Description
Technical field
The utility model belongs to field of automatic testing, especially relates to a kind of servo controller flexible automatic test system.
Background technology
The development experience of Auto-Test System is from tailored version to universal evolution process.Special Automatic test (DTS) has the advantages such as compact conformation, testing efficiency be high, easy to use, but Special Automatic test macro due to test resource configuration with strong points, interface between unit under test, between computing machine and testing tool and between testing tool does not have standardization, therefore the adaptability of system is not strong, test resource cannot be shared between multiple test assignment, be difficult to realize interoperability between different test macros, somewhat expensive large for complicated testing apparatus development work amount.
General purpose automatic test system (GATS) adopts open commercial criterion and industrial standard, reduces exploitation and the upgrade cost of test macro soft and hardware; There are the software systems (as LabVIEW) based on virtual instrument technique simultaneously, thus by software engineering extend testing function.But desirable universal test system cannot realize, the universal test system in reality is often or for the tested equipment of a certain class.Present most of universal test system generally adopts the card case structure based on VXI, PXI, gpib bus, and usual volume is all huger, working service inconvenience, very flexible; And due to certain versatility and parameters distribution face will be met, cause on the one hand that system instrument device category is numerous, complex structure, expensive, cause a large amount of functional redundancies on the other hand.
Current test macro has the following disadvantages: tailored version test macro has very strong specific aim to test resource configuration, and system development workload is large, cost is high, adaptability is not strong, is difficult to realize interoperability between different test macros.Universal test macro is owing to will meet certain versatility and parameters distribution face, cause test macro instrument and equipment huge number, bulky, complex structure, very flexible on the one hand, there is redundancy between each test resource of system on the other hand, add volume and the power consumption of test macro.
For being of limited application of existing Auto-Test System, development and maintenance cost is high, lack interoperability between system, testing and diagnosing new technology is difficult to incorporate many deficiencies such as existed system, Auto-Test System executive board of U.S. Department of Defense (DoDATSEAO) convenes the Army, Navy and Air Force, called after developed jointly by marine corps and industrial sector " NxTest ', Next Generation Automatic Test System.The main target of Next Generation Automatic Test System comprises:
L () significantly reduces maintenance and the cost of use of Auto-Test System;
(2) by improving the interoperability of test macro, final user being obtained and tests dirigibility to greatest extent;
(3) improve the dirigibility of test system configurations, meet different test subscriber's needs;
(4) injectability of Auto-Test System new technology is improved;
(5) development of push to test software development environment;
As can be seen here, the dirigibility of Next Generation Automatic Test System to test macro is had higher requirement, and namely test macro should have corresponding applicability and dirigibility, to meet the needs of fast-changing different testing requirement.Also should have extendability simultaneously, to improve test macro in ability be included to new technology.Auto-Test System based on flexible test technique construction can solve the problem present situation such as complex structure, bulky, very flexible, extendability are poor, scaling difficulty that existing test macro exists well, meets the objectives requirement of Next Generation Automatic Test System well.
Each for system functional unit is carried out modularization, the cell formation test macro modular with these, certain specific function can be completed, enable system according to test assignment and requirement, rapid build goes out to meet the Auto-Test System of test request, completes test assignment; When test assignment changes, system can set up out the Auto-Test System that can complete new test assignment rapidly again according to new test request.Such Auto-Test System is exactly flexibility testing system.Flexibility testing system be a kind of can according to the change of test assignment demand and test environment, the enterprise schema of quick change system, hardware and software structure, to regulate rapidly test function to adapt to the Auto-Test System of new task and new environment.
Traditional equipment Test system is difficult to consider that the high-level efficiency of test takes into account again the low cost of test simultaneously, does not possess the dirigibility that itself can adjust oneself according to the change of tested equipment Test demand, and poor expandability.Therefore flexible test technology is applied in the design of Auto-Test System, builds flexibility testing system, Auto-Test System can be set up according to the change flexibility of testing requirement, thus reach the effect improving test macro versatility and dirigibility.
