一种实用的智能仪表防“死机”方法

Novel method of preventing intelligent instrument from dying

“死机”是智能仪表的一大顽症。文章中提出新颖实用的智能仪表“防死机”的方法——硬件定时复位法,介绍该方法的硬件、软件设计思路和在IC卡预付费电能表等智能仪表中的应用情况。实践证明:采用硬件定时复位法,可以完全解决一类智能仪表易死机的问题。

＇Dying＇ is a critical problem of intelligent instrument. A novel method of preventing intelligent instrument from dying based on hardware reset was proposed in this paper. Hardware, software design principle of this method was introduced. Application of this method in pre-payment power meter with IC card was also discussed. It has been proved by practice that dying of intelligent instrument can be solved completely by using hardware reset method.
