System architecture and working principle

Core component modules

· Vibration sensing module: composed of high-precision vibration sensors and signal conditioning adapters, responsible for collecting and preprocessing vibration signals

· Acquisition and storage module: integrated 16 bit A/D converter and FLASH memory to ensure data acquisition accuracy and local storage capacity

· Microprocessor module: responsible for data processing, system control, and communication protocol management

· Wireless networking module: supports WIFI wireless transmission, with an effective coverage range of up to 2000 meters

· Self calibration module: provides remote calibration function to ensure the accuracy of long-term monitoring

· Power supply module: provides stable power support for the entire system

Data processing flow

After the vibration signal is collected by the sensor, it is preprocessed by the signal conditioning adapter and then enters the A/D converter to complete the analog-to-digital conversion. The digital signal is analyzed and processed by a microprocessor and stored in FLASH memory. At the same time, it is uploaded to the monitoring center through a wireless module based on preset thresholds and time intervals.
