摘要
介绍了检测瓦斯浓度的催化燃烧法。利用P89LPC938单片机和SJA1000CAN控制器构建底层通信节点,设计了基于CAN通信技术的瓦斯测控系统。该系统解决了RS-485通信距离短的问题,并提高了通信可靠性。
The catalytic burning technique to inspect concentration of methane was introduced.Using P889LPC938 single-chip and SJA1000 CAN controller to construct the bottom layer communication node,a methane monitoring system based on CAN communication technique was designed.The system resolves the restriction of short distance for RS-485 communication,and improves communication reliability.
