Measuring system of high polymers' pyromagnetic effect

摘要

The measurement system is the main equipment of the project. Based on the characteristic of experiment system, a sensor array is designed, and used to continually acquire the global magnetic field. A scientific scheme is developed to get the signal processing and temperature compensation for nondirective weak magnetic field. The software of sampling control system is given,which is complied using C language in Labwindows/CVl. Taking computer as main engine, the system can acquire the nondirective weak magnetic field automatically and continuously use the sensor array, the change of magnetic field can be shown in real-time and intuitively.
