Task distribution device based on distributed test system and cooperative control method thereof

Abstract

The invention discloses a task distribution device based on a distributed test system and a cooperative control method of the task distribution device. The task distribution device comprises a test task management unit and a plurality of test task processors connected with the test task management unit. Each test task processor is correspondingly connected with an acquisition and excitation device, and the plurality of acquisition and excitation devices are connected with a tested unit through a plurality of signal switching matrixes and data switching devices; the test task management unit is used for decomposing and distributing test tasks and configuring test resources; the test task processor undertakes and executes the test task; the acquisition and excitation equipment acquires feedback signals and data of the tested unit through the signal switching matrix and the data switching equipment and sends control signals and data to the tested unit; and the signal switching matrix and the data switching device realize switching multiplexing of the tested unit and the plurality of acquisition and excitation devices. According to the invention, automatic distribution and cooperative control of test task optimization can be realized.

Description

technical field [0001] The invention relates to the field of equipment testing, in particular to a task distribution device based on a distributed testing system and a cooperative control method thereof. Background technique [0002] The distributed aviation test system needs to conduct online tests on multiple aviation subsystems and equipment at the same time. In the prototype design, simulation modeling and test verification of complex hardware cross-linking application systems, due to the inconsistency of the hardware environment, operating system or interactive interface of different subsystems and different devices, real-time data collection, mapping, When calculating and distributing, it is necessary to design an applicable data processing system to meet different needs, and it is not universal. [0003] Data Distribution Service (DDS, Data Distribution Service) technology is first applied to software platforms and communication systems. For the subsystems of modern ...

AI Technical Summary

Problems solved by technology

[0004] However, when DDS is directly used for the distribution and scheduling of test tasks in a distributed test system, there are the following problems: first, it is necessary to solve the parallel execution and serial execution of test tasks in a distributed environment; Sequence control issues such as follow-up work and parallel work; at the same time, it is also necessary to solve the problem of coordination of multiple test tasks in limited test resources; finally, it is also necessary to consider the dynamic adjustment of test tasks when test failures occur

But it does not solve the problem of timing control and collaborative testing

[0008] To sum up, the existing test system mainly relies on manual configuration for timing control and collaborative testing of test tasks in a distributed environment, and does not provide an effective method for dynamic adjustment of test tasks caused by test failures or problems.
