As seen from the figure, a kind of generation method of low-frequency cable grouping electric performance test scheme mainly comprises the following steps:
Step (one) sets up form annexation data list as shown in Table 1, totally 6 row 10 row, first is classified as sequence number, second is classified as cable code name, 3rd is classified as top electric connector code name, 4th is classified as top electric connector specification, and the 5th is classified as terminal code name, and the 6th is classified as terminal electric connector specification.Often capable corresponding one group of annexation; Set up the transit cable list of record transit cable specification and quantity simultaneously;
Step (two), the value of current line variable arranging pending electric connector relation list are n, arrange current line n=1;
Step (three), set up one and be used for recording the specification of pending electric connector and the grouping of quantity, be grouped into sky;
The top electric connector specification of current line n and terminal electric connector specification in the connection relation list generated in step (four), read step ();
Top electric connector specification in step (four) and terminal electric connector specification also add in the grouping that step (three) sets up by step (five), therefore the data in current group are { " J14A-62TK ": 1, " DBMA44P ": 1 };
Record specification and the quantity of current various electric connector in step (six), grouping, and contrast the quantity of electric connector specification and quantity and same size transit cable in current group; In current group, the quantity of two kinds of electric connectors is all less than the quantity of same size transit cable; Therefore current behavior n=2 is set, reads the second row annexation.
When reading the second row annexation, the code name of top electric connector does not change, therefore top electric connector no longer adds in grouping, and terminator terminating junctor there occurs change, therefore the specification of terminator terminating junctor is added in grouping, the data of current group become { " J14A-62TK ": 1, " DBMA44P ": 2 }, again judge, find that integrated data is still less than transit cable quantity, therefore current line n=3 is set, reads the third line data.
When reading the third line annexation, we find, the code name of top electric connector there occurs change, therefore top electric connector is needed to add in grouping, terminator terminating junctor also there occurs change, therefore the specification of terminator terminating junctor is added in grouping, the data of current group become { " J14A-62TK ": 2, " DBMA44P ": 2, " DCMA37S ": 1 }, again judge, find that integrated data is still less than transit cable quantity, therefore current line n=4 is set, reads fourth line data.
According to identical treatment principle, during process fourth line data, packet count becomes { " J14A-62TK ": 2, " DBMA44P ": 2, " DCMA37S ": 1, " DCMA37P ": 1 }; Again judge, find that integrated data is still less than transit cable quantity, therefore current line n=5 is set, read fifth line data.
During process fifth line data, integrated data becomes { " J14A-62TK ": 3, " DBMA44P ": 2, " DCMA37S ": 1, " DCMA37P ": 1, " J14A-51TK ": 1 }, this is by the comparing with transit cable, and the quantity of J14A-62TK has exceeded the quantity of transit cable, and the grouping before therefore needing using process one's own profession exports as first group of data, therefore first group of integrated data is { " C201C-X5 ", " C601-X8 ", " C602-X8 ", " C201C-X6 ", " N01-X15 ", " N01-X16 " }.
Step (seven), exported grouping after, second grouping need be set up, and current line n=5 is set, again process fifth line data.
The generation of follow-up grouping and first process of dividing into groups similar, repeat no more.The grouping scheme finally generated is:
First grouping: { " C201C-X5 ", " C601-X8 ", " C602-X8 ", " C201C-X6 ", " N01-X15 ", " N01-X16 " }
Second grouping: { " C201C-X7 ", " V05A-X5 ", " C201C-X8 ", " N07A-X03 ", " N08A-X03 " }
3rd grouping: { " V01A-X6 ", " N07A-X03 " }
Owing to being that the grouping carried out as minimum packets unit by the electric connector a pair with annexation is attempted when generating testing scheme, it is hereby ensured the integrality of each annexation in grouping, again each connector divided into groups is gathered simultaneously, can draw with connectors all in cable to gather combing consistent, can illustrate that each electric connector is obtained for test, test coverage and to be comprehensively guaranteed.Like this, after reviewer performs often group test respectively by this grouping scheme, the complete test of all products is completed the most at last.
The content be not described in detail in instructions of the present invention belongs to the known technology of those skilled in the art.
