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

Abstract

The invention provides a clock synchronization network, a clock trigger network and a real-time trigger processing method. The clock synchronization network comprises N clock trigger modules which are used for obtaining and transmitting communication information and outputting a synchronous clock, wherein each two clock trigger modules can transmit the communication information to each other; N front-end acquisition module groups which are arranged corresponding to the clock trigger modules and are used for receiving the synchronous clock and the time service information, synchronously acquiring acquisition data in real time and outputting sub-trigger information to the corresponding clock trigger modules, wherein each front-end acquisition module group comprises at least one front-end acquisition module, and the front-end acquisition module is suitable for synchronously acquiring signal waveforms in real time and acquiring acquired data. According to the clock synchronization network disclosed by the invention, synchronous time service, real-time control and trigger interaction among distributed nodes can be realized by only using one transmission network, and global time service and control system deployment are greatly simplified.

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...

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-t
