支架试验台计算机监控系统

摘要
液压支架作为综采工作面的关键支护设备,近年来发展非常迅速。为了满足煤矿开采高产高效的要求,其强度和技术含量越来越高。但由于相应检测设备的不完善,阻碍了新产品的开发和市场推广。因此研制新型液压支架试验台和先进的监控系统,不仅为液压支架检测试验提供了必要条件,而且减轻了劳动强度,提高了检测效率。
本文以FS913型液压支架试验台为控制对象,设计了支架试验台监控系统,主要进行了以下研究工作。
在分析液压支架试验台的结构功能和MT312-2000试验标准的基础上,采用了分级控制方式,以工控机为上位机,PLC为下位机,并分析了监控系统的组成,确定了硬件和软件的总设计方案。
基于监控系统的功能需求,设计了系统的硬件结构。按照安全性、实时性和可靠性的要求,进行了硬件的选型;对电磁阀控制回路、数据采集系统以及上下位机通信进行了设计;分析了系统的干扰来源,并采取了相应的抗干扰措施。
基于模块化的思想,设计了监控系统的软件结构。采用VB6.0开发了具有良好人机界面的上位机软件。根据试验数据流程,通过PowerDesigner完成数据模型和数据库的设计,由此建立了试验信息管理系统,方便了用户权限、试验数据的管理及报表打印。下位机软件按照MT312-2000的工艺要求设计,并利用STEP7进行编程。设计开发了PLC控制程序和压力保护程序,并通过试验参数的智能设置,解决了压力控制的滞后问题。上下位机之间的通信选择了主从方式,其中上位机处于主动地位。通过MSComm控件开发上位机通信程序,下位机则采用自由口通信协议,实现了监控系统的通信。
对监控系统进行了现场调试和分析,试验结果表明,监控系统符合MT312-2000规定的工艺要求,可完成对液压支架的检测试验,且效果良好。
最后对全文进行了总结和展望。
As the key support equipment of the fully-mechanized face, hydraulic support develops very quickly in recent years. For meeting the requirements of high yield and high efficiency of coal mining, its strength and technology content are becoming higher and higher. However, imperfect of corresponding inspection equipments hinders new product’s study and market promotion. So research and development of the new test-bed and the advanced supervisory control system, not only provides essential condition for testing experiments, but also reduces labor intensity and improves test efficiency.
This paper takes the FS913 type hydraulic support test-bed as the control object, completes the design of the supervisory control system, and mainly carries on the following research works.
After the analysis of structure and function of test-bed and MT312-2000 test standard, the paper adopts the hierarchical control mode using IPC as the host computer and PLC as the lower computer. It analyses the composition of the supervisory control system, and then determines the total design scheme of software and hardware.
Based on the function requirement of the supervisory control system, the structure of hardware is designed. It carries out the selection of hardware according to the requirements of safety, real-time and reliability, designs the control loop of solenoid valve, data acquisition system and communication of upper and lower computer, and takes anti-interference measures after analyzing the source of system interference.
On the base of modular method, the function and structure of supervisory control software is designed. The upper computer software with good man-machine interface is developed using VB6.0. On the basis of test data flow, the data module and database are designed by using PowerDesigner, and the test data manage system is built, which is convenient for the management of user authority and test data and the printing of report. In accordance with the technological requirements of MT312-2000, the software of lower computer is exploited. The PLC automatic control procedure and pressure protection procedure is programmed by STEP7. And the delay problem of pressure control is solved by the intelligent setting of test parameters. The communication of upper and lower computer chooses the master-slave mode and the upper computer plays an active role. And the communication is realized by using MSComm, while lower computer chooses free port mode.
The result of the field debugging and analysis shows that the system meets the requirements of hydraulic support test.
Finally, summary and prospect is given.
