Abstract

The invention discloses a signal acquisition system. A first synchronizing signal is serialized through a second signal processing device, the serialized first synchronizing signal is transmitted to afirst signal processing device through a serial transmission cable, then the first synchronizing signal is deserialized through the first signal processing device, and the deserialized first synchronizing signal is transmitted to a first sensor. Thus, in the signal acquisition system with the signal synchronous acquisition demand, the technical effect that the first synchronizing signal can be subjected to long-distance transmission is achieved; and the technical problem that in a signal acquisition system, with the signal synchronous acquisition demand, in the prior art, the synchronizing signals cannot be subjected to long-distance transmission is further solved.

Description

technical field [0001] The present application relates to the field of signal acquisition, and in particular, to a signal acquisition system. Background technique [0002] Measurement technology based on various types of information (such as image information) is widely used in industry, aviation and other fields Carry out measurement and processing, and complete the control of the ocean by analyzing and researching various information obtained. Related signal acquisition equipment such as multi-channel camera display, radar array, and millimeter wave array all need synchronization device triggers to calculate accurate Data and related location information, and the collected signals are transmitted to remote signal processing equipment. However, the synchronous signal has the problem of signal attenuation as the transmission distance increases. Therefore, in a signal acquisition system that requires synchronous signal acquisition, how to realize long-distance transmission ...
