The Laser Power Compensation & Monitoring Card Software is a dedicated host configuration and monitoring platform developed for the Laser Power Compensation & Monitoring Card hardware. The two work together as an integrated system—the hardware is responsible for high-precision motion control and signal acquisition, while the software provides an intuitive interface for parameter configuration, real-time data monitoring, and closed-loop algorithm debugging, together forming a complete closed-loop control system solution.

The software operates on a per-channel basis, offering comprehensive parameter configuration and real-time data visualization capabilities. Users can independently set the number of sampling points and acquisition duration for each channel, flexibly adapting to the timing requirements of different test scenarios. The software displays real-time average, maximum, and minimum values of input signals, feedback signals, output signals, and power, while dynamically presenting signal trajectories over time through trend curves, allowing engineers to intuitively evaluate system stability and control precision.

In terms of core control, the software supports one-click switching between open-loop and closed-loop modes, meeting the needs of both debugging and production phases. Users can configure the feedback source (voltage feedback or digital feedback) and finely adjust PID parameters (Proportional P, Integral I, Derivative D) to achieve precise system tuning. Filtering parameters such as input smoothing and feedback smoothing are also provided to effectively suppress signal noise and enhance measurement stability. The correction table function compensates for sensor nonlinearity to ensure full-range measurement accuracy; option settings support flexible adjustment of underlying parameters including gain level, scan cycle, and sampling count to accommodate diverse application scenarios.

The software also integrates comprehensive auxiliary functions: the Read Settings feature quickly retrieves the hardware's current configuration parameters, avoiding redundant input; the Write function saves the current interface parameters to the hardware, ensuring that configurations persist after power cycles. Operating modes include continuous operation or high-level triggering to adapt to automated production line coordination requirements.

In addition, the software interface is clean and intuitive. Taking Channel 1 as an example, key data is displayed at a glance: default sampling points of 1112, acquisition duration of 800ms, input average of 1.00V, feedback average of 5.00V, output average of 9.00V, and power average of 399.93W. The time axis is linearly scaled in milliseconds, allowing users to precisely locate signal states at specific moments, providing reliable data support for troubleshooting and process optimization.
