Clock synchronization network, clock trigger network and real-time trigger processing method

Abstract

The present disclosure provides a clock synchronization network, a clock trigger network and a real-time trigger processing method, wherein the clock synchronization network includes: N clock trigger modules for acquiring and transmitting communication information and outputting a synchronization clock, wherein every two clocks Communication information can be transmitted between trigger modules; N front-end acquisition module groups, set corresponding to each clock trigger module, are used to receive synchronous clock and timing information, acquire acquisition data synchronously in real time, and output sub-trigger information to the corresponding The clock trigger module; the front-end acquisition module group includes at least one front-end acquisition module, and the front-end acquisition module is suitable for real-time synchronous acquisition of signal waveforms and acquisition of acquisition data. The clock synchronization network in the present disclosure realizes synchronous timing, real-time control and trigger interaction among distributed nodes with only one transmission network, which greatly simplifies global timing and control system deployment.

Description

technical field

[0001] The present disclosure relates to the field of clock synchronization control of experimental physics, in particular to a clock synchronization network, a clock trigger network and a real-time trigger processing method. Background technique

[0002] In order to ensure the synchronization accuracy of data collection, the current large-scale physical experiments generally adopt the clock synchronization network architecture of star or tree network. There is a master clock module on the root node of the network, and its slave modules are distributed in the rest of the network. On different leaf nodes, thus forming a master-slave synchronous clock and a fan-out mode of control instructions. At the same time, in experimental physics, it is often necessary to build a real-time trigger network to eliminate invalid cases and reduce the system data rate.

[0003] Existing clock synchronization networks often have the following limitations: the tree topology net...
