For measuring the change of the Diameter growth of trunk half；The data acquisition unit is used in collecting sensor the change of the trunk radius measured
Information；The micro energy lose processor is used to calculate the trunk radius change information that data acquisition unit is collected by analyzing, in real time
Control measurement, the transmission and early warning of metrical information of tree breast-height diameter automatic measurement system；The wireless transport module is used for number
The change information data of the trunk radius gathered according to collector are sent to distal end with wireless mode and taken by wireless transport module
Business device or hand-held monitoring equipment.
The resistive band uses steel alloy.
The cassette tape is elastic card band, to be stretched with arboreal growth.
Tree breast-height diameter automatic measuring instrument is in use, bandage is looped around on trunk, using the buckle and cassette tape on bandage both sides
Bandage is fixed on trunk by cooperation；The tail end of fixed wire is encapsulated into spring pressure box again, now tree breast-height diameter is surveyed automatically
Amount instrument installs；With the growth of trees, trees girth is consequently increased, fixed-node wire and active junction point wire all by
Elongate, now, the resistance between fixed-node and active junction point also increases, and sensor tests change in resistance by electrical bridge principle,
Changing value is sent to data acquisition unit, and then is sent in micro energy lose processor by the way that resistance strip length is calculated, then is changed
It is counted as the diameter of tree, you can obtain monitored results.
Advantages of the present invention：Tree breast-height diameter automatic measuring instrument is also increased as using resistive band with the growth girth of tree,
The resistance of corresponding point-to-point transmission also increased rule, tests change in resistance, then by the way that resistance is calculated by electrical bridge principle
Strip length is converted into the diameter of tree；After being arranged on first on fixed normal wood, automatic detection can be realized, survey measurements is accurate,
It is adapted to the measurement of the long-term unsupervised trees in field, it is not necessary to look for normal wood every time, it is not necessary to which survey crew enters field, effect
Rate is high, and security is good.
