数据电台在选矿自动检测及控制中的应用研究
|
摘要
随着选矿技术的迅速发展,新技术、新工艺、新设备、新方法不断涌现。对矿石破碎、磨碎、分级、选别、过滤脱水、精矿出厂和尾矿处理等过程进行自动控制,实现选矿生产过程自动化,可以大大提高劳动生产率,提高选矿回收率和精矿品位,改善劳动条件,降低药剂和电能的消耗,使选矿生产更加经济合理。
本文有别于传统选矿控制中采取的有线通讯方式,采用了基于数据电台无线通信的选矿自动检测及控制应用方案。虽然,就所有的控制应用来说,无线方式并非是最经济的,但是针对选矿自动化领域某些复杂的通信问题,例如被控设备相对较远,测控点过于分散,条件复杂,布线困难等情况下,采用无线通信要优于有线通信,有时甚至也是唯一的解决方案。无线通讯不需要有形的传输媒介,不受布线、环境、距离等诸多因素的限制,具有投资小、易维护、可扩展性强等特点,这对于设备数量多、分布广的工业生产过程,相比于有线传输更具有优势。
本文以选矿厂磨矿分级控制系统为研究背景,结合现有有线通信线路,将数据电台无线通信技术、组态软件及PLC控制技术相融合,研究了基于数据电台的选厂磨矿分级无线测控系统。并根据ModBus RTU通信协议,在西门子STEP7编程环境及“组态王6.5”的命令语言编辑环境下,编写了监控软件与PLC的通信程序,实现了在“组态王”运行环境下,监控软件通过数据电台与下位机PLC系统的无线通信,从而扩展了组态软件及PLC在选矿自动控制中的应用领域。
文中研究的无线测控系统主要由PLC、数据电台和工控机三部分组成。根据选矿厂的实际需要,系统为数据采集、设备控制、远程监控的三级测控体系。为便于系统扩展,工控机与PLC间采用主从式分布结构,通过数据电台实现远程通信。
数据电台无线通信技术在选矿自动控制中的应用,使得整个选厂自动控制系统的组网更加灵活、简单。同时,也为在复杂的选矿工艺下实现选厂的综合自动控制提供了一条新的解决途径。
Along with the rapid development of mineral processing, new technologies, new crafts, new equipments and new methods emerge ceaselessly. The automatic control is adapted during the process of ore stave, grinding and classification, filtration dehydration, ore concentrate exwork and debris processing, all above help the realization of dressing production process automation and enhance the labor productivity and the dressing returns-ratio and the ore concentrate personal status greatly, the improvement of work condition and reduction of the medicament and the electrical energy consumption cause the dressing production to be more economical and reasonable.
This article studies the topic in a different way from the traditional dressing control which always apply wired telecommunication,dressing automatic detection application plan based on the data broadcasting station wireless communication was used. The wireless way by no means is most economical, but in view of dressing automation domain certain complex correspondence question,for example in environments where accusation equipment is relatively far and the craft is too disperses, the condition is complex, the operating mode is danger, situations and so on in wiring difficulty, uses the wireless correspondence to have surpasses the line-wire communication the characteristic, sometimes even also is the only solution.The wireless communication does not need the visible transmission medium, the wiring, the environment, the distance and so on many factor limits, does not have invests slightly, effective quick, easy to maintain strongly, the extendibility and so on the characteristics, this regarding equipment quantity many, distributed broad industrial production process, compares has the superiority in the wired transmission.
This article takes the grinding and the classification control system in the mineral separation plant as the research object, the union existing line-wire communication line, the data broadcasting station wireless communication, the configuration software and the PLC control technology fuses, the research designed the grinding and the classification wireless observation and control system based on the data broadcasting station.And acts according to ModBus RTU communication protocol, in Simens STEP7 programming environment and "Kingview 6.5" under the command language editor environment, compiled has monitored the software and the PLC signal procedure, has realized in "Kingview" under the movement environment, monitored the software through the data broadcasting station and the lower position machine PLC system wireless correspondence question, thus expanded the useage of configuration software and PLC in the dressing automatic control application domain.
In this article constructs the wireless observation and control system combined by PLC, the wireless data broadcasting station and the IPC three parts to be composed.According to the ore dressing plant actual need, the system design three level of monitoring systems which from field data gathering, the equipment scene control, the long-distance equipment monitors.In order to be advantageous for the system to expand, the IPC and PLC uses the host from the type distribution structure, carries on the long-distance correspondence through the data broadcasting station.
The data broadcasting station wireless communication in the dressing automatic control application, causes the network of entire dressing automatic control system to be more flexible and simple.At the same time, also for under the complex dressing craft, the realization the mineral separation plant the complex automatic control to provide a new access to the process.
