基于Plant Simulation的产线车辆调度问题
Production Line Vehicle Scheduling Problem Based on Plant Simulation
随着“中国制造2025计划”的进行,军工工业要推行产线无人化,而自动引导车(automated guided vehicle, AGV)作为全自动化生产线的主要物流载体,其调度的优劣直接决定了整个产线的产能和效率。由于军工场所对于安全性的要求,无法采用无线通信等手段,只能采用点对点的光通讯方式,这也使得AGV通讯的实时性变差。基于Plant Simulation软件,建立了仿真系统模型,打通了该物流仿真软件与现场控制器的实时数据交互通道,实现了仿真系统与现实同步运行,完成了物流仿真软件与现场控制器的无缝连接,有效地解决了军工工业没有无线造成AGV调度实时性差的难题。实验证明,这种方法有效地简化了调度系统的编写难度,并使系统整体的实时性能提高了0.058 s。与传统方法相比,编写时间缩短了9.7倍,调试时间更缩短了22倍。为军工产线实现全自动化奠定基础,并为在危险场所使用脉动生产线提供技术支持。
With China's Manufacturing 2025 Plan, the military industry to implement the unmanned production line, and AGV(automated guided vehicle) as a fully automated production line of the main logistics carrier, the scheduling of its strengths and weaknesses directly determines the capacity and efficiency of the entire production line. Due to the security requirements of military industrial places, wireless communication and other means cannot be used, and only point-to-point optical communication can be used, which also worsens the real-time communication of AGVs. Based on Plant Simulation software, a simulation system model was established, the real-time data interaction channel between the logistics simulation software and the field controller was opened, the synchronous operation of the simulation system and the reality was realized, and the seamless connection between the logistics simulation software and the field controller was completed, which effectively solves the difficult problem of poor real-time AGV scheduling caused by the lack of wireless power in the military industry. Experiments have proven that this method effectively simplifies the difficulty of writing the scheduling system and improves the overall real-time performance of the system by 0.058 seconds. Compared with the traditional method, the writing time is shortened by 9.7 times, and the debugging time is even shorter by 22 times. This study lays the foundation for the realization of full automation of military production lines and provides technical support for the use of pulsation production lines in hazardous places.
