Start of the project “Development of an autonomous sound emission sensor node for the Condition monitoring of standing trees (TreeMon)
as part of the Digital GreenTech funding measure – environmental technology meets digitalization FKZ: 02WDG1698A
It is known from previous studies that various microacoustic sound emissions occur within standing trees in both the audible and ultrasonic range. They allow conclusions to be drawn about the condition of the tree, its traffic safety, drought stress and sap flow anomalies, and possible pest or disease infestation.
As part of the project, the demonstrator of a wireless sound emission sensor node is to be developed, which is attached to the trunk of the tree and can record micro-acoustic sound emissions over a longer period of time and evaluate them independently or with the help of a central computer based on machine learning. In addition to temperature, humidity and wind data, dendrological and digital optical parameters of the tree should also be recorded in order to obtain a correlation with the acoustic measurement data at different times. The digital measuring system should
- detect and classify significant damage and illnesses that can impair road safety at an early stage,
- propose timely measures to prevent the trees from dying or being damaged and to allow more stable and better yields in fruit growing,
- examine the effectiveness of long-term measures in forestry (e.g. cultivation of mixed forests or non-endemic tree species) and, if necessary, serve as a basis for their adaptation and change.
