrical transmission wires wire size of index and the information database of technical conditions;

D. utilize the bar code on the bar code scanner scanning lead that connects on computers, computer promptly shows the wire size and the technical conditions of this lead, realizes the quick identification of electrical transmission wires.

The system for rapidly identifying of this electrical transmission wires comprises computer, bar code scanner, and the optical-electrical converter of bar code scanner connects amplification and rectification circuit and connects on computers by the decoding interface circuit.

The invention has the beneficial effects as follows: utilize this method and system thereof to improve the recognition speed of electrical transmission wires in process of production, help Fast Installation, maintenance fast, enhancing productivity, and then reduce production costs.

D. utilize the bar code on the bar code scanner scanning lead that connects on computers, computer promptly shows the wire size and the technical conditions of this lead, realizes the quick identification of electrical transmission wires.

The system for rapidly identifying of electrical transmission wires comprises computer, bar code scanner, and the optical-electrical converter of bar code scanner connects amplification and rectification circuit and connects on computers by the decoding interface circuit.

Receive informal voucher and the corresponding strong and weak different reflected light signal of secret note with bar code by the optical-electrical converter of bar code scanner, and convert the corresponding signal of telecommunication to, but, by optical-electrical converter output and bar bar code and the empty corresponding signal of telecommunication generally only about 10mV, can not directly use, thereby the amplifier of the big shaping circuit that the signal of telecommunication of optical-electrical converter output will be veered away earlier amplifies.The signal of telecommunication after the amplification remains an analog electrical signal, further the shaping circuit by amplification and rectification circuit becomes digital signal with analog signal conversion, and has avoided fault in the bar code and the stain signal that leads to errors.

The pulse digital signal of shaping circuit is translated into numeral, character information through the decoder of decoding interface circuit.Code system that it is initial by discerning, final character determines bar code symbol and scanning direction; Differentiate shaping and empty number by the number of measuring the pulse digit signal of telecommunication 0,1.Differentiate bar and empty width by measuring the lasting time of 0,1 signal.So just, the bar and empty number and the corresponding width and the used code system of the bar code symbol of reading have been obtained being debated, according to the pairing coding rule of code system, barcode scanner just can change bar symbol into corresponding digital, character information, give computer system by interface circuit and carry out data processing and management, just finished bar code and distinguished the overall process of reading.Can easily obtain the relevant information of arbitrary lead on computers, reach the purpose of quick identification.For more convenient work, computer can be used notebook computer.
