【Abstract】 Shock signal, environmental factors often make the electronic burdening scale apparatus loses the accuracy when the scale is used under the abominable conditions. Aiming at these problems,the digital filter,software trap,“Watchdog”,instruction redundant,input and output software design methods of anti-interference are used in MCS-51 microcomputer series software system to improve the system’s dependability.The software design authors put forward can reduce effectively the influence of the shock signal on the measurement accuracy and the reliability of the scale through purifying the signal of measurement.更多还原
