The GSM-Batcorder Box Set is designed for places without enegr supply and contains all the advantages of the GSM-Batcorder with the following accessories:
The GSM Batcorder
The GSM battery is based on the succesfull batcorder 3.1 and includes all the features of the wind turbine extension control module. Thus it includes SMS messaging as well as microphone testing. You'll get established and well proven technology in a new design. In addition it features an USB connection that allows access while the batcorder is not in scanning mode. Connect the mobile phone with a computer and download data automatically or remotely.
Utilizing an USB connector the mobile phone can be connected to any computer. We have established a simple script-based backup system running on a Raspberry Pi. This automatically backups newly recorded bat sounds on an external memory connected to the Raspberry Pi using rsync. Practically that is a USB memory stick with capacities of 128 GB or more. If the Raspberry is connected to the internet a status message is sent as well as information about the successful backup and backup available space.
For remote access the Raspberry Pi must be connected to the internet (fixed IP at the router) and the turbine internet router needs to be forwarded to the Raspberry for SSH. That has been established by the turbine owner. If setup correctly you can connect via SFTP and download recordings to your office.
Wind energy plays a crucial role in sustainable energy generation. In the planning of the location of the conflict of wind energy and mortality is to be considered. In Germany a standardized monitoring concept was worked on at universities Hanover and Erlangen-Nuernberg. In this study up to 90 batcorders were installed in wind turbine nacelles (alltogether 13000 nights of sampling).
Supplied with the extension is a special plastic disc in which the microphone is embedded in (boundary microphone). This disc was specifically developed for the batcorder. Its properties are as similar to the disc used in the above mentioned project. Thus, data collected with the batcorder extension can be compared to the project data if the bat- ton uses the same settings. The disc is inserted directly into the gondola through a drill hole with a diameter of 10cm.
