| Abstract: | A system of keyboard input which is based on the single chip microprocessor(AT.89C51) control is introduced. Using two different keyboard workings which are interrupt scan and programe scan, the input of many function keys and many number keys is achieved. Meanwhile, The principle chart of its hardware circuit and the flow chart of its software are presented. This system has applied to the demodulation system of fiber Bragg grating sensors. The experiment results show that this system has the simple control circuit, good anti-jamming ability, good stability and high practical value. |
