Embodiment

[0087] A synchronization system for a large-scale collection array, including a synchronization signal distribution device, multiple collection devices, multiple collection device sub-cards, and multiple collectors;

[0088] The synchronization signal distribution device distributes N clock signals and N synchronization signals to the acquisition device through its internally configured clock and synchronization signal distribution module;

[0089] The acquisition device distributes M-channel clock signals and M-channel synchronization signals to the acquisition device sub-card through its internally configured synchronization signal distribution module;

[0090] The acquisition device sub-card distributes L-way clock signals and L-way synchronization signals to the collector through its internally configured synchronization signal distribution module;

[0091] Wherein, the sub-card of the acquisition device is provided with a synchronization signal automatic alignment module ...

Abstract

The invention discloses a large-scale acquisition array synchronization system, which forms an array supporting N*M*L collectors, wherein N, M, and L can be adjusted according to specific conditions, that is, each acquisition device, sub-card, acquisition The number and types of devices can be flexibly expanded. The clock signal and synchronization signal are distributed layer by layer to form a tree structure. The distribution process only involves PCB routing, chip internal routing, and signal frequency division, thereby forming a homologous and phase relationship. Fixed tree structure; the structure is simple to implement and does not need to analyze the relative or absolute delay relationship between signals; not only can the array be realized in a large scale, but also has strong scalability, and the configuration of the array can be changed at any time.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a synchronization system for large-scale acquisition arrays. Background technique [0002] In the application of aircraft flight test measurement and control, due to many test points and scattered test points, it is often necessary to use multiple devices to complete on-site acquisition and monitoring; at the same time, due to the special requirements of the application, for example, the vibration and noise of large aircraft mechanical equipment The monitoring system must collect these scattered measuring points synchronously in order to conduct a complete and accurate analysis of the overall status of the equipment. The synchronous collection here not only requires all test channels to start collecting at the same time, but also requires all channels to share a clock signal. The traditional multi-device synchronization needs to share the two digital signals of the trigger...
