Real-Time Control with Standard C! Microsecond Hard Real-Time, Rapid Solution Deployment

2026-05-29(5)Browse

This article introduces the AsMotion motion control solution, which leverages a hard real-time architecture based on standard C language and X86 hardware to address the core challenges in high-end precision equipment development—such as low stability, high development barriers, and long cycles associated with traditional PLC, DSP/FPGA, and control card solutions. By deploying an exclusive physical core for deterministic real-time scheduling, AsMotion achieves control cycles as low as 100μs, stable EtherCAT synchronization at 250μs, fully synchronized control for up to 128 axes, and microsecond-level image transmission latency. The solution emphasizes rapid integration on universal hardware, open development in Visual Studio, and seamless support for real-time vision algorithms (Halcon/OpenCV). Aimed at applications like winding, dispensing, and mounting, it enables equipment manufacturers to shorten R&D cycles, enhance operational stability, and accelerate process iteration, providing a low-risk, high-performance path for transitioning from PLC to PC-Based control.

In high-end precision equipment manufacturing, motion control directly determines positioning accuracy, operational stability, and mass production consistency. It serves as a critical support for core processes such as winding, dispensing, mounting, and precision alignment. Built on a hard real-time architecture, AsMotion delivers high-precision, high-stability, and rapidly deployable motion control capabilities for high-end equipment, fundamentally ensuring equipment performance and production safety.

 

Industry Pain Points: Architectural Defects and Production Risks of Traditional Solutions

High-end equipment development currently faces common challenges: high difficulty, long cycles, and insufficient stability.

· Traditional PLC solutions have limited logic expression, making complex processes hard to implement efficiently.

· DSP/FPGA solutions involve high development barriers, long debugging cycles, and restricted code size.

· Traditional control cards have limited memory, unable to efficiently deploy complex algorithms.

· Windows system scheduling interference and image transmission latency fluctuations easily cause positioning errors, downtime, and batch defects, leading to production losses and delivery risks.

 

Solution Introduction: Underlying Architecture Reconstruction to Systematically Solve Industry Pain Points

Abandoning closed frameworks and dedicated hardware, AsMotion encapsulates hard real-time control capabilities into standard C language interfaces, enabling engineers to develop real-time tasks in a universal development environment. Based on the X86 architecture, the solution ensures control determinism via an isolated real-time kernel, achieves efficient collaboration through shared memory, and eliminates latency with hardware passthrough interfaces. It fundamentally resolves the core issues of traditional solutions: difficult development, insufficient stability, and weak openness.

 

Architecture Overview: Universal Hardware Deployment, Minimal Integration, and Stable Operation

· Deployment: Real-time kernel runs on an exclusive physical core, securely isolated from the Windows system.

· Hardware Compatibility: Supports standard X86 industrial PCs, no dedicated control cards or emulators required.

· Integration Benefits: Consistent development and runtime environments, easy on-site deployment, low debugging costs.

· Operational Stability: Unaffected by Windows system load fluctuations, supports long-term continuous operation.
