摘要
介绍了一种基于MCS-51单片机的现场总线型分布式火灾报警控制系统。该系统具有以下特点:用简单的机器语言表示最基本的逻辑原型,为联动编程提供了良好的人机界面;采用现场总线结构,容易实现网络集成;网络通信采用同步计数顺序争用多址接入技术,使集中机摆脱了对区域机的巡访,增强了系统的分布化程度,提高了设备的利用率。系统结构灵活、使用方便,可满足大、中、小各种规模的火灾报警及消防控制的要求。
A fieldbus type of distributed fire alarm control system based on single chip microcomputer MCS-51 is introduced. This system possesses features as follows： Most basic logical original types are expressed as simple machine languages, eonstrueting a fine men- machine interface; Fieldbus structure is adopted,making network integration be implemented easily; The method of synchronous count - sequential capture multi - access is adopted in network communication, freeing central unit from roll - polling regional units, and improving level of system distribution, and enhancing utilization factor of equipment. This system is flexible in structure,convenient for use, it will meet the needs of all kinds of fire alarm and fire control.
