Abstract

The invention discloses a vehicle magnetic field frequency domain data measurement system, which comprises a field intensity meter, an oscilloscope and an upper computer which are connected in sequence, wherein the field intensity meter is used for measuring the real-time signal intensity of a magnetic field environment where a vehicle is located when the vehicle runs and inputting the real-time signal intensity into the oscilloscope, the oscilloscope is used for reading real-time time domain data corresponding to the real-time signal intensity, carrying out frequency domain analysis on the real-time time domain data, and calibrating frequency parameters according to preset configuration in the frequency domain analysis process so as to output calibrated real-time frequency domain signal amplitude, and the upper computer is used for drawing a frequency domain curve according to preset configuration and the calibrated real-time frequency domain signal amplitude so as to acquire real-time frequency domain data of the vehicle from the frequency domain curve. According to the invention, the frequency domain data is calibrated according to the preset standard, and the frequency domain curve is formed on the upper computer according to the same standard, so that the calculation amount is reduced, the test efficiency is improved, and the real-time acquisition of the frequency domain data can be realized.

Description

technical field [0001] The invention relates to the field of vehicle testing, in particular to a measurement system for vehicle magnetic field frequency domain data. Background technique [0002] Since the human body is exposed to a certain electromagnetic field environment for a long time, regarding whether its health is affected by the environment, the International Non-Ionizing Radiation Protection Organization (ICNIRP) has many researches and environmental limit regulations on it to minimize or avoid unintended Electromagnetic influence to protect public personal safety. As we all know, an electromagnetic field environment will also be formed when the vehicle is running, so it is necessary to measure the intensity of the electromagnetic field environment when the vehicle is in use before leaving the factory. At present, the main measurement method is to read the time-domain data of the electromagnetic field generated by the vehicle through an oscilloscope, and then perf...
