【摘要】：煤炭企业在我国占据着比较重要的经济地位，煤矿的安全要求一年胜似一年，并且煤矿企业对节能降耗，人生安全等逐渐加大要求。通风机在煤矿的安全生产中起到决定性的作用，通风机监控系统软件不仅提高煤矿的节能降耗，提高了煤矿的机械化程度，而且节省人力物力，提高人身安全，具有重要的意义。 矿井通风系统监控软件主要有计算机监控，数据的筛选分析，最终信号的反馈分析发出指令三部分组成。主要是通过对矿井下的风量、温度、风速、风机的运行情况等进行在线监测，，实时反馈数据至主机处理。 本论文从矿井通风机参数的测量原理及各种参数的换算公式的推导入手，可以代理和减少很多不必要的参数测量。通过分析研究传感器的特点，选择合适的传感器，减少传感器对整个系统参数测量过程中的误差。根据变频器的工作原理及特点选择合适的高压变频器，提高风机的运行效率。硬件选用西门子S7-300和CHH100变频器，通过CAN总线方式形成系统通信网络，可以实时观测到通风机的运行情况。系统上位软件采用MCGS组态软件，实现了风机的在线监测、各种数据的上传并转换成图标形式在大屏幕上体现，方便风机检测员对井下通风的运行状态及参数做出正确的分析。采用μC/OS Ⅱ可编程软件，采集风机的各种数据并且实现报警的作用。 结合本课题的工业现场的需求，设计了本系统的组态式监控软件，搭建了软件框架，完成了图形界面、实时数据库系统、趋势图及报表设计等模块的功能设计。实时数据库系统是整个软件设计的重点和难点。整个系统人机对话方便简洁，系统构成灵活，具有较好的通用性和工程推广性。最后对数据的处理和显示等得出实验结果。
[Abstract]:Coal enterprises occupy a relatively important economic position in our country, the safety requirements of coal mines are better than one year, and the coal mining enterprises gradually increase the requirements of energy saving and reducing consumption, life safety and so on. Ventilator plays a decisive role in coal mine safety production. Fan monitoring system software not only improves coal mine energy saving, coal mine mechanization, but also saves manpower and material resources, and improves personal safety. It is of great significance. The monitoring software of mine ventilation system mainly consists of three parts: computer monitoring, data screening and analysis, final signal feedback analysis and issuing instructions. Through the on-line monitoring of the air volume, temperature, wind speed and fan operation under the mine, the real-time feedback data are processed to the main engine. In this paper, the measurement principle of mine ventilator parameters and the derivation of conversion formulas of various parameters can be used to represent and reduce a lot of unnecessary parameter measurements. By analyzing the characteristics of the sensor and selecting the appropriate sensor, the error in the measurement of the whole system parameters can be reduced. According to the working principle and characteristics of frequency converter, select suitable high voltage frequency converter to improve the efficiency of fan operation. Siemens S7-300 and CHH100 inverter are used in the hardware, and the system communication network is formed by means of CAN bus. The operation of ventilator can be observed in real time. The upper software of the system adopts MCGS configuration software to realize the on-line monitoring of the fan. The data are uploaded and converted into icon form, which is reflected on the large screen. It is convenient for the fan inspector to make a correct analysis on the running state and parameters of underground ventilation. 渭 C/OS 鈪
