Design of Master Controller Input Processing Method Based on LPC2292

Because of external environment or man-made factors influence, the input signal and data of master elevator controller can not be judged and computed basis directly, but needs the corresponding processing .Therefore an operating system task should be assigned for input signal processing data, in order to deal with input signal. In this paper it realized switch quantity software filter and processing, analog quantities and high-speed counting input treatment of elevator master controller based on LPC2292 .
