Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The automatic identification equipment of the aviation socket signal wire numbering of the utility model embodiment, as shown in Figure 1, comprises microprocessor, and the bus extension unit be all connected with this microprocessor and wireline inspection unit;
This bus extension unit comprises multiple aviation socket/head, and tested aviation plug/seat is connected with described bus extension unit by the plurality of aviation socket/head;
Tested aviation socket/head is also connected with wireline inspection unit by pull-switch;
This device also comprises keyboard;
By model or the heart yearn number of the tested aviation socket/head of input through keyboard, microprocessor sends patrols and examines signal and numbers according to the signal wire of the tested aviation socket/head of the feedback signal identification of tested aviation socket/head.
This device also comprises display or phonetic synthesis report unit, and microprocessor shows this signal wire numbering by display after identifying the signal wire numbering of tested aviation socket/head, or plays this signal wire numbering by phonetic synthesis report unit.
In the utility model embodiment, described bus extension unit comprises the multiport decoder circuit that programmable logic device (PLD) realizes.
Further, in an embodiment of the present utility model, as shown in Figure 3, described wireline inspection unit comprises patching panel 31, and the heart yearn of tested aviation socket/head is placed in this wiring card.Patching panel can be conduction, can be a part (b) for pull-switch.
The first dielectric support bar 36 is fixed below patching panel 31, the first metal clips 33 is provided with bottom this first insulating support rod 36, the second dielectric support bar 35 is also provided with below this patching panel 31, this the second dielectric support bar 35 top is provided with the second metal clips 34, spring 32 is also provided with below this patching panel 31, one end of this spring 32 with bottom patching panel 31 or the first dielectric support bar 36 be connected, the other end is connected with the second dielectric support bar 35;
The bottom of the first metal clips 33, second metal clips 34 and spring 32 is all connected by the pull-switch of wire with wireline inspection unit; This pull-switch comprises four signal wires a, b, c and d.When the heart yearn of the tested aviation plug/seat of pull-switch is placed on patching panel, spring 32 is compressed, and the first metal clips 33 contacts with the second metal clips 34.
Input through keyboard is detected the model (or heart yearn number M) of air plug, when the heart yearn of detected air plug receives pull-switch, signal wire b and the d of pull-switch connects, simultaneously because pressure makes signal wire a with c of pull-switch be connected, microprocessor B port obtains from low level to high level, triggers microprocessor starts to detect, start timer internal, timer often arrives once, inner totalizer accumulates once, the value of this totalizer is transferred to aviation socket expanding system, the value of totalizer is carried out decoding by aviation socket expanding system inside, corresponding heart yearn numbering signal wire is made to be low level, this low level signal is through tested air plug, feed back to microprocessor port A.When port A detects low level, microprocessor stops counting, and the value of memory accumulator is numbered as heart yearn, this numbering of liquid crystal display simultaneously, and is reported the numbering of heart yearn by phonetic synthesis unit.
When the heart yearn of tested air plug leaves pull-switch, inner totalizer resets by microprocessor, adds up heart yearn numbering simultaneously, judges whether tested air plug heart yearn detects complete.If do not detected, then voice prompt operation person has continued operation detection; If detect complete, then voice broadcast detects complete.
In detection is carried out, if the value of microprocessor internal totalizer is greater than the heart yearn sum of tested air plug, still feedback low level signal do not detected, then voice message " this heart yearn is opened a way, and please check ".
In detection is carried out, if occur, the heart yearn numbering of tested air plug is with when heart yearn record number is after testing identical above, then voice message " this heart yearn and the short circuit of * * pin, please check ".
Because the port number of microprocessor is limited, export the numerical value of the totalizer of microprocessor internal to port, through bus extension, obtain the corresponding decoding line that numerical value is different, the aviation socket heart yearn number of therefore maximum support in theory reaches 2
16(16 bit accumulators can be utilized).For 8 bit accumulators, support that the air plug of 256 cores detects, concrete available VHDL is described, and adopts programmable logic device (PLD) to realize.
The automatic identifying method of the utility model embodiment aviation socket signal wire numbering, as shown in Figure 2, comprises the following steps:
Processor is started working, and waits for preset heart yearn number, when after the heart yearn number that input is predetermined, can call the inner structure of the programmable logic device (PLD) of the code revision bus extension of storage; Testing is started by voice message after detection completes.
When operator does not operate, pull-switch is in vacant, and signal wire a, c and b, d all open a way, and microprocessor port A is high level, and port B is low level.
When the heart yearn of tested air plug is placed on patching panel by operator, due to Action of Gravity Field Compress Spring 32, make two shell fragment contacts, form path.Signal wire a and c connects, signal wire b with d is connected, microprocessor port B becomes high level from low level, start internal counter counting, the value of counter exports bus extension unit to, by bus extension cell decode, make the heart yearn corresponding to counter output be low level, other exports as high level.
If circuit non-fault, the then heart yearn of detected air plug, the counting process of counter from 1 to M, always there is a corresponding numerical value to make current detected heart yearn be in low level, thus make port A be low level, when port A is low level, counter stops counting, microprocessor stores this numbering, display shows the numbering of value as this heart yearn of this counter, and the numbering of current detection heart yearn is reported by voice and the numbering synthetic speech stored, unison counter resets, and points out next root heart yearn to detect.
If counter exports, port A is high level, illustrates that the value of nonce counter is not the numbering of detected heart yearn, and counter continues counting, until make port A be low level, records this numbering.
In testing process, each heart yearn numbering detected needs to judge uniqueness, if having repetition with the numbering detecting storage above, illustrate that heart yearn exists short circuit phenomenon, prompting checks fault;
If in testing process, if the value of counter is greater than predetermined heart yearn number M, still can't detect port A is low level, then judge that the heart yearn of current detection is open-circuit condition, and prompting checks.
In sum, the utility model the utility model is by conductive patching panel, as long as make the heart yearn of tested aviation socket/head be placed in this wiring card just can connect detection, convenient and swift.The air plug being applicable to different heart yearn number by bus extension unit is detected, and also detected by air plug larger for applicable following heart yearn number, adaptability is stronger.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to the utility model claims.
