摘要
在嵌入式技术的支持下,设计一种小型PLC智能控制模块。通过嵌入式的方式改装PLC的内部结构和接口。智能分配PLC内存空间,设计合理的用户控制任务调度算法。从开关量和数字量两个方面,实现小型PLC智能控制模块任务调度。验证实验表明:与传统控制模块相比,设计模块的开关量控制成功率提高了6.38%,数字量控制误差降低了2.8,且吞吐量得到明显提升。
This paper designs a miniaturized PLC intelligent control module with the support of embedded technology. The internal structure and interface of PLC are refitted through embedded mode. PLC memory space is intelligently allocated and reasonable user control task scheduling algorithm is designed. The task scheduling of small PLC intelligent control module is realized from two aspects of switching value and digital value. The verification experiments indicate that the switching value control success rate of the designed module is increased by 6.38%, the digital value control error is reduced by 2.8, and the throughput is significantly improved in comparison with the traditional control module.
