Abstract

The utility model provides a wire rod tester. The wire rod tester includes a test data transmitting module used for transmitting electric signals, a test data receiving module connected with the test data transmitting module through a wire rod and used for receiving the electric signals, a master control module connected with the test data transmitting module and the test data receiving module, and used for determining the conducting state of the wire rod according to the state of the electric signals received by the test data receiving module, and a test result indicating module connected with the master control module and used for indicating a test result of the wire rod. By adopting the utility model, the wire rod tester is composed of the test data transmitting module, the test data receiving module, the master control module and the test result indicating module; compared with a wire rod testing device manufactured by a professional equipment manufacturer, the wire rod tester has a low price and all functions; and the wire rod tester can test states of a wire rod, such as a conducting circuit, an open circuit or a short circuit, and can test different types of wire rods.

Description

A kind of wire rod test device

Technical field

The utility model relates to technical field of measurement and test, relates in particular to a kind of wire rod test device.

Background technology

Existingly with multimeter, detect wire rod method, inconvenient operation, efficiency is low, is difficult to meet the demand of producing in enormous quantities, can only detect the break-make of wire rod, can not detect the short circuit of wire rod; The wire rod checkout equipment that uses professional equipment manufacturer, the relative the utility model of cost is too high again.

Utility model content

Given this, be necessary to provide a kind of wire rod test device.

A wire rod test device, comprising:

Test data sending module, sends electric signal;

Test data receiver module, is connected by wire rod with described test data sending module, receives described electric signal;

Main control module, connects described test data sending module and test data receiver module, receives the conducting state of the situation judgement wire rod of described electric signal according to described test data receiver module;

Test result indicating module, is connected with described main control module, indication wire rod test result.

Preferably, also comprise wire rod type selecting module, select the type of test wire rod.

Preferably, described wire rod type comprises RJ11 telephone wire, US B line and RJ45 netting twine.

Preferably, described test result indicating module comprises LED light and hummer.

Preferably, described main control module is AT89S51 single-chip microcomputer.

Preferably, described electric signal is 0 or 1 level signal.

Adopt after the utility model, the wire rod test device that forms by test data sending module, test data receiver module, main control module and test result indicating module, the wire rod checkout equipment of comparing professional equipment manufacturer has cheap, multiple functional feature, can detect path, open circuit and the short circuit of wire rod, can detect dissimilar wire rod simultaneously.

Accompanying drawing explanation

The structural representation of the wire rod test device that Fig. 1 provides for the utility model;

The circuit diagram of the wire rod test device that Fig. 2 provides for the utility model.

Embodiment

In order to make relevant technical staff in the field understand better the technical solution of the utility model, accompanying drawing below in conjunction with the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.

Consult Fig. 1, Fig. 2, the utility model provides the wire rod test device of better embodiment, comprise test data sending module 10, test data receiver module 20, main control module 30, test result indicating module 40 and wire rod type selecting module 50, test data sending module 10 is connected by wire rod with test data receiver module 20.

Test data sending module 10, sends electric signal.Electric signal is 0 or 1 level signal.

Test data receiver module 20, is connected by wire rod with test data sending module 10, receives the electric signal being sent by test data sending module 10.

Main control module 30, connecting test data transmission blocks and test data receiver module, according to the conducting state of the situation judgement wire rod of data reception module 20 reception electric signal.The conducting state of wire rod comprises open circuit, path and short circuit.

Preferably, main control module is AT89S51 single-chip microcomputer, and this single-chip microcomputer stable performance is powerful, price material benefit.

Test result indicating module 40,, be connected indication wire rod test result with described main control module.

Preferably, test result indicating module 40 comprises LED light and hummer.By red green LED lamp is set, hummer is informed user test result.Consult Fig. 2, during LED9 green light, show that the red light power supply of LED1 to LED8 is normal.In test process, some blinking red lamps, show this cable open circuit; Some red light Chang Liang, show this cable short circuit; If all red lights do not glimmer or Chang Liang, show that this cable, by test, is path, LED10 green light Chang Liang, and hummer rings a sound; If any one blinking red lamp of LED1 to LED8 or Chang Liang, test is not passed through, LED11 red light Chang Liang, and hummer yowls.

Wire rod type selecting module 50, is connected with main control module 30, selects the type of test wire rod.Wire rod type comprises RJ11 telephone wire, USB line and RJ45 netting twine.

Concrete, RJ11 telephone wire is also divided into 2PIN and 4PIN, and RJ45 netting twine is divided into that RJ45_8PIN is straight-through, RJ45_8PIN intersects, RJ45_4PIN is straight-through and RJ45_4PIN intersects.Wire rod type selecting module 50 is selected the concrete model that need to test wire rod by DIP combined switch, specifically consult Fig. 2.

Below only expressed several embodiment of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
