两线制智能感烟探测器软硬件设计 摘 要 当前我国经济和技 的发展带来了对高技 、高质量火灾报警产品急剧增长的 市场需求及由此而导致的中外厂家激烈的市场竞争, 并从 量国外先进产品的进 入说明智能化是产品技术发展的必然趋势。本文就目前火灾控制系统的日趋智能 化，侧重介绍以单片机为核心的现场智能单元的设计，如硬件接口电路的设计，传 感器和单片机的选择，以及单片机的程序设计，以实现良好的智能控制，而对于现 场总线协议只做概要论述。 本文参照工业现场总线，提出了火灾报警系统现场总线的三层模型，并分别进 行了简单的描述。通过本文的研究希望能够建立一个较智能，并且安全可靠的火灾 报警系统，完成现场端数据的获得和处理，以及现场端和控制端的良好通信，实现 火灾报警控制系统的及时性，准确性和安全性。 关键词：智能控制，现场总线，总线协议，单片机 III PDF 文件使用 pdfFactory Pro 试用版本创建 两线制智能感烟探测器软硬件设计 ABSTRACT The development of the economic and the technology brings an increase of the marked need for high technology and high quality fire alarm control system, and leads to a keen market competition in domestic and foreign markets. A lot of advanced products are imported. All of this show that intelligence will be the tendency of the development in the fire control system. With the intelligent tendency of the fire alarm and control system, this paper pays a attention to the design of the field terminal unite which based on the core of microchip, such as the design of the hardware interface, the choice of the microchip and sensor ,and the design of the program in the microchip, to finish the well intelligent control, but simply analyzes the bus protocols. 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 simply described each layer.
