Description

Automatic wire

Technical field

The utility model relates to a kind of detecting instrument, be particularly related to a kind of automatic wire, this instrument can judge automatically whether cable connects correct, can detect electrical control or the communication line line made in fields such as telecommunications, electric power, controls exactly and whether carry out correct connection according to the order of connection of prior agreement, can set to determine connection mode by keyboard connection mode, after detection, can show testing result.

Background technology

In rail electric locomotive and passenger vehicle production run, because the raising of automaticity, signal transmission and electrical control connection cable are more and more, brought certain degree of difficulty when giving operator's wiring, the phenomenon that occurs wrong sometimes, in case the wrong cable may be accidents caused, causes great economic loss and social influence.And many cables need a large amount of time by hand inspection after connecting, and are not only quite loaded down with trivial details but also exist the inspection wrong possibility of not coming out.At home, have two of can detect every lead correspondence in the polycore cable to lift one's head the correcting line machine of function at present, but it have only ten and two kinds of specifications of ten six roots of sensation, do not have special-purpose plug connector, only press from both sides single connection lead, show break-make, do not have memory function with led lighting with the huge legendary turtle fish.

Summary of the invention

The purpose of this utility model is in order to solve the whether problem of the poor accuracy of wasting time and energy and detecting that exists of wrong process of the electric cable of manual detection, and existing wire device problem poor for applicability, but and provide that a kind of one-time detection cable is many, detection efficiency is high, and the wire of store information.

The utility model is by detecting transmitter and detecting receiver two parts and form, wherein, detecting transmitter is made up of emitting antenna, single-chip microcomputer, serial-parallel conversion circuit, multichannel connector, display and detection button, emitting antenna, serial-parallel conversion circuit, display and detection button are electrically connected with single-chip microcomputer, and the multichannel connector is electrically connected with serial-parallel conversion circuit; Detect receiver and be made up of receiving antenna, single-chip microcomputer, serial-parallel conversion circuit and multichannel connector, receiving antenna, serial-parallel conversion circuit are electrically connected with single-chip microcomputer, and the multichannel connector is electrically connected with serial-parallel conversion circuit; The model of two single-chip microcomputers is 89C51.

The principle of work of detection of the present utility model is: detect transmitter and mainly play the control emitting antenna and send signal with reception and judge that tested cable is connected the function of correctness and demonstration, detect receiver and mainly play the signal that receives the transmission of detection transmitter by receiving antenna, and it is sent to the effect of tested cable by the multichannel connector.Its course of work is: two multichannel connectors that at first will detect transmitter and detection receiver are received respectively on the joint or plug connector of cable to be measured, press the detection button, can detect automatically, and testing result can be shown on the liquid crystal display simultaneously.

The concrete step that detects is:

(1), at first press the detection button that detects transmitter, determine to begin to detect, outwards send radio signal by the Single-chip Controlling communicating circuit by emitting antenna, notice detects receiver;

(2), the receiving antenna that detects receiver receives and detects after the signal that transmitter sends, and through Single-chip Controlling signal outputed to serial-parallel conversion circuit, converts serial signal the signal of multidiameter delay to, sends to the multichannel connector; This signal will be delivered to the multichannel connector that detects transmitter by tested cable;

(3), detect transmitter after sending radio signal, begin to receive the signal that passes over by tested cable from the multichannel connector, after serial-parallel conversion circuit and string conversion, enter single-chip microcomputer, whether single-chip microcomputer compares the signal that receives and the signal of transmission then, correct to judge that tested cable connects.

(4) under the control of single-chip microcomputer, test result is shown on the LCD.

The beneficial effects of the utility model are: can replace manually the cable after connecting being detected, improved production efficiency greatly, and increased the reliability of testing result greatly, when the utility model is mainly used in rail vehicle manufacture process and semi-finished product inspection thereof cable is connected the detection of correctness, also can be applicable to the field that has many cables to connect when other are manufactured and need the school line simultaneously.
