Embodiment 1

[0028] Embodiment 1: The overall design block diagram of multi-channel synchronous acquisition and centralized storage technology is as follows figure 1 shown. The main hardware inside the navigation body includes a synchronous circuit board, a digital stream conversion circuit board, a signal processing module, a computer, an acoustic receiver and an electromagnetic receiver. The external equipment includes 3D synchronization equipment, whose function is to synchronize the synchronization circuit board in the vehicle body, and unify it with the 3D segment installed on the product to the same time reference. The synchronous circuit board generates synchronous signals, and transmits the synchronous signals to the acoustic receiving component, the electromagnetic receiving component and the digital stream converting circuit board in the form of RS485. The acoustic receiving component and the electromagnetic receiving component perform synchronous sampling on the received acoust...

Embodiment 2

[0037] Embodiment 2: a method for multi-channel synchronous acquisition and centralized storage, comprising the following steps:

[0038] Step S1, the 3D synchronization device is synchronized with the synchronization circuit board, so that the 3D segments are unified to the same time reference, and a synchronization signal is generated, and synchronously output to each underwater acoustic receiving device and digital stream conversion circuit board module; Step S2, each underwater acoustic receiving device Carry out synchronous sampling to the received acoustic signal and electromagnetic signal according to the received synchronous signal, and transmit the sampled digital signal to the digital stream conversion circuit board module; step S3, the digital stream conversion circuit board to the data of all nodes received Arrange to form a frame of data, fix the relative position of each node data, organize and pack, and transmit to the signal processing module; step S4, transmit ...

Abstract

The invention discloses an acoustic signal multi-channel synchronous acquisition and centralized storage system and a method, and relates to a whole set of technologies of an overall design scheme, hardware design implementation and software development. According to the technology, a plurality of sampling points which are widely distributed and are far away from one another can be synchronously acquired. Collected data are gathered and stored in a centralized mode, data dislocation and other situations do not occur in the transmission and storage process, and data snapshots formed by multiplechannels at each moment are well stored. A computer is used for storing data, and data storage capacity is large. And a user can read and analyze data very conveniently. The hardware channel expandability is good, and the reliability, the integratability, the universality and the expandability are high.

Description

technical field [0001] The invention belongs to the technical field of underwater weapon testing and testing, and can also be popularized and applied to civilian fields with similar conditions, specifically a multi-channel synchronous acquisition and centralized storage system and method for acoustic signals. Background technique [0002] When using moving targets to carry out assessment tests such as the amount of misses and electromagnetic fuzes on underwater weapons, it is necessary to simultaneously collect and centrally store the widely distributed electromagnetic and acoustic channels. Synchronize with GPS signal so that all channels are based on one time. [0003] The distance between the target and the target is calculated by using the time delay of the target acoustic signal reaching the receiving transducer to measure the amount of miss. When the 3D segment of the cooperative beacon is used to measure the amount of miss, the distance of the target can be calculate...
