| 摘 要： | 智能化仪表与普通仪表的区别主要在于,智能化仪表具有自检和自校正功能。通常是用硬件检测接口电路对外设状态的检测得到外设是否正常的结论,该方法存在2个缺陷,一是需要增加硬件检测接口电路;二是一旦检测接口电路发生故障则得到自检的错误结论。针对此问题,提出了几种不需要对外设检测,即能实现对外设自检的简单可靠的方法。

| Abstract: | Intellectualized instruments are able to perform self-detection and self-correction, which distinguish themselves from traditional instruments. Usually the detecting interface circuit is used to detect the peripheral equipment and see if it works well. Such method is sometimes inconvenient because, firstly,we need the hardware of detecting interface circuit; and secondly, if it fails to work, we probably will get wrong results. In order to solve such problems, we have proposed several methods based on self-detection techniques to get the information of peripheral equipments easily. |
