【摘要】 一直以来不同厂家的消防电子产品，其火灾报警及消防联动系统的总线协议各不一样；甚至同一厂家不同时期的产品，其总线协议也会不一样。通过本文的研究希望能设计一套有关火灾报警及消防联动系统的现场总线协议：在综合了各阶段及各厂家产品总线技术特点的基础上，力求使建立的协议既体现完备性，又具有可发展性。 本文参照工业现场总线，提出了火灾报警及消防联动系统现场总线的三层模型，并分别进行了描述。依据协议描述本文又分别在现场端和控制器端实施了协议实现的设计和验证工作。其中现场端的设计以单片机技术为核心，控制器端的实现以可编程逻辑器件设计技术为核心。 本文的研究成果已应用在KX21分布智能火灾报警系统中。更多还原

【Abstract】 The communication bus protocols of defferent factory’s fire alarm and control systems are defferent from the beginning, and even the protocols of the same factory’s products for defferent stages are not uniform completely. So we wish to design a set of standard field bus protocols for fire alarm and control system by this research : based on the defferent factory’s and defferent stage’s bus technology, the new protocol should be not only self_contained, but also developmental.According to the industry field bus technology, this paper has built three layer model for the bus of fire alarm and control system, and has described each layer. After describing, this paper has also realized the protocol functions respectively at central controller and field unit. In the field unit the core is Singlechip, and in the central controller is Programmable Logic Device.Today this reaserch has already been applied in KX21 distributing intelligent fire alarm and control system..更多还原
