摘要
提出了基于二总线技术的模拟量监测系统的工作原理及系统构成,同时也介绍了一种适用于二总线通讯、可以进行地址编码巡检,并可以串行数字量传送模拟量的专用集成电路QA840119。
The working theory and the make-up of the two-wire analog system is interpreted, in addition, automatic synchronization communication decoder IC-QA840119, which has the function of A/D conversion and translating analog value by means of digital code, is introduced in this article, with which a practical two-wire analog fire detecting circuit is developed as well.
