Accelerometer Manager Properties - Accelerometer definition

If you select the module in the Tree view after you have added the module, the categories and settings of this tab appear in the Properties view.

The additional Accelerometer Manager properties presents you with the configuration properties of the accelerometers feeding data into the Accelerometer Manager module.

Important Tip - Trimble recommends to not set up the accelerometer properties immediately after you have added the module. When the connection to the RTPD service is established, information on available accelerometer data streams will arrive (this may take a while) and will be automatically selectable for the accelerometer properties.

Accelerometer <#> category

The settings of this category specify an accelerometer hardware and data streams. You can specify several accelerometers. When you have filled in an Accelerometer ID property (and set the focus elsewhere), a new empty Accelerometer <#> category of settings with a new Accelerometer ID property is created.

Tip - For deleting an accelerometer entry from the list of entries, set the focus into the Accelerometer ID value field and click the Button Delete button.

Accelerometer ID: Specifies the accelerometer by the ID of the Data Acquisition System (DAS) unit that provides the data, the ID of the accelerometer data stream and the channel IDs for X, Y, and Z directions. By default, the property is empty. For specifying the accelerometer ID, set the focus into the value field and click the browse button. The Accelerometer Sensor Information dialog appears. Use it to view or edit accelerometer data. As soon as the accelerometer data stream is identified, additional properties appear.

Accelerometer name: Use this property to assign an arbitrary name to this accelerometer data set. A good idea for the accelerometer name is, for example, the serial number of the accelerometer hardware device.

Free field accelerometer: A possible setup of accelerometers takes reference accelerations of the surrounding area into account: It corrects the measured accelerations at the monitored structure or site by those derived from an accelerometer device that is installed off-site. This off-site accelerometer, therefore, acts as a free field reference.

By default, no free field reference accelerometer is selected (None) and no free field accelerometer available for selection. Only, if you have already defined two accelerometer sensors using the Accelerometer Sensor Information dialog, these sensors will be available for selection.

Tip - For using reference accelerometer corrections, first provide the accelerometer sensor information for the free field accelerometer(s), then add the accelerometer sensor(s) whose data will be corrected.

Alarming category

These properties are used to define the parameters applicable to alarm conditions.

No data interval [hh:mm:ss]: This property pertains to the No data alarm, which is triggered if no data is arriving for the specified period. Make sure that this interval is greater than the value set for the Realtime buffer property of the Incoming connection.

Filter Settings category

These properties are used to define the parameters applicable to outlier filtering.

Threshold [g]: This property specifies a threshold for accelerations given in the gravity acceleration unit g: 1 g » 9.81 m/s². Acceleration values which exceed the threshold are not used for further calculation. The value must be positive and not zero, decimals are allowed.

RTPD Settings category

These properties are used to define the settings for extracting the filtered data to be used with post-processing.

RTPD archive folder: Specifies the base folder of the RTPD archive. Using the Trimble 4D Control Web Analysis view the (high frequency) data contained in this folder may be displayed. However, the reduced data are stored in the Monitoring DB.
