A method and system for rendering a simulation interface for an energy meter based on ImGui
By adopting the ImGui library and an independent thread-driven interface refresh mechanism, the rendering problems of high-frequency pulse lamps and multi-channel data streams in the energy meter simulation were solved, achieving efficient, zero-latency interface updates and cross-platform deployment, thus improving the performance and maintainability of the simulation system.

AI Technical Summary
The existing GTK+Cairo solution cannot effectively handle the real-time rendering requirements of high-frequency pulse lamps and multi-channel instantaneous data streams in energy meter simulation, resulting in a decrease in rendering frame rate, distortion of visual feedback, and difficulties in cross-platform deployment.
The user interface for the electricity meter is developed using the ImGui library in immediate mode. By using an independent thread and a timer-driven refresh mechanism, combined with data pointer binding, the interface rendering and the business logic of the electricity meter are decoupled, avoiding memory copying and system-level graphical service dependencies.
It enables zero-latency reproduction of high-frequency pulse lamps and instantaneous waveforms on general-purpose computing platforms without GPU acceleration, improving the verification accuracy and cross-platform deployment flexibility of the simulation system, and reducing CPU and memory usage.
