3. Working Principle
Power-on Initialization & Self-test: After 5V DC backplane power-on, the module completes full hardware self-inspection, initializes ADC parameters and channel configuration, synchronizes system bus timing, and enters standby acquisition mode.
Field Analog Signal Acquisition: Four independent channels collect -10V~+10V DC field voltage signals, filter common-mode interference and clutter through high-impedance differential circuits, and retain effective signals.
High-speed A/D Conversion: Converts analog voltage signals into standard digital signals via 12-bit high-precision ADC chip, with 1ms single-channel conversion and 4ms full-channel scanning to ensure real-time data.
Data Verification & Filtering: Corrects and smoothes converted digital data through parity check and intelligent filtering algorithm, eliminates abnormal jitter data, and guarantees acquisition accuracy and stability.
Bus Data Upload: Uploads processed process data, channel status and module operating information to the CPU main control unit through Series Six backplane bus for real-time monitoring and closed-loop process adjustment.
Fault Monitoring & Alarm: Detects link faults, data errors and signal over-range abnormalities, triggers LED alarm and fault code upload, isolates faulty channels automatically, and recovers normal operation after troubleshooting.
