Operation Verification, Fault Diagnosis, and Testing Using Pulse Generators

Testing with pulse generators is widely utilized for signal input simulation in marine remote control systems, as well as for verifying the operation of engines, motors, propellers, and more.
It simplifies operational checks and troubleshooting, making it highly effective for routine maintenance and anomaly diagnosis.

Overview

By inputting simulated dummy signals from a pulse generator into remote control systems, engines, or motors, operators can thoroughly verify system behavior.
Simultaneously, data collection can be performed using various sensors alongside measuring instruments for speed, temperature, current, voltage, resistance, torque, and more.

What You Can Achieve with This Solution

Pulse Generators

Engine and Motor Inspections
Input dummy signals into remote controllers using a pulse generator.
By replicating control lever or throttle positions, you can verify that engines, motors, and control units respond correctly.

Drivetrain and Propeller Operation Verification
Apply pulse signals to confirm if engine throttle opening or propeller pitch settings are accurately reflected.
Eliminates the need to start the actual engine; by using the generator's phase A/B signals as dummy inputs, you can safely verify forward/reverse rotation of screws and propellers.

Anomaly Diagnosis & Troubleshooting
When a fault occurs within remote control systems, input simulated signals to pinpoint exactly at which stage the error triggers.
Analyze root causes behind communication dropouts, signal latency, or malfunctions.

Durability & Stress Testing
Perform repetitive pulse inputs to evaluate long-term structural reliability and durability under continuous operations.
Vary specific frequencies to inspect the impacts of anomalous operations or degradation over time.
