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...

AI Technical Summary

Problems solved by technology

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] The existing clock synchronization network often has the following limitations: the tree topology network used in the prior art is unidirectional, which can only realize the distribution of synchronous clock and control information, and it is difficult to support the real-time interactive transmission and processing of trigger information

Additional construction of trigger network makes the system very complex

[0004] Therefore, in order to ensure the synchronization accuracy of data acquisition, the existing clock synchronization network is difficult to realize real-time interaction of multi-level trigger information, synchronous timing and technical problems that the network structure is difficult to expand.
