In the description of the invention, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear", The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outer " is based on accompanying drawing institutes The orientation or position relationship shown, is for only for ease of the description present invention and simplifies description, rather than indicate or imply signified dress Put or element there must be specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to present invention protection The limitation of scope.
Embodiments of the invention are described in detail below in conjunction with the accompanying drawings, Fig. 1 are referred to Fig. 2；
A kind of processor signal fault automatic positioning method of the present invention, wherein, SHARC position is passed behind failure SAHRC It is the biggest obstacle for carrying out accident analysis at letter to enter caused No. SHARC and LINK confusions, to solve this problem, we Failure is classified first：
The first situation：The LINK4 port communications of No. 1 SHARC LINK4 mouths and No. 0 SHARC in estori l plates go out Existing failure, because No. 1 SHARC is first SHARC, follow-up all SHARC loadings all must since No. 1 SHARC, so All SHARC below will be unable to proper communication, can all lack.Due to not detecting any SHARC, so being not present The displacement problem of No. SHARC and No. LINK.
Second of situation：All SHARC can proper communication, detect 63 SHARC, that is, without failure, institute So that the displacement problem of No. SHARC and No. LINK is also not present.
The third situation：The LINK5 port communications of No. 62 SHARC LINK4 mouths and No. 1 SHARC break down, No. 62 SHARC and follow-up No. 63 SHARC will missings.But because they are most latter two SHARC of whole link, so can only lack Most latter two SHARC, the position that follow-up connection SHARC is not had is progressive, will not cause the shifting of any No. SHARC and No. LINK Position.
4th kind of situation：The LINK0 mouths of No. 63 SHARC of last SHARC of link LINK4 mouths and No. 62 SHARC Communication is broken down, No. 63 SHARC missings, due to without any SHARC, follow-up connection SHARC position is not had below Put progressive, so the displacement of any No. SHARC and No. LINK will not be caused.
It is exactly No. 2 to the 61st that a kind of last situation, which is also most universal, most complicated, need most our situations of emphasis solution Any one SHARC LINK4 mouths communicate failure with higher level SHARC between number SHARC.It can cause follow-up same master A series of SHARC on link can not communicate, and produce missing, then the SHARC that can be found on other primary links progressive will be arrived Failure SHARC position, produces the confusion of No. SHARC and No. LINK displacement.This entanglement seems disorderly and unsystematic, but carefully studies Or it can find to have the company after the annexation and failure and missing SHARC before certain rule, failure SHARC Connect relation completely different.
SHARC before failure SHARC is not shifted in itself, if the SHARC correspondences before failure SHARC connect Connect be also failure SHARC before SHARC, due to not progressive displacement, then No. SHARC and LINK slogans are all kept not Become.If other failures of exactly failure SHARC and the related missing of the SHARC correspondence connections before failure SHARC SHARC, due to SHARC missings, will no longer be shown No. SHARC and LINK slogans.If SHARC pairs before failure SHARC That should connect is the SHARC after failure and missing SHARC, due to No. SHARC after failure and missing SHARC Displacement is progressive, causes its No. SHARC to change, and the quantity of change is equal to the SHARC sums of missing, but LINK slogans are kept not Become.
And the SHARC after failure and missing SHARC has occurred and that displacement in itself, original failure and missing are accounted for SHARC position, so No. SHARC with a line correspondence connection compares with LINK slogans, either No. SHARC and LINK mouthfuls Number may all change, and no rule can be followed.
A kind of processor signal fault automatic positioning method is obtained according to this five kinds of different characteristic rules of fault mode, is wrapped Include following steps:
1), initial data is converted and imported；
The text formatting that the testing result of APEX software dos windows is preserved into txt utilizes VBA as original data source (Visual Basic For Application) writes program and realizes the importing for being automatically performed detection initial data and conversion work Make.
The beginning analysis button of troubleshooting analysis software at programmable integrated process letter is clicked on, ejection imports text dialog box, Selection needs the data source imported, is imported.Data for the ease of after carry out com-parison and analysis, and we will be to original detection Data carry out certain automatic conversion processing, and we realize original detection automatically using troubleshooting analysis software at programmable integrated process letter The fractionation of data integer part and fractional part, is rearranged, and is finally deposited into 64 rows, the data Lead-In Area of 12 row.
2), using correct data area, data Lead-In Area and data compare area and carry out automatic data comparison operation and store Comparative result；
If the data of Lead-In Area are 0, annexation is lacked between illustrating SHARC herein, without comparing calculating.Such as Tab phenolphthaleinum It is not 0 to enter the data in area, and the data of Lead-In Area are subtracted with the corresponding data in correct data area, can draw correct testing result and Comparative result between No. SHARC of error detection result between LINK slogans, comparative result is stored in data and compares area；Its Middle algorithm is：
AA3=IF (O3=0,0, B3-O3), AA4=IF (O4=0,0, B4-O4) ... is by that analogy.
3) judged using four layers of IF function pairs accident analysis of nesting of form, ask for lacking SHARC quantity；
Failure is divided into five class situations by we, finds the index that several key points make a decision, the nested four layers of IF letters in the inside Number makes a decision, and to ask for lacking SHARC quantity, specific algorithm is：
AN3=IF (O4+P4+Q4+R4+S4+T4+U4+V4+W4+X4+Y4+Z4=0,63, IF (O66+P66+Q66+R66+ S66+T66+U66+V66+W66+X66+Y66+Z66>0,0, IF (Y4=0,2, IF (X65=5,1, MAX (AA4:AL4)))))
AN4=AN3
AN5=AN4
……
1st condition be：IF (O4+P4+Q4+R4+S4+T4+U4+V4+W4+X4+Y4+Z4=0,63, that is, the 1st SHARC failures, all SHARC below can be lacked, and the SHARC quantity of display missing is 63.
