Large scale system test platform with high bus rate and memory rate
Facing the complexity of the structure of test components, more test points need to be arranged to obtain detailed data parameters. Especially for the test of large engines, large hydraulic control systems, large wind tunnels and large vibration tables, more test channels are usually required to build test platforms. At this time, we need to ensure that the test data can be reliably stored under large channels and high sampling rates. The traditional RS bus, PCI bus and other forms cannot guarantee normal storage under such test conditions. Therefore, in general, the solution of the traditional bus is to reduce the number of channels of a single device to reduce the drawbacks of the traditional bus for streaming disk data storage: many test devices need to be networked. Is the synchronization guaranteed? Is the data storage of multiple devices complete? Data cannot be summarized, and there are many data processing files.
Devtrone's PXI/E bus advantage: the AD board based on PXI/E can guarantee the maximum data transmission rate of a single card up to 200MB/S. The storage mode of Devtrone's DEWE3 series chassis is also optimized, and its data storage rate can reach 1GB/s. That's why DEWETRON A single 128 channel chassis can be used and high-speed data storage can be realized.
Large test platform
In the previous discussion, we mentioned that in the face of test tasks such as large engines, large hydraulic control systems, large wind tunnels and large vibration tables, the construction of large test platforms will gradually increase due to the complex structure, many test points and complex sensor types, so as to meet the test work of different types of products and different test tasks. Features of large test platform:
① The equipment supports signal diversification;
② Reliable data transmission and storage;
③ There are many channels;
④ Multiple devices can be networked and transmit data;
⑤ High synchronization between channels can ensure the unification of time system signals and the phase of test signals
Based on the function description in the previous part of the article, DEWETRON equipment can perfectly meet the test requirements of large test platforms, and achieve stable and reliable performance in actual testing.
