Introduction
Song Meter® with Analysis and Remote Transfer, or SMART™, is a multi-channel, ultrasonic audio recording and analysis platform from Wildlife Acoustics®.
Getting Started
The first time you use a SMART System, we recommend setting it up in an accessible location, such as an office. This will make it easier to configure the SMART and perform any necessary troubleshooting.
Microphone Settings and Schedules
Each microphone connected to a SMART Controller can have its own Setting Profile and Schedule Profile. These profiles determine when the microphone is active; the settings it uses to detect, record, and analyze bat echolocations; and set the scheduling of microphone sensitivity testing and moisture clearing.
SMART Controller Configuration
Before you deploy the SMART System, you should configure basic system and network settings. These include login credentials, date, location, and network configuration settings.
Data Management
The SMART System stores recordings and logs on its internal drive initially, and it can periodically transfer new data to a USB or networked storage drive.
Installing SMART
Installing the SMART System on a wind turbine, meteorological tower, or similar structure requires careful planning. Proper connectivity, grounding, and microphone placement will help ensure a successful deployment.
Bat Activity Alarms and Control System Integration
The SMART System can integrate with a windfarm SCADA network or similar control system to perform acoustically triggered curtailment (ATC). You can define custom alarms that detect bat activity based on custom-defined parameters. When these alarms trigger, you can send control signals to other devices on a control system to trigger turbine shutdowns.

smart-daemon

daemon process to interface with SMART devices

Synopsis


            smart-daemon [--force] [-i
               ifname ]

Description

Binds to the specified Ethernet interface (or the first suitable interface if ifname is not specified) and begins communication with SMART devices over Ethernet. A control socket is created to interface between the daemon and user processes by means of the libSMART shared library.

The SMART daemon must be run as root. A valid license is required to run the SMART daemon and to use the libSMART libraries.

Options

--force: is used to force the SMART daemon to run even if a PID file already exists.
-i interface: specifies the Ethernet device interface to use. Otherwise, the first suitable interface found is used automatically.

Files

/var/run/smart/smart_pid: A file containing the process id of the currently running SMART daemon.
/var/run/smart/smart_ctl: A UNIX socket used by libSMART to communicate with the SMART dameon.
/usr/local/share/smart/smart.lic: A license file required for using the SMART daemon and libSMART.
