Design And Implementation Of Embedded System Based Portable Electromagnetic Radiation Meter

The human survival and life can not do without certain electromagnetic environment,but if the electromagnetic radiation around more than quantitative, the human body formthreats or cause damage. Different frequency electromagnetic field has the effects ofdifferent body. Along with the progress of science and technology and the rapiddevelopment of social economy, all kinds of electronic, electric power equipment andfacilities appear in People’s Daily life and work. However, subsequent electromagneticradiation pollution problem is increasingly serious.This topic is based on the core processor S3C2440Embedded hardware platform andLinux operating system, through the Qt/Embedded interface development tools design ofelectromagnetic radiometer. The radiometer cans not only real-time display measurementdata, but also can store history data in data management software to analysis query. In thispaper based on the analysis of the architecture of the system, expatiates theelectromagnetic radiometer hardware platform; Embedded Linux operating system set upmainly includes the BootLoader transplantation, Linux Kernel cropping and transplantation,the root file system customization, and write the embedded Linux system of relatedhardware driver.The radiometer can carry, high measurement accuracy, and compared with thetraditional electromagnetic radiometer is friendlier interface, curve analysis, historical databackup inquires the advantages, such as electromagnetic radiation environmental changesprovide reliable basis. So it around the detecting electromagnetic radiation environmentalchange and risk is of great significance.
