低速总线的应用与实时性问题

The application of low rate serial bus and its real time realization

在建筑设备监控的一些特定领域,串行通信总线的低速应用仍具有其实际优势与经济意义。但串行通信总线的低速率与应用系统的实时性及通用性要求之间存在矛盾。本文从常见的低速总线应用系统的特点出发,提出并实现了一种具有"通用性"与"实时性"的通信程序算法。

In some special situations of the monitoring of electrical equipment in buildings, the application of low rate serial bus is of practical advantage, but the application of which may conflict with the real time realization and generality of the monitoring system. In light of the features of common monitoring system of low rate serial bus, an algorithm for communication programming that can realize both real time and generality is presented.
