The utility model formally for these reasons, provides a kind of serial line interface harness failure detector.
With reference to figure 1, Fig. 1 provides an embodiment of the utility model, in the present embodiment, 10 fault detect of serial harness
Device includes a female 30, and female 30 is correspondingly arranged with serial line interface male connector 20, and pin, the number of pin are provided in female 30
Amount is identical with the quantity of harness 10 in male connector 20, after female 30 and the docking of male connector 20, in the pin and male connector 20 in female 30
Harness 10 connects one to one.
Detection circuit 40 is led on pin, is connected with a test point 60 after different detection circuits 40 are parallel with one another.
Display element is provided in detection circuit 40 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, can also be LED light 50.LED light 50 is used in the present embodiment, LED light 50 is simple in structure, at
This 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 to be 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 utility model additionally provides a kind of serial line interface harness fault detection method, includes the following steps：
S1, to harness in serial line interface male connector successively into line label, respectively a1, a2 ... an；
S2, the female of serial line interface harness failure detector is docked with the male connector of serial line interface, and marks detection electricity
The LED light of road is b1, b2 ... bn, wherein a1 connections corresponding with b1, a2 are connected to b2, and so on, an is connected to bn；
S3, the connecting pin of harness a1 is inserted into test point, so that detection circuit b1 is connected, if only b1 is lighted, judges
Harness a1 fault-frees judge harness a1 open circuits, if b1 does not work but other lamp bm are bright if b1 does not work and other LED lamps do not work yet
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 pin
Quantity is 25 females, is drawn on each pin of female and is connected with detection circuit, after 25 detection circuits are parallel with one another
It is serially connected on a test point, is powered to 25 detection circuits using 24V power supplys, wherein the display member in detection circuit
Part uses LED light, and LED light is corresponding with the harness on DB25 to be respectively labeled as 1,2 ... 25 signal lamps.It is No. 1 specific corresponding to mode
Harness 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 to corresponding detection circuit, starts to carry out event to 25 harness successively
Barrier investigation detection.In order to keep 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, detection circuit is made to be connected to, observes 1 to No. 25 LED light
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 1, having in 1 to No. 25 LED light and only 1 signal lamp being bright, illustrate that Line 1 beam is normally connected to detection circuit, No. 1
There is no failure.
If 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 is connected to, and Line 1 beam has open circuit, general such case occur it is contemplated that property is judged as that harness is being squeezed into
When male connector, poor contact needs that harness is driven into male connector from newly.
If 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 when beam, it is wrong that No. 3 harness are labeled as Line 1 beam, it needs that harness is marked again.
If 4, 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 bright, then illustrate that Line 1 beam is not only connected to the detection circuit where 1 signal lamp, while also connecting 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 problems,
Then according to failure problems solve until Line 1 beam testing result is normal.After the completion of the detection of Line 1 beam, in the same way
Malfunction elimination detection is carried out to remaining harness successively.
