Application of Dewei Chuang Data Acquisition in Large Experimental Data Center
In order to facilitate the collection of test data, the unified management of test data and the overall arrangement of test tasks, many test centers and research institutions have gradually begun to focus on the construction of test data centers. The data center not only includes the above data summary for large test benches, but also includes integrated data centers such as distributed testing, different test benches, and different testing departments. The multiple data transmission modes and data receiving modes of DEWETRON test equipment, as well as the open hardware and software, have a good supporting role for the data transmission, data compatibility, data collection, test grouping management, etc. of the test center. Function of test data center: ① Summary of experimental data, including DEWETRON Self data, including other third-party equipment; ② Remote equipment management, including equipment use status, whether equipment data is uploaded, upload test channel, etc.; ③ Real time monitoring display of test data is used for test status monitoring and data display.
Test Data Center Case (I)
ONERA France Large Wind Tunnel Distributed Test Data Center
Project scale: Europe's largest continuous flow wind tunnel
Test background and system composition:
S1MA wind tunnel is equipped with two counter rotating fans, which are driven by Pelton turbine and provide 88MW power;
Air flow rate: 0.05-1 Mach;
8 meters in diameter, the largest facility of the same type in the world;
Typical model span size: 3.5~4m;
Test system composition: (240 multi-function channels ）
DEWE3-RM16 * 5
TRION-1820-MULTI-8 * 30
OXYGEN-NET
Project characteristics:
➢ There are many kinds of test signals, such as strain, vibration, noise, displacement and temperature;
➢ The test space is large, and the equipment is distributed to reduce the sensor line length;
➢ For different tests, because the test points are different, the data center needs to specifically enable the corresponding equipment;
➢ The central control data center controls the system and obtains test data. Capacity improvement:
➢ Large channel synchronization test / Acquisition capability
➢ The networking of multiple devices does not change the devices that can be locked at any time under the network connection without affecting other devices in the network;
➢ The data center can remotely realize the equipment enabling status, equipment settings and data summary and transmission in the network.
Test Data Center Case (II)
Boeing Multi Test Bench Test Management and Data Center
Project background: The Boeing Test Department has multiple parts and performance test sub departments. Boeing hopes to connect all department test equipment to the same LAN (intranet). The data center can designate a test bench to control the operation through the network. At the same time, it can selectively obtain the test data of a test bench.
Test system composition:
TRIONet * 48 Per six Group by group, distributed on eight Test departments)
All kinds TRION Board ≥ ninety Zhang
Project characteristics:
➢ The number of equipment and channels is large, and the types of test signals are complete;
➢ Multiple test departments and test bench equipment are connected to the same LAN (intranet);
➢ It needs unified control of the data center;
➢ According to the test task arrangement, the designated test equipment shall be enabled and networked without affecting other equipment in the LAN;
➢ The data center controls the use status, setting information and obtaining test data of equipment.
Capacity improvement:
➢ Multi department test-bed equipment networking (intranet) and management capability;
➢ The data center's ability to select and control equipment;
➢ Remote data real-time acquisition and display capability
