It needs to carry out malfunction elimination to serial line interface harness before connecting one to one.
The present invention is formal for these reasons, provides a kind of serial line interface harness failure detector.
With reference to figure 1, Fig. 1 provides one embodiment of the invention, in the present embodiment, serial 10 failure detector of harness
Including a female 30, female 30 is correspondingly arranged with serial line interface male connector 20, is provided with pin in female 30, the quantity of pin and
The quantity of harness 10 is identical in male connector 20, after female 30 and the docking of male connector 20, the harness in pin and male connector 20 in female 30
10 connect one to one.
Detection circuit 40 is led on pin, is connected after different detection circuits 40 are parallel with one another with a test point 60.
Display element is provided in detection circuit 40, it, can be straight by the state of display element after detection circuit 40 is connected
See reflect detection circuit 40 there are the problem of, then reflect failure problems existing for detected harness 10.Display element
Type can be acoustical generator or LED light 50.Using LED light 50 in the present embodiment, LED light 50 is simple in structure, cost
It is low, while display effect is good, can preferably reflect the current failure problems of harness 10.
Further, in order to protect the safety of LED light 50 in detection process, the present embodiment is also set up in detection circuit 40
One resistance 70, resistance 70 are connected with LED light 50, for preventing electric current is excessive from burning out LED light 50.
The present invention also provides a kind of serial line interface harness fault detection methods, comprise the following steps：
S1, to harness in serial line interface male connector successively into line label, be respectively a1, a2 ... an；
S2, by the female of serial line interface harness failure detector and the male connector pair of serial line interface described in claim 4
It connects, and marks the LED light in detection circuit as b1, b2 ... bn, wherein, a1 connections corresponding with b1, a2 is connected with b2, successively class
It pushes away, an is connected with bn；
S3, the connecting pin of harness a1 is inserted into test point, turns on detection circuit b1, if only b1 is lighted, judge
Harness a1 fault-frees if b1 does not work and other LED light do not work yet, judge harness a1 open circuits, if b1 does not work but other lamp bm are bright
It rises, then judges harness a1 misconnection position, if a1 is bright and other lamp bm are also bright, judge harness a1 short circuits；
S4, fault detect is carried out to harness a2 to harness an according to the detecting step of harness a1 successively.
The DB25 serial line interfaces (hereinafter referred to as DB25) used below using in flue gas analyzer are situated between in detail as example
Continue the detection process of the present embodiment：
25 harness of DB25 are marked successively from top to down first, are denoted as 1,2 ... No. 25 harness respectively, choose number of pins
The female for 25 is measured, is drawn on each pin of female and is connected with detection circuit, string after 25 detection circuits are parallel with one another
It is connected on a test point, is powered using 24V power supplys to 25 detection circuits, wherein, the display element in detection circuit
Using LED light, LED light is corresponding with the harness on DB25 to be respectively labeled as 1,2 ... 25 signal lamps.It is specific corresponding to mode, Line 1
Beam corresponds to No. 1 LED light, and No. 2 harness correspond to No. 2 LED light, and so on.
Female and male connector are docked, harness is made to be connected with corresponding detection circuit, starts to carry out event to 25 harness successively
Barrier investigation detection.In order to make the process of detection more orderly, in this example, sequence detection is up to No. 25 lines since Line 1 beam
Beam detection is completed.The connecting pin of Line 1 beam is inserted into test point, connects detection circuit, 1 to No. 25 LED light of observation
Display situation, and the situation of Line 1 beam is judged according to the display situation of 1 to No. 25 LED light.
Specific deterministic process is as follows：
If the 1, having in 1 to No. 25 LED light and only 1 signal lamp being bright, illustrate that Line 1 beam is normally connected with detection circuit, No. 1
There is no failure.
If the 2,1 signal lamp does not work in 1 to No. 25 LED light and other LED light do not work yet, illustrate Line 1 Shu Wufa and inspection
Slowdown monitoring circuit connects, and Line 1 beam has the problem of open circuit, general such case occur it is contemplated that property is judged as that harness is being squeezed into
During male connector, harness, it is necessary to be driven into male connector by loose contact from newly.
If the 3,1 signal lamp does not work but there are other LED light such as 3 signal lamps bright in 1 to No. 25 LED light, illustrate Line 1 Shu Lian
Led to the detection circuit where 3 signal lamps, due to the detection circuit interface where 3 signal lamps be it is unique, can judge mark line accordingly
Marked erroneous during beam, it is wrong that No. 3 harness are labeled as Line 1 beam, it is necessary to which harness is marked again.
The 4th, if not only 1 signal lamp is bright in 1 to No. 25 LED light and has other LED light such as 2 signal lamps while 1 signal lamp is bright
Also it is bright, then illustrate that Line 1 beam is not only connected with the detection circuit where 1 signal lamp, while also connect with the detection circuit where 2 signal lamps
Logical, i.e. 1 harness short cut with each other between resulting in two detection circuits.
Line 1 Shu Jinhang fault detects are investigated according to above-mentioned decision principle, if Line 1 beam has corresponding failure to ask
Topic then according to failure problems solve until Line 1 beam testing result is normal.After the completion of the detection of Line 1 beam, by same side
Method carries out malfunction elimination detection to remaining harness successively.
Specific embodiment described herein is only to spirit explanation for example of the invention.Technology belonging to the present invention is led
The technical staff in domain can do various modifications or additions to described specific embodiment or replace in a similar way
Generation, but without departing from spirit of the invention or beyond the scope of the appended claims.
