焦炉尾焦收集手控制系统的研究与设计

摘要

由于国内大部分的焦化厂生产的自动化控制程度较低，很多仍停留在焦车人工

的识别与定位，存在着严重的安全隐患，在自动化控制管理方面非常落后。本论文

就是要在有炼焦装备的基础上,设计一个尾焦自动收集的系统,这样不仅可以提高焦

炭的生产质量,同时也可以提高生产效率,降低工作劳动,也可以带来更好的经济效益。

（1）本文在详细分析尾焦收集机器人手机构的结构和运动规律基础上，把整个

连杆机构转化为四轴运动控制机构，研究其运动规律和控制方法，提出了运动控制

卡的软硬件的总体结构，并按照结构化和模块化的设计方法，确定了系统的各子模

块的功能。

（2）完成了运动控制卡硬件电路部分的设计。在对 DSP 处理器 TMS320VC33

和PCI 总线及一些重要芯片进行深入研究的基础上，实现了运动控制卡的硬件电路

设计，包括 PCI 总线接口电路、编码器信号采集电路、D/A 输出电路、开关量信号

输入输出电路等，整个电路具有元器件少、结构简单以及成本低的特点。

（3）完成了运动控制卡的驱动程序设计。采用了 WinDriver 进行运动控制卡的

驱动程序开发，并详细介绍了驱动程序的开发流程。

（4）完成了系统调试平台的搭建，然后对运动控制卡的控制性能进行了调试，

调试结果表明本文所开发的运动控制卡能够完成很好的控制效果。

Abstract

Because a big part of domestic of coal carbornization factory production control

degree lower, a lot of still stay around the coke pusher is artificial of identify with the

fixed position, this exists serious hidden trouble , falling behind very much in the aspects

of automating control.And this thesis is based on the existing coke making equip of

Xiangtan steel company, to design a automatic collection system of tailing coke .In this

wany ,not only can raise the production quantity of the coke, also can raise the production

efficiency, lower the work labor, can but also bring the better economic benefit.

(1) This paper analysizes the struct and motion rules of tailing collection system in

coke furnace , converts this struct to 4-anxis motion control system ,studies the motion

control rules and ways, the systematic scheme of the Motion Controller is proposed. The

hardware is separated into independent functional modules, and the functions of each

module are designed.

(2) It finishes the hardware design of the motion control card. Based on the study on

the DSP Processor (TMS320VC33) and PCI bus and some important chips, the hardware

is designed, including PCI bus interface circuit, encoder collection circuit, D/A output

circuit, input and output circuit of switch signal. It has the characteristics of less element,

simple structure and low cost.

(3) It finishes the driver design for the motion control card. It uses Windriver for the

driver design, and introduces the driver design step of the motion control card in detail.

(4)It builds the system debug platform, debugs the performance of motion control card. It

is approvd that this card can get the perfect control effects.

The motion control card has advantages of simple structure, low cost, good

application and so on. If improving this motion control card, it might be widely used in the

control field. It has made a good foundation for designing a commercial open control card.

焦炉尾焦收集手控制系统的研究与设计

第一章绪论

1.1 课题的研究背景

焦炭是钢铁工业最重要的工业原料之一。近几年，从总的趋势看，世界的钢铁

产量在增长，焦炭产量也在增长。世界钢、铁、焦炭的增长主要是中国，扣除中国

的增长后，世界其它国家的钢铁产量在增长，但焦炭产量在下降，如下表 1-1 ：

表1-1 世界钢、生铁、焦碳产量对比表

由上表可得 2005 年世界钢产量 110762 万吨，比 2000 年增长 30.5%，其中，中

国占 26.06%，其它国家增长 4.46%；同期世界生铁产量 77935 万吨,增长 35.15%，其

中，中国占 34.23%,其它国家增长 0.92%；而同期的焦炭产量 46078 万吨（预计）增

长33.6%，其中，中国占 35.13%，其他国家减产 1.53%。也就是说，近五年，除了

中国外,世界其他国家钢、铁产量分别增长 4.46%和0.92%,而焦炭产量下降 1.53%。

世界钢、铁、焦炭的增长主要是中国。2004 年中国焦碳产量 20618 万吨，其中出口

1501 万吨，是名副其实的焦碳生产大国，正在向焦碳冶炼强国迈进。

然而，由于我国炼焦行业生产技术和环境治理与世界先进水平存在着较大差距，

焦碳质量有待提高。中国钢铁工业协会副秘书长、中国炼焦协会理事长黄金干近日

指出，由于技术上的差距，焦炭强度不高、灰分偏大，尤其是土焦和小焦产品比重

过大，致使我国的焦炭消耗水平偏高，化工产品回收水平低，焦炭出口在国际市场

上往往是以数量规模和低价格参与竞争。同时，技术含量和附加值不高，造成我国

宝贵资源及能源的极大浪费[1]。近年来，西方一些传统产焦国迫于环保、资源、售价

等压力，其产量和出口量日趋萎缩。面对国际、国内炼焦工业的现状，我国为确保

焦炭产品稳定的出口强势，以及在国际市场上树立起焦炭产品的良好形象，已积极

采取措施，全力展开了对炼焦行业的结构调整和环保治理。

在这里有必要先对焦炭生产的过程做一介绍，炼焦就是将焦煤置于在密闭的焦

炉炉室内经过 14-18 个小时的干馏后得到红焦，随后通过焦炉的移动机车将红焦从炉

室移出送到熄焦室进行熄炭。整个过程中共使用的焦车有推焦车、拦焦车、熄焦车

和装煤车。具体步骤是:当焦炭已经炼成后，推焦车打开炉室机侧的炉门，拦焦车打

开同一炉室焦侧的炉门并把导焦栅插入炉室中，熄焦车位于拦焦车下侧准备接焦，

当三车都已准备就绪后，推焦车开始进行推焦操作，将红焦推到熄焦车的熄焦罐中，
