Abstract: The power consumption and computing power of industrial control equipment face high latency and decreased service quality when compiling complex Programmable Logic Controllers(PLC)software.As a result,industrial software applications are face with challenges.To address these challenges,an efficient compilation method for industrial software oriented towards PLC especially IEC61131-3 was proposed.By modeling under industrial environment that supported end-edge collaboration,the relevant computational properties of the compilation task were analyzed with intelligent methods.Then a game model with multiple compilation tasks was constructed,and an algorithm was designed for solution.In addition,to improve the on-time compilation rate of the system,the order in which each compilation task obtains computing resources was determined by priority sorting,ensuring that the on-time rate was optimized while reducing the overall compilation time,reducing compilation delays and maintaining the service quality of industrial equipment.The experimental results showed that the proposed method effectively utilized the computing power provided by edge servers,avoided a large number of timeouts in compilation tasks,and its performance was fully validated in the scenario of end-edge collaboration.

摘要： 针对工业场景下端侧可编程逻辑控制器设备集群进行复杂程序多编译任务时面临的高延迟和服务质量下降等问题,提出一种面向可编程逻辑控制器设备集群的工业软件端边协同高效编译方法。在支持端边协同的工业环境下建模,通过智能化方法解析编译任务的相关计算属性,构建一个多编译任务的博弈模型并设计了算法进行求解。为了提高系统的编译准时率,以优先级排序的方式决定每个编译任务获取计算资源的顺序,保证在降低整体编译时间的同时优化准时率,降低编译延迟,维持工业设备的服务质量。实验结果表明,该方法有效利用了边缘服务器提供的计算能力,避免了编译任务大量超时,其性能在端边协同的场景下得到了充分验证。
