CSM Continuous Measurement and Logging

English | 中文

Accomplish application of Continuous Measurement and Logging with CSM. It's much more simple, intuitive and graceful.

Reusable Modules

Logging Module : Logging 1D Waveform Data to tdms file

API	Description	Parameter
API: Update Settings	Config API	Full path of data folder (Type: Plain String)
API: Start	Start logging. Create the tdms file in data folder with time-based file name.	N/A
API: Log	Log data to tdms file.	1D Waveform array. (Type: MassData Arguments)
API: Stop	Stop logging.	N/A

Example: (Suppose module name is "Logging")

API: Update Settings >> c:\_data -> Logging
API: Log >> MassData-Start:89012,Size:1156 -> Logging
API: Start -> Logging
API: Stop -> Logging

Acquisition Module : Generate Sine/Square Simulated signal data

API	Description	Parameter
API: Update Settings	Config API	Cluster:{HW(String),Signal Type(Enum)} (Type: HexStr)
API: Update Settings v2.0	Config API	HW:(string);Signal Type:(Sine Wave | Square with Noise) (Type: API String)
API: Start	Start data generation every 200ms.	N/A
API: Stop	Stop data generation.	N/A

Status	Description	Parameter
Acquired Waveform	Simulated Data.	1D Waveform array. (Type: MassData Arguments)

Example: (Suppose module name is "Acquisition")

API: Start -> Acquisition
API: Stop -> Acquisition
//With CSM-API-String-Arguments-Support, update 'Signal Type' with plain text description
API: Update Settings v2.0 >> Signal Type:Sine Wave -> Acquisition

Algorithm Module : Algorithm on waveform data

API	Description	Parameter
API: FFT(Peak)	Analyze waveform with FFT(peak) method	1D Waveform array. (Type: MassData Arguments)
API: FFT(RMS)	Analyze waveform with FFT(RMS) method	HW:(string);Signal Type:(Sine Wave | 1D Waveform array. (Type: MassData Arguments)
API: Power Spectrum	Get Power Spectrum of Waveform	1D Waveform array. (Type: MassData Arguments)

Status	Description	Parameter
FFT(Peak)	FFT(peak) spectrum Data.	1D Waveform array. (Type: MassData Arguments)
FFT(RMS)	FFT(RMS) spectrum Data.	1D Waveform array. (Type: MassData Arguments)
Power Spectrum	Power Spectrum Data.	1D Waveform array. (Type: MassData Arguments)

Continuous Measurement and Logging Application

Logging Module and Acquisition Module don't know each other at all. User interface module is needed for Continuous Measurement and Logging application. To make it sample(and easy to compare with workers), UI Module is also acting as the controller of the application.

When you need to use real hardware for data acquisition, create another CSM module for your hardware with the same API/Status and replace the Acquisition Module in UI module.

UI Module

Create UI, which is similar as Workers Continuous Measurement and Logging Example

Create Block Diagram with CSM Template. Drop Logging Module and Acquisition Module as submodules.

stateDiagram-v2
direction LR
Acquisition --> Algorithm : "Acquired Waveform >> Power Spectrum"
Acquisition --> Algorithm : Acquired Waveform >> FFT(RMS)
Acquisition --> Logging  : "Acquired Waveform >> API：Log"
Acquisition --> UI : "Acquired Waveform >> UI：Update Waveform"
Algorithm --> UI : "FFT(RMS) >> UI：Update FFT"
Algorithm --> UI : "Power Spectrum >> UI：Update Power Spectrum"

Loading

Start-Up Process (Macro: Initialize)

Initialize data and UI. Load configuration from xml file and send config to submodules. Register "Acquired Waveform" status of "Acquisition" to "UI: Update Waveforms" state of "UI". When "Acquired Waveform" status occurs, "UI" will go to "UI: Update Waveforms" automatically.

Exit Process (Macro: Exit)

Stop submodules and UI module itself then.

Start Process (Macro: Start)

Update UI and trigger submodule to work with start message. Register "Acquired Waveform" status of "Acquisition" to "API: Log" state of "Logging". When "Acquired Waveform" status occurs, "logging" will go to "API: Log" automatically.

Stop Process (Macro: Stop)

Update UI and stop submodules. Unregister "Acquired Waveform" status of "Acquisition".
