Abstract: To solve the elevator special equipment inspection problems,such as inefficient real-time data processing and more subjective factors in on-site risk assessment,a portable intelligent data analyzer is studied.The design applies  ARM chip as the core of the data analyzer and a  man-machine interface with TFT color display and touch screen.The analyzer is  of small size and  low power consumption,and it can immediately measure data with high efficiency.

Key words: special equipment, portable, embedded, man-machine interface
