摘　　要：为了解决目前市面上大部分独立式电气火灾监控探测器普遍具有的成本高、结构复杂、故障率偏高等问题,将火灾自动报警领域的成熟技术—二总线技术应用到了探测器的设计中,进行了相关产品和技术的分析研究,并结合目前在电气火灾监控系统领域中已经存在的基于二总线技术的探测器产品,提出了一种基于二总线技术的非独立式剩余电流式电气火灾监控探测器的设计方法;制定了适用于电气火灾监控系统的二总线通信协议,给出了相关的软件及硬件的设计方案。研究及实践应用结果表明,该设计切实可行、工作稳定,可以应用到电气火灾监控系统中。Aiming at high cost, complex structure and the high failure rate of independent fire monitoring detector used on the market, the two-bus used in the automatic fire alarm field was used in the design of detector. After the analysis of related products and technologies, and the comparing with the detector based on the two-bus, which already exists in the field of electrical fire monitoring system, the design idea of current electrical fire monitoring detector based on the two-bus was established. Then, the two-bus communication protocols applicable to electrical fire monitoring system were formulated, what is more, the hardware and software structure of the design were given. The results indicate that the design is practicable, and the detector can stably work, and the detector can be applied to the electrical fire monitoring system.