Second condition be：
IF(O66+P66+Q66+R66+S66+T66+U66+V66+W66+X66+Y66+Z66>0,0, represent to work as
No. 63 SHARC is present, and representing all SHARC can be detected, and missing SHARC numbers are 0,
Namely without failure.
3rd condition be IF (Y4=0,2, represent SHARC1 LINK5 mouths and SHARC62 LINK4 mouth connecting faults, Namely No. 62 SHARC are not found, then display result lacks 2.
4th condition be IF (X65=5,1, that is, No. 62 SHARC LINK4 and No. 1 SHARC LINK5 mouths it is normal In the case of connection, No. 62 SHARC are necessarily normal, but are unsatisfactory for first condition, and that must be just that lost No. 63 1 SHARC, it is 1 as a result to show missing SHARC numbers.
If these conditions are all unsatisfactory for, that is, lost between No. 1 and No. 62 SHARC, call maximizing function MAX(AA4:AL4), cause the characteristics of sequence number is progressive using lacking SHARC, obtain the maximum of the 4th row SHARC sequence number differences, The SHARC quantity that result of calculation is just missing from.
4) judgment value, is asked for；
Algorithm is：
AM4=IF (O4+P4+Q4+R4+S4+T4+U4+V4+W4+X4+Y4+Z4=0,0, IF (COUNTIF (AA4:AL4, AN3)+COUNTIF(AA4:AL4,0)=12,1,0))
AM5=IF (O5+P5+Q5+R5+S5+T5+U5+V5+W5+X5+Y5+Z5=0,0, IF (COUNTIF (AA5:AL5, AN4)+COUNTIF(AA5:AL5,0)=12,1,0))
……
By that analogy
If the data of a line of Lead-In Area are all 0, representative does not detect SHARC herein, then judgment value meter 0, without calculating.If the value comparative result for comparing area's a line be AN3 (AN3 for missing SHARC quantity) value either 0, illustrate that it has the feature of the SHARC before failure SHARC：No. SHARC and LINK slogans it is all constant, comparative result is 0；No. SHARC missing, comparative result is 0；LINK slogans are constant, simply corresponding No. SHARC unified displacement AN3 Position, comparative result is AN3.Meet conditions above judgment value meter 1, otherwise count 0.Judgment value for 1 SHARC be failure SHARC it Preceding SHARC, the SHARC that judgment value is 0 are the SHARC after failure and missing SHARC, and judgment value is for calculating failure later No. SHARC is prepared.
5) failure SHARC, is calculated
AQ3=IF (O4+P4+Q4+R4+S4+T4+U4+V4+W4+X4+Y4+Z4=0,1, IF (O66+P66+Q66+R66+ S66+T66+U66+V66+W66+X66+Y66+Z66>0,0, IF (Y4=0,62, IF (X65=5,63, SUM (AM3:AM66)+ 1))))
1st conditional function：
IF (O4+P4+Q4+R4+S4+T4+U4+V4+W4+X4+Y4+Z4=0,1,
The 1st SHARC failure is represented, display failure SHARC is 1.
2nd conditional function：
IF(O66+P66+Q66+R66+S66+T66+U66+V66+W66+X66+Y66+Z66>0,0,
Represent all SHARC to be all detected, without failure.It is 0 to show failure SHARC.
3rd conditional function：
IF (Y4=0,62,
SHARC1 LINK5 mouths and SHARC62 LINK4 mouth connecting faults are represented, that is, No. 62 SHARC are not detected Arrive, then failure SHARC is 62.
4th conditional function：
IF (X65=5,63, SUM (AM3:AM66)+1),
Represent No. 62 SHARC LINK4 and No. 1 SHARC LINK5 mouths it is normal be connected in the case of, No. 62 SHARC are certain Normally, then failure SHARC is 63.
If above-mentioned situation is not complyed with, that SUM (AM3 that just sum:AM66)+1, judgment value just now is summed.Due to The judgment value of row before failure SHARC is 1, and the judgment value of the row after failure and missing SHARC is 0, so handle is sentenced The SHARC1 that disconnected value adds up plus intrinsic ESTOIL plates, its value is exactly failure SHARC position number.
Failure SHARC is would indicate that in software window, is easy to maintenance and debugging personnel to check., can after the completion of accident analysis Proceed next analysis, can also press the button that quits a program and exit.
A kind of processor signal fault automatic positioning method of the present invention, fast automatic can be accurately positioned airborne radar processing The trouble point of machine signal processing, can be greatly enhanced troubleshooting efficiency, be greatly enhanced the fault location degree of accuracy, due to behaviour Make easy, fault location is very accurate, be not only applicable to general processor debugging troubleshooting personnel and carry out fault location at letter, may be used also With other librarian uses to not any processor technical foundation, outfield ground crew can also be supplied to be used for processor Malfunction elimination.
It is last it is to be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations.To the greatest extent The present invention is described in detail with reference to the foregoing embodiments for pipe, it will be understood by those within the art that：It is still Technical scheme described in foregoing embodiments can be modified, or which part technical characteristic is equally replaced Change；And these modifications or replacement, the essence of appropriate technical solution is departed from the essence of various embodiments of the present invention technical scheme God and scope.
