Control type communication system in sonar signal processor

Abstract

The invention relates to a control type communication system in a sonar signal processor. The control type communication system comprises the components of a master control node, a Gigabit Ethernet switch module, a power supply management module, a clock distribution module, a clock synchronous self-checking generating module, a PCI bridging module, and an FPGA logic loading and debugging module; wherein the Gigabit Ethernet switch module, the power supply management module, the clock distribution module, the clock synchronous self-checking generating module, the PCI bridging module, and the FPGA logic loading and debugging module are connected with the master control module. The clock distribution module is further connected with the Gigabit Ethernet switch module. The power supply management module supplies electric power to other modules.

Description

technical field [0001] The invention relates to the field of sonar systems, in particular to an in-machine control communication system for sonar signal processing. Background technique [0002] A sonar system mainly consists of two parts: the dry end and the wet end. As the name implies, the dry end is the part above the water, and the wet end is the part below the water. The dry end is mainly composed of a signal source, a transmitting device, a signal processor, and a discrimination display machine. The wet end is mainly composed of hydroacoustic transducers or transducer arrays. When the sonar system is working, the signal source in the dry end device transmits the signal through the transmitting device, the signal propagates and reflects in the water, and then the echo signal is collected by the sonar wet end device, and the collected echo signal is transmitted to the dry end The signal processing unit of the equipment does further processing, and finally the final d...

Problems solved by technology

[0004] First of all, the number of trunk lines inside the sub-cables has doubled, which increases the difficulty of cable formation; secondly, since the original pair of connectors has been changed into two pairs of connectors for each cable, it is equivalent to connecting four pairs of connectors between two adjacent sub-arrays. , has a great impact on the quality of signal transmission; the most critical factor is that all the acquisition nodes of this scheme are connected in series, and any point of network failure will cause data loss after the point of failure, with high risk and no guarantee of reliability
