现如今,随着我国经济及科技领域的快速发展,微型计算机技术的发展也变的十分迅猛,在各种仪表设备中几乎都能找到它们的身影,使仪器设备变得智能化、自动化,大幅提高了仪表仪器的使用性能,使仪器仪表的更高效、更高质的运行。智能仪器仪表不同于常规类型的仪器仪表,相较于常规类型的仪器仪表,智能仪器仪表所占据的优势更多,缺点更少。常规类型的仪器仪表在运行的过程中需要保证各构成系统元件的正常,各单元运行正常,才能够实现输入量准确性及稳定性,不过在运行的过程中如果出现异常干扰信号介入的话,就会使输入量产生变化,导致运算过程出现偏差,从而使输出结果的准确性严重下降,干扰信号一旦消失,系统就会立即恢复正常运行。智能仪器仪表在运行的过程中也会出现问题,但这一问题并不是元器件损坏导致的,导致其出现问题的主要原因就是严重干扰。文中就智能仪器仪表中单片机的抗干扰措施进行讨论。

Nowadays,with the rapid development of economy and science and technology in our country,the development of microcomputer technology has become greatly rapid.Almost all kinds of instrument equipment can be found,which makes the instrument and equipment intelligent,automatic,greatly improves the performance of instrument and meters,and makes the instrument more efficient and higher quality operation.Intelligent instrument and meter is different from the conventional type of instrument,which has more advantages and fewer disadvantages than the conventional type of instrument.In the process of operation of conventional instruments and meters,it is necessary to ensure the normal operation of components of each system,and all units operate normally to realize the accuracy and stability of input quantities.However,if abnormal interference signals are involved during operation,the input quantity will be changed,resulting in deviation in the operation process,so that the accuracy of output results will be greatly reduced.Once the interference signal disappears,the system will immediately return to normal operation.There will also be problems in the operation of intelligent instruments,but this problem is not caused by the damage of components,and the main reason for the problems is serious interference.In this paper,the anti-interference measures of single chip microcomputer in intelligent instrument are discussed.
