Abstract


In recent years, photoelectric devices are widely used in various fields. With the emergence of a variety of remote, mobile, high-precision search and rescue equipment and reconnaissance equipment constantly, measurement, calibration and evaluation of the performance and effectiveness of this type of equipment is very necessary. Traditional test device was largely based on a special test mission equipment and special test equipment, test equipment with the equipment performance increasingly complex equipment increasing number of the test system maintenance and upgrade difficult, seriously affecting the smooth progress of the test security. This test equipment is increasingly unable to meet the needs of the present, so the introduction of universal test ideas, the establishment of the Universal Test System. Universal Test (Universal Test) technology is the core idea is powerful computer resources that would otherwise require hardware implementation of technical software, in order to minimize system cost, enhance system functionality and flexibility in order to achieve versatility. State-of-the-art common architecture and virtual instrument technology into the design of the test system, the researchers versatile system architecture, modular instruments, plug-and-play features such as PCI / ISA bus Universal Test System, theoretical and real value. Automatic test system first analyzes the domestic and foreign research status, system upgrades and expansion for the test system by the issue of limiting the centralized architecture, design and implementation of a universal testing system based on PCI / ISA bus. The versatility of design, on this basis, the PCI / ISA optoelectronic devices Universal Test System needs analysis to complete the design of the test system. PCI and ISA bus is selected according to the actual needs of the system, the formation of a common test platform based on the two bus development environment VC 6.0 was designed and developed based on the PCI / ISA bus universal test system software, and according to the function by different module development are described. Depth study of the optoelectronic devices Universal Test System specific implementation of the key technologies employed in the process of software and hardware integration technology. In this paper, based on the design on the PCI / ISA bus-based optoelectronic devices Universal Test System analysis, combined with the study of key technologies, the development of this test system. The system combines image acquisition, data acquisition, data processing, system calibration and other functions into one, a performance test platform, has a strong practical value and application value.
