Problems solved by technology

However, the current wireless network itself does not support the synchronous collection of test data from multiple test nodes. Clock synchronization is not performed between test nodes, or clock synchronization still needs to be achieved by external hard-wired connections or GPS, which increases the complexity of the test system. Limits the application environment of the test system

Embodiment Construction

[0026] Below with reference to the drawings of specific embodiments of the present invention will be described. It should be appreciated that only the preferred embodiments shown in the drawings embodiment of the present invention, which do not limit the scope of the invention. Those skilled in the art may be made on the basis of the embodiment shown in the drawings embodiments of the present invention on various obvious modifications, variations, equivalents, and does not contradict the premise of the embodiment described in the art in the embodiment It can be any combination of features, which are within the scope of the present invention.

[0027] As described above, the prior art test node still needs large test network wired connection, at least a need for clock synchronization cable, leading to the lifting system complexity, it is difficult to maintain discharge problems. To solve such problems, embodiments of the present specification provides a test system based on multi-n...

Abstract

The invention discloses a multi-node test system, and the system can comprise: a central server which is used for transmitting a test instruction and receiving test data; and multiple test nodes, wherein one or more of the plurality of test nodes receive a test instruction from the central server, execute a test according to the test instruction and transmit test data to the central server, and the central server and the plurality of test nodes execute clock synchronization, so that the central server and the plurality of test nodes are consistent in clock. The multi-node test system can provide reliable test results and reduce wiring. The invention further discloses a multi-node test method by using the multi-node test system.

Description

Technical field [0001] The present invention relates to large-scale testing systems and more particularly relates to multi-node test system. Background technique [0002] Currently, some large-scale test system requires extensive testing including test network node to perform the test. [0003] For example, to perform aircraft (such as civil aircraft, etc.) tests required laboratory tests, such as testing machine on the ground. Moreover, both laboratory tests or test machine on the ground, test platform are very large, complex test configuration, the number of sensors used for testing the test dispersion and arranged. [0004] Existing test systems wired test program, cable management workload trial site, the cable complicated, maintenance and troubleshooting difficult. Using a wireless network technology, wireless testing large multi-node test. But the wireless network does not support a plurality of test nodes synchronous acquisition test data, the clock synchronization is not ...
