Embodiment 1

[0036] This embodiment provides a method for designing a synchronous board for a dynamic data acquisition system. Dynamic data acquisition system of the present invention uses synchronous board design method:

[0037] see figure 1 and figure 2 In this application, the dynamic data acquisition system uses a synchronous board design method, comprising the following steps:

[0038] Step 1: The SYNC clock sends the information to the slave clock, and broadcasts the synchronization information regularly according to the fixed synchronization period as the time period. Each message includes a sent timestamp, indicating the reference time when the master clock initiates synchronization in the K time period.

[0039] Step 2: FOLLOW_UP the information sent by the master clock to the slave clock, record the time stamp TSYNC,MK at the moment when K times SYNC information is sent, and send the time stamp TSYNC,MK after each SYNC information.

[0040] Step 3: The delay request message...

Abstract

The invention relates to the technical field of signal synchronous acquisition and control, and provides a synchronous board card design method for a dynamic data acquisition system, which realizes the high-speed synchronization of each board card based on an IEEE1588 protocol and realizes the functions of high-precision acquisition, real-time processing, analysis and the like of dynamic data. Theclock topology is studied by using the combination of different elements (daisy-chain) of the PTP network. Four types of synchronous protocol information of the PTP are SYNC, FOLLOW _ UP, DELAY _ REQand DELAY _ RESP respectively. According to the synchronous board card design method for the dynamic data acquisition system, the problem of board card synchronization for dynamic characteristics atpresent is solved, a synchronous control method is simplified on the premise that functions are guaranteed, and the synchronous board card design method is suitable for achieving high-speed synchronization of all board cards and achieving the functions of high-precision acquisition, real-time processing, analysis and the like of dynamic data.
