【摘要】 陶瓷辊道窑烧成是一种大型、复杂和连续的工业生产过程，具有多变量、强耦合的特点。在研究分析影响烧成质量的五个过程——制品变化过程、物料运动过程、燃烧过程、传热过程和气体流通过程的基础上，提取了四个主要因素——温度、压力、气氛和传动。并对它们之间复杂的耦合关系做了定性分析，进而得到了辊道窑烧成过程的综合影响模型。根据辊道窑烧成过程的综合影响模型，相邻检测点量测值之间存在冗余性关系。本文针对这种关系提出利用相邻检测点的数据，采用基于D-S证据理论的自适应加权算法，对检测点量测值进行估计，以增强它的准确性和可靠性。所研究的算法兼顾计算复杂性和估计精度两个指标，具有一定的实用性。最后，本文给出了基于CAN总线的辊道窑网络化控制系统整体架构，同时对它的通信系统进行了模块化设计，在CAN应用层上开发了节点的数据索取和支付功能，通过节点之间信息共享的方式，不仅为量测值估计算法的实现提供了硬件基础，也为CAN总线提供了一种新的点对点通信模式。更多还原

【Abstract】 The ce ramic production firing of roller kiln is a large scale, complex and continuity industry manufacture process, which has multi-variable and strongly coupled character. There are five processes in it, which are product physic-chemic transformations, material moving, combustion, heat transfer and gas flow processes. In these processes, the relations among four factors have been studied, which are temperature, pressure, atomosphere and transmission velocity. Then a synthesis model of the roller kiln process has been founded.As measuring values of different detecting nodes in roller kiln have redundancy relationship according to the model, an adaptive weighted arithmetic based on D-S evidence theory has been brought forward to estimate a more exact and reliable value. It is practicable by giving attentions to both of calculation complexity and estimation precision.Finally, a networked control system structure of roller kiln has been designed with CAN technology. Then its communication functions have been decompossed in several blocks. As fiame requesting and offering functions are developed in the application layer of CAN, information sharing fuction has been implemented among the nodes, which provides the base to realize the previously arithmetic and a new model of point to point communication in CAN.更多还原
