【摘要】：煤炭开采面临煤自然发火灾害的严重威胁,采空区火灾尤为严重,采取科学可靠的技术方法对采空区自燃发火的趋势进行预测预报是防治采空区火灾的重要手段。传统的煤自燃预测预报的方法存在诸如指标参数单一、布设管线复杂、光纤线路易损坏等缺陷。针对这些问题本文设计开发了一套采空区环境无线监测系统,旨在为采空区煤自燃预测预报提供可靠的技术支持。本文在采空区环境无线监测系统的煤自燃预测预报指标参数选定、系统整体设计、硬件设计及选型、电路设计、软件程序编制和实验研究等方面进行详细说明。本系统采用分体式设计,由一个信号发射单元和一个信号接收单元组成,信号发射单元通过传感器采集CH_4、CO、O_2和温度四种指标参数的信号经过放大、A/D转换处理后在MSP430单片机的控制下通过无线收发模块发送出去。信号接收单元通过无线收发模块发送信号唤醒信号发射单元并接收参数数据,然后经过MSP430单片机的处理和存储后通过液晶触摸屏幕显示,监测人员可以采用触摸屏幕选项的方式对系统功能进行操作,可以实现对数据的查看、保存、删除等。本系统采用C语言编写系统的软件程序,设计了模块化的程序结构,利用MSP-FET430UIF仿真器和IAR软件平台完成系统程序的编写和调试。为保证信号发射单元足够长久的工作时间,系统采用了低功耗设计。本文设计多组实验对开发的系统样机的性能进行检测,通过埋土实验和下水道实验验证了系统无线通信能力和参数采集发送的性能,满足设计要求。本文开发的采空区环境无线监测系统,参数信号通过无线通信方式传输,一次采集多种指标参数信号,采用低功耗的MSP430单片机作为数据处理和控制核心,系统可靠性高,采集参数数据准确,有力的为采空区煤自燃预测预报提供技术支持。
[Abstract]:The coal mining faces the serious threat of the natural combustion disaster of coal, especially the goaf fire. It is an important means to prevent and cure the goaf fire by adopting scientific and reliable technical method to forecast the spontaneous combustion tendency of the goaf. The traditional prediction method of coal spontaneous combustion has some defects, such as single index parameter, complex pipeline layout, easy damage of optical fiber line, and so on. Aiming at these problems, a wireless monitoring system for goaf environment is designed and developed in this paper, which aims at providing reliable technical support for prediction and prediction of coal spontaneous combustion in goaf. In this paper, the parameters of coal spontaneous combustion prediction and prediction are selected, the whole system design, hardware design and selection, circuit design, software programming and experimental research are described in detail. The system is designed separately and consists of a signal transmitting unit and a signal receiving unit. The signal transmitting unit collects the signal of CH_4,CO,O_2 and temperature parameters through the sensor and amplifies the signal. The A / D conversion is transmitted by wireless transceiver module under the control of MSP430 microcontroller. The signal receiving unit sends the signal through the wireless transceiver module to awaken the signal transmitting unit and receives the parameter data. Then the signal receiving unit is processed and stored by the MSP430 microcontroller and displayed by the LCD touch screen. Monitors can use touch screen options to operate the system functions, and can view, save, delete and so on. The software program of the system is written in C language, the modular program structure is designed, and the system program is written and debugged by using MSP-FET430UIF simulator and IAR software platform. In order to ensure the long working time of the signal transmitting unit, the system adopts low power design. In this paper, several experiments are designed to test the performance of the system prototype. The performance of wireless communication and parameter collection and transmission is verified by buried soil experiment and sewer experiment, which meets the design requirements. The wireless monitoring system of goaf environment is developed in this paper. The parameter signal is transmitted by wireless communication mode, and a variety of parameter signals are collected at one time. The low power consumption MSP430 single chip microcomputer is used as the core of data processing and control. The system has high reliability. The data collected are accurate and can provide technical support for the prediction and prediction of coal spontaneous combustion in goaf.
