Considering high false alarm probability of BIT and oversize of off-line ATE, the paper studies and designs an online automatic test system. The interface signals of radar line replaceable units (LRU) on working condition are leaded out by three-port conversion card and conditioned with insulation technology,...

The hardware platform of real-time measurement and control system composes of PXI, WT3000, the dynamometer, the tested motor, the controller and so on. Its PC platform’s software is compiled by LabVIEW. The remote control, dynamic and static load output, real-time data acquisition, road situation-simulate...

In order to achieve the test of function and strategy of pure electric car vehicle control unit(VCU) better, this paper designs a hardware-in-the-loop (HIL) test system for VCU based on NI-PXI platform. Firstly, expounding the principle of HIL testing technology and introducing the HIL test system plan...

Based on LAN bus technology LXI instrumentation bus is a new generation after GPIB, VXI, PXI instrument bus, and it is also applicable for automation test system in the field of test and measurement. With the rapid development and popularity of the LXI instrument, more and more LXI instruments are used...

It is an important way to research the IC engine combustion process by calculating the heat release rate from the cylinder pressure. Basing on the NI PXI-8196 embedded platform system, the PXI-6229 multi-function data acquisition card is put into use to realize cylinder pressure curve point sampling,...

It is incidental for current automatic test system (ATS) to lead short of circuits, damage of instruments or units under test (UUT) by reason of its large amount of switches. To solve the problem, the technique of reconfigurable instrument is introduced. Using the reconfigurable instruments as substitutes...

LXI is a new modularization instruments platform standard for automation test system based on Ethernet LAN after GPIB, VXI, PXI instrumentation bus. A type of LXI Distributed test system architecture was given out based on the development of instrumentation bus, LXI bus system structure and main characteristics,...

This paper examines the rise of “New Painting” (新绘画) in post-millennium China, positioning it as a critical evolution beyond historical movements like Scar Art (伤痕艺术), the '85 New Wave (85新潮), and Political Pop (政治波普). Rather than a unified style or manifesto, New Painting embodies a radical subjectivity—a...

A high precision clock system is required in the external target experiment of the Cooling Storage Ring (CSR) project in the Heavy Ion Research Facility in Lanzhou (HIRFL). Considering that the detectorsare located in different places of the experimental hall, a high quality clock signal is required...

O-E theodolite is consisted of the subsystems. At present, each subsystem is emplaced separately and connected by cables, which leads to a comparably enormous volume. Therefore, the application of PXI bus technology is optimum that allows inserting every subsystem in a PXI chassis thus largely reduce...

Based on Ethernet, LXI is a new generation modularization equipment platform standard. Comparing with GPIB, VXI and PXI buses, LXI bus provides many more advantages, such as networked, lower price, higher performance and smaller dimension. This article makes a full introduction of LXI bus and its key...

In order to improve the accuracy of the test of the satellite navigation receiver, the method of automatic test was adopted in this paper, and combined with PXI hardware platform, an automatic test system for receivers has been developed. This system has the function of parallel automatic test, and support...

Target seeker is a key component of missile, whose tracking performance in real guidance phases can be guaranteed by performance testing in its design stage. Generally, multi-sets of equipment are used in conventional testing method, which takes on some disadvantages of sophisticated operation and low...

This cold-rolling simulator is mainly used for exploitation of new productions and research for new technique. The execution system of this cold-rolling simulator includes hydraulic drive system and electric drive system. The features, such as multivariable, nonlinear, real-time, and high-speed, set...

Energy management of isolated micro-grid with wind turbines and seawater desalination devices is of great significance to the use of wind power, the supply of fresh water resources and the economic operation of micro-grid. This paper established isolated micro-grid model including wind turbines, seawater...

In debugging and testing process of the intelligent substation process level intelligence unit ,it need to build multiple sets of test environments, with the wiring complexity and low efficiency. For this case, we design of a portable intelligent substation testing device based on PXI bus, describe the...
