【摘要】 针对目前火灾报警系统早期失效或灵敏度下降等问题，应用系统可靠性数字仿真原理，对火灾报警系统进行结构分析，建立起多通道火灾报警系统的失效树，并确定了可靠性数字仿真模型，编制了仿真软件。实例表明，该方法简便、快速、经济，仿真结果与实际相符，在火灾报警系统维修期预测方面有实用价值。更多还原

【Abstract】 n view of the problem that fire prevention units are difficult to carry out reliability test of Fire Report Systems (FRS), a technology of reliability figure emulation is presented. Through analysing the structure of FRS, a spent-tree of FRS with multiple-channel is built, and an emulation-software is wrote out. Running results show that the way of reliability figure emulation is more simple and operational both quickly and ecmomically; the emulation result is corresponded to reality.更多还原
