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.
- Alarms
  As the SMART System is recording and analyzing, it can trigger alarms when the characteristics of the bat call meet certain parameters. Raised alarms can be sent to a control system in order to shut down or slow a turbine.
- Control System Integration
  The SMART System provides several means through which other devices can retrieve information about detected bat activity in real time. This information can be used to inform automatic wind turbine curtailment or similar control decisions.
  - Control System Integration with OPC UA
    OPC Unified Architecture (OPC UA) is a machine-to-machine communication protocol used for industrial automation developed by the OPC Foundation. The SMART Controller OPC UA interface provides a secure mechanism for retrieving status information, system updates and alarm notifications from a SMART device.
  - Control System Integration over Modbus
    One method for integrating a SMART System with a SCADA system or similar control system is using the Modbus protocol. Other Modbus-compatible devices on the network can poll the SMART System for information about the system's status and the status of the SMART System's bat activity alarms.
    - Configure Modbus TCP or Modbus RTU
      Before Modbus clients on a SCADA network or other control system can poll the SMART's Modbus registers, and before a OPC Unified Architecture (OPC UA) client can interact with the SMART's OPC UA server, you must enable Modbus functionality in the SMART Control Panel.
    - Addressable Modbus Registers
      You can use Modbus to access information about the SMART System's status and its bat activity alarms. You can also alter some parameters of bat activity alarms using Modbus messages.
  - Control System Integration Using the Digital I/O Pins
    The SMART Controller features a block of assignable, Digital I/O (DIO) pins. You can control these pins with a simple script to signal the states of up to four alarms in response to detected bat activity.
  - Serial Output
    The SMART System can output system status information and pass-level measurements of bat call parameters via its two serial ports.

Control System Integration over Modbus

One method for integrating a SMART System with a SCADA system or similar control system is using the Modbus protocol. Other Modbus-compatible devices on the network can poll the SMART System for information about the system's status and the status of the SMART System's bat activity alarms.

SMART supports Modbus TCP/IP over ethernet and Wi-Fi and Modbus RTU via either of its two DB-9 serial ports, which can be configured for RS-232, RS-422, or RS-485. When Modbus is active, the SMART System acts as a Modbus server. Modbus clients on the same network can poll the SMART to retrieve the status of any of SMART's Modbus registers.
