Multi-source data time delay control and clock synchronous acquisition method in radar testing

Abstract

The invention discloses a multi-source data time delay control module in radar testing, which comprises a cloud data platform, the cloud data platform is in signal connection with an acquisition upper computer, and the acquisition upper computer is in signal connection with a multi-source data time delay control module and a synchronous acquisition module. The multi-source data time delay control module and synchronous acquisition module comprises a video module, a radar module, a GPS module and a vehicle body module, and the input end of the multi-source data time delay control module and synchronous acquisition module is in signal connection with the video module, the radar module, the GPS module and the vehicle body module. The method has the beneficial effects that radar data, video data, vehicle body data and GPS data can provide a clock through a CAN line and an Ethernet interface, and each module transmits a correct clock signal to cooperate with a master clock and a slave clock by deploying and collecting data processing of an upper computer; different information modules are respectively connected with the switch in different forms, and a single subsystem or a plurality of subsystems are established for clock calibration, so that working synchronization of a plurality of acquisition devices is realized.

Description

technical field [0001] The invention belongs to the technical field of data acquisition methods in radar testing, and in particular relates to multi-source data delay control and clock synchronization acquisition methods in radar testing. Background technique [0002] With the continuous development and improvement of network technology and the continuous progress and innovation of synchronization technology, the industrial and electronic industries have higher requirements for synchronization accuracy, synchronization method and delay control. The time deviation caused by different time standards and delays may not only delay the data, but even lead to the reversal of the data in severe cases. It is impossible to establish a single or multiple subsystems for clock calibration and to realize the synchronization of multiple acquisition devices. The data collection work lacks convenience and breakthrough. Contents of the invention [0003] In view of the problems raised by ...
