Real-time environmental testing and analyzing device and method for ship's integrated electric propulsion system based on LabVIEW platform

Abstract

The present invention provides a real-time environmental testing and analyzing device and method for a ship's integrated electric propulsion system based on LabVIEW platform. The system comprises three logarithmic cycle antennas, a PXI chassis and a host computer. The PXI chassis is embedded with three 5624R IF digitizers; the three logarithmic cycle antennas are arranged around a piece of to-be-detected equipment to acquire and measure ambient electromagnetic radiation signals in real time and the signals are inputted into the three 5624R IF digitizers respectively; the 5624R IF digitizers perform programming through the LabVIEW FPGA module on the LabVIEW software platform and convert the simulation signals measured by the logarithmic antennas into digital signals; and the data processed by the FPGA are transferred into the host computer; therefore, real-time visualization of environmental data is realized. The invention integrates the hardware equipment, the software framework and the advanced algorithm organically and deeply analyzes and studies the complex testing mechanism of the integrated electric propulsion system so as to improve the testing speed and precision in a complex environment.

Description

technical field [0001] The invention relates to a real-time environment data acquisition device and method for a comprehensive electric propulsion system of a ship. Background technique [0002] In the integrated electric propulsion system of large ships, due to the large number of electrical equipment and the complex electromagnetic environment, when the on-site test of electromagnetic radiation is performed on the key equipment of the system, it is susceptible to electromagnetic interference from other equipment. In addition, the test object of common electromagnetic radiation test equipment Most of them are small and medium-sized board-level equipment or a certain equipment, which lack effective test devices and test methods for system-level electromagnetic radiation tests such as large-scale ship integrated electric propulsion systems, and it is difficult to meet high requirements for test speed and test accuracy. How to realize the on-site test of the large system platf...

Problems solved by technology

On the other hand, data processing in the host computer is only suitable for the case of small data volume, and when testing the electromagnetic radiation of large-scale equipment, because the frequency band to be tested is wide and the sampling frequency is high, the amount of sampled data is relatively large. Large, digital signal processing in the host computer has high requirements on hardware equipment, and ordinary host computers are often difficult to meet the hardware and real-time requirements
