In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, not
For limiting the present invention.
The automatic identification equipment of the aviation socket signal wire numbering of the embodiment of the present invention, as shown in figure 1, including microprocessor
Device, and the bus extension unit and wireline inspection unit being connected with the microprocessor；
The bus extension unit includes multiple aviation socket/heads, be tested aviation plug/seat by the plurality of aviation socket/
Head is connected with the bus extension unit；
Tested aviation socket/head is also connected by pull-switch with wireline inspection unit；
The device also includes keyboard；
The model or cored wire number of aviation socket/head are tested by input through keyboard, microprocessor sends inspection signal simultaneously
The signal wire for identifying tested aviation socket/head according to the feedback signal of tested aviation socket/head is numbered.
The device also includes display or phonetic synthesis report unit, and microprocessor identifies tested aviation socket/head
Signal wire numbering after, show that the signal wire is numbered by display, or the signal played by phonetic synthesis report unit
Line is numbered.
In the embodiment of the present invention, the bus extension unit includes the multiport decoder electricity that PLD is realized
Road.
Further, in one embodiment of the present of invention, as shown in figure 3, the wireline inspection unit includes patchboard 31,
The cored wire of tested aviation socket/head is placed in the wiring card.Patchboard can be conductive, can be a part for pull-switch
(b)。
The first dielectric support bar 36 is fixed in the lower section of patchboard 31, and the bottom of the first insulating support rod 36 is provided with the first metal
Shell fragment 33, the lower section of the patchboard 31 are additionally provided with the second dielectric support bar 35, and the top of the second dielectric support bar 35 is provided with the
Two metal clips 34, the lower section of patchboard 31 are additionally provided with spring 32, one end and the bottom of patchboard 31 or first of the spring 32
Dielectric support bar 36 is connected, and the other end is connected with the second dielectric support bar 35；
The bottom of first metal clips 33, the second metal clips 34 and spring 32 passes through wire and wireline inspection unit
Pull-switch connection；The pull-switch includes four signal wires a, b, c and d.Pull-switch is tested the cored wire of aviation plug/seat
When being placed on patchboard, spring 32 is compressed, and the first metal clips 33 and the second metal clips 34 contact.
Input through keyboard is detected the model (or cored wire number M) of air plug, when the cored wire for being detected air plug is connected to pull-switch
When, the signal wire b and d of pull-switch are connected, simultaneously because pressure makes the signal wire a of pull-switch be connected with c, microprocessor B
Port is obtained from low level to high level, and triggering microprocessor starts to detect, and starts timer internal, and timer often reaches one
Secondary, internal accumulator accumulates once, and the value of the accumulator is transferred to aviation socket extension system, aviation socket extension internal system
The value of accumulator is entered into row decoding, it is low level to make corresponding cored wire numbering signal wire, and the low level signal passes through tested air plug,
Feed back to microprocessor port A.When port, A detects low level, microprocessor stops counting, the value conduct of memory accumulator
Cored wire is numbered, while the liquid crystal display numbering, and passes through the numbering that phonetic synthesis unit reports cored wire.
When the cored wire of tested air plug leaves pull-switch, microprocessor resets internal accumulator, while counts cored wire volume
Number, judge whether tested air plug cored wire detects and finish.If not detected, voice prompt operation person continues operation detection；If
Detection finishes, then voice broadcast detection finishes.
In detection is carried out, if the value of microprocessor internal accumulator is more than the cored wire sum of tested air plug, still without inspection
Feedback low level signal is measured, then voice message " cored wire is opened a way, and please be checked ".
In detection is carried out, if the cored wire numbering for tested air plug occur is identical with cored wire record number above after testing
When, then voice message " cored wire and the short circuit of * * pins, please check ".
Because the port number of microprocessor is limited, the numerical value of the accumulator of microprocessor internal is exported to port, warp
Bus extension is crossed, obtains the different corresponding decoding line of numerical value, therefore the maximum aviation socket cored wire number supported reaches in theory
216(using 16 bit accumulators).By taking 8 bit accumulators as an example, the air plug detection of 256 cores is supported, specifically available VHDL is retouched
State, realized using PLD.
The automatic identifying method of aviation socket of embodiment of the present invention signal wire numbering, as shown in Fig. 2 comprising the following steps：
Processor is started working, and waits embeded core line number mesh, after predetermined cored wire number is inputted, can call the code of storage
Change the internal structure of the PLD of bus extension；It can start to detect work by voice message after the completion of detection.
When operator does not operate, pull-switch is in vacant, and signal wire a, c and b, d open a way, microprocessor port
A is high level, and port B is low level.
When the cored wire of tested air plug is placed on patchboard by operator, due to Action of Gravity Field compression spring 32, make two bullets
Piece contacts, and forms path.Signal wire a is connected with c, and signal wire b connects with d, and microprocessor port B is changed into high electricity from low level
It is flat, start internal counter and count, the value of counter is exported to bus extension unit, decoded by bus extension unit, is made pair
The cored wire that should be exported in counter is low level, and other outputs are high level.
If circuit fault-free, be detected air plug cored wire, always have in counting process of the counter from 1 to M one it is right
The cored wire that the numerical value answered makes currently to be detected is in low level, so that port A is low level, when port A is low level, counts
Device stops counting, and microprocessor stores the numbering, and display shows numbering of the value as the cored wire of the counter, and by depositing
The numbering of the voice of storage and numbering synthesis voice report current detection cored wire, unison counter are reset, and prompt next cored wire inspection
Survey.
If counter exports, port A is high level, and the value for illustrating nonce counter is not to be detected cored wire
Numbering, counter continue to count, and until making port A be low level, record the numbering.
In detection process, the cored wire numbering detected every time needs to judge uniqueness, if the numbering with above detecting storage
There is repetition, illustrate that cored wire has short circuit phenomenon, prompt to check failure；
If in detection process, if the value of counter is more than predetermined cored wire number M, still can't detect port A is
Low level, then the cored wire of current detection is judged for open-circuit condition, prompt to check.
In summary, the present invention sends inspection signal by microprocessor, realizes the automatic of aviation socket signal wire numbering
Identification, while can be detected with welding quality.The present invention is realized using general-purpose device, and low cost can be achieved；In addition originally
The recognition methods adaptability of invention is stronger, by controlling PLD, changes its structure, is adapted to different cored wire numbers
Air plug detects, and the air plug for being also larger in number suitable following cored wire detects.
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
