Description
Technical field
The present invention relates to a kind of autotest program generation method, relate in particular to a kind of spacecraft low-frequency cable electrical property autotest program generation method, belong to spacecraft low-frequency cable product field of automatic testing.
Background technology
Spacecraft low-frequency cable net is the visual plant of realizing the functions such as electric power conveying between each subsystem instrument and equipment of spacecraft or uphole equipment, command, message exchange, " blood vessel " and " neural network " in star, boat system, the quality of spacecraft low-frequency cable net quality is most important for the combination property of spacecraft, determining the success or failure of aerial mission, particularly, to manned task, be related to spacefarer's life.
Yet the electric performance test work of spacecraft low-frequency cable net product at present rests on the stage of test manually always, by two people or many people, coordinated, the information such as contrast drawing, connection table, core line are used the conventional tool pointwises such as megohmmeter and hummer to detect.Testing efficiency is low, speed is slow, working strength is large, easily make people tired, very easily cause undetected, false retrieval, also cannot obtain concrete measured value simultaneously, without actual observation record, manual detection is easily subject to the impact of personal mood in addition, and test mass is difficult to guarantee, cannot have met spacecraft develops task demand for development.Ge population unit, to Product Acceptance Review stage, general assembly and whole star test phase, all needs a large amount of low-frequency cable products to carry out electric performance test, and these work all mainly rely on manual completing, and workload is huge.
Development along with China's aerospace industry, during " 12 ", development and the test assignment of spacecraft low-frequency cable net product more will be doubled and redoubled, and continuing to adopt manual test mode to become affects the bottleneck that development task completes smoothly, must adopt automatic test means to address this problem.
Aviation at present, military project, automobile, the other industries such as locomotive generally adopt ripe ATE (automatic test equipment) to complete the test job of low-frequency cable product.But in aerospace system, though through repeatedly making great efforts, rarely has the case of ripe scheme or successful implementation and application.Tracing it to its cause, is mainly because existing equipment and scheme are difficult to meet feature and the test request of spacecraft cable system product.Testing apparatus on market and method of testing be generally only applicable in enormous quantities, on a small scale, simple in structure, the simple situation of annexation, and be difficult to adapt to the feature of space product and development task.By analysis, the difficulty of spacecraft cable system product application automatic test technology mainly contains these points:
(1) large, the complex structure of spacecraft cable scale, high to the Capability Requirement of equipment

(1) according to the design of various different-formats contact list file, generate the test contact table that XML file layout represents, the test of XML file layout is as follows with contact table, designs as shown in table 1 with contact table.
Table 1 design contact representation case
In this test, with in contact table, the annexation of a cable " W001 " has been described.Wherein having two electric connectors, is respectively " X01 " and " X02 ", and their specification is respectively " J36A-52TK " (electric connectors of rectangle 52 cores) and " J36A-62TJ " (electric connectors of rectangle 62 cores).Test with the concatenate rule described in contact table is: bracket represents short circuit, the contact outside top bracket and the contact short circuit in bracket, and the contact outside top bracket is corresponding one by one with the contact of terminal simultaneously, connects long line.
(2) generate electric connector list, generate electric connector library file, generate transit cable library file.
According to test, with contact table, extract electric connector to information, obtain electric connector list, and generate electric connector library file and transit cable library file according to electric connector list.Electric connector library file and transit cable library file are XML files, and XML is a kind of extend markup language, can be used for representing the complex data of tree structure.What read-write XML file was used is DOM technology, DOM(Document Object Model) be document dbject model, can control the data object in XML file.
Read electric connector list, the groundwork that generates electric connector library file and transit cable library file is that XML file is processed, and uses DOM technology to read or write DOM node according to the requirement of XML file layout.The electric connector library file generating is as follows:
The transit cable library file generating is as follows:
(3) generate test data file
With an example explanation, generate the concrete grammar of test data file below.
According to test, use contact table, the annexation in contact table can be converted to 20 groups of connection relational table one to one:
W001:
Link[1]:X01:14,X01:15
Link[2]:X01:14,X02:41
Link[3]:X01:16,X01:17
Link[4]:X01:16,X02:42
Link[5]:X01:18,X01:19
Link[6]:X01:18,X02:51
Link[7]:X01:20,X01:21
Link[8]:X01:20,X02:52
Link[9]:X01:22,X01:23
Link[10]:X01:22,X02:53
Link[11]:X01:24,X01:25
Link[12]:X01:24,X02:54
Link[13]:X01:11,X02:47
Link[14]:X01:12,X02:48

Link[19]:X01:5,X02:59
Link[20]:X01:6,X02:60
And then, can generate figure according to above-mentioned connection relational table, and generate test network table by graph traversal algorithm, this net list one to one annexation generates 14 net lists, the contact being interrelated is placed in same net list to (numeral in bracket is the nodes in net list) as follows:
W001:
Net[1](2):X01:1,X02:55
Net[2](2):X01:11,X02:47
Net[3](2):X01:12,X02:48
Net[4](3):X01:14,X01:15,X02:41
Net[5](3):X01:16,X01:17,X02:42
Net[6](3):X01:18,X01:19,X02:51
Net[7](2):X01:2,X02:56
Net[8](3):X01:20,X01:21,X02:52
Net[9](3):X01:22,X01:23,X02:53
Net[10](3):X01:24,X01:25,X02:54
Net[11](2):X01:3,X02:57
Net[12](2):X01:4,X02:58
Net[13](2):X01:5,X02:59
Net[14](2):X01:6,X02:60
Wherein network 1,2, and 3,7,11,12,13,14 only have two nodes, and remaining network respectively has three nodes.
According to knowing in this net list, each node of each net list inside has annexation, there is no annexation between each net list.Generate insulation meter, need according to net list, extract any one node (for convenience of processing, getting first node of each net list) in each net list, can generate first's insulation meter, the first's insulation meter having generated is as follows shown in column data:
