Description

Simulate vibrations waveform data. Provide sample size, measurement duration and frequencies of the base waveforms.

Environment Variables

Module Specific

The following module configurations can be provided in a data service designer section on weeve platform:

Name	Environment Variables	type	Description
Sample Size	SAMPLE_SIZE	integer	Number of samples taken per second, sample rate of 1024 means that 1024 values of the signal are recorded in one second.
Measurement Duration	MEASUREMENT_DURATION	integer	How long (in seconds) the measurement period lasts and batches the data.
Main Frequency	MAIN_FREQUENCY	float	Frequency of the main waveform (Hz).
Main Magnitude	MAIN_MAGNITUDE	float	Magnitude of the main waveform.
Vibration Frequency	VIBRATION_FREQUENCY	float	Frequency of the vibration waveform (Hz).
Vibration Magnitude	VIBRATION_MAGNITUDE	float	Magnitude of the vibration waveform.
Vibration Probability	VIBRATION_PROBABILITY	float	Probability that the signal will start a vibration anomaly at this frequency during any time step.
Continue Probability	CONTINUE_PROBABILITY	float	Probability that the signal will continue emitting noise at this frequency during any following timestep.
Noise Standard Deviation	NOISE_STANDARD_DEVIATION	float	Standard deviation of the noise of the composite signal, randomly generated from the normal distribution.
Output Label	OUTPUT_LABEL	string	The output label at which data is dispatched.

Set by the weeve Agent on the edge-node

Other features required for establishing the inter-container communication between modules in a data service are set by weeve agent.

Environment Variables	type	Description
MODULE_NAME	string	Name of the module
MODULE_TYPE	string	Type of the module (INGRESS, PROCESS, EGRESS)
EGRESS_URLS	string	HTTP ReST endpoint for the next module

Dependencies

requests
numpy

Input

This module does not take any input.

Output

Output of this module is bytes object containing compressed (LZMA compression) array of data points of a simulated waveform.
