【摘要】：作业车间物流是一个复杂的过程,物料需求具有多种类、高频次、常波动等特点,实现智能物流是提高生产车间效率的有效途径,而物料配送是又是物流的关键,因此及时、准确、高效的物料配送能保证生产过程稳定性和高效性,高效的物料配送系统能减少浪费,降低生产成本。针对当前作业车间物料配送存在的低效率、缺少有效实时加工信息等问题,对物料配送中多个智能配送单元(Unit)系统的调度问题进行研究分析,目标是对作业车间的物料配送过程问题进行优化。本文提出智能配送单元及Units系统的概念,首先对单个智能配送单元的功能模块、数据结构、物理架构等进行研究,针对传统的物料配送系统提出了一种基于多智能配送单元的物料需求实时响应的配送模式,对其中相关关键技术如数字化地图的构建、路径规划、冲突避障等进行设计,并对Unit系统进行软硬件平台的搭建,基于FTPC平台实现对Unit的运行及路径跟踪的控制,得到单Unit的控制运行过程。然后对多Unit协作下车间物料需求响应配送系统进行研究,对其功能模块、数据构成及顶端结构进行设计,再结合黑板原理对多Unit系统的物料任务进行并行处理,实现对系统的多Unit进行全局管理,对车间多Unit的路口通行协作展开研究并进行仿真实验,最后试验了周期控制和感应控制在交叉口交通信号控制中的应用效果,确定车间最佳通行控制模式,实现对多Unit系统的有效管理。
[Abstract]:Job shop logistics is a complex process, with many kinds of material requirement, high frequency, constant fluctuation characteristics, intelligent logistics is an effective way to improve the efficiency of the production workshop, and the material distribution is a key to the logistics, so timely, accurate and efficient distribution of materials to ensure the stability and efficiency of the production process efficient, material distribution system can reduce waste, reduce the production cost. For the low efficiency of the existing job shop material distribution, the problem of the lack of effective real-time information processing, intelligent distribution of multiple unit material distribution (Unit) analysis of scheduling system, the goal is to optimize the material delivery process of job shop problem. The paper puts forward the concept of intelligent distribution unit and the Units system, the first module of single intelligent distribution unit data structure, physical structure and so on, to pass The material distribution system presents a distribution mode of material requirement for real time response intelligent distribution unit based on the related key technologies such as the construction of digital map, path planning, obstacle avoidance conflict of the design, build and hardware platform of Unit system, control operation and path tracing for Unit based on the FTPC platform, control operation process of single Unit. Then the study of multi Unit cooperation workshop material requirements response distribution system, the function module design, data structure and top structure, combined with the principle of blackboard system Unit multi task parallel processing materials, implementation of the system of Unit global management, workshop on multi Unit intersection collaborative research and simulation experiment, finally the test cycle control and induction control control in the intersection traffic signal The application effect is used to determine the best control mode of the workshop, and to realize the effective management of the multi Unit system.
