Abstract
The utility model discloses a line testing instrument, wherein the line testing instrument comprises a singlechip which is connected with a power supply and is also connected with a patching board, an indicator light is arranged on the patching board, and the singlechip is also connected with a reset circuit. The line testing instrument can conveniently detect a tested connection line by the structure, and has high efficiency and low cost.
Description
[technical field]
The utility model relates to a kind of tester, relates in particular to a kind of tester that is used to check connecting line.
[background technology]
The mass-produced connecting line of our company is as netting twine, winding displacement, data line, cable etc.; Because of detecting reason such as inconvenience, part excludes sensing range, and part detects with multimeter, and efficient is low, easily makes mistakes, detect to connect 5V Switching Power Supply, resistance and LED lamp, if the connecting line short circuit, then fragile Switching Power Supply.And the problem because of line causes burning integrated circuit board in the actual production, happens occasionally.Produce and improve and check, this tester of special work for convenient.
[summary of the invention]
The purpose of this utility model is to provide a kind of can detect tested connecting line easily, and efficient height, tester that cost is low.
The technical scheme that the utility model adopted is: a kind of tester, and wherein, described tester comprises single-chip microcomputer, this single-chip microcomputer is connected with a power supply, described single-chip microcomputer also is connected with a card extender, and the dress pilot lamp is arranged on this card extender, and described single-chip microcomputer also links to each other with a reset circuit.
The technique effect that the utility model reached is: can detect tested connecting line easily, and the efficient height, cost is low.
[description of drawings]
The utility model will be further described in conjunction with embodiment with reference to the accompanying drawings.
Fig. 1 is the principle process synoptic diagram of the utility model tester.
[embodiment]
By describing technology contents of the present utility model, structural attitude in detail, being reached purpose and effect, below in conjunction with embodiment and cooperate graphic detailed description the in detail.
See also Fig. 1, the utility model detector comprises single-chip microcomputer, and this single-chip microcomputer is connected with a power supply, and described single-chip microcomputer also is connected with a card extender, and the dress pilot lamp is arranged on this card extender, and described single-chip microcomputer also links to each other with a reset circuit.
The single-chip microcomputer of the utility model detector adopts the ATMEGA8515 single-chip microcomputer.Power supply is input as 5 volts, can adopt and directly connect 5 volts Switching Power Supply, perhaps also can adopt the battery that connects 9 volts to be converted to 5 volts through converter.Employing connects 9 volts battery, carries more convenient.
Bright, the continuing and interval time of going out of Single-chip Controlling pilot lamp, thus judge tested connecting line whether conducting or short circuit.Can reset in the testing process, restart to detect.
When the conducting of detected netting twine connecting line, instigate lamp just bright when then detecting this on corresponding leg, general rule does not work; In the time of adjacent two the leg short circuits of detected netting twine, then when detecting these two leg wherein during any one leg, the pilot lamp on these two leg is all bright.Testing process is leg inspection one by one successively.
When the number of the leg of detected netting twine was above greater than 9, then pilot lamp, even number bright with odd number went out, and even number is bright, odd number goes out, and is bright entirely, go out entirely four successively delay operation whether detect winding displacement be good, cycle detection.
Leave the program download interface on the single-chip microcomputer.The routine interface that leaves on this single-chip microcomputer not only can make the replacing program simple and convenient, and can connect different card extenders so that detect different connection terminals and different connecting lines.
In sum, the utility model tester can detect tested connecting line easily by said structure, and the efficient height, and cost is low.
