5.2 Workflow
The workflow of this signal digital processor follows the core logic of "signal acquisition conditioning filtering operation processing data output", and the specific steps are as follows:
1. Signal acquisition: The raw signals (analog/digital) output by external sensors (such as temperature sensors and pressure transmitters) enter the signal input module through input terminals to complete the initial signal connection.
2. Signal conditioning and filtering: The original signal is amplified by a programmable gain amplifier (PGA) and converted from analog to digital by an ADC (analog-to-digital converter); Meanwhile, digital filtering algorithms suppress noise and interference in the signal, purifying the effective signal.
3. Digital operation and processing: The core processing unit calls preset algorithms (such as arithmetic operation, logical judgment, PID operation) to process the purified digital signal, generate control instructions or monitoring data.
4. Data output and interaction: The processed results are output in two ways: one is to convert them into analog or digital signals through the signal output module to drive the actuator action; The second is to upload data to the upper control system through the communication module, achieving data sharing and remote monitoring.
5. Status monitoring and diagnosis: Throughout the entire working process, the diagnostic module monitors the real-time operation status of each module and the integrity of input and output signals. If a fault is detected (such as signal over range or communication interruption), it immediately triggers a fault alarm and records a log, while also prompting through LED indicator lights.
