Selection guide: If the data query frequency is less than 1 Hz, REST is preferred; If>10 Hz and complete waveform is required, select Streaming; If the server passively receives, select TCP Socket.
Import custom filtering algorithm
The strength of MCM-204 lies in allowing users to run domain specific algorithms (such as bearing feature frequency extraction, envelope demodulation, etc.) directly at the edge, outputting only results and reducing data volume. The import process is as follows:
Prepare the compilation environment: Download the Linaro ARM cross compilation toolchain (gcc-linaro-6.2.1-2016.11).
Get sample code: Download CustomizadAlgo.zip from the product page, which includes CalRMS (C example) and CalStatistics (C++example).
Compile: Extract the toolchain and examples to the same path, execute the make command in the CalRMS folder, and generate the customAlgo.so dynamic library.
Upload: Upload the. so file through the "Customization Library Upload" option in the "System Settings" section of the web console.
Usage: After logging in again, select "Customization" in the data type and fill in the required parameters (such as window length, filter coefficient, etc.). After applying the task, you can view the output results of the custom algorithm on the data capture page.
Note: Custom algorithms must comply with the specified function interfaces (see example code for details), link to standard libraries during compilation, and ensure that the algorithm execution time does not exceed the set repetition interval.
Key points for maintenance and troubleshooting
7.1 System Reset
Soft reset: Restart through the web console.
Factory reset: Press and hold the reset button for 3 seconds (if "Keep network settings" is enabled, the IP will remain unchanged, and the rest will be restored to default).
7.2 Precautions for Network Cascading
Only supports linear cascading and cannot form loops, otherwise broadcast storms may cause devices to go offline.
After cascading, all devices share the same network segment and use their respective IP or hostname for access.
7.3 Data Persistence Capacity
Only 300MB internal storage, suitable for storing recent historical data. If long-term archiving is required, it is recommended to periodically transfer to the backend database through TCP Socket or REST.
7.4 Power Stability
Despite the wide voltage input, voltage fluctuations or transient spikes may cause system restarts. It is recommended to use a regulated power supply and pay attention to EFT protection (the equipment has passed the IEC 61000-4-4 2kV level).
7.5 Temperature Sensor Installation
The sensor cable is up to 3 meters long and has a measurement range of -50~150 ℃, suitable for temperature measurement on the surface of motor bearing seats or gearboxes. Ensure that the sensor is in close contact with the measured surface.
7.6 Firmware Upgrade Process
Download the firmware file from the official website and upload it to the web console. Do not turn off the power during the upgrade process, and the device will automatically restart after completion.
