摘要
在煤层气排采后期产气阶段,人工排采存在实时性和精细化难以达到要求等问题,为此,本文对仪表通信技术、自动控制技术、无线通信技术和远程监控技术等方面进行了研究,并且提出了一种基于ARM内核单片机和4G网络的煤层气排采后期远程控制系统。首先通过分析排采后期的主要参数,确定了主控变量。然后依次介绍了硬件系统的整体结构和各模块功能,以及现场终端程序的设计和服务器端程序的架构。最后通过搭建试验台对整套控制系统进行测试。研究结果表明,该系统实现了对各项排采参数的实时监测以及对排采的自动化控制和远程控制,满足了对煤层气排采实时性和精细化的要求。
In the late stage of gas production during coalbed methane （CBM） drainage, artificial drainage is faced with the problem that its real-time performance and refinement of artificial extraction can＇ t meet the required standard. In view of this, the related technology, such as the instrument communication, automatic control, wireless communication and remote monitor were studied, and a remote control system based on ARM kernel microcontroller and 4G network was proposed for CBM after drainage and production. In this paper, the main parameters of the late stage were firstly analyzed to determine the control variables. Then, we also introduced the whole structure of the hardware system and the function of each module , as well as the program design of the field terminal and the program architecture of server. Finally, the whole control system was tested by setting up the test-bed. The results indicated that this system could real-timely monitor the parameters of drainage and the automatic control and remote control of extraction could also be achieved, which indeed made it possible to met the requirements of real-time and refinement for CBM drainage.
