Abstract

The invention relates to a multi-channel signal acquiring system belonging to the technical filed of digital signal processing. The system comprises: one clock module, two double-channel high speed data acquisition module, eight NAND storage modules, one unloading module, one secondary baseboard module, one main control module and one client end module, the analog signals can be acquired and stored in real time by four-way 900 MHZ sampling rate, the system has 3 TB storage capacity. The invention adopts the NAND storage body as the storage medium, has advantages of small facility volume and low power consumption, the synchronization consistency of four-way acquisition channel can be implemented by the synchronization processing of a clock enable signal, a sampling trigger signal and a sampling clock and the accurate design of a signal delay.

Description

technical field [0001] The invention relates to a multi-channel signal acquisition system, which belongs to the technical field of digital signal processing. Background technique [0002] Data storage devices are widely used in various industries such as radar, industrial automation, medical and health care, and communications. Due to the different environments in which the devices are used, their implementation methods are also different. How to make it as economical, convenient, and practical as possible under the premise of meeting the performance requirements is still an important reason for the continuous innovation of data storage research. In the research of modern data storage systems, especially in embedded applications, how to achieve high-speed data acquisition and mass storage, and realize data playback and reproduction under the condition of limited volume and power consumption has become a current research hotspot. For example, in the radar receiving system, i...
