- Abstract
To obtain the field fuel moisture content ( FMC) for forest fire prediction, a FMC monitoring system is designed to obtain FMC in the field automatically and persistently. The FMC monitoring system is powered by solar-powered device, single chip microcomputer is used to control the load cell to obtain the fuel quality, data is transmitted to computer terminal by Beidou module or mobile phone terminal by Bluetooth, FMC can be obtained by built-in algorithm in terminal. The FMC monitoring system has been tested in extreme environment, long-term monitoring and cross regional verification test, and performed well in long-term monitoring with R² of 0. 98 and maximum MAE of 10. 8% in cross regional verification. Compared with the manual measurement of FMC, FMC monitoring system has great advantages in field FMC acquisition, which can save manpower and reduce error, and improve the accuracy of forest fire prediction effectively.
