Method and device for self-synchronizing data acquisition system

Abstract

The invention provides a method for self-synchronizing a data acquisition system. The invention aims to firstly provide a method for realizing hardware counters by using a CPLD (Complex Programmable Logic Device) and keeping counters between different data acquisition apparatus or between different board cards of the same apparatus in the same counting value, or controlling the counting value error in the counting values in a certain range via a time-delay calculation and a real-time synchronization adjustment method. The apparatus can add time information to each acquired data packet according to the counting values so as to ensure sequence between the different apparatus or board card acquisition data, thereby realize the self-synchronizing of the whole system. The invention provides a self-synchronizing method which is low in cost, easy for implementation, and capable of automatically adjusting according to network state of the apparatus; the method is mainly used for self-synchronizing internal part of the data acquisition apparatus and among the data acquisition apparatuses, and also can be used for the electronic apparatus with other synchronizing requirements.

Description

Method and device for realizing self-synchronization of data acquisition system (1) Technical field: The invention is a new method for the self-synchronization of the data acquisition system. It is mainly used for self-synchronization within and between data acquisition devices, and can also be applied between electronic devices with other synchronization requirements. (two) background technology: Data acquisition equipment in the communication field usually collects data between various interfaces in the mobile communication network for data analysis and signaling processing, so as to know the status of the current mobile network. Since the devices used need to be connected to different ports, a self-synchronization system is required between different boards of the same device and between different devices to distinguish the sequence of each collected data packet. Only in this way can the correctness of the collected data be guaranteed during analysis and use. There ar...

Problems solved by technology

For example, GPS requires an external antenna, 1588 technology requires the support of synchronous Ethernet, etc. Therefore, under the conditions of use where data acquisition equipment is often placed together with mobile communication equipment, these methods are often limited and difficult to implement
