Based on the LPC2114 the engine room driving force for environmental monitoring terminal design -- Human-Computer Interface Module Design Abstract With the development of computer technology and popularization of computer room has become the major units of the important components. The engine room of the equipment must always dynamic environment for computer systems to provide a normal operating environment, room management becomes more important, the main topic on the engine room driving force for environmental monitoring system into enough, functions and features. Modular design, to achieve a multi-functional combination. Able to deal with all kinds of data, independence more and more into intelligence. The development of human-computer interface module of the system including hardware and system software design. The hardware design of the main To the various functional modules, including the programme of verification and circuit design, PCB board design and production, Die Pieces of hardware circuit debugging and overall debugging. Software design including the main program, LCD display, button - Input, printers and other routines establishment. Key words: monitoring system; man-machine interfaces; LED display, keyboard, printer
