摘 要:
为了能够准确有效地列工业现场的可燃气体进行连续自动的多点检测,设计一种基于工业以太网技术的可燃性气体报警器。采用高性能的微处理器芯片LPC2214为主芯片,并在LPC22141-移植嵌八式操作系统μC/OS-11和TCP/IP协议栈μIP,作为该报警器应用程序的开发平台。实现了现场气体远程检测,具有气体浓度显示和声光报警功能,并且提供了工业以太网接口,可以将检测到的数据通过工业以太网上传给上位机。为工业以太网现场设备的设计提供了可以借鉴的方法和应用范例。[著者文摘]

Research And Development Of Combustible Gas Alarm Based On Industrial Ethernet
Abstract:
One kind of combustible gas alarm based on industrial ethemet is designed so as to automatically and continuously detect combustible gas in industrial production sites in several positions accurately and effectively. In the design, the high performance microprocessor LPC2214 is adopted as main chip. The embedded operating system ~tC/OS-II and the TCP/IP protocol stack uIP running on the LPC2214 constitute a development platform of application of combustible gas alarm.This combustible gas alarm, which has function of display of density of combustible gas and soundqight alarm, realized remote detection of combustible gas in industrial production sites and sends the data of detected to the PC through the ethernet interface. The designed project provides a kind of method and applied example which can be used for reference to design of industrial devices based on industrial ethernet.[著者文摘]
