Study On The Remote Monitoring System Of Stumpage Diameter Growth And Environmental Information

The stumpage diameter is the main measuring factor of the forestry measurements. However, the current measurement mode can not meet real-time and continuous measurement. The study established a kind of system---remote monitoring system of stumpage diameter growth and environmental information which can realize the real-time and continuous measurement. This system is set up by combining the self designed Tree Diameter Automatic Measuring Device, several environmental sensors and the mature wireless sensor network. At the same time, node protective equipment and solar power application were designed for every node, and remote monitoring interface was developed for the whole system. This remote monitoring system has some features such as low power, responsive, precise measuring, high reliability,"green" power supply, efc. Moreover, the measurement accuracy of the stumpage diameter can reach5u m.There are two innovative points in the thesis:(1) Established the remote monitoring system of stumpage diameter growth and environmental information, enabled the accurate remote monitoring of standing tree growth and woodland environmental information in real time to be a reality;(2) Developed a kind of tree diameter (growth) automatic measuring device and related mathematical model for coverting the output from to the value of tree diameter (applied for a patent).
