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. |
