Electric controller for measuring diameter of tree

Abstract

The invention discloses an electric controller for measuring the diameter of a tree. The controller includes a master control unit, the input of the master control unit is connected with a first counter and a second counter; the master control unit is bidirectionally connected with a communication unit, the input of the communication unit is connected with a first power supply unit, the input of the first power supply unit is connected with a second power supply unit, the output of the second power supply unit is connected with the master control unit, and the input of the second power supplyunit is connected with a power supply. The master control unit can record the growth condition of the tree according to the signal sent by the first counter and monitor whether the electric controlleroperates normally or not according to the signal sent by the second counter. Circuit components are few, power consumption of each unit is low, and long-time endurance can be provided.

Description

technical field [0001] The invention relates to the field of tree monitoring, in particular to an electric controller for tree diameter measurement. Background technique [0002] In the survey of forest resources, the diameter is an important stand measurement data, and it is one of the most basic factors reflecting the quality and growth of active wood. Tree diameter naturally shrinks and expands as the trunk moisture changes, and also changes in diameter as the trunk fixes carbon dioxide, causing the tree to grow. Long-term online monitoring of tree diameter is helpful to understand the short-term diameter changes, long-term growth and growth rate changes of trees, which is of great significance for forest cultivation and forest stock investigation. [0003] The most primitive and direct way to measure the diameter of trees is to measure manually with a girth. This traditional tree diameter measurement is mainly achieved by using a diameter girth and a tree diameter calip...

Problems solved by technology

[0003] The most primitive and direct way to measure the diameter of trees is to measure manually with a girth. This traditional tree diameter measurement is mainly achieved by using a diameter girth and a tree diameter caliper. These two tools are also manual readings, and there are artificial error, time-consuming and labor-intensive, and low efficiency. On the other hand, this method cannot accurately measure the change in diameter, and it is not convenient to monitor the diameter of trees online.
