【摘要】针对当前实验室内测定不同瓦斯吸附压力条件下的煤钻屑瓦斯解吸指标值Δh2的过程存在步骤繁琐、qy288千亿国际程度低、人为干扰因素较多的问题,设计了一种基于单片机控制的高精度煤钻屑瓦斯解吸指标Δh2自动测定系统。该系统以Atmega16单片机为核心,以USART_HMI触摸屏为系统指令输入及显示输出装置。单片机通过识别触摸屏发送的指令对各种传感器、继电器、电磁阀进行操作,完成煤样的自动脱气、吸附、卸压、测定等过程,最终测得煤钻屑在不同瓦斯吸附压力条件下的解吸指标Δh2值。测试结果表明,与现有煤钻屑瓦斯解吸仪相比,该自动测定系统相对误差控制在5%以内,具有良好的实用性和较好的数据准确性。
【Abstract】In view of problems of many steps, low automation degree and more human interference factors in current measuring process of drilling cuttings gas desorption index Δh2 under different gas adsorption pressure conditions in laboratory, a high precision automatic measurement system for coal drill cuttings gas desorption index Δh2 based on single-chip microcomputer was designed. The system takes Atmega16 single-chip microcomputer as the core, and takes USART_HMI touch screen as input and output devices of system instructions. The single-chip microcomputer is used to operate various sensors, relays and solenoid valves to complete process of automatic degassing, adsorption, pressure relief and determination of coal samples through identifying touch screen instructions, so as to obtain final measured coal drill cuttings adsorption pressure desorption index Δh2 under different adsorption pressure conditions. The test results show that the relative error of the automatic measurement system is controlled within 5% compared with the existing coal drill cuttings gas desorption instrument,which has good practicability and data accuracy.
