可重构控制系统框架的设计与实现

Design and implement of reconfigurable control system frame

针对控制系统存在的开发周期长、开放性差、操作复杂、设备利用率低等问题,将可重构技术的思想理论应用到机电控制系统的开发中,提出了一种模块化静态可重构的控制系统设计框架,在此基础上定义了一组行为规则库,并详细说明了上位机任务解析方法和下位机任务耦合机制;最后,基于三菱FX系列编程口通信协议,利用可视化编程软件和可编程控制器对该框架进行了可行性和有效性的验证。实验结果表明,该系统框架的设计方法可以实现系统输出逻辑的快速重组,降低操作复杂性,有效提高机电设备的开发效率和利用率,增强了系统的柔性。

Aiming at problems in control system, such as the long development cycle, poor openness, complex operation, low utilization ratio and the like, the idea about reconfigurable technology was applied to develop the electromechanical control system, a kind of modularized and static reconfigurable structure of control system was presented. On this basis, a group for action rule warehouse was defined, the analytic method of master computer and coupling mechanism of the slave computer were specified. At last, based on the programming port communication protocols for Mitsubishi FX serials, its feasibility and effectiveness were validated with the visual programming software and programmable logical controller. The result shows that this designing idea of system structure can make the rapid reconfiguration of the system＇s outputting logic, decrease the operation complexity, improve the development effectiveness and utilization of the electromechanical equipment, and enhance the system＇s flexibility.
