Design and implementation of meteorological information monitoring system based on LPC2368

摘要

In order to accelerate the networking process and improve transmission performance, we investigate the com-ethernet protocol conversion module based on LPC2368, and introduce this module into meteorological information monitoring system. Both the hardware and software designs of the module have been carefully considered in this paper. In hardware design, how to extend 2M rather than flash using SPI bus as storage is presented. In software design, how to transplant ucos-ii operating system and reduce TCP/IP protocol stack to MCU LPC2368 is also described. The practical applications of the proposed module in monitoring system have shown that it can transmit data to remote monitoring centre fast and accurately, and has good real-time performance and reliability.
