Based on "soft test" of the military test system design technology - electronics industry

Modern military test system faces new challenges

Level of development of modern science and technology, military weapons and equipment system updates faster and deeper complexity, Electronic Increasing degree, etc., these military-industrial complex in the appearance of new features, making military test systems tested various types of signals, the correlation between signals in close, post signal analysis process more difficult. The same time, military industry specific environmental requirements, but also to test equipment is relatively harsh operating environment.

The characteristics of the modern defense industry requires us to test systems to fully consider the following aspects of their needs.

1. Test reliability of the system requirements: This reliability, including software and hardware platform of reliability, the development of the platform itself should have high reliability, and asked the selected platform to have a certain degree of long-term supportive.

2. Test system accuracy requirements: reflected in the measurement precision, accuracy, and number of channels so.

3. Test the adaptability of the system requirements: for the modern military test systems of many types of signals under test, test steps and flexible features, testing for the test system should provide maximum customizable multi-function adaptive space, regardless of test steps or hardware resources, can be flexibly configured, truly tailored, with the required moves.

4. Test system scalability needs: from the rapidly changing trends to consider the need for the test system provides a wide range of expansion space to ensure its maximum reuse, reduce development cycles and costs.

Meet the military industry test System Requirements "soft test" of modern military technology industry, according to development needs, combined with Global China Military Control over the years in the field of hard practice test, measurement and control is leading the Global China proposed a testing of the core technology? " Flexible test "techniques. It is based on virtual instrument technology, test and measurement technology, mechatronics, software technology, Communicate Based and network technology to test the system's accuracy, reliability, adaptability, flexibility, and expansion of the research objectives, concerned about the overall function of test and measurement systems and performance, to meet the system requirements test and measurement methods and means in-depth study of one technology. "Soft test" technology proposed is in line with the military industry test system reliability, accuracy, adaptability and scalability needs of its military industry, not only to guide the test system set up, it must be the current test technology development in China trend.

Through the practical application of the following cases to illustrate how to build a military industry to meet the various requirements of the test system. Basic platform of choice

Hardware platform Modern military test systems for multi-signal type and a high degree of correlation between signal characteristics and the combination of "soft test" technology in the pursuit of test reliability, adaptability, scalability and other key design requirements, we selected computer-based high-reliability platform PXI.

Course, the choice of hardware platform, there are many options to choose from, we chose to meet the needs of defense industry, while better in the field of test and measurement program. PXI not only avoids the use of ordinary PC, in transport, environment, working conditions, the pressure, and avoided the use of traditional test instruments for bringing the low reusability and cost issues. Not only from the quality of the PXI platform to meet the reliability, performance and other requirements, the modular structure also makes the applicability and scalability can be protected.

Applications

A general-purpose test system shown in Figure 1, is based on the PXI-SCXI chassis mixed construction, the adaptive system with a high signal, with the pressure, voltage, temperature, frequency, speed and other different types of signals collection capacity, a significant reduction in hardware costs, achieve the unity of different types of integrated signal measurement.
