Abstract
The invention relates to an automatic VPX testing system, in particular to performance testing and high temperature and low temperature testing of various types of VPX board cards. The automatic VPX testing system consists of a high temperature and low temperature box, a testing case, a VPX system board (exchange board) adapter board, a VPX power adapter board, an adapter back plate in the high temperature and low temperature box and an adapter back plate in the testing case. By using the automatic VPX testing system, the various types of VPX board cards can be subjected to independent performance testing and high temperature and low temperature testing, and accurate data parameters of the board cards which run at different environment temperatures can be measured. The existing VPX system platform only can be tested integrally, and a board card of the existing VPX system platform cannot be tested independently, so that performance parameters and high temperature and low temperature data of the board card cannot be acquired. By using the automatic VPX testing system, the requirements on performance testing and high temperature and low temperature testing of VPX board cards in the industry can be met.
Description
Technical field
The present invention relates to VPX automatization test system, relate in particular to performance and the high low-temperature test of all types of boards of VPX, this VPX automatization test system provides the performance test of VPX board specialty, the VPX application industry of Aviation, carrier-borne, radar, sonar, video image processing, military solid-state storage, and VPX board manufacturer.
Background technology
VPX bus is that VITA (VME International Trade Association, VME international trade association) is organized in the high-speed serial bus standard of new generation proposing on its VME bus basis for 2007.The particular contents such as fundamental norms, physical construction and the bus signals of VPX bus all define in ANSI/VITA46 series technique specification.
VPX bus is the natural evolution of VME technology, and it is its main variation that VPX adopts high-speed serial bus to substitute parallel bus.The current up-to-date serial bus technology of VPX bus support, for example: the universal serial bus of the height such as Rapid IO, PCI-Express and 10G Ethernet.
These high speed serialization exchanges can provide the data transmission rate of each differential pair 250MBytes/sec.If 4 channels Theoretical Rate of the highest 1GBytes/sec.The core exchange of VPX provides 32 groups of differential pairs, forms 44 channeling ports, and each channel is two-way (a pair of transmission difference, a pair of reception difference).The theoretical aggregate bandwidth of VPX module is 8GB/sec.
In order to meet in national defence and aviation field the requirement of VPX system reliability, existing VPX system platform system test cannot ensure validity and the authority of its test result, because of cannot be to board in system, carries out independent performance and high low-temperature test.
I take charge of the VPX automatization test system of independent development, in such technical background and market demand environment, develop.
Summary of the invention
The technical problem to be solved in the present invention is to the various VPX boards based on VPX bus architecture, provides performance and high low-temperature test to it.
VPX automatization test system of the present invention, formed by parts such as high-low temperature chamber, test cabinet, system board (power board) card extender, VPX power supply backplane, high-low temperature chamber entodorsum, test cabinet entodorsums, this VPX automated test device can carry out performance and high low-temperature test to all types of VPX boards, be characterized in: this VPX automatization test system can be supported two kinds of physical constructions conduction cooling board structure and ventilation panel card structure.
This VPX automatization test system is also equipped with VPX power source special to system power supply.
This VPX automatization test system can meet 0.8 ", 0.85 ", 1 " the test board of three kinds of specification height dimensions.
Because VPX automatization test system can carry out independent performance and high low-temperature test to each board in VPX system, can measure board in the operating accurate data parameter of various environment temperatures.And existing VPX system can only be carried out system test and can not separately its board be tested, so cannot obtain performance parameter and the high low temperature data of board.VPX automatization test system has solved the testing requirement to VPX board performance and high low temperature in industry.
