【摘要】：矿井排水系统承担着煤矿主要的涌水排出任务。目前,我国大多数矿井排水系统仍采用人工监测、继电器控制的方法,而由继电器控制的矿井排水系统可靠性不高、应急能力较差,存在一定的安全隐患。本文在查阅矿井排水系统相关文献的基础上,结合嵌入式PLC技术及传感器技术,研发设计了基于嵌入式PLC的矿井排水监控系统。参考目前常用的水泵房构建原理和设计方法,确定了矿井排水系统整体架构,结合监控系统实际功能需求,对水泵、传感器等重要元器件进行可合理选型。确定矿井排水监控系统总体方案,并给出排水系统控制策略。分析现有自动化排水系统控制器原理,充分利用嵌入式PLC成本低、兼容性好、可拓展性强等优势,对矿井排水监控系统下位机进行了开发。选用ATMEL公司推出的AVR系列单片机ATMEGA169作为控制器的主控芯片。首先完成了电源及复位模块的设计。其次利用ATMEGA169的内部嵌入式功能,在其内部8路10位精度A/D转换器基础上,完成了模拟量采集模块的设计;在其内部USART基础上,完善了与上位机的串行通信模块设计。然后结合系统实际功能需求,实现了控制输出模块设计。最后完成了系统程序的设计与编写。在下位机系统开发完成的基础上,利用VC++6.0软件开发平台,采用模块化设计思想,对监控系统上位机监控软件进行开发。选择双向链表结构作为梯形图程序的底层数据存储结构,采用正向深度优先扫描算法完成梯形图程序向语句表的转化。以C语言作为指令表语句向下位机目标代码转换的中间过渡代码,并利用AVRStudio软件平台的G-CC编译实现C语言向目标代码的转换,从而实现了整个嵌入式PLC控制器的开发。利用串口采集和数据库技术实现了排水监控系统参数监测显示功能。最后,在实验室现有条件下,搭建了排水监控系统验证平台,对系统可行性进行了验证。
[Abstract]:The mine drainage system is responsible for the main discharge task of coal mine water gushing. At present, most mine drainage systems in China still use manual monitoring and relay control methods. However, the mine drainage system controlled by relay is not reliable and has poor emergency ability. On the basis of consulting relevant documents of mine drainage system, combined with embedded PLC technology and sensor technology, a mine drainage monitoring system based on embedded PLC is developed and designed in this paper. Referring to the construction principle and design method of water pump room in common use at present, the whole structure of mine drainage system is determined. According to the actual function requirement of monitoring system, the important components such as water pump and sensor can be reasonably selected. The overall scheme of mine drainage monitoring system is determined, and the control strategy of drainage system is given. By analyzing the principle of the existing automatic drainage system controller and making full use of the advantages of embedded PLC, such as low cost, good compatibility and strong expansibility, the lower computer of mine drainage monitoring system is developed. ATMEGA 169, a series of AVR microcontroller produced by Atmel, is chosen as the main control chip of the controller. First, the design of power supply and reset module is completed. Secondly, using the embedded function of ATMEGA169, the analog data acquisition module is designed on the basis of 8-channel 10-bit precision A / D converter, and the serial communication module with host computer is perfected on the basis of USART. Then the design of the control output module is realized according to the actual functional requirements of the system. Finally, the system program is designed and written. On the basis of the development of the lower computer system, using the software development platform of VC 6.0 and adopting the modular design idea, the monitoring software of the upper computer of the monitoring system is developed. The bidirectional linked list structure is chosen as the bottom data storage structure of the ladder diagram program, and the forward depth first scanning algorithm is used to complete the transformation from the ladder chart program to the statement table. C language is used as the intermediate transition code of the target code conversion from the instruction table statement down to the bit-machine, and the G-CC compiler of AVRStudio software platform is used to realize the conversion from C language to target code, thus the development of the whole embedded PLC controller is realized. The parameter monitoring and display function of drainage monitoring system is realized by serial port acquisition and database technology. Finally, under the existing conditions in the laboratory, a water monitoring system verification platform is built, and the feasibility of the system is verified.
