【摘要】：随着煤矿开采强度、开采深度的增加以及机械化程度的提高,在采煤过程中产生的粉尘也越来越多,粉尘的存在严重威胁着井下人员的健康及矿山的安全,为了满足安全矿山和绿色矿山建设的需求,必须对煤矿井下的粉尘加以有效的防治,综采工作面是粉尘产生的主要源头,必将是粉尘防治的重点之处。煤矿井下治理粉尘的措施有很多种,本文在参考国内外多种降尘系统的基础上,结合我国煤矿综采面的现有状况,提出了基于CAN总线的高压、恒压喷雾降尘系统,有效的解决了传统喷雾降尘系统雾化效果差、耗水量大、通信不便、难以降低呼吸性粉尘等的缺点。该系统针对综采工作面的割煤、移架、放煤、运煤等主要产生粉尘的生产环节,分别设计了具有针对性的喷雾降尘控制方法,对综采面粉尘浓度的降低卓有成效。本文根据高压喷雾独有的优势,设计了基于CAN总线、恒压、高压喷雾降尘系统,该系统井下部分主要由主控制器和喷雾控制器组成,喷雾控制器主要用于采集传感器的信号及控制球阀的开／关；主控制器主要用于数据处理、显示、输入参数及控制增压水泵以保持管道中水压恒定等,主控制器和喷雾控制器通过CAN总线来实现数据交换。地面监控中心通过安装于计算机里的上位机软件与主控制进行数据的交换,实现地面与井下的信息交互。其中主控制器采用STM32处理器,喷雾控制器采用ATMega8处理器,CAN总线电路采用MCP2515总线控制器和TJA1050总线驱动器。该系统通过实验表明：该系统方案设计合理,降尘效果显著,满足煤矿企业的需求,具有很好的市场前景和推广价值。
[Abstract]:With the increase of mining intensity, mining depth and mechanization degree, more and more dust is produced in the process of coal mining. The existence of dust seriously threatens the health of underground personnel and the safety of mines. In order to meet the needs of the construction of safe mines and green mines, it is necessary to effectively prevent and cure the dust in coal mines. The fully mechanized coal face is the main source of dust production and will be the focus of dust prevention and control. There are many kinds of measures to control dust in coal mine. Based on the reference of various dust control systems at home and abroad and the existing situation of fully mechanized coal mining face in our country, a high pressure and constant pressure spray dust control system based on CAN bus is put forward in this paper. It effectively solves the disadvantages of the traditional spray dust control system, such as poor atomization effect, large water consumption, inconvenient communication, difficult to reduce the breathing dust and so on. Aiming at the production links of coal cutting, moving frame, coal drawing and transporting coal in fully mechanized coal face, the system has designed the corresponding spray dust control method, which is very effective in reducing dust concentration in fully mechanized coal face. According to the unique advantages of high pressure spray, this paper designs a dust control system based on CAN bus, constant pressure and high pressure spray. The downhole part of the system is mainly composed of main controller and spray controller. The spray controller is mainly used to collect the signal of the sensor and control the opening / closing of the ball valve, and the main controller is mainly used for data processing, display, input parameters and control of the booster pump to keep the water pressure in the pipeline constant, etc. The main controller and spray controller can exchange data by CAN bus. The ground monitoring center exchanges the data with the master control by the computer software installed in the computer to realize the information exchange between the ground and the underground. The main controller uses STM32 processor, the spray controller adopts ATMega8 processor and can bus circuit uses MCP2515 bus controller and TJA1050 bus driver. The experimental results show that the scheme of the system is reasonable, the dust control effect is remarkable, and the system meets the needs of coal mining enterprises. It has a good market prospect and promotion value.
