Embodiment Construction
[0041] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0042] like image 3 As shown, the marine geophysical prospecting equipment is mainly composed of instruments and equipment on the geophysical prospecting ship (not shown in the figure) and underwater tow cables. The underwater towline is powered by a 380V high-voltage power supply on the geophysical exploration ship during normal operation. In order to ensure the safety of the equipment during this process, it is necessary to monitor the power supply process in real time. This is also the background and application field of the present invention.
[0043] 1. Power-on process of marine geophysical cable equipment
[0044] like image 3 As shown, the marine geophysical cable is composed of multi-level digital packages. From the perspective of safety, when the high-voltage power supply on the geophysical survey ship supplies power to the underwa...

The invention relates to an FPGA-based marine geophysical prospecting towing cable's real-time power supply monitoring device, which comprises a geophysical prospecting instrument control device, an FPGA system and a high-voltage power source device. When the geophysical prospecting towing cable device is in the stable power-on state, the power source is monitored through the FPGA system, and the comparison result is processed correspondingly through the response of the high-voltage power source device. The high-voltage power source device then returns the corresponding processed result to the geophysical prospecting instrument control device. According to the invention, through the monitoring circuits of the high-voltage power source, the power source data are acquired; and in close combination with the power supply characteristics for a geophysical prospecting towing cable device and through the FPGA system for power source monitoring, the power source monitoring for the geophysical prospecting towing cable device becomes real-time, safe, effective, convenient and fast.
Description
technical field [0001] The invention relates to an FGPA-based real-time power supply monitoring equipment for a marine geophysical prospecting cable, belonging to the technical field of marine geophysical prospecting. Background technique [0002] According to operational requirements, the length of marine geophysical cable equipment can generally reach the order of 6 to 12 kilometers. Generally, marine geophysical cable equipment is composed of multiple cable units connected in series through digital packets. There is a dedicated power supply system in the digital package, so as to realize the normal power supply of the whole tow cable. [0003] During operation, due to the limitation of the length of the towline, the marine geophysical cable equipment must provide high-voltage power supply through the power supply equipment on board, so as to realize the long-distance power supply capability. In order to ensure the normal and safe power supply of the underwater system, t...
