摘要
介绍了一种基于VB6.0和S7-200 PLC的液压支架试验台监控系统的组成、通信原理与实现及关键部分的设计等。该系统采用IPC-610-H工控机和S7-200 PLC组成上、下位机控制系统,上位机开发平台选用VB6.0,利用其中的MSComm控件实现了上、下位机的通信;采用ODBC数据库访问技术增强了面向用户的数据管理功能,实现了试验数据的存储与查询;下位机实现了液压支架试验的过程控制和数据采集功能。试验结果及实际应用表明,该系统可实现液压支架试验台的自动控制,保证液压支架的各项试验可靠进行,准确地完成液压支架内循环加载过程的实时监控任务。
The paper introduced composition, communication principle and implementation and design of key parts of a monitoring system of hydraulic support test-bed based on VB and PLC. The system uses IPC-610-H industrial computer and S7-200 PLC to build up control systems of upper computer and lower computer. The development platform of the upper computer selects VB6.0 which MSComn control is used to realize communication between the upper computer and the lower computer. ODBC database access technology is used to enhance user-oriented data management function and realize storage and query of experiment data. The lower computer realizes functions of process control and data collection of hydraulic support test. The test result and actual application showed that the system can realize automatic control of hydraulic support test-bed and ensure each test for hydraulic support to be finished reliably, and can complete real-time monitoring for loading process of internal circulation of hydraulic support.
