【摘要】：矿井泄漏通信的监控系统无论是应对日常工作,还是应对紧急事务、突发性事件都起到了重要的作用。但是,井上与井下之间的调度却采用电话线沟通,这跟不上企业信息化的进程。采用电话线传输信号,又会使井上调度室内信息存储不灵活(如:人工记录的方式,工作量大)。随着数字与网络化的发展,数字与网络传输更能减少外界因素的干扰,提高通信质量。本文在根据企业的技术要求和实际通信状况的基础上,广泛查阅相关技术文献,升级改造现有泄漏通信监控系统,使其能通过网络传输。在确定了系统的总体方案后,重点对通信协议的兼容性、信号的干扰问题和井上监控平台这三方面进行了详细介绍。采用工业控制领域普遍使用的Modbus TCP协议,以保证井上与井下的通信设备之间更好的传输数据。音频信号在采集和传输过程中容易受到噪声干扰,通过数字信号处理技术,采用严格数值计算的方法,滤除音频信号中的杂波。采用TCP技术保证数字信号在网络传输时不出现数据乱序、丢失等问题。选用亚控科技有限公司开发的组态王KingView作为煤矿泄漏通信监控软件的开发平台,处理并监控所有信息。在实验室内,经过多次的调试运行后,连接转换模块与智能广播主机能够可靠连接,整个泄漏通信监控系统可实现通话、录音、广播等功能,并且处于运行状态的广播管理软件能及时反映通信状态。整套系统性能稳定、可靠、安全,能满足企业要求,值得推广使用。
[Abstract]:The monitoring system of mine leakage communication plays an important role in dealing with daily work and emergency affairs. However, telephone line is used for dispatching between well and well. This cannot keep pace with the process of enterprise informatization. Using telephone lines to transmit signals will also make the storage of information in the well dispatching room inflexible (e.g., manual recording, heavy workload, etc.) with the development of digital and networking, Digital and network transmission can reduce the interference of external factors and improve the communication quality. Based on the technical requirements of enterprises and the actual communication situation, this paper extensively consulted relevant technical documents, upgraded and modified the existing leak communication monitoring system. After the overall scheme of the system has been determined, the compatibility of communication protocols is emphasized. The signal interference problem and well monitoring platform are introduced in detail. The Modbus TCP protocol, which is widely used in industrial control field, is adopted. In order to ensure the better transmission of data between the communication equipment in the well and the downhole, the audio signal is easily disturbed by noise in the process of acquisition and transmission. By means of digital signal processing technology, the method of strict numerical calculation is adopted. The clutter of audio signal is filtered. TCP technology is adopted to ensure that the digital signal does not appear the problem of data disorder and loss in network transmission. Kingview KingView, which is developed by Sub-control Technology Co., Ltd., is chosen as the development platform of the monitoring software for coal mine leakage communication. Processing and monitoring of all information. In the laboratory, after many debugging and operation, the connection conversion module and intelligent broadcast host can be reliably connected, the whole leak communication monitoring system can achieve the functions of voice, recording, broadcasting, etc. The broadcast management software in running state can reflect the communication state in time. The whole system is stable, reliable and safe, which can meet the requirements of the enterprise and is worth popularizing.
