Abstract
A hotel room's digital terminal based on a single chip microcomputer and Ethernet is designed. "Service project inquiry, traffic information, weather information, telephone number query, the waiter call" and "harmful gas monitoring, alerting, guests keyless locks and remote control functions such as room" by the digital terminal to provide customers for the hotel rooms, accelerate the process of digital provides effective solution. The digital terminal by Phillips ARM7 based single chip micro controller LPC2136 and Microchip Company Ethernet controller ENC28J60 composition, through the transplantation of TCP/IP protocol; so that the digital terminal can be freely accessed local area network and server t o realize the high speed communication. In the article, the Ethernet controller ENC28J60 bottom-lever driver, as well as in the LPC2136 system platform to achieve TCP/IP protocol process was expounded. Designed dimension navigation keys and dot matrix LCD constitutes a good and easy to use interface, so that customers more convenient operation the digital terminal.关键词
